“The climate emergency is already here”
One of America's largest meteor craters is around 100 million years younger than scientists thought, which means the ancient impact coincided with — and potentially contributed to — one of the biggest global extinction events in Earth's history, according to a new study.The underground impact structure, known as Ames crater, is located in northern Oklahoma and is named after a small town that sits above the submerged crater. At around 10 miles (16 kilometers) wide, it is the fourth-largest impact structure in the U.S.Ames crater was created when an Eiffel Tower-size space rock slammed into our planet at more than 70,000 mph (110,000 km/h). At the time, the region was covered in a shallow oce...
On November 18, Voyager 1 will reach one light-day from Earth. It’s still finding surprises in interstellar space.
Ice baths, massages, compression garments, and recovery supplements promise faster muscle recovery, but research suggests their benefits are often overstated, and some techniques may even undermine long-term gains. Scientists say the most effective recovery methods are far simpler and cheaper: getting enough sleep, eating well, and giving muscles time to rebuild.
Two unusually long-legged cats have helped scientists uncover the first genetically confirmed cases of Marfan syndrome in domestic felines. Researchers at Cornell University discovered that the brothers carried two altered copies of a gene linked to the rare connective tissue disorder, which can affect the eyes, heart, and blood vessels. Surprisingly, the cats survived into adulthood because their genetic mutation still allowed some normal function.
Retailers have every reason to be interested in AI. A shopping assistant that answers questions at any hour, compares products instantly and offers personalized recommendations sounds like a win for customers and businesses alike.
Exercise during childhood could have a surprising lifelong benefit, potentially making physical activity less exhausting in adulthood. In a study involving guinea fowl, researchers discovered that birds accustomed to carrying weights while growing up could carry those weights as adults without using extra energy, while untrained birds burned 23% more.
Parents of children with mental health problems may experience stigma when the ideals that matter most to being considered a "good parent" are perceived as not being met, according to preliminary research led by Weill Cornell Medicine, Columbia University Vagelos College of Physicians and Surgeons and NewYork-Presbyterian investigators.
For decades, scientists have focused on amyloid beta as a major culprit behind Alzheimer’s disease, spending billions of dollars developing treatments that have often delivered disappointing results. Now, researchers at UC Santa Cruz are drawing attention to a largely overlooked peptide called P3 that could also play a role in the disease. Previously believed to be harmless, P3 can form harmful-looking protein clumps even faster than amyloid beta and may also damage brain cells.
Researchers at New Jersey Institute of Technology (NJIT) have found that a largely overlooked class of "forever chemicals" is widespread in New Jersey drinking water and commercially available bottled beverages, raising new questions about how these persistent contaminants are monitored and potentially introduced into everyday products.
Quantum networks are systems that connect different users or devices using principles of quantum mechanics. In the future, these networks could help improve the security of communications.
Evidence for this possible super-Earth has been lurking for years in NASA data. Pavel Rabtsevich found it—with a little help from AI
Scientists may have solved a long-standing mystery about why the Moon’s two sides are so different, using samples collected from its farside for the first time. Their findings suggest that uneven heating from Earth's gravitational pull drove enormous flows of ancient magma, creating the dramatically different lunar landscapes we see today.
Scientists have discovered a protein that may help harmful aging cells hide from the immune system, allowing them to accumulate and fuel age-related health problems. Blocking the protein in mice reduced these cells and inflammation while improving blood sugar regulation and strength, offering a promising new direction for anti-aging research.
The patient: A 16-year-old girl in CaliforniaThe symptoms: The teenager was referred to an emergency department because she was having hallucinations, including seeing a flying green dinosaur and hearing voices telling her to hurt others. She also had a sense that she was being followed.In the emergency room, she was trembling and sweating and had a racing pulse and shallow, fast breathing. She did not have a fever, although she did have one at the hospital that had referred her.During her conversations with ER clinicians, the teen reacted to the vision of the dinosaur as though the creature were present in the room. She reported that she had experienced these hallucinations since seventh gr...

The data behind Blue Zones might not be that strong
Deforestation slowed worldwide last year, but the improvement is unlikely to last as the situation deteriorates in Central Africa and an exceptionally strong El Niño weather pattern intensifies, a new study said on Wednesday.
Until now, the alien white-hot worlds of exoplanets have been depicted as circular, but new research has revealed the true shape of their atmospheres to be a deformed sphere rather than a perfect circle.
The two warmest time periods on Earth in the past 140 million years drove both mass extinctions and explosions in plant diversity, according to researchers in Australia and Austria who say this could explain how flowering plants became dominant among land plants. The study, published in Nature Plants, examined fossilized pollen and spores to show that the mid-Cretaceous and early Cenozoic periods of extreme global warmth were central to plant evolution. This applies not only to flowering plants, but also to the other main land plant groups.
Since June, more than 300 southern right whale (Eubalaena australis) calves have died in Argentine Patagonia, in what scientists describe as an "exceptional" die-off. The preliminary figure already far exceeds the previous annual record set in 2012, when 113 southern right whale calves died — the highest number ever documented for the species, both locally and globally.Now, scientists are racing to figure out exactly what's causing the record-breaking die-off. Laboratory analyses of specimens that died this year tested positive for the pathogenic bacterium Erysipelothrix rhusiopathiae, environmental authorities in Chubut province told Live Science. E. rhusiopathiae was first identified in so...
A massive prehistoric snake discovered in India may have rivaled the largest snake ever known. Called Vasuki indicus, the 47-million-year-old giant could have reached up to 50 feet long, making it comparable to the legendary Titanoboa. Scientists believe its enormous body made it a slow-moving ambush predator, similar to a modern anaconda.
A promising new treatment for knee arthritis uses tiny, dissolvable particles to block abnormal blood vessels, easing inflammation and pain without joint replacement surgery. In a study of 194 patients, 80% experienced clinically meaningful pain relief lasting at least 12 months.
