A new blood test may reveal Crohn's disease years before symptoms begin. The test detects an unusual immune response to gut bacteria in people who later develop the condition. By studying healthy relatives of Crohn's patients, researchers identified ...

A new study reveals that super agers over 80 have a distinct genetic edge. They are much less likely to carry the gene most associated with Alzheimer's risk, even when compared with other healthy seniors. Researchers also found higher levels of a ...

Scientists found that nasal cells act as a first line of defense against the common cold, working together to block rhinovirus soon after infection. A fast antiviral response can stop the virus before symptoms appear. If that response is weakened or ...

Scientists studying genetic data from over a quarter million people have uncovered new clues about what controls how fast the gut moves. They identified multiple DNA regions linked to bowel movement frequency, confirming known gut pathways and ...

Blockchain could make smart devices far more secure, but sluggish data sharing has held it back. Researchers found that messy network connections cause massive slowdowns by flooding systems with duplicate data. Their new "Dual Perigee" method lets .. ...

NASA astronaut Suni Williams has retired after 27 years of service and a career defined by endurance, leadership, and firsts in space. She spent 608 days in orbit, completed nine spacewalks, and twice commanded the International Space Station. ...

A long-standing law of thermodynamics turns out to have a loophole at the smallest scales. Researchers have shown that quantum engines made of correlated particles can exceed the traditional efficiency limit set by Carnot nearly 200 years ago. By ...

Fungal infections are becoming deadlier as drug resistance spreads and treatment options stall. Researchers at McMaster University discovered that a molecule called butyrolactol A can dramatically weaken dangerous fungi, allowing existing antifungal ...

New research suggests that consistent aerobic exercise can help keep your brain biologically younger. Adults who exercised regularly for a year showed brains that appeared nearly a year younger than those who didn't change their habits. The study ...

Scientists are learning how to temporarily reshape materials by nudging their internal quantum rhythms instead of blasting them with extreme lasers. By harnessing excitons, short-lived energy pairs that naturally form inside semiconductors, ...
