(Related personal anecdote and why I recommend them so highly: I'd been listening to them for awhile, then a research paper came out showing a possible link between Chronic Fatigue Syndrome and XMRV in mice. People online had taken the paper and went crazy with it and some people were finding sources for murine (mouse) cancer drugs and dosing themselves with it in hopes of curing their CFS. They went through the paper and recognized the researcher and lab who wrote it. And noted that the lab had previously published XMRV research. XMRV is apparently remarkably difficult to eliminate contamination from. Basically if a lab has ever worked with it, you have to burn down the lab and build anew if you want to be sure it isn't around. So they advocated skepticism and said wait for independent verification before getting too worked up. A couple months later, the original paper was retracted as the researchers announced no other lab could reproduce their findings and it was down to XMRV contamination of their samples. That is the kind of thing you only get when you're listening to bona fide experts in their field and it blew my mind.
