    Preventing disastrous offshore spills may require space-program diligence

    As crude oil continues to spew from the Gulf of Mexico seafloor — two weeks now after the Deepwater Horizon accident and sinking — questions continue to surface about what went wrong. To my mind, what went wrong was almost blind optimism on the part of industry, regulators, the states and the public. And any niggling doubt about the wisdom of that optimism was likely assuaged by at least a little greed.

    BP oil rig’s sinking and gushing crude raise questions

    Around 10 p.m. local time on April 20, the Deepwater Horizon — a floating oil-drilling platform leased to British Petroleum — suffered an explosion and fire about 40 miles off the Louisiana coast. While the aftermath of that devastating accident is now being observed and chronicled in painful detail, even the most basic features of what triggered it remain sketchy.

    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.
