This ESOcast 30: introduces the VLT Survey Telescope (VST), the latest addition to ESO's Paranal Observatory. This new telescope has just made its first release of impressive images of the
southern sky. The VST is a stateof the art 2.6 metre telescope, with the huge 268-megapixel camera OmegaCAM at its heart. It is designed to map the sky both quickly and with very fine image quality.
It is a visible-light telescope that perfectly complements ESO's VISTA infrared survey telescope. New images of the Omega Nebula and the globular cluster Omega Centauri demonstrate the VST's
power. Streamed by www.AllThingsScience.com

A wave of ambitious social-network experiments is underway in the U.S. and Europe to track our movements, probe our relationships and, ultimately, affect the individual choices we all make. WSJ's
Robert Lee Hotz reports.
Aneurysm repair is a mechanical solution to the problem of progressive expansion of abdominal aortic aneurysm and the risk of rupture. Although open surgical repair, which has been the established
approach, is very effective, it carries substantial risks from the extensive surgical procedure. Endovascular repair was developed to reduce the risks associated with open surgery and to provide a
treatment option for patients who are not deemed to be surgical candidates.
