For nearly two decades, scientists have been delving into the phenomenon of “cognitive motor dissociation,” a condition in which patients appear unresponsive to standard cognitive tests yet exhibit signs of consciousness when examined through advanced techniques like fMRI and EEG. A recent 15-year study has revealed that nearly one-quarter of such patients may indeed experience a form of hidden consciousness, a discovery that underscores the importance of improving the quality of life for these individuals.

Consciousness remains one of science’s greatest enigmas, with numerous theories attempting to explain its existence. Some even speculate that consciousness may arise from quantum processes beyond our current understanding. Despite the ongoing debates in both scientific and philosophical circles, experts have become increasingly skilled at detecting consciousness, even in individuals who show no overt signs of it.

This progress can largely be attributed to our growing understanding of brain function and the development of sophisticated technologies like functional MRI (fMRI) and electroencephalography (EEG). These tools provide researchers with unprecedented insight into how the brain responds to external stimuli. In a 15-year study involving 241 patients in an unresponsive, “vegetative” state across six research institutions in the U.S., U.K., and Europe, nearly one-quarter of the patients exhibited evidence of consciousness when examined using fMRI and EEG.

This finding sheds light on the relatively understudied disorder known as “cognitive motor dissociation,” where patients do not respond to traditional cognitive tests but show signs of consciousness when asked to imagine specific tasks. The study’s results were published in *The New England Journal of Medicine*.

“Some patients with severe brain injury do not appear to be processing their external world,” explained Yelena Bodien of Massachusetts General Hospital, the study’s lead author. “However, when they are assessed with advanced techniques such as task-based fMRI and EEG, we can detect brain activity that suggests otherwise. These results bring up critical ethical, clinical, and scientific questions—such as how can we harness that unseen cognitive capacity to establish a system of communication and promote further recovery?”

While the discovery of hidden cognition in unresponsive patients is not entirely new, the prevalence of this condition was previously unknown. In 2006, scientists identified consciousness in a patient in Cambridge, England, by asking her to imagine playing tennis. When the brain activity was compared to that of a healthy individual imagining the same task, the results were strikingly similar. To further explore the prevalence of this condition, Nicolas Schiff, a leading neuroscientist at Cornell University and senior author of the new study, decided to conduct additional tests on patients in similar states.

The researchers selected 241 patients who did not respond to conventional bedside cognitive tests. These tests typically include various tasks and questions designed to assess consciousness, as well as executive function, memory, and attention. Like the 2006 patient, the study participants were asked to imagine specific tasks, such as “imagine opening and closing your hand,” and healthy volunteers were asked to perform the same function. The data collected was then analyzed by statisticians at the Icahn School of Medicine at Mount Sinai, who were unaware of which results came from which research group. The analysis revealed that 60 out of the 241 patients displayed signs of consciousness similar to the healthy control group.

“We find that this kind of sharp dissociation of retained cognitive capabilities and no behavioral evidence of them is not uncommon,” Schiff noted in a press statement. “I think we now have an ethical obligation to engage with these patients, to try to help them connect to the world. What we need here is what we in our consortium have been trying to get started for twenty years: a sustained effort to benefit patients who have disorders of consciousness with systematic medical research, technology development, and better clinical infrastructure.”

The growing awareness of the widespread nature of cognitive motor dissociation, coupled with ongoing advancements in brain implant technology, could significantly mitigate the trauma experienced by these patients. Now that we understand that some “vegetative” patients may be aware of their surroundings, it becomes a moral imperative to assist them in leading more fulfilling lives.

In groundbreaking research, scientists have identified a molecule that may reverse cognitive decline and restore lost memories in Alzheimer’s disease, at least in mouse models. The study, published in the Proceedings of the National Academy of Sciences, was conducted by researchers at the University of California at Los Angeles (UCLA) and represents a novel approach to tackling the debilitating effects of Alzheimer’s.

Unlike existing Alzheimer’s treatments, the new molecule, synthesized at UCLA’s Drug Discovery Lab and named DDL-920, operates through a different mechanism. Traditional Alzheimer’s treatments focus on the accumulation of amyloid plaques in the brain, which is widely believed to be a key driver in the disease’s progression. Over the years, scientists have developed various strategies to eliminate these plaques, but with limited success. Recent studies have revealed that even though monoclonal antibodies can remove these plaques, they fail to restore cognitive abilities or reverse memory loss.

UCLA neurologist and lead researcher Istvan Mody pointed out this limitation. “They leave behind a brain that is maybe plaqueless,” Mody explained, “but all the pathological alterations in the circuits and the mechanisms in the neurons are not corrected.” This statement underscores the need for treatments that go beyond plaque removal and address the underlying neuronal dysfunctions associated with Alzheimer’s.

In addition to plaque buildup, another hallmark of Alzheimer’s, particularly in its early to mid-stages, is the disruption of gamma oscillations in the brain. These oscillations are crucial for functions like memory recall, such as remembering a phone number. The decline in these gamma oscillations is one of the processes that DDL-920 aims to target.

The UCLA research team conducted trials using both “wild-type” mice and mice genetically engineered to develop Alzheimer’s-like symptoms, a method that, while effective for research, has raised ethical concerns among some experts. The researchers hypothesized that DDL-920 could counteract the mechanisms that slow down these vital gamma oscillations.

Following two weeks of oral administration of the drug containing DDL-920, the mice with Alzheimer’s were able to perform on par with the wild-type mice in maze tests designed to measure memory and cognitive function. Remarkably, the treated mice also did not exhibit any abnormal behaviors after receiving the drug, suggesting that DDL-920 may not have adverse effects on behavior, which is an encouraging sign for the molecule’s potential as a treatment.

Despite these promising results, Mody emphasized that there is still a significant amount of research needed to determine whether DDL-920 is safe and effective for use in humans. The transition from mouse models to human clinical trials is a complex and often lengthy process, with many promising treatments failing to make it through. However, if successful, DDL-920 could also have implications for other neurological disorders characterized by disrupted gamma oscillations, including autism spectrum disorder, depression, and schizophrenia.

“We are very enthusiastic about that,” Mody said, reflecting on the broader potential of this research, “because of the novelty and the mechanism of action that has not been tackled in the past.” His optimism highlights the significance of this discovery, which could open new avenues for understanding and treating Alzheimer’s and possibly other neurological conditions.

This study marks an important step forward in the quest to find effective treatments for Alzheimer’s, a disease that affects millions of people worldwide and currently has no cure. While the journey from laboratory research to a marketable treatment is fraught with challenges, the discovery of DDL-920 offers a glimmer of hope for those affected by this devastating condition.

On August 15, 2024, India will commemorate its 78th Independence Day with a celestial event featuring a rare alignment of Jupiter and Mars. This alignment will grace the skies over India, offering a spectacular visual treat to the nation’s celebrations.

The event is not just a routine celestial occurrence; it is a remarkable alignment of two of the solar system’s most prominent planets. Jupiter and Mars, both of which are renowned for their distinct and bright appearances, will come together in the night sky, providing a mesmerizing sight for skywatchers across the country.

According to astronomers, this conjunction is a significant event because of the close proximity of the two planets. The alignment of Jupiter and Mars is expected to be particularly striking, as the planets will appear closer to each other than they typically do. “Such alignments are relatively rare and offer a unique opportunity for enthusiasts and the general public alike to witness an extraordinary celestial phenomenon,” noted Dr. Priya Singh, an astronomer at the Indian Space Research Organisation (ISRO).

For those interested in viewing this cosmic display, the best time to catch a glimpse will be just after sunset, when the two planets will be visible in the western sky. This timing allows for optimal visibility as the darkness of the night sky enhances the brightness of the planets. The celestial event will last for several hours, providing ample time for observers to enjoy the sight.

The conjunction of Jupiter and Mars coincides with India’s Independence Day, adding a layer of significance to the celebrations. This rare astronomical event serves as a perfect backdrop for the nation’s commemoration of its freedom and sovereignty. “The alignment of these planets on such an important day is a beautiful reminder of the vast and interconnected universe we are part of,” said Dr. Singh.

The event will be visible from various parts of India, and numerous observatories and educational institutions are planning special events to help the public view and understand the phenomenon. Many local astronomy clubs and organizations will host viewing sessions and educational talks to enrich the experience for spectators. “We are excited to provide an opportunity for people to not only witness this rare event but also to learn more about the science behind it,” stated Anil Kumar, a member of the Delhi Astronomy Club.

In addition to the public viewing events, there will be live streaming of the alignment on various digital platforms, allowing those unable to view the event in person to experience it remotely. This digital approach ensures that people from all over the country can participate in the celebration, regardless of their location. “We want to make sure that everyone has a chance to witness this spectacular alignment, whether they are able to see it in person or through our live stream,” added Kumar.

The alignment of Jupiter and Mars also holds cultural significance, as celestial events have often been associated with various traditions and beliefs in India. The timing of this event on Independence Day adds a symbolic layer to the celebrations, linking the country’s progress and achievements with the grandeur of the cosmos. “The alignment of Jupiter and Mars on this historic day underscores the harmony between our cultural heritage and the wonders of the universe,” remarked Dr. Singh.

As India prepares to celebrate its 78th Independence Day, the conjunction of Jupiter and Mars provides a celestial highlight that will enhance the festivities. The alignment serves as a reminder of the natural beauty and cosmic phenomena that exist beyond our daily lives. It is an opportunity for citizens to pause and reflect on both the significance of their nation’s history and the marvels of the universe.

This unique celestial event will undoubtedly be a topic of conversation and excitement throughout the country. It not only adds a spectacular visual element to the Independence Day celebrations but also fosters a sense of wonder and curiosity about the universe. As people look to the skies on August 15, they will be reminded of both their national pride and the grandeur of the cosmos.

The alignment of Jupiter and Mars on India’s 78th Independence Day promises to be a memorable event for skywatchers and celebrants alike. The rare occurrence provides an additional reason to celebrate and offers a unique way to connect with the broader universe. With various public and educational events planned to mark the occasion, this celestial alignment is set to be a highlight of the Independence Day festivities in India.

The Earth’s rotation and orientation are being affected by human-induced climate change, according to recent research. Although these changes are subtle at first, they could eventually have significant consequences, such as necessitating negative leap seconds, disrupting space travel, and influencing the Earth’s inner core.

A day on Earth typically lasts around 86,400 seconds, but the exact duration of a complete rotation can fluctuate by fractions of milliseconds each year due to various factors, including tectonic plate shifts, the inner core’s rotation, and the gravitational pull of the moon. Now, scientists are realizing that climate change is another factor that will increasingly impact the Earth’s spin.

Over the past few decades, the rapid loss of ice in polar regions, especially in Greenland and Antarctica, has contributed to rising sea levels. The majority of this additional water accumulates near the equator, causing the Earth to bulge slightly at the middle. This redistribution of mass slows the planet’s rotation because more weight is positioned farther from the Earth’s center, similar to how a figure skater slows down by extending their arms.

In a new study published on July 15 in *PNAS*, researchers used an advanced AI program that integrates real-world data with physical laws to predict how the Earth’s rotation will change over time. The findings support a study published in March, which suggested that Earth’s days will lengthen in the future. However, the new AI model provided more precise estimates of how these changes will unfold.

The same research group also published another study on July 12 in *Nature Geoscience*, revealing that the increased water near the equator is shifting the Earth’s axis of rotation, causing the magnetic poles to move farther from the axis each year. This effect has likely been occurring for at least three decades, but the new study predicts that the axis will shift even more than previously estimated.

“We humans have a greater impact on our planet than we realise,” said Benedikt Soja, a geodesist at ETH Zurich and co-author of both studies, in a statement. “And this naturally places great responsibility on us for the future of our planet.”

Slowing Rotation

Earth’s days have not always been 24 hours long. Around a billion years ago, a day on Earth may have lasted only 19 hours before gradually lengthening to the 24 hours we experience today. This change occurs on various timescales; for example, in 2020, Earth was rotating faster than at any point since 1960, but it slowed again in 2021, despite the shortest recorded day occurring in June 2022.

Generally, Earth’s rotation has been slowing over millennia, primarily due to lunar tidal friction, where the moon’s gravitational pull on the oceans drags water away from the poles, lengthening days by about 2.3 milliseconds every century. The new research indicates that climate change is currently lengthening days by about 1.3 milliseconds per century. Based on current global temperature models, this could increase to 2.6 milliseconds per century by the end of the 21st century, potentially making climate change the dominant influence on Earth’s spin.

Potential Consequences

One likely outcome of longer days is the potential need to introduce negative leap seconds, where a second is occasionally removed from the calendar to account for the lengthening days, similar to the concept of leap years. According to the March study, this might need to begin as soon as 2029, to adjust for the lengthened days accumulated over millennia.

In the past, scientists have speculated that implementing negative leap seconds could disrupt the timekeeping systems of computers and smartphones. However, there is debate over how significant this issue might actually be.

The researchers also noted that changes in Earth’s rotation could affect space travel. “Even if the Earth’s rotation is changing only slowly, this effect has to be taken into account when navigating in space — for example, when sending a space probe to land on another planet,” Soja said. He emphasized the importance of closely monitoring these changes.

