Refrigerated trucks to keep their cool thanks to fuel cell technology Posted: 23 Aug 2013 01:38 PM PDT Grocery merchants in Texas, California and New York will soon have ice cream, frozen foods and fresh produce delivered by tractor trailers whose refrigeration units are powered by fuel cells, which will do the work normally done by a small diesel engine to keep the cargo at the proper temperature while the trucks are making deliveries.

Two become one with the 3-D NanoChemiscope: Unique surface analysis instrument Posted: 23 Aug 2013 06:11 AM PDT The 3D NanoChemiscope is a miracle of state-of-the-art analysis technology. As a further development of well-known microscopic and mass spectroscopic methods, it maps the physical and chemical surfaces of materials down to the atomic level. This instrument, which is unique in the world, not only delivers high-definition images; it also knows what it is "seeing".

A fluffy disk around a baby star Posted: 23 Aug 2013 06:11 AM PDT Astronomers have observed a disk around the young star RY Tau (Tauri). The team's analysis of the disk shows that a "fluffy" layer above it is responsible for the scattered light observed in the infrared image. Detailed comparisons with computer simulations of scattered light from the disk reveal that this layer appears to be a remnant of material from an earlier phase of stellar and disk development, when dust and gas were falling onto the disk.
