Google Glass-based system identifies you by the sound of your skull

Google Glass may be pretty much dead, but smartglasses in some form are likely to be a part of our future (whether near or distant). When that day comes you don't want just anyone picking up yours and using it without permission. Conventional passwords are one way to go, but scientists from Germany's Saarland University and University of Stuttgart have developed an alternative that doesn't involve having to memorize anything – you do, however, have to let the glasses buzz your skull.Read More

Mountain meets the sea in new diving fin design

Inspired by modern click-in/click-out ski binding systems, Italian entrepreneur Paolo Piumatti figured that scuba divers could benefit from something just as convenient. The resulting Finclip system lets divers get their fins on with no awkward bending over or sitting down.Read More

Experimental smartwatch has a movable second screen

Smartwatches may be less cumbersome than smartphones, but those little screens of theirs can only display a limited amount of content. We've already seen efforts to move the touchscreen control surface off of the watch, but researchers from Dartmouth College are taking another approach – they've created a prototype smartwatch with two touch-sensitive screens.Read More

A bike rack for cyclists who hate racks

Rear racks and panniers may indeed be useful, but they're also one of those things that many self-proclaimed "bike snobs" would never mount on their glorious two-wheeled work of art. So, what's a snob to do if they've got gear to haul? Well, they could always try the Tailfin. It's an aerodynamic carbon fiber rack/pannier combo, that wouldn't look out of place in the Tour de France.Read More

Brain-scanning helmet detects concussions

Whether they've been involved in a sports mishap, a car accident or something else, if someone has received a traumatic brain injury, they need medical attention as soon as possible. With that in mind, we've recently seen several portable devices that can ascertain if such an injury has occurred, quickly and on the spot. Still, none of those systems are as reliable as an EEG (electroencephalogram), which measures electrical activity in the brain. Soon, it may be possible to conduct on-location EEGs, using a special helmet known as the EmerEEG.Read More

Digital Cameras

Bug-eyed camera streams real-time 3D video

By now, just about everyone is familiar with video cameras that record in 3D, or that transmit traditional 2D footage. Vairdo's new EYSE actioncam, however, is actually capable of live-streaming high-definition 3D video. This means that one person can wear the camera while performing activities such as skiing, allowing someone else to view their immersive first-person footage as it's being shot.Read More

Cactus-inspired membrane boosts fuel cell performance

Here's something that you might not know about the humble cactus: it has tiny cracks in its skin, which open up at night when conditions tend to be more humid. This allows it to take up moisture. During the day, those cracks close up, keeping the moisture inside. Now, scientists have applied that same principle to a membrane which could make fuel cells a more viable option for powering vehicles.Read More

Silk coating makes for fresher fruit

How often do you end up throwing out fruit that spoiled before you could eat it? Well, it may soon be happening a lot less, thanks to a silk-based coating being developed at Tufts University in Massachusetts. Strawberries treated with the substance remained fresh and juicy for up to a week without refrigeration – unlike their untreated counterparts.Read More
