Synthesized molecule holds promise as antitumor agent
Amphidinolides, a family of natural compounds that have shown promise as powerful antitumor agents, pose problems for cancer researchers because they are found in only minute amounts, and only in microscopic marine flatworms that live off the coasts of Japan and the U.S.

Scientists solve chaotic heartbeat mystery
A team of scientists headed by UMBI's Jonathan Lederer in Baltimore have discovered that a mutation in a protein in heart cells causes a condition called LQT4 in which heartbeats act chaotically and healthy people can die suddenly.