Additionally, the team warned that shifts in Earth’s rotational axis might influence the rotation of the Earth’s inner core, potentially accelerating the lengthening of days. However, this interaction remains largely speculative and requires further study.

As we continue to alter the planet’s climate, the consequences for the Earth’s rotation and orientation could be profound, highlighting the need for further research and monitoring to fully understand and mitigate these impacts.

Are You as Happy as You Should Be?

The question of whether we are as happy as we should be often keeps me awake at night. This curiosity led me to study and write about happiness. I realized in my 20s that much of what we learn as children doesn’t fully align with psychological well-being. While my parents and teachers expressed a desire for my happiness, they rarely provided credible scientific methods to achieve it.

To bridge this gap, I enrolled in Yale’s free 8-week happiness course, The Science of Well-Being, taught by Yale Psychology professor Dr. Laurie Santos. The course focuses on common flaws in our thinking and approach to happiness. A central concept in the course is the GI Joe Fallacy, developed by Dr. Santos. This fallacy, inspired by the children’s TV show GI Joe, highlights the erroneous belief that merely knowing something is enough to change behavior. Dr. Santos emphasizes, “Merely knowing something isn’t enough to put it into practice. It’s not enough to change your behavior.”

As a self-help writer, I’ve observed that many people consume self-help content as a substitute for actual self-improvement. They feel a sense of progress by reading about the importance of exercise or cold showers but fail to follow through. Similarly, many people take writing courses but do little writing. This behavior is fascinating and ultimately fine if they enjoy it. However, if their goal is to write or be happy, merely studying these topics won’t suffice. The course teaches that understanding happiness requires effort beyond mere comprehension.

When the professor polled the class about what they believed would make them happy, most students were wrong. They listed common goals such as good grades, a good job, marriage, and great money. However, experiments showed that achieving dream internships or other goals didn’t make students happier in the long run. Harvard Professor Dan Gilbert, in his book *Stumbling Upon Happiness*, found that people making $40,000 per year believed that earning $60,000 or $75,000 would make them happy, while those earning $75,000 thought $90,000 would suffice. Although each income increase brought temporary happiness, people quickly reverted to their previous state of satisfaction.

We continuously re-baseline our expectations, leading to a frustrating cycle of restlessness and acclimation, which hinders happiness. How do we counteract this?

Happiness Strategies

One effective strategy is savoring, which significantly boosts well-being. Savoring involves deliberately reflecting on and appreciating experiences after they occur. As part of my assignment, I practiced savoring daily, usually focusing on small, everyday activities. One day, I savored the feeling of being clean after a workout, which always rejuvenates me but often goes unappreciated. Another day, I reflected on the relaxation of reading a book during a rainstorm in Tampa. By the third day, I noticed an improvement in my mood and overall disposition.

This practice can also be incorporated into a daily gratitude journal, where you express thankfulness for small moments (mine takes only 60 seconds). Dr. Santos advises feeling the gratitude as you think about it. Taking photos of things you’re grateful for can also help.

Another key strategy is investing in temporal things, which expire shortly after use. This counters the instinct to acclimate to our environment. Investing in experiences rather than material objects also enhances mental well-being. Dr. Leaf Van Boven’s study found a negative correlation between spending on material objects and mental well-being, while spending on experiences positively correlated with happiness due to their potential for positive reinterpretation over time.

For instance, my wife Laura and I take an annual trip with friends Dan and Rick, usually to Mexico. This trip brings us satisfaction, a sense of reward, and an escape from routine. Reflecting on these experiences provides lasting happiness, unlike material purchases, which offer only temporary joy.

The Bronze Medal Problem

Another impactful concept is the bronze medal problem. Researcher Dr. Victoria Medvec studied photos of Olympic medalists and found that silver medalists often displayed more negative facial expressions than bronze medalists. Bronze medalists were generally happier because silver medalists focused on what they could have done to win gold, while bronze medalists were grateful to have made it to the podium.

As a former swimmer, I relate to this. In high school, I placed second in the 50 free at my state championships, losing by .03 seconds. It took years to get over it. However, a year later in college, I won a bronze medal in the 100 free and was thrilled. These outcomes represent my best and worst athletic memories, illustrating our tendency to compare and dwell on what could have been.

A counterintuitive strategy to combat this is visualizing important aspects of your life not being there. Research shows this exercise leads to greater satisfaction. For instance, I should remember that in the same high school meet where I placed second, I beat the third-place winner by only .05 seconds. Or, when thinking about my spouse, I should consider the chance encounter that led to our meeting and how fortunate that was.

This exercise highlights the importance of appreciating what we have. Beautiful, loving people and simple luxuries are never guaranteed.

Final Thoughts

The course was enlightening and reminded me to prioritize basic health needs. Our bodies are complex chemical experiments, and without proper sleep, exercise, and nutrition, we disrupt our chemical and hormonal balances. For me, sleep significantly impacts my happiness, acting as a supercharger for my mood and energy. A Norwegian study of college students found a clear link between quality sleep and life satisfaction.

I wish you all the happiness life can bring. Invest time in these exercises: practice savoring everyday activities, invest in experiences over material possessions, recognize the GI Joe Fallacy, and make healthy comparisons. Remember, happiness requires effort, not just knowledge. Don’t become the bitter silver medalist in life.

A recent TikTok video from @zachdfilms3 has brought to light a fascinating aspect of English language history: there was once a time when the alphabet consisted of 27 letters instead of the current 26. The video explains that the 27th letter was none other than “ampersand”, symbolized by “&”.

In his video, @zachdfilms3 elaborates, “This is an ampersand and believe it or not it used to be the 27th letter in the alphabet. You see, back in the day, this symbol came after the letter Z and signified the word ‘and’.” This revelation underscores a historical quirk that many might find surprising today.

Historical records and sources corroborate this discovery. According to The Mirror, students reciting the alphabet in earlier times were instructed to include the ampersand by saying “‘per se’ before it,” resulting in an alphabetical recitation that concluded with “Q R S T U V W X Y Z &. And ‘per se &’ ampersand.”

Encyclopedia Britannica adds further insight, noting that ampersand even found its way into nursery rhymes aimed at teaching children the alphabet: “X, Y, and ampersand / All wished for a piece in hand.” This whimsical inclusion highlights the cultural imprint of a letter that, despite its brief tenure in the English alphabet starting from 1835, eventually faded from mainstream use by the end of the 19th century.

The disappearance of ampersand from the alphabet reflects a broader trend in language evolution. English, like many languages, has shed and gained letters over the centuries. Notably, letters such as thorn (þ) and Wynn (ƿ) were once integral but have since been replaced or assimilated into modern letter forms. Ethel (Œ), once pronounced akin to the “oi” in “oil”, and Yogh (ȝ), used briefly for “ch” sounds, similarly fell out of favor as linguistic needs and conventions changed.

Despite these shifts, the question remains whether English will continue to lose letters in the future. Anne Babson, an English instructor at Southeastern Louisiana University, suggests that standardized spelling has stabilized the alphabet compared to the fluid transitions of Middle English into Modern English. Reflecting on potential future changes, Babson remarks, “Most of our high school English teachers would roll over in their graves if ‘quick’ became permanently ‘quik.’ That said, it’s not impossible that we will simplify the orthography of many words the way the ‘drive thru’ has done.”

This sentiment underscores the balancing act between preserving linguistic traditions and embracing linguistic efficiency. As Babson hints, while certain letters like “x” might seem underutilized in current English, their historical and phonetic roles still contribute to the language’s rich tapestry of sounds and meanings.

The story of ampersand and its brief tenure in the English alphabet serves as a reminder of language’s constant evolution. From nursery rhymes to linguistic curiosities, each letter and symbol carries a piece of history and cultural significance. Whether future changes simplify or enrich English orthography, the legacy of letters like ampersand endures, offering glimpses into the ever-changing landscape of language and communication.

While past U.S. and Soviet missions have collected samples from the moon’s near side, the Chinese mission was the first that has collected samples from the far side.

The moon program is part of a growing rivalry with the U.S. — still the leader in space exploration — and others, including Japan and India. China has put its own space station in orbit and regularly sends crews there.

China’s leader Xi Jinping sent a message of congratulations to the Chang’e team, saying that it was a “landmark achievement in our country’s efforts at becoming a space and technological power.”

The probe left earth on May 3, and its journey lasted 53 days. The probe has drilled into the core and scooped rocks from the surface.

The samples “are expected to answer one of the most fundamental scientific questions in lunar science research: what geologic activity is responsible for the differences between the two sides?” said Zongyu Yue, a geologist at the Chinese Academy of Sciences, in a statement issued in the Innovation Monday, a journal published in partnership with the Chinese Academy of Sciences.

China in recent years has launched multiple successful missions to the moon, collecting samples from the moon’s near side with the Chang’e 5 probe previously.

They are also hoping that the probe will return with material that bear traces of meteorite strikes from the moon’s past. With the successful reentry of the probe, scientists will begin studying the samples. (AP)

The quest for immortality is a concept that has intrigued humanity for centuries. While many have sought ways to extend life, futurist Raymond Kurzweil proposes that nanorobots might be the solution to halting human aging and enabling lifespans of thousands of years, as outlined in his latest book and a Wired essay.

The potential for living indefinitely raises numerous concerns, yet the pursuit of anti-aging therapies remains a prevalent focus among scientists. Most aim to decelerate the physical deterioration and prolong life, but Kurzweil’s aspirations are more ambitious.

Kurzweil delves into nanotechnology’s role in this endeavor in “The Singularity is Nearer” and a Wired essay, emphasizing the integration of biotechnology and artificial intelligence. He envisions this combination as a means to mitigate the aging process, thereby extending human life significantly.

Aging, Kurzweil explains, results from the accumulation of cellular errors during reproduction. Many anti-aging treatments target these errors to expedite the body’s natural repair mechanisms, thus decelerating aging. However, Kurzweil suggests that to achieve significant results, the ultimate goal should be to “cure aging itself.”

This ambitious objective is acknowledged by Kurzweil as sounding far-fetched, yet he is optimistic about the future advancements in medical nanorobots. He envisions that billions of these nanorobots will be required to repair and enhance deteriorating organs, maintaining them in optimal condition.

While Kurzweil’s vision is compelling, it’s just one perspective on the future. The notion of millions of nanobots within one’s body may not be appealing to everyone. The feasibility of Kurzweil’s predictions remains to be seen, particularly given the current state of artificial intelligence.

The search for extraterrestrial life has long captivated humanity, yet after decades of investigation, the question of whether we are alone in the universe remains unanswered. Now, a provocative study from Harvard University suggests that aliens might already be among us, living secretly on Earth.

Researchers at Harvard University’s Human Flourishing Program have proposed that “unidentified anomalous phenomena” (UAP), commonly known as UFOs and extraterrestrial beings, could be residing underground, on the moon, or even walking among humans. The study also speculates that UAPs might be spaceships visiting alien friends based on Earth.

The paper notes, “The author became increasingly aware of the depth of evidence and theory that also tentatively supports another extraterrestrial explanation: the ‘cryptoterrestrial’ hypothesis (CTH) – our focus here – which holds that UAP may reflect activities of NHIs concealed here on Earth (e.g., underground) and its environs.”

The study delves into the concept of “cryptoterrestrials” – beings that could be living among us in disguise, originating from Earth’s future, or descending from intelligent dinosaurs. The researchers categorize cryptoterrestrials into four types:

1. Human Cryptoterrestrials:These are technologically advanced ancient human civilizations that were largely destroyed long ago but have continued to exist in some remnant form.

2. Hominid or Theropod Cryptoterrestrials:These represent a technologically advanced non-human civilization consisting of terrestrial animals that evolved to live in stealth, such as underground. These beings could be descendants of ape-like hominids or “unknown, intelligent dinosaurs.”

3. Former Extraterrestrial or Extratemporal Cryptoterrestrials: These entities might have arrived on Earth from elsewhere in the cosmos or from the human future and have concealed themselves in stealth locations, such as on the moon.

4. Magical Cryptoterrestrials: These entities are less like homegrown aliens and more like “earthbound angels.” They relate to the human world in ways that are less technological and more magical, such as “fairies, elves, and nymphs.”

Acknowledging the unconventional nature of their research, the authors concede that their work is “likely to be regarded skeptically by most scientists.” Nonetheless, they urge the scientific community to consider their claims “in a spirit of epistemic humility and openness.” It should be noted that the paper has not yet undergone peer review.

This study arrives amidst other sensational claims, such as a former US intelligence officer alleging that the US government is concealing a UFO “the size of a football field.”

The Harvard researchers’ hypothesis brings a fresh perspective to the ongoing debate about extraterrestrial life, suggesting that the answer to whether we are alone in the universe might be closer to home than previously thought.

The Moon is witnessing an unprecedented rush, with multiple countries and private enterprises setting their sights on lunar exploration. This surge is driven by the quest for resources and dominance in space. As more missions target the Moon, we must ask: are we prepared for this new chapter of lunar exploration?

Recently, China made headlines with images of its flag on the Moon, marking its fourth lunar landing and the first mission to retrieve samples from the Moon’s far side. In the past year, India and Japan also landed spacecraft on the lunar surface. February saw the US firm Intuitive Machines become the first private company to place a lander on the Moon, with many more missions in the pipeline.

