Life may have started in sticky, rock-hugging gels rather than inside cells. Researchers suggest these primitive, biofilm-like materials could trap and concentrate molecules, giving early chemistry a protected space to grow more complex. Within these ...

For millions of years, a frozen wanderer drifted between the stars before slipping into our solar system as 3I/ATLAS--only the third known interstellar comet ever spotted. When scientists turned NASA's Swift Observatory toward it, they caught the ...

Avian malaria is spreading across Hawaii in a way scientists didn't fully grasp until now: nearly every forest bird species can help keep the disease alive. Researchers found the parasite at 63 of 64 sites statewide, revealing that both native ...

A distant star system with four super-sized gas giants has revealed a surprise. Thanks to JWST's powerful vision, astronomers detected sulfur in their atmospheres -- a chemical clue that they formed like Jupiter, by slowly building solid cores. That ...

Depression in older adults may sometimes signal the early stages of Parkinson's disease or Lewy body dementia. Researchers found that depression often appears years before diagnosis and remains elevated long afterward, unlike in other chronic ...

Your cat's purr may say more about who they are than their meow ever could. Scientists discovered that purrs are stable and uniquely identifiable, while meows change dramatically depending on context. Domestic cats, in particular, have evolved highly ...

Hundreds of millions of years ago, the first animals to crawl onto land were strict meat-eaters, even as plants had already taken over the landscape. Now scientists have uncovered a 307-million-year-old fossil that rewrites that story: one of the ...

Blood vessels twist, branch, narrow, and balloon in ways that dramatically affect how blood flows -- but most lab models have long treated them like straight pipes. Researchers at Texas A&M have now built a new kind of "vessel-chip" that mirrors the ...

Why does the same virus barely faze one person while sending another to the hospital? New research shows the answer lies in a molecular record etched into our immune cells by both our genes and our life experiences. Scientists at the Salk Institute . ...

A bonobo named Kanzi surprised scientists by successfully playing along in pretend tea party experiments, tracking imaginary juice and grapes as if they were real. He consistently pointed to the correct locations of pretend items, while still ...
