NASA’s Chandra Captures Young Star Surrounded by a Glowing Bubble

By Jackson Chung February 23, 2026

Astronomers pointed NASA’s Chandra X-ray Observatory at HD 61005, a star in the Puppis constellation that is approximately 120 light-years away. This star has roughly the same weight and temperature as our own Sun, but it is approximately 100 million years younger, a billion years or so younger than the Sun’s current age of 5 billion years. As one would anticipate from a young star, the surface of HD 61005 emits a far larger flow of charged particles; its wind is around three times faster and 25 times denser than our own solar wind.

Innovative Candle-Powered Energy Generator is More Useful Than You Think

By Jackson Chung February 23, 2026

Inventor Maciej Nowak was able to generate energy from the heat of a single tea candle. He configured the system such that the candle’s heat is transformed into enough juice to power two miniature LED bulbs. Plus, these lights emit significantly more light than a candle.

Modder Turns Samsung Galaxy S20 FE with Cracked Screen Into a Functional Mini PC

By Bill Smith February 23, 2026

A smartphone screen that’s seen better days doesnt mean the phone itself is about to kick the bucket, as proven by ETA Prime who took that battered Samsung Galaxy S20 FE and turned it into a mini PC for less than $100, and still had some cash left in his pocket.

UCSB Researchers Create a Liquid That Bottles Sunlight for Heat on Demand

By Jackson Chung February 23, 2026

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.

What You’ll Find Inside a Massive Water-Cooled Intel 3000W Power Supply

By Jackson Chung February 23, 2026

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.

Nintendo’s Virtual Boy Rides Again on Switch, Here’s How it Stacks Up Against the Original

By Bill Smith February 22, 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’s Galaxy Tab A11+ Proves You Don’t Need to Spend More for a Great Tablet

By Jackson Chung February 22, 2026

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.

How Bell Labs Stored Binary Information on Memory Devices Back in 1959

By Jackson Chung February 22, 2026

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.

Custom Arm-Mounted Plasma Cannon is a Real-Life Mega Man Mega Buster

By Bill Smith February 22, 2026

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.
