		<description><![CDATA[Horseradish, onions and caffeine all activate a group of chemical receptors that can trigger a pain signal. Turns out the same receptors exist in fruitflies, mussels, corals and mule deer. Why has this receptor survived a half-billion years? Because it protects against toxic chemicals - even if they taste good in small doses!]]></description>
