Heavy water makes biological clocks tick more slowly

Scientists have succeeded in reversibly slowing down cellular processes. A team of biophysicists were able to show in experiments that cells can be transferred into slow motion without changing the temperature. From a physical point of view, such possibilities have so far only been available in the context of the theory of relativity.
