    BPA and babies: Feds acknowledge concerns

    Federal health and research officials outlined new guidance today for parents on the use of hard, clear plastics made from bisphenol-A, a hormonelike chemical. 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...

    BPA: On the way out? Sort of

    I ran across a Chicago Trib story noting that the city council voted yesterday to make the Windy City America’s first community to ban sales of polycarbonate-plastic baby bottles and “sippy” cups. A lofty claim, but every town and hamlet in Minnesota is actually slated to beat Chicago by 30 days.

    Indeed, five days before Chicago did, Minnesota declared it was outlawing baby beverage-...

    How Plastic We've Become

    In the 1967 film classic The Graduate, a businessman corners Benjamin Braddock at a cocktail party and gives him a bit of career advice. "Just one word…plastics."

    Although Benjamin didn't heed that recommendation, plenty of other young graduates did. Today, the planet is awash in products spawned by the plastics industry. Residues of plastics have become ubiquitous in the environment—and...

    Troubling Meaty 'Estrogen'

    Women take note. Researchers find that a chemical that forms in overcooked meat, especially charred portions, is a potent mimic of estrogen, the primary female sex hormone. That's anything but appetizing, since studies have linked a higher lifetime cumulative exposure to estrogen in women with an elevated risk of breast cancer.

    Indeed, the new finding offers a "biologically...

    Tea compound aids dying brain cells

    From Washington, D.C., at the Fourth International Scientific Symposium on Tea and Human Health

    A constituent of green tea can revive moribund brain cells, Israeli researchers report. The team experimented with animal neurons that had been chemically poisoned to model the death of dopamine-producing cells in Parkinson's disease.

    In a test-tube study, low doses of epigallocatechin...

    Sour Genes, Yes—Salty Genes, No

    Some people abhor broccoli, complaining about its intensely bitter taste. Others (myself included) find broccoli's flavor interesting and pleasing—decidedly, not bitter. What leads to our differing culinary opinions is the possession of, or lack of, (in my case, evidently) genes conferring a super sensitivity to bitter taste. Science has recognized such genetic differences for at least a...

    Plastics ingredient disrupts fetal-egg development

    A common estrogen-mimicking chemical can damage eggs while an animal is still in the womb, researchers report.

    Bisphenol A is found in polycarbonate plastics—those used to make baby bottles and hard-shell water bottles—and in the lining of food cans. The chemical also turns up in human tissues at concentrations of several parts per billion.

    Earlier research had linked bisphenol A...

    Bad-News Beauties

    With striking red, black, and white stripes decorating its body, fins, and some dozen spines along its head, back, and sides, the red lionfish is at once beautiful and frightening. The football-shaped fish can grow up to 18 inches long and is poisonous to the touch. At smaller sizes, this subtropical fish from Asia is extremely popular for hobbyists with saltwater aquariums, but the red...

    Plastics agent worsens skin allergies

    Low doses of one of the most commonly used softeners in plastics can aggravate dust-mite allergy, researchers report.

    The plasticizer di(2-ethylhexyl) phthalate (DEHP) is ubiquitous in air, water, and most people's bodies. It's in plastics used for toys, food packaging, medical products, and housewares.

    A few earlier studies had correlated allergy severity with exposure to DEHP in...

    Fish as Farmers: Reef residents tend an algal crop

    A damselfish cultivates underwater gardens of an algal species that researchers haven't found growing on its own.

    The special alga could be the fishy version of people's domesticated crops, says Hiroki Hata of Kyoto University in Japan. Growth tests of the alga, surveys of its distribution, and genetic analyses support that idea, he and Makoto Kato say in an upcoming Biology...
