What this press release doesn't say is that some of those other groups
have been using telescopes that were built specifically to study the
Sunyaev-Zel'dovich (SZ) effect. It's been a while since I read the
paper, but my recollection is that this group did not explain why
other groups would have obtained discrepant results.
The Lieu et al. effect is interesting, but I think it is a bit early
to be writing an obituary for the cosmic microwave background.
