As organisms develop from embryos, groups of cells migrate and reshape themselves to form all manner of complex tissues.

In research that could shed light on the growth and formation of complex tissue architectures, Brown University engineers ...

In fact, why and how multicellular life evolved has long puzzled biologists. The first known instance of multicellularity was about 2.5 billion years ago, when marine cells (cyanobacteria) hooked up ...

Scientists at Nagoya University in Japan have identified the genes that allow an organism to switch between living as single cells and forming multicellular structures. This ability to alternate ...

The mystery of how multicellular life evolved has long baffled scientists, who've spent years trying to understand how solitary single-celled organisms began living in unison and triggered the ...

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 ...

A growing body of work suggests that cell metabolism — the chemical reactions that provide energy and building materials — plays a vital, overlooked role in the first steps of life. Each of us starts ...
