Baby’s first bacteria depend on birth route
C-section newborns may harbor fewer helpful microbes than infants born vaginally.

Lucy fossil gets jolted upright by Big Man
Scientists have unearthed a 3.6-million-year-old partial hominid skeleton that may recast the iconic species as humanlike walkers.

Feds probe Gulf spill health risks
The Institute of Medicine will be hosting a small public workshop in New Orleans, June 22 and 23, on possible health risks to Gulf coast residents and workers in the wake of the catastrophic BP oil spill. A June 16 congressional hearing previewed some of the concerns likely to arise at the meeting. They ranged from potential long-terms risks of DNA damage to claims that BP failed to provide protective gear to contract crews hired to clean up oil.

Vitamin B6 linked to lowered lung cancer risk
High levels of folate and the amino acid methionine also seem to help, a new study finds.

Loop Current will determine spill’s ultimate fate
Oceanographers track a newly formed eddy in the Gulf of Mexico and where it might carry oil.

Citation 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.

Different berries, similar cancer-fighting effects
Animal tests suggest that esophageal and breast cancer might make good targets for several types of berries as dietary supplements.

Crude 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.

First Mexican-American and African-American genomes completed
Studies hint that genetic diversity among Native Americans may rival that seen in some African populations.
