It iss essential for cells to quickly ascertain whether it's possible to repair mistakes or to self-destruct for the good of the organism. That's because cells with a damaged genome often begin to flout the standard rules of growth and become cancerous. Now, researchers have discovered a new player…

To fill in the blanks on mitochondria, researchers deleted 174 genes, one by one, in yeast. They then subjected the yeast to high-intensity mass spectrometry to measure unprecedented detail on thousands of metabolic products, including proteins, intermediate chemicals called metabolites, and lipids.
