How did vertebrates first evolve jaws?

Five-hundred million years ago, it was relatively safe to go back in the water. That's because creatures of the deep had not yet evolved jaws. In a new pair of studies in eLife and Development, scientists reveal clues about ...

The new heroics of RNA in cell differentiation

Scientists are increasingly learning of new reasons to appreciate RNA, and the glycolytic enzyme ENO1 seems to have provided yet another in new research from EMBL this week, as published in Molecular Cell.

How embryo cells gain independence

It happens in the first hours after fertilization: The cells of the early embryo begin to independently produce proteins, the building blocks for cells and organs. Their own, uniquely composed genetic material serves as the ...

Research illuminates embryonic stem cell fate

USC postdoctoral researcher Xi Chen knows that you have to break a few eggs in order to grow chicken stem cells. His work on maintaining embryonic stem cells (ESC) from chicken eggs provides insight into stem cell pluripotency ...

High-speed model for the fight against SARS-CoV2

To contain the SARS-CoV2 coronavirus and slow the spread of infections and the rising death toll, researchers and health professionals around the world are rapidly developing vaccines and medical drugs. But before these can ...

Unraveling a mystery surrounding embryonic cells

Last year, researchers at the University of California, Riverside, identified the early origins of neural crest cells—embryonic cells in vertebrates that travel throughout the body and generate many cell types—in chick ...
