A slowing Atlantic current could unleash stronger California storms
A weakening Atlantic current could supercharge California’s atmospheric rivers while leaving Greenland with fewer snow-producing storms. The changes could raise flood risks, strain infrastructure, and reshape water supplies far beyond the Atlantic.
Misfolded insulin may be quietly driving diabetes
Researchers found that insulin-producing cells depend on a team of helper proteins to keep insulin production on track. When one key partner was missing, damaged proteins built up and the cells made less insulin. Strengthening this system could offer a…
Hidden charcoal reveals the true age of ancient cave paintings
A new analysis has precisely dated paintings in France’s Font-de-Gaume cave for the first time. Scientists discovered charcoal inside black pigments once thought to contain only minerals, allowing them to use radiocarbon dating. The results show that a…
Why losing weight may not be enough to prevent type 2 diabetes
A healthy lifestyle can prevent type 2 diabetes for many people, but new research suggests that weight loss alone may not be enough for one particularly vulnerable group. Even after losing about 8% of their body weight and keeping it off for years, peo…
NASA’s Psyche spacecraft aces Mars flyby capturing stunning timelapse video
NASA’s Psyche spacecraft aced its Mars flyby, using the planet’s gravity to speed toward its 2029 encounter with a metal-rich asteroid. The spacecraft tested its cameras, magnetometer, and particle-detecting instruments, capturing unusual views of Mars…
Blazing like 10 billion suns: NASA’s Swift sees a wandering black hole devouring a star
NASA’s Swift Observatory observed a supermassive black hole ripping apart a star more than 30,000 light-years from the center of a distant galaxy. The extraordinary flare briefly outshone its entire host galaxy in ultraviolet light and revealed a black…
Scientists create an “electron lighthouse” with laser light
Scientists have created an “electron lighthouse” that uses laser light to launch and steer electrons through a semiconductor without an applied electrical field. The quantum effect could eventually improve optical sensors, communications, imaging, and …
Twisted laser light can tell mirror-image molecules apart
Scientists have created twisted laser beams that interact differently with right-handed and left-handed molecules, revealing their identity through the fragments they produce. The approach could provide a faster, simpler, and more sensitive way to anal…
A single sauna session sends immune cells surging
A single 30-minute sauna session may briefly put the immune system on higher alert. Finnish researchers found that sauna heat, paired with a short cold shower, increased every type of white blood cell circulating in the bloodstream, including key infec…
