To rapidly transmit electrical signals in the brain, the long nerve fibers are insulated by specialized cells called oligodendrocytes. These cells also respond to the electrical signals of active nerve fibers and provide them with energy on demand, as researchers have discovered. If this process, regulated by potassium, is disabled in mice, the nerve fibers are severely damaged as the animals age -- resembling the defects of neurodegenerative diseases.

Google today introduced a new selfie sign-in option for Google Account recovery. It offers an alternative way for Google users to access their accounts alongside passkeys, recovery contacts, and other entry methods. To create a selfie video, you look at your device's camera and then follow Google's instructions to complete a series of head movements to capture multiple angles. The video is saved to your account and can be used... Read more ›

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. Careful comparisons with dozens of similar stars confirmed the signal is highly unusual, and scientists think a massive brown dwarf companion may have helped send the planet on its fatal plunge.

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 amount of carbon buried beneath the seafloor. That burial removed carbon dioxide from the atmosphere, helping cool the planet. Read more ›

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 much-needed new treatment option for the majority of CKD patients who have long had limited choices. Read more ›

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. Researchers believe these "bio-metals" could open new directions in materials science while revealing just how sophisticated nature's designs can be. Read more ›

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 into brain cancer cells. In mouse studies, the therapy increased median survival by 50% while shrinking tumors without noticeable damage to other organs. Read more ›

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 focusing on just amyloid or tau. Since it has already cleared an initial human safety trial, researchers believe it could move more quickly into Alzheimer’s clinical testing. Read more ›

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, detailed 3D. Simulations suggest it could match or surpass today’s best detectors while being far easier to scale. The technology may also lead to sharper PET medical scans. Read more ›

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 flavorings. The combination of isosteviol and the antidepressant duloxetine was especially disruptive, reducing beneficial bacteria and overall microbial diversity. Read more ›

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, not by the outside water flow or other long-standing theories. The results finally provide a clear answer to Feynman’s famous sprinkler problem. They could also help engineers design more efficient fluid-powered... Read more ›
