PASTA helps marathon runners keep the pace – and maybe some spinning stars too. Rapidly rotating neutron stars called pulsars should slow down over time as they radiate energy. But lone pulsars appear to settle at a rate of about 12 seconds per spin. José Pons at the University of Alicante in Spain and colleagues ran simulations of pulsars with different crust configurations. Those with lumpy crusts slowed to between 10 and 20 seconds and stayed steady at that rate (Nature Physics, DOI:
