Researchers at UC Santa Barbara (UCSB) have developed a clear, reusable liquid that captures solar energy directly and holds it as chemical energy for months or longer, then releases the stored energy as heat when needed. All of this is feasible without the use of batteries or the conversion of energy into electricity, according to a recent study published in the journal Science. This is known as a molecular solar-thermal system, and it is enabled by the clever chemical pyrimidone.
A 3000W power supply often conjures up images of huge metal boxes with noisy fans pumping air over massive heat sinks, but this Intel reference unit blasts that idea out of the water, or rather keeps it cool, due to a water cooling system that keeps everything nice and clean.

The surprise arrival of the Samsung Galaxy S26 Ultra in some stores has got people really excited, with one very good unboxing video from a customer that allegedly shows the device in hand a good few days before the official Unpacked event on February 25, 2026.
Nintendo has resurrected a 1995 oddity and incorporated it into the Switch family, literally, as the original Virtual Boy sat on a table like a curiosity, a set of goggles perched on spindly legs offering 3D gaming without the need for glasses. Three decades later, almost to the day, a near-identical recreation of that table-top oddity is accompanying your Switch or Switch 2 console, launching the same old library via Nintendo Switch Online’s expansion pack.
Samsung released the Galaxy Tab A11+ late last year, and it quietly exceeded people’s expectations with what it does at a reasonable price for an Android tablet. Priced at $210 (was $250) for the 6GB RAM and 128GB storage edition, this 11-inch slate includes a slew of enhancements that feel like a game changer in a market where corners are typically cut.
This 1959 Bell Labs film provides a glimpse into a world where computers were little more than a collection of clever mechanical and magnetic tricks for storing anything in memory. It’s the story of engineers seeking to develop a solution to store binary data that was fast, reliable, and non-volatile, and could be accessed at any time without having to wait for a drum to spin or a tape to scan. One segment stands out for its innovative solution: the Twistor memory.
Arnold (Arnov) Sharma grew up playing Mega Man X on an ancient Windows 98 computer. Years later, he turned those hazy memories of his childhood into something he could wear on his forearm. It’s not just a replica but a functional Mega Buster, also known as the Rock Buster. Every detail on this replica stays true to the original, thanks to accurate measurements made in Fusion 360, which started with a reference image scaled to 330 mm in length.
NASA’s Perseverance rover has just reached a small but significant milestone on Mars. After five years of carefully traveling about the bottom of Jezero Crater, the rover now knows exactly where it is without having to rely on a crew on Earth. A new system called Mars Global Localization has made the task possible in less than two minutes, with accuracy to within ten inches.
Today, a single 1.44MB floppy disk is sufficient to run an entire operating system and a functional web server. Despite the fact that hardware costs are soaring, this demonstrates that you don’t need the latest and greatest to support a server; just a little old-fashioned efficiency.
A gravity-wielding winder appears, which resembles a sci-fi gadget rather than something you’d want on your desk. Metilis refers to it as the Gravity Furnace, which will come as no surprise. This single-watch winder spins automatic watches with the precision of a Swiss watchmaker, but instead of a boring wooden box, it resembles a chunky robot from an old-school anime.