NASA plans to send humans back to the Moon, aiming for a 2026 landing with its Artemis program. China has pledged to send astronauts by 2030, with both nations planning to establish permanent bases rather than make brief visits.

However, this new space race, unfolding amid heightened global tensions, risks exporting terrestrial conflicts to the Moon. “Our relationship with the Moon is going to fundamentally change very soon,” warns Justin Holcomb, a geologist at the University of Kansas, emphasizing that the pace of space exploration is now “outpacing our laws.”

The 1967 UN Outer Space Treaty declares the Moon as a common heritage of all humankind, prohibiting any nation from claiming ownership. Exploration must benefit everyone and serve all nations’ interests. While this treaty promotes peace and collaboration, it was shaped by Cold War politics to prevent space militarization, with over 100 countries signing on.

Today’s space age differs significantly, with not only nations but also private companies competing. A notable example is the US commercial mission Peregrine, which planned to take human ashes, DNA samples, and a sports drink to the Moon. Though a fuel leak thwarted the mission, it sparked debate on whether such ventures align with the treaty’s principles of benefiting humanity.

“We’re starting to just send stuff up there just because we can. There’s no sort of rhyme or reason anymore,” says Michelle Hanlon, a space lawyer and founder of For All Moonkind, which aims to protect Apollo landing sites. She cautions that “Our Moon is within reach and now we’re starting to abuse it.”

Despite the rise of private enterprise, nation-states remain pivotal in space activities. Sa’id Mosteshar, director of the London Institute of Space Policy and Law, notes that companies need state authorization for space missions, which are constrained by international treaties.

Joining the elite group of Moon landers brings significant prestige. India and Japan’s successful missions have elevated their status as global space players, promising economic benefits through jobs and innovation.

Beyond prestige, the Moon offers valuable resources. Its surface, seemingly barren, holds minerals like rare earth elements, iron, titanium, and helium, essential for various technologies. The estimated value of these resources ranges from billions to quadrillions of dollars. However, exploiting these resources is a long-term venture, with the necessary technology still in development.

In 1979, a treaty declared lunar resources unclaimable by any state or organization. However, it gained little traction, with only 17 countries, none of which had been to the Moon, ratifying it. Contrarily, in 2015, the US passed a law allowing its citizens and industries to extract, use, and sell space materials. “This caused tremendous consternation amongst the international community,” recalls Michelle Hanlon, but other countries like Luxembourg, the UAE, Japan, and India followed suit with similar laws.

Surprisingly, water might be the most coveted lunar resource. Initially, Apollo mission rocks were thought to be dry, but about a decade ago, scientists discovered traces of water in them. At the Moon’s poles, substantial water ice reserves exist in permanently shadowed craters. This water could support future lunar inhabitants for drinking, oxygen generation, and even as rocket fuel by splitting it into hydrogen and oxygen, facilitating travel from the Moon to Mars and beyond.

The US is pushing for new guidelines on lunar exploration and resource use through the Artemis Accords, which align with the Outer Space Treaty but suggest new rules may be necessary. Over 40 countries have joined these non-binding agreements, but China has not. Some argue that such regulations should be established through the United Nations due to their global impact. “This really ought to be done through the United Nations because it affects all countries,” says Sa’id Mosteshar.

Resource access could also trigger conflicts. While the Moon offers ample space, areas near ice-filled craters are prime real estate. What happens if multiple entities vie for the same location? Establishing bases close together could lead to disputes. Jill Stuart, a space policy and law researcher at the London School of Economics, compares it to Antarctic research bases, suggesting we might see similar setups on the Moon.

First movers may have an advantage, determining the size of their operational zones. “There will definitely be a first-mover advantage,” Jill Stuart says, implying that early settlers could set the standards for others. The US and China, likely the first to establish lunar bases, might shape the rules, potentially embedding their standards into future practices.

The complexity of lunar governance suggests we may not see another major international treaty. Instead, rules may evolve through memorandums of understanding or new codes of conduct. The Moon, our constant celestial companion, is becoming a focal point for space competition. As this new space race unfolds, it’s crucial to contemplate what kind of environment we want the Moon to be and how to prevent it from becoming a stage for earthly rivalries.

The misconception surrounding the date of the next total solar eclipse in North America persists despite clarifications. Many prominent sources erroneously claim that the subsequent total solar eclipse in the United States will take place on August 23, 2044, branding it as the “last for 20 years.”

Contrary to this misinformation, the accurate date for the next total solar eclipse in the U.S. and North America is March 30, 2033—a mere nine years away.

The confusion likely stems from information provided by NASA, where the eclipse on April 8, 2024, is followed by a statement indicating the next occurrence visible from the contiguous United States will be on August 23, 2044. However, it’s essential to note that the term “contiguous” specifically refers to the 48 adjoining U.S. states and the District of Columbia. This clarification comes from Michael Zeiler, an eclipse cartographer at GreatAmericanEclipse.com, whose expertise is reflected in the Atlas of Solar Eclipses spanning from 2020 to 2045.

Now, let’s delve into the details of the upcoming total solar eclipses in 2033, 2044, and the highly anticipated “Greatest American Eclipse” in 2045.

The Next Total Solar Eclipse In The U.S. And North America (After April 8)

Date: March 30, 2033

Location:Alaska, U.S., and Siberia, Russia

Observers in Alaska, specifically in areas such as St. Lawrence Island, Barrow/Utqiagvik, Kotzebue, or Nome, will have the privilege of witnessing a brief totality approximately an hour after sunrise. This captivating phenomenon, reaching a maximum duration of 2 minutes and 37 seconds, will occur amidst the prime season for the aurora borealis, enhancing the experience.

The Next Total Solar Eclipse In The Contiguous U.S.

Date:August 22, 2044

On August 22, 2044, a total solar eclipse with a maximum duration of 2 minutes and 4 seconds will grace the skies over Greenland, northern Canada, and select regions of the United States, including Montana and North Dakota. Notably, areas such as Banff National Park and Jasper National Park in Canada are expected to draw significant crowds, with Calgary and Edmonton falling within the path of totality.

The Next Coast-To-Coast Total Solar Eclipse In North America

Date:August 12, 2045

Location:U.S, Haiti, Dominican Republic, Venezuela, Guyana, French Guiana, Suriname, and Brazil

Less than a year following the total solar eclipse experience in Canada and the U.S., a monumental coast-to-coast eclipse awaits. With totality spanning as long as 6 minutes and 4 seconds, this celestial spectacle will be visible from various locations including Reno, Salt Lake City, Colorado Springs, Oklahoma City, Tulsa, Tampa, Orlando, Fort Lauderdale, and Miami. Notably, Port Saint Lucie, Florida, will host the longest duration of totality in the U.S., attracting substantial crowds to the Kennedy Space Center in Florida.

It’s crucial to recognize that total solar eclipses are not exclusive to the United States, occurring approximately every 18 months. The subsequent occurrence is slated for August 12, 2026, with Greenland, Iceland, and Spain, along with a small portion of Portugal, set to witness this awe-inspiring event.

By accurately understanding the dates and locations of upcoming total solar eclipses, enthusiasts can better prepare to witness these rare and captivating celestial occurrences.

An international research endeavor led by the University of Granada (UGR) and employing artificial intelligence has revealed a significant relationship between human personalities and the expression of genes. This breakthrough provides fresh insights into the intricate dynamics between the mind and body.

The study, documented in Molecular Psychiatry, delves into how an individual’s personality and fundamental perspective on life regulate gene expression, thus influencing their overall health and welfare. This pioneering investigation marks the first instance of gauging genome transcription concerning human personality comprehensively.

Conducted by a collaborative, multi-disciplinary team from the Andalusian Interuniversity Research Institute in Data Science and Computational Intelligence (DaSCI), the UGR’s Department of Computer Science and Artificial Intelligence, and the Biohealth Research Institute in Granada (ibs. GRANADA), the research also involved Professor Robert Cloninger from Washington University in St. Louis, researchers from Baylor College of Medicine in Texas, USA, and participants from the Young Finns Study in Finland.

The Young Finns Study, spanning four decades and encompassing extensive data on participants’ health, physical condition, and lifestyle, served as the foundational dataset. It included thorough personality evaluations covering both temperament (habits and emotional reactivity) and character (conscious goals and values). The results underscored the role of certain life perspectives in either fostering a healthy, gratifying, and prolonged existence or precipitating a stressful, unhealthy, and truncated life span.

This study scrutinized gene expression regulation across individuals, considering three tiers of self-awareness delineated by their combined temperament and character profiles. These levels were classified as “unregulated,” characterized by irrational emotions and ingrained habits tied to tradition and authority obedience; “organized,” emblematic of individuals adept at consciously regulating habits and fostering cooperation for mutual gain; and finally, “creative,” representing self-transcendent individuals adapting habits to live harmoniously with others, nature, or the universe, even at personal cost.

The research yielded two pivotal revelations, elucidated by UGR researcher Coral del Val, a co-lead author of the study. “First, we identified a network of 4,000 genes forming multiple modules expressed in specific brain regions. Some of these genes had been previously associated with human personality inheritance,” del Val explains. “Secondly, we unearthed that these modules form a functional interaction network capable of orchestrating gene expression changes to adapt to diverse internal and external conditions, facilitating our daily adaptation to challenges and directing our development.”

The study highlighted two sub-networks orchestrating these changes: one regulating emotional reactivity (e.g., anxiety, fear), and the other governing what individuals perceive as meaningful (e.g., conceptualization, language production). Elisa Díaz de la Guardia-Bolívar, another co-lead author, notes, “Most notably, these emotion and meaning networks are coordinated by a control center comprised of six genes. It’s intriguing that these six genes are highly conserved across evolution, underscoring their pivotal role in regulating life forms’ functioning.”

Identifying these gene networks and the control hub offers practical insights into enhancing individuals’ health, happiness, and daily life quality amidst ubiquitous challenges and stresses. Igor Zwir from UGR remarks, “Prior research revealed significant disparities in well-being among individuals in the three personality groups, corresponding to their self-awareness levels. Greater self-awareness, particularly among the creative group, correlated with heightened well-being compared to the organized and unregulated groups.”

This study suggests that cultivating a more self-transcendent and creative outlook on life could enhance health and well-being, although further exploration is warranted to ascertain whether gene expression regulation is the mediator between self-awareness and well-being. Nevertheless, interventions promoting greater self-transcendence and mindfulness have demonstrated benefits across various health dimensions, suggesting gene expression regulation could indeed mediate this association.

The study’s innovative computational methodologies facilitated the investigation of intricate biological systems in humans in an ethical, non-intrusive, and beneficial manner, aimed at elucidating pathways to healthy living, as Professor Cloninger emphasizes. He underscores the interconnectedness of mind and body, stressing that each influences the other, advocating for a perspective where past or present conditions don’t singularly dictate future well-being but rather recognizing the potential for self-cultivated well-being through a creative, open-ended process.

NASA aims to revolutionize timekeeping beyond terrestrial norms by introducing a lunar-centric timekeeping system, effectively placing the moon on its own time clock. Rather than adhering to conventional time zones, this novel framework will establish a comprehensive reference for time on the lunar surface. Due to the moon’s lower gravity, time progresses slightly faster there, at a rate of 58.7 microseconds per day compared to Earth. Responding to this intriguing prospect, the White House has directed NASA and other U.S. agencies to collaborate with international counterparts in devising this innovative lunar timekeeping system.

“An atomic clock on the moon will tick at a different rate than a clock on Earth,” explained Kevin Coggins, NASA’s leading communications and navigation official. “It makes sense that when you go to another body, like the moon or Mars that each one gets its own heartbeat.” This customized timekeeping approach signifies that all activities on the moon will align with its accelerated time frame.

Historically, during NASA’s previous moon missions, astronauts relied on conventional watches, with timing being less precise and not as crucial as it is today with the reliance on GPS, satellites, and complex computer systems. Coggins emphasized the significance of microsecond accuracy in interactions among sophisticated technological systems.

The European Space Agency had previously advocated for the establishment of a unified time standard for lunar operations, given that a lunar day lasts approximately 29.5 Earth days. However, the specifics of implementing this new lunar time within NASA’s operations remain to be determined. While the International Space Station continues to utilize Coordinated Universal Time (UTC) owing to its low Earth orbit, determining the transition point for the adoption of the new space time poses a challenge for NASA. Furthermore, fluctuations in Earth’s time, necessitating the occasional addition of leap seconds, further complicate this endeavor.

In contrast to Earth’s observance of daylight saving time, Coggins clarified that such adjustments would not apply on the moon. The ambitious timeline set forth by the White House demands that NASA present a preliminary concept by the year’s end, with a finalized plan expected by the conclusion of 2026.

In the midst of spring, there was a perplexing occurrence: the harvest festivities were underway, yet the fields were far from yielding ripe produce. This puzzling discrepancy dated back to the 1st Century BC when the Roman calendar, in its disarray, failed to align these crucial celebrations with the agricultural reality.

