Fixing what you lost

Science and technology are working to bring solutions to those who lose limbs, or are at risk of limb amputation.
Yes, solutions, as in plural.

In the prosthetics world, neurologists and engineers have created a robotic arm that connects to your neural (electrical) network through a brain-machine interface. Yes, right now the hand on the arm does kind of remind one of a Daleks', but it's a start. Now that the mechanics work, it's only a matter of time before they pretty it up and model it as a human limb.

On the other hand - har, har - biological engineers have continued their progress to regrow bone, and bone-like substances, to heal and recreate lost limbs or sections of bone. I first saw this in 2007 when scientists made a breakthrough on growing bone from stem cells. As late as 2010, scientists were able to regrow a whole section of a mammal's leg.
It's such a wonder to live in the day and age, right on the birth of such medical breakthroughs. Imagine how these technologies will help not only accident victims, bone disease sufferers, but our war veterans.

  1. We've sure come a long way from the first prosthetic to now. I remember a showcase of bionics 30 odd years ago.
