Slow Wi-Fi? Add a wired network to your home without an Ethernet cable - here's how

Best Electric Toothbrushes You Can Buy in 2025 — Tested by Experts

Regarding Prollyferation: Followup to "People Keep Inventing Prolly Trees"

Last month I published a blog post about the parallel invention of Prolly Trees, where I observed the repeated independent invention of a certain type of data structure within a relatively short period of time. In short, I described the concept of a Merkle Tree created by applying a content-defined chunker to a file, hashing the chunks, and then recursively reapplying the chunker to the concatenated list of hashes until only a single chunk remained. Each iteration of this process defined a sepa

Major Satellite Suddenly Disappears

A satellite designed to monitor human-made methane emissions has gone missing in space. Dubbed MethaneSAT, the $88 million spacecraft was launched into orbit aboard a SpaceX rocket in March 2024 and was expected to collect data on the potent greenhouse gas for at least five years. But for the past two weeks, the satellite's operators, the nonprofit Environmental Defense Fund, have been unable to establish contact. Now, in a final blow, mission control says that MethaneSAT has lost power, crus

This Prehistoric Trick Shows How Ice Age People Harvested Teeth for Jewelry

When piecing together the cultural practices of ancient humans, traditional archaeologists rely on clues from artifacts such as tools, bones, and pottery. Experimental archaeologists, however, go a step further—recreating past behaviors to experience how people once lived. That’s precisely what a team of researchers recently did to investigate how Stone Age communities in northeastern Europe extracted animal teeth to produce accessories.

The axion may help clean up the messy business of dark matter

In recent years, a curious hypothetical particle called the axion, invented to address challenging problems with the strong nuclear force, has emerged as a leading candidate to explain dark matter. Although the potential for axions to explain dark matter has been around for decades, cosmologists have only recently begun to seriously search for them. Not only might they be able to resolve some issues with older hypotheses about dark matter, but they also offer a dizzying array of promising avenue

The Methaphone Is a Phone (That’s Not a Phone) to Help You Stop Using Your Phone

Earlier this year, Eric Antonow was in a coffee shop with his family when he felt the familiar, twitchy urge to reach for his phone. He patted his pockets for relief—the cool, thin slab was still there. He joked to his family that, like an addict jonesing for a hit, he would one day need a medical-grade solution to detox from his phone. Opioid addicts had methadone. iPhone addicts would need … methaphones. “It was a joke, but I got two laughs from my two teenagers, which is gold,” Antonow says.

Methane Pollution Has Cheap, Effective Solutions That Aren’t Being Used

This story originally appeared on Vox and is part of the Climate Desk collaboration. Odorless and colorless, methane is a gas that is easy to miss—but it’s one of the most important contributors to global warming. It can trap up to 84 times as much heat as carbon dioxide in the atmosphere, though it breaks down much faster. Measured over 100 years, its warming effect is about 30 times that of an equivalent amount of carbon dioxide. That means that over the course of decades, it takes smaller a
