Are black holes quiet eaters? NASA decodes elements that satiate the cosmic giants

<p>Weight loss options are expanding rapidly. A new study presents&nbsp;potential findings for a non-surgical obesity treatment. This procedure involves controlled burning of a portion of the stomach's mucus lining.</p>

<p>The participants in the small trial saw an average weight loss of 8%&nbsp;from their starting weight, along with a notable decrease in hunger.</p>

<p>The process is known as endoscopic mucosal ablation, which is a method already used to remove precancerous or other unusual bits of tissue from the digestive tract.&nbsp;</p>

<p>In the process, patients first drink a fluid in order to protect the stomach’s tissues, then doctors&nbsp;send an endoscope down through the esophagus to the uppermost portion of the stomach, also called the gastric fundus.&nbsp;</p>

<p>Once there, the endoscope will burn the moist, inner lining of the fundus where mucus is produced.</p>

<p>The key to this procedure lies in the fundus, a part of the stomach responsible for a significant portion of our hunger pangs. This area is the primary producer of ghrelin, a hormone that signals hunger when our stomach is&nbsp;empty. Conversely, ghrelin levels decrease after eating. The goal is to safely reduce hunger by burning a portion of the fundus lining, thereby destroying enough ghrelin-producing cells to promote lasting weight loss.</p>

<p>Researchers running the first-in-human trial of this method announced their early results at the academic conference Digestive Disease Week.</p>

Participants’ average level of self-reported hunger also dropped by a third, while their stomach’s capacity for food and drink decreased by 42%.</p>

<p>It's important to note that this is a very early study with only a few participants. The results haven't been reviewed by other scientists yet, so more research is needed before getting too excited.&nbsp;</p>

<p><strong>Massive sunspot AR3664:</strong> A gigantic sunspot, AR3664, on the&nbsp;surface of the&nbsp;sun&nbsp;ballooned and grew so massive that it can fit 15 Earths and has become the most active one in the current solar cycle.&nbsp;</p>

<p>Now, this gigantic sunspot released a powerful&nbsp;X-class solar flare towards the Earth&nbsp;which&nbsp;led&nbsp;to radio blackouts in various areas.&nbsp;</p>

<p>The National Oceanic and Atmospheric Administration (NOAA) Space Weather Prediction Center had earlier this week&nbsp;issued a warning&nbsp;of increased&nbsp;solar flare&nbsp;risk from the&nbsp;Sun.</p>

<p>"Region 3664 has grown considerably and has become much more magnetically complex,"&nbsp;read NOAA's SWPC reports. "This has&nbsp;led to&nbsp;increased solar flare probabilities over the next several days," it added.</p>

<p>The giant sunspot has fired more powerful solar flares&nbsp;in recent days&nbsp;than estimated.&nbsp;This&nbsp;included a colossal X-class solar flare&nbsp;which&nbsp;was&nbsp;released on May 9 morning and peaked at 5:13 am&nbsp;EDT (0913 GMT).</p>

<p>Solar flares are eruptions from the&nbsp;surface of the&nbsp;sun&nbsp;which&nbsp;release intense bursts of electromagnetic radiation. According to their size, the solar flares have been categorised into lettered groups and the X-class&nbsp;is considered the most powerful.&nbsp;</p>

<p>Because of this, the X-flare led to shortwave radio blackouts across parts of Europe and Africa. The radio blackouts happened due to extreme ultraviolet radiation&nbsp;which&nbsp;was&nbsp;released&nbsp;during the eruption&nbsp;and&nbsp;the strong pulse of X-rays.</p>

<h2><strong>Sunspot visible from Earth&nbsp;</strong></h2>

<p>The sunspot AR3664,&nbsp;which&nbsp;is&nbsp;spread&nbsp;across 124,000 (200,000 kilometres), is currently 15 times wider than Earth, as per Spaceweather.com.&nbsp;</p>

<p>The sunspot is so&nbsp;huge&nbsp;that it is visible from Earth without&nbsp;any need for&nbsp;magnification. Those&nbsp;who have&nbsp;a pair of&nbsp;solar eclipse&nbsp;glasses&nbsp;can use them to observe the&nbsp;sun&nbsp;and observe the mammoth sunspot cross the solar disk.&nbsp;</p>

<h2><strong>NASA shares images of dancing loops</strong></h2>

<p>In a recent post, NASA shared two GIFs (graphics interchange format)&nbsp;which&nbsp;captured the moment&nbsp;two powerful solar flares&nbsp;were unleashed&nbsp;by the&nbsp;sun.&nbsp;</p>

Massive sunspot AR3664: A gigantic sunspot, AR3664, on the surface of the sun ballooned and grew so massive that it can fit 15 Earths and has become the most active one in the current solar cycle.

