    It's Spud Time

    As 2007 winds down, thoughts naturally turn towards what might lie ahead. Meals rich in high-carb tubers, perhaps? That's what the United Nations would like everyone to contemplate throughout 2008, which it is designating the International Year of the Potato.

    Farmers now harvest more than 300 million tons of potatoes (Solanum tuberosum) worldwide. That makes it the fourth biggest food...

    Juice May Slow Prostate Cancer Growth (with recipe)

    Prostate cancer will claim the lives of an estimated 30,000 men in the United States this year. The second leading cause of cancer death in men, its incidence climbs with age. In Western countries, the disease is reaching nearly epidemic proportions among the elderly. However, the cancer can grow so slowly that many men with prostate cancer will die of something else first.

    Leaden streets

    From San Diego, at a meeting of the Society of Toxicology

    When Arlene L. Weiss and her colleagues found that urban house dust tends to contain more lead the closer it is to a frequently opened window, they reasoned that most of the heavy metal arrives from outside. Their new survey now confirms that street grit is the probable source of lead in urban homes and that flaking paint from...

    Lemon-scented products spawn pollutants

    While prepping for holiday guests, many hosts will deploy cleaners and air fresheners that impart a pleasant lemon or pine scent. Though they can mask stale smells, their fragrant ingredients—under certain conditions—may also be a rich source of indoor pollution, a study finds.

    Several years ago, Charles J. Weschler, a chemist at Telcordia Technologies in Red Bank, N.J., stumbled onto...

    Leaden Gardens

    Soils in many cities of the United States carry a poisonous legacy: heavy concentrations of lead. The metal was deposited for years as fallout from flaking leaded house paint and the emissions of cars burning leaded gasoline. Recognizing the threat posed by tainted soil, environmental scientists have warned that growing edible plants in soils near streets or within several feet of homes and...

    UV-pollutant combo hits tadpoles hard

    From New Orleans, at the e.hormone 2003 Conference

    Many of the studies documenting a global decline in amphibians have linked the shrinking populations with exposure to excessive ultraviolet (UV) sunlight or to pollutants, especially ones with a hormonal effect. Biologists now find that slightly elevated UV exposure reduces the chance that tadpoles will become frogs. That chance...

    POPs treaty enacted

    On Oct. 23, a new international treaty–the Protocol on Persistent Organic Pollutants (POPs)–went into effect, although the United States hasn't signed on. Brokered under the aegis of the United Nations, the POPs treaty calls for reduction or elimination of toxic chemicals that are long-lived and have the propensity to travel long distances.

    When first drafted in 2000, this treaty looked...

    As If You Needed Another Reason to Eat Strawberries (with recipe)

    Whether draped atop shortcake, cooked with rhubarb and slathered over vanilla ice cream, or downed in the garden just after picking, strawberries are one of summer's delights. Now, scientists at Cornell University find that this fragile fruit not only tastes great and contains vitamins but also may offer surprisingly potent benefits in the body's fight against cancer and heart disease.

    Secrets of Dung: Ancient poop yields nuclear DNA

    Researchers have extracted remnants of DNA from an unlikely source: the desiccated dung of an extinct ground sloth that lived in Nevada at the height of the last ice age. The feat is the first recovery of genetic material from cell nuclei of fossils that haven't been sheathed in permafrost. It suggests that scientists may be overlooking caches of fossil DNA preserved in warm arid environments...

    Lead delays puberty

    In children, even trace residues of lead can wreak harm. One recent study reported evidence of IQ deficits in children with blood concentrations of the metal below 5 micrograms per deciliter (g/dl) (SN: 4/26/03, p. 269: Available to subscribers at Traces of lead cause outsize harm), an amount found in 90 percent of U.S. kids. Now, epidemiologists have turned up evidence that similarly low...
