POPSi-Limb, the bionic hand Reynolds said: "Sometimes I forget how cool that is. But then I show people how it works and I think, wow! Actually that is really amazing." i wonder if one day it will become stronger and more accurate than the biological hand. And then what?

POPSAn End to Paralysis with Artificial Brain-to-Muscle Connectors Say the researchers: Until now, brain-computer interfaces were designed to decode the activity of neurons known to be associated with movement of specific body parts. Here, the researchers discovered that any motor cortex cell, regardless of whether it had been previously associated with wrist movement, was capable of stimulating muscle activity. This finding greatly expands the potential number of neurons that could control signals for brain-computer interfaces and also illustrates the flexibility of the motor cortex. Human implementations for the technology are at least a decade away, but this discovery could be a game-changer for dealing with paralysis. One possibility would be to connect the motor cortex with an area of the spine below an injury. Signals would be re-routed around the damaged spinal cord, and could allow the brain to regain control of the paralyzed body parts affected by the injury.

POPSBionic implants raise ethical question What's the difference between a bionic ear, and an artificial leg, a kidney dialysis machine a heart valve or a breast implant ? They're all artificial substitutions. I have trouble finding the reason for anyone but the recipient to judge. As for the fear of 'superhuman' capabilities It is just a matter of taking the next step and substituting the brain. Then there's a robot/cyborg with absolutely no ethics, just a command chain, but a chain is only as strong as it's weakest link. When is the public ever listened to anyway ? Perhaps we should ask a deaf philosopher.

POPSNew, bionic hands available to Iraq vets I'm sure they'd rather have the hands they were born with, but at least the government is trying to relieve some of the trauma of having a hand blown off by giving them a super-duper replacement.
