The ability to analyze gene expression at the single-cell level—known as single-cell RNA sequencing (scRNA-seq)—has ...

Single cell organisms reproduce by cell division, on their own. They may live alongside other cells of the same species. An E. coli bacteria that forms a colony containing many thousands of E ...

Caulerpa taxifolia appears to be the world's largest single-celled organism. It can grow up to 30 cm long and has some unique properties that allow it to grow as a single cell. It has a large surface ...

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 ...

Like all complex organisms, every human originates from a single cell that multiplies through countless cell divisions.

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 ...

For the first time, scientists have demonstrated that an organism devoid of a nervous system is capable of learning. Biologists have succeeded in showing that a single-celled organism, the protist ...

In the single-celled organism, too, there are logical connections between different elements of the cell. Chemical signals are triggered and ultimately lead to a certain movement of the organism.

Too much of a good thing is no good at all. Living organisms enjoy sunlight—in fact, they need it to stay alive—but they tend to avoid light that is too bright. Animals go to their shelter ...

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 ...

It's a single-celled organism with no brain to speak of, but it's capable of solving mazes, maintaining a balanced diet, and even "designing" an efficient railway system.

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 ...