Massive sunspot AR3664: A gigantic sunspot, AR3664, on the surface of the sun ballooned and grew so massive that it can fit 15 Earths and has become the most active one in the current solar cycle. Now, this gigantic sunspot released a powerful X-class solar flare towards the Earth which led to radio blackouts in various areas. The National Oceanic and Atmospheric Administration (NOAA) Space Weather Prediction Center had earlier this week issued a warning of increased solar flare risk from the Sun. "Region 3664 has grown considerably and has become much more magnetically complex," read NOAA's SWPC reports. "This has led to increased solar flare probabilities over the next several days," it added. Also Read: Sun fires massive solar flares directly at Earth; Australia, Japan and China witness radio blackouts The giant sunspot has fired more powerful solar flares in recent days than estimated. This included a colossal X-class solar flare which was released on May 9 morning and peaked at 5:13 am EDT (0913 GMT). Solar flares are eruptions from the surface of the sun which release intense bursts of electromagnetic radiation. According to their size, the solar flares have been categorised into lettered groups and the X-class is considered the most powerful. Because of this, the X-flare led to shortwave radio blackouts across parts of Europe and Africa. The radio blackouts happened due to extreme ultraviolet radiation which was released during the eruption and the strong pulse of X-rays. Sunspot visible from Earth The sunspot AR3664, which is spread across 124,000 (200,000 kilometres), is currently 15 times wider than Earth, as per Spaceweather.com. The sunspot is so huge that it is visible from Earth without any need for magnification. Those who have a pair of solar eclipse glasses can use them to observe the sun and observe the mammoth sunspot cross the solar disk. NASA shares images of dancing loops In a recent post, NASA shared two GIFs (graphics interchange format) which captured the moment two powerful solar flares were unleashed by the sun. Watch: Boeing to send Starliner space capsule with 2 astronauts' The two solar flares erupted on May 7 and May 8 from the sunspots AR3663 and AR3664. "You make a loop-de-loop and pull, and your Sun is looking cool! Late at night on May 7 and in the wee hours of May 8, the Sun emitted this powerful pair of solar flares. These two energetic flashes with dancing loops were captured by @NASAGoddard's Solar Dynamics Observatory, which always has its eye on the Sun," wrote NASA, in the caption of the post.

NASA detects the farthest supermassive black hole ever observed

<p>With Black Hole Week in full swing, let's explore NASA's upcoming Nancy Grace Roman Space Telescope, which is poised to embark on a groundbreaking mission: hunting for primordial black holes dating back billions of years to the Big Bang.</p>

<p>The mission is set to launch in late 2026.</p>

<p><strong>Black holes</strong></p>

<p>The term black hole normally conjures up images of massive celestial entities. However, Roman aims to detect far smaller, ancient counterparts that are theorised to have a mass similar to Earth.&nbsp;</p>

<p>A team of researchers has published research in the journal Physical Review D postulating exactly how Roman will set upon hunting primordial black holes.</p>

<p><strong>Also read |&nbsp;<a href="https://www.wionews.com/trending/elon-musk-claims-aliens-have-never-visited-earth-and-heres-the-proof-719996">Elon Musk claims aliens have never visited Earth and here's the proof...</a></strong></p>

<p>"Detecting a population of Earth-mass primordial black holes would be an incredible step for both astronomy and particle physics because these objects can't be formed by any known physical process," said William DeRocco, a postdoctoral researcher at the University of California Santa Cruz, team lead of the research.</p>

<p>In a statement, as quoted by space.com, he added, "If we find them, it will shake up the field of theoretical physics."</p>

<p>Dubbed "primordial black holes," these enigmatic entities, if proven to exist, could challenge our understanding of the universe's early epochs some 13.8 billion years ago.</p>

<p>These miniature black holes with masses comparable to asteroids or even Earth might have originated during the universe's inception, some 13.8 billion years ago, speculate scientists.</p>

