Pulsars constitute some of the most mysterious particle accelerators in the Universe. Due to their extreme rotational energies and strong magnetic fields, they can accelerate cosmic rays to extremely high energies. In accelerating cosmic rays, pulsars co-produce copious amounts of gamma rays which provide a crucial tool to unravel the physics governing them.  In this talk, I will discuss recent theoretical and experimental developments in pulsar physics, then explain their potential to explain several puzzling excesses in the data historically attributed to exotic signals of new physics, e.g., the Fermi GeV excess, the Sagittarius dwarf spheroidal galaxy excess, the Andromeda excess, the 511 keV positron line excess, and others.