Julius Caesar perceived the urgency in rectifying this chaotic calendar, a task demanding the synchronization of the Roman Empire’s timekeeping with both the Earth’s daily rotation and its yearly orbit around the Sun. His solution birthed a profound transformation – introducing the longest year in history, augmenting and subtracting months, securing the calendar to the seasons, and instituting the concept of leap years. This monumental endeavor, however, encountered a peculiar hurdle in the form of Roman numerical quirks.

Thus, the year 46BC unfolded, known as the Year of Confusion, emblematic of the intricate challenges Caesar and his advisors faced. Helen Parish, a visiting professor of history, elucidates that the early Roman calendar, rooted in lunar and agricultural cycles, comprised only 10 months, leaving significant gaps unaccounted for.

Parish elaborates on Numa Pompilius’ efforts in 731BC to enhance the calendar by introducing additional months to cover the winter period, thereby extending the year to 355 days. However, this number, although aligning with the lunar year, bore superstitions against even numbers, leading to the addition of an extra day. Consequently, February, with its 28 days, became symbolic of purification.

Despite these advancements, the calendar remained approximately 11 days adrift from the solar year, evidenced by historical discrepancies such as the misdated solar eclipse of 200BC. Attempts to rectify this misalignment with ad-hoc intercalary months proved ineffective, often manipulated for political ends rather than seasonal accuracy.

Julius Caesar, advised by the astronomer Sosigenes, undertook bold measures to synchronize the calendar with the Sun, introducing two unprecedented months in 46BC. This decision extended the year to 445 days, paving the way for the abandonment of intercalary months thereafter.

Nonetheless, aligning the calendar with the solar year posed ongoing challenges due to the fractional excess in Earth’s orbit, prompting the introduction of leap years every four years. This adjustment, although initially prone to doubling errors in Roman counting, was eventually rectified by Augustus, solidifying the Julian calendar’s foundation.

Further refinements occurred in 1582 with Pope Gregory’s calendar reforms, introducing adjustments to ensure long-term accuracy, such as skipping leap years on centennial years unless divisible by 400. Despite the calendar’s enhancements, its adoption remained subject to political and religious influences, with dissent over perceived temporal theft by the Papal decree.

Parish highlights the global adoption of the Gregorian calendar over time, albeit with variations across different countries, leading to temporal discrepancies that could perplex international correspondence. Despite its improvements, the Gregorian calendar isn’t flawless, with potential discrepancies looming in the distant future.

Nevertheless, it has afforded humanity a semblance of temporal order, buying time until the next adjustment becomes necessary.

In a groundbreaking discovery, a telescope surpassing the size of Earth has detected a plasma rope in the vastness of the Universe. Utilizing a network of radio telescopes both on Earth and in space, astronomers have unveiled the most intricate view ever captured of a plasma jet emanating from a supermassive black hole situated at the center of a remote galaxy.

The jet originates from the heart of a distant blazar known as 3C 279, hurtling through space at nearly the speed of light and revealing intricate, twisted patterns near its source. Surprisingly, these patterns challenge the conventional theory that has stood for four decades, attempting to explain the formation and evolution of such jets over time.

The Max Planck Institute for Radio Astronomy in Bonn, Germany, played a pivotal role in these observations. The institute facilitated the combination of data from all participating telescopes, creating a virtual telescope with an effective diameter of approximately 100,000 kilometers.

Blazars, a subclass of active galactic nuclei, are the brightest and most powerful sources of electromagnetic radiation in the cosmos. They consist of galaxies with a central supermassive black hole accreting matter from a surrounding disk. About 10% of active galactic nuclei, classified as quasars, generate relativistic plasma jets. Blazars specifically belong to a small fraction of quasars where these jets point almost directly at the observer.

Recently, a team of researchers, including scientists from the Max Planck Institute for Radio Astronomy, imaged the innermost region of the jet in the blazar 3C 279 with unprecedented angular resolution. They detected remarkably regular helical filaments, suggesting a need for a reevaluation of the theoretical models used thus far to explain the processes behind jet production in active galaxies.

Antonio Fuentes, a researcher at the Institute of Astrophysics of Andalusia in Granada, Spain, and leader of the research, expressed gratitude for the RadioAstron space mission, which enabled the highest-resolution image of a blazar’s interior to date.

The new insights into the plasma jet of 3C 279, facilitated by the RadioAstron mission, reveal previously unseen details. The jet, extending over 570 light-years from the center, displays at least two twisted filaments of plasma. Eduardo Ros, a member of the research team, highlighted the complementary role of different telescopes, noting that the GMVA and the EHT observed the inner jet at shorter wavelengths but couldn’t detect the filamentary shapes due to their faintness and size.

Contrary to the previous belief that plasma jets from blazars are straight and uniform, the twists and turns observed in 3C 279, referred to as helical filaments, indicate the influence of forces around the black hole. This led to the realization that the existing theory explaining jet evolution over time is no longer sufficient. Consequently, the astronomers emphasize the necessity for new theoretical models to elucidate the formation and evolution of helical filaments near the jet’s origin.

Guang-Yao Zhao, affiliated with the MPIfR, pointed out an intriguing aspect suggesting the presence of a helical magnetic field confining the jet. This magnetic field, rotating clockwise around the jet in 3C 279, might play a role in directing and guiding the jet’s plasma, moving at an astonishing 0.997 times the speed of light.

Andrei Lobanov, another scientist from MPIfR, highlighted the novelty of the study, connecting these filaments to intricate processes in the immediate vicinity of the black hole producing the jet.

The study, featured in the latest issue of Nature Astronomy, contributes to a better understanding of the role of magnetic fields in the initial formation of relativistic outflows from active galactic nuclei. It underscores the challenges in current theoretical modeling and emphasizes the need for advancements in radio astronomical instruments and techniques for imaging distant cosmic objects at record angular resolutions.

The technological advancements that enabled this discovery relied on Very Long Baseline Interferometry (VLBI), creating a virtual telescope by combining data from different radio observatories. Yuri Kovalev, the RadioAstron project scientist, emphasized the importance of international collaboration, with observatories from twelve countries synchronized to form a virtual telescope the size of the distance to the Moon.

Anton Zensus, director of the MPIfR and a key figure behind the RadioAstron mission, highlighted the exceptional achievements resulting from international scientific collaboration, spanning decades of planning and execution. The success of the mission underscores the significance of connecting large ground-based telescopes and meticulous data analysis for unlocking the mysteries of the cosmos.

In a groundbreaking achievement, an experiment conducted aboard NASA’s Psyche spacecraft has utilized deep space optical communications (DSOC) to transmit a laser-encoded message to Earth from a distance unprecedented in space exploration. The DSOC, part of a two-year tech demonstration riding alongside the Psyche mission en route to the asteroid Psyche, successfully beamed a near-infrared laser carrying test data from a position approximately 16 million kilometers away—about 40 times farther than the Moon is from Earth. This remarkable feat marks a significant milestone in optical communication technology and has the potential to revolutionize spacecraft communication methods.

The Deep Space Optical Communications (DSOC) achieved “first light” on November 14, as reported by NASA’s Jet Propulsion Laboratory (JPL), the entity overseeing both missions. This accomplishment resulted from a precise maneuver where the DSOC’s laser transceiver locked onto JPL’s powerful uplink laser beacon at the Table Mountain Observatory. This alignment enabled the DSOC’s transceiver to direct its downlink laser to the Hale Telescope at Caltech’s Palomar Observatory in California, located 130 kilometers away.

Trudy Kortes, Director of Technology Demonstrations at NASA HQ, highlighted the significance of this achievement, stating, “Achieving first light is one of many critical DSOC milestones in the coming months, paving the way toward higher-data-rate communications capable of sending scientific information, high-definition imagery, and streaming video in support of humanity’s next giant leap: sending humans to Mars.”

While optical communications have been employed in Earth’s orbit previously, this marks the farthest-ever distance covered by laser beams. Laser communication involves the transmission of a beam of photons moving in the same direction at the same wavelength. The advantage lies in the ability to pack vast amounts of data into tight waves, allowing for unprecedented data transmission speeds. The DSOC tech demo aims to demonstrate transmission rates 10-100 times greater than current top radio communication systems, offering the potential for missions to carry higher-resolution scientific instruments and enabling faster communication for deep space missions, such as live video streams from the surface of Mars.

Dr. Jason Mitchell, Director of the Advanced Communications and Navigation Technologies Division within NASA’s Space Communications and Navigation program, emphasized the benefits of optical communication for scientists and researchers, stating, “Optical communication is a boon for scientists and researchers who always want more from their space missions and will enable human exploration of deep space. More data means more discoveries.”

Despite the success of this record-breaking technology demonstration, challenges remain. The precision required to point the laser beam increases with greater distances, and the signal’s photons become fainter, leading to potential lag times in communication. During the November 14 test, the photons took approximately 50 seconds to travel from Psyche to Earth. As Psyche reaches its farthest distance, this travel time is expected to extend to around 20 minutes, necessitating adjustments in the laser positions on both Earth and the spacecraft to account for changes in position.

Meera Srinivasan, Operations Lead for DSOC at JPL, acknowledged the formidable challenge faced by the DSOC and Psyche operations teams, stating, “[The] test was the first to fully incorporate the ground assets and flight transceiver, requiring the DSOC and Psyche operations teams to work in tandem. It was a formidable challenge, and we have a lot more work to do, but for a short time, we were able to transmit, receive, and decode some data.”

Abi Biswas, Project Technologist for DSOC at JPL, encapsulated the achievement by stating, “[We] were able to exchange ‘bits of light’ from and to deep space.” This exchange of bits of light holds the potential to redefine how we communicate in the realm of space exploration, opening up new frontiers for data transmission and scientific discovery.

The universe is a vast realm of enigmatic wonders, and as Halloween approaches, NASA has uncovered some eerie cosmic phenomena. From a haunting “face” on Jupiter to a ghostly skeletal hand-shaped nebula, these celestial discoveries are sending shivers down the spines of stargazers.

Jupiter’s Eerie ‘Face’

NASA’s Juno mission, which has been orbiting Jupiter and its largest moons since 2016, recently completed its 54th close flyby of the gas giant on September 7. During this pass, Juno’s JunoCam instrument captured stunning images of Jupiter’s northern regions along the terminator, the line that separates the day side from the night side.

In these images, observers with vivid imaginations may detect what resembles a Picasso-like face emerging from the turbulent atmosphere. This phenomenon, known as pareidolia, occurs when viewers perceive familiar shapes and objects in random patterns. The raw data from this flyby, publicly available on the JunoCam website, was meticulously processed by a citizen scientist named Vladimir Tarasov. The close proximity of Juno, approximately 4,800 miles (7,700 kilometers) above the planet’s cloud tops, allowed for a dramatic interplay of sunlight and shadows, enhancing the eerie appearance of this celestial face.

X-Rays Reveal Celestial Bones

Over a century ago, physicist Wilhelm Röntgen pioneered the use of X-rays to image the bones of his wife’s hand in 1895. Now, two X-ray telescopes have unveiled the “bones” of a luminous hand-shaped cloud that originated from the aftermath of a collapsing star.

This cloud of gas and dust, a nebula known as MSH 15-52, formed 1,500 years ago when a massive star exhausted its nuclear fuel and collapsed. Situated a staggering 16,000 light-years from Earth, the nebula boasts a remarkable history. When the star underwent its collapse, it left behind a dense remnant, a neutron star. Neutron stars that rotate rapidly and possess powerful magnetic fields are classified as pulsars. These pulsars emit energetic jets and powerful winds, giving rise to this particular nebula.

In 2001, NASA’s Chandra X-ray Observatory initially observed the pulsar, identified as PSR B1509-58, located at the “palm” of the hand-shaped nebula. A distinct jet emerging from the pulsar can be traced down to the “wrist.”

Mapping a Nebula’s Magnetic Field

Fast forward over two decades, and NASA’s Imaging X-ray Polarimetry Explorer (IXPE) embarked on a 17-day observation campaign of the nebula. Launched in December 2021, IXPE recorded its most extended observation period to date. The findings of this operation were recently published in The Astrophysical Journal.

Lead study author Roger Romani, a professor of physics at Stanford University in California, explained, “The IXPE data gives us the first map of the magnetic field in the ‘hand.'” He continued, “The charged particles producing the X-rays travel along the magnetic field, determining the basic shape of the nebula, like the bones do in a person’s hand.” This observation revealed the unique capability of IXPE to identify regions within the magnetic field where particles in the nebula are accelerated by turbulence.

As we approach Halloween, these otherworldly discoveries remind us that the cosmos is a realm of both beauty and mystery, offering glimpses of the extraordinary, even in the farthest reaches of space.

Sir David Attenborough’s latest installment of the Planet Earth series has garnered praise for its breathtaking visuals and poignant storytelling, but it has also evoked a sense of concern and sadness among viewers. The third season of this award-winning program debuted on BBC One, attracting an audience of 5.6 million.

The eight-part series offers a glimpse into the struggles of wildlife across the globe as they contend with ever-changing environmental conditions. The Guardian hailed the first episode as “majestic TV” from the venerable broadcaster, describing it as both awe-inspiring and disconcerting. Rebecca Nicholson, in a five-star review, noted, “It is possible to watch and enjoy it purely for the astonishing footage – but it will horrify you too.” She also emphasized the darker tone of this series compared to its predecessor, highlighting the concerning trends in the natural world.

