Orange lichens could be a potential source for anticancer drugs, Emory researchers revealed in a new study. A pigment known as parietin found in the lichens was tested on acute lymphoblastic leukemia cells and found to have significantly reduced or prevented cell growth within 48 hours.
Climatologists didn't see this one coming. It looks like mosses, lichens, and blue-green algae are all major players in the Earth's complex and often-confusing carbon cycle. Now, new research has revealed how these organisms regularly release some of the most intense greenhouse gasses known to man, demanding more attention be pointed their way.
