A cell's life is a noisy affair. These building blocks of life are constantly changing. They can spontaneously express different proteins and genes, change shape and size, die or resist dying, or become damaged and cancerous. ...

A team of researchers with the University of California has found a way to show how historical contingencies constrained the evolution of a gene regulatory network. In their paper published in the journal Nature, the team ...
An artificial intelligence system has for the first time reverse-engineered the regeneration mechanism of planaria—the small worms whose extraordinary power to regrow body parts has made them a research model in human regenerative ...

If you never understood what "ontogeny recapitulates phylogeny" meant in high school, don't worry: biologists no longer think that an animal's "ontogeny", that is, its embryonic development, replays its entire evolutionary ...
