A technique inspired by the film Interstellar suggests a new way of communicating backwards in time, but it could help improve conventional communication systems as well ...
Researchers have developed a method for steering microscopic swimming robots using light patterns and the principles of Einstein's theory of relativity. The technology is a potential first step toward ...
