Over the last decades it has become routine to form beams of positrons and antiprotons to produce trapped samples of both species for a variety of purposes. Positrons can captured efficiently and in such quantities to form dense, single component plasmas useful for antihydrogen formation. The latter was made possible by developing techniques for dynamically capturing and then cooling antiprotons ejected from the Antiproton Decelerator at CERN .

We will review recent advances which have led to the demonstration of the capture of antihydrogen in a magnetic minimum neutral atom trap, and the first physics experiments, including the observation of a resonant quantum transition in the anti-atom.

We will discuss the physics motivations for undertaking these difficult experiments and describe near-future initiatives.
