Toxic tide

In the Gulf of Mexico lurk menacing masses of single-celled organisms known as red tides. Scientists have long known that the potent toxin they produce can kill fish and birds, wreak havoc on the human nervous system and cause wheezing, sneezing and asthma flare-ups. But new research suggests that it can also damage DNA, which could lead to more subtle, longer-term health consequences.
