It's a brilliant idea: Put solar panels on a drone so it doesn't need a battery. Without a battery, you could fly a drone as long as the sun keeps shining. It's awesome (assuming your motives are pure). That's exactly what students at the National University of Singapore did. But if you watch the video,…

Andrew Rubin sits with a Surface tablet, watching a white skeletal hand open and close on its screen. Rubin’s right hand was amputated a year ago, but he follows these motions with a special device fitted to his upper arm. Electrodes on his arm connect to a box that records the patterns of nerve signals…

Update: After delays, this launch successfully took place on Monday, Dec. 3. On Sunday, SpaceX plans to hoist into space the largest cosmic carpool to depart from US soil. The California-based aerospace company is flexing its ridesharing muscles in a carefully choreographed orbital ballet as its flagship rocket—the Falcon 9—prepares to launch 64 small satellites…

Francesco Ricci stands at a table covered in a tangle of wires and tiny mirrors. “Here is where everything happens,” he says, pointing to a metal cylinder roughly the size of a cookie tin. A graduate student at the Institute of Photonic Sciences in Barcelona, Ricci is showing me a device he’s built to survey…

I'm oddly attracted to The Titan Games. I think we can all agree that this is the newest incarnation of the popular '90s show American Gladiators. It's not the theatrics that I enjoy, it's the crazy competitions. As you can imagine, there's a bunch of cool physics to talk about for some of these events.…

This story originally appeared in the Guardian and is part of the Climate Desk collaboration. New York is suing the oil giant ExxonMobil in a lawsuit that claims the company engaged in a “longstanding fraudulent scheme” to downplay the risks posed to its business by climate change regulations. The legal action, launched by New York…
