The team concluded that the animal’s hindlimbs generated most of the force needed for take-off, while the wings became important only after it had already accelerated.

Total Solar Eclipse 2026: For two NASA pilots, the eclipse on August 12 will last nearly three minutes in totality. The eclipse chasers will be covered by a weird and eerie shadow, with the aircraft going dark suddenly, instantly cooling the interiors.

The totality of the August 12 Solar Eclipse will last for nearly three minutes for two people. For parts of the Earth witnessing totality, the entire duration will be 2 minutes 18 seconds. Two NASA aviators are set to chase the eclipse as they get on a research plane from Keflavik Airport in Iceland on Wednesday.

As their plane cruises at a speed of 740 km/hr along the path of the eclipse, they will be covered in darkness for nearly 3 minutes, as compared to 2 minutes 18 seconds on the ground. This will give them more time to study the sun in its eclipsed state.

"Then all of a sudden, you’re hit with this slam of shadow," said Klemm, who has previously flown eclipse missions. He says you are surrounded by "a weird, eerie shadow", the temperature drops, and you feel the "need for more light from the instruments."

They will take several photos of the sun every second in different wavelengths of light. What they are expecting to capture are large, looping ribbons of plasma called prominences and magnetic explosions called nanoflares. A total solar eclipse is the only time when such features from the Sun can be viewed. Each nanoflare releases energy equivalent to thousands of atomic bombs. Observing them helps understand the reason why the corona, or outer atmosphere, measures more than 1,000,000C, while the surface is only 6,000C. The Total Solar Eclipse will cover the Arctic, Greenland, Iceland, and parts of Spain and Portugal. It will be the first total solar eclipse to be visible from mainland Europe since 1999.

<h2><strong>What happened to the SpaceX rocket?</strong></h2><p>The Falcon 9 launched from Florida in January 2025 carrying two private lunar landers, Firefly Aerospace's Blue Ghost and ispace's Resilience, into lunar orbit. The rocket's primary booster was designed to return safely to Earth. But the upper stage was left drifting in space after completing its mission.</p><p>It was never supposed to hit the Moon. But a combination of lunar gravity and solar activity eventually pushed the roughly 4,000 to 4,500kg rocket stage onto a collision course with the lunar surface.</p><p>Independent astronomers first noticed the unusual trajectory before it was confirmed by NASA's Centre for Near-Earth Object Studies.</p><p>The rocket, measuring around 12 metres long, eventually hit the Moon at about 8,700 kmph. Researchers estimate the impact packed the force of roughly three tonnes of TNT.</p><h2><strong>Satellite caught the Moon before and after the crash</strong></h2><p>Danuri's observations have given scientists an unusually useful record of the impact. Because the spacecraft passed over the region shortly before the collision, researchers can compare the lunar surface before the rocket hit with the landscape after the crash.</p><p>NASA's Lunar Reconnaissance Orbiter is also expected to observe the site during a later pass, providing another look at the crater and surrounding debris.</p><p>Researchers in Spain also believe they captured footage of the impact indirectly. The actual flash was hidden behind the Moon's limb, but astronomers say they may have recorded the plume of dust and debris thrown into space by the collision. Watch the stunning visuals here:</p>

<h2><strong>Why scientists are interested in the crash</strong></h2><p>The accidental collision is more than a dramatic space event. Scientists see it as a rare opportunity to study how large objects behave when they strike the lunar surface.</p><p>The Moon is regularly bombarded by meteoroids, but scientists often have little information about the exact size and mass of naturally occurring impactors. This time, they know the approximate mass, composition and trajectory of the object. That could allow researchers to study how the impact created a crater and how far material was thrown across the lunar surface.</p><p>The Moon has been deliberately used for similar experiments before. In 2006, the European Space Agency intentionally crashed its SMART-1 spacecraft into the lunar surface to study the resulting impact.</p>

A discarded SpaceX Falcon 9 rocket stage has crashed into the Moon at around 5,400 mph, creating a fresh crater estimated to be up to 27 metres wide. South Korea's Danuri spacecraft captured the lunar surface before and after the impact.

