A child in South Carolina has died after being infected with Naegleria fowleri, commonly referred to as brain-eating amoeba.

There are roughly a trillion species of microorganisms on Earth—the vast majority of which are bacteria. Bacteria consist of a single cell. They do not have bones and are not like big ...

The brain-eating amoeba, Naegleria fowleri, has been detected in some Louisiana waters. Here's what to know about brain infections caused by amoebas.

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 ...

Rare cases of Naegleria fowleri can result in a severe infection in the brain, with infection fatal in around 95% of cases.

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

Bacteria aren't the only single-celled organisms in town, however. Archaea are another type of single-celled organism that are known to carry flagella that can also behave like propellers. The ...

Almost all eukaryotic organisms, from plants and animals to fungi, can't survive without mitochondria -- the 'powerhouses of the cell,' which generate chemical energy using oxygen. However, a new ...

Eukaryotic cells evolved from simpler cells, like bacteria and archaea. The Asgard archaeal phylum is currently thought to be eukaryotes' closest known ancestor. Now researchers have found an enzyme ...

Every human, bird, tree, and flower can trace its ancestry across a few billion years back to microscopic, single-celled organisms such as bacteria. That change from micro to macro, ...
