Today, technicians in Minnesota will begin to position the first block of a detector that will be part of the largest, most advanced neutrino experiment in North America.
The NuMI Off-Axis Neutrino Appearance experiment – NOvA for short – will study the properties of neutrinos, such as their masses, and investigate whether they helped give matter an edge over antimatter after both were created in equal amounts in the big bang. The experiment is on track to begin taking data in 2013.
Every day we observe systems thermalizing: Ice cubes in a pot of hot water will melt and will never remain stable. The molecules of the ice and the molecules of the water will reach thermal equilibrium, ending up at the same temperature. Well-ordered ice crystals turn into a disordered liquid.
Experiments at the Vienna Center for Quantum Science and Technology (VCQ) at the Vienna University of Technology have shown that in the quantum world the transition to thermal equilibrium is more interesting and more complicated than assumed so far.
TORONTO, Sept. 6, 2012 – Imagine that the players on your favourite football team were smaller than their opponents, and had to play without helmets or pads. Left defenseless, they would become easy prey for other teams. Similarly, changes in Canadian lake water chemistry have left small water organisms vulnerable to their predators, which may pose a serious environmental threat, according to a new study.
DURHAM, N.C. -- Destruction of coastal habitats may release as much as 1 billion tons of carbon emissions into the atmosphere each year, 10 times higher than previously reported, according to a new Duke led study.
Deforestation can have a significant effect on tropical rainfall, new research confirms. The findings have potentially devastating impacts for people living in and near the Amazon and Congo forests.
A team from the University of Leeds and the NERC Centre for Ecology & Hydrology found that for the majority of the Earth's tropical land surface, air passing over extensive forests produces at least twice as much rain as air passing over little vegetation. In some cases these forests increased rainfall thousands of kilometres away.
The United Kingdom is preparing to convert the London 2012 Olympics anti-doping center, which conducted more than 6,000 drug tests on athletes during the Olympic and Paralympic Games, into a facility that could help revolutionize 21st century health care. That new facility — the world's first national "phenome center" — is the topic of a story in the current edition of Chemical & Engineering News (C&EN). C&EN is the weekly newsmagazine of the American Chemical Society, the world's largest scientific society.
The Canadian government's plans to discontinue in 2013 a unique environmental research project that has yielded insights into water pollution, climate change and other topics for almost 40 years would be a "huge loss not only to science but to the scientific heritage of humanity." That's the focus of a viewpoint article in ACS' journal Environmental Science & Technology.
In a Policy Forum article in this week's PLOS Medicine Madhukar Pai from McGill University, Canada and colleagues discuss a framework for how point-of-care testing can be applied to infectious diseases in low- and middle-income countries. The authors note that a range of barriers exist to prevent successful use of point-of-care testing and that the availability alone of rapid or simple tests does not automatically ensure their adoption or scale-up.
A University of Central Florida research team has created the world's shortest laser pulse and in the process may have given scientists a new tool to watch quantum mechanics in action – something that has been hidden from view until now.
UCF Professor Zenghu Chang from the Department of Physics and the College of Optics and Photonics, led the effort that generated a 67-attosecond pulse of extreme ultraviolet light. The results of his research are published online under Early Posting in the journal Optics Letters.
An archaeologist from the University of Sheffield has revealed the origin and trading routes of razor-sharp stone tools 4,200 years ago in Syria.
Ancient sites and cultural heritage are under threat in Syria due to the current conflict. An interdisciplinary research team hopes this new discovery, which has major implications for understanding the world's first empire, will help to highlight the importance of protecting Syria's heritage.
HOUSTON – (Sept. 4, 2012) – Like tiny ships finding port in a storm, carbon atoms dock with the greater island of graphene in a predictable manner. But until recent research by scientists at Rice University, nobody had the tools to make that kind of prediction.
Might it one day be possible to transmit electricity from an offshore wind turbine to land-based users without any loss of current? Materials known as "high temperature" superconductors (even though they must be maintained at -140°C!), which can conduct electricity without any losses, were supposed to make this dream a reality. But over the past twenty-five years, scientists have not been able to make any progress in this area. Research being done in EPFL's Laboratory for Quantum Magnetism (LQM) could change that.
A new model allows researchers at UNESCO-IHE, Delft University of Technology and Deltares to much more accurately predict coastline erosion due to rising sea levels. It would appear that the effects of coastline erosion as a result of rising sea-level rise in the vicinity of inlets, such as river estuaries, have until now been dramatically underestimated. The scientists have published their research in the online edition of Nature Climate Change on Sept. 2, 2012.

A new fungal species, called 'Hebelomagriseopruinatum', has now officially been included in the list of species. The fungus, whose name can be translated into 'the grey-dewy tear leaf', was discovered on Zealand in Denmark during a mushroom-hunting tour headed by postdoc Jacob Heilman-Clausen from the University of Copenhagen.
During a mushroom-hunting excursion in 2009, postdoc Jacob Heilman-Clausen from the Center for Macroecology, Evolution and Climate at the Department of Biology, University of Copenhagen, was handed a very interesting looking fungus.
Vienna, Austria: The prevalence of smoking in Christchurch, New Zealand, increased following the 2010 earthquake, according to a new study.
The results of the study will be presented today (4 September 2012) at the European Respiratory Society's Annual Congress in Vienna.
The 7.1-magnitude Christchurch earthquake, and subsequent aftershocks, have caused a huge amount of damage and dramatically changed the social, working and living conditions for residents in the city.
