How the body fights against viruses
Scientists of the Max F. Perutz Laboratories of the University of Vienna and the Medical University of Scientists of the Max F. Perutz Laboratories of the University of Vienna and the Medical University of Vienna, together with colleagues of the ETH Zurich, have shown how double stranded RNA is prevented from entering the nucleus of a cell. During the response against viral infection, the protein ADAR1 moves from the cell nucleus into the surrounding cytoplasm.

Study: People pay more attention to the upper half of field of vision
A new study from North Carolina State University and the University of Toronto finds that people pay more attention to the upper half of their field of vision -- a finding which could have ramifications for traffic signs to software interface design.

UV-radiation data to help ecological research
Researchers at the Helmholtz Centre for Environmental Research have processed existing data on global UV-B radiation in such a way that scientists can use them to find answers to many ecological questions. According to the paper published in Methods in Ecology and Evolution, an online journal of the British Ecological Society, this data set allows drawing new conclusions about the global distribution of animal and plant species.

New design for mobile phone masts could cut carbon emissions
A breakthrough in the design of signal amplifiers for mobile phone masts could deliver a massive 200MW cut in the load on UK power stations, reducing CO2 emissions by around 0.5 million tons a year. Funded by the Engineering and Physical Sciences Research Council, the universities of Bristol and Cardiff have designed an amplifier that works at 50 percent efficiency compared with the 30 percent now typically achieved.

Inserm and the Institut Pasteur identify a new variant of Ebola virus in Guinea
In an article which appeared in The New England journal of Medicine on April 16, researchers from Inserm and the Institut Pasteur have published their initial findings on the characteristics of the Ebola virus discovered in Guinea. Initial virological investigations enabled them to identify Zaire ebolavirus as the pathogen responsible for this epidemic.

Like a hall of mirrors, nanostructures trap photons inside ultrathin solar cells
'We want to make sure light spends more quality time inside a solar cell,' said Mark Brongersma, a professor of materials science and engineering at Stanford. He and two co-authors surveyed 109 scientific papers involving ways to maximize the collisions between photons and electrons in the thinnest possible layer of photovoltaic material. The goal is to reveal trends and best practices that will help lower solar energy costs.

Minnesota projects offer hope and practical help to communities facing more extreme storms
A 10-year-old program in the Midwest and New England works with communities to prepare for more extreme storms. The program is important because results are specific to each local community. It helps communities plan for the extreme storms that already are occurring more frequently, and shows how to manage the uncertainty of long-term projections. Portions of existing drainage systems are already undersized, and portions should be adequate even for pessimistic future conditions.

RNA shows potential as boiling-resistant anionic polymer material for nanoarchitectures
Nanotechnology researchers at the University of Kentucky have discovered new methods to build boiling-resistant nanostructures and arrays using a new RNA triangle scaffold. These new RNA nanoarchitechtures can be used to form arrays with a controllable repeat number of the scaffold, resembling monomer units in a polymerization reaction. Their enhanced structural stability and controllability at the nano scale offer key advantages over traditional chemical polymers.

Scientists discover a new way to enhance nerve growth following injury
New research published today out of the University of Calgary's Hotchkiss Brain Institute uncovers a mechanism to promote growth in damaged nerve cells as a means to restore connections after injury. Dr. Doug Zochodne and his team have discovered a key molecule that directly regulates nerve cell growth in the damaged nervous system.

Stroke treatment, outcomes improve at hospitals participating in UCLA-led initiative
A study demonstrated that hospitals participating in a national quality-improvement program have markedly increased the speed with which they treat stroke patients with a clot-busting drug. This speedier treatment was accompanied by reduced mortality, fewer treatment complications and a greater likelihood that patients would go home after leaving the hospital instead of being referred to a skilled nursing facility.

Cougars' diverse diet helped them survive the Pleistocene mass extinction
Cougars may have survived the mass extinction that took place about 12,000 years ago because they were not particular about what they ate, unlike their more finicky cousins the saber-tooth cat and American lion who perished, according a new analysis of the microscopic wear marks on the teeth of fossil cougars, saber-tooth cats and American lions.

International team sequences rainbow trout genome
Using fish bred at Washington State University, an international team of researchers has mapped the genetic profile of the rainbow trout, a versatile salmonid whose relatively recent genetic history opens a window into how vertebrates evolve. The 30-person team, led by Yann Guiguen of the French National Institute for Agricultural Research, reports its findings this week in Nature Communications.

High-performance, low-cost ultracapacitors built with graphene and carbon nanotubes
By combining the powers of two single-atom-thick carbon structures, researchers at the George Washington University's Micro-propulsion and Nanotechnology Laboratory have created a new ultracapacitor that is both high performance and low cost. The device, described in the Journal of Applied Physics, capitalizes on the synergy brought by mixing graphene flakes with single-walled carbon nanotubes, two carbon nanostructures with complementary properties.

Getting at the root of the mountain pine beetle's rapid habitat expansion and forest
The mountain pine beetle has wreaked havoc in North America, across forests from the American Southwest to British Columbia and Alberta, with the potential to spread all the way to the Atlantic coast. Using a newly sequenced beetle genome, authors Janes, et.al. examined how the pine beetle could undergo such rapid habitat range expansion.

Study examines effectiveness of medications for treating epileptic seizures in children
