In a stunning scientific breakthrough, researchers from the University of California, Berkeley have discovered a living fossil in one of California’s untouched mountain lakes—a microscopic, ...

But complex multicellular organisms have arisen just six times on the tree of life: plants, animals, two groups of fungi, and two groups of algae.

Research from the University of Chicago provides a new view into key innovations that allowed modern, multicellular animals to emerge. By analyzing the proteins predicted from the genomes of many ...

Multicellular organisms can grow much larger than those with only one cell — as long as they can deal with the other effects of largeness.

Animals, from worms and sponges to jellyfish and whales, contain anywhere from a few thousand to tens of trillions of nearly ...

Modern-day environments in Antarctica contain ponds filled with life forms that closely resemble early multicellular ...

Research shows that there may be a third state between life and death where certain cells find new life as multicellular organisms.

Fred Hutch researchers have created a gene-expression map of glial cells of the tiny worm, C. elegans, adding the missing ...

This most fundamental question was famously posited by none other than Nobel laureate physicist Enrico Fermi (1901–1954).

By looking at the microbial communities that live on corals, our research uncovered a crucial role that fishes play in protecting coral reefs. We also discovered that these fishes together with clean ...

A better understanding of human smell is emerging as scientists interrogate its fundamental elements: the odor molecules that ...

Single-celled organisms called archaea aren't generally thought to cause human disease, but one species has been implicated in colorectal cancer ...
