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.

BPA induces sterility in roundworms
Bisphenol A does a real number on the genes responsible for successful reproduction in a 1-millimeter-long soil-dwelling roundworm. And that suggests BPA might pose similar risks to people because geneticists are finding that this tiny critter can be a remarkably useful “lab rat” — predicting impacts in mammals, including us.

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. In a few grocery stores, cashiers have already begun donning gloves to avoid handling thermal receipt paper whose BPA-based surface coating may rub off on the fingers. But how’s a family to avoid exposure to this contaminant when it taints the food supply?

Skin is no barrier to BPA, study shows
The new finding suggests handling store receipts could be a significant source of internal exposure to the hormone-mimicking chemical.
