New Nanotech Fabric Never Gets Wet 231

Posted by timothy from the good-for-lining-lunchboxes dept.
holy_calamity writes "New Scientist reports on a simple coating for polyester that renders it unwettable — even after two months underwater it emerges dry to the touch. Water cannot attach to the new fabric thanks to nanostructured filaments and a structure that traps a constant air layer. One potential use is for low-drag swim wear."

Galactic Traffic Patterns 81

Posted by Hemos
eldavojohn writes "Using Hubble, researchers have noticed traffic patterns of stars within our own galaxy. From the article, 'Researchers analyzed 47 Tucanae, the second largest cluster in the Milky Way's galactic neighborhood, and determined the cluster sorts out stars according to their masses. Due to the associated gravitational pull, heavier stars slow down and sink to the cluster's core, while lighter stars pick up speed and zip out to the cluster's periphery.' There is speculation that these movements of stars — although tiny — can have significant implications and possibly result in mass segregation."
