gizmodo.com Gayoung Lee 2025-08-17 20:00:07

Scientists equipped with giant lasers have blown up gold at SLAC National Accelerator Laboratory, heating it to 14 times its boiling point. For a chilling second, they thought they broke physics, but they fortunately did no such thing. That said, they broke something else: a decades-long model in physical chemistry having to do with the fundamental properties of matter. In an experiment presented today in Nature, researchers, for the first time ever, demonstrated a way to directly measure the t

gizmodo.com Ed Cara 2025-08-17 20:30:39

Scientists at Duke University led the study, published Wednesday in Nature. They found that nerve cells can respond in real time to bacterial signals from the gut—including signals that tell us to curb our appetite. The findings suggest the relationship we have with our microbial neighbors is even more

As a former girl scout I believe in leaving a place better than I found it. As a food writer and former culinary school student, this entails leaving behind a certain feature in any kitchen where I've lived. (As a former NYC resident, there were numerous kitchens.)
