This research suggests that these single-celled organisms are able to make a decision and change their reaction. "Protists have to operate in complex ecological environments and naturally exhibit ...

Single-celled organisms apparently manage this feat without any problems: for example, they can swim towards food with the help of small flagellar tails.

New research from Harvard suggests some single-celled organisms may be capable of more complex decision-making than we give them credit for. In experiments, they were found to consult a hierarchy ...

Scientists have sequenced the complete genome of a roundworm used extensively in biological research, opening a new pathway ...

One of the largest single-celled organisms on Earth, however, can be about the size of the human eye. In fact, it is known as the ‘Sailor’s Eyeball’ because of its size and the fact that it can be ...

Most animals require brains to run, jump or hop. The single-celled protozoan Euplotes eurystomus, however, achieves a scurrying walk using a simple, mechanical computer to coordinate its microscopic ...

Physarum polycephalum is an unusual single-celled organism that can grow to be several square feet in size. These massive cells can live in cool, damp areas in temperate forests, and are able to ...

E. coli is arguably the most well-studied organism on Earth, but scientists have now discovered a new behavior that’s almost never seen in bacteria. The normally single-celled organisms have ...

More than 100 years ago, zoologist Herbert Spencer Jennings described surprisingly varied avoidance behaviors in the single-celled freshwater protist Stentor roeseli. When later experiments in a ...

Imagine a one-celled organism the size of a mango. It’s not science fiction, but fact: scientists have cataloged dozens of giant one-celled creatures, around 4 inches (10 centimeters), in the ...
