Scientists create gold nuggets that are 98 percent air

Researchers at ETH Zurich have accomplished a bit of modern-day alchemy, transforming 20 carat gold into a lightweight foam. Well, technically it’s an aerogel: an exceedingly light and porous matrix of material. It’s so porous, in fact, that the foam doesn’t conduct electricity because, at atmospheric pressure, the gold atoms within the structure don’t actually touch. “The so-called aerogel is a thousand times lighter than conventional gold alloys. It is lighter than water and almost as light as air, ” Raffaele Mezzenga, Professor of Food and Soft Materials at ETHZ, said in a statement. Via: GizMag Source: ETH Zurich

This crowdfunded router updates its own security

It’s really, really, really hard to make a router sound exciting , but the folks behind the Turris Omnia are betting the device’s focus on keeping your sensitive data secure might grab you. The manufacturer’s IndieGogo campaign still has 45 days to go, but it’s already proved incredibly popular: over a thousand backers have pledged some $274, 598 as of this writing. That’s 275 percent higher than the threshold for funding the project. The router itself runs Turris’ open source operating system (based on the OpenWRT project ) which auto updates as soon as any type of vulnerability is discovered by its cadre of developers.

E-paper sneakers change your style on the fly

If you’re the sort to buy multiple pairs of sneakers just to make sure your footwear is always fashionable, you might soon have a way to save a lot of money. David Coelho is crowdfunding ShiftWear , or sneakers that have color e-paper displays in their sides. You only need a mobile app to change your look at a moment’s notice (there are promises of a shoe design store), and you can even use animations if you’re feeling ostentatious. The shoes are machine-washable, and the e-paper consumes virtually no power if you’re using static imagery — there’s even talk of walk-to-charge tech that would save you from ever having to plug in or swap batteries.

Amazon Video gets a bunch of new features on iOS

Amazon has released a ton of new features for its Video app. The update includes 3D touch support, Next Up (which is basically auto-play), picture-in-picture and X-Ray, which offers a wealth of IMDB information and trivia at the touch of a button. Even though some of these features are iPad exclusive (like picture-in-picture) they can help Amazon stand up against competition like Netflix when content alone won’t carry the day. The 3D touch option is only available on Apple’s latest smartphone offerings, the 6s and 6s Plus, and lets you access a number of features faster, but offers nothing in the way of exclusive functionality. Also, the app has been customized for the iPad Pro , meaning Amazon-exclusive content is bigger and better than it’s ever been before. What more could you ask for? [Image credit: AOL] Source: iMore

Jeff Bezos beats Elon Musk’s SpaceX in the reusable rocket race

Blue Origin, the private space firm owned by Amazon’s Jeff Bezos, has just dropped a huge, unexpected gauntlet in the race to develop a reusable rocket. In video released by the company (below), it managed to launch its New Shepard space vehicle consisting of a BE-3 rocket and crew capsule to a height of around 100.5 kilometers (62 miles). Minutes later, the capsule made a controlled landing beneath a parachute, but more importantly, the BE-3 rocket started its own decent when rockets fired at 5, 000 feet. From there, it made a a controlled vertical landing and touched down at a gentle 4.4 mph. Source: Blue Origin , Blue Origin

NASA’s FireSat system will be able to detect wildfires from space

NASA’s Jet Propulsion Laboratory and San Francisco-based company Quadra Pi R2E are developing a space-based wildfire detector that can keep an eye on the whole world. This system, called FireSat, will be made up of over 200 thermal infrared imaging sensors installed on satellites in low-Earth orbit. It will be powerful enough to detect wildfires 35 to 50 feet wide within 15 minutes from the time they begin. And since wildfires spread very quickly , it will have the capability to contact authorities, so they can send emergency responders to the scene as early as possible. Source: NASA

Digiday has spotted a thread on the Adblock Plus forums with complaints from a couple of people who couldn’t access Yahoo Mail on both Chrome and Firefox. One of them posted a screenshot of the message he got asking him to “disable Ad Blocker to continue using” the service, which you can see below the fold. If you take a close look at the URL, you’ll see that it says “reason=ADBLK_TRAP.” Via: Digiday Source: Adblock Plus

Doctors can now grow human vocal cords in a lab

Used to be that if you damaged your vocal cords and needed a new set, doctors would have to shoot you full of immunosuppressants to keep your body from rejecting the cadaver-sourced replacements. Not anymore. Researchers at University of Wisconsin Medical School have published a preliminary study in the journal Science Translational Medicine wherein they successfully cultured 170 sets of vocal cords in the lab. These organs do not require the course of immunosuppressants that conventional transplants require. “We never imagined that we would see the impressive level of function that we did, ” study senior author Nathan Welham told Buzzfeed .
