| Chemists develop 'fresh, new' approach to making alloy nanomaterials Posted: 10 Aug 2013 03:37 AM PDT Chemists have figured out how to synthesize nanomaterials with stainless steel-like interfaces. Their discovery may change how the form and structure of nanomaterials are manipulated, particularly those used for gas storage, heterogeneous catalysis and lithium-ion batteries.  |
| On the trail of dark energy: Physicists propose Higgs boson 'portal' Posted: 10 Aug 2013 03:36 AM PDT One of the biggest mysteries in contemporary particle physics and cosmology is why dark energy, which is observed to dominate energy density of the universe, has a remarkably small (but not zero) value. Now, two physicists suggest that the Higgs boson could provide a possible "portal" to physics that could help explain some of the attributes of the enigmatic dark energy and help resolve the cosmological constant problem.  |
| Posted: 10 Aug 2013 03:33 AM PDT Researchers have long been aware of a phenomenon in speech called coarticulation, in which certain sounds are produced differently depending on the sounds that come before or after them. A new study suggests that piano paying also involves coarticulation, with hand muscle contractions differing depending on the sequence of notes played.  |
| Perseid meteors to light up summer skies Posted: 09 Aug 2013 08:48 AM PDT The evening of 12 August and morning of 13 August see the annual maximum of the Perseids meteor shower. This year prospects for watching this natural firework display are particularly good.  |
| New insights into the polymer mystique for conducting charges Posted: 09 Aug 2013 08:46 AM PDT With its ever-escalating pursuit of high efficiency and low cost, the electronics industry prizes understanding specific behaviors of polymers. Now there's help in appreciating the polymer mystique related to the emerging field of molecular conduction in which films of charge-transporting large molecules and polymers are used within electronic devices.  |
| Getting to the core of Fukushima Posted: 07 Aug 2013 08:56 AM PDT Critical to the recovery efforts following the devastating effects of the 2011 tsunami on Japan's Fukushima reactor is the ability to assess damage within the reactor's core. A new study shows that muon imaging may offer the best hope of assessing damage to the reactor cores and locating the melted fuel.  |
| Engineers gain new insight into turbulence that could lead to significant global energy savings Posted: 07 Aug 2013 06:43 AM PDT Scientists have developed a new understanding of how turbulence works, which could help to optimise vehicle performance and save billions in global energy costs.  |
| Diamonds are a laser scientist's new best friend Posted: 07 Aug 2013 06:43 AM PDT Once a James Bond fantasy, diamond-based lasers are now becoming a reality.  |
| Posted: 07 Aug 2013 06:43 AM PDT Scientists can now theoretically construct atomic beams of a particular kind. Physicists have, for the first time, now built a theoretical construct of beams made of twisted atoms. These so-called atomic Bessel beams can, in principle, have potential applications in quantum communication as well as in atomic and nuclear processes.  |
| SkySweeper robot makes inspecting power lines easy and inexpensive Posted: 06 Aug 2013 11:55 AM PDT Mechanical engineers have invented a robot designed to scoot along utility lines, searching for damage and other problems that require repairs. Made of off-the-shelf electronics and plastic parts printed on an inexpensive 3D printer, the SkySweeper prototype could be scaled up for less than $1,000, making it significantly more economical than the two models of robots currently used to inspect power lines.  |
