A crescent-shaped crater in Northeast China holds the record as the largest impact crater on Earth that formed in the last 100,000 years. Prior to 2020, the only other impact crater ever discovered in China was found in Xiuyan county of the coastal province of Liaoning, according to a statement from the NASA Earth Observatory. Then,

Rising global temperatures bring dire threats, such as floods, heat-related injuries, water scarcity, and hunger, making up to 3.6 billion people – nearly half of the world’s population – highly vulnerable to climate change. That’s according to a major report, released Monday, from the Intergovernmental Panel on Climate Change – a UN body that recruits
A signal interpreted as the first light illuminating the Universe may not be from the far reaches of the Universe after all, a new study has found. In fact, it may not even be from space. Far from being a problem, however, this new finding may just set the Universe to rights. The signal, described
The Red Sea has been hiding powerful geological forces that could put communities on the coast of Egypt and Saudi Arabia at risk. The thought hit Sam Purkis like a wave, as he gazed out the window of a submarine 900 meters deep (3,000 feet) in Tiran Strait. There, in the light of the vehicle’s
Hidden turbulent motion that takes place inside the atmosphere of the Sun can be accurately predicted by a newly developed neural network. Fed only temperature and vertical motion data collected from the surface of the solar photosphere, the AI model could correctly identify turbulent horizontal motion below the surface. This could help us to better
It’s been nearly 80 years since two nuclear bombs were detonated over the Japanese cities of Hiroshima and Nagasaki, killing at least 129,000 people, and causing devastating, long-term health effects. To date, those are the only instances of nuclear weapons being used for warfare, but the reality is there are roughly 12,700 warheads remaining in the
The largest plane in the world – Ukraine’s Antonov-225 cargo plane – was destroyed by Russian strikes outside Kyiv on the fourth day of Moscow’s invasion, Ukraine’s state-owned Ukroboronprom group said Sunday. “Russian invaders destroyed the flagship of the Ukrainian aviation, the AN-225” at the Antonov airport in Gostomel near Kyiv, the group said in
Nearly 200 nations approved a major UN climate change report detailing the accelerating impacts of global warming on Sunday, at the end of a sometimes fraught two-week meeting overshadowed by Russia’s invasion of Ukraine. The Intergovernmental Panel on Climate Change (IPCC) confirmed that debates had concluded over the report’s crucial “Summary for Policymakers”, a 40-page
We humans are versatile and accomplished navigators, but insects might have navigation skills that are even better. For them, it’s literally a matter of life and death – and that’s why we decided to freeze some ants and beetles (don’t worry, they still survived) to learn more about how they remember their way home after
An ancient skull uncovered at a 6,000-year-old megalithic monument in Spain still holds signs of what would have been a brutal ear surgery. Archaeologists suspect the patient probably had a double-sided acute middle ear infection, which can cause earaches and fevers. Without treatment, fluid can gather behind the eardrum, possibly causing a visible lump in
Black holes could make a strong case for being the most fascinating phenomena in the whole Universe, and scientists are constantly discovering more about the way that they work and behave – including how they’re created in the first place. Now, a new study of an unusually misaligned one some 10,000 light-years away from Earth
The Curiosity rover took a picture of something pretty enticing this week on the surface of Mars. While the object in question looks like a tiny little flower or maybe even some type of organic feature, the rover team confirmed this object is a mineral formation, with delicate structures that formed by minerals precipitating from water. Curiosity
Microsoft had big plans when it purchased Minecraft, the immensely popular open-world ‘sandbox’ game, back in 2014 for US$2.5 billion. Among them was to invest heavily in an educational revolution – the gamification of learning. It’s not hard to imagine how the logic-based mechanics of Minecraft’s construction system could help teach knowledge and practical skills in fields of
Not all planetary systems are alike. Out there in the big, wide galaxy, a number of different configurations have been spotted, some vastly different from our home system. These include extrasolar planets, or exoplanets, that orbit not one, but two stars, like the fictional Star Wars world of Tatooine. Now, for the first time, astronomers have
The capacity to engage with and comprehend music spans nearly every human society. While other creatures also display musical behaviors (think bird song, humpback whale calls, or bonobo vocalizations), our musical cognition appears to be evolutionary distinct within the animal kingdom. A new study has given us more insight into the brain’s relationship with music, finding that singing
A dance of death is taking place at the heart of a galaxy in the distant Universe. Some 10 billion light-years away, two supermassive black holes are locked in an orbit so tight that they will collide with each other and form one much larger black hole in the relatively short time of just 10,000
