Well, not quite yet, but we’re getting closer. Years of study have demonstrated over and again that there is huge potential in the concept of a mind-machine interface, allowing people to communicate with, and control, computers using only their thoughts. Past experiments have shown how it’s possible to control robotic arms and legs using the same parts of your brain that control your real arms or legs. Not only does this technology hold a lot of promise for handicapped people – imagine a paraplegic being given robotic legs to replace his originals – but it has also led to a series of really cool videos of monkeys.

Your body is naturally equipped with a highly skilled defense force, complete with advanced targeting systems, devastating weaponry, and specially-trained assassins. It is this force that protects you from invaders and attackers trying to force their way in and wreak havoc with your body. But this system isn’t flawless, and those pesky pathogens can be crafty, and every now and then, one of them sneaks by. This is where medical science comes in. Medicine is the cavalry, designed to give your body’s natural defenses a helping hand in warding off nature’s more resilient marauders.
Sometimes an enemy comes along that your body really needs some help with. Not every disease is as docile as a rhinovirus. Way toward the top of Medicine’s Most Wanted list is HIV, the virus that causes AIDS, responsible for the deaths of well over a million people a year. A vaccine for combating HIV has evaded medical science for years, but recent research brings new hope to the battle.
