We'll discuss a new magnetic trap under development in Rio for atomic
and molecular species with magnetic moment. The trap is based on the
sublimation of a neon isolation matrix at cryogenic temperatures. We
also describe the lasers being built for all these species'
high-resolution spectroscopy. The motivation of the work with hydrogen
and positronium is for basic tests of physics, such as the CPT
symmetry and the Weak Equivalence Principle. We describe the
developments in Geneva, by the ALPHA collaboration, towards trapping
of antihydrogen. As an appendix, we mention the potential use of cold
OH for quantum computation.
