Learn how one-celled organisms, or single-celled organisms, helped build complex life.

While mirror bacteria may sound like a fun time, a group of 40 renowned scientists conclude it is probably not worth the risk.

The mystery of how multicellular life evolved has long baffled scientists, who've spent years trying to understand how solitary single-celled organisms began living in unison and triggered the ...

Scientists at Nagoya University in Japan have identified the genes that allow an organism to switch between living as single cells and forming multicellular structures. This ability to alternate ...

In fact, why and how multicellular life evolved has long puzzled biologists. The first known instance of multicellularity was about 2.5 billion years ago, when marine cells (cyanobacteria) hooked up ...

Scientists at Nagoya University in Japan have identified the genes that allow an organism to switch between living as single ...

Biobots could one day be engineered to deliver drugs and clear up arterial plaque. Kriegman et al. 2020/PNAS, CC BY-SA Life and death are traditionally viewed as opposites. But the emergence of new ...

A new study shows that multicelled organisms like the metazoan daphnia (pictured) require a tenfold increase in energy compared with protists for their growth, maintenance and survival. The high cost ...

Life and death are traditionally viewed as opposites. However, the emergence of new multicellular life forms from the cells of a dead organism introduces a “third state” that lies beyond the ...

Scientists at Nagoya University in Japan have identified the genes that allow an organism to switch between living as single cells and forming multicellular structures.

Stentor coeruleus is a giant unicellular, filter-feeding protist that uses the coordinated motion of its oral ciliary structure to generate feeding currents. These currents allow the organism to ...
