One significant area in biotechnology, the magazine highlights, is work on brain-machine interfaces that could someday allow people to control artificial devices that replace lost functions. Today, research is more limited, with scientists able to take signals from individual neurons in an animal's brain and send them to a robot that can turn the signals into motion. But the potential is huge, according to Duke University neurobiologist Miguel Nicolelis.
