Head transplants has been tried before. In 1970, Robert White led a team at Case Western Reserve University in Cleveland, US, that tried to transplant the head of one monkey on to the body of another. The surgeons stopped short of a full spinal cord transfer, so the monkey could not move its body. Despite Canavero's enthusiasm, many surgeons and neuroscientists believe massive technical hurdles push full body transplants into the distant future. The starkest problem is that no one knows how to reconnect spinal nerves and make them work again. "This is such an overwhelming project, the possibility of it happening is very unlikely," says Harry Goldsmith."
Ericsson predict that 5G's latency will be around one millisecond - unperceivable to a human and about 50 times faster than 4G.
