Microsoft reveals 40 jobs AI will take over sooner -  Check which jobs are still safe

<p>Research has found that men born in the summer season are more likely to be depressed later in life. The revelation was made by scientists at the Kwantlen Polytechnic University in British Columbia, Canada. An international survey conducted by them found that men born in summer are at a higher risk of developing depression over the years as compared to men born in other seasons. Notably, this was only found to be true for men and not women. This is because of the environmental risk factors the mothers are exposed to throughout the year, which differ in various seasons. Gizmodo reported that the author of the study, Mikael Mokkonen, got the idea to study seasons and their effect on mental health from horoscopes. He told the publication that when someone asked him if he believed in horoscopes, he started "wondering if there could potentially be a biological basis for them, in terms of how a person’s birthday could be associated with physiological or mental features."

<p>The interstellar object racing towards the inner solar system has intrigued astronomers around the world. Harvard scientist Avi Loeb thinks that it could be an object sent by aliens to study Earth and the entire star system. This theory has been panned by critics who say it is highly unlikely that it is a spacecraft sent by an intelligent alien civilisation. Loeb's theory has triggered panic among some people who think Earth is under threat of an alien attack. Now, Loeb has come up with another idea about the 3I/ATLAS, putting forward the idea that a spacecraft already zooming through the region near Jupiter could take a closer look at this interstellar object. In a paper yet to be peer reviewed, he suggests that NASA's Juno, launched in 2011 to study Jupiter, could intercept the object. He also has the exact date this could happen - March 14, 2026. He says if Juno accelerates by 2.6 kilometres per second on September 14, 2025, it could come face to face with 3I/ATLAS.

However, what Juno can do is use its scientific instruments to "probe the nature of 3I/ATLAS from a close distance," Loeb stated. "The close encounter of 3I/ATLAS to Jupiter provides a rare opportunity to shift Juno from its current orbit around Jupiter to intercept the path of 3I/ATLAS at its closest approach to Jupiter," he wrote in a blog post about his plan to learn more about the cosmic object. Another problem with using Juno to study the mysterious visitor is how much fuel it has left after being in space for 14 years. However, Loeb thinks it is possible to "rejuvenate Juno’s mission and extend its scientific lifespan beyond" and unravel the interstellar object. This move could make it clear if it indeed is an alien probe, as proposed by Loeb.

<p>NASA-ISRO Synthetic Aperture Radar (NISAR) launched the Geosynchronous Satellite Launch Vehicle (GSLV-MkII) from the Satish Dhawan Space Centre in Sriharikota on July 30. NISAR is a joint venture of ISRO and NASA. It has been developed to give a detailed view of the Earth to observe and measure some of the planet's most complex processes.&nbsp;</p>

<p>This is the 16th time a GSLV rocket is being used, specially prepared for this important Earth mission. The rocket is about 51 metres tall. And it weighs as much as 70 elephants, nearly 420 tonnes at lift-off. GSLV-F16 is strong enough to carry satellites weighing more than two small cars all the way up into space. &nbsp;</p><h2>Why is NISAR riding this rocket?</h2><p>NISAR isn’t just any satellite; it’s heavy (about 2,800 kg) and packed with sensitive science gadgets. It needs a rocket that’s powerful AND accurate to reach the exact spot in space. GSLV-F16’s special technology, especially its super-cold (cryogenic) top stage, makes sure NISAR gets there safely so its radars can do their important job circling Earth.</p><h2>GSLV-F16 A proud part of India’s space story</h2><p>The GSLV family of rockets is a key ingredient in India’s space journey. It’ll lift satellites up to help us with climate, navigation, TV, and even science partnerships. With GSLV-F16 and NISAR, India is showing the world it can support big, clever space projects, joining hands with NASA and leading the way to discoveries from space.</p><h2>What will happen next?&nbsp;</h2><p>Around 19 minutes after the rocket lifts off, the GSLV-F16 will inject the NISAR satellite into a 743-km sun-synchronous orbit.

<p>Scientists have warned that a fault line in Canada that has been lying dormant for years is showing signs of seismic activity and can trigger a massive earthquake. A study conducted by the University of Victoria (UVic) states that this threat lies in northwestern Canada’s Yukon Territory. The Tintina fault stretches around 1,000 kilometres and cuts northwest. It has been believed to be quiet for over 40 million years. But researchers from the university say that a 130-kilometre portion of the fault near Dawson City likely witnessed a huge earthquake during the Quaternary Period, SciTech Daily reported. This spans from 2.6 million years ago to the present. They added that the fault line has also shifted sideways by a total of 450 kilometres during its entire lifetime. This was deduced after studying imagery taken by satellites, aircraft, and drones. Scientists believe that the fault line has been deceiving humans till now and holds the potential to trigger big earthquakes in the future. The study was published in Geophysical Research Letters.

 The Tintina fault in Canada’s Yukon Territory has been believed to be silent for 40 million years. However, scientists say that might not be true, and it might be building pressure, which can soon trigger a massive earthquake because of it.

