Researchers are replacing rigid silicon-based AI hardware with stretchable, neuromorphic electronics that mimic how the brain processes information, opening new possibilities for long-term human-machine integration. Modern artificial intelligence can outperform humans in tasks ranging from image recognition to medical data analysis, but there is one environment where today’s hardware still struggles: the human body. The [...]

Silphium was an extinct Libyan plant renowned for contraception, medicine, and trade. Its disappearance remains a historical mystery, and scientists continue searching for surviving descendants. Roman leader Julius Caesar is said to have kept a stock of it in the treasury. Ancient writer Pliny the Elder says Rome’s Emperor Nero owned the last stalk of [...]

A new AI system can suggest just a few targeted ingredient swaps that make meals healthier and cheaper without dramatically changing what people already eat. Researchers at the University of California, Davis, have developed an artificial intelligence system that can make meals healthier and more affordable by recommending as few as one to three ingredient [...]

A new study suggests that subtle changes in the brain’s immune cells could help explain why some people remain mentally sharp despite Alzheimer’s pathology. For decades, Alzheimer’s research has focused on the buildup of amyloid plaques and tau tangles, the two hallmark features of the disease. Yet a puzzling reality has continued to challenge scientists: [...]

A distant quasar has revealed one of the most extreme ultraviolet outflows ever observed, providing new clues about the powerful interactions between supermassive black holes and their host galaxies. A supermassive black hole more than a billion times the mass of the Sun is blasting gas through space at such extraordinary speeds that astronomers are [...]

An interstellar comet just revealed hidden methane and chemical clues from another star system. NASA’s James Webb Space Telescope has achieved another milestone by capturing the first mid-infrared chemical fingerprint of an interstellar object. The observations focused on comet 3I/ATLAS, a rare visitor from beyond our solar system, and the findings have been published in [...]

Scientists found that aging may begin with a hidden cellular remodel that could help drive disease later in life. Thanks to advances in public health, people are living longer than ever before. However, many of those extra years are accompanied by chronic illnesses rather than good health. Aging is a normal part of life, but [...]

A kidney test result that appears perfectly normal may still reveal hidden danger, according to a major new study involving more than a million adults. Even small differences in kidney function, including values that still fall within the normal range, may reveal who is at greater risk of developing chronic kidney disease. That is the [...]

Scientists discovered a hidden gut-brain network that can change cravings when the body needs more protein. The body has a remarkable ability to recognize when it is missing important nutrients and adjust behavior accordingly. New research shows that the gut plays a much larger role in this process than previously understood, actively detecting protein shortages [...]
