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

PROVIDENCE, R.I. [Brown University] — As organisms develop from embryos, groups of cells migrate and reshape themselves to form all manner of complex tissues. There are no anatomical molds shaped like ...

Life’s leap from single-celled to multicellular organisms marks a pivotal moment in evolutionary history. This transformation laid the foundation for the complex life forms we see today. By studying ...

Life emerged on Earth some 3.8 billion years ago. The “primordial soup theory” proposes that chemicals floating in pools of water, in the presence of sunlight and electrical discharge, spontaneously ...

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 ...

Researchers have discovered a mechanism steering the evolution of multicellular life. They identified how altered protein folding drives multicellular evolution. Researchers have discovered a ...

The design of synthetic developmental programs for multicellular mammalian systems is a cornerstone of synthetic biology. The programs hinge on the construction of gene regulatory circuits that ...

Bacterial superorganisms must evolve defenses to fight off infections, and microbiologists found that they use a weapons cache coincidentally similar to that of the human immune system. B cells churn ...

Blood cells carry a deep evolutionary history. A new analysis suggests their earliest ancestors were macrophage-like cells ...