<p>Dr Vinay Prasad resigned as the top vaccine and gene therapy official of the US Food and Drug Administration (FDA) on Tuesday (July 29) in the wake of a vilification campaign led by right-wing influencer Laura Loomer. Loomer had slammed Prasad for allegedly denying drug approvals for rare diseases, and for his past support of left-leaning figures like Senator Bernie Sanders. The resurfacing of his past social media posts, identifying himself as a political liberal, and joking about having a Donald Trump 'voodoo doll' may have contributed to his exit, according to reports in the US media.</p>

<h2>Prasad played a role in ending US Covid vaccine mandate</h2><p>“Dr. Prasad did not want to be a distraction to the great work of the FDA in the Trump administration and has decided to return to California and spend more time with his family,” said Andrew Nixon, a Health and Human Services spokesperson, confirming Prasad's resignation just three months into the post.<br>Prasad had expressed some conservative views aligning with those of Health Secretary Robert Kennedy Jr, sharing his criticism of Covid pandemic measures and vaccine scepkticism.&nbsp;</p><p>FDA Commissioner Marty Makary called Prasad, who had taken up the post of director of the FDA’s Center for Biologics Evaluation and Research only in May, an 'impeccable scientist'.</p><p>After he took over in May, Prasad and Makary had announced new COVID-19 vaccine policies, limiting their use to those over 65 or at high risk, with further studies required for younger populations.</p><h2>Dr Vinay Prasad resigned in the wake of gene therapy drug controversy</h2><p>Prasad came under scrutiny for having cracked down on Sarepta Therapeutics due to deaths linked to its gene therapy drug Elevidys. After initially halting its use, Prasad later allowed it for some lower-risk children.</p><p>Amid the controversies, Prasad was labelled by a section of the media as a Bernie Sanders acolyte.</p><h2>More about Dr Vinay Prasad who left FDA vaccine job</h2><p>Vinayak "Vinay" Kashyap Prasad is a hematologist-oncologist and health researcher, and professor of epidemiology and biostatistics at University of California San Fransico (UCSF).<br>Before joining the FDA, he was a prominent UCSF oncologist known for his research on cancer drugs, health policy, and financial conflicts in drug approvals. He is the author of the books <i>Ending Medical Reversal</i> (2015) and <i>Malignant</i> (2020) and hosts the podcast, <i>Plenary Session</i>. Born to Indian immigrant parents, Prasad is known for challenging lax FDA approval standards.</p><h2>Dr Vinay Prasad life and career</h2><p>Prasad was raised near Cleveland, Ohio, and northern Indiana and graduated from Michigan State University in 2005 with a double major in philosophy and physiology.

<p>Marine animals make noise in the ocean, and it changes depending on their diet and the climate. A study has found that over the years, the symphony created by blue and fin whales has decreased in number, National Geographic reported. Scientists say the underwater songs offer a window into the ocean world, and how marine species are impacted by human activity. A 51-kilometre-long cable stretching from the California coastline along the seafloor and 3,000 feet below the surface has a two-inch metal cylinder at one end. This hydrophone, an underwater microphone, captures the sounds of the ocean and the creatures that live in it. In a study published earlier this year, John Ryan, a biological oceanographer at the Monterey Bay Aquarium Research Institute, stated that the hydrophone picked up clear patterns in whale song across seasons and years over six years in the central California Current Ecosystem. The whale songs started in July 2015, and over the years, no change was observed in the songs of Humpback whales. However, blue and fin whales were not singing as much.

