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 ...

Groove-like tracks on the ocean floor made by giant deep-sea single-celled organisms could lead to new insights into the evolutionary origin of animals, according to biologists. Groove-like tracks on ...

While testing a new way to sequence genes, researchers stumbled upon a very rare divergence in the genetic code, which translates genetic sequences into proteins. The discovery was made in an organism ...

On the seafloor near the Bahamas, researchers have discovered a single-celled organism about the size of a grape, and they say the unusual organism raises interesting questions about the evolution of ...

Scientists testing a new method of sequencing single cells have unexpectedly changed our understanding of the rules of genetics. The genome of a protist has revealed a seemingly unique divergence in ...

A series of mysterious spherical fossils found in southern China may be remnants of some of the world's earliest animals. A new study finds that these controversial fossils are not likely to be ...

The temperature-size rule (TSR) is an intraspecific phenomenon describing the phenotypic plastic response of an organism size to the temperature: individuals reared at cooler temperatures mature to be ...

AUSTIN, Texas—Groove-like tracks on the ocean floor made by giant deep-sea single-celled organisms could lead to new insights into the evolutionary origin of animals, says biologist Mikhail "Misha" ...
