<p>If you like to indulge in lobsters, shrimp, tuna, and other seafood then you need to be more careful. According to a recent study, there can be potential downsides to eating seafood.

<p>The study noted that while guidelines for safe seafood consumption exist for mercury and other contaminants it doesn't exist for "forever chemicals". "Our recommendation isn't to eat seafood -- seafood is a great source of lean protein and omega fatty acids.

NASA's Webb Telescope found margarita, vinegar-like chemicals on protostar

<p>Jupiter, the solar system's largest planet, hasn't received as much attention from astronomers as Mars. The reason is clear: Mars is viewed as the prime candidate for human colonisation. While Jupiter isn't on that list, though its moon Europa might be in the future.</p>

<p>However, because Jupiter is crucial for the entire solar system, there are plans, like the Europa Clipper mission, to study it more extensively.</p>

<p>This will help answer questions about its role and composition. It's essential to remember that Jupiter is often seen as a failed star. If it had gathered more material, it might have become one. Also, Jupiter has numerous moons, including Europa, which are gaining importance.</p>

<p>However, NASA has now announced its plans for Jupiter. The Europa Clipper mission, which began in 2013 and was officially confirmed in 2019, will soon head towards the planet.</p>

<h2><strong>Travel duration</strong></h2>

Jupiter, the solar system's largest planet, hasn't received as much attention from astronomers as Mars. The reason is clear: Mars is viewed as the prime candidate for human colonisation.

Jupiter, the solar system's largest planet, hasn't received as much attention from astronomers as Mars. The reason is clear: Mars is viewed as the prime candidate for human colonisation. While Jupiter isn't on that list, though its moon Europa might be in the future. However, because Jupiter is crucial for the entire solar system, there are plans, like the Europa Clipper mission, to study it more extensively. This will help answer questions about its role and composition. It's essential to remember that Jupiter is often seen as a failed star. If it had gathered more material, it might have become one. Also, Jupiter has numerous moons, including Europa, which are gaining importance. However, NASA has now announced its plans for Jupiter. The Europa Clipper mission, which began in 2013 and was officially confirmed in 2019, will soon head towards the planet.

Exploring Jupiter: All about NASA’s Europa Clipper mission

<p>A clinical trial has revealed that stem cells taken from body fat can help restore movement in patients affected by paralysis and can improve sensation. A small trial at Mayo Clinic, a nonprofit American academic medical centre, has shed light on the potential benefit of stem cells and regenerative medicine. Thanks to stem cell therapy, a patient who was paralysed from the neck down following an accident was able to walk again.</p>

<p>The first author of the study, Mohamad Bydon, MD, a Mayo Clinic neurosurgeon, said in a press release, "This study documents the safety and potential benefit of stem cells and regenerative medicine." "In spinal cord injury, even a mild improvement can make a significant difference in that patient's quality of life," he said.</p>

<h2><strong>How was the study conducted?</strong></h2>

<p>The phase 1 study involved 10 patients who got their stem cells removed from their abdomen or thigh. Following this, millions of new mesenchymal stem cells (MSCs) were grown in the lab over the next several weeks. These cells were then injected into each patient’s lumbar spine.</p>

<p>Your eyes can reveal a lot about your brain health. According to new research, changes in one's visual sensitivity can indicate signs of dementia around 12 years earlier than the official diagnosis.</p>

<h2><strong>How did the researchers conduct this study?</strong></h2>

<p>Researchers followed 8,623 healthy individuals in Norfolk, England, for several years. Among them, 537 developed dementia. By analysing the data from the study, researchers identified factors that might precede a dementia diagnosis.</p>

<h2><strong>The visual sensitivity test</strong></h2>

<p>Researchers gave the participants a visual sensitivity test at the start of the study. The test required them to identify a triangle among moving dots. The ones who were slower to spot the triangle later developed dementia.</p>

<h2><strong>Visual signs of dementia</strong></h2>

<ul>
	<li>Visual issues could be a warning sign of cognitive decline. Alzheimer's disease first affects areas of the brain linked to vision before damaging memory-related regions, according to studies. Thus, vision tests could detect signs of memory disorders.&nbsp;</li>
	<li>Alzheimer's also affects contrast sensitivity and the ability to discern colours may be impacted early on. These impairments can affect daily life without immediate awareness.</li>
	<li>One early sign of Alzheimer's is difficulty in controlling eye movements, especially in ignoring distracting stimuli. This issue might increase the risk of accidents, particularly while driving.</li>
	<li>People with dementia may struggle to process new faces efficiently. They may not follow the usual pattern of scanning a person's face during conversation, making them seem distant or lost.</li>
</ul>

