I'm seeing a lot of people support or dismiss these findings for bad reasons. Hilariously, some people are dismissing papers because "the authors have a history of publishing papers about this stuff". In other words, papers on X are wrong because they are about X. This is reasoning on the level of "God exists because the Bible says He does, and the Bible is true because God wrote it". It's just going in a loop and spitting back your original preconceptions, without actually processing the evidence. You can't actually learn anything that way!

I scanned through some of the mouse studies, but they all had the same problem for me: to see effects, they blasted the mice with huge powers, on the order of 1 W/kg absorbed. For reference, the human body itself, through all its metabolic activity, barely generates that much. If you were absorbing anything near 1 W/kg of power at any frequency, you would start overheating, as if you'd just stepped out into the midday sun. Increase that by a few times, and you would probably shortly die, by literally being cooked. So I think most of those studies can be safely discarded. Anything is bad for you at those crazy intensities, which are far higher than what you get from a cell phone.

Of course, this leaves a lot of other studies that may or may not be more solid -- but without more time I can't draw any solid opinions.
