GameKeyboard 2.0 requires root, maps Xperia Play gamepad to all Android games (video)
Upon its debut, the Xperia Play suffered from a lack of game titles that were compatible with its unique built-in gamepad. While the selection has improved considerably since its inception, the question remains: wouldn't it be nice if the handset supported any Android game you threw at it? Wonder no longer, because that's exactly what GameKeyboard 2.0 brings to the table. Yes, the app requires root access, but most importantly, it allows users to map on-screen touch controllers to the Xperia Play's physical gamepad. While it's slightly cumbersome to setup for the first time, anybody who has ever configured an emulator with a USB game controller will feel right at home. GameKeyboard 2.0 sells for $2.49 in the Play Store, and if you'd like a quick overview of how it all works, just hop the break for a video. Those who proceed with the download will also benefit from written instructions (for both root access and configuration) in the xda-developers forums.

Adidas MiCoach game launching this summer, headed to Xbox 360 and PS3
Despite being involved in that peaceful conundrum with THQ, we knew Adidas still planned on launching its MiCoach video game at some point in the near future. Now, after weeks of keeping those lips sealed, the German company announced it's teaming up with publisher 505 Games to finally bring the fitness-driven title to the Xbox 360 and PlayStation 3 -- where it'll primarily use the Kinect and Move add-ons. While 505 will handle all publishing duties, Adidas notes the MiCoach game is in the works by UK developer Chromativity "under exclusive license." Of course, the F50 creator couldn't leave its big name reps out of this one, which is why sport celebs like Kaká, José Mourinho and Dwight Howard are going to be teaching "Masterclasses" within the game. Hey, at least now you know you won't have to be out on the field to put that tracking system to good use.

Khloe Kardashian: "Divorce Is Not an Option"
Khloe Kardashian is prioritizing being a good wife over being a good reality TV star, and for that we respect her. The 27-year-old is putting her TV show on hold in order to help get hubby Lamar Odom's basketball career back on track.

Conquering LED efficiency droop
ScienceDaily (Apr. 30, 2012) ? Like a coffee enthusiast who struggles to get a buzz from that third cup of morning joe, light-emitting diodes (LEDs) seem to reach a point where more electricity no longer imparts the same kick and productivity levels-off. Now a team of researchers from California and Japan has devised a new design for green and blue LEDs that avoids much of this vexing efficiency droop. The findings will be presented at the Conference on Lasers and Electro-Optics (CLEO: 2012), taking place May 6-11 in San Jose, Calif.
By changing the orientation of the crystal structure in semiconductor films, the team created LEDs with high efficiency and extremely low droop. Droop, which is a dramatic drop in efficiency at high currents, is one of the main problems limiting the growth of the solid-state lighting market.
Blue and green LEDs provide the essential hues that blend with other wavelengths to give us the familiar white light we expect from household bulbs. These highly prized colors, however, have been among the hardest to engineer and the "droopiest" of the LEDs.
"We believe this technology could be a big breakthrough and has the potential to change the future of lighting," says Yuji Zhao, a graduate student at the Solid State Lighting and Energy Center at the University of California Santa Barbara (UCSB) and one of the lead researchers on the team.
LEDs are many times more energy efficient than heat-spewing incandescent bulbs, but, due to droop, lose a significant fraction of that efficiency at the high current levels required for typical household lighting. No one is exactly sure what causes droop, although different research groups have offered several competing explanations. Despite the uncertainty, the UC Santa Barbara-based research team has developed a promising technique to minimize droop by making changes to the way the LEDs are manufactured.
LED chips are made from layers of doped semiconductors sandwiched together. When a voltage is applied across the layers, electrons and holes (an absence of electrons) migrate toward an area of the LED called the active layer, where they combine, begetting a photon in the process. In most commercially available blue LEDs, the crystals that make up the semiconductor layers are grown in a flat orientation called the c-plane. This traditional orientation of the crystals, however, may create electrical fields that interfere with the reunion of the electrons and holes.
The UCSB researchers' LEDs have non-traditional, tilted crystal orientations that lessen the effect of the field, and exhibit some of the lowest reported measures of droop. Using this approach the team was also able to fabricate LED chips that are smaller than standard commercial LEDs, which could cut down on manufacturing costs.
Further work remains to be done. "The biggest problem right now is the relatively high cost of the gallium nitride [GaN] bulk substrates," says Zhao, referring to the thin sheets of crystalline material on which the group's LEDs are grown. "At UCSB we are also developing methods to mass produce high quality GaN bulk substrates. I have confidence in this and I think it's just a matter of time before [the cost of GaN] will no longer be an obstacle."
