A Big Step (Maybe) For Biofuels

Cellulosic ethanol (aka ceetol) is really the gold standard of biofuels because it is almost carbon-neutral and doesn't require diversion of arable land. It's tough to produce in a cost-competitive manner, though, mostly because cellulose is tough stuff. This discovery may turn out to be a key step in making ceetol the preferred energy source of the second half of this century.
