USC starts a web hub for DIY, open source virtual reality projects
For the sheer variety of virtual reality headsets available, there's been few resources available for those who want to craft their own devices. USC wants to save us the effort of searching around. Its MxR Lab has just launched a showcase of creations and modifications that DIY enthusiasts can build, including open source code for both the devices and integrating full-body motion control through Kinect for Windows or OpenNI. The most ambitious is Socket HMD, a complete 1,280 x 800 headset that involves a 3D-printed shell and custom-assembled electronics. If your own ambitions don't stretch that far, you can still build the VR2GO viewer, which uses iPhones and iPod touch players as the eyepieces, as well as mods for the Oculus Rift developer kit that add stereo cameras or increase the field of view. Yes, you'll need a 3D printer and a knack for programming to get most of these projects going, but you won't have to wait for someone to make them for you -- a big help when many ready-made VR displays are either in development or priced out of reach for the average person.
Electrified bacteria army kills uranium, gives Captain Planet a run for his money
A certain type of "hairy" bacteria may just be the answer to cleaning up radioactive spills. Scientists at the University of Southern California found that under certain circumstances, Geobacter sulfurreducens could make metals like uranium less soluble -- essentially turning the metal into hard droplets rather than being absorbed. Researchers discovered that by lowering the bacteria's temperature, it caused hair-like pili to extend, which enveloped the poison uranium and ultimately reduced it through long-range electron transfer. The breakthrough could help deplete sources of uranium or other radioactive isotopes where bacteria normally can't survive -- like from the Fukushima nuclear plant that devastated Japan earlier this year. Scientists believe they've only scratched the surface with this development and are optimistic about the future of bacteria "electromicrobiology," which we can only guess grew in popularity after this '80s classic hit the airwaves (video after the break).
