We report the cooling of an atomic ensemble with light, where each atom scatters only a single photon
on average. This is a general method that does not require a cycling transition and can be applied to atoms
or molecules that are magnetically trapped. We discuss the application of this new approach to the cooling
of hydrogenic atoms for the purpose of precision spectroscopy and fundamental tests.
