New genetic evidence builds the case that single-celled marine microbes might chow down on viruses. By Katherine J. Wu On the dinner plate that is planet Earth, there exists a veritable buffet of ...

Researchers from the Earlham Institute, in collaboration with the Department of Biology at the University of Oxford, have discovered three previously unrecognized lineages of the protist Bodo, each ...

The typical human digestive tract is home to one of the densest communities of microorganisms on the planet. Bacteria dominate researchers’ attention, with the roles of other members of this ecosystem ...

Marine protists encompass a vast array of unicellular eukaryotes that form the foundation of oceanic food webs and drive global biogeochemical cycles. Recent advances in environmental sequencing and ...

Eating and being eaten is a normal process in nature. These predator–prey dynamics help to stabilize ecosystems. It ensures that individual species do not become too abundant, controls their ...

Tiny unicellular creatures called protists could keep greenhouse gases out of the atmosphere by gobbling up bacteria that emit CO2, researchers say. Now, a study finds that a few simple measures of a ...
