It is a major area of plasma physics research that attempts to harness such reactions as a source of large scale sustainable energy. Fusion […]
Researchers have successfully used a wireless connection to transmit signals from a paralyzed monkey’s brain to control its legs. They say it’s now at least conceivable to use such a technique on humans. The aim is to treat people with damaged spinal cords that mean the brain can’t pass on electrical signals that act as instructions […]
