How did life make the leap from single cells to coordinated, multicellular organisms? And how do genetically identical cells ...

The world would look very different without multicellular organisms—take away the plants, animals, fungi, and seaweed, and Earth starts to look like a wetter, greener version of Mars. But precisely ...

In order for vertebrate embryos to develop their body axes, they require what is known as an embryonic signaling center. This ...

All the living things that we can see evolved from those that we can’t. Every human, bird, tree, and flower can trace its ancestry across a few billion years back to microscopic, single-celled ...

A recent study by Ruibao Li and Jennah Dharamshi published in Nature may help us understand the beginnings of animal ...

Researchers have discovered the first in-situ evidence of chlorophyll remnants in a billion-year-old multicellular algal microfossil preserved in shales from the Congo Basin. This discovery has made ...

A team of scientists, led by the University of Sheffield in the UK and Boston College in the U.S., has found a microfossil in the Scottish Highlands which contains two distinct cell types and could be ...

Cells can compensate a disruptive change in one ion channel by compensatory changes in other channels. We have simulated the adaptation of a multicellular aggregate of non-excitable cells to the ...

We are providing an unedited version of this manuscript to give early access to its findings. Before final publication, the manuscript will undergo further editing. Please note there may be errors ...

Marine bacteria normally seen as single cells join together as a “microscopic snow globe” to consume bulky floating carbohydrates. Close your eyes and imagine bacteria. Perhaps you’re picturing our ...

In the multicellular soil bacterium Streptomyces coelicolor, some cells start producing lots of antibiotics after mutations delete big chunks of their genomes. Now a computer model has helped to ...

Over 3,000 generations of laboratory evolution, researchers watched as their model organism, 'snowflake yeast,' began to adapt as multicellular individuals. In new research, the team shows how ...
