Today's selection of science news. Links are normally to press releases on EurekAlert (at the bottom end I may also add a couple of newspaper stories). I include quotes from the summary in italics in cases where the title alone doesn't reveal what the story is about. My own thoughts appear without italics if I have any.
Not much going on today, apparently:
Ancient bony fish forces rethink of how sharks evolved
A new twist on DNA origami

'Wild West' mentality lingers in modern populations of US mountain regions
Scientists looked at links between the personality profiles of over 3.3m US residents and the "topography" of 37,227 ZIP codes. Distinct psychological mix associated with mountain populations is consistent with theory that harsh frontiers attracted certain personalities. Researchers argue this may be residual from US frontier expansion during the 19th century, as personality pattern is strongest in the West.
