Keep Computer Duster Very Far From Boiling Water
Despite the name “canned air,†computer duster isn’t oxygen at all. It’s actually 1,1-Difluoroethane kept under pressure in its liquid form and released as a freezing cold gas. It can cause moderate frostbite. It can get you high if you huff it (but don’t do that—it’s a truly awful idea.) And it makes boiling water explode. Wait, what?

How to Mute Specific Sites in Your Browser
Having to close a tab with audio blaring from an auto-play ad is one of the web’s greatest annoyances, but at the same time, most of us want to hear videos coming from YouTube or Netflix. How do you mute one without the other? Fortunately, there are a couple of easy solutions available.

Happy 50th Anniversary, Star Trek
On September 8, 1966, exactly 50 years ago today, the very first episode of Star Trek aired on television. More than just science fiction, it dared to imagine a future for humanity where it had moved past war, inequality, and poverty, replacing them with tolerance, exploration, and hope. And it’s not an exaggeration to say that Star Trek changed the world.

Netflix orders a series from ‘Mythbusters’ veterans
Still missing Mythbusters? It’s not about to come back any time soon, but you might get the next best thing. Netflix (which has a habit of resurrecting fan favorite shows) has greenlit White Rabbit Project, a series from Mythbusters Build Team veterans Kari Byron, Grant Imahara and Tory Belleci. The premise is right up their alley. They’ll investigate strange topics (such as exotic World War II weapons or seemingly impossible jailbreaks) and use science to determine the truth. You won’t have to wait long to see how well the concept works, either — Netflix premieres White Rabbit Project on December 9th, so you won’t have to put up with the year-long waits that come with other streaming releases.

Indian researchers recycle fish scales into energy nanogenerator
Indians consume a lot of fish: Data from 2014 estimated that each urban citizen consumed an average of 2.8 kg per year, or about 3.7 million kg for the whole country. That leaves a lot of leftover bones, scales and tails. As they reported this week in Applied Physics Letters, a team of researchers at Jadavpur University looked for ways to re-use this "biowaste" and pioneered a method to generate electricity from it.
First, some biophysics. Fish scales have collagen fibers containing piezoelectric properties: Stress them and you generate a charge. Considering this, the researchers collected a large volume of them and used a demineralization process to make them transparent and flexible. Then they toyed with the hierarchical alignment of these treated scales, boosting their energy yield and effectively creating a bio-piezoelectric nanogenerator.
It can scavenge several types of ambient mechanical energies like body movements, machine and sound vibrations and wind flow. Even touching the nanogenerator produced enough electricity to light 50 LEDs. The result is a big step for self-powered flexible electronics, which could one day be developed into things like pacemakers energized by heartbeats that safely biodegrade in time. While it could also find applications in transparent and portable electronics, the biocompatibility likely makes this tech more valuable to medical uses like e-healthcare monitoring, in vitro diagnostics and edible devices.
