Researchers develop 'wireless optical brain router' to manipulate brain cells
Optogenetics might be a relatively unknown area of neuroscience, but it's one that, thanks to some new research, could soon find itself (and its rodental subjects) in the spotlight. For the uninitiated, it's the practice of manipulating animal cells using light (with a little help from gene therapy). Until now, optogenetic equipment has been large and unwieldy, making testing on subjects (read: rats) painstaking. Startup, Kendall Research, has changed all this, creating wireless prototypes that weigh just three grams (0.11 ounces). By eschewing bulky Lasers for LEDs and Laser diodes, the equipment is small enough that it can be attached to the rodents. At that point, their brain function can be manipulated with the touch of a button, and different parts can be stimulated without breeding mutant variants -- a controversial practice that doesn't even yield results in real time. The "router" is powered wirelessly by super capacitors below test area, and researchers can conduct experiments remotely, even automatically. Human applications for this are still some way off, but we're sure our future overlords will make good use of it.
Genius DX-ECO wireless mouse has no battery, charges in three minutes anyway
Hip on recharging your wireless rodent every single day? How about if it only takes three minutes? A single day's juice per charge might be unacceptable for most peripherals, but we're ready to make an exception for Genius' DX-ECO wireless mouse. This adjustable 800 / 1600 DPI clicker swaps out a recharge battery for a "gold," or electric double-layer capacitor -- you may know it as a super, or ultracapacitor. A step towards a battery-free existence not enough for you? Fine, bask in the knowledge that the DX-ECO also features a carpet, marble and sofa friendly "BlueEye" sensor. Read on for the official PR. Us? We're off to fantasize about battery free electric vehicles.
Dipping capacitors and batteries in nanotubes could improve capacity
Stanford researchers figured out that, by dipping electrodes for super capacitors in a solution of carbon nanotubes or a conductive polymer they could increase the charging capacity by up to 45-percent. The team started working with composite electrodes of graphene and manganese oxide, since manganese is cheap and plentiful, but were hamstrung by its low conductivity. The thin coating of more conductive material greatly boosted the capacitance of the electrodes, and thus their ability to hold a charge. Further tests are still required to find the actual energy density of the dipped electrodes, but lead researchers Yi Cui and Zhenan Bao are already working on a way to apply the same technique to batteries.
Motorola announces NYXboard QWERTY remote, super capacitor-based NYXgreen
Could we be seeing the beginning of a QWERTY trend in the living room? We can only hope -- the latest to join in on the fun is Motorola, which has just introduced its new NYXboard remote at IBC 2010. Unlike the TiVo Slide, this one packs a standard TV remote on one side and a QWERTY keyboard on the other, and -- here's the real kicker -- some sensors that recognize which side is facing up and deactivate the buttons not in use, an idea we've been waiting for. What's more, Motorola says this one will be available by the end of the year, but actual availability to customers will likely depend on the cable companies providing the set-top boxes. Also unveiled at the show is the NYXgreen, a rechargeable remote powered by super capacitors that can supposedly last for two weeks after being charged by USB for just 60 seconds, plus a pair of decidedly more standard remotes that are available immediately. Head on past the break for the press release, and hit up the gallery below for a look at the whole lot. %Gallery-101893%
