This weird thing is a 1.2kW electric motor powered, carbon fiber foldable bike called the YikeBike. It's real, unfolds in 15 seconds, and aims to solve the eternal problem of urban mobility, and probably become Woz's favorite new toy.
Folded, the YikeBike only takes 6 x 23.6 x 23.6 inches (150 x 600 x 600 millimeters) and weighs 22 pounds (10 kilograms), so it can be easily carried around. And while its pneumatic wheels may follow an old high wheeler configuration, according to the manufacturer, this thing is designed to be easy to maneuver, and it's equipped with electronic brakes with built-in anti-skid system.Would this thing succeed where the Segway failed? Sadly, at $4900, I have a very bad feeling about it.[ via YikeBike ]

Garmin's cyclist-minded GPS devices have sure come a long way from their earlier, bulkier days, and it looks like the company has now produced one of its sleekest units to date in the form of its new Edge 500 GPS. Like most such devices, this one is primarily intended to track your cycling progress rather than lead you to your destination, and it promises to give you precise data on things like speed, distance, time, calories burned, and even climb and descent information, which is further bolstered by a built-in barometric altimeter to pinpoint changes in elevation. The unit can also sync up with various third-party devices that make use of ANT+ technology, and it can naturally be paired with a Garmin heart rate monitor to keep a close watch on your vitals. Look for the standalone unit to set you back about $250, while the bundle with a heart rate monitor and speed/cadence sensor bumps things up to $350.

MIT engineers are showing off the latest generation of so-called robofish 15 years after they built the first one. The latest incarnation is sleeker, more streamlined and capable of mimicking the movements of a real fish.And it's capable of exploring underwater terrain submersibles can't, said Pablo Valdivia Alvarado, a mechanical engineer at the school.

Some of our sponsors were thinking of using them for inspection and surveillance," Alvarado said. "Since these prototypes are very cheap, the idea was to build hundreds -- 200, 500 -- and then just release them in a bay or at a port, and they would be roaming around taking measurements.

MIT researchers built their first robotic fish, "Robotuna," in 1994. But Robotuna has gone the way of the dinosaur. Alvarado said the new generation -- modeled after bass and trout -- cost only a few hundred dollars and have only 10 parts instead of the thousands used in Robotuna.

Scientists from the RIKEN center in Japan have found a new way to make OLEDs, using electrospray-deposited polymer films, which they say have better characteristics than OLEDs made from spin-coated films. The researchers have used a novel dual-solvent concept to make the electrospray-deposited films smoother than before, thereby enabling the superior devices to be built.
