Chromosphaera perkinsii is a single-celled species discovered in 2017 in marine sediments around Hawaii. The first signs of its presence on Earth have been dated at over a billion years, well before ...

MicroRNAs (miRNAs) — a class of small RNAs with a role in the regulation of gene expression — had until now been found only in multicellular organisms. Now, Wang, Qi and colleagues provide the first ...

An international team of researchers has achieved an unprecedented milestone: the creation of mouse stem cells capable of generating a fully developed mouse using genetic tools from a unicellular ...

A ubiquitous but little-known marine organism, the choanoflagellate, is the last one-celled ancestor of humans and provides insight into how cells learned to assemble into multicelled organisms. The ...

The oceans are home to innumerable creatures, from minute bacteria to the mighty blue whale. Amid this, there are various unicellular organisms which exist. These organisms have a single cell, which ...

Large, nutrient-poor expanses of the open ocean are getting a substantial nitrogen influx from an abundant group of unicellular organisms that "fix," or chemically alter, nitrogen into a form usable ...

The transition to multicellularity enabled the evolution of large, complex organisms, but early steps in this transition remain poorly understood. Here we show that multicellular complexity, including ...

If there is one process that a cell must do right, it is copying its DNA before division, and making sure that the chromosomes are distributed properly to the daughter cells. This is even more ...

Scientists at the University of Innsbruck have discovered over 30,000 viruses by using the high-performance computer cluster ‘Leo’ and sophisticated detective work (Proceedings of the National Academy ...

Images of the multicellular development of the ichthyosporean Chromosphaera perkinsii, a close cousin of animals. In red, the membranes and in blue the nuclei with their DNA. The image was obtained ...