<h2><strong>Eye movement could help improve memory</strong></h2>

<p>Studies suggest that eye movement might enhance memory performance. Watching TV or reading, activities involving frequent eye movements could potentially lower the risk of dementia.</p>

<h2><strong>What are some limitations of this study?</strong></h2>

<p>Despite promising findings, using eye movements as a diagnostic tool for Alzheimer's faces challenges. Access to expensive and complex eye-tracking technologies remains a barrier. Until more accessible options are available, widespread use of eye movements in diagnosis remains limited.</p>

<p>Hospitals have a distinct smell because of the cleaning practices used to prevent infections. It has been a common belief that infections contracted during hospital stays were because of the bacteria acquired in the hospitals. New research, however, denies the theory and reveals that the reason behind the hospital infections is the bacteria that are already present in or on the bodies of the patients before they reach them.</p>

<p>The research published in Science Translational Medicine compared the bacteria that reside on and inside our bodies to the ones that cause healthcare-associated infections and found that most of the time the harmless bacteria that coexist with us when we are healthy cause serious infections when we are in hospitals.</p>

<h2><strong>Why are surgical site infections so problematic?</strong></h2>

<p>Surgical site infections are a major concern in healthcare settings. They not only add significantly to the annual expense of hospital-acquired infections, but they also raise the risk of hospital readmission and death after surgery. Despite considerable preventive efforts implemented by hospitals, surgical site infections have not decreased, accounting for around one in every thirty procedures.</p>

<h2><strong>How and why do surgical infections occur in patients?</strong></h2>

<p>To understand the reason behind surgical site infections, they conducted a study involving over 200 patients undergoing spinal surgery. They analysed bacteria from the patients' noses, skin, and stool before surgery and monitored them post-surgery.</p>

<p>The findings revealed that 86 percent of bacteria causing infections after spine surgery were genetically matched to bacteria already present in the patients before surgery. Furthermore, nearly 60 percent of these infections displayed resistance to antibiotics administered during surgery or used as antiseptics before incision.&nbsp;</p>

<h2><strong>How can this study help improve future cases of surgical infections?</strong></h2>

<p>Understanding that patients' microbiomes play a significant role in surgical site infections offers a potential pathway for improved prevention strategies.

<p>Archaeologists have discovered evidence of ancient Stone Age rituals. The analysis of bones discovered in a tomb in France's Rhone Valley uncovers evidence of ritualistic killings reaching back over 2,000 years. These findings, which were published in Science Advances on April 10, give insight into our predecessors' activities.</p>

<p>The tomb, located in Saint-Paul-Trois-Chateaux in Avignon in southern France, was discovered more than two decades ago. The tomb, which resembled the structure of a grain silo, held the bones of three women who were interred around 5,500 years ago.</p>

<h2><strong>What is incaprettamento?</strong></h2>

<p>What distinguishes this find is the women's sad fate. According to analysis, they were buried alive, demonstrating the&nbsp;traditions of the time.

<p>Looking directly at the sun during a solar eclipse can cause serious damage to eyes. Staring at the sun can damage the retina and also result in permanent vision loss or impairment.</p>

<p>To safely view a solar eclipse, one must always use proper eye protection, such as solar viewing glasses that are specifically designed for this purpose. These glasses have special filters that block out harmful ultraviolet and infrared radiation and allow one to safely observe the eclipse.&nbsp;</p>

<p>However, on the day of the total solar eclipse on April 8, many did not take any precautionary measures in New York City, as per reports.&nbsp;Reports of eye-related issues soared at a medical facility in New York City. Search of individuals seeking information online about experiencing eye discomfort also soared.</p>

‘I don’t want to go blind’: People scared of eye injuries post solar eclipse

<p>All of us go through ups and downs in our lives. Some negative experiences, illnesses, injuries and breakups might even have long-term effects on our behaviour and thought process. But is there any way to neutralise past negative experiences and turn them into meaningful life lessons so that they could have a positive effect on our future decisions?&nbsp; A new research published by VanEpps and Truncellito in Current Opinion in Psychology has revealed two methods through which individuals can be prepared to view past negative events through a positive lens.</p>

<h2><strong>First method: Cognitive reappraisal</strong></h2>

<p>One way to do this is to completely reframe the negative event and put more emphasis on the positive aspect. Known as ‘Cognitive Reappraisal,’ the method involves rewriting the past event and changing your assumptions and interpretations.</p>

<p>For example, if you went through a heart-breaking break-up with your partner and you believe you might never recover from that.</p>

