FEATURED BLOG: One all-too-familiar side effect of international trade is the outsourcing of jobs, or their movement from developed nations (where production costs are relatively high) to regions where a variety of costs are relatively low.
But the geographic separation of production and consumption also has a less reco...gnized, or at least a less frequently discussed, effect — the "outsourcing" of greenhouse gas emissions...

Pandemic H1N1 influenza may seem daunting, but two new studies reveal that you’ve got it in you to fight the flu.
Two separate research teams have cataloged interactions between the H1N1 influenza virus and human cells, with one group reporting that human cells already contain powerful antiflu agents that also help defe...nd against other viral infections, including West Nile virus and dengue....

Great. Just in time for the holidays, researchers are fueling the debate about which side of the family is responsible for your more undesirable traits.
Genetic variations can either contribute to disease risk, or help protect against disease, depending on which parent passes along the variant, researchers at deCODE gen...etics in Iceland and colleagues report in the Dec. 17 Nature. The team uncovered common single-letter genetic changes — called SNPs, short for single nucleotide polymorphisms — that were associated with diseases only when the change was inherited from a particular parent....

It looks like nearsightedness is on the rise in the United States.
Researchers compared eyesight information for more than 4,400 people tested in 1971 and 1972 with data from another set of 8,300 people tested from 1999 to 2004. This broad survey of 12,700 people showed that 25 percent of those examined in the early 197...0s were deemed to be nearsighted, compared with 42 percent examined three decades later, the researchers report in the December Archives of Ophthalmology. That’s an increase of 66 percent....
