| Scientists play ping-pong with single electrons Posted: 21 Sep 2011 10:45 AM PDT Researchers have moved an individual electron along a wire, batting it back and forth over 60 times, rather like the ball in a game of ping-pong.  |
| Carnivorous plant inspires coating that resists just about any liquids Posted: 21 Sep 2011 10:45 AM PDT Adopting the pitcher plant's slick prey-catching strategy, a group of applied scientists have created a material that repels just about any type of liquid, including blood and oil, and does so even under harsh conditions like high pressure and freezing temperatures. The bio-inspired liquid repellence technology should find applications in biomedical fluid handling, fuel transport, and anti-fouling and anti-icing technologies. It could even lead to self-cleaning windows and improved optical devices.  |
| New 'smart window' system with unprecedented performance Posted: 21 Sep 2011 10:23 AM PDT A new "smart" window system has the unprecedented ability to inexpensively change from summer to winter modes, darkening to save air conditioning costs on scorching days and returning to crystal clarity in the winter to capture free heat from the sun, scientists are reporting.  |
| Producing flexible CIGS solar cells with record efficiency Posted: 21 Sep 2011 10:17 AM PDT New technology has yielded flexible solar cells with an 18.7% record efficiency. Key to the breakthrough is the control of the energy band gap grading in the copper indium gallium (di)selenide semiconductor, also known as CIGS, the layer that absorbs light and converts it into electricity. Scientists achieved this by controlling the vapor flux of elements during different stages of the evaporation process for growing the CIGS layer.  |
| New source of super-chilled neutrons provides tools for understanding fundamental physics concepts Posted: 21 Sep 2011 09:03 AM PDT Research into fundamental constants of nature and the search for new particles will benefit from new production method for ultra-cold neutrons.  |
| Posted: 21 Sep 2011 09:00 AM PDT The discovery that a protein in insect skin is responsible for protecting the insect as it molts its skin opens the possibilities for selective pest control and new biomaterials like football padding or lightweight aircraft components. It also debunks a more than 50-year-old belief about the protective shell of insects.  |
| Could the Higgs boson explain the size of the universe? Posted: 21 Sep 2011 08:59 AM PDT The race to identify the Higgs boson is on at CERN. This Holy Grail of particle physics would help explain why the majority of elementary particles possess mass. The mysterious particle would also help us understand the evolution of the universe from the moment of its birth, according to a group of physicists. If their theory is verified with data from the Planck satellite, it would clear up several questions about the universe, past and future.  |
| Posted: 21 Sep 2011 06:36 AM PDT Researchers have devised a mathematically rich analytic approach to account for often-missing thermodynamic and molecular parameters in molecular dynamic simulations. The new approach returns atomistic-level data into the time frame of the macroscopic world.  |
| An angry bird in the sky: Lambda Centauri Nebula Posted: 21 Sep 2011 04:54 AM PDT A new image from the Wide Field Imager on the MPG/ESO 2.2-metre telescope reveals the Lambda Centauri Nebula, a cloud of glowing hydrogen and newborn stars in the constellation of Centaurus (The Centaur). The nebula, also known as IC 2944, is sometimes nicknamed the Running Chicken Nebula, from a bird-like shape some people see in its brightest region.  |
| New theory explains collapse of World Trade Center's Twin Towers Posted: 21 Sep 2011 04:47 AM PDT According to a theory advanced by a materials scientist in Norway, a mixture of water from sprinkler systems and molten aluminum from melted aircraft hulls created explosions that led to the collapse of the World Trade Center's Twin Towers in Manhattan on Sept. 11, 2001.  |
| New material synthesized: Graphene nanoribbons inside of carbon nanotubes Posted: 14 Sep 2011 04:31 AM PDT Physicists from Sweden and Finland have found an efficient way to synthesize graphene nanoribbons directly inside of single-walled carbon nanotubes.  |
