Flightless Jurassic bird was like a carnivorous pheasant with killer claws
Illustration of the flightless Jurassic bird Yuezhuornis yangyuanensis, which had features of both birds and dinosaurs. (Image credit: Mr. Chung-Tat Cheung)Paleontologists in China have discovered a small Jurassic bird that was likely a land-based predator — like a carnivorous pheasant with killer claws. It had some features of birds and others of dinosaurs, suggesting that the earliest birds had a greater diversity of lifestyles than previously recognized.Jurassic birds first emerged 150 million to 148 million years ago, and fossils of them are rare, so experts are just starting to understand how early birds diversified and evolved the ability to fly. The researchers discovered the newly id...

One of America's biggest meteor craters is 100 million years younger than we thought — and coincided with a global extinction event
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...

Scientists reveal why some workout recovery tricks can backfire
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.

Cornell scientists identify rare human genetic disorder in two unusually long-legged cats
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.

The secret to easier exercise as an adult may start in childhood
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.

Children's mental health struggles may expose parents to stigma tied to parenting ideals
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.

Scientists may have overlooked a hidden Alzheimer's culprit for decades
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.

Scientists may have finally solved the mystery of the Moon’s two faces
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 discover how harmful “zombie cells” hide from the immune system
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.

Teenager's rare autoimmune disorder caused her to hallucinate a flying green dinosaur
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...
