Metal water bottles may leach BPA
Consumers who switched from polycarbonate-plastic water bottles to metal ones in hopes of avoiding the risk that bisphenol A will leach into their beverages aren’t necessarily any better off, a new study finds. Some metal water bottles leach even more BPA — an estrogen-mimicking pollutant — than do ones made from the now-pariah plastic.

I only wish I knew then what I do now.

AAAS board defends climate scientists
“AAAS vigorously opposes attacks on researchers that question their personal and professional integrity or threaten their safety based on displeasure with their scientific conclusions.” This declaration was contained in a 400-word denunciation of attacks on climate scientists and the politicization of climate science that was issued June 29 by the organization's board of directors.
