A team of geomicrobiologists has detected a new microbe that survives in some of the most acidic waters on Earth, at a seemingly impossible pH near 0. That makes this critter, a member of the microbial kingdom Archaea, one of a few record-setting bugs that can survive in conditions usually toxic to life as we know it. The discovery of the microbe, dubbed Ferroplasma acidarmanus, is reported on page 1796.
