Firefighters’ Blood Holds Chemicals Related to Potentially Toxic Compound. Scientific Ame13698187_s from 123rfrican

Perfluorinated compounds, such as perfluorooctane sulfonate (PFOS), help firefighting foams rapidly flow over flaming liquids such as gasoline and jet fuel, cooling and quenching fires. But despite environmental scientists’ concerns about these possibly toxic compounds accumulating in wildlife and lurking in firefighters’ blood, researchers don’t know the identity of many of the chemicals in the mixtures on the market. For the first time, a new study borrows a medical research tool to pinpoint fluorochemicals in the blood of firefighters, identifying novel compounds that have never before been publicly reported (Environ. Sci. Technol. 2015, DOI: 10.1021/es503653n).  Read more…

Sometimes light is not so fast. Science News for Students

The speed of light is often called a “constant.” New experiments show that may not be true, even within a vacuum. Sometimes, light slows a bit. The new research is “very impressive work,” Robert Boyd told Science News. An optical physicist at the University of Rochester in New York, he did not work on the study. He says of the new finding: “It’s the sort of thing that’s so obvious, you wonder why you didn’t think of it first.” Read more…

Big Gap between What Scientists Say and Americans Think about Climate Change. Scientific American

There is good and bad news for climate scientists. The good news: Most Americans (79 percent) say that science and scientists are invaluable.  The bad news: On controversial topics such as climate change, a significant number of Americans do not use science to inform their views. Instead, they use political orientation and ideology, which are reflected in their level of education, to decide whether humans are driving planetary warming. Read more…
