Paralyzed Man Walks Again After Brain Cells Are Injected into His Spine


Back in 2010, Darek Fidyka became paralyzed from the waist down after suffering stab wounds to his back. Now, after 19 months of treatment in which cells from his brain were transplanted into his spinal column, he can walk with a frame. Researchers are calling it a "historic breakthrough."
The new technique, the details of which now appear in the latest edition of Cell Transplantation, involve olfactory ensheathing cells (OECs), which come from a part of our brains that deals with the sense of smell. By transplanting them into Fidyka's spinal column, the neurologists were able to construct a "nerve bridge" between two stumps of the damaged spinal column.
"We believe... this procedure is the breakthrough which, as it is further developed, will result in a historic change in the currently hopeless outlook for people disabled by spinal cord injury," noted the study's lead author Geoffrey Raisman in a Reuters article. He's currently a professor at University College London's (UCL) institute of neurology.
Fidyka, who's 38 years old, has recovered some voluntary movement and some sensation in his legs. He's continuing to improve more than predicted, and he's now able to drive and live more independently.

The World’s First Mind-controlled Exoskeleton by George Dvorsky

http://io9.com/the-world-s-first-mind-controlled-exoskeleton-511251650

Wow, is this a taste of the future, or what? Check out MindWalker — an exoskeleton that will soon enable paralysed and locked-in people to walk using only their mind. Ah, who are we kidding — we're ALL going to eventually want this for ourselves!


The groundbreaking device, which is currently under review by the European Commission, consists of three main elements: The exoskeleton itself, a virtual-reality user interface, and the mind-reading component. It was developed by a consortium of several major universities and companies.

Users control the MindWalker using an EEG cap that measures electrical activity at various points across the scalp. There are a number of different ways to control the exoskeleton in this way, but the best model involves wearing a pair of glasses with flickering diodes attached to each lens.

Robots Can Learn To Hold Knives — and Not Stab Humans

"We humans enjoy not having knives inside of us. Robots don't know this (Three Laws be damned). Therefore, it's important for humans to explain this information to robots using careful training. Researchers at Cornell University are developing a co-active learning method, where humans can correct a robot's motions, showing it how to properly use objects such as knives. They use it for a robot performing grocery checkout tasks."
