Microbial activity in the deep continental subsurface is difficult to measure due to low cell densities, low energy fluxes, cryptic elemental cycles and enigmatic metabolisms. Nonetheless, direct access to rare sample sites and sensitive laboratory measurements can be used to better understand the variables that govern microbial life underground. In this study, we sampled fluids from six boreholes at depths ranging from 244 m to 1,478 m below ground at the Sanford Underground Research Facility (SURF), a former goldmine in South Dakota, United States.

"How much science and technology do you see in the mass media? Every newspaper has a daily astrology column. How many have even a weekly science column?" he asked, lamenting the limited science coverage in newspapers.

In a hydrogen-based economy future, hydrogen leakage is becoming an environmental concern. Ruminants naturally produce small amounts of hydrogen, which is emitted in the environment along with other fermentation gases, such as the GHG methane and carbon dioxide. Here, for the first time, we estimated hydrogen emissions from the global ruminant livestock at 527 kt/yr (95% CI: 399, 654), or about 3.
