Poisonous caterpillars are out to ruin the Olympics

While authorities in London are busy setting up missile launchers on top of residences in anticipation of perceived threats to this summer's Olympics, the real threat may already be lurking in the city's oak trees: Experts warn that oak processionary moths could be spreading to parts of East London. When in their caterpillar stage, the little creatures are covered in toxic hairs that can stir up reactions such as skin and throat rashes, watery eyes, vomiting, dizziness and even asthma attacks. While officials have destroyed upward of 700 nests, they fear the pests will be widespread across South East England in five years. You know what they say about moths being drawn to flame -- and the Olympic Games have a mighty big one.
