Where your body stores fat may matter just as much as how much you carry--especially for your brain. Using advanced MRI scans and data from nearly 26,000 people, researchers identified two surprising fat patterns tied to faster brain aging, cognitive ...

A repeating fast radio burst has just given up one of its biggest secrets. Long-term observations revealed a rare signal flare caused by plasma likely ejected from a nearby companion star. This shows the burst source isn't alone, but part of a binary ...

For the first time, astronomers have captured radio signals from a rare exploding star, exposing what happened in the years leading up to its death. The radio waves reveal that the star violently shed huge amounts of material shortly before it ...

What looked like a pearl necklace on a tiny spider turned out to be parasitic mite larvae. Scientists identified the mites as a new species, marking the first record of its family in Brazil. The larvae attach to juvenile spiders and feed on lymph ...

A common parasite long thought to lie dormant is actually much more active and complex. Researchers found that Toxoplasma gondii cysts contain multiple parasite subtypes, not just one sleeping form. Some are primed to reactivate and cause disease, .. ...

Researchers have discovered a biological switch that explains why movement keeps bones strong. The protein senses physical activity and pushes bone marrow stem cells to build bone instead of storing fat, slowing age-related bone loss. By targeting .. ...

Bright white rocks spotted by NASA's Perseverance rover are rewriting what we thought we knew about ancient Mars. These aluminum-rich clays, called kaolinite, usually form on Earth only after millions of years of heavy rainfall in warm, humid ...

The Ediacara Biota are some of the strangest fossils ever found--soft-bodied organisms preserved in remarkable detail where preservation shouldn't be possible. Scientists now think their survival in sandstone came from unusual ancient seawater ...

Scientists have found compelling new evidence that humans, not glaciers, brought Stonehenge's bluestones to the site. Using advanced mineral analysis, researchers searched nearby river sediments for signs glaciers once passed through the area--and .. ...

Physicists have discovered that hidden magnetic order plays a key role in the pseudogap, a puzzling state of matter that appears just before certain materials become superconductors. Using an ultra-cold quantum simulator, the team found that even ...
