Bile acids play a critical role in the emulsification of dietary lipids, a critical step in the
primary function of the small intestine, which is the digestion and absorption of food. Primary …

Facing the challenges of climate change, policy making relies on sound greenhouse gas
(GHG) budgets. Rivers and streams emit large quantities of the potent GHG methane (CH 4) …

Nitrate pollution of freshwaters and methane emissions into the atmosphere are crucial
factors in deteriorating the quality of drinking water and in contributing to global climate …

How microbial metabolism is translated into cellular reproduction under energy-limited
settings below the seafloor over long timescales is poorly understood. Here, we show that …

Dengue fever is caused by four related dengue virus serotypes, DENV-1 to DENV-4, where
each serotype comprises distinct genotypes and lineages. The last major outbreak in Mexico …

Soil bacteria-fungi interactions are essential in the biogeochemical cycles of several
nutrients, making these microbes major players in agroecosystems. While the impact of the …

Oxygen minimum zones (OMZs) are hot spots for redox-sensitive nitrogen transformations
fueled by sinking organic matter. In comparison, the regulating role of sulfur-cycling …

Beneath the seafloor, microbial life subsists in isolation from the surface world under
persistent energy limitation. The nature and extent of genomic evolution in subseafloor …

Ticks are important vectors of various pathogens that cause infectious diseases in humans.
Endosymbiotic bacteria have been explored as targets for tick and tick-borne disease …
