Autism diagnoses have risen dramatically as definitions have expanded, but that shift may carry unexpected consequences. A diagnosis can open the door to understanding, treatment, and practical support. But when the same label is used for people with profoundly different abilities and needs, does it still provide enough useful information? Dame Uta Frith, one of […]
Scientists Reprogram How Light Travels in Just 74 Femtoseconds
An ultrathin silicon surface can steer and reshape light in just 74 femtoseconds, opening a path toward a new generation of high-speed optical technology. A pulse of light can cross the width of a human hair in roughly 74 femtoseconds. In that same vanishingly brief interval, a new device developed at the California Institute of […]

Rewriting History: Researchers Uncover a Forgotten Amazon Civilization That May Have Housed 3 Million People
For nearly 1,500 years, the Aquiry civilization shaped southwestern Amazonia, and new research suggests it supported a much larger population than previously believed. Beneath the dense forests of southwestern Amazonia, airborne lasers revealed a landscape covered with geometric earthworks, straight roads, and large ceremonial centers. The remains point to the Aquiry civilization, a multicultural society […]
Why Arthritis Can Come Back Stronger After Cancer Immunotherapy
What if the immune system’s memory of cancer treatment also teaches it how to restart painful arthritis? Researchers at The University of Texas MD Anderson Cancer Center found evidence that inflammatory arthritis triggered by immune checkpoint inhibitors can repeatedly call on the same populations of immune cells. When the arthritis returns, those cells appear to […]

New Research May Change How We Think About Weight Loss Drugs Like Ozempic
Why do drugs like Ozempic produce far greater and more lasting weight loss than older appetite suppressants? Scientists are beginning to uncover an unexpected answer in the brain. Semaglutide, the active ingredient in Ozempic and other GLP-1 medications, may owe part of its remarkable weight loss effects to an unexpected group of brain cells. A […]
Your Teeth May Reveal a Surprising Clue About Pancreatic Cancer Survival
A person’s teeth may hold a surprising clue to how long they survive after pancreatic cancer surgery. In a new study, patients with at least 21 natural teeth survived nearly two years longer, on average, than those with fewer teeth. Researchers suspect that the mouth may preserve signs of inflammation, nutrition, frailty, and other health […]
