Watch: video of a stable plasma torusOn January 1, 2018 by Kenna
Caltech posted video of a stable plasma torus, created by engineers using water and a dielectric plate: “lightning in a bottle, but without the bottle.”
In addition, engineers working with the plasma noticed that their cell phones encountered high levels of radio frequency noise—static—while they were in the same room as the experiment. It turns out that the plasma ring emits distinct radio frequencies. “That’s never been seen before. We think it’s because of the piezo properties of the materials that we used in our experiments,” Pereira says, referring to the materials’ ability to be electrically polarized through mechanical stress—in this case, the flowing of water.
They’ve got no idea what it might be useful for, but have already filed a patent on the method for genereating the torus. Commercial proposal: a pretty random number generator to replace the lava lamps in Cloudflare’s HQ.
If you’ve ever observed “wine legs,” the rivulets that form when you swirl wine in a glass, you’ve seen the Marangoni effect. Watch how scientists are using this effect to create tiny motors that emit no pollutants.
MIT researchers have figured out how to infuse common plants like watercress and arugula with luciferase, the chemical that makes fireflies glow. The process make the plants emit a dim glow for up to four hours. Via MIT: Previous efforts to create light-emitting plants have relied on genetically engineering plants to express the gene for […]
Stephen Canfield and his colleagues at WeTransfer curated a stunning online experience inspired by the Voyager Golden Record, the iconic message for extraterrestrials launched into space on a phonograph record 40 years ago. My friends Tim Daly and Lawrence Azerrad and I co-produced the first ever vinyl release of the Voyager Record this year and […]

SunFounder’s Nano DIY 4-DOF Robot Kit offers an intuitive and beginner-friendly way to break into the field by walking you through building your own programmable robot, and you can get it in the Boing Boing […]
You may not have heard of blockchain technology, but you’re likely familiar with Bitcoin, the now wildly successful cryptocurrency. For the uninitiated, the blockchain is effectively an infallible, decentralized digital ledger that records economic transactions online, and it has paved the way for cryptocurrencies like Bitcoin and Ethereum to turn the world of finance on its […]
With new, innovative apps and programs dropping everyday, it pays to have a powerful computer. But forking out the cash for a pre-made rig can get expensive — especially when it’s perfectly feasible to build your own at a much lower price point. Of course, not all of us have the IT acumen of a […]
