If you’ve ever lost footage or had your camera freeze up in the middle of recording, you know how critical a good memory card really is.

The 5 Best Essential Oil Diffusers (and One to Avoid)

I first learned about Pura from a friend whose house always smelled like a high-end boutique under every circumstance. Cooking project, water leak … no matter what was going on in her house at the time, I only ever smelled berries. I have two cats and a multi-sports-playing tween—I knew I needed this. Now, about 17 months into my Pura journey, I have some thoughts. While most of my time has been with the now discontinued Pura 3, I have also since used the Pura 4 and new large-room Pura Plus, al

Is mathematics mostly chaos or mostly order?

Last winter, at a meeting in the Finnish wilderness high above the Arctic Circle, a group of mathematicians gathered to contemplate the fate of a mathematical universe.

The consequences, Aguilera believed, were grand. “We just do

Tesla’s robotaxi reality check

The Download: Namibia’s hydrogen hopes, and fixing AI evaluation

Factories have used fossil fuels to process iron ore for three centuries, and the climate has paid a heavy price: According to the International Energy Agency, the steel industry today accounts for 8% of carbon dioxide emissions. But it turns out there is a less carbon-­intensive alternative: using hydrogen. Unlike coal or natural gas, which release carbon dioxide as a by-product, this process releases water. And if the hydrogen itself is “green,” the climate impact of the entire process will
