Scientists say new technologies have reopened the debate over whether Mars could someday be terraformed, turning a once impossible idea into a serious research topic. Before anyone tries to reshape the Red Planet, though, researchers say we must ...

A team of mathematicians used whimsical "silly sprinklers" to solve a physics mystery that has puzzled scientists for decades. Their experiments showed that the rotation of both normal and reverse sprinklers is driven by the momentum of flowing water ...

Tiny plastic particles in drinking water may be doing more than contaminating the environment. New research suggests nanoplastics can actually help harmful bacteria survive by strengthening the slimy biofilms they form inside water systems. These ...

A study of 225 newborns suggests prenatal estrogen may have played a role in the evolution of larger human brains. Boys with finger-length patterns linked to higher estrogen exposure before birth tended to have larger head circumferences, which are . ...

A major DNA study has rewritten the koala's evolutionary story, revealing that the species suffered a dramatic population collapse about 100,000 years ago, long before humans arrived in Australia. By calculating the koala's mutation rate for the ...

A new particle detector called PLATON could replace millions of tiny detector components with a single block of light-producing material. Using a light-field camera, highly sensitive photon sensors, and AI, it reconstructs particle paths in fast, ...

A drug originally developed for spinal cord injury may offer a fresh approach to treating Alzheimer's disease. In mouse studies, KCL-286 repaired dangerous DNA damage, reduced inflammation, and targeted multiple disease-related pathways instead of .. ...

A new experimental treatment may have found a way to outsmart glioblastoma's toughest defense: the blood-brain barrier. Researchers used sugar-coated nanoparticles to ferry genetic instructions that restore a key tumor-suppressing protein directly .. ...

An ancient sea worm may hold the secret to a whole new category of natural materials. Its jaws combine proteins and metal ions in a way that gives them metal-like strength and unusual mechanical behavior, yet they still differ from traditional metals ...

A distant Sun-like star appears to have devoured one of its planets, leaving behind a surprising chemical fingerprint. Researchers found an unusually high concentration of lithium, a strong sign that planetary material was mixed into the star. ...
