Turning to Biomechanics to Build a Kinder, Gentler Rib Spreader

DURHAM, N.C. -- The sign on the door at the renovated tobacco warehouse reads "Physcient." Inside are a few rooms that, depending on where you look, seem like an artist's studio, a machine shop or a natural history museum. A lathe stands next to a drill press; along other walls are vises, huge enamel-red C-clamps, microscopes and plywood frames covered in electronics. But there are also reed-woven sculptures of insects called water boatmen hanging on the walls, along with glass-fronted boxes holding preserved flying dragon lizards. Casts of human rib bones are scattered on tables. A huge cast of a fearsome pair of fish jaws rests on a row of books...

Bright Lights, Rich Cities

Fly into a city on a clear night and you'll enjoy a jeweled panorama below. Starkly lit skyscrapers, yellow glows from the windows of scattered homes, and roads pulsing white and red as cars speed over highways and crawl along residential streets. All of this electricity usage tends to indicate that a city has money to spend. And, indeed, in a new study, economists have shown that satellite measurements of an area's lights reveal how economically developed it is...

Massive Chilean Dams Approved

Officials in Chile have approved a controversial US$3.2-billion project to construct five hydropower dams in Patagonia. The HidroAysén project--a collaboration between the country's two biggest energy firms--plans to generate 2,750 megawatts of power by damming two major rivers, the Baker and the Pascua. But it must first seek approval for a 2,300-kilometre transmission line, costing another US$3.8 billion, that would carry power to Santiago...
