Glowing Bandaid

Scientists have unveiled a revolutionary sticking plaster that can kill off skin cancer cells. The technology uses OLEDs, or organic light-emitting diodes, to zap tumors, and can also heal conventional wounds. And, unlike existing skin cancer treatments, which usually take place in hospital, the OLED band-aid will allow the disease to be treated while the patient is at home — or work.

Carbohydrate-Based Medicine

Scientists from Germany today reported a major advance toward opening the doors of a carbohydrate-based medicine chest for the 21st Century. Much more than just potatoes and pasta, these carbohydrates may form the basis of revolutionary new vaccines and drugs to battle malaria, HIV, and a bevy of other diseases. Peter H. Seeberger, Ph.D., described development of an automated carbohydrate synthesizer, a device that builds these intricate molecules in a few hours — rather than the months or years required with existing technology.

A laser that stitches the skin

A doctor from Tel Aviv University demonstrated how a new laser the university has developed is better than stitching up a patient. The laser allows a wound to be welded shut as opposed to sutured, which makes it far more watertight and there's less tearing.