Ghostly silence from blue whales is an ominous sign for the world

<p>Tsunamis, the massive displacement of water caused by earthquakes, landslides, volcanic eruptions or man-made causes, are some of the most destructive natural disasters in the world. As the world grapples with yet another tsunami event following an 8.8 magnitude earthquake in Russia on Wednesday (July 20), here is a look at some of the biggest tsunamis based on wave height and death toll.</p><h2>Tsunami classification based on wave heights</h2><p>These destructive waves are generally classified as megatsunamis of wave heights above 100 metres, large tsunamis of 30–100 metres and moderate tsunamis of 20–30 metres. Wave heights alone, however, may not translate into destruction. Whether tsunamis hit populated coastal areas will have to be taken into account.&nbsp;</p><h2>Tsunami wave height is not an indication of destruction</h2><p>While megatsunamis reach mind-boggling heights, &nbsp;they cause relatively fewer deaths as they often occur in remote or sparsely populated areas. The most lethal tsunamis in recorded history, on the other hand, had more modest wave heights but occurred near dense coastal populations with little or no warning. The 2004 Indian Ocean tsunami remains the most devastating in terms of human loss, while the 1958 Lituya Bay tsunami had the highest wave height since records began.</p><p>There may have been even more destructive tsunamis in the past, particularly in the prehistoric period, before recordings started. The list below avoids such events.</p><h2>Megatsunamis - wave height above 100 metres</h2><p>Megatsunamis are exceptionally large waves, caused by landslides or volcanic collapses rather than tectonic plate movements. Although some reached unimaginable heights, most occurred in remote areas, sparing large populations.</p><h3>Lituya Bay, Alaska, USA (1958)</h3><p>This tsunami was triggered by a landslide following a magnitude 7.8 earthquake. This was the tallest wave ever recorded at 524 metres or 1,719 feet. The wave destroyed everything in its path along the bay, but only two deaths were reported, due to the remote location.</p><h3>Spirit Lake, Mount St &nbsp;Helens, USA (1980)</h3><p>A landslide during the eruption of Mount St Helens caused a megatsunami in Spirit Lake, with waves reaching 260 metres or 850 feet. Despite its immense size, the event resulted in no deaths due to the uninhabited area surrounding the lake.</p><h3>Vajont Dam Disaster, Italy (1963)</h3><p>One of the most tragic man-made environmental disasters, this megatsunami was caused by a landslide into a reservoir behind the Vajont Dam. The impact created a wave 250 meters or 820 feet high, resulting in the toppling down of the dam. The tsunami flooded several towns, and is estimated to have killed around 2,000 people.</p><h3>Taan Fiord, Alaska, USA (2015)</h3><p>A massive landslide caused by glacial retreat in a remote Alaskan fjord generated a wave reaching 193 metres high. It was not a populated area and no casualties were reported.</p><h3>Karrat Fjord, Greenland (2017)</h3><p>This megatsunami was triggered by a landslide into the fjord, producing waves of around 100 metres high. At least 11 buildings in the village of Nuugaatsiaq were destroyed. Only four people were killed, as the area of impact was sparsely populated.</p><h3>Ambon Island, Indonesia (1674)</h3><p>An earthquake near the Hitu Peninsula generated a tsunami with waves as high as 100 metres, killing more than 2,000 people and devastating coastal communities.</p><h2>Large tsunamis - wave height of 30–100 metres</h2><p>Most of these large tsunamis resulted from undersea earthquakes and affected populated coastal areas. Even though their height is smaller than megatsunamis, they caused more human destruction, having hit in populated areas.<br>&nbsp;</p><h3>Indian Ocean tsunami (2004)</h3><p>This was the deadliest tsunami in recorded history in terms of human casualties. It was triggered by a massive, magnitude 9.1 undersea earthquake off the coast of Sumatra in Indonesia. The waves reached up to 51 metres and swept across 14 countries. At the end of it, &nbsp;nearly 230,000 people were killed across continents, all the way from Asia to Africa.</p><h3>Krakatau volcano eruption and tsunami, Indonesia (1883)</h3><p>The tsunami of 1883 was a result of the Krakatau volcano eruption. Waves of up to 150 feet were recorded, and an estimated 36,000 people were killed. The volcanic ash that filled the atmosphere led to long-lasting effects on the climate.</p><h3>Sanriku tsunami, Japan (1896)</h3><p>A magnitude 7.6 earthquake led to a tsunami with heights of 125 feet hitting Japan's northeastern coast. The disaster killed around 22,000 people and wiped out entire coastal villages.</p><h2>Tohoku Tsunami, Japan (2011)</h2><p>This was yet another destructive tsunami, triggered by a magnitude 9.0 earthquake off Japan’s east coast. The waves were as high as 130 feet. At the end of the devastation, some 20,000 people were reported dead. It also led to the Fukushima nuclear power reactor accident and radiation. The 2011 tsunami caused an estimated $309 billion in damage, making it one of the costliest disasters in history.</p><h3>Lisbon, Portugal (1755)</h3><p>This is one of the earliest well-documented tsunamis of Europe. Caused by a massive earthquake across Portugal, Spain, and Morocco, the tsunami had waves of up to 100 feet. The death toll is uncertain, with estimates ranging from 10,000 to 100,000.</p><h2>Moderate tsunamis - wave height 20–30 metres</h2><p>These tsunamis are of lesser height, but were deadly as they occurred near coastal populations.</p><h3>Arica Earthquake and tsunami, Peru/Chile (1868)</h3><p>This tsunami was caused by a magnitude 8.5 earthquake near Arica. The waves, as high as 70 feet, moved across the Pacific, affecting the coasts of Hawaii, New Zealand, and Australia. It is estimated to have killed between 25,000 and 70,000 people.</p><h3>Valdivia earthquake and tsunami, Chile (1960)</h3><p>This tsunami came from the strongest earthquake since recordings began. The quake had a whopping magnitude 9.5 and the subsequent tsunami killed 1,655 people. The waves reached 80 feet, causing damage across the Pacific, including in Japan and Hawaii.</p>

The most lethal tsunamis in recorded history had more modest wave heights but occurred near dense coastal populations with little or no warning. The 2004 Indian Ocean tsunami remains the most devastating in terms of human loss