Narrated by the 97-year-old Sir David, the documentary features footage from drones and remotely operated deep-sea submersibles, collected over a five-year period across 43 countries. The initial episode explores coastlines from Kent to South Africa, Mexico to Australia, and beyond. It presents two cautionary tales centered on the challenges faced by Caribbean flamingos on Mexico’s Yucatán Peninsula and the endangered green turtles of Raine Island on the Great Barrier Reef. The episode also includes vintage footage of a young Sir David visiting the same island more than 60 years ago, highlighting the impact of human activity on these ecosystems.

Carol Midgley of The Times, in a four-star review, praised the series as magnificent but also acknowledged its potential to evoke sadness. She cited examples such as desert lions hunting cormorants in the sea at night, a remarkable sight, but also the distressing scenes of Caribbean flamingos and their nests being destroyed by worsening storms, attributed to climate change. She noted, “Soaked and cold [they] will soon perish unless they can get out of the water. Some years no chicks survive.”

Ed Power of The Telegraph celebrated Sir David’s ability to convey the beauty and fragility of our planet. He marveled at the stunning visuals presented in the series, including mesmerizing shots of flamingos in flight and their vulnerable young struggling to survive in the rain. Power concluded that Sir David’s presence is reassuring at a time of uncertainty in the world.

This season, the series has moved to an earlier time slot to make it more accessible to children, giving them opportunities to connect with and understand the natural world. Sir David emphasized the importance of children’s innate understanding of nature while cautioning against deforestation and the encroachment on natural spaces. He highlighted the need for coexistence with the natural world, asserting that we must accommodate and protect it.

In his review for the Daily Mail, Christopher Stevens found every moment of the opening episode fascinating. He praised the series for being visually stunning, acknowledging that it’s challenging to single out a “best” Attenborough series from the past seven decades but suggested that Planet Earth III could be the most visually spectacular.

The I newspaper’s Gerard Gilbert, in a five-star review, characterized the show as spectacular, eye-opening, awe-inspiring, and terrifying. He underscored that this series reflects the closest Sir David Attenborough has come to despair, conveying a message of urgency to appreciate and safeguard the natural world before it’s too late.

The latest installment of the Planet Earth series has captivated viewers with its stunning visuals and powerful storytelling. It presents both the grandeur of the natural world and the urgent need to protect it, leaving audiences with a profound sense of wonder and concern.

Recent images from the James Webb Space Telescope have unveiled intriguing pairs of planet-like objects in the Orion Nebula that defy previous detection. The Orion Nebula, a luminous cloud of dust and gas, is among the most prominent nebulae in the night sky and is recognizable as the “sword” in the Orion constellation. Situated 1,300 light-years from Earth, this nebula has been a focal point for astronomers, offering a plethora of celestial objects to investigate, including planet-forming disks encircling young stars and brown dwarfs, which are celestial bodies with mass falling between that of planets and stars.

Astronomers employed Webb’s near-infrared camera, known as NIRCam, to capture comprehensive images of the Orion Nebula, spanning both short and long wavelengths of light, thereby unveiling unprecedented insights and unforeseen revelations.

In their examination of the short-wavelength image of the Orion Nebula, astronomers Samuel G. Pearson and Mark J. McCaughrean directed their attention to the Trapezium Cluster, a youthful star-forming region approximately one million years old, teeming with thousands of emerging stars. Among these stars, the scientists identified brown dwarfs, celestial objects too small to initiate the nuclear fusion process characteristic of stars. Brown dwarfs possess a mass less than 7% that of the Sun.

While on the quest to locate additional low-mass isolated entities, the astronomers stumbled upon an entirely novel phenomenon: pairs of planet-like objects with masses ranging from 0.6 to 13 times that of Jupiter. These enigmatic objects appeared to challenge some fundamental tenets of astronomical theories, prompting the scientists to christen them “Jupiter Mass Binary Objects,” or JuMBOs.

Although some of these JuMBOs exceed the mass of Jupiter, they are generally comparable in size, only slightly larger. According to Pearson, a European Space Agency research fellow based at the European Space Research and Technology Centre in the Netherlands, “Although some of them are more massive than the planet Jupiter, they will be roughly the same size and only slightly larger.”

The astronomers’ investigation unveiled a total of 40 pairs of JuMBOs and two triple systems, all of which exhibited wide orbits around one another. Despite their paired existence, these objects typically maintained a separation of about 200 astronomical units, equivalent to 200 times the distance between Earth and the Sun. Completing an orbit around each other required a substantial duration, ranging from 20,000 to 80,000 years.

These enigmatic JuMBOs exhibited a temperature range spanning from 1,000 degrees Fahrenheit (537 degrees Celsius) to 2,300 degrees Fahrenheit (1,260 degrees Celsius). These gaseous entities are relatively youthful in astronomical terms, boasting an age of approximately one million years, whereas our solar system has endured for 4.57 billion years

Mark J. McCaughrean, senior adviser for science and exploration at the European Space Agency, aptly characterized these objects as “3-day-old babies” compared to the age of our solar system. Their continued luminosity and warmth stem from the energy they retained at their formation, allowing them to emit detectable light.

To document their discoveries in the Orion Nebula, McCaughrean and Pearson composed two research papers, which have been submitted for publication in academic journals. Preliminary findings are available on the preprint platform arXiv. However, numerous questions about JuMBOs persist, particularly regarding their origins.

The formation of stars typically originates from massive clouds of gas and dust that succumb to gravitational forces, a process accompanied by the emergence of planetary systems. Nevertheless, existing theories fail to account for the formation of JuMBOs or their presence in the Orion Nebula, as McCaughrean noted. While some might liken JuMBOs to rogue planets, objects of planetary mass that roam through space independently of stars, it remains challenging to explain how pairs of these objects were simultaneously expelled while maintaining gravitational connection.

Pearson emphasized the implications of these discoveries, stating, “Scientists have been working on theories and models of star and planet formation for decades, but none of them have ever predicted that we would find pairs of super low mass objects floating alone in space — and we’re seeing lots of them.” This revelation raises questions about the understanding of both planet and star formation.

The Orion Nebula ranks among astronomers’ favored targets for observation. As telescopes grow in size and sophistication, they reveal an increasing number of objects within this nebula. Pearson underscored the significance of Webb’s infrared capabilities, stating, “JWST is the most powerful infrared telescope that has ever been built, and these observations simply wouldn’t be possible with any other telescope.”

Future observations scheduled for early 2024 may provide further insights into the atmospheric compositions of JuMBOs. Researchers also seek to refine their understanding of these objects by obtaining precise measurements of their masses. Furthermore, investigations focused on other star-forming regions could determine whether JuMBOs are present beyond the confines of the Orion Nebula.

As Pearson summarized, “The main question is, ‘What?! Where did that come from?’ It’s just so unexpected that a lot of future observations and modeling are going to be needed to explain it.”

New research has unveiled a fascinating insight into how people across the world spend their daily 24 hours. With a global population of approximately 8 billion, this translates to an astonishing 190 billion human hours every day. How we distribute this time has profound implications for our environment and life experiences. To gain a deeper understanding of how individuals worldwide allocate their time, a team from McGill University embarked on an extensive study, offering an unprecedented glimpse into a typical day on our planet.

Eric Galbraith, a professor in Earth System Science at McGill University and the senior author of the study, emphasized the need for fresh perspectives in addressing global challenges. He stated, “If we are to sustainably navigate climate change and biodiversity loss, adapt to rapid technological change, and achieve global development goals, it is crucial to understand the big picture of how the global human system functions, so that we can see where there is potential for change.”

The research aimed to provide a holistic, bird’s-eye view of our collective daily activities. William Fajzel, a Ph.D. student in Earth System Science at McGill University and the first author of the study, explained their objective: “We wanted to know – what does the time allocation of humanity look like, averaged over all people and across all countries? In other words, if the world were a single average person, what would their day look like?”

To answer this question, the research team analyzed time use and labor data spanning from 2000 to 2019, a period that excluded any impacts from the COVID-19 pandemic. They gathered data from over 140 countries, representing 87% of the world’s population.

The researchers categorized all the activities people engage in during their waking hours, encompassing both work-related and non-work-related activities. These activities were classified into 24 categories falling into three broad groups:

1. Activities intended to alter the external world, including tasks related to food, energy, construction, and environmental maintenance.
2. Activities focused directly on human minds or bodies, encompassing personal care, education, leisure, socializing, and more.
3. Organizing activities within society, such as transportation, trade, finance, law, and governance.

In their meticulous analysis, the team manually classified nearly 4,000 distinct activities, leading to some intriguing findings.

The most significant portion of our daily hours is devoted to activities centered around humans, totaling just over 9 hours. Additionally, sleep or being in bed accounts for another 9 hours, including the longer sleep patterns observed in youth. Of the remaining 6 hours, various tasks like food cultivation and preparation, commuting, and allocation-related duties (e.g., trade, finance, sales, law, governance, policing) each occupy approximately 1 hour. Astonishingly, waste management claims only 1 minute of our global day, a sharp contrast to the 45 minutes spent on cleaning and maintaining our living spaces. Furthermore, all construction and infrastructure-related activities take up just about 15 minutes.

Interestingly, the study found that the time allocated to activities like meals, daily travel, personal hygiene, and food preparation does not exhibit a systematic relationship with a population’s material wealth. In contrast, the time spent on food cultivation and collection displayed a strong correlation with economic status, varying from over 1 hour in low-income countries to less than 5 minutes in high-income countries.

Approximately one-tenth of the day is dedicated to economic activities. This includes both economic and non-economic activities. Within these categories, some of the total time represents individuals engaged in economic activities, such as doctors, nurses, cooks, and agricultural laborers.

The research team estimated that the entire global economy occupies approximately 2.6 hours of the average human day. Agriculture and livestock production dominate this economic activity, followed by allocational activities like trade, finance, law, and manufacturing. While this 2.6-hour figure may appear small, it equates to a 40-hour workweek for the two-thirds of the world’s working-age population (ages 15-64) that comprise the labor force.

These findings offer a unique perspective on the interplay between economic activities and the broader tapestry of human life on a global scale. They also suggest opportunities to reevaluate the allocation of time among specific activities, such as resource extraction, energy provisioning, and waste management, which currently require only around seven minutes of our daily lives.

India has officially concluded its lunar mission with the Pragyan rover, the pioneering craft that successfully reached the elusive lunar south pole. The Indian Space Research Organisation (ISRO) confirmed the rover’s transition into “Sleep mode” following its fruitful two-week assignment, equipped with charged batteries and an active receiver. ISRO expressed hope for a future reawakening for new tasks but also acknowledged the possibility of the rover remaining a perpetual lunar representative for India.

In a statement, ISRO stated, “Hoping for a successful awakening for another set of assignments! Else, it will forever stay there as India’s lunar ambassador.” This decision marks the end of a remarkable lunar endeavor that placed India alongside prestigious spacefaring nations like the United States, China, and the former Soviet Union. Furthermore, India achieved a significant milestone by venturing beyond these nations to reach the challenging lunar south pole, following the unfortunate crash of Russia’s Luna-25 during a similar attempt.

Chandrayaan-3, India’s lunar mission, achieved a remarkable and precise touchdown, a stark contrast to the earlier failed attempt in 2019. This achievement sparked jubilation across the nation, with the media lauding it as India’s most outstanding scientific accomplishment to date.

Pragyan, the rover, played a pivotal role in this mission by embarking on a journey of over 100 meters (330 feet) across the lunar surface. During its travels, it confirmed the presence of essential elements such as sulphur, iron, and oxygen on the moon, providing valuable insights into lunar composition and geology.

With the lunar mission’s success, India has set its sights on the sun, launching a probe on Saturday designed to study solar phenomena, particularly solar winds that can disrupt Earth’s magnetosphere and lead to the captivating auroras. ISRO has reported that the satellite is currently in good health and orbiting Earth as it prepares for its ambitious 1.5 million-kilometer (930,000-mile) journey towards the sun.

India’s lunar mission, encompassing the Pragyan rover and the Chandrayaan-3 spacecraft, has concluded after a productive two-week assignment.

Crucially, the Pragyan rover played a pivotal role in the mission’s success, embarking on an extensive journey covering over 100 meters (330 feet) across the lunar terrain. During its travels, Pragyan confirmed the presence of key elements such as sulphur, iron, and oxygen on the moon. These findings have provided invaluable insights into lunar composition and geology, enhancing our understanding of Earth’s celestial neighbor.

Having achieved success on the lunar front, India is now setting its sights on the sun, launching a probe designed to study solar phenomena, particularly solar winds that can disrupt Earth’s magnetosphere and give rise to the captivating auroras. ISRO has reported that the satellite is currently in a healthy state and is orbiting Earth as it prepares for its ambitious 1.5 million-kilometer (930,000-mile) journey towards the sun.

