Resting brain activity associated with spontaneous fibromyalgia pain
A recent study from researchers at Massachusetts General Hospital and University of Michigan provides the first direct evidence of linkage between elevated intrinsic (resting-state) brain connectivity and spontaneous pain intensity in patients with fibromyalgia (FM). This research shows an interaction of multiple brain networks, offering greater understanding of how pain arises. Details of the study appear online and in the August issue of Arthritis & Rheumatism, a journal published by Wiley-Blackwell on behalf of the American College of Rheumatology.

Discovered: Audubon's first engraving of a bird
In 1824, three years before he began to publish his famous "double elephant folio" The Birds of America, John James Audubon (1785-1851), the eminent artist of American birds and animals, created a drawing of a running grouse for use in the design for a New Jersey bank note. Although the artist mentions the drawing and the resulting engraved paper money in two separate diary entries, no one has ever been able to locate or identify such an illustration.

Small increases in vaccine cost can cause large gaps in protection
Public immunization efforts may be much more sensitive than previously realized to small changes in the perceived costs or risks of vaccination, scientists at Harvard University report this week. In some cases, the spread of vaccine avoidance via social networks can make the difference between a minor, localized outbreak and an epidemic four times as large.

Good and bad in the hands of politicians
"In laboratory tests, right- and left-handers associate positive ideas like honesty and intelligence with their dominant side of space and negative ideas with their non-dominant side," says Daniel Casasanto of the Max Planck Institute for Psycholinguistics in Nijmegen, Netherlands. To find out whether people link 'good' with 'dominant' beyond the laboratory, Casasanto and co-author Kyle Jasmin examined spontaneous gestures during positive and negative speech in the final debates of the most recent US presidential elections. The 2004 and 2008 elections involved two right-handers (Kerry, Bush) and two left-handers (Obama, McCain). Casasanto and Jasmin found that right-handed candidates made a greater proportion of right-hand gestures when expressing positive ideas and left-hand gestures when expressing negative thoughts. But the opposite was found for the left-handers, who favored their left hand more for the positive and their right hand for the negative. Obama's 'right-hand man' may be on his left.