Tsunamis, the massive displacement of water caused by earthquakes, landslides, volcanic eruptions or man-made causes, are some of the most destructive natural disasters in the world. As the world grapples with yet another tsunami event following an 8.8 magnitude earthquake in Russia on Wednesday (July 20), here is a look at some of the biggest tsunamis based on wave height and death toll. Tsunami classification based on wave heights These destructive waves are generally classified as megatsunamis of wave heights above 100 metres, large tsunamis of 30–100 metres and moderate tsunamis of 20–30 metres. Wave heights alone, however, may not translate into destruction. Whether tsunamis hit populated coastal areas will have to be taken into account. Tsunami wave height is not an indication of destruction While megatsunamis reach mind-boggling heights, they cause relatively fewer deaths as they often occur in remote or sparsely populated areas. The most lethal tsunamis in recorded history, on the other hand, had more modest wave heights but occurred near dense coastal populations with little or no warning. The 2004 Indian Ocean tsunami remains the most devastating in terms of human loss, while the 1958 Lituya Bay tsunami had the highest wave height since records began. There may have been even more destructive tsunamis in the past, particularly in the prehistoric period, before recordings started. The list below avoids such events. Megatsunamis - wave height above 100 metres Megatsunamis are exceptionally large waves, caused by landslides or volcanic collapses rather than tectonic plate movements. Although some reached unimaginable heights, most occurred in remote areas, sparing large populations. Lituya Bay, Alaska, USA (1958) This tsunami was triggered by a landslide following a magnitude 7.8 earthquake. This was the tallest wave ever recorded at 524 metres or 1,719 feet. The wave destroyed everything in its path along the bay, but only two deaths were reported, due to the remote location. Spirit Lake, Mount St Helens, USA (1980) A landslide during the eruption of Mount St Helens caused a megatsunami in Spirit Lake, with waves reaching 260 metres or 850 feet. Despite its immense size, the event resulted in no deaths due to the uninhabited area surrounding the lake. Vajont Dam Disaster, Italy (1963) One of the most tragic man-made environmental disasters, this megatsunami was caused by a landslide into a reservoir behind the Vajont Dam. The impact created a wave 250 meters or 820 feet high, resulting in the toppling down of the dam. The tsunami flooded several towns, and is estimated to have killed around 2,000 people. Taan Fiord, Alaska, USA (2015) A massive landslide caused by glacial retreat in a remote Alaskan fjord generated a wave reaching 193 metres high. It was not a populated area and no casualties were reported. Karrat Fjord, Greenland (2017) This megatsunami was triggered by a landslide into the fjord, producing waves of around 100 metres high. At least 11 buildings in the village of Nuugaatsiaq were destroyed. Only four people were killed, as the area of impact was sparsely populated. Ambon Island, Indonesia (1674) An earthquake near the Hitu Peninsula generated a tsunami with waves as high as 100 metres, killing more than 2,000 people and devastating coastal communities. Large tsunamis - wave height of 30–100 metres Most of these large tsunamis resulted from undersea earthquakes and affected populated coastal areas. Even though their height is smaller than megatsunamis, they caused more human destruction, having hit in populated areas. Indian Ocean tsunami (2004) This was the deadliest tsunami in recorded history in terms of human casualties. It was triggered by a massive, magnitude 9.1 undersea earthquake off the coast of Sumatra in Indonesia. The waves reached up to 51 metres and swept across 14 countries. At the end of it, nearly 230,000 people were killed across continents, all the way from Asia to Africa. Krakatau volcano eruption and tsunami, Indonesia (1883) The tsunami of 1883 was a result of the Krakatau volcano eruption. Waves of up to 150 feet were recorded, and an estimated 36,000 people were killed. The volcanic ash that filled the atmosphere led to long-lasting effects on the climate. Sanriku tsunami, Japan (1896) A magnitude 7.6 earthquake led to a tsunami with heights of 125 feet hitting Japan's northeastern coast. The disaster killed around 22,000 people and wiped out entire coastal villages. Tohoku Tsunami, Japan (2011) This was yet another destructive tsunami, triggered by a magnitude 9.0 earthquake off Japan’s east coast. The waves were as high as 130 feet. At the end of the devastation, some 20,000 people were reported dead. It also led to the Fukushima nuclear power reactor accident and radiation. The 2011 tsunami caused an estimated $309 billion in damage, making it one of the costliest disasters in history. Lisbon, Portugal (1755) This is one of the earliest well-documented tsunamis of Europe. Caused by a massive earthquake across Portugal, Spain, and Morocco, the tsunami had waves of up to 100 feet. The death toll is uncertain, with estimates ranging from 10,000 to 100,000. Moderate tsunamis - wave height 20–30 metres These tsunamis are of lesser height, but were deadly as they occurred near coastal populations. Arica Earthquake and tsunami, Peru/Chile (1868) This tsunami was caused by a magnitude 8.5 earthquake near Arica. The waves, as high as 70 feet, moved across the Pacific, affecting the coasts of Hawaii, New Zealand, and Australia. It is estimated to have killed between 25,000 and 70,000 people. Valdivia earthquake and tsunami, Chile (1960) This tsunami came from the strongest earthquake since recordings began. The quake had a whopping magnitude 9.5 and the subsequent tsunami killed 1,655 people. The waves reached 80 feet, causing damage across the Pacific, including in Japan and Hawaii.

