Multicellular Organism

Life, uh, finds a way.

Could tiny swimming microbes help us unlock the mysteries of extraterrestrial life?

Scientists at the University of Bergen have uncovered a remarkable diversity of behaviors within the rosette-shaped colonies of Salpingoeca rosetta, a rare species of choanoflagellate -- the closest relatives of animals.

Does carcinization mean humans will one day grow pincers? Not exactly, but the concept is still fascinating

The Nobel Assembly said that the discovery is "fundamentally important."

US scientists Victor Ambros and Gary Ruvkun helped explain how genes work inside the human body.

Biobots are tiny, multicellular robots powered by living cells to perform tasks, and they're a third state between life and death. The post Biobots are a 3rd state between life and death first appeared on EarthSky.

The sun is midway through its life of fusion. It's about 5 billion years old, and though its life is far from over, it will undergo some pronounced changes as it ages. Over the next billion years, the sun will continue to brighten.

Given the right conditions, certain types of cells are able to self-assemble into new lifeforms after the organism they were once part of has died.

The research focused on a previously unknown peak in the underwater Nazca Ridge.

Using evolution as a guiding principle, researchers have successfully engineered bacteria-yeast hybrids to perform photosynthetic carbon assimilation, generate cellular energy and support yeast growth without traditional carbon feedstocks like glucose or glycerol. By engineering photosynthetic cyanobacteria to live symbiotically inside yeast cells, the bacteria-yeast hybrids can produce important hydrocarbons,…

In just 48 hours, salps can reach maturity, making them the fastest-growing multicellular animals on Earth, with a significant impact on ocean health.

Colonies of these choanoflagellates — members of a group considered to be the closest living relatives of all animals — have their own unique microbiomes.

When you become infected with a virus, some of the first weapons your body deploys to fight it are those passed down to us from our microbial ancestors billions of years ago. According to new research from The University of Texas at Austin, two key elements of our innate immune system came from a group of microbes called Asgard archaea.

Complex life likely arose after a pretty frosty time.

All life on Earth can be traced back to a Last Universal Common Ancestor, or LUCA—and it likely lived on Earth only 400 million years after its formation.

Scientists led by MIT's Michael Yaffe unveiled a comprehensive atlas of human tyrosine kinases. Using the atlas and mass spectrometry data, researchers can identify kinases involved in cell signaling, such as during inflammation or cancer progression.

Can I get a "brain worm" from eating undercooked meat? There's little I find more terrifying than the idea of something living and crawling around inside

It's so much older than we thought.

Modern biology textbooks assert that only bacteria can take nitrogen from the atmosphere and convert it into a form that is usable for life. Plants that fix nitrogen, such as legumes, do so by harboring symbiotic bacteria in root nodules. But a recent discovery upends that rule.