<h2><strong>Doubtful existence</strong></h2>

<p>As per the report, the existence of primordial black holes remains a matter of speculation.</p>

<p>One famous personality whose research contributed to the doubts surrounding their existence is Stephen Hawking.</p>

<p>Hawking's theory of Hawking radiation proposes that black holes "leak" radiation and eventually evaporate. For primordial black holes to survive billions of years without evaporating, they must defy Hawking's predictions.</p>

<h2><strong>How will Roman seek to defy the postulations of Hawking's radiation theory?</strong></h2>

<p>Roman's strategy for detecting these cosmic fossils hinges on gravitational microlensing, a phenomenon predicted by Einstein's general relativity. Currently, microlensing helps scientists find rogue planets, but it has the potential to help prove the existence of primordial black holes.</p>

<p>This principle suggests that massive objects can bend light, causing distortions observed from Earth. By monitoring these distortions, Roman could help prove the presence of primordial black holes, which, as per speculation, could potentially be disguised as Earth-mass rogue planets.</p>

<p>"There's no way to tell between Earth-mass black holes and rogue planets on a case-by-case basis," said DeRocco.&nbsp;</p>

<p>"Roman will be extremely powerful in differentiating between the two statistically."</p>

Dubbed "primordial black holes," these enigmatic entities, if proven to exist, could challenge our understanding of the universe's early epochs some 13.8 billion years ago. These miniature black holes with masses comparable to asteroids or even Earth might have originated during the universe's inception, some 13.8 billion years ago, speculate scientists. Doubtful existence As per the report, the existence of primordial black holes remains a matter of speculation. One famous personality whose research contributed to the doubts surrounding their existence is Stephen Hawking. Hawking's theory of Hawking radiation proposes that black holes "leak" radiation and eventually evaporate. For primordial black holes to survive billions of years without evaporating, they must defy Hawking's predictions. Also read | Human trial of Elon Musk's Neuralink hits snag as brain chip begins to detach How will Roman seek to defy the postulations of Hawking's radiation theory? Roman's strategy for detecting these cosmic fossils hinges on gravitational microlensing, a phenomenon predicted by Einstein's general relativity. Currently, microlensing helps scientists find rogue planets, but it has the potential to help prove the existence of primordial black holes. This principle suggests that massive objects can bend light, causing distortions observed from Earth. By monitoring these distortions, Roman could help prove the presence of primordial black holes, which, as per speculation, could potentially be disguised as Earth-mass rogue planets. "There's no way to tell between Earth-mass black holes and rogue planets on a case-by-case basis," said DeRocco. "Roman will be extremely powerful in differentiating between the two statistically."

Scientists locate two black holes closest to Earth in cosmic backyard

<p>New research offers new clues on Ludwig van Beethoven's death and health problems. The German composer is one of the most influential figures in the history of Western music in the transitional period between the Classical and Romantic eras. He is known for his exemplary work.&nbsp;</p>

<p>Beethoven died after a prolonged illness in the Schwarzspanierhaus, Vienna, on March 26, 1827, at the age of 56. However, there have been several theories about his illness and still nobody knows for certain what caused the liver and kidney disease that led to his demise.&nbsp;</p>

<p>In 2023, an international group of researchers published a paper in the journal Current Biology, which found that Beethoven did not have lead poisoning, a theory which had been widely believed. In fact, the hair sample used for DNA sequencing was not Beethoven's. It belonged to an Ashkenazi Jewish woman. The lead poisoning theory was cancelled out.&nbsp;</p>

<p>But in a new research paper, published in the journal Clinical Chemistry, researchers analysed two locks of hair previously authenticated as Beethoven's. The findings revealed music composers could have suffered the effects of lead poisoning. However, it wasn't enough to kill him.&nbsp;</p>

<p>After his death, mourners continued to visit him to offer tribute even after a brutal craniotomy was performed by doctors to examine the folds in Beethoven's brain. They had removed his ear bones to determine why he lost his hearing. But they failed during the procedure.&nbsp;</p>

<p>Several reports have mentioned that strands of hair were plucked from his head after his death, and not a single one was left. Those hair samples have now become a tool for researchers to understand what exactly led to his illness and possibly know other family secrets.&nbsp;</p>

