TechElection projections for science investments
The November 2, mid-term election results are in (mostly) and pundits are billing it as a historic turnabout. With a divided Congress, passing legislation — never an easy task — risks becoming harder still. And with fiscal austerity having been a leading campaign issue for the newbies, R&D is unlikely to see a major boost in federal funding during the next two years.

TechPlenty of foods harbor BPA, study finds
Some communities have banned the sale of plastic baby bottles and sippy cups that are manufactured using bisphenol A, a hormone-mimicking chemical. In a few grocery stores, cashiers have already begun donning gloves to avoid handling thermal receipt paper whose BPA-based surface coating may rub off on the fingers. But how’s a family to avoid exposure to this contaminant when it taints the food supply?

Health & MedicineMRIs pinpoint time of stroke
Doing a magnetic resonance scan promptly when a patient arrives at a hospital could render more patients eligible for a time-sensitive clot-busting therapy that can limit brain damage.

ChemistrySkin is no barrier to BPA, study shows
The new finding suggests handling store receipts could be a significant source of internal exposure to the hormone-mimicking chemical.

HumansBP gusher left deep sea toxic for a time, study finds
In the early weeks after the damaged BP well began gushing huge quantities of oil and gas, a toxic brew was developing deep below the surface in plumes emanating from the wellhead. Finned fish and marine mammals probably steered well clear of the spewing hydrocarbons. But planktonic young — larval critters and algae that ride the currents — would have been proverbial sitting ducks.

HumansDeep African roots for toolmaking method
A method for trimming stone-tool edges appeared 75,000 years ago in southern Africa, archaeologists contend, long before previous evidence of the practice.

Life1000 Genomes pilot a hit with geneticists
The first stage of a project to probe human genetic diversity has found millions of new variations.

Health & MedicinePancreatic cancer years in the making
A decade elapses from the first cancer-related mutation to tumor formation, and several more years pass until the disease spreads to other organs, a new study finds. The work raises the possibility that a usually deadly malignancy can be treated before it’s too late.
