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.
The Giant Magellan Telescope is a marvel of engineering, and Dr. Patrick McCarthy explains the years-long process to make an optic mirror that costs over $20 million.
Anthony Atala, director of Wake Forest University’s Institute for Regenerative Medicine, is developing techniques to 3D print human organs for transplant using an individual’s own cells as the “ink.” That way, the transplanted organ won’t trigger the patient’s immune system to reject it as a foreign body. From National Geographic: (For example,) to create an […]
A Scottish team of animal biotechnologists announced this week they successfully introduced human stem cells into sheep embryos. Perhaps one day we will all have our very own baaing organ donors. The team are currently allowed to let the chimeric embryos develop for 28 days, 21 of which are in the sheep. While that might […]
Surfing on public Wi-Fi is convenient, but it’s far from safe. Whether you’re at a cafe or hotel, connecting to an unsecured network exposes you—and your personal information—to a host of hazards, including hackers, government spies, and trackers. Private Internet Access helps you navigate past these risks and tap into a safer, restriction-free internet, and […]
The web is vast, and while there’s room for everyone, competition is stiff when it comes to landing on that first page of a Google search. That’s why developers aren’t afraid to spend exorbitant amounts of time and money on search engine optimization (SEO) to ensure their sites rank higher than others. However, not all […]
Many of us enjoy the aesthetic of vintage electronics, but trying to use most hardware from the 1950’s isn’t necessarily practical. This is especially true where speakers are concerned. While most of us can appreciate the old-school feel of retro speakers, they have a hard time matching the convenience and power delivered by today’s Bluetooth speakers. […]
