Rural 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.

IOM: Manufacturers should help Americans cut back on salt
Americans have developed an unhealthy love affair with this savory condiment. And 40 years of haranguing people about their overconsumption has “generally failed to make a dent in Americans’ intake,” according to the Institute of Medicine, a research arm of the National Academy of Sciences. A new report it releases April 21 will ask the Food and Drug Administration to set lower ceilings on how much salt can be added to processed foods.

Lung disease: A human cost of ‘worn’ denim
Manufacturers have for decades prematurely aged apparel by sandblasting the fabric. A new study out of Turkey finds that some workers charged with giving denim a well-worn look pay a high price: the development of silicosis – an irreversible and potentially lethal lung disease.

Mercury surprise: Rice can be risky
A new study out of China shows that for millions of people at risk of eating toxic amounts of mercury-laced food, fish isn't the problem. Rice is.

Breast implants may mask early cancer
Breast augmentation is the leading cosmetic surgery in North America, with roughly 400,000 procedures a year in the United States alone. A study now finds some evidence that breast implants may hinder early detection of breast malignancies. The good news: This didn’t affect survival.

Gulf War Syndrome real, Institute of Medicine concludes
U.S. veterans who claim to suffer from Gulf War Syndrome just received powerful new ammunition against arguments that their symptoms are trivial, if not altogether fictional. On April 9, the health arm of the National Academy of Sciences issued a report that concludes military service in the Persian Gulf War has not only been a cause of post-traumatic stress disorder in some veterans but also is "associated with multisymptom illness” – as in Gulf War Syndrome.

Traffic’s soot elevates blood pressure
Legions of studies have shown that air pollution can harm the heart and blood vessels. Scientists now have linked airborne concentrations of tiny black-carbon particles — soot — with increasing blood pressure in older men. They also showed that the genes we inherit appear to play a big role in determining our vulnerability to soot’s pressurizing impacts.

D.C. as science mecca
Not only is the D.C. area a center of research policy, but many scientific societies also call this place home. Still, I was a bit surprised to find out that fully one in 10 of our area residents work in research-related fields. That’s 50 percent more than in the next biggest hive of research: the New York City metro area.

U.S. health system not adequately prepared for the aging sick
Is the U.S. healthcare system prepared to deal with aging patients who have at least two chronic medical conditions — ones that will each require at least a year of ongoing treatment? “Current indications suggest that it is not,” two physicians at the Department of Health and Human Services conclude.

Study 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.

Skin 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.

Mothballs deserve respect
I don’t use mothballs — except sometimes to sprinkle down the burrows of animals excavating tunnels beneath the deck floor of my pergola. It’s the most effective stop-work order for wildlife that I’ve found. But I won’t use these stinky crystals inside my home because they scare me. And those fears appear justified, according to Linda Hall of the California Environmental Protection Agency.
