ChemistryDecon Green can clean up the most toxic messes, developers claim
A new decontaminant could be a more benign alternative for cleaning up after chemical and biological accidents.
-
Materials ScienceInfection, kill thyself
Scientists devise wound dressings that trick bacteria into suicide.

Health & MedicineChili pepper holds hot prospects for painfree dieting
A cousin of the chemical that packs the heat in chilis not only can rev up the body’s metabolism but actually encourage it to preferentially burn fat, according to a new trial in obese men and women. And the kicker: The molecule is itself so fat that it can’t fit into the receptors that would ordinarily register pain.

Health & MedicineBody makes its own morphine
A study in mice suggests other mammals, including humans, can produce the painkiller in their bodies.
-
AgricultureRural ozone can be fed by feed (as in silage)
Livestock operations take a lot of flak for polluting. Researchers are now linking ozone to livestock, at least in one of the nation's most agriculturally intense centers. And here the pollution source is not what comes out the back end of an animal but what’s destined to go in the front.

ChemistryFrom movies you’ll love to drugs you’ll take
A new method picks out promising drug compounds by computer, in much the same way Netflix recommends DVDs to its customers.
-
Materials SciencePhysicists untangle the geometry of rope
Equations explain why winding fibers together does the job, no matter what they’re made of.

ChemistrySuperheavy element 117 makes debut
An international team of researchers fill a gap in the periodic table, and lay another stepping stone along the path to the “island of stability.”

ChemistryStudy reports hints of phthalate threat to boys’ IQs
You may have a hard time spelling phthalates, but there’s no avoiding them. They’re in the air you breathe, water you drink and foods you eat. And this ubiquity may carry a price, particularly for young boys, emerging data suggest. Including a drop in their IQ.

LifeResearchers figure out how flies taste water
A study identifies the cell membrane protein that flies use to detect water’s flavor.

ChemistrySkin as a source of drug pollution
Traces of over-the-counter and prescription meds taint the environment. The presumption Ì and it's a good one Ì has been that most of these residues come from the urine and solid wastes excreted by treated patients. But in some instances, a leading source of a drug may be skin Ì either because the medicine was applied there or because people sweat it out.
