Dyne09 writes "The BBC is running a video report about a group of Swiss and Italian scientists who have created the 'Smart Hand,' a robotic hand with forty sensors that 'connect directly to the brain.' Though fuzzy on the details, the report says the hand provides sensor feedback to a willing test subject, a 22-year-old man who lost his hand to cancer three years ago. How long until we have access to Star Wars-esque robotic limbs?"
Today's scientific question is: What in the world is electricity?
And where does it go after it leaves the toaster?
