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

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

An area of Alaskan permafrost the size of Greece is thawing, reveals new research. Arctic and global climate patterns may ...

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 ...

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