Scientists may have uncovered a new way for cells to regulate protein expression. In the December 16 Neuron, researchers led by Mary Hynes at Rockefeller University, New York, reported that in mouse ...

In what appears to be an unexpected challenge to a long-accepted fact of biology, researchers say they have found that ribosomes -- the molecular machines in all cells that build proteins -- can ...

Ribosomes, normally obedient to stop and start signals on messenger RNA, occasionally “go rogue.” They take it upon themselves to build proteins beyond the usual coding sequence, overrunning a portion ...
