Electric cars produce far less brake dust pollution than combustion-engine cars

news.ycombinator.com William Harrison 2025-08-18 12:13:20

“It’s not just the tailpipe y’all,” joked one Electrek commenter, alluding to the black discolorations on alloy wheels visible proof of a less infamous city pollutant: brake dust. For decades, exhaust emissions have been the focus of city-air cleaning initiatives, but a new wave of research indicates that the real story goes far beyond the muffler.

Google DeepMind's Aeneas model can restore fragmented Latin text

engadget.com Unknown 2025-08-19 02:20:04

At its best, AI is a tool, not an end result. It allows people to do their jobs better, rather than sending them or their colleagues to the breadline. In an example of "the good kind," Google DeepMind has created an AI model that restores and contextualizes ancient inscriptions. Aeneas (no, it's not pronounced like that) is named after the hero in Roman mythology. Best of all, the tool is open-source and free to use. Ancient Romans left behind a plethora of inscriptions.
