Environmental science has clearly entered the ‘era of the microbe’ during the past decade. At no other time in our history have we so completely grasped the immensity of microbial diversity or its ...

A procedure has been developed for preparing living bacteria, quantitatively labeled with 3 H-thymidine and 14 C-leucine, for short-term grazing experiments. The negligible rate of accumulation in ...

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 ...

Endosymbiosis between protists and bacteria represents a fundamental biological phenomenon that has shaped the course of eukaryotic evolution. These intimate associations, in which one organism ...

Groove-like tracks on the ocean floor made by giant deep-sea single-celled organisms could lead to new insights into the evolutionary origin of animals, according to biologists. Groove-like tracks on ...

The Rhizaria is a super-group of amoeboid protists with ubiquitous distributions, from the euphotic zone to the twilight zone and beyond. While rhizarians have been recently described as important ...

More than 100 years ago, a zoologist by the name of Herbert Spencer Jennings described surprisingly complex and varied avoidance behaviors in a single-celled freshwater protist known as Stentor ...

Since the Victorian era, categorizing the natural world has challenged scientists. No group has presented a challenge as tricky as the protists, the tiny, complex life forms that are neither plants ...

On the dinner plate that is planet Earth, there exists a veritable buffet of viruses — an amount of biomass that is the equivalent of about 25 billion human beings. So perhaps it’s a bit baffling that ...
