microscope, because tumour tissue looks the same as fat. Now Samuel Singer and
his colleagues at Brigham and Women’s Hospital in Boston, Massachusetts, have
discovered a better way to diagnose a type of tumour which accounts for a third

based on nuclear magnetic resonance. This measures the relative amounts of two
telltale metabolites. The ratio of these metabolites determines whether the
cells are…
