    Science & the Public: More evidence that BPA laces store receipts
    People interested in limiting exposure to bisphenol A — a hormone-mimicking environmental contaminant — might want to consider wearing gloves the next time a store clerk hands over a cash-register receipt. A July 27 report by a public-interest research group has now confirmed many of these receipts have a BPA-rich powdery residue on their surface.

  • Science & the Public: Good vibrations: A greener way to pasteurize milk
    Many people like the taste of raw – as in unpasteurized – milk. The problem, of course, is that germs may infect raw milk, so food safety regulations require that commercial producers heat-treat their milk. But food scientists at Louisiana State University think they’ve stumbled onto a tastier way to sterilize milk. They bombard it with sound waves.
  • Science & the Public: Nano-scale additives fight food pathogens
    Nano products are all the rage, even in food science. Here at the Institute of Food Technologists’ annual meeting, on July 18, scientists described dramatic success in fighting food-poisoning bacteria by doctoring foods or their packaging with microbe-killing nanoparticles – sometimes along with natural anti-bacterial agents.

Science & the Public: Breast screening tool finds many missed cancers
A relatively new imaging option outperforms all comers in scouting for hidden breast tumors. Indeed, argues radiologist Rachel Brem, her team’s new data indicate that that “almost 10 percent of women with breast cancer have another [tumor] that we wouldn’t know about without this technology.”
Science & the Public: Ivy nanoparticles promise sunblocks and other green products
I’ve developed a love-hate relationship with English ivy that’s been devolving towards hate-hate. But a new paper may temper my antipathy. Apparently this backyard bully also offers a kinder, gentler alternative to the potentially toxic metal-based nanoparticles used in today’s sunscreens.

Science & the Public: BP oil isn’t the only source of gulf's deep roaming plumes
During a June 8 briefing for reporters, a NOAA science officer described deep strata of water tainted with oil identified during a recent cruise in the Gulf of Mexico. The presumption was that anything they found would be plumes of oil spewed by the jet of hydrocarbons emanating from the BP well head. But the chemical fingerprinting of diffuse undersea clouds of oil at one sampling site was “not consistent with BP oil,” he pointed out.