Russia’s invasion of Ukraine has placed a question mark over the future of the International Space Station, long a symbol of post-Cold War cooperation, where astronauts and cosmonauts proudly live and work side-by-side. The outpost was the subject of a menacing Twitter thread by Russian space agency head Dmitry Rogozin, who warned Thursday that US
The Chernobyl nuclear power plant and its surrounding area are showing increased radiation levels after heavy fighting between Ukrainian and Russian troops in the region, Ukrainian officials said Friday (Feb. 25) Online data from the Chernobyl exclusion zone’s automated radiation-monitoring system shows that gamma radiation has increased 20 times above usual levels at multiple observation points, which officials
Scientists would be able to discover much more about what lies underground if our planet could be sliced open and viewed as a cross-section – but as that’s not really possible, they have to rely on a variety of other methods instead. One new approach has just been proven in the field: A recently developed
A meteor that exploded in the sky over Chelyabinsk, Russia in 2013 could have also been somehow involved in the giant impact that formed the Moon. This tantalizing finding comes thanks to a new way of dating collisions between rocks in space, based on microscopic analysis of minerals within meteorites. Although further investigation is warranted,
In June 2000, two rival groups of researchers shook hands in the shared success of a milestone in biology – the delivery of a rough draft of the human genome. What started with an incomplete map of our chromosomes has since bloomed into a vast trove of individualized sequences from all corners of the globe,
Russian troops have captured Chernobyl‘s former nuclear power after heavy fighting near the Chernobyl exclusion zone, according to an advisor to the Ukrainian presidential office. Ukrainian troops fought with Russian forces, which invaded the region from Belarus and have seized control of the now-defunct power plant, according to Mykhailo Podolyak, an aide to the Ukrainian
The loss of a beloved canine companion is devastating, and new research shows that you might not be the only one feeling it. Any other dogs in your family could also go through mourning, as indicated by their behavior. A survey of 426 multiple-dog owners in Italy revealed that, when one dog in the family
When it comes to longevity and surviving extended amounts of time without food, the Argas brumpti species of African tick is hard to beat, newly published research shows. Observed close-up in the lab over the course of 45 years by entomologist Julian Shepherd from Binghamton University in New York, some of these ticks have survived as
A billion years ago, an absolutely monstrous collision of two clusters of galaxies produced a pair of shock waves of absolutely epic proportions. Today, the structures gleam brightly in radio wavelengths, so huge they could easily engulf the Milky Way galaxy’s estimated 100,000 light-year diameter, stretching up to 6.5 million light-years through intergalactic space. Now,
Fresh water cycles from ocean to air to clouds to rivers and back to the oceans. This constant shuttling can give us the illusion of certainty. Fresh water will always come from the tap. Won’t it? Unfortunately, that’s not guaranteed. Climate change is shifting where the water cycle deposits water on land, with drier areas
Archaeologists deep in the Jordanian desert have discovered a 9,000-year-old ritualistic complex near what is thought to be the earliest known large human-built structure worldwide. The Stone Age shrine site, excavated last year, was used by gazelle hunters and features carved stone figures, an altar and a miniature model of a large-scale hunting trap. The
The Chicxulub asteroid that ended the reign of the dinosaurs is one of the most momentous impact disasters in Earth’s history, and scientists have now identified the time of year when this deadly event took place. New evidence suggests the asteroid hit in the spring for the Northern Hemisphere, which would be fall (or autumn) for
A recently discovered repeating fast radio burst (FRB) named FRB 20200120E is deepening the mystery of these already deeply mysterious space signals. Astronomers have tracked its location to a galaxy 11.7 million light-years away, which makes it the closest known extragalactic fast radio burst, 40 times closer than the next-closest extragalactic signal. But it also
Every summer, as the sea ice surrounding Antarctica retreats, tens of thousands of tourists and scientists flock to the landmass by boat and plane. The remote continent is becoming increasingly accessible – during the 2019-20 season, the number of sightseeing visitors reached 74,000, with the vast majority traveling by ship. Scientific activities on the continent
China’s Yutu-2 mission has made another fascinating discovery on the far side of the Moon. Glistening amid the dry, gray dust, the rover’s panoramic camera picked out two small intact spheres of translucent glass. Such spherules can record information about the Moon’s history, including the composition of its mantle and impact events. Yutu-2 was unable
For over 25 years, a group in Poulton, England has been looking for a lost Cistercian abbey. Instead, over the decades the team has found hundreds of medieval skeletons and well-traveled Roman artifacts. Now, they have discovered what they’re calling “the best preserved picture of late prehistoric life ever found in [North West England]”. Over
