An AI “mind-reading” tool can reconstruct what you’re looking at from a brain scan
A new AI tool can guess what you’re looking at just by analyzing your brain scans—and re-create that image with remarkable precision. It can go the other way, too, and predict a person’s brain activity based on what they’re looking at. In the image above, for example, the left-hand image of each pair is what…
How smaller, distributed batteries could help the grid
If you want to install a big battery in New York City, you have to cut through a notoriously tough tangle of regulations. That’s made it difficult to get large energy storage projects on the grid. Faced with those obstacles, some startups are getting creative, finding ways to use relatively small batteries in unexpected places,…

Coming soon: Our 2026 list of Climate Tech Companies to Watch
Earlier this month, the UN announced the planet will tip past 1.5 ˚C of warming, “likely within the next few years,” squashing any lingering hope that nations would cut emissions fast enough to achieve the loftiest goal of the Paris climate agreement.

The program, called Polygraph+ or Polygraph Next, will focus on scoring algorithms that use artificial intelligence and machine learning and on a technique called “standoff sensing,” which…
Young organs may not be a fountain of youth for recipients

News outlets were reporting that a hot mic had caught Russia’s and China’s leaders discussing the possibility of living forever. “With the developments of biotechnology, human organs can be continuously…
