Holly Krieger has won a Whitehead Prize for work that combines number theory and dynamical systems.

Maria Bruna has won a Whitehead Prize for finding a systematic way of simplifying complex systems.

How do green algae manage a perfect breaststroke even though they haven't got a brain? Enter the maths of synchronisation.

We all now know about R, but sometimes it can be good to consider another number: the growth rate of an epidemic.
