Between 10 and 20 percent of all cases of epilepsy result from severe head injury, but a new drug promises to prevent post-traumatic seizures and may forestall further brain damage caused by seizures in those who already have epilepsy. A team of researchers from the University of California, Berkeley, Ben-Gurion University in Israel and Charité-University Medicine in Germany reports in the current issue of the journal Annals of Neurology that a commonly used hypertension drug prevents a majority of cases of post-traumatic epilepsy in a rodent model of the disease. If ...

Many studies have shown that exposure to environmental enrichment can induce neurogenesis of the hippocampal region, thus improving learning and memory. Previous studies have demonstrated that doublecortin-positive immature neurons exist predominantly in the superficial layer of the cerebral cortex of adult mammals such as guinea pigs, and these neurons exhibit very weak properties of self-proliferation during adulthood under physiological conditions. Whether environmental enrichment has an impact on the proliferation and maturation of these immature neurons in the prefrontal ...

In the quest to make sun power more competitive, researchers are designing ultrathin solar cells that cut material costs. At the same time they're keeping these thin cells efficient by sculpting their surfaces with photovoltaic nanostructures that behave like a molecular hall of mirrors. "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 and co-author of a review article in Nature Materials. Brongersma and two Stanford colleagues -- associate professor of materials ...

Theoretical physicists are currently exploring the dynamics of a very unusual kind of device called a SQUID. This Superconducting Quantum Interference Device is a highly sensitive magnetometer used to measure extremely subtle magnetic fields. It is made of two thin regions of insulating material that separate two superconductors – referred to as Josephson junctions – placed in parallel into a ring of superconducting material. In a study published in EPJ B, US scientists have focused on finding an analytical approximation to the theoretical equations that govern the dynamics ...

PITTSBURGH—Spreadsheets may have been the original killer app for personal computers, but data tables don't play to the strengths of multi-touch devices such as tablets. So researchers at Carnegie Mellon University have developed a visualization approach that allows people to explore complex data with their fingers. Called Kinetica, this proof-of-concept system for the Apple iPad converts tabular data, such as Excel spreadsheets, so that data points appear as colored spheres on the touchscreen. People can directly manipulate this data, using natural gestures to sort, ...

PHILADELPHIA (April 22, 2014) – Older parents are more likely to have a child who develops an autism spectrum disorder (ASD) than are younger parents. A recent study from researchers from the Drexel University School of Public Health in Philadelphia and Karolinska Institute in Sweden provides more insight into how the risk associated with parental age varies between mothers' and fathers' ages, and found that the risk of having a child with both ASD and intellectual disability is larger for older parents. In the study, published in the February 2014 issue of the International ...

Ions are an essential tool in chip manufacturing, but these electrically charged atoms can also be used to produce nano-sieves with homogeneously distributed pores. A particularly large number of electrons, however, must be removed from the atoms for this purpose. Such highly charged ions either lose a surprisingly large amount of energy or almost no energy at all as they pass through a membrane that measures merely one nanometer in thickness. Researchers from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and Vienna University of Technology (TU Wien) report in the scientific ...

Visit a typical gym and you will encounter a highly standardised notion of what the human body should look like and how much it should weigh. This strictly controlled body ideal is spread across the world by large actors in the fitness industry. A new study explores how the fitness industry in many ways resembles that of fast food. One of the authors is from the University of Gothenburg. McDonaldisation of the gym culture is the theme of an article published in Sports, Education and Society, where Thomas Johansson, professor at the University of Gothenburg, together ...

CINCINNATI—Inflammatory Bowel Disease (IBD), a group of chronic inflammatory disorders of the intestine that result in painful and debilitating complications, affects over 1.4 million people in the U.S., and while there are treatments to reduce inflammation for patients, there is no cure. Now, Cincinnati Cancer Center and University of Cincinnati (UC) Cancer Institute researcher Susan Waltz, PhD, and scientists in her lab have done what is believed to be the first direct genetic study to document the important function for the Ron receptor, a cell surface protein often ...

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 tonnes a year. Funded by the Engineering and Physical Sciences Research Council (EPSRC), the Universities of Bristol and Cardiff have designed an amplifier that works at 50 per cent efficiency compared with the 30 per cent now typically achieved. Currently, a 40W transmitter in a phone mast's base station* requires just over 130W of power to amplify signals and send them wirelessly ...

To address the fact that many of us are on the go and pressed for time, app developers have devised speed-reading software that eliminates the time we supposedly waste by moving our eyes as we read. But don't throw away your books, papers, and e-readers just yet — research suggests that the eye movements we make during reading actually play a critical role in our ability to understand what we've just read. The research is published in Psychological Science, a journal of the Association for Psychological Science. "Our findings show that eye movements are a crucial part ...

Many research projects study the effects of temperature and precipitation on the global distribution of plant and animal species. However, an important component of climate research, the UV-B radiation, is often neglected. The landscape ecologists from UFZ in collaboration with their colleagues from the Universities in Olomouc (Czechia), Halle and Lüneburg have processed UV-B data from the U.S. NASA space agency in such a way that they can be used to study the influence of UV-B radiation on organisms. The basic input data were provided by a NASA satellite that regularly, ...

