Just because I think this is really cool, a Newsweek link: a 41,000+-year-old tree, the only one ever found that carries in it a record of a reversal of the magnetic poles that help protect our ozone layer from the solar winds. Found way down there while digging for a geothermal plant for clean energy. And it still exists. Fascinating stuff.
