An anonymous reader writes, "Scientists have developed a virtual world like Second Life where real-life amputees have their limbs restored. The experience can cure patients of the perception of pain in their missing limbs. From the article: 'The machine is designed to combat phantom limb pain (PLP) — a sensation of pain experienced by an amputee that appears to originate in the missing limb. Intriguingly, researchers have discovered that if a person's brain can be tricked into believing they can see and move a "phantom limb," this motion reduces the perception of pain in PLP.' The graphics used by the computer look very crude, almost comically so, but apparently the system works."