<p>Leonardo da Vinci was not just a painter. He was also a sculptor, an architect, and even an engineer and a scientist. In fact, one of his scientific sketches hides the secret to better drones. Da Vinci made drawings of machines that didn't exist at the time and were only invented years later. His innovative ideas included vehicles that could fly, go underwater and some amazing weapons. A team of scientists has uncovered that they are not merely sketches but offer a lot more for today's modern machines. IFLScience reported that a new paper by the Department of Mechanical Engineering at Johns Hopkins University states that a sketch of a flying machine made by da Vinci in the 15th century holds clues to creating quieter drones that are more efficient. It features an aerial singular corkscrew propeller, which needed to be spun by men at its base, resulting in it taking off.

It will travel at the speed of 16,904 miles per hour and will safely skip the Earth at a distance of approximately 1.29 million kilometres. NASA assured that the asteroid posed no threat but emphasised the critical need for continuous surveillance of near-Earth objects, as tracking these asteroids helps improve planetary defense from potential future cosmic collision threats. How will asteroid 2025 OL1 help scientists study? Close monitoring plays a significant role, as it offers scientists the chance to study an asteroid up close, better understand its trajectory, and refine detection techniques for future near-Earth objects. The latest observations by NASA confirmed that asteroid 2025 OL1 will not come close enough to endanger Earth. It has clarified that in order to be classified as potentially hazardous, a celestial visitor must pass within 7.4 million kilometres of our planet, and it must be at least 85 metres wide. Therefore, 2025 OL1 meets the distance and size criterion, as it is the closest approach of 1.29 million kilometres, so it is well outside the danger zone.

Will asteroid 2025 OL1 hit Earth on July 30? Here's what NASA says

<p>A researcher who has spent eight years studying an inscription found at Serabit el-Khadim in Egypt's Sinai Peninsula has claimed that the words could mean "zot m'Moshe," Hebrew for "This is from Moses." This particular place is an ancient Egyptian mine, and if it does mean what Bar-Ron, the expert, says it does, it could prove that the Book of Exodus is true and that Moses was a real person. This inscription is part of a collection of over two dozen Proto-Sinaitic texts that were seen for the first time in the early 1900s. Scientists believe that these writings were etched by Semitic-speaking workers in the late 12th Dynasty, around 1800 BC. Bar-Ron studied high-resolution images and 3D scans of the texts, Mail Online reported. His analysis led him to conclude that they are linked to a figure named Moses, either by someone who dedicated it to him or could have been etched by Moses himself. He is a prominent figure in the Bible. According to the religious text, Moses is the one whom God gave the Ten Commandments on Mount Sinai. He says that his findings hint at the presence of religious tensions in the region years ago. One of the examples is the reference to "El," a deity that finds mention in early Israelite worship. There are also signs of the Egyptian goddess Hathor's name being defaced.

It could now cure cancer</strong></a></p><h2><strong>Experts warn this could lead to misinterpretation of history</strong></h2><p>Bar-Ron has a supporter in his academic advisor, Dr Pieter van der Veen, who also confirmed that it does say "This is from Moses." He said, "You're absolutely correct, I read this as well, it is not imagined!" However, other experts do not agree with Bar-Ron and his interpretation of the inscription. They argue that even though Proto-Sinaitic is the earliest known alphabet, its characters are extremely hard to decipher. One of them has warned that such decoding of inscriptions can twist facts and present a wrong picture of history. Dr Thomas Schneider, Egyptologist and professor at the University of British Columbia, says the Moses claims are "unproven and misleading."

Inscriptions found in an ancient Egyptian mine dating to around 1800 BC are possibly proof that Moses was a real person, and that everything in the Book of Exodus is true. While one scientist says it carries a reference to Moses, others say that it is not possible. 

A researcher who has spent eight years studying an inscription found at Serabit el-Khadim in Egypt's Sinai Peninsula has claimed that the words could mean "zot m'Moshe," Hebrew for "This is from Moses." This particular place is an ancient Egyptian mine, and if it does mean what Bar-Ron, the expert, says it does, it could prove that the Book of Exodus is true and that Moses was a real person. This inscription is part of a collection of over two dozen Proto-Sinaitic texts that were seen for the first time in the early 1900s. Scientists believe that these writings were etched by Semitic-speaking workers in the late 12th Dynasty, around 1800 BC. Bar-Ron studied high-resolution images and 3D scans of the texts, Mail Online reported. His analysis led him to conclude that they are linked to a figure named Moses, either by someone who dedicated it to him or could have been etched by Moses himself. He is a prominent figure in the Bible. According to the religious text, Moses is the one whom God gave the Ten Commandments on Mount Sinai. He says that his findings hint at the presence of religious tensions in the region years ago. One of the examples is the reference to "El," a deity that finds mention in early Israelite worship. There are also signs of the Egyptian goddess Hathor's name being defaced. Also Read: Fungus in King Tutankhamun’s tomb killed dozens. It could now cure cancer Experts warn this could lead to misinterpretation of history Bar-Ron has a supporter in his academic advisor, Dr Pieter van der Veen, who also confirmed that it does say "This is from Moses." He said, "You're absolutely correct, I read this as well, it is not imagined!" However, other experts do not agree with Bar-Ron and his interpretation of the inscription. They argue that even though Proto-Sinaitic is the earliest known alphabet, its characters are extremely hard to decipher. One of them has warned that such decoding of inscriptions can twist facts and present a wrong picture of history. Dr Thomas Schneider, Egyptologist and professor at the University of British Columbia, says the Moses claims are "unproven and misleading."

