Geoengineering our climate is not a 'quick fix' Posted: 25 Nov 2014 05:57 PM PST The deliberate, large-scale intervention in the Earth's climate system is not a "quick fix" for global warming, according to new findings.

Researchers develop efficient method to produce nanoporous metals Posted: 25 Nov 2014 12:47 PM PST Nanoporous metals -- foam-like materials that have some degree of air vacuum in their structure -- have a wide range of applications because of their superior qualities.

Converting Human-Generated Waste Into Fuel in Space Posted: 25 Nov 2014 12:46 PM PST Who would've known human waste could be used to propel spacecraft from the moon back to Earth? Researchers responded to the call from NASA and came up with a process to convert waste to methane and propel spacecraft to Earth.

Entrepreneurs to venture capitalists: Don’t be a Scrooge Posted: 25 Nov 2014 12:39 PM PST A recently published study of more than 550 decisions and responses from 144 experienced entrepreneurs reveals that "knowledge of explicit ethical or unethical behavior (by venture capitalists) profoundly shapes the entrepreneurs' willingness to partner."

Physicists bind single-atom sheets with the same force geckos use to climb walls Posted: 25 Nov 2014 10:19 AM PST The approach is to design synergistic materials by combining two single-atom thick sheets, for example, that act as a photovoltaic cell as well as a light-emitting diode, converting energy between electricity and radiation.

Physicists predict fano resonance in lead-free relaxors: Discovery advances knowledge of poorly understood materials Posted: 25 Nov 2014 09:48 AM PST Scientists predicts that a phenomenon known in physics as Fano resonance can exist in materials that are used in electronic devices. The discovery advances the fundamental understanding of ferroelectric relaxors, which were discovered in the early 1960s but whose properties are still poorly understood.

E-health records used to search for hidden drug benefits Posted: 25 Nov 2014 08:18 AM PST With research and development costs for many drugs reaching well into the billions, pharmaceutical companies want more than ever to determine whether their drugs already at market have any hidden therapeutic benefits that could warrant putting additional indications on the label and increase production.

Blu-ray disc can be used to improve solar cell performance Posted: 25 Nov 2014 08:18 AM PST Who knew about Blu-ray discs? One of the best ways to store high-definition movies and television shows because of their high-density data storage, Blu-ray discs also improve the performance of solar cells, according to a new study. Researchers have discovered that the pattern of information written on a Blu-ray disc -- and it doesn't matter if it's Jackie Chan's 'Supercop' or the cartoon 'Family Guy' -- works very well for improving light absorption across the solar spectrum.

Incomes fall as stressed economy struggles Posted: 25 Nov 2014 07:21 AM PST Australian average incomes are falling with the country's population growth 'masking underlying economic weakness', according to an economist.

Feeling -- not being -- wealthy drives opposition to wealth redistribution Posted: 25 Nov 2014 07:21 AM PST People's views on income inequality and wealth distribution may have little to do with how much money they have in the bank and a lot to do with how wealthy they feel in comparison to their friends and neighbors, according to new findings.

Barriers to public health data-sharing; life-saving solutions Posted: 25 Nov 2014 07:21 AM PST Barriers to the sharing of public health data hamper decision-making efforts on local, national and global levels, and stymie attempts to contain emerging global health threats, an international team of researchers has announced.

New plastic that disappears when you want it to Posted: 25 Nov 2014 07:17 AM PST Plastic populates our world through everything from electronics to packaging and vehicles. Once discarded, it resides almost permanently in landfills and oceans. A new discovery holds scientific promise that could lead to a new type of plastic that can be broken down when exposed to a specific type of light and is reduced back to molecules, which could then be used to create new plastic.

Breakthrough in flexible electronics enabled by inorganic-based laser lift-off Posted: 25 Nov 2014 06:54 AM PST Engineers have developed an easier methodology to make high performance flexible electronics by using the Inorganic-based Laser Lift-off (ILLO), which enables nanoscale processes for high density flexible devices and high temperature processes that were previously difficult to achieve on plastic substrates.

