Finally, the bionic eye is a reality [timesonline]:
Surgeons have carried out the first operations in Britain using a pioneering “bionic eye” that could in future help to restore blind people’s sight…
The device — the first of its kind — incorporates a video camera and transmitter mounted on a pair of glasses. This is linked to an artificial retina, which transmits moving images along the optic nerve to the brain and enables the patient to discriminate rudimentary images of motion, light and dark.
A tiny chemical “brain” has been invented by Scientists at the National Institute for Materials Science in Tsukuba, Japan. With a size of two nanometers, the molecular device is capable of controlling eight of the microscopic nanobot machines simultaneously.
Research on artificial nerve grafting for treatment of patients with traumatic injuries of nerves in the arms and legs, organ transplants and the removal of tumors:
University of Manchester researchers have transformed fat tissue stem cells into nerve cells — and now plan to develop an artificial nerve that will bring damaged limbs and organs back to life.
In a study published in October’s Experimental Neurology, Dr Paul Kingham and his team at the UK Centre for Tissue Regeneration (UKCTR) isolated the stem cells from the fat tissue of adult animals and differentiated them into nerve cells to be used for repair and regeneration of injured nerves. They are now about to start a trial extracting stem cells from fat tissue of volunteer adult patients, in order to compare in the laboratory human and animal stem cells.

Some recent developments in the area of human-computer interface promise control of software [including game avatars, soundtracks, and more] via thoughts and emotional responses rather than keyboards or joysticks.
Emotiv Systems, an electronic-game company from San Francisco, wants people to play with the power of the mind. Starting tomorrow, video-game makers will be able to buy Emotiv’s electro-encephalograph (EEG) caps and software developer’s tool kits so that they can build games that use the electrical signals from a player’s brain to control the on-screen action… S.M.A.R.T. BrainGames, a company based in San Marcos, CA, sells games and EEG caps designed to treat people with attention deficit/hyperactivity disorder. [via Technology Review]
10. Sit up straight, and close your mouth: Good posture affects our state of mind, and helps us to think more clearly. Wanna prove it to yourself? Try solving some math in your head while slouching, looking at the floor and letting your mouth hang open. Then do the mental math while sitting up straight, keeping your mouth closed and looking forward or slightly upwards. You’ll get the point.
14. Make connections: To grow longer dendrites, do something new. Try learning a new language or developing a skill such as drawing, and you’ll see instant changes in how you think.
20. Graze: To give your brain a steady supply of energy and minerals, eat little and often. Eating large meals shunts blood to your digestive tract, away from your brain.
25. Make friends: Preferably ones with large amounts of frizzy grey hair. Recent research showed that hanging out with boffins can boost your IQ by up to 10 percent.
USC’s Ted Berger’s [”memory hacker“] research on brain-interface neurotechnology, neural modeling and biologically-inspired computing modules [funded by the National Science Foundation and the Defense Advanced Research Projects Agency] focuses on the potential for being able to one day:
open someone’s skull; implant a tiny, densely packed silicon computer chip; connect it to the brain; and let it take over cognitive function previously lost due to disease or injury.
“He wants to be the man who implants microchips between your ears. And the amazing thing is that he just might succeed,” a Wired magazine feature declared five years ago. Berger’s ambition to “create a bionic brain is bold, brash, and just a bit, well, mind-blowing,” the technology magazine opined. Berger’s project has come a long way since then.
This isn’t like a cochlear implant or an artificial retina or any other device stimulating inactive nerve fibers to resume functioning. No. This will be an artificial chunk of brain, something right out of a William Gibson cyberpunk thriller…
“We are on the brink of stretching the capabilities of the human race. I believe we will soon be able to connect the brain to computers or other devices,” Berger says. “We have to think about the implications.” [via USC and futurist.com]
Inventor Dean Kamen previews the extraordinary prosthetic arm he’s developing at the request of the Department of Defense, to help the 1,600 “kids” who’ve come back from Iraq without an arm (and the two dozen who’ve lost both arms). Kamen’s commitment to using technology to solve problems, and his respect for the human spirit, have never been more clear than in this deeply moving clip.