<p><strong>Watch:&nbsp;New evidence suggests size of the Sun could be smaller, says report</strong></p>

</div>
<a class="close-mark close-div" href="#" id="jqclosemark">×</a></div>

<p>Through cognitive reappraisal, you would get the opportunity to learn more about the positive aspects of your negative event. In this case, more emphasis can be placed on aspects like self-discovery, growth, and a more committed and fulfilling romantic relationship in the future.</p>

<p>This is the first way to reduce the negative emotional impact of a stressful past event.</p>

<h2><strong>Second method: Redeeming the past with storytelling</strong></h2>

<p>The other method to neutralise a negative past event is through the art of storytelling. This method involves repackaging the unfavourable experiences and “redeem the past.”</p>

All of us go through ups and downs in our lives. Some negative experiences, illnesses, injuries and breakups might even have long-term effects on our behaviour and thought process.

All of us go through ups and downs in our lives. Some negative experiences, illnesses, injuries and breakups might even have long-term effects on our behaviour and thought process. But is there any way to neutralise past negative experiences and turn them into meaningful life lessons so that they could have a positive effect on our future decisions? A new research published by VanEpps and Truncellito in Current Opinion in Psychology has revealed two methods through which individuals can be prepared to view past negative events through a positive lens. First method: Cognitive reappraisal One way to do this is to completely reframe the negative event and put more emphasis on the positive aspect. Known as ‘Cognitive Reappraisal,’ the method involves rewriting the past event and changing your assumptions and interpretations. For example, if you went through a heart-breaking break-up with your partner and you believe you might never recover from that. Watch: New evidence suggests size of the Sun could be smaller, says report × Through cognitive reappraisal, you would get the opportunity to learn more about the positive aspects of your negative event. In this case, more emphasis can be placed on aspects like self-discovery, growth, and a more committed and fulfilling romantic relationship in the future. This is the first way to reduce the negative emotional impact of a stressful past event. Second method: Redeeming the past with storytelling The other method to neutralise a negative past event is through the art of storytelling. This method involves repackaging the unfavourable experiences and “redeem the past.” Well, if you incorporate your negative events in a wider story, it can help you build a larger, more positive narrative overall. After all, not all stories are pleasant, without pain and embarrassment. But all of them carry a great story-telling value. A good story involves tension and conflicts.

Scientists discover two great techniques to overcome past negative events

<p>Venus is often referred to as Earth's "sister planet" because of their similar size and composition, but they have some differences. Earth has abundant liquid water on its surface while Venus does not. This is because Venus is leaking.&nbsp;</p>

<p>The surface temperature on Venus is extremely high, reaching about 900 degrees Fahrenheit (about 475 degrees Celsius). It has a thick atmosphere of carbon dioxide and other gases which makes it impossible for liquid water to exist.</p>

<p>However, there is evidence to suggest that Venus may have had liquid water in its distant past.</p>

<p>New findings from the 2021 BepiColombo mission, a joint mission between the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA) with the goal of exploring the planet Mercury, revealed that gases, including oxygen, are escaping from Venus's upper atmosphere. Published in the Nature Astronomy journal, the study underscored the importance of understanding Venus's atmospheric evolution.</p>

<p>Venus lacks a strong magnetic field like Earth's. Its upper atmosphere is exposed to the solar wind and a stream of charged particles emitted by the Sun.&nbsp;</p>

<p>This interaction between the solar wind and the upper atmosphere of Venus can lead to the escape of ions, particularly hydrogen and oxygen ions, into space. These ions are stripped away from the planet's atmosphere by the solar wind.</p>

<p>On Wednesday (April 10), Arizona's top court revived a Civil War-era law from 1864, which puts a near-total ban on abortion. The law makes it a felony to provide an abortion or help a person obtain one.</p>

<p>According to a new paper in the journal JAMA Health Forum, adults are seeking permanent contraception after the US Supreme Court overturned Roe V. Wade in 2022 and took away the 'constitutional' right to abortion. Since then, more and more US states have completely banned abortions with others imposing limited access on abortions.</p>

<p>The study analysed data from 113 million people across the United States and found that there's been an increase in permanent contraception in both men and women between the ages of 18–30.</p>

<h2>Women's permanent contraception rate double then men</h2>

<p>Women undergoing tubal ligations, known as 'getting your tubes tied' were twice as high as men undergoing vasectomies,</p>

