Green Tea and Red Laser Attack Alzheimer's Plaques, University of Ulm Study

IT MAY sound like a strange brew, but green tea and red light could provide a novel treatment for Alzheimer's disease. Together, the two can destroy the rogue "plaques" that crowd the brains of people with the disease. The light makes it easier for the green-tea extract to get to work on the plaques. Andrei Sommer at the University of Ulm in Germany, and colleagues, have previously used red light with a wavelength of 670 nanometres to transport cancer drugs into cells. The laser light pushes water out of the cells and when the laser is switched off, the cells "suck in" water and any other molecules, including drugs, from their surroundings.
