Researchers in Australia are working on helping those in the world who suffer from chronic back pain with a chip that'll block that pain from reaching the brain. They've yet to try the device on humans, but they're confident that it'll work. I should hope so! Also this sort of thing frightens me. What happens if you get a giant stick jabbed into your back and you can't feel it? What then, science? You'll have stick-back syndrome. But this device will be more precise than all that - blocking only the pains that are useless to the human brain, the kind that never go away.