<p>Two hair bundles, identified as the Bermann and the Halm-Thayer locks, were used in the latest research. The locks had been authenticated in the 2023 genetic analysis, now analysed by Nader Rifai, who is a pathologist at Harvard Medical School, and his colleagues.&nbsp;</p>

<p>They measured the amount of lead, arsenic and mercury in the two hairlocks using clinically validated mass spectrometry methods. The sample had been first washed with detergent, dried, and weighed in order to reduce the risk of contamination through handling and storage.&nbsp;</p>

<p>The researcher found that lead concentration was 64 times higher than the upper limit in the Bermann lock. The lead concentration in the Halm-Thayer lock was 95 times greater than that reference range. They also found high levels of arsenic and mercury.&nbsp;</p>

<p>The researchers estimated that Beethoven's blood lead concentration would have been 69 to 71 µg/dL.

<p>Reducing aerosol emissions can have a cooling effect on Earth's climate. Aerosols are tiny particles suspended in the atmosphere, often released through human activities like burning fossil fuels and biomass, industrial processes, and natural events like volcanic eruptions. While aerosols can contribute to air pollution and have negative health effects, they also play a role in the Earth's climate system.</p>

<p>A recent study conducted by researchers at the Ocean University of China has put a spotlight on a concerning phenomenon - the exacerbation of global warming due to China's efforts to reduce aerosol emissions. These efforts, aimed at curbing air pollution, have unintentionally led to the formation of 'heat blobs' over the northeast Pacific region from 2010 to 2020.</p>

<p>The research team observed a major rise in temperatures, up to 1.8 degrees Fahrenheit, stretching from the Bering Strait across 1,000 miles to the Gulf of Alaska. This surge in temperature has had profound ecological repercussions, including fish die-offs, the mysterious disappearance of whales, and&nbsp;toxic algae blooms.&nbsp;</p>

<p>The study underscored the necessity for the Chinese government to reconsider its aerosol reduction policies, as the absence of these particles is predicted to further escalate temperatures in the northeast&nbsp;Pacific region.</p>

<h2><strong>Researchers simulate conditions&nbsp;</strong></h2>

<p>The researchers employed computer climate models to simulate two scenarios - one where East Asian emissions remained stable and another reflecting the reduction in aerosol levels over the past decade. The models revealed that while stable emissions did not significantly alter temperatures in other regions, reduced aerosol levels led to intensified heat waves in the northeast Pacific.</p>

<p>The mechanism behind this phenomenon lies in the diminished reflection of heat into space due to cleaner air.

China's aerosol reduction measures warming Pacific region, finds study

<p>A recent study has suggested there are alarming health risks posed by cancer-causing flame retardants used in car seats. Notably, flame retardants are chemicals added to seat materials to reduce flammability and the spread of fire. The findings are as per a recent peer-reviewed research conducted in the United States, media reports said.&nbsp;</p>

<p>Flame retardants, which work by interfering with the combustion process and interrupting the chemical reactions,&nbsp;were initially introduced into car seat foam to comply with safety regulations set forth by the US National Highway Traffic Safety Administration in the 1970s.</p>

<p>The study, led by Rebecca Hoehn, a researcher from Duke University, found that these chemicals, present in car cabin air, significantly endanger the health of individuals spending prolonged periods in vehicles.</p>

<p>The study, which examined air samples from 101 cars manufactured in 2015 or later, revealed that nearly&nbsp;99 per cent of samples contained flame retardants deemed carcinogenic or potentially carcinogenic by government standards. Among these chemicals, 1-chloro-isopropyl phosphate, identified as a potential carcinogen by the US National Toxicology Program, was prevalent in virtually all samples.</p>

Car cabins becoming toxic! Cancer-causing flame retardants are the cause, reveals study

<p>Scientists have&nbsp;found the best evidence to date for a rocky planet atmosphere outside our solar system in a major breakthrough for humanity's expedition to find life outside Earth. The breakthrough was achieved by the researchers using NASA's James Webb Space Telescope, who detected an atmosphere surrounding 55 Cancri e, an exoplanet located about 41 light-years from Earth.</p>

<p>The international research was published in the journal Nature.&nbsp;</p>

<h2><strong>About 55 Cancri e: What is it?</strong></h2>

<p>55 Cancri e is one of five known planets that orbit&nbsp;a sun-like star in the constellation Cancer.&nbsp;</p>

