Toxic blue-green algae may provide new anti-cancer drugs

A collaborative team of researchers spearheaded by Dennis Carson M.D., professor of medicine and director of the Rebecca and John Moores UCSD Cancer Center at the University of California, San Diego (UCSD) has identified a potent new anti-cancer drug isolated from a toxic blue-green algae found in the South Pacific.