Scientist flags a clue in ancient Egyptian mine that hints the Bible was true and Moses was real

<p>King Tutankhamun’s tomb has been a major point of thrill amongst archaeologists ever since it was discovered in 1922 by excavators led by the Egyptologist Howard Carter. However, several excavators died soon after, triggering rumours of a mummy's curse. No one knew at the time what had happened. Then, in the 1970s, the tomb of Casimir IV was discovered in Poland, and surprisingly, 10 scientists died after entering it. This time, researchers knew what had killed them - Aspergillus flavus, a toxic fungal spore. Investigators found evidence that the fungus that can cause lung infections was present in the tomb. This led them to establish that the same fungus also likely killed the excavators who entered King Tutankhamun’s tomb. Now, scientists have discovered yet another secret about this fungus. According to a recent study published in Nature Chemical Biology, certain isolated compounds from the fungus A. flavus can be used to destroy leukaemia cells. These compounds, called ribosomally synthesised and post-translationally modified peptides (RiPPs), can help develop new cancer treatments.

Cupriavidus metallidurans

<h2>The metabolism of the gold pooping bacteria</h2><p>Cupriavidus metallidurans has a highly specified metabolism, that allows it to survive in a toxic environment. It has evolved complex metal-resistance pathways and detoxification mechanisms embedded in its genetic makeup. When exposed to soluble gold ions which are usually lethal it excretes enzymes like CopA and CupA which are part of its metal efflux system. This enzymes help pump neutralise the toxic compound by reducing them in their inert form. In the case of gold the ions are reduced and precipitated as nanoparticulates which are excreted outside the cell.</p><h2>What are the real life implications?</h2><p>The gold conjuring ability of the Cupriavidus metallidurans could inspire a revolutionary leap in biomimetic mining, offering a sustainable innovative method compared to the gold extraction, that are often toxic and energy intensive. By mimicking the the bacteria's physiology scientists and engineers could develop bio-reactors or engineered microbes capable of extracting gold from e-waste, mine tailings, or low-grade ores. Thus not only reducing the environmental damage capacity, could also kickstart a bio-extracting industry, where microscopic organism literally convert waste into wealth in sustainable manner.</p>

Cupriavidus metallidurans is a bacterium that lives in the soil enriched with heavy metal waste and converts them into pure gold under its physiological process. This tiny microbe could be the key to creating wealth in a sustainable way.

Nature's weirdest ALCHEMIST! This tiny microbe eats poison poops pure gold

<p>Archaeologists in Spain have found proof that ancient humans ate small children 850,000 years ago. The gruesome discovery was made at the Gran Dolina cave site in Atapuerca, northern Spain, where they found a human neck bone, Mail Online reported. It was small, and so would have been a child who was probably between the ages of two and four at the time of his death. Researchers found butchery marks on it, which they say are clear signs that the child was brutalised and cannibalised. A team of researchers from the Catalan Institute of Human Paleoecology and Social Evolution (IPHES) has been working on the site for more than 30 years. Besides the neck bone, they also discovered some other bones and teeth. The child was a Homo antecessor, a species that was the last link between Homo sapiens and Neanderthals. Several of the other bones found over the years have cut marks. The archaeologists are certain that our ancestors were cannibals and ate children.

The vertebra presents clear incisions at key anatomical points for disarticulating the head. It is direct evidence that the child was processed like any other prey." Several adult bones were also unearthed at the site, which have defleshing marks on them, just like on animal bones eaten and discarded by humans.

Ancient humans ate little children thousands of years ago, according to archaeologists in Spain who have found proof at a site they have been studying for 30 years. The brutal practice shows Homo antecessor was brutal and exploited others for food.

Archaeologists in Spain have found proof that ancient humans ate small children 850,000 years ago. The gruesome discovery was made at the Gran Dolina cave site in Atapuerca, northern Spain, where they found a human neck bone, Mail Online reported. It was small, and so would have been a child who was probably between the ages of two and four at the time of his death. Researchers found butchery marks on it, which they say are clear signs that the child was brutalised and cannibalised. A team of researchers from the Catalan Institute of Human Paleoecology and Social Evolution (IPHES) has been working on the site for more than 30 years. Besides the neck bone, they also discovered some other bones and teeth. The child was a Homo antecessor, a species that was the last link between Homo sapiens and Neanderthals. Several of the other bones found over the years have cut marks. The archaeologists are certain that our ancestors were cannibals and ate children.

The vertebra presents clear incisions at key anatomical points for disarticulating the head. It is direct evidence that the child was processed like any other prey." Several adult bones were also unearthed at the site, which have defleshing marks on them, just like on animal bones eaten and discarded by humans.

