The European Union now prohibits desflurane’s use during most procedures. Desflurane is a common anesthetic used in hospital operating rooms worldwide. It’s also a climate super pollutant. Now, several decades after the drug was first introduced, a growing number of US hospitals have stopped using the anesthetic because of…
Ars’ total charity haul since 2007 now tops $585,000. Last month, we asked readers to donate to a couple of good causes in our 2025 Charity Drive sweepstakes. And boy, did you deliver. With the drive now complete and the donations all tallied, we can report that Ars Technica…
It’s like Tesla Autopilot, but made by a company with a culture of safety. There’s some debate as to when adaptive cruise control first showed up, but if you ask Mercedes-Benz, it will say in 1999 with that year’s S-Class. Instead of just keeping a set speed, radar-enabled adaptive…

Double-detonating “superkilonova,” Roman liquid gypsum burials, biomechanics of kangaroo posture, and more. It’s a regrettable reality that there is never enough time to cover all the interesting scientific stories we come across each month. In the past, we’ve featured year-end roundups of cool science stories we (almost) missed. This…
Streaming may get a little worse before it gets better. We’re far from streaming’s original promise: instant access to beloved and undiscovered titles without the burden of ads, bundled services, or price gouging that have long been associated with cable. Still, every year we get more dependent on streaming…
This time, a Colorado plant scheduled to shut down will be kept on standby. On Tuesday, US Secretary of Energy Chris Wright issued a now familiar order: because of a supposed energy emergency, a coal plant scheduled for closure would be forced to remain open. This time, the order…
