Researchers uncovered a 2.75-2.44 million-year-old site in Kenya showing that early humans maintained stone tool traditions for nearly 300,000 years despite extreme climate swings. The tools, remarkably consistent across generations, helped our ...

Beneath the ocean's surface, bacteria have evolved specialized enzymes that can digest PET plastic, the material used in bottles and clothes. Researchers at KAUST discovered that a unique molecular signature distinguishes enzymes capable of ...

A collaboration between Brazilian and German researchers has led to a sunflower-based meat substitute that's high in protein and minerals. The new ingredient, made from refined sunflower flour, delivers excellent nutritional value and a mild flavor. ...

Long ago, some saltwater fish adapted to freshwater -- and in doing so, developed an extraordinary sense of hearing rivaling our own. By examining a 67-million-year-old fossil, researchers from UC Berkeley discovered that these "otophysan" fish didn ...

Okayama scientists have crafted a new wine grape, Muscat Shiragai, merging the wild Shiraga and Muscat of Alexandria. The variety is part of a larger collaboration between academia, industry, and local government to boost regional identity through .. ...

In the Gulf of California, a pod of orcas known as Moctezuma's pod has developed a chillingly precise technique for hunting young great white sharks -- flipping them upside down to paralyze and extract their nutrient-rich livers. The behavior, filmed ...

Researchers at UC San Diego have figured out how to get bacteria to produce xanthommatin, the pigment that lets octopuses and squids camouflage. By linking the pigment's production to bacterial survival, they created a self-sustaining system that ...

Scientists uncovered how the amino acid leucine enhances mitochondrial efficiency by preserving crucial proteins that drive energy production. By downregulating the protein SEL1L, leucine prevents unnecessary degradation and strengthens the cell's .. ...

Penn State scientists uncovered an ancient bacterial defense where dormant viral DNA helps bacteria fight new viral threats. The enzyme PinQ flips bacterial genes to create protective proteins that block infection. Understanding this mechanism could ...

Bamboo tissue paper, often marketed as an eco-friendly alternative, may not be as green as consumers think. Researchers at NC State University found that while bamboo fibers themselves are not more polluting than wood, China's coal-dependent energy . ...
