Scientists often act as detectives, piecing together clues that alone may seem meaningless but together crack the case. Professor Reuben Shaw has spent nearly two decades piecing together such clues to understand the cellular response to metabolic stress, which occurs when cellular energy levels dip. Whether energy levels fall because the cell’s powerhouses (mitochondria) are failing or due to a lack of necessary energy-making supplies, the response is the same: get rid of the damaged mitochondria and create new ones.
