Scientists at Rensselaer Polytechnic Institute have created a robot-like avatar in the virtual world Second Life that isn't controlled by a person at a keyboard, but an artificial intelligence program.

Duke University engineers think they've made an important step towards developing robotic surgeons that operate independently. The robot they used in their experiments—which were just feasibility studies, and were not performed on real people—uses 3-D ultrasound as its eyes, and an AI program that processes the 3-D information it gathers to determine the robot's next steps.

Yes, there are some great robot fight scenes, nefarious villains, a few human interest plotlines, even characters that seem like genuine people, but the new movie Iron Man is really about the lab, and its ridiculously cool toys.

The days of lugging around and pulling out hefty guide books could be nearing an end: The eyePhone, a program currently being developed in Europe, uses a combination of satellite information, object-recognition software and Internet data to provide information on landmarks in a scene captured through a mobile phone's lens.

A neuroscience blogger recently uncovered this BBC special on the prospects of brain-machine mergers, and what it means for the future.

As a high-school student in the 1950s, John Koza yearned for a personal computer. That was a tall order back then, as mass-produced data processors such as the IBM 704 were mainframes several times the size of his bedroom. So the cocksure young man went rummaging for broken jukeboxes and pinball machines, repurposing relays and switches and lightbulbs to make a computer of his own design.

Within certain parameters, his computer was a success, flawlessly reckoning the day of the week whenever he dialed in a calendar date, but the hardwiring made it useless for anything else.
