Under stress, animal cells pair inactive ribosomes into RNA-linked disomes. A ribosomal RNA “kissing loop” joins them, protecting ribosomes and reducing protein synthesis to conserve energy.<br /> ...

LaBonne is president of the Society for Developmental Biology and the Erastus Otis Haven professor of molecular biosciences at Northwestern University. Imagine a world without lifesaving medicines, ...

Ribosomes, the cell's protein-making factories, consume large amounts of energy as they build the proteins that keep cells ...

Quick Take Eastern Emerald Elysia rely on the algae Vaucheria litorea to complete its development. The sea slug retains ...

A new study shows, for the first time, that cow cells can naturally become immortal—continuing to divide indefinitely without genetic modification or any abnormal transformation. This overturns ...

Using DNA and proteins, scientists have created new synthetic cells that act like living cells. Blurring the line between artificial and living materials, these cells can be reprogrammed to perform ...

Critical proteins involved in animal stem cell regulation are much older than previously thought, predating the origin of animals that likely evolved more than 700 million years ago. This is the ...

Cell biology is a branch of biological sciences that investigates the structure, function, dynamics, and regulation of cells as the fundamental units of life. It encompasses the study of cellular ...

For much of the 20th century it was thought that the adult brain was incapable of regeneration. This view has since shifted dramatically and neurogenesis – the birth of new neurons – is now a widely ...
