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 large laboratory study found that many commonly used sweeteners can directly change the growth of gut bacteria. Researchers identified more than 100 cases in which sweeteners behaved differently when combined with medications, caffeine, or ...

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 .. ...

Researchers have created self-destructing living plastic that uses engineered bacteria to completely break itself down when activated. The material degrades in just six days without creating microplastics, offering a potential new solution for single ...

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 ...

An international study found that finerenone slows kidney function decline and reduces the risk of serious kidney and cardiovascular complications in people with chronic kidney disease who do not have diabetes. The results could open the door to a .. ...

Scientists have identified a hidden feedback loop that may explain how Earth has regulated its climate for tens of millions of years. As sea levels rose and fell, they changed how much phosphate reached the open ocean, affecting marine life and the . ...

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. ...
