Review of some recent work on acceleration radiation

Some developments in quantum field theory in accelerated frames that may not have got the attention they deserve are reviewed here. They concern (1) elementary particles as radiating accelerated detectors; (2) sound calculations of mirror and black-hole radiation; (3) vacuum energy in the presence of accelerated boundaries; (4) exhaustive study of all accelerated stationary frames in flat space, resolving the issue of the effects of rotation. Some related outstanding questions are mentioned.