A discarded rocket stage of Elon Musk's SpaceX has slammed into the Moon at around 5,400 miles per hour, leaving behind a fresh crater on the lunar surface. Stunning visuals of the human-made crater have now been captured by a South Korean lunar spacecraft. The Korea Aerospace Research Institute's Danuri spacecraft flew over the impact site shortly after the Falcon 9 upper stage crashed into the lunar surface on Wednesday. The satellite made multiple passes over the area and captured images showing the terrain before and after the impact. Also read | Baba Vanga's 2026 prophecy: 2 predictions 'already came true', 3 terrifying ones remain. Details inside Another human-made crater on the Moon Scientists estimate that the impact could have created a crater up to 27 metres wide and around five metres deep. The pictures reveal a noticeably darker patch on the Moon where the rocket struck, with dust and debris scattered across the surrounding surface. KARI said Danuri began observing the region around 30 minutes before the collision and conducted eight imaging sessions in total. "Through this observation, changes in the terrain around the impact site and traces of ejecta spread were confirmed," the agency said.

Elon Musk's SpaceX rocket crashes into Moon at 5,400 mph: South Korean satellite captures shocking 'before and after' images

<p>Scientists have discovered a natural particle accelerator in the Milky Way blasting out protons with energies exceeding one quadrillion electron volts. These are some of the fastest-moving particles and the highest known energies in our galaxy. Humans have built colliders on Earth, but none even comes close to this cosmic accelerator. Named LHAASO J1912+1014u, it is located in the constellation Aquila. Astronomers think this object could provide clues to the origin of high-energy particles moving through space at almost the speed of light. The findings were published in The Astrophysical Journal.</p><p>&nbsp;</p><p>The particles emitted by this object carry energies thousands of times higher than the collision limits of Earth’s largest human-made particle accelerator, the Large Hadron Collider (LHC). First spotted in 2024, it was classified as a supernova remnant. But then a stream of gamma-ray emissions was observed bursting from the object.

A mysterious object is blasting energy at extremely high levels in the Milky Way, which astronomers say is a cosmic accelerator. However, its true identity remains a secret. Scientists are now trying to find more of these objects. 

Scientists have discovered a natural particle accelerator in the Milky Way blasting out protons with energies exceeding one quadrillion electron volts. These are some of the fastest-moving particles and the highest known energies in our galaxy. Humans have built colliders on Earth, but none even comes close to this cosmic accelerator. Named LHAASO J1912+1014u, it is located in the constellation Aquila. Astronomers think this object could provide clues to the origin of high-energy particles moving through space at almost the speed of light. The findings were published in The Astrophysical Journal. The particles emitted by this object carry energies thousands of times higher than the collision limits of Earth’s largest human-made particle accelerator, the Large Hadron Collider (LHC). First spotted in 2024, it was classified as a supernova remnant. But then a stream of gamma-ray emissions was observed bursting from the object. They are generated when accelerated particles collide with surrounding gas. This led scientists to conclude that it was a natural cosmic accelerator that boosts protons up to petaelectronvolt (PeV) energies, also known as a PeVatron. Triple observations revealed it was not a supernova remnant Initially thought to be a supernova remnant, researchers combined data across multiple wavelengths using data from three different observatories - NASA's Fermi-LAT, Japan's FUGIN radio telescope, and NASA's Chandra X-ray Observatory. This helped them rule out electrons as the source of the gamma-ray emissions and that they stemmed from accelerated protons. Tsunefumi Mizuno, associate professor at Hiroshima University’s Astrophysical Science Center and corresponding author of the study, said in a statement, "In this study, three arrows—Fermi-LAT GeV gamma-ray data, FUGIN radio data and Chandra X-ray data—are bundled together through a detailed multiwavelength modelling, revealing that our target, LHAASO J1912+1014u, is a cosmic-ray proton PeVatron." These findings can help explain the Milky Way’s most energetic cosmic rays that travel through the galaxy and affect events. Scientists think there could be many more cosmic accelerators out there which could soon be discovered.

<p>A mysterious object is blasting energy at levels thousands of times than the maximum energy humans can give a particle in Earth's largest and most powerful machine, the Large Hadron Collider (LHC). The identity of this object remains unknown.</p>

<p>Fresh genetic evidence has linked ancient Tamil settlements with present-day South Indian, Sri Lankan Tamil and broader South Asian populations, in one of the most significant breakthroughs in the study of Sangam-era ancestry.

