Novartis said Sept. 1 that two Phase III trials of its experimental pill remibrutinib met their primary goal in relapsing multiple sclerosis, reducing the annualized relapse rate compared with…

Engineers have sent data out of a mock brain implant as an electrical current through body tissue, with no wire and no antenna. They tested the link inside a human cadaveric head specimen. The system…

A team led by the University of Texas at Arlington has measured the speed of air moving through a hypersonic ground-test facility by tagging the air's own nitrogen molecules with a laser pulse and…

The XENON Collaboration reports that it has measured low-energy neutrinos from the Sun, using a detector built to search for dark matter. The result rejects the background-only hypothesis at a…

Researchers at Pesticide Action Network organizations estimate that 402 million to 433 million cases of unintentional acute pesticide poisoning (sudden poisonings that were not deliberate) occur…

Say it out loud and something shifts. Naming a feeling ("I'm sad," "I'm anxious") is one of the few pieces of folk psychology to survive contact with a brain scanner: label the emotion, and the…