In summary, India’s lunar mission, highlighted by the Pragyan rover and the Chandrayaan-3 spacecraft, has officially concluded its lunar exploration phase after accomplishing a series of experiments over a two-week period. ISRO’s decision to transition the rover into “Sleep mode” marks the end of this remarkable lunar journey, while also holding the possibility of future reactivation for new missions. This achievement elevates India to the ranks of prestigious spacefaring nations, with the unique distinction of reaching the challenging lunar south pole. Moreover, the flawless landing of Chandrayaan-3 in contrast to the previous attempt in 2019 garnered widespread acclaim, establishing it as a landmark in India’s scientific endeavors.

The Pragyan rover’s extensive exploration of over 100 meters on the lunar surface confirmed the presence of essential elements, such as sulphur, iron, and oxygen, further enriching our knowledge of the moon’s composition and geology. Looking ahead, India’s space endeavors continue with a mission focused on the sun, aimed at studying solar winds and their impact on Earth, particularly the creation of auroras. ISRO has reported that the sun-studying satellite is in excellent condition and is poised to embark on its ambitious 1.5 million-kilometer journey toward the sun.

India’s first solar observation mission, Aditya-L1, is set to be launched by PSLV-C57 rocket from the spaceport on Sriharikota, an island off the southern state of Andhra Pradesh last week.

The development comes days after India became the first country to land a spacecraft close to the lunar south pole on August 23.

The sun is our nearest star and, therefore, can be studied in much more details compared to other stars.

Aditya-L1’s seven payloads are expected to provide crucial information to understand coronal heating, coronal mass ejection, pre-flare and flare activities and dynamics of space weather among other things.

The primary payload of Aditya-L1 will be sending 1,440 images per day to the ground station for analysis on reaching the intended orbit.

The spacecraft is scheduled to spend 125 days, travelling 1.5 million km to its destination. The solar mission will make India one of a small group of countries with probes studying the sun.

China has two such spacecraft orbiting Earth. Hinode, backed by space agencies from Japan, the UK, the US and Europe, is orbiting Earth and measures the magnetic fields of the sun.

Then there is the Solar & Heliospheric Observatory mission (SOHO), a joint project of NASA and the European Space Agency. The US has other solar missions, including the Parker Solar Probe, which in 2021 became the first spacecraft to pass through the sun’s corona, or upper atmosphere.

In the 6th century BC, Pythagoras, a renowned mathematician, unveiled his groundbreaking discovery that the square of the hypotenuse in a right-angled triangle equals the sum of the squares of its other sides. This revelation garnered immense acclaim, with the Greek colony of Croton declaring a 10-day celebration complete with a sumptuous feast. Pythagoras’s reputation as an academic superstar was solidified (“Pythagorean Theorem and its Reception: Ancient Greece’s Mathematical Triumph”).

In 8th century BC India, Baudhayana made a parallel revelation in his Sulba Sutra, establishing that the square formed by the “diagonal” of a triangle encompassed the combined area of squares formed by the triangle’s length and breadth. This concept mirrored the Pythagorean theorem, indicating its emergence even earlier in India (“Unveiling the Indian Origin of the Pythagorean Theorem”).

Advancing to Pythagoras’s era, his assertion that any number could be expressed as a perfect ratio of two natural numbers was challenged by a student, possibly Hippasus. Hippasus discovered that the square root of 2 could not be exactly expressed as a ratio, leading to a conundrum. Pythagoras, in order to preserve his theorem’s integrity, allegedly resorted to extreme measures, committing the chilling act of murdering Hippasus (“The Enigma of Hippasus and the Challenge to Pythagoras”).

Contrasting the peaceful academic climate in ancient India, Baudhayana and Aryabhata readily embraced irrational numbers, exemplified by approximations for the square root of 2 and “pi.” Unlike the Greeks, who struggled with arithmetic due to the absence of a place-value number system, these Indian mathematicians exhibited a more pragmatic approach (“Embracing Irrationality: Ancient Indian Mathematics”).

The absence of zero in the Greek mathematical framework posed difficulties in numerical calculations. Roman numerals, devoid of a place-value system, complicated arithmetic operations. Additionally, the Greeks were averse to the concept of zero, which they deemed a void, and they lacked negative numbers as these held no relevance in subtracting larger areas from smaller ones (“Zero’s Emergence and the Greek Numerical Dilemma”).

The 6th and 7th centuries AD marked a pivotal period for zero’s conceptual evolution, particularly with the mathematician Brahmagupta. While zero was used symbolically prior, Brahmagupta was the first to define zero as the remainder when subtracting a number from itself. This innovation facilitated the integration of zero into arithmetic and the establishment of the place-value decimal system. Brahmagupta also introduced negative numbers, endowing them with practical significance as “debts” (“Brahmagupta: Architect of the Concept of Zero”).

Brahmagupta’s seminal work, the Brahmasphutasiddhanta, penned in 628 AD, later reached the attention of Caliph al-Mansur of Baghdad through Indian scholar Kanka. This prompted an Arabic translation of the text, leading the Arabs to gradually embrace the concept of zero, which they termed “sifr” (“Zero’s Journey to the Arab World”).

Zero’s impact on Europe was delayed by 400 years until the Moors introduced it upon conquering Spain. While businesses embraced zero for balancing accounts, governments exhibited resistance; Florence even banned its use in 1299. The allure of zero persisted among merchants, who clandestinely employed a symbol to represent it despite the ban. The association of zero with secret codes gave rise to the term “cipher” (“Zero’s Assimilation in Europe: The Battle between Merchants and Governments”).

Ultimately, the enduring popularity of a number system is evident in the creation of secret codes to continue its use illicitly. Brahmagupta and Baudhayana, the architects of numerical concepts, may not have foreseen their profound influence. Regrettably, Baudhayana’s theorem is often attributed to Pythagoras, and Brahmagupta’s pivotal contributions to “Arabic numerals” remain relatively obscure (“Legacy of Mathematical Thought: Baudhayana, Brahmagupta, and the Evolution of Numbers”).

An unprecedented discovery in the realm of paleontology has unveiled a 300,000-year-old skull that challenges the known narrative of premodern human evolution. Recent research conducted by an international coalition of scholars from China, Spain, and the United Kingdom has brought to light a fossilized skull fragment, specifically the lower jawbone, in the Hualongdong area of eastern China in 2015. This fossil, along with 15 other specimens found at the same site, is believed to have originated during the late Middle Pleistocene era, a crucial juncture in the evolutionary trajectory of hominins, species closely related to humans.

The study, published on July 31 in the Journal of Human Evolution, illuminates the profoundly distinctive nature of the mandible, designated as HLD 6. It has defied conventional classification, perplexing researchers with its enigmatic attributes that defy existing taxonomic groups. This peculiarity is not an isolated occurrence among Chinese Pleistocene hominin remains; several others have eluded straightforward categorization, previously regarded as outliers. However, this recent revelation, coupled with other contemporaneous investigations, is steadily reshaping the understanding of evolutionary developments during the late Middle Pleistocene era.

HLD 6 and its Mosaic of Characteristics

Upon meticulous examination of the HLD 6 mandible, juxtaposed with those from Pleistocene hominins and modern humans, the research collective observed a fusion of features. Strikingly similar in shape to the mandible of Homo sapiens, the modern human species tracing its roots to Homo erectus, HLD 6 also exhibits a distinguishing trait akin to another branch stemming from Homo erectus: the Denisovans. A noticeable absence of a chin, a shared aspect with the Denisovans, is evident in HLD 6.

María Martinón-Torres, a co-author of the study and the director of the National Research Center on Human Evolution (CENIEH) in Spain, elucidated, “HLD 6 does not present a true chin but has some weakly expressed traits that seem to anticipate this typically H. sapiens feature.” This amalgamation of primitive attributes and those reminiscent of Homo sapiens distinguishes the Hualongdong population as the earliest known Asian fossil group to exhibit such a distinctive blend.

The postulation emerges that HLD 6 belongs to a class that remains unnamed, suggesting that hallmark characteristics of modern humans may have manifested as far back as 300,000 years ago, preceding the emergence of anatomically modern humans in eastern Asia. To account for potential variations between juvenile and adult skull structures, the researchers contemplated the age of the individual to whom the jawbone belonged.

HLD 6 is inferred to have been part of a 12- to 13-year-old individual. Although a comparable adult skull of the same species for comparison was unavailable, the team examined skulls from Middle and Late Pleistocene hominins of equivalent ages. Notably, the consistent patterns in cranial shapes across different ages provided further validation for their hypothesis.

Despite the insightful revelations gleaned from HLD 6, Martinón-Torres underscores the necessity for further investigation to definitively contextualize this find within the broader evolutionary framework.

In conclusion, an unparalleled archaeological revelation has been unveiled, carrying the potential to redefine the historical trajectory of human evolution. The unearthing of a 300,000-year-old mandible, referred to as HLD 6, in China’s Hualongdong region has stumped researchers due to its unprecedented amalgamation of traits that defy conventional classification. This discovery challenges prior assumptions about Pleistocene hominin fossils in China and compels a reconsideration of late Middle Pleistocene evolutionary patterns.

This groundbreaking study, featured in the Journal of Human Evolution on July 31, underscores the intriguing mixture of attributes within HLD 6’s mandible. Resonating with the shape of Homo sapiens’ mandibles while sharing the unique lack of a chin with the Denisovans, HLD 6 encapsulates a distinctive blend of characteristics that demarcates it as a novel entity. This mosaic of features presents a pioneering insight into the evolutionary development of early hominins in Asia, potentially indicating that recognizable modern human traits had emerged Religion300,000 years ago.

Nevertheless, the researchers acknowledge the complexity of their discovery and the necessity for additional investigations. In the absence of an adult skull of the same species for direct comparison, the team turned to comparable hominin skulls of varying ages, finding consistent patterns that reinforce their assertions. María Martinón-Torres, a lead researcher on the project, highlights the significance of continued research to holistically contextualize HLD 6 within the broader evolutionary narrative.

“More fossils and studies are necessary to understand their precise position in the human family tree,” she said.

A luminous symbol resembling a question mark, originating from the cosmos, has unexpectedly appeared in the background of NASA’s most recent imagery obtained through the James Webb Space Telescope. Experts are now speculating about the identity and nature of this enigmatic cosmic feature.

Unveiled on July 26, the initial near-infrared depiction portrayed a pair of fledgling stars denominated as Herbig-Haro 46/47. These stars are located within the Vela constellation of the Milky Way galaxy, situated at a distance of 1,470 light-years. These youthful stars are in an active phase of formation and are engaged in an intimate orbital dance around each other.

Although space and ground-based observatories have been scrutinizing these two stars since the 1950s, the extraordinary sensitivity of the Webb telescope has permitted the capture of the most intricate and high-resolution image to date. Distinguishing itself from its predecessors, the Webb telescope is designed to perceive the universe through longer wavelengths of light, offering a unique vantage point for exploration.

The James Webb Space Telescope serves as a beacon of insight into the origins of the cosmos. However, the presence of an enigmatic entity in the background of this image has sparked a multitude of questions, eclipsing the available answers. This cosmic question mark has yet to be subjected to meticulous observation and study, thus leaving scientists uncertain about its origin and composition.

Yet, grounded in the object’s form and position, scientists are constructing hypotheses. Matt Caplan, an assistant professor of physics at Illinois State University, noted, “The very first thing you can rule out is that it’s a star in the Milky Way… Stars always have these really big spikes… because stars are point-like.” This diffraction phenomenon, emanating from the mirror edges and camera supports, is a stark contrast to the anomaly’s structure. Caplan elaborated that the Webb telescope typically reveals six to eight stellar “prongs,” which unequivocally dismisses the possibility of it being a star.

Christopher Britt, an education and outreach scientist at the Space Telescope Science Institute, responsible for managing the Webb telescope’s scientific operations, posited the possibility of the object being a merger between two galaxies positioned billions of light-years away. This distance far surpasses the proximity of Herbig-Haro 46/47. According to Britt, the universe houses an array of galaxies beyond the confines of our own Milky Way, and their interactions, including collisions, lead to various configurations. These collisions can result in diverse shapes, even resembling a question mark.

While this specific entity’s appearance may be unprecedented, the amalgamation of galaxies into question mark-like configurations has manifested before. A contrasting variation of this form emerged from the Antennae Galaxies in the Corvus constellation. Moreover, most galaxies have undergone numerous interactions similar to this throughout their existence. However, these shapes are often transient, fleeting through cosmic time.

“The nature of space defies precise determination,” stated Caplan, underscoring the inherent complexity of cosmic movements. The Earth’s sun, partaking in its orbit around the galaxy, and the galaxy itself, composed of stars, experience gravitational forces tugging them in myriad directions. This ceaseless interplay underscores the dynamism of celestial mechanics.

This cosmic interplay is also the ultimate destiny for our own Milky Way galaxy, which will eventually merge with the Andromeda galaxy in approximately 4 billion years, as predicted by Britt. However, the precise configuration of this amalgamation remains uncertain.

Britt further hypothesized that the question mark shape might indicate a gravitational interaction between the two galaxies. “That hook of the question mark on the top looks a lot, to me, like what we call a tidal tail, where the stream of stars and gas has been kind of ripped off and has flown out into space,” he explained. To unravel the mysteries of this enigma, more data in the form of spectroscopic analyses is required, as emphasized by both Britt and Caplan. Such analyses could divulge essential details about the object’s distance and chemical composition.