New DNA research decoding 75,000 genetic markers from Keeladi, Konthagai, Adichanallur and Sivagalai has revealed links between ancient Tamils and South Asian populations, alongside insights into Sangam-era life. What was life like those days?

Fresh genetic evidence has linked ancient Tamil settlements with present-day South Indian, Sri Lankan Tamil and broader South Asian populations, in one of the most significant breakthroughs in the study of Sangam-era ancestry. Researchers at the Ancient DNA Lab in the Department of Genetics at Madurai Kamaraj University successfully extracted and analysed more than 75,000 genetic markers from human remains recovered from Konthagai, the burial site associated with Keeladi, along with samples from Adichanallur and Sivagalai. The lab was established in November 2022 to support Tamil Nadu's archaeological excavations. The latest findings are expected to be published in peer-reviewed international journals by December 2026, according to reports in Deccan Herald and other media outlets. Besides the 75,000 markers from Konthagai, about 9,000 and 6,000 markers were extracted from DNA samples at Adichanallur and Sivagalai, showing genetic proximity with South Indians, Sri Lankans and South Asians, said Prof G Kumaresan, Head of the Department of Genetics at MKU. From processing 4,000-5,000 markers in 2025, the researchers have made a major leap this year to around 75,000 markers. https://www.wionews.com/videos/historic-tomb-unearthed-archaeologists-reveal-1-400-year-old-secrets-1769800870744/embed The results have consistently aligned with ancestry patterns in the 1000 Genomes Project, one of the world's largest catalogues of human genetic variation. Kumaresan said the team plans additional rounds of analysis before releasing the complete dataset and publishing the findings. The department is preparing nine research papers covering ancient Tamil ancestry, agriculture, cuisine, textile production and other aspects of Sangam-era civilisation. Keeladi, a major site for tracing Sangam-era Tamil ancestry The new study adds to a growing body of evidence from Keeladi, a Sangam-era urban settlement discovered in 2014 by archaeologist K Amarnath Ramakrishna of the Archaeological Survey of India (ASI). Keeladi has been carbon-dated to around 2,600 years ago. Iron artefacts recovered from nearby Sivagalai have been dated to 3345 BCE, making them among the world's earliest known examples of smelted iron. Excavations at Keeladi have uncovered brick structures, drainage systems, industrial activity and Tamil-Brahmi inscriptions, suggesting the existence of an organised urban settlement in southern India during the Sangam period.

<p>Scientists have found that the enigmatic Blood Falls in Antarctica still harbour descendants of ancient sea creatures that have been trapped beneath the glacier for hundreds of thousands of years. The eerie red water comes from the Taylor Glacier and flows into Lake Bonney. The brine emerging from beneath the ice is rich in iron and turns red upon contact with air. This gives it a unique colour that resembles blood. Under the glacier resides a unique community of microorganisms, including marine diatoms, haptophytes, dinoflagellates and ciliates.</p><p>&nbsp;</p><p>These marine microorganisms typically live in the ocean. They became isolated when the glacier moved away and cut off the trapped seawater from the ocean. The discovery proves that the mysterious water is actually from the sea but got sealed beneath advancing ice years ago.

Blood Falls, the strangest occurrence in Antarctica, has revealed something peculiar about itself. Scientists have for years thought that the water in this formation is from the sea, even though it is isolated from the ocean. Now they know for sure that it is true.

Scientists have found that the enigmatic Blood Falls in Antarctica still harbour descendants of ancient sea creatures that have been trapped beneath the glacier for hundreds of thousands of years. The eerie red water comes from the Taylor Glacier and flows into Lake Bonney. The brine emerging from beneath the ice is rich in iron and turns red upon contact with air. This gives it a unique colour that resembles blood. Under the glacier resides a unique community of microorganisms, including marine diatoms, haptophytes, dinoflagellates and ciliates. These marine microorganisms typically live in the ocean. They became isolated when the glacier moved away and cut off the trapped seawater from the ocean. The discovery proves that the mysterious water is actually from the sea but got sealed beneath advancing ice years ago. The findings were published in the journal Nature Geoscience, in which researchers stated that "the subglacial brine–fed system at the Taylor Glacier Terminus retains marine–derived biological signatures long after physical separation from the ocean", calling it a “rare marine refuge.” Brine water in Blood Falls came from the sea?

