Why did researchers take a knife to a cute little plastic gingerbread man? To make him give up the source of his toxic fumes. Or so explained Bill Doucette, this morning, in a particularly entertaining session at the Society for Toxicology and Environmental Chemistry’s annual meeting. But the underlying message that this Utah State University scientist brought home to his audience was anything but funny. He graphically illustrated that hidden dangers may lurk in surprising places.Published: Saturday, November 21st, 2009Found in: Chemistry, Environment, Molecules and Science & Society

No one would choose to eat polychlorinated biphenyls, or PCBs — yet we unwittingly do. And a new study finds that the cost of their pervasive contamination of our food supply can be elevated blood pressure, a major risk factor for heart disease.Published: Tuesday, November 17th, 2009Found in: Biomedicine, Environment and Science & Society

Home / Blogs / Science & the Public / Science & the Public : Record chills are falling, but in number onlyWeather-monitoring stations in the Lower 48 have been logging record daily highs in temperature at twice the pace of record lows. Yet more evidence of climate warming. Many people have pointed to colder than normal winters — or summers — as evidence that global warming is a myth. Climatologists have countered that weather, the meteorological features that we experience at any given hour or day, may show anomalies even as Earth’s overall climate warms. So weather can locally mask the planet’s overall slowly rising fever. Except that any such mask appears to be disappearing throughout most of the United States, according to a new study.Published: Thursday, November 12th, 2009Found in: Climate Change and Science & Society

Some readers may be unaware of our sister publication, Science News for Kids, a weekly online magazine for middle-school readers. This morning, we learned that one of the site’s feature stories — Where Rivers Run Uphill — won this year’s top science journalism award for reporting news for children.Published: Tuesday, November 10th, 2009Found in: Earth Science, Environment, Science & Society and Science News For Kids -
Home / Blogs / Science & the Public / Science & the Public : Guarded optimism on Copenhagen climate talksNegotiators representing 181 nations completed their final prep work in Barcelona, Spain, last Friday, on a new climate treaty — one that they hope to build a month from now at a major conference in Copenhagen, Denmark. But at least one scientist worries that what comes out of the Copenhagen deliberations may not have sufficient coordination and strength to meet the challenges that Earth’s climate has begun throwing at us.Published: Monday, November 9th, 2009Found in: Climate Change, Environment and Science & Society

Under California’s Proposition 65 law, products containing chemicals that may cause cancer, birth defects or reproductive toxicity must carry a warning label at their point of sale. Among such products: pricy balsamic and red-wine vinegars that contain lead. At least some California groceries apparently have taken a conservative approach and post labels suggesting all such vinegars are dangerously tainted. Although they aren't.Published: Monday, November 9th, 2009Found in: Agriculture, Food Science, Nutrition and Science & Society -

Home / Blogs / Science & the Public / Science & the Public : Kyoto climate treaty's greenhouse 'success'There are 33 days until the opening of formal negotiations in Copenhagen on the next global climate-protection treaty. The hoped-for accord would take up where the current treaty leaves off. But to get some perspective on just where that is, a new United Nations report describes for negotiators and the public just how much the Kyoto Protocol has achieved. And real strides have been made in slowing the growth of greenhouse-gas emissions, thanks to many European nations (albeit with little help from North American ones or Japan).Published: Tuesday, November 3rd, 2009Found in: Climate Change and Science & Society -
