Why endless scrolling gets harder to stop: Three drivers of problematic internet use revealed

From a geothermal hotspot to the one-time “Lighthouse of the Pacific,” the heat is on beneath the volcanic landscape of western El Salvador.

In the past, scientists thought that prehistoric peoples only traveled briefly through high-altitude mountain areas, rather than staying to take advantage of their resources. But new evidence suggests that, starting about 5,500 years ago, a prehistoric community repeatedly climbed up to Cave 338, 2,235 meters above sea level in the Pyrenees, to collect and process malachite for copper—returning many times over thousands of years. Additional finds, including jewelry, suggest that much more remain

A new quantum physics study reveals that simply changing a magnetic field over time can unlock entirely new forms of matter that don’t exist under normal conditions. By carefully “driving” materials with timed magnetic shifts, researchers created exotic quantum states that could be far more stable and resistant to errors—one of the biggest challenges in quantum computing. This breakthrough suggests that the future of quantum technology may depend not just on what materials are made of, but how t

On a March afternoon, artificial intelligence detected something resembling smoke on a camera feed from Arizona's Coconino National Forest. Human analysts verified it wasn't a cloud or dust, then alerted the state's forest service and largest electric utility.
