Plague was already a deadly killer 5,500 years ago, long before cities, farming, or the rat-infested conditions usually linked to historic outbreaks. By analyzing ancient DNA from hunter-gatherer cemeteries in Siberia, researchers discovered early .. ...

A new theory suggests the universe is constantly recording its own history in the fabric of spacetime. If correct, this cosmic memory could help solve some of the biggest puzzles in physics, from black holes to dark matter and the universe's ultimate ...

A new study from Northern Arizona University is raising red flags about a widely used global emissions database from Climate TRACE, a consortium co-founded by Al Gore. Researchers found that the database may be dramatically undercounting carbon ...

A major study of Australian native bees found that stem-nesting species may be the first to feel the impact of climate change. Unlike bees that nest underground, they have few ways to escape dangerous heat. Researchers also discovered that tropical . ...

A major study of more than 112,000 people found that eating foods containing common preservatives may be linked to a higher risk of high blood pressure and heart-related diseases. Researchers tracked participants for up to eight years and discovered ...

Scientists have taken a surprising step toward unlocking regeneration in mammals, showing that the ability to rebuild complex body parts may not be lost after all--it may simply be switched off. Using a two-stage treatment, researchers redirected the ...

A Rutgers study suggests GLP-1 drugs such as Ozempic and Wegovy may weaken the link between impulsive tendencies and violent behavior. The surprising finding hints that these medications could affect how people act on impulses, though researchers ...

Scientists have discovered a new Amazonian spider with an astonishing disguise: it looks like a parasitic fungus. The species, Taczanowskia waska, mimics both the appearance and behavior of the fungus, helping it stay hidden from predators and ...

Scientists have digitally preserved the world's most endangered marine mammal by creating highly detailed 3D models of a vaquita skeleton using advanced imaging technology. The virtual archive provides an unprecedented look at the species and could . ...

Exposure to a common plastic chemical before and shortly after birth may have lasting effects on behavior. Researchers found that male rats exposed early in life to DEHP--a plasticizer used in products ranging from medical devices to toys--showed ...