<p>Since Roe v. Wade was overturned in 2022, there has been an immediate&nbsp;rise of 58 sterilization procedures for women, or around 5.31 procedures per 100,000 persons each month. This is roughly double the previous rate of 2.84 procedures&nbsp;per month for women. Men had an overall increase of 27 procedures, but no significant increase in monthly procedures.</p>

<p>“The major difference in patterns of these two procedures likely reflects the fact that young women are overwhelmingly responsible for preventing pregnancy and disproportionately experience the health, social, and economic consequences of abortion bans,” lead author Jacqueline Ellison, said in a press release.</p>

<p>“Women and people who can get pregnant also disproportionately experience the health, social, and economic effects of unwanted pregnancy. Because of this and the fact that parenting responsibilities fall predominately on women, cisgender men may not feel the same sense of urgency to undergo permanent contraception,” Ellison added.</p>

<h2><strong>What do these findings imply?</strong></h2>

<p>The abrupt increase in permanent contraceptive methods shows fear or anxiety among young people with restricted abortion access. “What is concerning to me is that young people may be feeling pressure to use a contraceptive method that they otherwise would not prefer, which has implications for reproductive autonomy,” Ellison said.</p>

<p>An extraordinary surge of intense radiation took place across the solar system on October 9, 2022.&nbsp;This unprecedented phenomenon was promptly dubbed as BOAT (the Brightest of All Time) by astronomers and it captured immediate attention. The origin of this phenomenon was identified as a gamma-ray burst (GRB) and it is the most powerful category of explosions known in the universe. Now, a shocking discovery has come to the fore - no gold or platinum was formed by this brightest supernova.&nbsp;</p>

<p>After a meticulous analysis of the gathered data, astronomers have gained a deeper understanding of its profound scientific implications. They have revealed astonishing findings regarding this monumental cosmic event, the collapse of a massive star.</p>

<p>This burst of light, dubbed GRB 221009A, occurred over two billion light-years away and momentarily dazzled space instruments.&nbsp;A recent analysis using the data from NASA's James Webb Space Telescope (JWST) shows what could be the event's origin. Contrary to expectations, the researchers found no traces of precious metals like platinum and gold, typically associated with supernovas.</p>

<h2><strong>Collapse of a massive star&nbsp;</strong></h2>

<p>Dr. Peter Blanchard, leading the study, expressed surprise, stating, “When we confirmed that the GRB was generated by the collapse of a massive star, that gave us the opportunity to test a hypothesis for how some of the heaviest elements in the universe are formed."</p>

<p>The absence of these heavy elements challenges existing theories about their formation and is now triggering further inquiry into the cosmic processes at play.</p>

<p>“We did not see signatures of these heavy elements, suggesting that extremely energetic GRBs like the Boat do not produce these elements. That doesn’t mean that all GRBs do not produce them, but it’s a key piece of information as we continue to understand where these heavy elements come from. Future observations with JWST will determine if the Boat’s ‘normal’ cousins produce these elements,"&nbsp;Blanchard said.&nbsp;</p>

They have revealed astonishing findings regarding this monumental cosmic event, the collapse of a massive star. This burst of light, dubbed GRB 221009A, occurred over two billion light-years away and momentarily dazzled space instruments. A recent analysis using the data from NASA's James Webb Space Telescope (JWST) shows what could be the event's origin. Contrary to expectations, the researchers found no traces of precious metals like platinum and gold, typically associated with supernovas. Collapse of a massive star Dr. Peter Blanchard, leading the study, expressed surprise, stating, “When we confirmed that the GRB was generated by the collapse of a massive star, that gave us the opportunity to test a hypothesis for how some of the heaviest elements in the universe are formed."

Indian-origin professor who led NASA mission during solar eclipse The absence of these heavy elements challenges existing theories about their formation and is now triggering further inquiry into the cosmic processes at play. “We did not see signatures of these heavy elements, suggesting that extremely energetic GRBs like the Boat do not produce these elements. That doesn’t mean that all GRBs do not produce them, but it’s a key piece of information as we continue to understand where these heavy elements come from. Future observations with JWST will determine if the Boat’s ‘normal’ cousins produce these elements," Blanchard said.

