Protists such as this Euplotes are common in water, soil, even moss. Scientists say a few simple measures of a protist’s cell size and shape can be powerful predictors of how they might respond to ...

A new National Science Foundation (NSF) grant will support a major effort to synthesize decades of research on protists—microscopic organisms that play a vital role in aquatic ecosystems but remain ...

Nikon announced the winners of their annual Small World in Motion competition today and the winning video is a detailed look at the microscopic creatures that help termites digest wood. Still from ...

Is there a more deceivingly attractive collection of organisms than the protists? At a microscopic level, the protists are some of the most beautiful cells on earth, but what a collection of woes they ...

In the natural world, organisms and their environments are locked in a constant conversation. Termites build nests that alter ...

Protists, a broad class of generally single-celled organisms that includes algae and amoebae, have long been regarded as a “catch-all” category for diverse microorganisms. Because of their diversity ...

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 ...