Spectral properties optimization is an important issue for developing schemes to resolve flow fields that are characterized by a wide range of length scales such as turbulent flows and aero acoustic phenomena. The work finished by Dr SUN Zhensheng and his ground provided a novel approach to optimize the dissipation and dispersion properties of a family of tri-diagonal compact schemes. The corresponding paper entitled "A high-resolution, hybrid compact-WENO scheme with minimized dispersion and controllable dissipation" was published in Sci China-Phys Mech Astron, 2014 Vol. ...

COLUMBIA, Mo. – The term "tween" denotes a child who is between the ages of 8 and 12 and is used to describe a preadolescent who is "in between" being a child and a teen. This demographic watches more television than any other age group and is considered to be a very lucrative market. Tween television programming consists of two genres: "teen scene" (geared toward girls) and "action-adventure" (geared toward boys). Researchers at the University of Missouri found that these programs could lead tweens to limit their views of their potential roles in society just as they begin ...

Los Angeles, CA (April 22, 2014) Labor trafficking – or recruiting a person for labor through force, fraud, or coercion for involuntary servitude, debt bondage, or even slavery – has been a difficult problem to track among undocumented migrant workers. With unique access to a "hidden population" from one of America's largest Spanish-speaking immigrant destinations, a recent study finds that more than 30% of undocumented migrant laborers in this area are victims of labor trafficking and 55% are victims of other labor abuses. In this study, published in the May issue of ...

A new prediction tool can help doctors better identify patients who are at highest risk for respiratory failure after surgery and therefore prevent the often deadly condition, suggest data from a large multi-center study published in the May issue of Anesthesiology. Affecting nearly 200,000 Americans a year, acute respiratory distress syndrome (ARDS) is a sudden failure of the lungs caused by a number of issues ranging from smoke inhalation to pneumonia or blood infection. High-risk patients can develop ARDS after surgery. ARDS is difficult to treat once it develops and ...

Recent projects in two Minnesota cities demonstrate how communities can protect themselves from worsening storms. These projects continue a ten year program in New England and the Midwest providing practical and affordable plans tailored to local conditions. "Our goal is to help communities begin the steps to protect themselves," said program co-leader Latham Stack, of Syntectic International, Portland, OR. "It's important because storms have already worsened. We help communities move beyond feeling paralyzed from the lack of local information and the sense that the problem ...

(Lebanon, NH, 4/22/14). Dartmouth researchers have found that the anxiety experienced with a false-positive mammogram is temporary and does not negatively impact a woman's overall well-being. Their findings are reported in "Consequences of False-Positive Screening Mammograms," which was published online in the April 21, 2014 JAMA Internal Medicine Anywhere from 40 to 60 percent of women who undergo routine screening mammography during a ten-year period will experience a false-positive mammogram. Such mammograms require additional testing, sometimes involving a biopsy, ...

Bariatric surgery has positive effects not only on weight loss but also on diabetes and heart disease. Researchers at the Sahlgrenska Academy and University of Cincinnati have shown that the health benefits are not caused by a reduction in the stomach size but by increased levels of bile acids in the blood. These findings, reported in Nature, indicate that bile acids could be a new target for treating obesity and diabetes. Previous research from the Sahlgrenska Academy has demonstrated that obesity surgery is the only effective treatment for obesity and obesity-related ...

Cambridge, MA, April 22, 2014 – Researchers from NeuroPhage Pharmaceuticals, Inc. have engineered a series of molecules with the potential to treat most neurodegenerative diseases that are characterized by misfolded proteins, such as Alzheimer's, Parkinson's and Huntington's diseases. These molecules are based on what the Company calls a general amyloid interaction motif, or GAIM, which recognizes a characteristic common to many toxic, misfolded proteins, not just one type of misfolded protein. This approach provides NeuroPhage with an array of therapeutic targets, so that ...

Researchers at the University of Toronto say a sleep disorder that causes people to act out their dreams is the best current predictor of brain diseases like Parkinson's and Alzheimer's. "Rapid-eye-movement sleep behaviour disorder (RBD) is not just a precursor but also a critical warning sign of neurodegeneration that can lead to brain disease," says associate professor and lead author Dr. John Peever. In fact, as many as 80 to 90 per cent of people with RBD will develop a brain disease." As the name suggests, the disturbance occurs during the rapid-eye-movement (REM) ...

Mysteries of one of the most fascinating nearby planetary systems now have been solved, report authors of a scientific paper to be published by the journal Monthly Notices of the Royal Astronomical Society in its early online edition on 22 April 2014. The study, which presents the first viable model for the planetary system orbiting one the first stars discovered to have planets -- the star named 55 Cancri -- was led by Penn State University graduate student Benjamin Nelson in collaboration with faculty at the Center for Exoplanets and Habitable Worlds at Penn State and ...

HOUSTON – (April 22, 2014) – Most people think the development of the heart only happens in the womb, however the days and weeks following birth are full of cellular changes that play a role in the structure and function of the heart. Using mouse models, researchers at Baylor College of Medicine have now been able to categorize the alternative splicing (the process in which genes code proteins, determining their role) that takes place during these changes and what mechanisms they affect. The findings, which appear in Nature Communications, also helped to identify a ...
