Nuclear magnetic resonance is vital for analysis and diagnostics but suffers from insensitivity as only a small fraction of all NMR-active nuclei are spin-polarized and contribute to the signal. Here Hövener et al. describe an effect that replenishes nuclear spin polarization continuously for a considerably enhanced performance at low field.
