Sound has always been something you hear. At Virginia Tech, it is now something you can use to pick things up. Researchers there have built an electronic chip that generates acoustic waves precise enough to trap, steer, and move microscopic particles and fluids without making contact with them. Their findings were published in Nature Communications in December 2025.

Harvard Engineers Build Chip That Twists Light To Reveal Its Hidden “Handedness”

A twisted pair of photonic crystals integrated with MEMS can dynamically control the handedness of light on a chip.

A twisted pair of photonic crystals integrated with MEMS can dynamically control the handedness of light on a chip. Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a chip scale device that can actively control the “handedness” of light as it moves through it, a property known as optical chirality. The system works by slightly twisting two specially engineered photonic crystals.

Iran oil shock more likely to affect BTC miners through price than energy costs https://www.theblock.co/post/393531/iran-war-oil-shock-more-likely-to-affect-bitcoin-miners-through-btc-price-than-energy-costs-analysts-say Bitcoin miners may feel the effects of oil shocks linked to the war in Iran primarily through bitcoin's price volatility rather than their energy bills, according to new analysis from Luxor Technology's Hashrate Index. The research examined how a geopolitical shock affecting global energy markets could influence mining economics after coordinated strikes by the United States and Israel on Iranian targets disrupted tanker traffic through the Strait of Hormuz.

After self-hosting everything for a year, I learned that tech skills matter LESS than I thought

Good self-hosting is 80% behavior, and 20% technology.

We’re often told that self-hosting is a massive technical mountain that only "experts" or "pro coders" can climb. A year ago, I decided to find out for myself. I moved my entire digital life from the big cloud platforms to my own private server, thinking my background in software engineering would be my superpower.

While creating organs sounds like sci-fi fodder, scientists have actually experimented with the idea for more than a century. For example, in 1907, American biologist Henry Van Peters Wilson demonstrated the foundational principles of lab-grown organs, or “organoids,” by showing how disassociated cells from a sea sponge could self-organize and regenerate in vitro. For decades, this exploration continued on in various animals until eventually, in 2009, scientists created the first 3D organoid using the intestinal stem cells of a mouse.

Only a year later, he thinks he was wrong. “I now expect to lose this bet,” he declared on his blog.

More than a century before quantum mechanics was born, Irish mathematician William Rowan Hamilton stumbled onto an idea that would quietly foreshadow one of the deepest truths in physics. While studying the paths of light rays and moving objects, Hamilton noticed a striking mathematical similarity between them and used it to develop a powerful new framework for mechanics. At the time, it seemed like a clever analogy—but decades later, as scientists uncovered the strange wave-particle nature of light and matter, Hamilton’s insight took on new meaning.
