    Pesticide in womb may promote obesity, study finds

    One-quarter of babies born to women who had relatively high concentrations of a DDT-breakdown product in their blood grew unusually fast for at least the first year of life. Not only is this prevalence of accelerated growth unusually high, but it’s also a worrisome trend since such rapid growth during early infancy has — in other studies — put children on track to become obese.

    Warming is accelerating global water cycle

    Fresh water evaporates from the oceans, rains out over land and then runs back into the seas. A new study finds evidence that global warming has been speeding up this hydrological cycle recently, a change that could lead to more violent storms. It could also alter where precipitation falls — drying temperate areas, those places where most people now live.

    Contemplating an Arctic oil spill

    The waters off northern Alaska may be “the largest oil province in the United States” after the Gulf, notes Edward Itta, a native of Barrow, Alaska. He is also mayor of the North Slope Borough, an 88,000-square-mile jurisdiction that runs across the upper part of the state. And in a September 27 videoconference with the National Commission on the BP Deepwater Horizon Oil Spill and Offshore Drilling, he tried to impress upon the commissioners just how remote his neck of the tundra is.

    BP oil: Gulf sediment at risk, oceanographer claims

    Most of BP’s spilled oil remains in the Gulf — with little sign of degrading, according to Ian MacDonald of Florida State University. And much of this surviving oil could be in sediment or on its way there, the scientist reported at a September 27 meeting in Washington, D.C.