<p>Human landing on Mars might become a reality in the coming years. In preparation for that day, NASA and other space agencies have sent several missions to the Red Planet. One of them was the Perseverance rover that carried the Ingenuity helicopter with it in 2021. It became the first chopper to land and take off from the Martian surface. Now, a defence contractor has released a new design concept to succeed the iconic Mars chopper. The plan is to have multiple choppers land on different spots on Mars at the same time. Virginia-based AeroVironment (AV) has partnered with NASA’s Jet Propulsion Laboratory (JPL) on the Mars chopper plan. Called the Skyfall mission concept, the helicopters will help further plans of landing humans on Mars one day. The Mars helicopters will scout the landscape for the best places for people.

<p>Scientists are baffled by a strange radio signal picked up by the most advanced radio telescopes that defies the laws of Physics. The bizarre cosmic object named CHIME J1634+44 is called a long-period radio transient in astronomy as it repeats signals at long intervals. As the star fizzles out, the period between the emissions should ideally increase. But with this object, the time interval is becoming shorter, and the signals are being sent more quickly. This phenomenon is completely against the known principles of the universe, which is what has left them wondering about it. The long-period radio transient had more strange characteristics. CHIME J1634+44 is also one of the most polarised long-period radio transients ever discovered, meaning the radio waves released by it twist in a perfect spiral while travelling. In these two ways, the object not only breaks the known laws of the universe, but also pushes the case for something new and unknown.

<p>Women often complain about how terrible the dating scene is on apps. This is because it really is. Scientists have analysed online dating sites and revealed that most men swipe right for women who are more attractive than they are. This tends to lower the chances of having a successful match that could turn out to be something more in future. According to the researchers, this is more likely to happen between people with similar levels of desirability. The opposite was true for women, who mostly chose men who were lower on the desirability scale. This means that the matches that turn out to be successful often mean that men are settling for less attractive mates. "Women nominate on average slightly less desirable mates, and men send ties (swipes) to women who are on average considerably more desirable than themselves," the researchers wrote. Most matches end up happening because of rejections instead of first preferences. The study was carried out by a team from the Ludwig Maximillian University of Munich, in Germany, and the University of Manchester. It was published in the journal Plos One.

<p>Avi Loeb, an Israeli-American theoretical physicist known for talking about aliens, now thinks that the interstellar comet spotted in the solar system is an artificial object sent by an advanced alien civilisation. The Harvard professor points out the cosmic object's trajectory, size and behaviour to suggest that it doesn't appear to be a natural space rock, and is likely a spacecraft. 3I/ATLAS is only the third known interstellar object ever recorded in our solar system. It was detected on July 1 by NASA's ATLAS telescope in Chile and has been classified as a comet. Loeb told Newsweek, "The retrograde orbital plane of 3I/ATLAS around the Sun lies within 5 degrees of that of Earth... The likelihood of that coincidence out of all random orientations is 0.2 per cent." However, other experts have quashed his claims, saying there is nothing that points to it being an alien probe. The comet has travelled from another star system. Scientists have said that it is probably even older than our solar system. It could have taken it billions of years to get here. But Loeb thinks that 3I/ATLAS is so large that it is extremely unlikely it could have naturally taken this journey to reach us. &nbsp;Also Read: <a href="https://www.wionews.com/science/interstellar-visitor-solar-system-is-only-the-third-other-two-objects-oumuamua-and-comet-with-huge-tail-1751518381560"><strong>Interstellar visitor spotted is only the third: One of the other two appeared to be an 'alien vessel'</strong></a></p><p>Also Read:<strong> </strong><a href="https://www.wionews.com/science/voyager-spacecraft-crossed-wall-of-fire-to-reach-interstellar-space-what-is-it-1749714537835"><strong>Voyager spacecraft crossed 'wall of fire' to reach interstellar space. What is it?</strong></a></p><h2><strong>Nothing natural about the interstellar object: Avi Loeb</strong></h2><p>The comet is travelling at 60 kilometres per second, and Loeb claims that there is no natural cosmic process that would let it travel in this manner towards the inner solar system. He told MailOnline, "An alternative is that the object targets the inner solar system by some technological design." After the object was spotted for the first time, scientists noted its extremely elliptical orbit and high speed, and both of them pointed to its origins lying outside the solar system. 3I/ATLAS has come from the constellation Sagittarius and is heading towards the inner solar system. Its closest approach to the Sun is expected on &nbsp;October 30, when it will be 210 million km from our star, that is somewhere around the orbit of Mars. It is not expected to reach Earth.</p><h2><strong>How did such a mammoth object travel all this way to the solar system?</strong></h2><p>The sheer size of the interstellar visitor also hints that it is not a natural object, Loeb says. Right now, it is 490 million km from Earth. Its size has been measured based on the amount of light it reflects. This calculation states that it is around 20-24km in diameter. It is 200 times larger than 'Oumuamua, the thin and 100-metre-long interstellar visitor that took a trip to the solar system in 2017. Loeb doesn't think an object of this size can travel all the way here without dying out. He told MailOnline that there are about a million objects on the scale of 'Oumuamua for each object that is 24 kilometres in size. "But we haven't seen a million 'Oumuamua-sized interstellar objects before seeing this one; it's very strange," he pointed out.

