Moving Prosthetic Arms Just by Thinking Until recently, the different movements of prosthetic arms — bending the elbow, turning the wrist and opening and closing the hand — all required separate motors. They were capable of very limited movement, and each to be separately activated. But that's not so any more. Gerald Loeb, Professor of Biomedical Engineering and Director of Medical Device Development at the University of Southern California, says there are now artificial arms that people can move by just thinking about it.
Trump's ethical conflicts pile up as transparency diminishes President Trump's refusal to reveal his income tax returns is just one example of a lack of transparency that could be hiding conflicts of interest.