Leading an investigation involving around 7,000 GRBs, primarily detected by NASA's Fermi Gamma-ray Space Telescope and the Russian Konus instrument on NASA's Wind spacecraft, Eric Burns, an assistant professor of physics and astronomy at Louisiana State University in Baton Rouge, sought to determine the frequency of such exceptionally bright events. Their findings indicated that occurrences of this magnitude happen nearly once every 10,000 years. (With inputs from agencies)

Shocking revelation! No Gold and Platinum formed by brightest supernova

<p>Neuroscientists have discovered that the spinal cord can make its memories independent of the brain. This new revelation can be a game-changer for treating patients' spinal cord injuries.</p>

<p>Earlier studies have shown that the spinal cord can initiate reflex movements without the brain's involvement and it appears to learn and adjust movements based on previous experiences. The mechanism behind this has been unknown.&nbsp;</p>

<p>"Learning and memory is often attributed as functions of the brain exclusively. Although scientists knew for more than a century that the spinal cord could learn and adapt movements in the absence of brain input, we did not know how the spinal cord learns and memorises what is has learned," Aya Takeoka, the author of the study, told Newsweek.&nbsp;</p>

<p>"Gaining insights into the underlying mechanism is essential if we want to understand the foundations of movement automaticity in healthy people and use this knowledge to improve recovery after spinal cord injury," she added.</p>

<p>Next, they tried to find the neuronal circuitry that was helping the spinal cord to store memory. They discovered that the spinal cord does not need&nbsp;learning cells or&nbsp;memory cells for&nbsp;recalling and learning what it has experienced.</p>

<p>Researchers have found unusual carvings on Peruvian rocks that might have been created by ancient humans who here high. The carvings are located in Toro Muertoin a Peruvian desert valley dubbed as the Majes River Valley. The valley is home to over 2,500 volcanic boulders which are carved with ancient inscriptions.</p>

<p>These inscriptions or petroglyphs might have been carved by&nbsp;hallucinating ancient artists according to the research published in the&nbsp;Cambridge Archaeological Journal.</p>

<p>The archaeologists from Poland's Adam Mickiewicz University and the University of Warsaw who conducted the study found a characteristic feature in the Toro Muertoin's petroglyph iconography that is human figures engaged in dance, referred to as&nbsp;danzantes,&nbsp;often&nbsp;accompanied by geometric patterns, predominantly variations of zigzag lines.</p>

<p><strong>The researchers have multiple theories for what these lines could represent:</strong></p>

<h2><strong>Songs or wild dancing</strong></h2>

<p>"We suggest that zigzag lines could be representations of songs, which seems particularly intriguing given the repeated juxtaposition of these patterns with the figures of dancers at Toro Muerto, not only in the more complex compositions (Figs 4–8) but also in the less complex as well," the paper read.</p>

<h2><strong>Visual metaphors for passage to the afterlife</strong></h2>

<p>It is also speculated that some complex arrangements of danzantes and linear geometric patterns might serve as visual representations of transitioning to the afterlife.</p>

<p>"Our interpretation suggests that the banded structures of geometric patterns could be representations of the cosmos—its spheres and events connected to its creation and its exploration, which could have come about during ritual ceremonies of which dance and song were the quintessence," researchers said. "The associations of danzantes with banded structures of patterns might embody visualization of being in this parallel world, emphasizing its authenticity and invariability," they added.</p>

<p>New research by a team of scientists from Kyushu University in Japan has discovered that baby stars also 'sneeze'. Their powerful sneeze launches gas, dust, and magnetic energy into space.</p>

<p>These 'sneezes' or eruptions by baby stars or 'protostars' are an important part of their development, and can reveal a lot about the star. Scientists may also be able to determine whether the star will be surrounded by planets in future or not.</p>

<p>The Atacama Large Millimeter/submillimeter Array (ALMA) was used by the researchers to explore the gas and dust disks that surround baby stars which collapse to give birth to planets. These disks are called "protostellar disks."</p>

<h2><strong>Why do baby star sneeze?</strong></h2>

<p>When dense and cool patches of material gather in massive clouds of interstellar gas and dust, known as stellar nurseries, they gain mass and collapse to give a star to the cosmos. Every protostar is surrounded by a protostellar disk of matter.</p>

<p>"These structures are perpetually penetrated by magnetic fields, which brings with it magnetic flux. However, if all this magnetic flux were retained as the star developed, it would generate magnetic fields many orders of magnitude stronger than those observed in any known protostar," team leader and Kyushu University scientist Kazui Tokada said in a statement.</p>

<p>The research published in the Astrophysical Journal discovered that 'sneezing' is a mechanism during star development to&nbsp;remove that magnetic flux. Earlier, researchers believed that the magnetic field gradually weakened over time and there was no separate mechanism for it.</p>

<h2><strong>How did the researchers discover stars 'sneezing'?</strong></h2>

<p>The team observed MC 27, a stellar nursery located approximately 450 light-years from Earth, using the ALMA array, a collection of 66 high-precision radio telescopes constructed 5,000 metres above sea level in northern Chile.</p>