Researchers find way to turn sawdust into gasoline Posted: 25 Nov 2014 06:11 AM PST Researchers have successfully converted sawdust into building blocks for gasoline. Using a new chemical process, they were able to convert the cellulose in sawdust into hydrocarbon chains. These hydrocarbons can be used as an additive in gasoline, or as a component in plastics.

Scientists could save thousands with student's DIY microscope Posted: 25 Nov 2014 04:48 AM PST Expensive tests for measuring everything from sperm motility to cancer diagnosis have just been made hundreds of thousands of dollars cheaper by a Ph.D. student from England who hacked his own microscope.

New device may ease mammography discomfort Posted: 25 Nov 2014 04:48 AM PST A new device that may result in more comfortable mammography for women has been created by researchers. According to a new study, standardizing the pressure applied in mammography would reduce pain associated with breast compression without sacrificing image quality.

Bitcoin, virtual money: User's identity can be revealed much easier than thought Posted: 25 Nov 2014 04:47 AM PST Bitcoin is the new money: minted and exchanged on the Internet. Faster and cheaper than a bank, the service is attracting attention from all over the world. But a big question remains: are the transactions really anonymous? Several research groups worldwide have shown that it is possible to find out which transactions belong together, even if the client uses different pseudonyms. However it was not clear if it is also possible to reveal the IP address behind each transaction. This has changed: researchers have now demonstrated how this is feasible with only a few computers and about €1500.

Schistosomas: Tropical parasite uses swim stroke not shared by any other creature Posted: 25 Nov 2014 04:46 AM PST For many bacteria and parasites looking to get a load of the fresh nutritional bounty inside your body, the skin is the first and most important gatekeeper. Schistosomas, however, and burrow right on through. These waterborne blood flukes, responsible for 200 million total worldwide cases of Schistosomiasis, are driven by the powerful thrusts of their unique forked tails and chewing enzymes. The parasite's swimming patterns are crucial for its human-seeking chemotactic activity - and are the focus of researchers who ultimately seek to break the chain of infection.

Fluid dynamics explain what happens when dogs drink water Posted: 25 Nov 2014 04:46 AM PST If you've ever watched a dog drink water, you know that it can be a sloshy, spilly, splashy affair -- in other words, adorable. Behind all of the happy, wet messes, however, lies the mechanical logic of carnivorous compensation -- dogs splash when they drink because they have the cheeks of a predatory quadruped. By studying the drinking habits of various dog breeds and sizes, researchers have recently identified and modeled the fluid dynamics at play when dogs drink water.

Espresso in space: You knew it was only a matter of time before espresso made its way to the International Space Station, right? Posted: 25 Nov 2014 04:46 AM PST Espresso-loving astronauts, rejoice! You may soon be able to enjoy your beloved beverage in space, thanks to a new cup designed specifically to defy the low-gravity environments encountered aboard the International Space Station (ISS).

Small modifications to tractor-trailers could save billions of gallons of gasoline each year Posted: 25 Nov 2014 04:46 AM PST Each year, the more than 2 million tractor-trailer trucks that cruise America's highways consume about 36 billion gallons of diesel fuel, representing more than 10 percent of the nation's entire petroleum use. That fuel consumption could be reduced by billions of gallons a year through the use of drag-reducing devices on trucks, according to new studies.

Climate control in termite mounds Posted: 25 Nov 2014 04:46 AM PST Researchers have found that fluctuations in outside temperature create convection currents within termite mounds to ventilate the living space.

The physics of artist Jackson Pollock Posted: 24 Nov 2014 11:33 AM PST Jackson Pollock, one of the greatest American artists of the 20th century, revolutionized abstract expressionist painting in the mid-20th century with his unique "drip" technique -- masterpieces of densely tangled lines of color that Pollock often created from thinned household enamel paints. Now, an experimental technique developed by fluid dynamicists may help reveal exactly how Pollock produced certain features in his paintings.
