In a first-of-its-kind study, a team of researchers led by geoscientist Michael Rawlins at the University of Massachusetts ...

A sweeping new study reveals that as Arctic permafrost thaws, it is dramatically reshaping rivers and releasing vast amounts ...

While snowmelt is a major contributor to river flow, thawing permafrost is becoming increasingly important. Beneath the ...

Global change driven by anthropogenic pressures has profoundly affected ocean biogeochemical cycles. Natural fluxes have been disrupted due to imbalances, often in excess, of key elements like carbon, ...

The Earth's land surface is dominated by sloping landscapes. Every year, soil erosion laterally distributes on the order of 75 Gt of topsoil (Berhe et al. 2007). The coupled biogeochemical cycles of ...

Researchers have identified a previously unknown group of bacteria, called UBA868, as key players in the energy cycle of the deep ocean. They are significantly involved in the biogeochemical cycle in ...

We all know Earth is special, but we may not fully appreciate how good we have it on this planet. Unlike its planetary neighbors, Earth has remained habitable for billions of years thanks to a ...

Key PointsBacteria actively sense their environment and use chemical cues to navigate their world through a process called chemotaxis.Chemotaxis aids ...
