Guinness is Good for You - and Someday, the Planet

Guinness is not only good for you — in the near future, it could be good for the environment, too.

Researchers at the University of Limerick in Ireland looking at canned stouts recently discovered that "microscopic plant fibers made of cellulose, such as cotton, can also froth up a stout."

A cellulose alternative to the plastic widget currently used in those cans would thus create "an eco-friendly head on your Guinness."

Think of it as the 'right' sort of green beer — as opposed to the to-dye-for wrong sort.
