Time for New Cookware
We all kinda knew it was true, but were hoping that the evidence wouldn't surface: Teflon seems to be carcinogenic. Specifically, an independent panel has advised the EPA to upgrade a chemical used in producing Teflon - PFOA - to a "likely carcinogen." Needless to say, the companies which produce PFOA "disagree" with the recommendation. There is no real suggestion that they think the panel's findings are inaccurate, just that they think they don't matter. Now, what am I going to do with all of my nonstick cookware??
Unrelatedly, another study may have found an answer to the puzzle of why prions have survived evolution. In mice engineered not to produce prions, their marrow (stem) cells slowly deteriorated and stopped regenerating themselves. So, it seems that prions play a critical role in stem cell activity. Weird.
