This is the first finding of microRNAs in a unicellular organism. An international collaboration of researchers, led by Dr. Yijun Qi (National Institute of Biological Sciences, China), report the ...

The first life forms to appear on Earth were unicellular, i.e., composed of a single cell, such as yeast or bacteria. Later, animals—multicellular organisms—evolved, developing from a single ...

Unicellular organisms, such as microalgae, also age when they can no longer divide due to a lack of nutrients. The newly discovered mechanism enables old cells to rejuvenate and divide again after ...

First identified about five years ago, these organisms – about 7 microns in diameter – are fixing nitrogen at rates up to three times higher than previously reported for the Pacific Ocean ...

the creation of mouse stem cells capable of generating a fully developed mouse using genetic tools from a unicellular organism, with which we share ... The origin of eukaryotes is considered one ...

However, most of the time they cannot become active because the unicellular organism usually only produces them together with an antitoxin that neutralizes their poisonous effect. This is a trick ...

Amid this, there are various unicellular organisms which exist. These organisms have a single cell, which contaians the DNA, cytoplasm and organelles required for survival. All major life ...

Chromosphaera perkinsii, a unicellular organism found in Hawaii, first appeared at least one billion years ago and underwent cell division to produce what resembled a precursor to eggs.

This trumpet-shaped organism is among the largest unicellular organisms, stretching as long as a sharpened pencil tip. But sometimes it has a hard time vacuuming up the swimming bacteria and ...

perkinsii), an ancestral species of protist. This unicellular organism separated from the animal evolutionary line more than a billion years ago, offering valuable insight into the mechanisms that ...