<p>Yesterday, flare production was recorded at low levels, with 2 C-class and 2 B-class (weak) flares observed during the period, EarthSky reported. NOAA said that the largest flare was a C6.3 on August 2, followed by the strongest flare, which was a C1.3 from sunspot region AR4492 on the same day. On August 3, the sunspot region AR4498 fired a C1.0 flare.</p><h2><strong>Aurora predictions for August - Where to see auroras</strong></h2><p>Some predictions state that if the current solar conditions persist, auroras could also become visible much farther from the poles than usual. Meanwhile, satellites, radio communications, and power systems are also expected to take a hit from the solar material. Auroras are also predicted to occur in Edinburgh, Seattle, Toronto, Chicago, and even London and New York.</p><p>&nbsp;</p><p>The solar activity is expected to continue over August 3 - 5. Most likely, there will be C flares, although there is a 20 per cent chance for M-class (moderate) flares as well, with R1–R2, minor–moderate radio blackouts. The chances for X-class (strong) flares remain very low. The sunspots that will be responsible for this activity are AR4498 and AR4499.</p>

Decapeptide-12: Unveiling a precision peptide in pigmentation research

<p>A new study has revealed that a trail of two "ghost lineages" of extinct human populations lies hidden within our genome. But one of these ghost lineages left its DNA dispersed in all present-day people. Meanwhile, researchers reported Thursday (July 30) in the journal Science that the other, a "super-archaic" lineage, dates back nearly 2 million years.</p><p>&nbsp;</p><p>"These extinct populations may have lived hundreds of thousands, or even more than a million, &nbsp;years ago, yet traces of their genetic legacy remain preserved in our genomes today," said study co-author Priya Moorjani, a human evolutionary geneticist at the University of California, Berkeley.</p><p>&nbsp;</p><p>For more than ten years, scientists have discovered that DNA evidence indicates our species, Homo sapiens, once mated with now-extinct relatives such as Neanderthals and Denisovans. Most of the population not a part of sub-Saharan ancestry living today have nearly 1 per cent to 2.4 per cent Neanderthal ancestry, and Asians and Oceanians (people from the island nations of the Pacific Ocean) harbour approximately 0.1 per cent to 6 per cent Denisovan ancestry.</p><p>&nbsp;</p><p>However, scientists have speculated that contemporary humans may have crossbred with other now-extinct human groups that have not been detected yet. But the lack of ancient DNA samples makes it difficult to find out what these unidentified groups, often called ghost lineages, might have provided to our species.</p><p>&nbsp;</p><p>"Ancient DNA has transformed our understanding of human evolution, but it can only tell us about populations for which DNA has been preserved," Moorjani said. "DNA survives only under very specific conditions — typically in cold, dry environments, which means that much of our evolutionary history, particularly in Africa, other tropical regions, and at very deep timescales, remains inaccessible."</p><h2>Long-extinct ancestors</h2><p>In the new finding, Moorjani and her team members explained that everyone's genome has a record of their ancestry. They also investigated possibilities to uncover signs of "long-extinct ancestors preserved within the genomes of present-day people." They also developed a new technique to scan and compare over 500 complete genomes of present-day humans from around the world.</p><p><br>Drawing on this data, researchers reconstructed detailed genealogies for individual segments of each person's genome, building family trees that traced ancestral lineages back through every point of divergence and merging. Their focus centred on ancestors whose genetic makeup differed significantly from modern humans, an indicator that these lineages had branched off from the modern human line long ago.</p><p><br>"Most regions of our genome share a common ancestor relatively recently in our evolutionary history," Moorjani said. "Occasionally, however, we find stretches of DNA whose common ancestor lies much farther back in time, indicating they originated from a long-separated human lineage," she added.