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 /> ...

Ribosomes, the cell's protein-making factories, consume large amounts of energy as they build the proteins that keep cells alive and functioning. When cells experience stress—such as lack of nutrients ...

Half a billion years ago, the first true eye emerged in Earth’s oceans. Fossils now reveal what that ancient crystal vision ...

Mitochondria, also known as the powerhouses of the cell, are essential for cell survival, repair, and adaptation. Not only do they generate most of ...

Northwestern researchers have shown that when it comes to cancer vaccines, arrangement can be just as important as ingredients. By repositioning a small fragment of an HPV protein on a DNA-based ...

Building functional human muscle in the laboratory has long been a goal of regenerative medicine, but one stubborn obstacle remains: real muscle is not just a mass of cells. Its strength and function ...

Other cells, such as glial cells, support the function of neurons. Neuroscience has often painted glial cells as the glue that holds neurons together, but glial cells can also be helpful in promoting ...

Advances in organ and computer models are raising the prospect that some animal experiments could be eliminated. But there ...