“Nobody’s going to do this, though, because this is very much ‘a local man finds a chicken tender that looks like George Washington,’” Caplan said. “But there (are) observations you could make if you were motivated enough.”

“Dying Could Become Optional in 27 Years, Genetic Engineers Claim, as Immortality and Reversible Ageing Are on the Horizon”

During the book presentation of “The Death of Death” in Barcelona, two genetic engineers, José Luis Cordeiro and David Wood, made bold assertions about the future of human mortality and ageing. Cordeiro, hailing from Venezuela with Spanish roots and associated with the Massachusetts Institute of Technology (MIT) in the USA, and Wood, a mathematician from Cambridge (UK) and co-founder of the ‘Symbian’ operating system, firmly believe that dying may become optional within the next 27 years, and that ageing could become reversible.

Their book explores the possibility of achieving immortality through scientific means, and they assert that this milestone could come sooner than previously imagined. According to their predictions, by approximately the year 2045, humans would only die from accidents and never from natural causes or illnesses, given the advancements in medical science and genetic engineering.

A crucial aspect of their vision involves reclassifying old age as an “illness” to enable publicly-funded research aimed at finding a “cure” for ageing. They emphasize the significance of nanotechnology and other genetic manipulation techniques as central to the process. The proposed approach includes transforming detrimental genes into healthy ones, removing dead cells from the body, repairing damaged cells, implementing stem cell treatments, and even 3D printing vital organs.

At the core of the ageing process lies the shortening of DNA ‘tails,’ known as ‘telomeres,’ in chromosomes. In most cells (except red blood and sex cells), these chromosomes have 23 pairs, and as telomeres become progressively shorter, ageing occurs. Factors like exposure to toxins, such as smoking, alcohol, and air pollution, can accelerate this shortening process, leading to premature ageing.

Cordeiro and Wood’s research has led them to believe that within the next decade, diseases like cancer will become curable. Major corporations, including Google and Microsoft, are already expressing interest in medical breakthroughs related to ageing, with Microsoft setting up a cryopreservation center to investigate cancer’s potential complete eradication.

The engineers point out that the immortality they envision won’t necessarily lead to overpopulation concerns. They argue that the Earth still has ample space for more inhabitants, especially since modern societies tend to have fewer children than in the past.

Additionally, they predict that living in space will be a feasible option by that time, further expanding human habitation possibilities.

Addressing concerns about the cost of anti-ageing treatments, Cordeiro likens it to the initial high prices of smartphones, stating that the cost will gradually decrease as the technology becomes more accessible and widespread. They draw parallels with technological advancements, which initially tend to be costly and exclusive but eventually become democratic and affordable.

The engineers disclose that they have already been applying their techniques for two years, albeit illegally, in Colombia due to the country’s less stringent regulations regarding genetic manipulation. They highlight the case of Elisabeth Parrish, their first human patient, who sought their treatment after experiencing signs of ageing. Although the treatment is deemed risky and currently illegal, Parrish has not experienced any adverse side effects, and her blood’s telomere level has reportedly become “20 years younger than before.”

“I want Spain to have a place in the world of these technologies and show that we’re not mad, it’s just that people still don’t know about them,” Wood concluded.

Their book, “The Death of Death,” will be published in Spanish, English, Portuguese, and Korean, with all proceeds from sales reinvested into their research.

While their predictions may be met with skepticism, Cordeiro and Wood’s vision represents a bold and ambitious leap into the future of medical science and genetic engineering. Only time will tell if their optimism is justified and if humankind can indeed overcome the barriers of mortality and ageing through groundbreaking scientific innovations.

NASA’s Jet Propulsion Laboratory (JPL) has released a stunning postcard image of “Marker Band Valley” on Mars. The image shows two parts of the same day on the red planet; the panorama on the left is from 9.20 AM local Mars time whilst the one on the right is from 3.40 PM the same day. The image is a composite of two black and white panoramas taken by Curiosity’s navigation cameras. Additional colour was added to create a more artistic aesthetic, including blue for the part taken in the morning and red for the afternoon picture. The two images were taken to provide contrast to make the details stand out. The photo was taken on April 8, 2017 when the rover was in the foothills of Mount Sharp in the Gale Crater, an area it has been exploring since it landed in 2012.

The Marker Band Valley is a sulphate bearing region featuring unexpected signs of an ancient lake. From a distance, the valley is visible as well as two hills known as Bolivar and Deepdale. Curiosity engineer, Doug Ellison, said “capturing two times of day provides dark shadows because the lighting is coming in from the left and the right, like you might have on a stage – but instead of stage lights, we’re relying on the Sun.”

Although the two panoramas provide the main attraction, there are other features in the image. Since the camera was looking past the backside of the rover, parts of the rover itself is visible in the picture. There were three antennas and the rover’s nuclear power source, Radioisotope thermoelectric generator clearly visible. Additionally, the Radiations Assessment Detector in the image is designed to measure radiation levels on the planet. The data collected will be analyzed to determine how future astronauts can be protected from radiation during long-duration missions.

NASA’s Curiosity rover has been exploring Mars for more than five years, the longest duration of any Martian rover to date. Although Curiosity was not specifically designed to search for any indication of past or present life on the Red Planet, it is still an important mission. The data is critically important for understanding Mars and planning for future manned missions to the planet. Despite its longevity, Curiosity’s engineers are still discovering ways to explore and bring new information back to Earth.

As stated earlier, Curiosity’s target is to spend two Martian years exploring the Gale Crater area and then move to an area where there may be fresh mineral deposits. Meanwhile, NASA is preparing to send more rovers and drones to Mars to further investigate the Red Planet before manned missions are launched. With other space agencies such as SpaceX and Blue Origin also planning trips to Mars, the planet appears to be the next big endeavour of the space race.

In 1905, a package arrived at S Neumann & Co, a mining sales agency in London. The plain cardboard box was addressed to the agency and weighed just over a pound, but it carried cargo that was far from ordinary. Three months earlier, the surface manager of the Premier Mine in South Africa had been doing a routine inspection when he saw a reflected light in the rough wall above him. He thought it was a piece of glass that a colleague had placed there as a joke. Just in case, he took out his pocketknife to dig it out. Unfortunately, the knife snapped, and it took a lot of effort to remove the rock. Once it was removed, it turned out to be a monster of a diamond weighing 3,106.75 carats, almost the size of a fist. The Cullinan diamond, as it came to be known, was not just enormous but also unusually transparent.

After being polished and cleaved into several more manageable stones, the largest crystal it yielded would shine like the cool glow of a star in a distant galaxy, now known as the Great Star of Africa. The Cullinan diamond is the largest diamond ever found, known across the globe for its size and transparency. These characteristics were no accident. They were Clippir diamonds, a special category of the largest and clearest diamonds ever found, and they hold enigmatic stories of the Earth’s interior.

Today, the Cullinan diamonds are part of the British Crown Jewels, normally kept in the Tower of London and brought out for state events. The Cullinan I is in the Sovereign’s Sceptre, and the Imperial State Crown is embedded with its next-largest sibling, the Cullinan II. The less famous Cullinan III, IV, and V also featured in King Charles III’s coronation, placed on Camilla’s head during the ceremony on May 6th.

Before the rough diamond could take its place in history, however, it needed to be sold, which led to a significant concern: how do you transport such a valuable stone 7,926 miles (12,755km) without it being stolen? The precious rock was ultimately sent from Johannesburg by ordinary registered post for a mere three shillings, while a replica, placed conspicuously within the captain’s safe, was transported by steamboat to London, heavily guarded by police.

Clippir diamonds are fragments of the deep Earth, intriguing geological anomalies found disguised as mere jewellery. They are capsules from Earth’s mysterious realm of unfathomable pressures, swirling green rock, and elusive minerals far below the surface. Scientists worldwide have been studying them for decades to unlock the region’s secrets, and it’s the diamonds that we value most that are transforming our understanding of Earth’s interior.

The largest diamonds, like the Cullinan, have the most intriguing stories to tell. These special diamonds are stowaways from a world that we are rarely aware of, reaching the surface and providing clues about our planet’s otherwise inaccessible depths. These diamonds are unlike any other object that has made it out of the Earth’s interior without being changed to an unrecognizable extent.

The Cullinan diamond and other Clippir diamonds are captivating geological specimens. Their value is not just in their aesthetic appeal, but also in their tales about an enigmatic realm beyond our immediate experience. Clippir diamonds are transforming our understanding of Earth’s deep interior, and it’s a story that never fails to captivate the imagination of many.

Challenges in Diamond Research

Diamonds are some of the rarest and most valuable minerals on earth. They hold scientific value as well as commercial value, and researchers are always seeking new insights into their formation and characteristics. However, obtaining large, high-value diamonds for scientific research is no easy task. Even researchers who work regularly with diamonds find it difficult to acquire large specimens.

Maya Kopylova, a professor of mineral exploration at the University of British Columbia, acknowledges the challenges of obtaining diamond samples for research purposes. “Researchers have to have a good relationship with companies and they will never give you valuable samples,” she says. “So, they will never give us diamonds that are 6mm (0.2 inches) in size or larger.”

The obstacles to obtaining diamond samples are significant. Access to high-security facilities where diamonds are sorted is required, and identifying the specimens to be studied takes time and effort. Then comes the paperwork – all diamonds must travel with a Kimberley Process certificate, which proves their provenance and helps to prevent conflict or “blood” diamonds from entering the market.

Despite these challenges, Evan Smith, a research scientist at the Gemological Institute of America (GIA), has access to one of the largest collections of diamonds on the planet – millions of gems that have been sent there to be valued, so that they can be insured or sold. “Every few days, you might get to borrow a diamond for maybe a few hours, maybe a day or two and study it,” says Smith.

Smith and an international team of scientists requisitioned 53 of the largest, clearest, and most expensive diamonds available, including some from the same mine as the Cullinan diamond, one of the largest diamonds ever found. What they found was revolutionary. Nearly three-quarters of the diamonds contained tiny pockets, or “inclusions” of metal that had avoided rusting, while the remaining 15 contained a kind of garnet which only forms within the Earth’s mantle, the layer above its molten core.

Together, these inclusions provide a wealth of chemical clues that reveal how the diamonds were formed and under what conditions. These clues indicate that the diamonds could only have formed no fewer than 360km (224 miles) and no more than 750km (466 miles) below the earth’s surface. In this Goldilocks zone, it’s deep enough to explain the metal inclusions that hadn’t been exposed to oxygen, which is abundant higher up, and it’s not so deep that the garnet rocks would have broken down under the immense pressures of the lower mantle. Ordinary diamonds originate below the crust, just 150-200km (93-124 miles) down.

Smith’s latest research project involved examining a diamond worth almost as much as a small country – about the size of a walnut, with 124 carats of wonderous brilliance. Smith carefully stretched some rubber gloves over his fingers, peered into the microscope’s lenses, and examined the diamond for inclusions. Working with high-value diamonds is always a tricky business, but at GIA, Smith has access to the equipment, facilities, and expertise necessary to conduct cutting-edge research.

Together with Wuyi Wang, who is vice president of Research & Development at GIA, Smith analysed the 124-carat diamond and found that it formed at the deeper end of the possible range – at least 660km (410 miles) below the earth’s surface. Their findings have important implications for our understanding of the processes that shape our planet, as well as for the mining industry and the global economy.

From the depths

According to Evan Smith, “From a geological perspective, diamonds [in general] are really strange minerals.” Interestingly, humans invest millions of dollars every year in the search for diamonds, despite the destruction and chaos that often comes with the mining of these precious stones. The unusual properties of diamonds make them intriguing and valuable rocks. In fact, diamonds are unique in comparison to other rocks on Earth because they form at much deeper levels – up to 600 km below the surface. Even magma that reaches the surface comes from around 400 km down, but that is melted rock. Thus, diamonds that emerge on the surface are a significant composition of the Earth’s deeper layers.

Every diamond besides lab-grown ones that has ever been sold or worn is at least 990 million years old and crystallized during a time when there were only primitive algae on the planet, just starting to grow on land. Some diamonds are more ancient, originating from at least 3.2 billion years ago, when the planet was mostly water with no visible land or continents. After forming at such substantial depths, it takes an unusual series of events to bring diamonds to the Earth’s surface.

First, magma containing diamonds, developed over hundreds of millions of years of movement in the mantle, reaches closer to the surface as part of massive “plumes”. Next, it has to be in the right spot at the right time to be blasted to the surface. Then the diamond has to be in the right place at the right time, to be blasted up in magma. Finally, the diamond has to be located within kimberlite rock, where it is preserved for millions of years before being discovered.

In the last few decades, scientists began to notice that while most diamonds have a considerable amount of nitrogen, some larger diamonds contain much less. Typically, these are the Type II diamonds, which were exceptionally rare until discovered in large, high-quality diamonds like the Cullinan. “It’s not just that they’re big that sets them apart,” says Smith. “When you look at these big, high-quality [type II] diamonds, like the Cullinan, there turned out to be something strange about them that makes them more likely to fall into this category that should otherwise be something very rare. This was kinda a long-standing mystery.”

