In the story of life on Earth, there have been countless species that have come and gone over the course of billions of years. Life evolved from the simplest of single-celled organisms to the ...

The Environmental Protection Agency is worried about a lot of things in our water — polychlorinated biphenyls, dibromochloropropane, Cryptosporidium parvum — to name just a few of the dozens of ...

I always jump at the chance to learn about a new microbe, and I’ve got a soft spot for protists - you know, the little guys that live in pond scum. Recently, I ran across a group of protists called ...

Researchers investigating how single-celled organisms evolved to become multicellular stumbled across a strange phenomenon during their experiments: Single-celled eukaryotes called choanoflagellates, ...

What do humans and single-celled choanoflagellates have in common? More than you'd think. New research into the choanoflagellate genome shows these ancient organisms have similar levels of proteins ...

A team of scientists say they have found a new candidate for the origins of animal life, according to a study published in the journal Nature. It has long been thought by many biologists that the ...

When people die, our whole body dies with us. The heart stops pumping; the gut stops digesting; every cell that carries a person’s genetic blueprint eventually extinguishes, until their molecular ...

In a groundbreaking experiment, researchers have brought a mouse to life with the help of a single-celled organism that existed long before any multicellular animals walked the earth. Genetic research ...

Up-to-date computational pipeline characterizes G-protein-coupled receptor (GPCR) repertoires in the closest relatives of metazoans, providing a framework to investigate the evolutionary origins and ...