A deposit of hundreds of embalming tools uncovered in Abusir, Egypt – probably the largest ever found – offers clues into a lavish funeral that likely took place about 2,600 years ago. The deposit of at least 370 ceramic jars – some of which carried heads to represent sacred animal deities – could provide unprecedented
During low tide on Scotland’s Isle of Skye, a graduate student hunting for dinosaur bones looked down at the coastal rocks and made the discovery of a lifetime: the remains of the largest pterosaur on record from the Jurassic period. Since collecting the specimen in 2017 – an eventful excavation that involved cutting out the
You may already know the legend of King Tutankhamen’s space dagger – an iron weapon forged from the rock of meteorites, and entombed with the ancient Egyptian pharaoh. Now a new study has revealed more details about this most fascinating and mysterious of artifacts. A thorough chemical analysis involving high-resolution photography and X-rays has revealed
A low-lying continent that existed some 40 million years ago and was home to exotic fauna may have “paved the way” for Asian mammals to colonize southern Europe, new research suggests. Wedged between Europe, Africa and Asia, this forgotten continent – which researchers have dubbed “Balkanatolia” – became a gateway between Asia and Europe when
An object 681 million light-years away might look like one glorious, exquisite mess, but there’s a lot more going on that a first glance indicates. The object showcased in a new Hubble image – called IC 2431 – is not one galaxy, but three, coming together in a massive galactic merger that will one day
When we attached tiny, backpack-like tracking devices to five Australian magpies for a pilot study, we didn’t expect to discover an entirely new social behavior rarely seen in birds. Our goal was to learn more about the movement and social dynamics of these highly intelligent birds, and to test these new, durable and reusable devices.
The James Webb Space Telescope (JWST), launched last December, has been slowly powering up its instruments and unfurling its sunshield, and is now in the process of aligning its mirrors in preparation for operation. Within a few months, the most powerful space telescope ever built is going to set its sights on the stars. Astronomers
China on Monday denied responsibility for a rocket set to slam into the Moon, after experts said the piece of space junk likely came from Beijing’s lunar exploration program. Astronomers initially thought the wayward object was a chunk of a SpaceX rocket that blasted off seven years ago and was abandoned in space after completing
A giant exoplanet 855 light-years away is so extreme, it has clouds of vaporized metals and rains liquid rubies and sapphires. That’s the conclusion astronomers have reached after probing its atmosphere – the most detailed such analysis to date, revealing for the first time the conditions and dynamics of the exoplanet’s permanent night side. “Despite
We tend to think of intelligence as something that describes just one individual. But it’s possible to describe all kinds of collectives as intelligent, too – whether we’re talking about social groups of humans, enclaves of insects, or even the mysterious behavior of slime mold and viruses. By extension, could intelligence be observed on a much grander
A global analysis of sea levels over the past 2,000 years has found a rapid rate of increase in line with the Industrial Revolution. By 1863, researchers found the rate of sea level rise had clearly surpassed background variability. Unsurprisingly, it’s around this time that the first hints of ocean warming and glacier melt from
Paleontologists in Argentina have identified a new species of dinosaur which likely had such feeble forearms, it would make Tyrannosaurus rex look like Popeye in comparison. The dinosaur, named Guemesia ochoai and identified from a single skull, is thought to belong to a clade of tiny-armed carnivores known as abelisaurids, which once tramped across Europe, Africa, South
Successfully achieving nuclear fusion holds the promise of delivering a limitless, sustainable source of clean energy, but we can only realize this incredible dream if we can master the complex physics taking place inside the reactor. For decades, scientists have been taking incremental steps towards this goal, but many challenges remain. One of the core
Almost half of Americans morally opposed to abortion would help a friend or family member with arrangements to get one, and a majority would offer emotional support, a new study said Friday. The authors of the paper, which appeared in the journal Science Advances, wrote the finding showed that people are willing to cross ideological
Photosynthesis quite literally changed our world. Plants ‘eating’ sunlight and ‘breathing out’ oxygen transformed Earth’s entire atmosphere into the one we now breathe, and fuel our ecosystems with energy. Now researchers have caught a cunning species of bacteria with stolen photosynthesizing technology. And their molecular, light-eating device is unlike any we’ve ever seen. “The architecture
In the Mediterranean region, the soil is degrading, and land is turning to desert faster than anywhere else in the European Union, according to a new analysis. Experts warn that the combined effects of unsustainable land practices and climate change have depleted a finite resource to a critical point. A recent publication by a European
