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.
Hawaiian monk seals are endangered and closely monitored by NOAA scientists who are alarmed that the seals keep getting eels stuck really deep in their nostrils.
For the first time, we can hear the “sounds” of wind on Mars as captured by the scientific instruments on NASA’s InSight robotic lander. From NASA: “Capturing this audio was an unplanned treat,” said Bruce Banerdt, InSight principal investigator at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California… Two very sensitive sensors on the spacecraft […]
Since the InSight robotic lander touched down on Mars last week, engineers have been putting its scientific instruments through their paces. This included extending the lander’s 6 foot (2 meter) robotic arm that will be used to deploy instruments and take images of the Martian surface. “Today we can see the first glimpses of our […]
Take a scroll through any app marketplace and you’ll see that the doors are wide open for any game these days – and any game developer. Like any creation, virtual or analog, it all starts with an idea. And if you’ve got one of those, the Complete Unity Game Developer Bundle can walk you the […]
At the rate the world is shrinking, you don’t need to be a globetrotter for a second language to be a useful skill. And if you’re looking to learn that second language (or a third, or fourth), uTalk Language Education is the learning program that makes progression not only easy but fun. If you can’t […]
Smokers on the go can breathe a little easier. With an innovative, easy-loading spiral design, the Twisty Glass Blunt offered a smoother, more consistent draw than conventional pipes. Now the Twisty Glass Mini delivers the benefits of its heavy-duty sister pipe in a more discreet package. For those that haven’t already made the Twisty Glass […]
