A man with brain damage who's been stuck in a coma-like state for the past six years recently had electrodes implanted in his brain. While before the surgery he could only communicate via small finger an eye movements, he's now able to talk, eat, drink, and brush his hair. It's a huge step forward for treatment of people with brain damage and in a minimally-conscious state.
It's a pretty amazing development; before this, people would have counted him as a loss. Trapped inside his own head, he just needed the juice to get himself going again, and doctors are finally able to give it to him. Hopefully we'll see more advances in technology like this to help more injured people get back to some semblance of normalcy.
