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.
Writing for the New York Times, Heather Murphy has a fascinating story about the unexpected results of a bone marrow transplant. When a patient receives a bone marrow transplant, the patient’s own cells are destroyed and replaced with cells from a donor. Thereafter, the patient is a “chimera,” with two sets of DNA. It’s believed […]
The Australian Acoustic Observatory project, described by its creators as a kind of “Google Street View of sound,” is a new acoustic sensor network of hundreds of microphones and digital audio recorders distributed across multiple remote ecosystems on the continent. The solar-powered system will record animal and natural sounds continuously for 5 years. According to […]

With all the revolutionary tech that’s out there, it’s pretty sad that finding a simple stud in your wall can feel like dowsing for water. This can be equally true whether you’re using a magnetic finder and it’s reliance on “feel,” or an electronic unit that can give fuzzy readings (especially when the batteries are […]
Do you have any Star Wars fans on your list? Given the reach and output of its new corporate masters these days, it might be easier to ask if there’s anyone out there who isn’t a Star Wars fan. So let’s narrow it down further: Do you know a Star Wars fan who likes to […]
