I tried out the Feno toothbrush: a full-mouth, U-shaped toothbrush. It brushes your entire mouth in 20 seconds as opposed to the typical 2-minute brush time recommended for standard toothbrushes. The Feno toothbrush seemingly did a pretty thorough job of brushing my teeth and was quick and comfortable.

That includes at least 168 employees at the Environmental Protection Agency (EPA) who worked in its Office of Environmental Justice and External Civil Rights. The Trump administration is following a play out of Project 2025, which calls for “eliminating” the office.

I got to try out EssilorLuxottica’s Nuance Audio glasses last month at CES 2025. They look like normal glasses, but can amplify the voice of whoever you’re speaking to while also dampening noisy environments. Plus, since it can handle prescription lenses, it’s sort of like killing two birds with one stone. Now that they’ve got FDA clearance, the glasses are set to launch in the US in Q1 this year and the first half of 2025 in Europe.

According to Android Police, T-Mobile has added Google’s latest phones to its beta test of direct-to-cell satellite service powered by SpaceX’s Starlink. iPhones and a select few Samsung phones were already in the beta.

After studying Apple Watch noise data from the past four Super Bowl Sundays, we have quantifiable data showing that people get 1.5 to 3 decibels louder in the three hours before and after the game compared to the following Sunday. And yes, folks in game states are indeed louder than those in non-game states. Are we surprised at these findings? No, but it’s kind of fun to have data to point to.

After announcing a partnership with OpenAI last year, the US National Laboratory will now install the company’s latest reasoning models on its Nvidia-powered Venado supercomputer “to conduct national security research.”

Here’s the unelected government official speaking about his part-time hobby, Tesla:

The Senate confirmed his nomination today. Zeldin has been tasked by Donald Trump to “ensure fair and swift deregulatory decisions that will be enacted in a way to unleash the power of American businesses.” That seems to include removing roadblocks to building energy-hungry AI data centers in the US.

Ars Technica explains why even as off-the-cuff maybe-trolling, Musk’s recent comments about the ISS crew put a strain on NASA. Here’s the crux:

According to Bloomberg and user reports, T-Mobile’s list of eligible devices for beta testing Starlink direct-to-cell connections now includes iPhones. While only a few Samsung Galaxy devices were supported at first, now iPhone owners with the most recent update can reportedly connect, as well as some people with Android 15 devices.

It’s 89 seconds to midnight on the Doomsday Clock. Rest assured, the clock merely “visualizes humanity’s metaphorical proximity to global catastrophe,” according to the Bulletin of the Atomic Scientists that sets the time each year and updated it today.

The Minor Planet Center (MPC), which tracks and reports minor planet discoveries, recently removed a new listing of a near-earth object after the amateur astronomer who found it realized it was just the Tesla Roadster that was stuck to a rocket that SpaceX launched in 2018, according to Astronomy Magazine.

Android Authority reports that Samsung may be the first to noninvasive blood glucose monitoring in the Galaxy Watch, citing comments from Samsung senior vice president Hon Park saying the tech will be a “game-changer.”

Doritos are changing shape for the first time. A limited number of square chips will be hidden in UK bags to promote the upcoming Minecraft movie, with a cash prize if you find one. New flavors named after the game’s Creeper and Ghast enemies are going on sale too. PepsiCo’s chief chip technician — a job title we should all aspire to — is clearly proud of his work.

National Institutes of Health is reportedly reeling from canceled meetings and a communications and hiring freeze under the new Trump administration.

There are repair guides and replacement parts available for more than 20 Logitech devices, including keyboards, headsets, and MX / G series mice, on the iFixit-hosted Logitech Repair Hub — and now you can get them in 62 countries.

It’s “going to look a little different” as it migrates to a more general science site, according to NASA. President Donald Trump has called climate change a “hoax,” and researchers have been archiving environmental data in case it starts to disappear from federal websites.

NASA astronaut Don Pettit, who has taken some of the best photos of the stars and Earth ever captured aboard the International Space Station, recently shared a video on X highlighting how easy it is to juggle and swap big camera lenses in zero gravity. Keeping dust out of lenses is still an issue, but accidentally dropping one is not.
