Evidence for Ozempic’s broad health benefits is mounting David J. Phillip / Associated Press / Alamy Stock Photo The type 2 diabetes drug Ozempic has been linked to slower rates of ageing, and now we have good-quality evidence that this really does occur. GLP-1 drugs like Ozempic and Wegovy, both of which contain the medication…

“I was weightless. The pod had taken flight…” MarWin55/Getty Images/iStockphoto The drive was quiet. I put on the electronic music I liked but, feeling anxious, soon turned it off. I drove through to morning, along endless chain-link fences, escaping the Arctic Circle to find the sun. Its rise over the highway tundra was freer than…

“The faster the planet, the fiercer the storms…” elementix / Alamy Stock Photo In the past month, Earth experienced some of its shortest days on record. The planet spun quickly enough to shave 1.4 milliseconds off of its usual 24-hour day. These natural accelerations in Earth’s spin are, of course, hard to notice. But if…
Scientists are trained to thoroughly investigate their new ideas. Sometimes, however, their preliminary research can go down strange rabbit holes, leading to interpretations of evidence that are, well, misguided. In reporting on emerging science for 180 years, Scientific American has published straight accounts that were considered legitimate at the time but today seem quaint, quizzical,…
The Sirius binary star system photographed with a neuromorphic camera Satyapreet Singh, Chetan Singh Thakur, Nirupam Roy, Indian Institute of Science Cameras that mimic human eyesight could have key advantages for astronomers, allowing them to capture extremely bright and dim objects in the same image and track fast-moving objects without motion blur. Traditional digital cameras…
One of the most notable aspects about our planet—if observed from the outside—is that it spins. Earth’s spin defines our days, setting the fundamental rhythm of life on our world. The moon spins, too. So do the planets and all their moons. The sun spins as well, as do all stars. Even galaxies spin; the…
Light particles seem to exhibit quantum weirdness even when they aren’t entangled WLADIMIR BULGAR/SCIENCE PHOTO LIBRARY Particles that don’t seem to be entangled have earned a high score on a famous test of entanglement. The experiment could offer a fresh look at what makes the quantum world so strange. Nearly 60 years ago, physicist John…
More than half of U.S. newborns diagnosed with HIV in their first year of life had not been given a treatment known to prevent postnatal transmission from mother to child. That suggests that some maternal infections have been missed, researchers report in the July Pediatrics. “We need to do a better job of identifying HIV…
