Liquid oxygen is used in rockets and treated with care in laboratories, but it’s not something that people think about in everyday life. Except for one maker who was interested as to why this was the case, so he decided to make some at home and examine what makes people so cautious about it.

Donut Lab, a Finnish company, recently released some impressive test data demonstrating how their solid-state battery handles extreme temperatures that conventional lithium-ion cells would struggle to deal with. The test results come from a series of measurements conducted by the VTT Technical Research Centre of Finland, a respected, government-backed research organization. They needed to figure out precisely how high the heat could reach before this Donut Lab cell, rated at 3.6 volts and 26 amp-hours, blew up in smoke (or some other way), so they decided to put it through its paces.

In terms of fit and feel, Apple’s earbuds have always been a source of contention. Some swear by the sealed tips on the Pro models for keeping everything out, while others prefer the normal versions to prevent the uncomfortable plugged-up feeling. Then Apple debuted the AirPods 4 with active noise cancellation, and for $119 (was $179), they manage to make a huge difference in terms of quietness without requiring you to insert a seal into your ear canal.

Pokémon turns 30 this year, and the Pokémon Company wants to give its followers a little something to celebrate. They created the Game Boy Jukebox, which is a modest tribute to the original Game Boy. It’s a device that pulls music directly from Pokémon Red and Blue. We’re talking 45 tiny mini cartridges buried in the box, each with a single track or sound effect from the original 1996 games.

This step transforms what was previously a decent mid-range iPad Air into a full-fledged laptop replacement for many more users. The 11-inch model starts at $599, the 13-inch at $799, and the same goes for Wi-Fi models. When you add cellular service, the price goes up by $150. If you are a student, you can save some money: the 11-inch model is just $549. Pre-orders begin on March 4th, 2026, and the devices arrive in buyers’ hands on March 11th.

Matthew Perks has truly outdone himself with his new invention, a highly portable powerhouse surrounded by one of the world’s brightest LEDs. The device, known as the LED supernova, takes 1.5 kilowatts of power and converts it into a dangerously eye-searing 120,000 lumens, all in a compact box weighing only 25 kg and remaining (amazingly) portable.

A new video from Pratt & Whitney has reignited controversy over the Boeing F-47, which is slated to be the 6th Generation fighter that would eventually replace the F-22 Raptor. Halfway through a short animation focusing on engine progress, an animated fighter jet arrives in flight, its two engines burning brightly as it slashes through a picture-perfect blue skies. Observers quickly identified the image as a possible portrayal of the F-47 itself, powered by Pratt & Whitney’s XA-103 engine, which is now under development.

When Billet Labs began on this project, they faced an unexpected challenge: transforming a Victorian-era antique into a functional living room display. When fully loaded with water, the finished creation weighs a massive 99 kilograms (218 pounds), combining the elegance of ancient heating technology with some seriously modern components, and its background as a Victorian radiator just adds to its charm.
