Scientists have uncovered a surprising genetic shift that may explain how animals with backbones--from fish and frogs to humans--became so complex. By comparing sea squirts, lampreys, and frogs, researchers found that key genes controlling cell ...

Plants make chemical weapons to protect themselves, and many of these compounds have become vital to human medicine. Researchers found that one powerful plant chemical is produced using a gene that looks surprisingly bacterial. This suggests plants . ...

A newly identified tiny dinosaur, Foskeia pelendonum, is shaking up long-held ideas about how plant-eating dinosaurs evolved. Though fully grown adults were remarkably small and lightweight, their anatomy was anything but simple--featuring a bizarre, ...

Researchers have found that manganese, an abundant and inexpensive metal, can be used to efficiently convert carbon dioxide into formate, a potential hydrogen source for fuel cells. The key was a clever redesign that made the catalyst last far longer ...

Astronomers have produced the most detailed map yet of dark matter, revealing the invisible framework that shaped the Universe long before stars and galaxies formed. Using powerful new observations from NASA's James Webb Space Telescope, the research ...

As we age, our cells don't just wear down--they reorganize. Researchers found that cells actively remodel a key structure called the endoplasmic reticulum, reducing protein-producing regions while preserving fat-related ones. This process, driven by ...

A new brain imaging study reveals that remembering facts and recalling life events activate nearly identical brain networks. Researchers expected clear differences but instead found strong overlap across memory types. The finding challenges decades . ...

Chronic stress can damage the gut's protective lining, triggering inflammation that may worsen depression. New research shows that stress lowers levels of a protein called Reelin, which plays a key role in both gut repair and brain health. Remarkably ...

As demand for critical metals grows, scientists have taken a rare, close look at life on the deep Pacific seabed where mining may soon begin. Over five years and 160 days at sea, researchers documented nearly 800 species, many previously unknown. ...

SAR11 bacteria dominate the world's oceans by being incredibly efficient, shedding genes to survive in nutrient-poor waters. But that extreme streamlining appears to backfire when conditions change. Under stress, many cells keep copying their DNA ...