After studying some of these super-deep diamonds found at the Cullinan and Letseng mines in South Africa, researchers discovered that some diamonds had formed deeper in the Earth’s mantle than others. However, Smith’s team found a mineral in their 124-carat specimen that was discovered only six years ago – bridgmanite, the most abundant mineral on Earth that can only exist at the extreme pressures found in the lower mantle, the layer above the Earth’s molten core. Smith concludes that the sparkle of super-deep diamonds is due to the unusual formation process at extreme depths, which causes them to contain a unique mineral.

Despite these scientific insights, mining for diamonds remains a challenging and controversial activity. The pursuit of scientific knowledge must continue, but “the budget of any research project” is comparatively small in comparison to that of the diamond industry. Thus, although mining for diamonds and the geological properties of these stones coincide, ethical considerations need to be taken into account while harvesting these rocks.

Ancient carbon

The formation of the world’s largest and most valuable diamonds is a result of their unusual qualities, according to renowned diamond expert, Evan Smith. Regular diamonds are believed to start as a fluid, most likely ancient seawater trapped deep underground along with sinking oceanic plates. However, super-deep diamonds such as the Cullinan are formed from carbon dissolved within liquid metal, far down in the planet’s interior.

These vanished, subducting plates that are usually heavier, oceanic ones, eventually drift down into the lower mantle, but it has never been confirmed. Smith explains that super-deep diamonds provide important clues to confirm this phenomenon, as they may be composed of what these subducting plates are made of.

In addition to confirming what happens to oceanic plates that end up in our planet’s interior, super-deep diamonds can also reveal the kinds of things that may exist in the lower mantle. Carbon is a key component of these diamonds, but scientists have also discovered a rare super-deep diamond from Juína, Brazil, which contains a pocket of hydrous ringwoodite, a high-pressure form of olivine. Interestingly, this type of ringwoodite contains around 2.5% water and suggests that water is stored lower down in the mantle, where many super-deep diamonds form. Scientists have believed for years that all water on the Earth’s surface ultimately comes from the mantle; however, where it is stored has been up for debate considering olivine does not store water well.

Smith emphasizes that super-deep diamonds aren’t just extraordinarily valuable in monetary terms, but they also provide valuable scientific data about the Earth’s inner workings. “The more scientists learn about them, the clearer it becomes that super-deep diamonds aren’t just extraordinary valuable in monetary terms – without them, many of the processes inside the Earth would have remained hidden from view,” says Smith.

Furthermore, the rough form of diamonds can offer valuable insights into their formation. When diamonds emerge from the Earth, they’re lumpy and coarse, with none of the sparkle they acquire after they’ve been cut and polished. However, these lumps reveal a history of their adventures underground and may provide scientists with a chance to analyze diamonds in their natural state.

Super-deep diamonds offer valuable insights into the inner workings of the Earth. From confirming the process of subduction to understanding the storage of water in the mantle, these unusual diamonds have the potential to unlock a wealth of scientific data. As Evan Smith puts it, “There’s kind of a weird duality, where super-deep diamonds are both extraordinarily scientifically valuable, but also very commercially valuable.”

“The diamond can be chemically etched away by magma, and you end up with these really unusual shapes and intricate features… the natural surfaces that have been sculpted by all these different forces over millions of years. That is unique, and I see a lot of beauty in that.”

A group of scientists from MIT, Harvard University, Caltech and other institutions have made an extraordinary observation of a planet being engulfed by a star. For the first time, researchers have witnessed a star swallowing a planet, which provides crucial insight into how Earth will meet its end. The event observed was a hot Jupiter-size world that spiralled towards a dying star, approximately 1,000 times larger, until it was eventually ingested. This caused the star to grow rapidly and become over 100 times brighter in just 10 days, before gradually fading from view. The novel observation bolsters researchers’ understanding of what Earth’s finale is likely to be. Many astronomers believe that Earth will be subject to a similar fate billions of years down the line when the sun consumes its closest planetary neighbours.

Kishalay De, the lead author of the study and a postdoctoral student at MIT, commented that “all that we see around us, all the stuff that we’ve built around us, this will all be burned in a flash when the Sun decides to evolve and become puffy in 5 billion years”. This means that Earth, along with all of humanity’s creations, will disappear when the sun becomes a red dwarf.

Despite this pessimistic prediction, the researchers involved in the study are thrilled by their groundbreaking observation. The event witnessed allows us to gain a better understanding of the nature of celestial bodies and cosmological phenomena, improving our knowledge of the universe we inhabit. By being able to witness and understand this event, scientists can further their knowledge of how galaxies form and develop over time.

“Wow! That is my first reaction,” Amanda Karakas, an astrophysicist at Monash University in Australia who was not involved in the study, said in an email. “It certainly provides clues as to what will happen to the planets in our solar system and the Earth, many years from now.”

A Star Engulfed a Planet: Discovery by Accident

A team of astrophysicists from the California Institute of Technology have discovered that a star in the Milky Way galaxy, 12,000 light years away in the Aquila constellation, recently consumed a Jupiter-sized planet. The team was initially analyzing data in search of eruptions of binary star systems, in which two stars orbit each other and one brightens as it pulls mass from the other.

However, they noticed that one star became far brighter over roughly a week. When the researchers investigated its chemical composition using observations from the Keck Observatory in Hawaii, they found it was surrounded by molecules that can only exist at cold temperatures. After taking infrared observations nearly a year later, the team discovered the star was still shining brightly in the infrared bands of light, even though it was no longer visible to the naked eye, which suggests the star was brightening as a result of merging with something else. This led the team to estimate the total amount of energy released by the star to be 1,000 times smaller than past observations of stars merging with one another, leading Dr. De, a Caltech investigator, to declare “what you have is the star that engulfed the planet.”

The team also suggested that planet engulfments are in fact quite common, though hard to spot, because they are usually much less pronounced than big flares that emanate from stars caused by other violent events such as binary mergers. The infrared data has illuminated these processes, previously obscured by brighter eruptions. Co-author Mansi Kasliwal stated that when “it’s just a planet merging into a star, it’s intrinsically very weak, so it’s harder to find them…When something is harder to find, all we need is a more powerful camera.”

This theory was then put to the test by other members of the team who modelled the observations and reconstructed what may be happening. The team hypothesised that the initial bright flash was the final moments of the planet getting eaten by the star, which led to a blast of the star’s outer layers. This then settled as cold dust over the following year, which accounts for the leftover dust also observed.

While it is challenging to detect these events, researchers are growing increasingly skilled at observing them with updated technology. As this continues to develop, scientists foresee the discovery of many more similar events on a much larger scale. For instance, Dr. Anna Ho, other Caltech astronomer, suggested that a recently discovered dimming star could have been caused by the merger of a smaller star or planet with a much larger one.

Dr. Emily Levesque, an astronomer at the University of Washington, echoed this sentiment, stating that this discovery is “interesting and exciting” for the field. She went on to say that the “idea of planets falling into their stars is not that new…. [Planet engulfment is] something that we do expect to happen, but we don’t know that much about the occurrences … [That is] why getting any observational handle on the candidates is really important for our theoretical understanding and modeling of what’s going on.” The sheer amount of observational data that astrophysicists have access to continues to grow, and this is paving the way for more discoveries of this kind in the years ahead.

Reading is the art of listening to words. It is listening to words written on paper, a mobile screen, boards, or sounds while speaking. Decoding each word creates its own world to explore and experience. People have different opinions on the topic of reading. Each individual perceives it to be different from one another. For some, it is a gateway to imagination and creativity; for others, it is a form of escapism; for others, it is a means for developing a skill, while for a few, it is a space for introspection and growth. The words on the page come to life as we visualize the characters, settings, and events described by the author.

Here are some stories from strangers about their experience with reading:

“Reading for me is formally for the purpose of education and language,” said one person. Reading is a forced experience in life, where one is forced to read to understand topics and learn. It is a must-do for the purpose of education. but moving forward, the word reading took a different shape of its own in different minds.”

“Reading fantasy gives me a lot to imagine, a lot more to think on, and a lot more to vent my energy on,” said Amit, another colleague, whom I interviewed for this story. Fantasy was the genre that was preferred by most people during the course of interviews.

The opportunity to think beyond the boundaries of the present world and to imagine a world with magic, chants, and spells has its own unimaginable pleasure for the minds of readers. At a young age, Amit started his reading journey with J.K. Rowling’s ‘Harry Potter,’ which later moved on to Rick Riordan’s ‘Percy Jackson.’

Amit shared about how much of an obsessive reader he was of Harry Potter. The set of books he would never let go of, even in the midst of exams and work.

Rose talked about Leigh Bardugo’s ‘Six of Crows and Sarah J. Mass’s ‘A Court of Thorns and Roses.’ The feeling of transportation to different realms, immersed in rich, vivid imagery ignites the worlds of imagination. This is how she explained reading a book about an unknown world.

Young adult stories, which are later adapted into movies, are the next thing on the list that people prefer. John Green’s ‘The Fault in Our Stars,’ Stephen Chbosky’s ‘The Perks of Being a Wallflower,’ Jennifer Niven’s ‘All the Bright Places,’ and Five Feet Apart’ have topped the list.

When asked as to what they preferred, the movie or the book, most of them picked the movie, while a few chose the book. But the intriguing part of the question was formed when one replied, “I prefer both movies and the book; often I prefer to read the book first, then watch the movie, and later revisit the book again with the revealed images of the characters.”

Sometimes getting a face to imagine and relate the story gives way to incredible fan art.

There are many different reading genres that one can explore and enjoy. A few examples are non-fiction, literary fiction, mystery or thriller, romance, science fiction, historical fiction, young adult, contemporary fiction, horror, biographies, and autobiographies.

To conclude, one can safely say that reading is a form of art that profoundly affects people’s brains, hearts, and souls. It is seen as a skill that many people nurture and celebrate, adding worth and enhancing one’s own life and the one’s world of imagination.

A strong memory is essential to maintaining a healthy and productive lifestyle. Neuroscientists at MIT Sloan have discovered two simple exercises to boost both working and long-term memory. These exercises can be done daily to improve memory.

1. Chunking: Strengthen your working memory

The first exercise is chunking, breaking down long or complex pieces of information into smaller chunks. A phone number like “3-3-2-1-6-7,” can be divided into “33,” “21,” and “67” and given a special meaning. Chunking is also useful for presentations where lengthy talks can be divided into key points with a list of catchphrases to remember them.

2. Space repetition: Strengthen your long-term memory

The second exercise is space repetition, which focuses on memory retention over longer intervals. After learning a fact, it should be repeated out loud a few times, then again after a few hours, days, and weeks. If needed, start the process again to reinforce the memory.

In addition to memory exercises, a healthy lifestyle can also contribute to improved cognitive function. Exercise plays an important role, with cognitive decline being almost twice as common among adults who are inactive. The Centers for Disease Control and Prevention recommends at least 150 minutes a week of moderate-intensity physical activity or 75 minutes of vigorous-intensity activity for adults.

A healthy diet is also essential for cognitive function with a colourful variety of vegetables and plants being recommended. Darker vegetables such as kale and eggplants are particularly beneficial, as are foods containing high levels of polyphenols, such as coffee and dark chocolate in moderation.

Clearing headspace can help reduce information overload. Taking time to think about what is important and what is easily recalled can enable intentional changes to be made in daily life, leading to a reduction in forgetfulness.

According to MIT Sloan neuroscientist, “Chunking and space repetition are two easy exercises that can be done daily to improve the memory strength of an individual especially to help to ward off memory issues later on. Any mentally stimulating activity will boost your brainpower, but it is important to have plenty of exercise, a healthy diet and clear up headspace on regular basis”, she added.

Humans will be able to upload consciousness and sensibility in computers by the end of 2023, claims an Indian-origin computer scientist.

Dr Pratik Desai has asked people to start recording their loved ones’ voices, which will “live” even after their death.

In other words, users can create a computerised avatar that resembles their loved one before their death, which can live forever on their screens.

“Start regularly recording your parents, elders and loved ones,” Desai recently wrote on Twitter.

“With enough transcript data, new voice synthesis and video models, there is a 100 per cent chance that they will live with you forever after leaving physical body.

“This should be even possible by end of the year,” he noted.

Desai is not the only one who has claimed this.

Previously, metaverse company Somnium Space offered an AI-based “live forever” mode. It aims to allow individuals to talk with their loved ones in the metaverse.

In an interview with Motherboard, the company’s founder and CEO Artur Sychov said his project will allow people to store the way they talk, move, and sound until after they die, when they can come back from the dead as an online avatar to speak with their relatives.

“Literally, if I die — and I have this data collected — people can come or my kids, they can come in, and they can have a conversation with my avatar, with my movements, with my voice,” Sychov was quoted as saying to Vice.

“You will meet the person. And you would maybe for the first 10 minutes while talking to that person, you would not know that it’s actually AI. That’s the goal,” he added.

Another US-based company Deepbrain has also developed a programme called “Re;memory” which allows users the opportunity to walk down a memorial hall dedicated to a late loved one and even interact with the person “through an actual conversation”. (IANS)