<p>"As we analysed our data, we found something quite unexpected. There were these 'spike-like' structures extending a few astronomical units from the protostellar disk. As we dug in deeper, we found that these were spikes of expelled magnetic flux, dust, and gas," Kazui Tokada added.</p>

<p>"This is a phenomenon called 'interchange instability' where instabilities in the magnetic field react with the different densities of the gases in the protostellar disk, resulting in an outward expelling of magnetic flux. We dubbed this a baby star's 'sneeze' as it reminded us of when we expel dust and air at high speeds," he explained.</p>

Humans may witness personality change after organ transplant: Study

<p>Scientists spotted a massive, car-sized asteroid two days before it had an extremely close shave with Earth on Thursday (April 11).&nbsp;</p>

<p>To everyone's relief, the 9.4-foot space rock, although came very close to Earth, made a harmless pass by the planet.</p>

<p>The newly-discovered asteroid 2024 GJ2 is around the size of a car and after it was spotted by astronomers they calculated that the space rock would pass by Earth at a mere distance of 19.3 thousand kilometres from Earth.&nbsp;</p>

<p>This is just three per cent of the distance between the Moon and the Earth. According to the European Space Agency (ESA), 2024 GJ2 measures between 2.5 and 5 metres (8.2 and 16 feet).</p>

<p>Its size means that it is an asteroid with a weight class which would have burned up in the atmosphere of the Earth if its orbit intersected with ours more directly.</p>

<p>As per the astronomers, the asteroid made its closest approach at 2:28:42 p.m. EDT, when it was at a distance of 12,298 kilometres from Earth on Thursday (April 11).</p>

<p>The asteroid will not return&nbsp;till 2093, as per the near-Earth Objects Coordination Centre of the ESA. However, at that time, the asteroid will not fly as close as it did this time.</p>

<p>In 2093, asteroid GJ2 is expected to fly as close as 205,947 kilometres from us, which is 10 times farther than the distance at which it flew this time.&nbsp;</p>

<p>Around 35,000 near-Earth asteroids have been catalogued by NASA to date, although very few of them threaten&nbsp;our planet.</p>

<h2><strong>What are asteroids and how does NASA track them?</strong></h2>

<p>As per the scientists, asteroids are space rocks and some of them are also made of metal and orbit around the Sun.</p>

<p>Some asteroids are tiny and some are as huge as boulders. The asteroids can also fly even hundreds of kilometres across.&nbsp;</p>

<p>These asteroids have remained preserved in the solar system from the time it came into existence some 4.6 billion years ago.</p>

<p>The asteroids can also cause massive damage and hence, the space agencies track them. A range of instruments are used by the US space agency NASA to track the asteroids.</p>

Scientists spotted a massive, car-sized asteroid two days before it had an extremely close shave with Earth on Thursday (April 11). To everyone's relief, the 9.4-foot space rock, although came very close to Earth, made a harmless pass by the planet.

Scientists spotted a massive, car-sized asteroid two days before it had an extremely close shave with Earth on Thursday (April 11). To everyone's relief, the 9.4-foot space rock, although came very close to Earth, made a harmless pass by the planet. The newly-discovered asteroid 2024 GJ2 is around the size of a car and after it was spotted by astronomers they calculated that the space rock would pass by Earth at a mere distance of 19.3 thousand kilometres from Earth. This is just three per cent of the distance between the Moon and the Earth. According to the European Space Agency (ESA), 2024 GJ2 measures between 2.5 and 5 metres (8.2 and 16 feet). Its size means that it is an asteroid with a weight class which would have burned up in the atmosphere of the Earth if its orbit intersected with ours more directly.

It now fears boulders may collide with Mars As per the astronomers, the asteroid made its closest approach at 2:28:42 p.m. EDT, when it was at a distance of 12,298 kilometres from Earth on Thursday (April 11). The asteroid will not return till 2093, as per the near-Earth Objects Coordination Centre of the ESA. However, at that time, the asteroid will not fly as close as it did this time. In 2093, asteroid GJ2 is expected to fly as close as 205,947 kilometres from us, which is 10 times farther than the distance at which it flew this time. Around 35,000 near-Earth asteroids have been catalogued by NASA to date, although very few of them threaten our planet. What are asteroids and how does NASA track them? As per the scientists, asteroids are space rocks and some of them are also made of metal and orbit around the Sun. Some asteroids are tiny and some are as huge as boulders. The asteroids can also fly even hundreds of kilometres across. These asteroids have remained preserved in the solar system from the time it came into existence some 4.6 billion years ago. The asteroids can also cause massive damage and hence, the space agencies track them. A range of instruments are used by the US space agency NASA to track the asteroids.

