Brightly colored beetles or butterfly larvae nibbling on a plant may signal the presence of chemical compounds active against cancer cell lines and tropical parasitic diseases, according to researchers at Smithsonian's Tropical Research Institute in Panama. Such clues could speed drug discovery and provide insight into the ecological relationships between tropical-forest plants and insects that feed on them. The report is published in the Ecological Society of America's journal Frontiers in Ecology and the Environment. http://www.physorg.com/news134756257.html Biology Tue, 08 Jul 2008 17:17:37 EST news134756257
