Please keep Anish Kapoor away from the whitest white paint

Researchers at Purdue University say they have created the whitest paint on record. In fact, they’ve now crafted an ultra-white paint twice: in October, they announced a white paint that was capable of reflecting 95.5 percent of sunlight. But they decided to outdo themselves with a new formulation, announced today, that reflects up to 98.1...

There are also doughnuts. But there’s also a pretty good chance that a vaccine will be accompanied by a few unwelcome side effects. Most of...

One side effect of the COVID-19 vaccine could be a heavier period

Katharine Lee got her COVID-19 vaccination early on in the United States’ rollout. So did a friend of hers — they got their shots on the same day. They compared notes, curious to see what the side effects would be. Lee, a research fellow in the Division of Public Health Sciences at Washington University in...

Watch: Elon Musk’s Neuralink says this monkey is playing Pong with its mind

Neuralink, Elon Musk’s company focused on developing brain-machine interfaces, has posted a video to YouTube that appears to show a monkey navigating an on-screen cursor using only its mind. Pager, a 9-year-old macaque monkey, had a Neuralink implanted about six weeks before the video was shot, the video’s unnamed narrator says. He was first taught...