<p>It has a diameter nearly twice that of Earth and a density slightly smaller. Astrophysicists have classified the planet as a Super Earth. This means that&nbsp;it is larger than Earth, smaller than Neptune, and similar in composition to the planets in our solar system.</p>

<a class="close-mark close-div" href="#" id="jqclosemark">×</a></div>

<p>Brice-Olivier Demory, Professor of Astrophysics at the University of Bern and member of the National Centre of Competence in Research (NCCR) Planets said in an official statement: "55 Cancri e is one of the most enigmatic exoplanets. Despite enormous amounts of observing time obtained with a dozen of ground and space facilities in the past decade, its very nature has remained elusive, until today, when parts of the puzzle could finally be put together, thanks to the James Webb Space Telescope (JWST)".</p>

<h2><strong>James Webb is 'enabling a new type of science'</strong></h2>

Scientists have found the best evidence to date for a rocky planet atmosphere outside our solar system in a major breakthrough for humanity's expedition to find life outside Earth.

Scientists have found the best evidence to date for a rocky planet atmosphere outside our solar system in a major breakthrough for humanity's expedition to find life outside Earth. The breakthrough was achieved by the researchers using NASA's James Webb Space Telescope, who detected an atmosphere surrounding 55 Cancri e, an exoplanet located about 41 light-years from Earth. The international research was published in the journal Nature. About 55 Cancri e: What is it? 55 Cancri e is one of five known planets that orbit a sun-like star in the constellation Cancer. It has a diameter nearly twice that of Earth and a density slightly smaller. Astrophysicists have classified the planet as a Super Earth. This means that it is larger than Earth, smaller than Neptune, and similar in composition to the planets in our solar system.

Despite enormous amounts of observing time obtained with a dozen of ground and space facilities in the past decade, its very nature has remained elusive, until today, when parts of the puzzle could finally be put together, thanks to the James Webb Space Telescope (JWST)".

Is an ocean of magma creating atmosphere on this 'Super Earth'? The possibility has scientists excited

<p>In a bizarre new finding, a study published in the journal Biology Letters found that dice snakes go to extreme lengths to save themselves from predators, including faking their own deaths.&nbsp;</p>

<h2><strong>About the study</strong></h2>

<p>The study finds that the species of snake also known as Natrix tessellata, can fake their own death when attacked by predators by putting on a theatrical display which includes oozing&nbsp;“mouthfuls” of blood, smearing themselves with faeces, and even releasing foul-smelling musk from their butts.</p>

<p>Notably, dice snakes are not the only ones in the animal kingdom who fake their own death to avoid being eaten by predators, as it is a good tactic for the prey to create a distraction and escape.&nbsp;</p>

<p>Researchers recently found that calculating the biological age of our cells and tissue by adding up epigenetic modifications might not be the correct way.</p>

<p>Our cells carry a genetic code that guides the production of proteins vital for survival. Over time and through challenges, small changes are made, acting as 'genetic switches' that influence how cells follow these instructions without altering the code itself.</p>

<p>The biological age of our cells and tissues is frequently ascertained by adding up these changes. However, researchers have recently proven that the changes might fluctuate throughout the day, meaning that tests based on a single tissue sample are less exact than they could be.</p>

<p>Over 72 hours, the researchers examined several blood samples from a 52-year-old man, examining 17 distinct epigenetic clocks inside each specimen's collection of white blood cells.</p>

<p>They noticed a significant variation in 13 out of the 17 epigenetic clocks throughout the day, looking 'younger' in the early morning and 'older' around midday, with relative variations equal to approximately 5.5 years' worth of changes.

