Single cell organisms can be parasites that can't grow outside another living organism. The syphilis bacterium, Treponema pallidum, doesn't normally grow outside of animal bodies.

Scientists continue to inch closer and closer to medical breakthroughs by tinkering with DNA. At the end of 2016, the CRISPR gene-editing tool was used for the first time on human cancer patients ...

Every day, our bodies perform around 330 billion cell divisions to keep us alive and functioning. These divisions rely on the cell cycle, which has been in place since the earliest bacteria. The ...

It has been widely assumed that, in single-celled organisms, each cell perceives its environment -- and responds to stress conditions -- individually. Likewise, it had been thought that cells in ...

Holozoans are a group of organisms including animals and their closest single-celled relatives. The fossil organism is still very simple, resembling a blob of cells with a diameter of just 5 to 20μm.

Researchers have created a synthetic single-celled organism (not pictured) that can divide properly. vjanez/Depositphotos. 2 / 2. A microscope image of the synthetic JCVI-Syn3A cells dividing.

I became interested in how adult stem cells help an organism sustain homeostasis. Most of the time, these stem cells aren’t doing much; they’re maintaining a low metabolism, and it’s almost like they ...

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 ...

Scientists announced Thursday that they have built a single-celled organism that has just 473 genes — likely close to the minimum number of genes necessary to sustain its life. The development, they ...

A single-celled organism closely related to animals controls its life cycle using a molecular toolkit much like the one animals use to give their cells different roles, scientists report October ...
