Lowering salt in everyday foods could quietly save lives. Researchers found that modest sodium reductions in bread, packaged foods, and takeout meals could significantly reduce heart disease and stroke rates in France and the U.K. The key advantage . ...

NASA's Perseverance rover has just made history by driving across Mars using routes planned by artificial intelligence instead of human operators. A vision-capable AI analyzed the same images and terrain data normally used by rover planners, ...

Termites did not evolve complex societies by adding new genetic features. Instead, scientists found that they became more social by shedding genes tied to competition and independence. A shift to monogamy removed the need for sperm competition, while ...

Archaeologists in central China have uncovered evidence that early humans were far more inventive than long assumed. Excavations at the Xigou site reveal advanced stone tools, including the earliest known examples of tools fitted with handles in East ...

People who naturally stay up late may be putting their hearts under added strain as they age. A large study tracking more than 300,000 adults found that middle-aged and older night owls had poorer overall heart health and a higher risk of heart ...

Men start developing heart disease earlier than women, with risks rising faster beginning around age 35, according to long-term research. The difference is driven mainly by coronary heart disease, not stroke or heart failure. Traditional risk factors ...

A new drug developed by Australian researchers has shown promising results in reducing sepsis in a Phase II clinical trial involving 180 patients. The carbohydrate-based treatment works by calming a dangerous immune reaction that can cause organ ...

On a remote Alaskan island, gray wolves are rewriting the rulebook by hunting sea otters -- a behavior few scientists ever expected to see. Researchers are now uncovering how these coastal wolves adapted to marine hunting, what it means for land-sea ...

Researchers have found a way to make ordinary aluminum tubes float indefinitely, even when submerged for long periods or punched full of holes. By engineering the metal's surface to repel water, the tubes trap air inside and refuse to sink, even in . ...

Researchers have discovered how pancreatic cancer reprograms its surroundings to spread quickly and stealthily. By using a protein called periostin, the tumor remodels nearby tissue and invades nerves, which helps cancer cells travel and form ...