<p>"The majority of the aging studies investigating epigenetic clocks use whole blood as the tissue of interest. However, experiments in our lab and from other groups have shown that white blood cell subtype counts and their proportions oscillate with a 24 hour periodicity," statistician Karolis Koncevičius from Vilnius University and colleagues wrote in their published paper.</p>

<p>Relying on a single individual's samples allowed the team to focus on a specific set of changes. However, age changes were also observed by further analysing several blood samples collected from a small group over five hours.</p>

<h2><strong>What could be the reason behind&nbsp;variations&nbsp;in epigenetic clocks?</strong></h2>

<p>Some of these cellular age variations might be attributed to the fact that human blood includes various types of white blood cells at different times of the day. Even with a single kind of white blood cell as the focus, some metrics still showed age variation.</p>

<p>Scientists have always known that deep down in the core of the Earth, there exist&nbsp;two blobs the size of continents. One is under the African continent and the other one is under the Pacific Ocean.</p>

<p>Earthquakes are caused by a sudden movement along faults within the Earth, but new research by MIT scientists suggests that heavy snowfall and rain could play a role play in setting off tremors.</p>

<p>The study, published on Wednesday (May 8) in the journal Science Advances, indicates a potential link between heavy snowfall on Japan's Noto Peninsula and thousands of quakes measured there since late 2020.&nbsp;</p>

<p>William Frank, who is the study author and an assistant professor in MIT's Department of Earth, Atmospheric and Planetary Sciences (EAPS), said, "We see that snowfall and other environmental loading at the surface impacts the stress state underground, and the timing of intense precipitation events is well-correlated with the start of this earthquake swarm."</p>

<p>On January 1 this year, the west coast of Japan was struck by a massive magnitude-7.6 earthquake near the Noto Peninsula in Ishikawa prefecture. It was the strongest quake to hit the area in over a century. The quake killed 213 people and left 26,000 in emergency shelters.&nbsp;</p>

<p>The satellite images later revealed that the powerful quake even shifted its coastline by 800 kilometres. Since the initial earthquake, the Noto peninsula, which is located about 190 miles northwest of Tokyo on the Sea of Japan, experienced nearly 600 aftershocks.&nbsp;</p>

<p>Hundreds of small earthquakes have shaken up the Noto Peninsula since late 2020. The researchers analysed thousands of earthquakes that hit the peninsula.

Certain weather events, like heavy snowfall and rain, might trigger earthquakes: Study

<p><meta name="uuid" content="uuidd1wnVNk5rBYF" /></p>

<p>Pre-historic rock art&nbsp;discovered&nbsp;by archaeologists on the walls of sites located in the Atbai Desert in Eastern Sudan,&nbsp;builds a picture of the region that is very different from the present arid areas, and appears unbelievable.</p>

<p>Even though the region is currently arid, according to the&nbsp;artwork&nbsp;it once was filled with lush green bushes, pastures, water and also animal life.&nbsp;</p>

<p>Interestingly, the&nbsp;artwork&nbsp;is only around 4,000 years old&nbsp;which&nbsp;hints&nbsp;that&nbsp;most&nbsp;likely&nbsp;this part of the Sahara Desert went through a rapid and radical change in just a few millennia.&nbsp;</p>

<p>The archaeologists at Macquarie University, in a new study,&nbsp;have described the 16 rock art sites&nbsp;which&nbsp;were&nbsp;discovered&nbsp;in the deserts around Wadi Halfa, which is a city in northern Sudan close to the border with&nbsp;Egypt.</p>

<p>In the different figures depicted in the art, the&nbsp;researchers discovered illustrations of humans, antelopes, elephants, and giraffes.&nbsp;</p>

<p>According to the archaeologists, cattle also appeared often,&nbsp;which&nbsp;was surprising in the wake of the hyper-arid climate of the Atbai Desert.</p>

<p>The region today&nbsp;receives almost no annual rainfall&nbsp;which&nbsp;has made&nbsp;cattle pastoralism impossible. In contrast to this, the rock art displays that cattle farming was a common theme of people living in the area in 3000 BCE.&nbsp;</p>

<p>In a statement, researcher Dr Julien Cooper said, “It was puzzling to find cattle carved on desert rock walls as they require plenty of water and acres of&nbsp;pasture,&nbsp;and would not survive in the dry and arid environment of the Sahara today."</p>

<p>Cooper&nbsp;headed a team of archaeologists involved&nbsp;in the&nbsp;Atbai Survey Project in 2018 and 2019.&nbsp;</p>

<p>“The presence of cattle in ancient rock art is one of the most important pieces of evidence establishing a once ‘green Sahara’,” Cooper said.</p>

<h2><strong>Rainfall in Africa led to pastures in Sahara Dessert?</strong></h2>

<p>Africa&nbsp;between&nbsp;15,000 and 5,000 years&nbsp;ago&nbsp;received increased summer monsoon rainfall across the continent because of periodic variations in the orbit of Earth around the&nbsp;Sun.&nbsp;</p>

