A team of British researchers has learned that gribble have a gift for digesting wood not seen in any other organism. Enzymes produced by the tiny creatures are able to break down woody cellulose and turn it into energy-rich sugars. This excites scientists investigating green fuel sources because it means gribble could hold the key to converting wood and straw into liquid biofuel.You learn something every day.