Car-sized asteroid comes eerily close to Earth, much closer than even the Moon

<p>A study found that hospital sinks are the most likely source for spreading drug-resistant bacteria. The research was&nbsp;based on a superbug outbreak in a pediatric ward at the Toho University Omori Medical Center in Tokyo in 2017. The first case of the superbug was detected in a one-year-old boy hospitalised for heart disease in June 2016.</p>

<p>In March 2017, nine months later, a 15-year-old boy became the second person&nbsp;to contract the dangerous&nbsp;superbug.</p>

<p>Following this, the outbreak extended to affect 19 pediatric patients. Upon investigation, it was discovered that nine sinks were contaminated with CPE. Among these, six were located in hospital rooms with CPE-positive patients, while the remaining three were found in a nurse centre, a waste room, and an ice machine.</p>

<p>Genomic analysis found out&nbsp;the presence of bacterial strains such as "Klebsiella variicola, Klebsiella quasipneumoniae, and Escherichia coli."</p>

<p>Despite replacing all sinks in the pediatric ward with new ones properly disinfected with hydrogen peroxide, CPE contamination persisted, the team found.</p>

<p>Moreover, DNA sequences suggested that the resistance mechanism might have been transferred from one bacterial species to another within the hospital.</p>

<p>The team noted, "The discovery of the same bacterial species in sinks in adjoining rooms indicates that pathogen transmission may be possible from one sink to another via the drains and connected plumbing."</p>

Do you know why 38 SpaceX satellites crashed in 2022? Indian scientists say...

<p>Fast ageing is becoming more common in newer births and this could be linked to a higher incidence of early-onset solid tumours, according to research presented at the American Association for Cancer Research (AACR) Annual Meeting 2024, held April 5-10.</p>

<p>The new research was presented at the American Association for Cancer Research (AACR) Annual Meeting 2024.</p>

<p>“We all know cancer is an ageing disease. However, it is really coming to a younger population. So, whether we can use the well-developed concept of biological ageing to apply that to the younger generation is a really untouched area,” Yin Cao, the senior author of the study said.</p>

<h2><strong>What is biological age?</strong></h2>

<p>Biological age is different from chronological age (the number of years a person has been alive).&nbsp;It refers to the age of one's cells and tissues based on physiological evidence. For instance, if someone is healthy and fit for their age, their biological age might be lower than their chronological age. Likewise, if someone is in poor physical condition, their biological age may be higher.<br />
“Unlike chronological age, biological age may be influenced by factors such as diet, physical activity, mental health, and environmental stressors. Accumulating evidence suggests that the younger generations may be ageing more swiftly than anticipated, likely due to earlier exposure to various risk factors and environmental insults,” she added.</p>

<p>The study aimed to determine if accelerated ageing, i.e. one's biological age being higher than the chronological age, contributes to the development of&nbsp;cancers at a young age.&nbsp;</p>

<p>The research analysed data from almost 1,50,000 participants in the UK Biobank database and calculated their biological age using nine blood biomarkers such as albumin, alkaline phosphatase, creatinine, C-reactive protein, glucose, mean corpuscular volume, red cell distribution width, white blood cell count, and lymphocyte proportion.</p>

<p>The biological age trend showed that those who were born in or after 1965 had a 17% higher chance of accelerated ageing compared to those who were born between 1950 and 1954.</p>

<p>“By examining the relationship between accelerating ageing and the risk of early-onset cancers, we provide a fresh perspective on the shared etiology of early-onset cancers. If validated, our findings suggest that interventions to slow biological ageing could be a new avenue for cancer prevention, and screening efforts tailored to younger individuals with signs of accelerated ageing could help detect cancers early," Tian said.</p>

<p>The study discovered that a standard deviation increase in accelerated ageing was linked to a 42% higher risk of developing lung cancer, a 22% higher risk of gastrointestinal cancer, and a 36% higher risk of uterine cancer early on. The research could be a game changer in the early diagnosis and prevention of cancer.</p>

<p>Tian highlighted the potential implications of these findings, suggesting that interventions aimed at slowing biological ageing could be a novel approach to cancer prevention.</p>

<p>Since the study only had participants from the United Kingdom it might mean that the findings of this research might not apply to people with different genetic backgrounds and environmental conditions.</p>

Accelerated ageing is heightening cancer risk in younger population: Study

<p>An American satellite, in a recent space scare, narrowly escaped destruction after a close encounter with a Russian spacecraft. Though the incident took place on February 28, officials only recently learned that the spacecraft came within a mere 10 metres of collision.</p>

