Mitochondria are very well known as the powerhouses of the cell. Generally speaking, all eukaryotes, including plants, fungi, and animals, are made of cells that contain mitochondria. These organelles ...

Protists are predators of bacteria, and they help shape soil communities by munching on bacteria (sorry, bacteria). Researchers knew that protists could identify prey when they were in direct contact ...

Viruses occur in astronomic numbers everywhere on Earth, from the atmosphere to the deepest ocean. Surprisingly, considering the abundance and nutrient-richness of viruses, no organisms are known to ...

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 studied in detail the strange protist Meteora sporadica, which swings its two lateral arms back and forth. The results of the study indicated that M. sporadica has a complex cytoskeleton ...

Scientists testing a new method of sequencing single cells have unexpectedly changed our understanding of the rules of genetics. The genome of a protist has revealed a seemingly unique divergence in ...

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 ...

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 ...

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 ...
