CRISPR-enabled control of gene expression sets the isotopic composition of microbial methane Open
The stable isotopic composition of biogenic methane varies substantially in the environment and is routinely used to fingerprint its source. However, the underlying cause of this variation is debated. Here, we experimentally manipulate the…

Hydrological control of rock carbon fluxes from shale weathering Open
Shale bedrocks hold Earth's largest carbon inventory. Although water is recognized for cycling elements through terrestrial environments, understanding how hydrology controls ancient rock carbon (Crock) release is limited. Here we measured…

Studying the isotopic composition of microbial methane with a genetically-tractable methanogen Open
Nearly all biogenic methane is produced by a group of microorganisms called methanogenic archaea (or methanogens). Methanogens can use a variety of substrates, such as H 2 + CO 2 , acetate, and methylated compounds, for methanogenesis. Pre…
