Perchlorate is not yet a household word in many parts of the country. But it may becomes one if Sen. Barbara Boxer has her way. Perchlorate – an ingredient in solid rocket fuel, fireworks, flares and explosives – taints drinking-water supplies around the nation, not to mention plenty of foods. In animal tests, the pollutant perturbs thyroid-hormone signaling. If such hormonal messages are muted or garbled in the womb or shortly after birth, an animal may suffer developmental – even cognitive – retardation. So one might think that U.S. regulatory agencies would have set maximum allo...Found in: Body & Brain, Ecology, Environment, Nutrition and Science & Society

With Uncle Sam pushing the production of ethanol for fuel, U.S. farmers are planting more corn than at any time since World War II, and garnering premium prices for each harvested bushel. But many livestock operations are getting hit with a double whammy: higher feeds costs and corn-derived feed that’s carrying triple the normal load of fungal poisons.Found in: Agriculture, Environment, Food Science, Molecules, Nutrition and Science & Society
