A research team at Ohio University has enabled a man suffering from quadriplegia to regain partial use of his right hand, using signals recorded by an implant that was surgically placed in his brain. "For the first time, a human with quadriplegia regained volitional, functional movement through the use of intracortically recorded signals linked to neuromuscular stimulation in real-time," the study’s text proclaims.

Ian Burkhart, now 24, broke his neck six years ago in a swimming accident, resulting in his paralysis. Two years ago, he underwent the procedure to have an implant inserted into his brain’s motor cortex, where the device picks up on the signals that would ordinarily be sent to the rest of his body to activate his muscles.

Scientists have managed to repair the injured hearts of living mice by reactivating long dormant molecular machinery found in the animals’ cells, a finding that could help pave the way to new therapies for heart disorders in humans.

For instance, men metabolize sleeping pills faster than women do, meaning that they knock women out more quickly and completely. The FDA is recommending different types of sleeping pills for each sex.