<p>The near collision left NASA officials on edge as there were risks involved from the&nbsp;potential debris had the two craft hit each other. It could be dangerous for astronauts aboard the International Space Station (ISS).</p>

<p>NASA's deputy administrator Colonel Pam Melroy while expressing the gravity of the situation, said,&nbsp;“It was very shocking personally and for all of us at NASA."&nbsp;</p>

<p>Collisions can produce a large amount of debris which can remain in orbit for a long time and may pose a hazard to other spacecraft. The increased presence of debris can also exacerbate the risk of further collisions.&nbsp;</p>

Close call! Russian spacecraft narrowly dodges collision with US satellite by a mere 10 metres

<p>Remains of ancient foxes, that were once domesticated, were found buried with their owners at an archaeological site in Argentina. These foxes, called Dusicyon avus, were kept as pets by hunter-gatherers some 1500 years back, in Patagonia, Argentina.</p>

<p>Previously, some studies opined that after the arrival of European dogs, people started disregarding foxes as pets. However, a recent study shows that climate change was the actual reason for their extinction among various other factors, and not the arrival of European dogs.</p>

<p>The study was conducted in parts of South America by Ophelie Lebrasseur among others, who is a zooarchaeologist at the University of Oxford. During the study, the team also found the remains of a&nbsp;fox that had “been deliberately buried alongside the person in the grave,” told Lebrasseur to Live Science.&nbsp;</p>

<p>Lebrasseur is a co-author of the new study, which was led by molecular biologist Cinthia Abbona of Argentina's Institute of Evolution, Historical Ecology and Environment (IDEVEA) in Mendoza.</p>

<h2><strong>Proof of people keeping foxes as pets in parts of South America</strong></h2>

<p>The remains of a fox buried with a human were found at the Cañada Seca site. Researchers initially thought that the bone specimens were from the Lycalopex genus of South American foxes.&nbsp;</p>

<p>However, upon carrying out precise measurements and DNA analysis, it was later found to be the remains of Dusicyon avus.</p>

<p>An analysis of the carbon and nitrogen isotopes present in the fox bones indicated that the animal had eaten a plant-rich diet similar to that of the person buried in the grave, said Lebrasseur. Wild foxes were generally habitual of eating more meat, but the fox found inside the grave had been eating whatever the human ate.</p>

<p>"The most plausible explanation is that this fox was a valuable companion to the hunter-gatherer groups," the authors wrote in the study.</p>

<p>"Its strong bond with human individuals during its life would have been the primary factor for its placement as a grave good after the death of its owners or the people with whom it interacted," they wrote.</p>

<h2><strong>Spread of dogs as pets in South America</strong></h2>

<p>Dogs (Canis familiaris) first came to the South American continent about 4000 years ago, but by 3000 years ago, their spread seems to have stopped north of Patagonia.</p>

<p>Due to this, the first evidence of dogs in the region is from the 16th century, when some indigenous societies started breeding dogs of European descent.</p>

<p>It is highly unlikely that the modern dogs of the region could have descended from a mixture of dogs and foxes, as was thought previously.</p>

During the study, the team also found the remains of a fox that had “been deliberately buried alongside the person in the grave,” told Lebrasseur to Live Science. Lebrasseur is a co-author of the new study, which was led by molecular biologist Cinthia Abbona of Argentina's Institute of Evolution, Historical Ecology and Environment (IDEVEA) in Mendoza. Proof of people keeping foxes as pets in parts of South America The remains of a fox buried with a human were found at the Cañada Seca site. Researchers initially thought that the bone specimens were from the Lycalopex genus of South American foxes. However, upon carrying out precise measurements and DNA analysis, it was later found to be the remains of Dusicyon avus.

Wild foxes were generally habitual of eating more meat, but the fox found inside the grave had been eating whatever the human ate.

"Its strong bond with human individuals during its life would have been the primary factor for its placement as a grave good after the death of its owners or the people with whom it interacted," they wrote. Spread of dogs as pets in South America Dogs (Canis familiaris) first came to the South American continent about 4000 years ago, but by 3000 years ago, their spread seems to have stopped north of Patagonia.

It is highly unlikely that the modern dogs of the region could have descended from a mixture of dogs and foxes, as was thought previously. (With inputs from agencies)

<p>Scientists, in a new study, have hinted that&nbsp;meteorites may soon disappear from the icy plains of Antarctica due to climate warming.&nbsp;</p>
