A new study led by the Yunnan Observatories of the Chinese Academy of Sciences has detected quasi-periodic oscillation (QPO) signals in an unusual gamma-ray burst (GRB) event. The findings are ...

Many physiological behaviours of cells are repeated periodically in time, such as hormone secretion, second messenger signalling, cell-division cycles and circadian rhythms. Oscillatory behaviour is a ...

Ocean-atmosphere oscillations are naturally occurring cycles affecting sea surface temperature and precipitation. They are among the key reasons why some years are dry and plagued by drought while ...