<p>Because of the downpours, the continent became a flourishing land&nbsp;of grassy pasture&nbsp;which&nbsp;was&nbsp;filled&nbsp;with freshwater lakes.&nbsp;</p>

<p>After the wet period&nbsp;came to an end, a drastic change took place in the region’s landscape along with many people and other animals who lived here.</p>

Pre-historic rock art discovered by archaeologists on the walls of sites located in the Atbai Desert in Eastern Sudan, builds a picture of the region that is very different from the present arid areas, and appears unbelievable.

Pre-historic rock art discovered by archaeologists on the walls of sites located in the Atbai Desert in Eastern Sudan, builds a picture of the region that is very different from the present arid areas, and appears unbelievable. Even though the region is currently arid, according to the artwork it once was filled with lush green bushes, pastures, water and also animal life. Interestingly, the artwork is only around 4,000 years old which hints that most likely this part of the Sahara Desert went through a rapid and radical change in just a few millennia. The archaeologists at Macquarie University, in a new study, have described the 16 rock art sites which were discovered in the deserts around Wadi Halfa, which is a city in northern Sudan close to the border with Egypt. In the different figures depicted in the art, the researchers discovered illustrations of humans, antelopes, elephants, and giraffes. According to the archaeologists, cattle also appeared often, which was surprising in the wake of the hyper-arid climate of the Atbai Desert. The region today receives almost no annual rainfall which has made cattle pastoralism impossible. In contrast to this, the rock art displays that cattle farming was a common theme of people living in the area in 3000 BCE.

Cooper headed a team of archaeologists involved in the Atbai Survey Project in 2018 and 2019. “The presence of cattle in ancient rock art is one of the most important pieces of evidence establishing a once ‘green Sahara’,” Cooper said. Rainfall in Africa led to pastures in Sahara Dessert? Africa between 15,000 and 5,000 years ago received increased summer monsoon rainfall across the continent because of periodic variations in the orbit of Earth around the Sun. Because of the downpours, the continent became a flourishing land of grassy pasture which was filled with freshwater lakes. After the wet period came to an end, a drastic change took place in the region’s landscape along with many people and other animals who lived here.

Water world, lava hell: Former NASA scientist hints at planets where alien life may exist

<p>A study has revealed the way salmon caught at different points in time are evolving genetically due to fish-catching activities. Atlantic Salmon, caught when fish are migrating to spawn, are genetically different from their other counterparts elsewhere.&nbsp;</p>

<p>The study on wild salmon in the northern Baltic Sea pointed out that during the early part of the fishing season, fishing activity chiefly targets salmon carrying a "large salmon genetic variant."&nbsp;</p>

<p>The variant guides Atlantic Salmon to grow large and to mature at an older age, an important characteristic for the fishing and viability of Salmon stocks.</p>

<p>The findings are published in the journal Evolutionary Applications.</p>

<h2><strong>How was the study done?</strong></h2>

<p>Scientists pursued genetic analyses on thousands of wild salmon caught between 1928 and 2020&nbsp;from the northern Baltic Sea region.&nbsp;</p>

<p>Fishers caught salmon with the "large salmon variant" more often in the early than late fishing season.</p>

<p>"This finding suggests that the timing of fishing may cause evolutionary changes in the age and size that Atlantic salmon reach before maturation. Intensive fishing especially in the early fishing season may lead to the 'large salmon variant' becoming rarer and to salmon spawning at a younger age and smaller size," the lead author of the study Antti Miettinen, PhD, from the Faculty of Biological and Environmental Sciences at the University of Helsinki, said in an official statement.&nbsp;</p>

<h2><strong>What does it mean?</strong></h2>

<p>The evolutionary impact of fishing in fewer large salmon is not good news for the diversity and viability of salmon populations and for fishers&nbsp;who value large catches.&nbsp;</p>

<p>The results of the study will help humanity understand the way the evolutionary selection pressures induced by human actions, in this case fishing, can affect wild fish populations and their characteristics.&nbsp;</p>

