Because they rely on hosts for a majority of functions, viruses aren’t considered alive. But entities like this one ...
In the vast and often unseen world of microscopic life, a recent discovery may force scientists to rethink what it means to ...
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 ...
Most organisms fit comfortably into standard definitions of “life,” i.e., cells that grow, reproduce independently, and ...
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 ...
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 ...
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.
Scientists have sequenced the complete genome of a roundworm used extensively in biological research, opening a new pathway ...
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.
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 ...
Large swaths of single-celled eukaryotes, non-bacterial single-cell organisms like microalgae, fungi or mold, can control microbiomes (a collection of tiny microbes, mostly bacteria) by secreting ...
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 ...