</p><p><br>What sets this method apart from earlier techniques is that it doesn't rely on fossil DNA to detect ancient genetic sequences within modern-human genomes. According to Moorjani, scientists no longer need to depend on rare, well-preserved fossils to learn about extinct human populations. Instead, the genomes of people alive today carry remnants of these ancient ancestors, and genealogical analysis can help uncover that concealed history.</p><p>&nbsp;</p><p><strong>Also read: </strong><a href="https://www.wionews.com/trending/world-s-largest-digital-camera-captures-over-500-000-galaxies-50-000-stars-in-one-stunning-image-1785657873100">World's largest digital camera captures over 500,000 galaxies, 50,000 stars in one stunning image</a></p><p><br>To validate the approach, researchers tested it experimentally, and it successfully identified Neanderthal and Denisovan ancestry within modern-human genomes. Beyond confirming known lineages, the method also revealed previously undocumented cases of interbreeding with extinct groups. Notably, the researchers found DNA from one "ghost lineage" present across all modern humans — evidence suggesting this group interbred with modern humans in Africa more than 50,000 years ago, predating the most recent wave of Homo sapiens migration out of Africa and into the rest of the world.</p><p><br>"Previous publications suggested that there might be ghost ancestry, ancestry from unknown archaic lineages in modern humans, but they hadn't concluded whether this unknown ancestry is present only in Africans or not, and when this introgression event happened," study co-author Yulin Zhang, a computational biologist at UC Berkeley, said in a statement. "We were actually able to find and map genomic locations in modern humans that are from this ghost lineage and show that this ghost ancestry is in all modern humans, not only in Africans."</p><p><br>This new DNA contains around 0.5 per cent to 1 per cent of the genomes of modern humans, comparable to the amount of Neanderthal DNA. It has been estimated that about 800,000 years ago this ghost lineage diverged from the ancestors of modern humans, about the same time Neanderthals and Denisovans did. The possible ghost lineage was found to be Homo heidelbergensis, which lived from about 700,000 to 200,000 years ago in Africa and Europe.</p><p><br>"I agree with their speculation that this ghost could have been the species Homo heidelbergensis, which was present in Africa as recently as 300,000 years ago," Chris Stringer, a paleoanthropologist at the Natural History Museum in London who was not involved in the study, said.</p><h2>‘Super-archaic’ human lineage</h2><p>Researchers also discovered that people from Oceania carry traces of a "super-archaic" human lineage that split from modern humans' ancestors roughly 1.8 million years ago, well before the common ancestor of modern humans, Neanderthals, and Denisovans emerged. This ancient DNA accounted for approximately 0.002% of the Oceanian genomes studied and was found embedded within regions of Denisovan ancestry, indicating it likely entered modern humans through interbreeding with Denisovans.</p><p><br>Fernando Villanea, a population geneticist at the University of Colorado Boulder uninvolved in the study, suggested the DNA's age points to Homo erectus as its likely original source, passed first into Denisovans and then into modern humans. This theory gains support from Yunxian skull fossils in China, which share certain features with Denisovan remains, though limited H. erectus genetic material has been analysed so far. "We see hybridisation being a common trait in the evolution of many other species, and these findings help us reframe our scientific thinking away from a mentality of human exceptionalism," Villanea said.</p><p><br>According to Villanea, these findings underscore that modern humans descend from multiple ancient species, making hybridisation the norm rather than the exception. These newly identified DNA segments cluster most densely in genome regions tied to immune function and metabolism, a pattern Moorjani says reflects how adapting to new pathogens and food sources has consistently driven human evolutionary pressure.</p>

For over a decade, DNA evidence has shown Homo sapiens once mated with extinct relatives like Neanderthals and Denisovans. Most non-sub-Saharan populations carry 1-2.4% Neanderthal ancestry, while Asians and Oceanians harbour roughly 0.1-6% Denisovan ancestry.

