The Microbial Soil Process That Controls Atmospheric Hydrogen

There are many enduring mysteries regarding the composition of the Earth's atmosphere but one may be a little closer to being solved. Researchers have discovered a microbial soil process that helps ensure that the explosive gas hydrogen remains at trace levels.  In recent decades it was found that about 80 percent of all hydrogen released into the air is rapidly removed through soil activity, but exactly what is recycling it, and how, has remained unclear. read more
