The latest fashion: Graphene edges can be tailor-made Posted: 23 Jan 2015 04:02 PM PST Theorists show it may be possible to tune graphene edges by varying heat and force as graphene is fractured. Edge configurations affect graphene's electronic and mechanical properties, which are important for applications.

Scientists slow down the speed of light travelling in free space Posted: 23 Jan 2015 11:41 AM PST Scientists have managed to slow photons in free space for the first time. They have demonstrated that applying a mask to an optical beam to give photons a spatial structure can reduce their speed.

Boston's leaky pipes release high levels of heat-trapping methane Posted: 23 Jan 2015 08:07 AM PST A research team estimates that each year about 15 billion cubic feet of natural gas, worth some $90 million, escapes the Boston region's delivery system. The findings have implications for other regions, especially cities that, like Boston, are older and rely on natural gas for a significant and increasing portion of their energy needs. While policymakers have focused on the production end of the natural gas supply chain--wells, off-shore drilling platforms, and processing plants--much less attention has been paid to the downstream gas delivery infrastructure.

Silver nanowires demonstrate unexpected self-healing mechanism: Potential for flexible electronics Posted: 23 Jan 2015 08:07 AM PST Researchers found that silver nanowires can withstand strong cyclic loads, which is a key attribute needed for flexible electronics.

Calculating the future of solar-fuel refineries Posted: 23 Jan 2015 08:07 AM PST A team of engineers has developed a new tool to help engineers better gauge the overall yield, efficiency and costs associated with scaling solar-fuel production processes up into large-scale refineries.

New technique helps probe performance of organic solar cell materials Posted: 23 Jan 2015 08:07 AM PST Researchers have developed a technique for determining the role that a material's structure has on the efficiency of organic solar cells, which are candidates for low-cost, next generation solar power. The researchers used the technique to determine that materials with a highly organized structure at the nanoscale are not more efficient at creating free electrons than poorly organized structures -- a finding which will guide future research and development efforts.

New technique for producing cheaper solar energy suggested by research Posted: 23 Jan 2015 08:07 AM PST Pioneering new research could pave the way for solar energy to be converted into household electricity more cheaply than ever before. The global PV market has experienced rapid growth in recent years due to renewable energy targets and CO2 emission controls.

Stalking versus cyberstalking: Effects on victims, their responses compared Posted: 23 Jan 2015 08:07 AM PST The devastating effects of stalking and cyberstalking – harassing or threatening communication via the Internet – are explored in a new study. Key among the findings is that victims of cyberstalking engage in more 'self-protective' behaviours -- such as changing their normal routines or getting a new email address -- than victims of stalking.

Alamo impact crater: New study could double its size Posted: 23 Jan 2015 07:25 AM PST Carbonate rock deposits found within the mountain ranges of south-central Nevada, USA, record evidence of a catastrophic impact event known as the Alamo impact. This event occurred roughly 382 million years ago when the ancient seafloor was struck and a submarine crater was formed. The crater was filled-in with fragmented rock, and later with more typical ocean deposits, as the energy from the impact lessened and the environment returned to normal.

How does the universe creates reason, morality? Posted: 23 Jan 2015 07:22 AM PST Recent developments in science are beginning to suggest that the universe naturally produces complexity. The emergence of life in general and perhaps even rational life, with its associated technological culture, may be extremely common, argues a scientist.

Yes, black holes exist in gravitational theories with unbounded speeds of propagation Posted: 23 Jan 2015 07:22 AM PST Gravitational theories with broken Lorentz invariance have attracted a great deal of interest as they provide a test-bed of LI and offer a mechanism to improve their ultraviolet behavior, so that the theories may be renormalizable. However in such theories, particles can travel with arbitrary velocities and black holes may not exist at all. In contrast to this expectation, it has been shown that an absolute horizon exists, which traps signals despite infinitely large velocities.

H.E.S.S. finds three extremely luminous gamma-ray sources Posted: 23 Jan 2015 07:22 AM PST The High Energy Stereoscopic System telescopes have again demonstrated their excellent capabilities in searching for high-energy gamma rays.

New breast exam nearly quadruples detection of invasive breast cancers in women with dense breast tissue Posted: 23 Jan 2015 07:16 AM PST Molecular Breast Imaging (MBI) is a supplemental imaging technology designed to find tumors that would otherwise be obscured by surrounding dense breast tissue on a mammogram. The new breast imaging technique nearly quadruples detection rates of invasive breast cancers in women with dense breast tissue, according to the results of a major study.

Massive chip design savings to be realized Posted: 23 Jan 2015 05:17 AM PST IT researchers have developed a programming language making the massive costs associated with designing hardware more manageable. Chip manufacturers have been using the same chip design techniques for twenty years now. The current process calls for extensive testing after each design step - a massively expensive state of affairs. The newly developed, so-called  functional  programming language makes it possible to prove, in advance, that a design transformation is a hundred percent error-free.

Improvements in transistors will make flexible plastic computers a reality Posted: 23 Jan 2015 05:12 AM PST Researchers revealed that improvements should soon be expected in the manufacture of transistors that can be used, for example, to make flexible, paper-thin computer screens.

Revolutionary device found to lower blood pressure Posted: 22 Jan 2015 04:39 PM PST A revolutionary device has been shown to significantly lower blood pressure among patients with uncontrolled high blood pressure, compared to those treated with usual drug measures. "High blood pressure is very dangerous and leads to hospital treatment, stroke, heart attack and chronic kidney disease. We must find better means of treating high blood pressure as drugs do not work for everyone and the Coupler is a big step forward in our search for alternative treatment," said the lead investigator.

Falls in blood pressure, cholesterol have saved 20,000+ lives in England Posted: 22 Jan 2015 04:39 PM PST Falls in blood pressure and total cholesterol staved off more than 20,000 deaths from coronary heart disease in England between 2000 and 2007, shows a mathematical analysis. The impact of statins was greatest among the most affluent in the population, suggesting that these drugs have helped maintain health inequalities between rich and poor, say the researchers.

Scientists search for new ways to deal with U. S. uranium ore processing legacy Posted: 22 Jan 2015 01:59 PM PST Researchers are trying to find out why uranium persists in groundwater at former uranium ore processing sites despite remediation of contaminated surface materials two decades ago. They think buried organic material may be at fault, storing toxic uranium at levels that continue to pose risks to human health and the environment, and hope their study will pave the way for better long-term site management and protection of the public and environment.

Rosetta data reveals more surprises about comet 67P Posted: 22 Jan 2015 11:54 AM PST As the Rosetta spacecraft orbits comet 67P/Churyumov-Gerasimenko, an international team of scientists have discovered that the comet's atmosphere, or coma, is much less homogenous than expected and comet outgassing varies significantly over time.

Rosetta data give closest-ever look at a comet Posted: 22 Jan 2015 11:54 AM PST On Nov. 12, 2014, the Rosetta mission's Philae lander touched down on the surface of comet 67P/Churyumov-Gerasimenko. While this achievement gained lots of headlines, it was only the beginning for researchers back on Earth. New data provides the closest and most detailed look at a comet that scientists have ever seen.

Gas variations are suggestive of seasons on comet Chury Posted: 22 Jan 2015 11:18 AM PST Comet 67P/Churyumov-Gerasimenko continues to reveal more of its secrets: Researchers have detected considerable variations in the gas escaping from the comet. This could amount to seasonal changes on the tiny celestial body. Meanwhile, the camera OSIRIS on board the Rosetta comet probe is revealing new details of the surface of Chury.
