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 ...

Archaea—one of the three primary domains of life alongside bacteria and eukaryotes—are often overlooked and sometimes mistaken for bacteria due to their single-celled nature and lack of a nucleus. Yet ...

A study presents a striking example of cooperative organization among cells as a potential force in the evolution of multicellular life. The study is based on the fluid dynamics of cooperative feeding ...

The diversity of unicellular eukaryotes covered in the study, with their nucleus (blue) and microtubule cytoskeleton (magenta) stained. These organisms are so distantly related to each other as they ...

Much more difficult is learning to connect different types of stimuli or events, and predicting that one is linked to another. Such associative learning was most famously demonstrated when Ivan Pavlov ...

Over 3,000 generations of laboratory evolution, Georgia Tech researchers watched as their model organism, “snowflake yeast,” began to adapt as multicellular individuals. [email protected] ...

Why have bacteria never evolved complex multicellularity? A new hypothesis suggests that it could come down to how prokaryotic genomes respond to a small population size. Every organism visible to the ...

A research group led by Associate Professor Tetsuya Muramoto from the Faculty of Science, Toho University, has established a CRISPR genome editing technique that enables comparative analysis of the ...

“Animals are regarded as this very special branch, as in, there had to be so many innovations to be an animal,” David Booth, a biologist at the University of California, Berkeley, who wasn’t involved ...
