A chemical compound made from a type of bacteria discovered in the Florida Keys appears to be effective in fighting colon cancer in preclinical experiments.
The compound—known as largazole because it was first found near Key Largo—inhibits human cancer cell growth in cultures and rodent model... Read More
Drafting cyclists have nothing on spore-spewing fungi. Using an aerodynamic technique, a fungus can reduce drag on its spores—sending them high and far.
One fungus, the destructive Sclerotinia sclerotiorum, spews thousands of spores nearly simultaneously to form a plume that reduces drag to n... Read More
America's hospitals are places of healing and hope. But they're also home to a growing threat. You may have heard of MSRA - a dangerous infection that can often be treated with antibiotics.
