Fitting a right hand in a left-handed mitten

Many biomolecules come in two versions that are each other's mirror image, like a left and a right hand. Cells generally use the left-hand version of amino acids to produce proteins, and uptake mechanisms were thought to ...

The clouds of spaghetti that keep DNA data safe

Cells can avoid "data breaches" when letting signaling proteins into their nuclei thanks to a quirky biophysical mechanism involving a blur of spaghetti-like proteins, researchers from the Rockefeller University and the Albert ...

Researchers one step closer to cocaine antidote

Researchers at the University of Copenhagen have gained new insight into the mechanism behind a protein dopamine transporter that could help in the development of future medical treatment against cocaine addiction.

Revealing the inner workings of a molecular motor

In research published in the Journal of Cell Biology, scientists from the RIKEN Brain Science Institute in Japan have made important steps toward understanding how dynein—a "molecular motor"—walks along tube-like structures ...
