This is today's edition of The Download, our weekday newsletter that provides a daily dose of what's going on in the world of technology.
Solar geoengineering, the controversial idea that we could deliberately intervene in the climate system to counteract global warming, is moving beyond computer simulations and into the practical engineering challenges required to make it real.
Researchers are now working on aircraft, materials, and other systems for solar geoengineering. But as they delve into these details, they’re finding that even early deployment would require significant new infrastructure, time, and investment.
Find out what happens when solar geoengineering encounters the realities of trying to cool the planet.
Scientists have a word for how we sense ourselves from the inside: interoception. Today, thanks to a 2021 Nobel Prize and new tools that can map internal signaling across the body, research into interoception is taking off.
As researchers decode how signals move between body and brain, a clearer picture is starting to take shape—with implications for how we treat conditions from obesity to anxiety.

Watching DeepMind’s AI master the ancient board game Go, Demis Hassabis realized that his company was ready to take on one of the most important and complicated puzzles in biology: predicting the structure of proteins.
The result was AlphaFold2, an AI that could predict the shape of proteins down to the nearest atom. “It’s the most complex thing we’ve ever done,” Hassabis told MIT Technology Review.
Taking on scientific problems is the culmination of what Hassabis set out to achieve, and it’s what he wants to be known for. “This is the reason I started DeepMind,” he says. “In fact, it’s why I’ve worked my whole career in AI.”
Discover how he plans to transform science with AI.
