Update on Rossi: independent test finds his device produces excess heat with energy density at least ten times higher than conventional energy sources.
Story here, critical response here, more positive responses here and here
Okay, so having read through the paper and looked at reactions on the internet, my opinion is that the work looks solid, with no obvious flaws in their methodology. It seems likely that the device was outputting the amount of heat that they measured (or more). However, some critics have pointed out a possible loophole in the measurement of the input power. The claim (if I understand it correctly) is that Rossi could have been feeding in extra current at a low frequency (DC) that apparently could have been missed by the power meter the scientists used to measure the input power. I don’t know enough about the instrument or these kinds of experiments to comment on how likely this is. Another claim being made is that he could have been using radio waves to wirelessly transfer energy to inductive coils within the device, supplying the measured excess heat. Again, not my area of expertise, but it sounds plausible. Mind you there’s no evidence that he did do either of these things, but given his history it’s certainly a possibility.
Interesting stuff. I’ll be keeping an eye out for further news.

Edit: Oh, right, and paper here
