| Researchers optically levitate a glowing, nanoscale diamond Posted: 12 Aug 2013 05:25 PM PDT Researchers have measured for the first time light emitted by photoluminescence from a nanodiamond levitating in free space.  |
| New twist in the graphene story: Tiny twist in bilayer graphene may solve a mystery Posted: 12 Aug 2013 12:51 PM PDT Researchers have discovered that in the making of bilayer graphene, a tiny structural twist arises that can lead to surprisingly strong changes in the material's electronic properties.  |
| More realistic simulated cloth for more realistic video games and movies Posted: 12 Aug 2013 12:51 PM PDT Computer scientists have developed a new model to simulate with unprecedented accuracy on the computer the way cloth and light interact. The new model can be used in animated movies and in video games to make cloth look more realistic. Existing models are either too simplistic and produce unrealistic results; or too complex and costly for practical use.  |
| Microentrepreneurs may be an untapped market for product design Posted: 12 Aug 2013 09:14 AM PDT Designing products for the developing world can be a hit-or-miss endeavor: While there may be a dire need for products addressing problems, such as access to clean water, sanitation and electricity, designing a product that consumers will actually buy is a complicated process. More often than not, such products -- even those that are distributed at no charge -- go unused due to poor quality, unreliability or differences in cultural expectations.  |
| Posted: 12 Aug 2013 09:13 AM PDT Researchers have discovered an efficient process for hydrogen biocatalysis. They developed semi-synthetic hydrogenases, hydrogen-generating enzymes, by adding the protein's biological precursor to a chemically synthesized inactive iron complex. From these two components, the biological catalyst formed spontaneously in a test tube.  |
| Simulating flow from volcanoes and oil spills Posted: 12 Aug 2013 09:11 AM PDT Some time around 37,000 BCE a massive volcano erupted in the Campanian region of Italy, blanketing much of Europe with ash, stunting plant growth and possibly dooming the Neanderthals. While our prehistoric relatives had no way to know the ash cloud was coming, a recent study provides a new tool that may have predicted what path volcanic debris would take.  |
| Cosmology in the lab using laser-cooled ions Posted: 12 Aug 2013 07:25 AM PDT Scientists would love to know which forces created our universe some 14 billion years ago. How could -- due to a breaking of symmetry -- matter, and thus stars and galaxies, be created from an originally symmetrical universe in which the same conditions prevailed everywhere shortly after the Big Bang? Now, the Big Bang is an experiment that cannot be repeated. But the principle of symmetry and its disturbance can definitely be investigated under controlled laboratory conditions.  |
| Posted: 09 Aug 2013 08:48 AM PDT Physicists show why quantum transport can be close to optimal even in disordered molecular structures.  |
