| Venus' transit and the search for other worlds Posted: 05 Jun 2012 02:10 PM PDT It's the final opportunity of the century to witness the rare astronomical reunion of the sun, Venus and Earth. On Tuesday, June 5 or 6, 2012, depending on your location, Venus will make its presence in the solar system visible from Earth's day side. Using special eye safety precautions, viewers may see Venus as a small dot slowly drifting across the golden disk of the sun.  |
| Nuclear weapon simulations show performance in molecular detail Posted: 05 Jun 2012 12:59 PM PDT US researchers are perfecting simulations that show a nuclear weapon's performance in precise molecular detail, tools that are becoming critical for national defense because international treaties forbid the detonation of nuclear test weapons.  |
| Precise measurement of radiation damage on materials Posted: 05 Jun 2012 11:34 AM PDT Researchers have for the first time simulated and quantified the early stages of radiation damage that will occur in a given material.  |
| Weak bridges identified in Texas Posted: 05 Jun 2012 08:37 AM PDT More than a dozen Gulf Coast bridges in or near Galveston, Texas, would likely suffer severe damage if subjected to a hurricane with a similar landfall as Hurricane Ike but with 30 percent stronger winds, according to researchers.  |
| Faster, more sensitive photodetector created by tricking graphene Posted: 05 Jun 2012 07:28 AM PDT Researchers have developed a highly sensitive detector of infrared light that can be used in applications ranging from detection of chemical and biochemical weapons from a distance and better airport body scanners to chemical analysis in the laboratory and studying the structure of the universe through new telescopes.  |
| Splitting the unsplittable: Physicists split an atom using quantum mechanics precision Posted: 05 Jun 2012 07:28 AM PDT Researchers have just shown how a single atom can be split into its two halves, pulled apart and put back together again. While the word "atom" literally means "indivisible," the laws of quantum mechanics allow dividing atoms -- similarly to light rays -- and reuniting them. The researchers want to build quantum mechanics bridges by letting the atom touch adjacent atoms while it is being pulled apart so that it works like a bridge span between two pillars.  |
| Chiral asymmetry can emerge from maximal symmetry Posted: 05 Jun 2012 04:52 AM PDT Maximally symmetric systems of particles can spontaneously produce two different patterns, which are mirror images of each other, new research shows. The research group is working towards a mathematical design of self-assembling nanomaterials.  |
| Energy-dense biofuel from cellulose close to being economical Posted: 04 Jun 2012 03:19 PM PDT A new process for creating biofuels has shown potential to be cost-effective for production scale, opening the door for moving beyond the laboratory setting.  |