He used previous data to calculate how many objects of this size could exist in the Milky Way. He multiplied this number by the mass of 3I/ATLAS, and the results made "zero sense". He says there is not enough mass to make ample rocks of this size. This means that 3I/ATLAS is a lot rarer than its appearance in our Solar System suggests. Since there aren't a lot of similar objects floating around, it seems strange that one that does is aiming for our inner solar system, Loeb said. The Harvard physicist also dismissed the comet theory, saying there is no direct evidence of dust or gas being released by the object. The &nbsp;'reddening' caused by dust is how it was concluded to be a comet. Loeb says this could be simply because the object is red.</p>

Avi Loeb, known for his theories on aliens, thinks that the interstellar object in our solar system is a spacecraft sent by aliens. He points to its trajectory, size and speed to state that it is almost impossible that such a natural cosmic object could have travelled so far.

The Harvard professor points out the cosmic object's trajectory, size and behaviour to suggest that it doesn't appear to be a natural space rock, and is likely a spacecraft. 3I/ATLAS is only the third known interstellar object ever recorded in our solar system. It was detected on July 1 by NASA's ATLAS telescope in Chile and has been classified as a comet. Loeb told Newsweek, "The retrograde orbital plane of 3I/ATLAS around the Sun lies within 5 degrees of that of Earth... The likelihood of that coincidence out of all random orientations is 0.2 per cent." However, other experts have quashed his claims, saying there is nothing that points to it being an alien probe. The comet has travelled from another star system. Scientists have said that it is probably even older than our solar system. It could have taken it billions of years to get here. But Loeb thinks that 3I/ATLAS is so large that it is extremely unlikely it could have naturally taken this journey to reach us.

What is it? Nothing natural about the interstellar object: Avi Loeb The comet is travelling at 60 kilometres per second, and Loeb claims that there is no natural cosmic process that would let it travel in this manner towards the inner solar system. He told MailOnline, "An alternative is that the object targets the inner solar system by some technological design." After the object was spotted for the first time, scientists noted its extremely elliptical orbit and high speed, and both of them pointed to its origins lying outside the solar system. 3I/ATLAS has come from the constellation Sagittarius and is heading towards the inner solar system. Its closest approach to the Sun is expected on October 30, when it will be 210 million km from our star, that is somewhere around the orbit of Mars. It is not expected to reach Earth. How did such a mammoth object travel all this way to the solar system? The sheer size of the interstellar visitor also hints that it is not a natural object, Loeb says. Right now, it is 490 million km from Earth. Its size has been measured based on the amount of light it reflects. This calculation states that it is around 20-24km in diameter. It is 200 times larger than 'Oumuamua, the thin and 100-metre-long interstellar visitor that took a trip to the solar system in 2017. Loeb doesn't think an object of this size can travel all the way here without dying out. He told MailOnline that there are about a million objects on the scale of 'Oumuamua for each object that is 24 kilometres in size. "But we haven't seen a million 'Oumuamua-sized interstellar objects before seeing this one; it's very strange," he pointed out.

Loeb has even written a paper that will be published by the Research Notes of the AAS, detailing the scenarios that can facilitate such a mammoth object to reach our solar system. He used previous data to calculate how many objects of this size could exist in the Milky Way. He multiplied this number by the mass of 3I/ATLAS, and the results made "zero sense". He says there is not enough mass to make ample rocks of this size. This means that 3I/ATLAS is a lot rarer than its appearance in our Solar System suggests. Since there aren't a lot of similar objects floating around, it seems strange that one that does is aiming for our inner solar system, Loeb said. The Harvard physicist also dismissed the comet theory, saying there is no direct evidence of dust or gas being released by the object. The 'reddening' caused by dust is how it was concluded to be a comet. Loeb says this could be simply because the object is red.

Expert says interstellar object 3I/ATLAS is alien spacecraft: 3 reasons why he thinks so

<p>Humans have never seen dinosaurs in flesh and blood and have built on the fossils collected over the years. We have imagined them roaring and standing several feet taller than us. But a new study has suggested that not all dinosaurs were beasts. Scientists have discovered a group of herbivorous dinosaurs that looked like birds with feathers all over their bodies and tweeted like them, too. This is based on the research carried out on new fossilised dinosaur bones, which included parts of the voice box. Published in PeerJ by Chinese scientists, the study states the discovery of fossils belonging to a 2-foot-long new dinosaur species, Pulaosaurus qinglong. The species has been named after "Pulao," a mythical Chinese dragon known for a loud voice. The species belongs to Neornithischia, a subgroup of Ornithischia, a herbivorous dinosaurs whose pelvic region resembled birds.

There is an almost full skeleton, comprising vertebrae, limbs, pelvis, bones of the larynx or voice box, and even some rare soft tissue structures. This is the first time neornithischian dinosaur specimens were found in this hotspot. Till now, only small theropods and early birds were studied from the region.

Dinosaurs are known for their mighty roar. But scientists think not all dinosaurs were this loud. Some of them not only looked like birds, but also had a similar voice. Scientists analysed a fossilised voice box found in Chinas dinosaur hotspot, only the second such fossil.
