Researchers found that cooperative fluid dynamics between single-celled organisms may have driven the evolution of multicellular life.

Single-celled organisms that group together can generate stronger water currents to pull in food, a benefit that may have encouraged early life forms to assemble into colonies, according to a new ...

P. lunula is an example of a dinoflagellate—a single-celled organism that cannot move on its own. Its main source of energy is sunlight: similar to plants, it uses a structure known as a ...

A new part of an ocean plant cell has been discovered that might revolutionize farming one day. The structure can take nitrogen and convert it into the ingredient that helps all organisms grow.

An curved arrow pointing right. A single celled organism eating its prey, an inside view of a termite's gut, and a parasite going 'Alien' on its host took top honors in Nikon's Small World in ...

Lacrymaria olor is a single-celled organism, or protist, that lives in fresh water and hunts its prey with its extraordinarily extendible neck-like protrusion. Its name means "tear of a swan ...

The fluid dynamics of cooperative feeding may have sparked single cells to assemble into complex, multicellular life, as illustrated by pond-dwelling trumpet-shaped, single-celled giants.

There are roughly a trillion species of microorganisms on Earth—the vast majority of which are bacteria. Bacteria consist of ...

The physics of how a quirky pond organism filters the water for food provides new insights into a possible driver of early evolution.
