Trumpler 14: Bright Young Stars Mix It Up
Credit: NASA/CXC/Penn State/L.Townsley et al. Chandra's image of the star cluster Trumpler 14 shows about 1,600 stars and a diffuse glow from hot multimillion-degree X-ray-producing gas. The cluster has one of the hightest concentrations of massive, luminous stars in the Galaxy. Located on the edge of a giant molecular cloud, it is part of the Carina Complex which contains at least 8 star clusters.

New Microprinting Technique Improves Nanoscale Fabrication
A demonstration of microdisplacement printing, in which a weakly bound film is displaced by contact stamping with molecules that bind more strongly to the substrate. This process leaves a patterned film with regions of strongly bound molecules (where the weakly bound molecules were displaced) and regions of the remaining weakly bound molecules.
Novel Technique Offers New Look at Ancient Diets
Scale-sensitive fractal analysis. a-e, Relative area is calculated by dividing the area of a surface, calculated using triangles of a given scale in a virtual tiling algorithm (a, b, c), by the projected area of the surface (d). Relative area can then be plotted against scale in a log-log plot (e). Asfc30 is a scale-sensitive measure of roughness and is the slope of the steepest part of the curve fitted to the plot of relative area over scale, multiplied by -1,000.
Brain Scientists Offer Insight Into Vision

Scientists Measure How Deep "Deep Impact" Was, With X-rays
False-color image of Comet Tempel 1 taken on 1 July 2005 with the Swift Ultraviolet Optical Telescope. The picture was formed from images taken separately through V, B, U, and Ultraviolet filters and corrected for the comet's motion before being combined. As a result, the background stars appear as a series of images in different colours.