A new study has revealed that a trail of two "ghost lineages" of extinct human populations lies hidden within our genome. But one of these ghost lineages left its DNA dispersed in all present-day people. Meanwhile, researchers reported Thursday (July 30) in the journal Science that the other, a "super-archaic" lineage, dates back nearly 2 million years. "These extinct populations may have lived hundreds of thousands, or even more than a million, years ago, yet traces of their genetic legacy remain preserved in our genomes today," said study co-author Priya Moorjani, a human evolutionary geneticist at the University of California, Berkeley. For more than ten years, scientists have discovered that DNA evidence indicates our species, Homo sapiens, once mated with now-extinct relatives such as Neanderthals and Denisovans. Most of the population not a part of sub-Saharan ancestry living today have nearly 1 per cent to 2.4 per cent Neanderthal ancestry, and Asians and Oceanians (people from the island nations of the Pacific Ocean) harbour approximately 0.1 per cent to 6 per cent Denisovan ancestry.

"Ancient DNA has transformed our understanding of human evolution, but it can only tell us about populations for which DNA has been preserved," Moorjani said. "DNA survives only under very specific conditions — typically in cold, dry environments, which means that much of our evolutionary history, particularly in Africa, other tropical regions, and at very deep timescales, remains inaccessible." Long-extinct ancestors In the new finding, Moorjani and her team members explained that everyone's genome has a record of their ancestry. They also investigated possibilities to uncover signs of "long-extinct ancestors preserved within the genomes of present-day people." They also developed a new technique to scan and compare over 500 complete genomes of present-day humans from around the world. Drawing on this data, researchers reconstructed detailed genealogies for individual segments of each person's genome, building family trees that traced ancestral lineages back through every point of divergence and merging. Their focus centred on ancestors whose genetic makeup differed significantly from modern humans, an indicator that these lineages had branched off from the modern human line long ago. "Most regions of our genome share a common ancestor relatively recently in our evolutionary history," Moorjani said. "Occasionally, however, we find stretches of DNA whose common ancestor lies much farther back in time, indicating they originated from a long-separated human lineage," she added. What sets this method apart from earlier techniques is that it doesn't rely on fossil DNA to detect ancient genetic sequences within modern-human genomes. According to Moorjani, scientists no longer need to depend on rare, well-preserved fossils to learn about extinct human populations. Instead, the genomes of people alive today carry remnants of these ancient ancestors, and genealogical analysis can help uncover that concealed history.

Beyond confirming known lineages, the method also revealed previously undocumented cases of interbreeding with extinct groups. Notably, the researchers found DNA from one "ghost lineage" present across all modern humans — evidence suggesting this group interbred with modern humans in Africa more than 50,000 years ago, predating the most recent wave of Homo sapiens migration out of Africa and into the rest of the world. "Previous publications suggested that there might be ghost ancestry, ancestry from unknown archaic lineages in modern humans, but they hadn't concluded whether this unknown ancestry is present only in Africans or not, and when this introgression event happened," study co-author Yulin Zhang, a computational biologist at UC Berkeley, said in a statement. "We were actually able to find and map genomic locations in modern humans that are from this ghost lineage and show that this ghost ancestry is in all modern humans, not only in Africans." This new DNA contains around 0.5 per cent to 1 per cent of the genomes of modern humans, comparable to the amount of Neanderthal DNA. It has been estimated that about 800,000 years ago this ghost lineage diverged from the ancestors of modern humans, about the same time Neanderthals and Denisovans did. The possible ghost lineage was found to be Homo heidelbergensis, which lived from about 700,000 to 200,000 years ago in Africa and Europe. "I agree with their speculation that this ghost could have been the species Homo heidelbergensis, which was present in Africa as recently as 300,000 years ago," Chris Stringer, a paleoanthropologist at the Natural History Museum in London who was not involved in the study, said. ‘Super-archaic’ human lineage Researchers also discovered that people from Oceania carry traces of a "super-archaic" human lineage that split from modern humans' ancestors roughly 1.8 million years ago, well before the common ancestor of modern humans, Neanderthals, and Denisovans emerged. This ancient DNA accounted for approximately 0.002% of the Oceanian genomes studied and was found embedded within regions of Denisovan ancestry, indicating it likely entered modern humans through interbreeding with Denisovans. Fernando Villanea, a population geneticist at the University of Colorado Boulder uninvolved in the study, suggested the DNA's age points to Homo erectus as its likely original source, passed first into Denisovans and then into modern humans. This theory gains support from Yunxian skull fossils in China, which share certain features with Denisovan remains, though limited H. erectus genetic material has been analysed so far. "We see hybridisation being a common trait in the evolution of many other species, and these findings help us reframe our scientific thinking away from a mentality of human exceptionalism," Villanea said. According to Villanea, these findings underscore that modern humans descend from multiple ancient species, making hybridisation the norm rather than the exception. These newly identified DNA segments cluster most densely in genome regions tied to immune function and metabolism, a pattern Moorjani says reflects how adapting to new pathogens and food sources has consistently driven human evolutionary pressure.

