Science & SocietyCitation inflation
Many journals – and the authors who publish their novel data and analyses in them – rely on “impact factors” as a gauge of the importance and prestige of their work. However, a new analysis turns up subtle ways that journals can game the system to artificially inflate their impact factor.

HumansCrude pick-ups
To date, 400 skimmers have retrieved some 18 million gallons of oiled water from the BP Gulf spill, according to Coast Guard Admiral Thad Allen during a June 11 press briefing. After removing the entrained water, this translates to between 1.8 million and 2.7 million gallons of crude oil. Another 3.8 million gallons of oil have been burned at sea. Four million gallons more have been collected through a near-mile-long riser tube and a containment cap fitted over the broken Deepwater Horizon wellhead.

HumansBP spill: Gulf is primed to heal, but . . .
Every day, Mother Nature burps another 1,000 barrels of crude into the Gulf of Mexico, along with additional quantities of natural gas. Normally, these hydrocarbons don’t stick around long because local bacteria have evolved to eat them about as fast as they appear. Which is potentially good news, she explained in testimony during a pair of June 9 House subcommittee events on Capitol Hill, because those bugs are now in place to begin chowing down on the oil and gas entering the Gulf from BP's damaged Deepwater Horizon well.
