As the volume increases, the surface area does not increase at the same rate. When the surface area to volume ratio is large, there is a lot of surface area for diffusion and not much volume to travel ...

Induction of Multicellularity: When mechanically compressed, the salt-loving archaeon Haloferax volcanii can shift from being single-celled to forming tissue-like clusters, displaying new mechanical ...

MicroRNAs (miRNAs) — a class of small RNAs with a role in the regulation of gene expression — had until now been found only in multicellular organisms. Now, Wang, Qi and colleagues provide the first ...

The diversity of unicellular eukaryotes covered in the study, with their nucleus (blue) and microtubule cytoskeleton (magenta) stained. These organisms are so ...

Scientists have discovered the fossil of what may be the earliest multicellular animal ever found. Dating back a billion years, the microscopic fossil contains two distinct cell types, potentially ...

The transition from single-celled organisms to multicellular ones was a major step in the evolution of complex life forms. Multicellular organisms arose hundreds of millions of years ago, but the ...

The snowflake yeast had been shipped from William Ratcliff’s laboratory at the Georgia Institute of Technology in the U.S. Regular yeast — the same organism that makes bread fluffy — grows as a single ...

Chromosphaera perkinsii is a single-celled species discovered in 2017 in marine sediments around Hawaii. The first signs of its presence on Earth have been dated at over a billion years, well before ...

Images of the multicellular development of the ichthyosporean Chromosphaera perkinsii, a close cousin of animals. In red, the membranes and in blue the nuclei with their DNA. The image was obtained ...

Researchers have discovered that environments favoring clumpy growth are all that’s needed to quickly transform single-celled yeast into complex multicellular organisms. To human eyes, the dominant ...
