Earth is quietly collecting radioactive debris from an ancient stellar explosion as our Solar System drifts through a giant cloud of gas and dust between the stars. Scientists analyzing Antarctic ice up to 80,000 years old discovered traces of iron . ...

For nearly 100 years, reinforced rubber has powered everything from car tires to airplanes, yet scientists never fully understood why adding tiny particles of carbon black made rubber so incredibly strong. Now, researchers at the University of South ...

A medieval monk may have beaten Edmond Halley to one of astronomy's greatest discoveries by nearly 700 years. Researchers say Eilmer of Malmesbury recognized that the blazing comet seen in 1066 was the same one he had witnessed in 989. At the time, . ...

Humans may have returned to Britain far earlier than scientists once believed -- not long after the last ice sheet began retreating. New evidence suggests people were already moving into the British Isles around 15,200 years ago, tracking herds of .. ...

Scientists in Japan have developed a new way to instantly detect elusive quantum "W states," a major milestone for quantum technology. The breakthrough could help unlock faster quantum communication, teleportation, and powerful new computing systems.

Cacti may look like slow, stubborn desert survivors, but they're actually evolving at lightning speed. Scientists studying more than 750 cactus species discovered that what really drives the explosion of new cactus species isn't flower size or ...

The little pauses, "ums," and moments when you struggle to find the right word may reveal far more about your brain than anyone realized. Researchers discovered that everyday speech patterns are closely tied to executive function -- the mental system ...

Scientists at UBC Okanagan have uncovered how plants produce mitraphylline, a rare natural compound with promising anti cancer potential. The team identified two enzymes that work together to build the molecule's unusual twisted structure, solving a ...

Scientists at the University of Maryland, Baltimore County, have uncovered a crucial trick used by enteroviruses--the group behind diseases like polio, myocarditis, encephalitis, and even the common cold--to reproduce inside human cells. The team ...

Researchers found a new way to kill harmful "zombie" cells that linger after chemotherapy and help cancers become more aggressive. These senescent cells survive by relying on a protective protein called GPX4, even while sitting on the edge of a ...
