Computer scientist jailbreaks iOS 7.1.2 Posted: 01 Aug 2014 07:50 AM PDT Security researchers have discovered a way to jailbreak current generation Apple iOS devices -- e.g., iPhones and iPads -- running the latest iOS software.

'Fracking' in the dark: Biological fallout of shale-gas production still largely unknown Posted: 01 Aug 2014 06:12 AM PDT Eight conservation biologists from various organizations and institutions found that shale-gas extraction in the United States has vastly outpaced scientists' understanding of the industry's environmental impact. With shale-gas production projected to surge during the next 30 years, determining and minimizing the industry's effects on nature and wildlife must become a top priority for scientists, industry and policymakers, the researchers said.

Chemists develop MRI technique for peeking inside battery-like devices Posted: 01 Aug 2014 06:12 AM PDT Chemists have developed a method for examining the inner workings of battery-like devices called supercapacitors, which can be charged up extremely quickly and can deliver high electrical power.

When particles fall left and right at the same time: Physicists develop new method to verify quantum entanglement Posted: 01 Aug 2014 06:11 AM PDT It takes only a slight disturbance for a pencil standing on its tip to fall in one direction or another. In the quantum world it is possible in principle for particles of a system to fall both left and right at the same time. Differentiating this "and" state -- the quantum entanglement of particles -- from the classical "or" is an experimental challenge. Scientists have now devised a novel and universal method that enables entanglement verification for states of large atomic systems.

Researchers identify cause of surface barriers of metal-organic frameworks: Relevant to gas storage Posted: 31 Jul 2014 11:56 AM PDT Metal-organic frameworks (MOFs) can take up gases similar to a sponge that soaks up liquids. Hence, these highly porous materials are suited for storing hydrogen or greenhouse gases. However, loading of many MOFs is inhibited by barriers. Scientists now report that the barriers are caused by corrosion of the MOF surface. This can be prevented by water-free synthesis and storing strategies.

Low-grade nonwoven cotton picks up 50 times own weight of oil Posted: 31 Jul 2014 11:55 AM PDT Researchers have recently discovered that low-grade cotton made into an absorbent nonwoven mat can collect up to 50 times its own weight in oil.

Nanostructured metal-oxide catalyst efficiently converts CO2 to methanol, a key commodity for chemicals and fuels Posted: 31 Jul 2014 11:54 AM PDT Scientists have discovered a new catalytic system for converting carbon dioxide (CO2) to methanol-a key commodity used to create a wide range of industrial chemicals and fuels. With significantly higher activity than other catalysts now in use, the new system could make it easier to get normally unreactive CO2 to participate in these reactions.

Misinformation diffusing online Posted: 31 Jul 2014 08:10 AM PDT The spread of misinformation through online social networks is becoming an increasingly worrying problem. Researchers have now modeled how such fictions and diffuse through those networks. They described details of their research and the taxonomy that could help those who run, regulate and use online social networks better understand how to slow or even prevent the spread of misinformation to the wider public.

Scientists shine bright new light on how living things capture energy from the sun Posted: 31 Jul 2014 08:10 AM PDT Scientists may have uncovered a new method of exploiting the power of sunlight by focusing on a naturally occurring combination of lipids that have been strikingly conserved throughout evolution.

Spin Diagnostics: MRI for a quantum simulation Posted: 31 Jul 2014 08:09 AM PDT Recently physicists have executed an MRI-like diagnostic on a crystal of interacting quantum spins. They predict that their method is scalable and may be useful for validating experiments with large ensembles of interacting spins.

Neutron tomography technique reveals phase fractions of crystalline materials in 3-dimensions Posted: 31 Jul 2014 06:51 AM PDT Researchers have developed a novel method, based on energy-selective neutron imaging for visualization of crystalline phase distributions within the bulk of metallic samples.

New system to optimize public lighting power consumption Posted: 31 Jul 2014 06:46 AM PDT Scientists have designed an energy regulation system based on the combination of diverse electromagnetic elements. This system is able to efficiently reduce the luminous flux of lamps by reducing the voltage According to the researchers, this new system is strong and efficient and hardly needs any maintenance. Its size, weight and cost are lower than the systems used today based on power electronics.
