Feds propose banning giant snakes

Today, the U.S. Fish & Wildlife Service announced plans to ban the importation and interstate transport of nine species of giant snakes. It’s a good idea, but a little like closing the barn door after the horse — or in this case, the pythons and anacondas — got loose.

BPA is regulated . . . sort of

Food and Drug Administration officials “say they are powerless to regulate BPA” because of a quirk in their rules, according to a story that ran Sunday in the Milwaukee Journal Sentinel. It comes from a reporter who has made an award-winning habit of documenting the politics that have helped make the hormone-mimicking bisphenol-A a chemical of choice for many manufacturers.

IPCC relied on unvetted Himalaya melt figure

British newspapers have uncovered what appears to be an embarrassing fact-checking omission by the Intergovernmental Panel on Climate Change, or IPCC. It regards the degree of glacial melting in the Himalayas — information that said parts of the area could be icefree a quarter century from now.

BPA and babies: Feds acknowledge concerns

Federal health and research officials outlined new guidance today for parents on the use of plastics made from bisphenol-A, a hard, clear plastic. Their bottom line: Minimize BPA-based products that could make contact with foods or drinks that infants or toddlers might consume — especially hot foods and drinks. But the Food and Drug Administration stopped short of recommending that parents pitch baby bottles and sippy cups made from BPA. Nor did it call for parents to avoid processed infant formulas and baby foods — some of which it acknowledges are contaminated with traces of BPA.
