1980s aircraft helps quantum technology take flight
1980s aircraft helps quantum technology take flight 20 October 2014 What does a 1980s experimental aircraft have to do with state-of-the art quantum technology? Lots, as shown by new research from the Quantum Control Laboratory at the University of Sydney, and published in Nature Physics today. Over several years a team of scientists has taken inspiration from aerospace research and development programs to make unusually shaped experimental aircraft fly.

Architectural engineering's Houser leads study on perceptions of LED lighting
UNIVERSITY PARK, Pa. A research team led by Kevin Houser, professor of architectural engineering, has determined that color and whiteness rendition has a profound effect on LED light source preference. The team's findings were published in Lighting Research & Technology in an article titled "Perceptual responses to LED illumination with colour rendering indices of 85 and 97" at: .

New imaging technique could detect acoustically “invisible” cracks
Press release issued: 6 October 2014 The next generation of aircraft could be thinner and lighter thanks to the development of a new imaging technique that could detect damage previously invisible to acoustic imaging systems. The nonlinear acoustic technique developed by researchers from the University of Bristol's Ultrasonics and Non-destructive Testing (NDT) research group is published in the current issue of Physical Review Letters together with an accompanying article in Physics .

Los Alamos conducts important hydrodynamic experiment in Nevada
Los Alamos conducts important hydrodynamic experiment in Nevada
Hydrodynamic experiments such as Leda involve non-nuclear surrogate materials that mimic many of the properties of nuclear materials. "This experiment ultimately enhances confidence in our ability to predictively model and assess weapon performance in the absence of full-scale underground nuclear testing," said Webster.

Bubbling down: Discovery suggests surprising uses for common bubbles
Bubbling down: Discovery suggests surprising uses for common bubbles Posted August 19, 2014; 09:30 a.m. by John Sullivan, Office of Engineering Anyone who has ever had a glass of fizzy soda knows that bubbles can throw tiny particles into the air. But in a finding with wide industrial applications, Princeton researchers have demonstrated that the bursting bubbles push some particles down into the liquid as well.

For stable flight, fruit flies sense every wing beat
Simulated flight without control. The model insect hovers for a brief period before succumbing to pitch instability, which leads to its tumble and fall. In order to stabilize their flight, fruit flies sense the orientation of their bodies every time they beat their wings - one beat about every 4 milliseconds.

Verifying the future of quantum computing
Press release issued: 30 July 2014 Physicists are one step closer to proving the reliability of a quantum computer - a machine which promises to revolutionise the way we trade over the internet and provide new tools to perform powerful simulations. By harnessing the strange laws of quantum mechanics, future quantum computers offer the hope of quickly solving problems that would take even the best supercomputers the lifetime of the universe to solve.

Groundwater is safe in potential N.Y. fracking area
Groundwater is safe in potential N.Y. fracking area
Two Cornell hydrologists have completed a thorough groundwater examination of drinking water in a potential hydraulic fracturing area in New York's Southern Tier. They determined that drinking water in potable wells near conventional natural gas wells in Chenango County is safe to drink and within federal guidelines.

Building up bamboo
Building up bamboo
Bamboo construction has traditionally been rather straightforward: Entire stalks are used to create latticed edifices, or woven in strips to form wall-sized screens. The effect can be stunning, and also practical in parts of the world where bamboo thrives. But there are limitations to building with bamboo.

Fires are major cause of wind farm failure, according to new research
Fires are major cause of wind farm failure, according to new research
Fire is the second leading cause of accidents in wind turbines, after blade failure, according to research out today. Wind farming is one of the leading industries in the renewable energy sector. However, the industry faces a number of challenges, such as opposition by wind farm lobbyists. Today's research suggests that incidents of wind turbines catching fire are a big problem that is not currently being fully reported.

Months before their first words, babies' brains rehearse speech mechanics
Months before their first words, babies’ brains rehearse speech mechanics
University of Washington Infants can tell the difference between sounds of all languages until about 8 months of age when their brains start to focus only on the sounds they hear around them. It's been unclear how this transition occurs, but social interactions and caregivers' use of exaggerated "parentese” style of speech seem to help.

Aviation offers a way forward in biofuels research
Biofuels researchers are increasingly thinking about how the energy market is changing, which challenges them to balance the basic science of new fuels with a more holistic view of the most commercially viable ways to produce them. So when a group of University of Wisconsin-Madison researchers began looking at how to make jet fuel from biomass, they also strived to create a "techno-economic" framework that would illuminate the entire biofuels field.

Greater potential for low-cost solar power plants
Greater potential for low-cost solar power plants
New analysis of large-scale 'concentrating solar power' plants suggests they could meet 70-80% of electricity demand if they are linked together. In a new study published Climate Change, researchers from the Grantham Institute at Imperial College London, Stellenbosch University , and the International Institute for Applied Systems Analysis (IIASA) have calculated for the first time that connecting 'concentrating solar power' (CSP) plants could supply a significant amount of current electricity demand, alleviating concerns over the reliability and intermittency of renewable power.

Spiders know the meaning of web music
Spider silk transmits vibrations across a wide range of frequencies so that, when plucked like a guitar string, its sound carries information about prey, mates, and even the structural integrity of a web. The discovery was made by researchers from the Universities of Oxford, Strathclyde, and Sheffield who fired bullets and lasers at spider silk to study how it vibrates.

Stem cells take initial step toward development in the lab
Stem cells take initial step toward development in the lab
CHAMPAIGN, Ill. The gap between stem cell research and regenerative medicine just became a lot narrower, thanks to a new technique that coaxes stem cells, with potential to become any tissue type, to take the first step to specialization. It is the first time this critical step has been demonstrated in a laboratory.
