A new study tracking 13 astronauts suggests that the human heart may be surprisingly well equipped for a journey to Mars, especially with regular exercise during spaceflight. Researchers found that astronauts' hearts adapted to months of ...

Scientists have turned blood cells from an 80-year-old into neural stem cells with a molecular age of less than 20, effectively reversing more than 60 years of cellular aging in the laboratory. The discovery offers a new way to investigate how cells ...

NASA's Perseverance rover has shattered a historic space exploration record, traveling farther across another world than any vehicle before it. Its advanced self-driving system helped it surpass Opportunity's 28.06-mile record in just five and a half ...

A decades-long mystery beneath the North Sea has finally been solved. Scientists have confirmed that the Silverpit Crater, buried 700 meters below the seabed, was created when a 160-meter-wide asteroid struck Earth roughly 43 to 46 million years ago. ...

Deep inside a high-altitude Chinese cave, scientists discovered a ghostly, eyeless freshwater snail that has evolved to live entirely in darkness, marking the first recorded discovery of its kind in China. Named after a faceless mythical creature, .. ...

Scientists have uncovered a surprising reason why statins, the widely prescribed cholesterol-lowering drugs that help prevent heart attacks and strokes, can sometimes cause muscle pain, weakness, and even severe muscle damage. Using advanced imaging ...

A new study reveals that improved hurricane forecast graphics may help people identify threatened areas without making them more likely to recognize the danger or take protective action. Researchers also found that a widespread misunderstanding of .. ...

Scientists have achieved a major breakthrough in understanding the Universe's earliest moments, measuring the amount of helium formed in the first five minutes after the Big Bang with unprecedented precision. Using one of the world's most powerful .. ...

Scientists have identified the "fattest" belemnite ever discovered, a bizarre, barrel-shaped squid relative that lived in Wyoming's ancient seas 160 million years ago. The exceptionally rare fossils reveal a creature unlike anything previously known, ...

The aging brain may be undergoing a remarkable transformation rather than simply losing its abilities, shifting its focus from remembering details to understanding the bigger picture. Scientists suggest this change could be an evolutionary adaptation ...
