When cells experience a high level of stress—for example, when they are exposed to too much UV light—ribosomes inside the cell collide and get into traffic jams. Now, Johns Hopkins scientists have found a protein that ...

Mitochondria cannot autonomously cope with stress and must instead call on the cell for help. Molecular geneticists at LMU have identified the long-sought signaling pathway which enables the organelles to do so.
