Gravity-defying levitating superconductor on a magnetic Möbius strip
Nothing to add. Absolutely amazing. Except that a real life wipeout is closer than you think. From BoingBoing:
Andy from the Royal Institution made a large, suspended Möbius strip out of rare-earth magnets, then cooled down an object until it became a superconductor, and set it levitating and running around the track. The result is amazing, plus Andy’s explanation is cogent and fascinating. Plus, gravity-defying levitation!
I watched the TED Talk about this a while back. Pretty fascinating material!
Privacy visor glasses jam facial recognition systems to protect your privacy
This is the world’s first pair of glasses which prevent facial recognition by cameras. They are currently under development by Japan’s National Institute of Informatics. Photos taken without people’s knowledge can violate privacy. For example, photos may be posted online, along with metadata including the time and location. But by wearing this device, you can stop your privacy from being infringed in such ways.
Should go nicely with my aluminum foil hat. :-P
The RoboRoach is a $99 kit consisting of electrodes, sensors, and a few batteries that allows anyone to drive their very own cockroach.
Attaching the electronic “backpack” to an unwitting arthropod is not for the squeamish. You must sand down the top of the critter’s head in order to attach a plug, “Exactly like the Matrix,” says Backyard Brains cofounder Greg Gage. Once installed, the system relays electrical impulses over a Bluetooth connection from your phone to the cockroach’s brain, via its antennae. The roach perceives each stimulus to its antennae as an obstacle, and changes direction. The same technique, applied to the cilia of the inner ear, is used in cochlear implants and during deep brain stimulation for treating a variety of disorders.
Greg Gage is an electrical engineer-turned-neuroscience student at the University of Michigan who, with his cofounder Tim Marzullo, started developing the RoboRoach three years ago. “The reason why we started is because I was annoyed that it was so late that I found out about a career in neuroscience. We have one in five people with a neurological disorder and we have no cures—we’re kind of in the dark ages. We want to get kids to understand that this is a career, and you can do so many amazing things.”

Ryan Gosling in his most dynamic role yet… He played hot guy poor kid lover, snobby teenage serial killer, hot lover/killer/cross dressing old guy… Now nature calls in the summer romance Duck Duck Gosling.
