Chocolate isn't usually on the diet for snails, but when Lee Fruson and Ken Lukowiak from the University of Calgary, became curious about the effects of diet on memory, they decided to try a flavonoid from chocolate, epicatechin (epi) on the pond snail Lymnaea stagnalis to see if it improved the animals' memories. After a dose of epi, the pond snails were able to remember a training protocol for longer and the memories were stronger. http://phys.org/news267896167.html Biology Thu, 27 Sep 2012 00:20:01 EST news267896167 A compound found in green tea could be a weapon in treatments for tackling cancer, according to newly-published research at the University of Strathclyde in Glasgow, Scotland. http://phys.org/news264850413.html Nanotechnology Wed, 22 Aug 2012 10:33:41 EST news264850413 A compound found in green tea shows great promise for the development of drugs to treat two types of tumors and a deadly congenital disease.
