Newfound water risk: Lead-leaching valves

BPA: EPA hasn’t identified a safer alternative for thermal paper
Some researchers and public interest groups have been arguing that BPAfree thermal receipts paper is a preferable alternative, at least from a health perspective. But is it really? That’s what Environmental Protection Agency scientists want to know. And to date, they maintain, the jury’s still out.

Election projections for science investments
The November 2, mid-term election results are in (mostly) and pundits are billing it as a historic turnabout. With a divided Congress, passing legislation — never an easy task — risks becoming harder still. And with fiscal austerity having been a leading campaign issue for the newbies, R&D is unlikely to see a major boost in federal funding during the next two years.

Plenty of foods harbor BPA, study finds
Some communities have banned the sale of plastic baby bottles and sippy cups that are manufactured using bisphenol A, a hormone-mimicking chemical.

But how’s a family to avoid exposure to this contaminant when it taints the food supply?

Contemplating an Arctic oil spill
The waters off northern Alaska may be “the largest oil province in the United States” after the Gulf, notes Edward Itta, a native of Barrow, Alaska. He is also mayor of the North Slope Borough, an 88,000-square-mile jurisdiction that runs across the upper part of the state. And in a September 27 videoconference with the National Commission on the BP Deepwater Horizon Oil Spill and Offshore Drilling, he tried to impress upon the commissioners just how remote his neck of the tundra is.