Salmon evolving to get smaller due to early season fishing, study suggests

<p>A 30-year study conducted in the United States suggested a concerning connection between the consumption of ultra-processed foods and a higher risk of premature death, with particular emphasis on ready-to-eat meat products and sugary drinks. Published in The BMJ, the research underscored the importance of reevaluating dietary habits for long-term health benefits.</p>

<p>Ultra-processed foods are products that have undergone extensive processing and often contain additives, preservatives, artificial flavours, colours, and other substances. These foods typically contain minimal amounts of whole foods and are often high in sugar, unhealthy fats, and sodium while lacking in essential nutrients like fibre, vitamins, and minerals.</p>

Also read | Have we 'already lost climate battle'?: April continues damning 11-month trend, emerges as hottest since 1940 According to a press release, American Indian/Alaska Native children have the highest rate of parent loss due to overdose (187/100,000) from 2011 to 2021, twice that of White and Black children (76.5/100,000 and 73/100,000 respectively). "It is devastating to see that almost half of the people who died of a drug overdose had a child. No family should lose their loved one to an overdose, and each of these deaths represents a tragic loss that could have been prevented," said Nora Volkow, MD, National Institute on Drug Abuse (NIDA) director. "These findings emphasise the need to better support parents in accessing prevention, treatment, and recovery services. In addition, any child who loses a parent to overdose must receive the care and support they need to navigate this painful and traumatic experience." (With inputs from agencies)

<p>Scientists have long been intrigued by the mysterious clicks of sperm whales, pondering the meaning&nbsp;behind their underwater conversations. Led by a team from the Massachusetts Institute of Technology (MIT), a groundbreaking study, detailed in Nature Communications on May 7, has unraveled this mystery using the power of machine learning.</p>

<p>As part of the study, researchers delved into the complex world of sperm whale communication by analysing nearly 8,719 clusters of clicks, known as codas.</p>

<p>Sperm whales produce these clicks by forcing air through nasal passages located in their large heads.

<p>The Dark Energy Camera (DECam) has captured what scientists&nbsp;are calling&nbsp;a massive&nbsp; 'God's hand', reaching out for a distant&nbsp;galaxy,&nbsp;named ESO 257-19 (PGC 21338). The&nbsp; massive&nbsp;formation is located 1,300 light-years from Earth within our Milky Way galaxy and&nbsp;is seen&nbsp;in the constellation Puppis.</p>

<h2><strong>What is God's hand?</strong></h2>

<p>Don't worry; there is nothing supernatural about it. God's hand is&nbsp;actually&nbsp;a cometary&nbsp; globule,&nbsp;named CG 4. Usually, cometary globules are hard to detect because they&nbsp;are formed&nbsp;of dense clouds of gas and dust surrounded by hot, ionised material.</p>

<p>The CG 4 is&nbsp;simply&nbsp;massive and huge, with its length extending for about eight light-years and its width extending 1.5 light-years across.</p>

<p>Maintaining optimal health involves more than just exercising and sleeping well. It requires a balanced approach to daily activities, including sitting, standing, light activity, and exercise.&nbsp;</p>

<p>While we intuitively recognise the benefits of standing over sitting and the importance of exercise and sleep, achieving the right balance among these activities remains a challenge. Questions arise, particularly regarding how to structure our day to maximise health benefits while minimising risks.</p>

<p>Now, research conducted on over 2,000 adults wearing body sensors for a week provided valuable insights into daily activity patterns and their correlation with health markers.</p>

<p>By analysing data on sitting, standing, light activity, and exercise, researchers identified optimal combinations that were associated with reduced risk factors for heart disease, stroke, and diabetes.</p>

<p>The average ideal distribution of time across a 24-hour period, taking into account all factors, were as follows:</p>

<ul>
	<li>Sitting: Six hours</li>
	<li>Standing: Five hours and 10 minutes</li>
	<li>Light-to-moderate physical activity (less than 100 steps per minute): Two hours and 10 minutes</li>
	<li>Moderate-to-vigorous physical activity (more than 100 steps per minute): Two hours and 10 minutes</li>
	<li>Sleeping: Eight hours and 20 minutes</li>
</ul>

<p>Current health guidelines typically focus on recommending a certain amount of moderate-to-vigorous physical activity per week.</p>

<p>However, emerging evidence suggests that how we spend our entire day, including time spent sitting, standing, and engaging in light activity, can significantly impact our health.</p>