<p>For over a decade, DNA evidence has shown Homo sapiens once mated with extinct relatives like Neanderthals and Denisovans. Most non-sub-Saharan populations carry 1-2.4% Neanderthal ancestry, while Asians and Oceanians harbour roughly 0.1-6% Denisovan ancestry.</p>

Pacific waters driving the El Nino have never been this warm this early, he said, with a new forecast by the World Meteorological Organisation (WMO) finding sea-surface temperatures now averaging 3C (5.4F) above normal.

A strengthening El Nino that could shatter all-time records is "adding fuel to a planet already on fire" and pushing the world into "uncharted territory," UN Secretary-General Antonio Guterres warned Friday. "Two months ago, I warned that El Nino was arriving on our doorstep," Guterres told the world body. "Now it is inside the house -- and turning up the heat." The El Nino weather pattern warms surface temperatures in the central and eastern equatorial Pacific Ocean, triggering worldwide changes in winds, atmospheric pressure and rainfall patterns, and pushing warmer overall global temperatures. Human-caused climate change can amplify El Nino's impacts because a warmer ocean and atmosphere increase the availability of energy and moisture for extreme weather events, such as heat waves and heavy rainfall. "We have already endured a summer of extremes -- record-shattering heat domes; apocalyptic wildfires raging in Spain, France and far beyond; thousands of lives lost in the scorching conditions," said Guterres. "But according to the latest science, this is only a warm-up act." Pacific waters driving the El Nino have never been this warm this early, he said, with a new forecast by the World Meteorological Organisation (WMO) finding sea-surface temperatures now averaging 3C (5.4F) above normal. The WMO's outlook shows that through October, nearly every land mass on Earth is expected to be hotter than normal. "Taken together, that risks shattering every seasonal record -- and driving even more severe effects worldwide," said Guterres. "We are in uncharted territory." The risks go beyond heat alone, he added. India's monsoon is running well below average, while hotter and drier conditions are forecast from Central America and the Caribbean to parts of South America, South Asia, the Southwest Pacific, Europe and Africa. "The verdict is clear: the climate crisis is in overdrive," said Guterres, outlining action required on four fronts. First, protect people from heat with city- and country-wide heat plans and early warning systems, including expanded access to sustainable cooling. Second, make work safer, with governments setting heat standards so vulnerable workers — in the garment industry, for example — aren't risking their lives. Third, build protection from extreme heat into the design of cities, homes, schools and hospitals, and factor it into plans and budgets. Fourth and most fundamentally, "the world must stop fueling the crisis," said Guterres, and roll back fossil fuels that are driving planet-wide heating rather than treating each disaster as an isolated tragedy.

Researchers at Israel's Weizmann Institute of Science have found that Viagra, may help slow cancer spread by blocking cancer cells' access to cholesterol. While the findings are promising, scientists stress the drug is not yet a proven cancer treatment and clinical trials are still needed.

The little blue pill that revolutionised the treatment of erectile dysfunction may have another unexpected role, this time in the fight against cancer. Researchers at Israel's Weizmann Institute of Science have found evidence suggesting that sildenafil, the active ingredient in Viagra, could help slow the spread of cancer by blocking a newly identified biological pathway involved in metastasis. The findings, published in the journal Cancer Research, suggest the decades-old drug may limit cancer cells' ability to use cholesterol, a key ingredient they need to spread to other parts of the body.

Sildenafil was originally developed to improve blood flow before becoming widely known as a treatment for erectile dysfunction. Now, scientists say the same blood vessel-dilating properties may interfere with the way cancer cells access cholesterol. According to the researchers, cholesterol is a crucial building block for cell membranes. Cancer cells that break away from a primary tumour and spread to distant organs rely heavily on cholesterol to survive and establish new tumours.
