Scientists have shown that fuel cells implanted in rats can successfully generate electricity from sugar in the rodent's bodies. The devices kept going for months at a time."

"Boffins in America are working on biodegradable, flexible electronic devices printed on silk, which could be implanted in the human body and would decay naturally over time. Applications could include LED displays inlaid beneath the skin, or direct nerve-controlled interfaces."

"It's probably not a great idea to smoke while you do brain surgery and insert mind-control electrodes into little kids' heads."

"A "data cable" made from stretched nerve cells could someday help connect computers to the human nervous system. The modified cells should form better connections with human tissue than the metal electrodes currently used for purposes such as remotely co
