Amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease, and frontotemporal dementia (FTD) are devastating neurodegenerative diseases with no effective treatment. Researchers are beginning to recognize ALS and FTD as part of a spectrum disorder with overlapping symptoms. Now investigators reporting online February 12 in the Cell Press journal Neuron have discovered an abnormal protein that first forms as a result of genetic abnormalities and later builds up in the brains of many patients with either disease. "In identifying the novel protein that abnormally accumulates ...

Researchers have given rats the ability to "touch" infrared light, normally invisible to them, by fitting them with an infrared detector wired to microscopic electrodes implanted in the part of the mammalian brain that processes tactile information. The achievement represents the first time a brain-machine interface has augmented a sense in adult animals, said Duke University neurobiologist Miguel Nicolelis, who led the research team. The experiment also demonstrated for the first time that a novel sensory input could be processed by a cortical region specialized in ...

A group of researchers have designed a new fuzzy ontology-based system to help people in disagreement reach consensus. This system, which acts as a virtual moderator, is a step forward in the field on Artificial Intelligence. This tool can be useful in making everyday decisions –such as choosing a wine in a restaurant–, but it can also be helpful in complex negotiations between countries fighting for their interests in the European Union framework. Fuzzy ontologies represent the relationships among basic concepts. This new system uses ontology to help in the decision-making ...

Amsterdam, NL, 12 February 2013 – Millions of people worldwide are regularly exposed to arsenic through drinking water and eating rice grown in soil and water containing high amounts of arsenic. Long-term exposure can lead to the development of different types of cancer as well as serious cardiovascular, neurological, and other health problems. Scientists have now identified aromatic rice from Bangladesh that has far lower arsenic concentrations than found in non-aromatic rice. The other important benefit is that it contains higher amounts of selenium and zinc. The discovery ...

WASHINGTON – Even very young children understand that adults don't always know best. When it comes to helping, 3-year-olds may ignore an adult's specific request for an unhelpful item and go out of their way to bring something more useful, according to new research published by the American Psychological Association. Youngsters may also attempt to warn adults who are doing something counterproductive, such as reaching for an empty box of crayons to draw a picture or putting on a wet sweatshirt when they say they are cold, according to the article published online in ...

Researchers at Johannes Gutenberg University Mainz (JGU) have confirmed the original model of the molecular structure of water and have thus made it possible to resolve a long-standing scientific controversy about the structure of liquid water. The tetrahedral model was first postulated nearly 100 years ago and it assumes that every water molecule forms a so-called hydrogen bond with four adjacent molecules. This concept was almost toppled in 2004 when an international research group announced that it had experimentally established that water molecules form bonds only with ...

Bethesda, MD—Notorious among athletes and trainers as career killers, Achilles tendon injuries are among the most devastating. Now, by carbon testing tissues exposed to nuclear fallout in post WWII tests, scientists have learned why: Like our teeth and the lenses in our eyes, the Achilles tendon is a tissue that does not repair itself. This discovery was published online in The FASEB Journal. "Tendon injury is a very common disease, which hinders many people from enjoying the numerous benefits of sports and recreational activities," said Katja Heinemeier, Ph.D., a researcher ...

This press release is available in French. Montreal, February 12, 2013 – If you started piano lessons in grade one, or played the recorder in kindergarten, thank your parents and teachers. Those lessons you dreaded – or loved – helped develop your brain. The younger you started music lessons, the stronger the connections in your brain. A study published last month in the Journal of Neuroscience suggests that musical training before the age of seven has a significant effect on the development of the brain, showing that those who began early had stronger connections ...

Philadelphia, PA, February 12, 2013 – Scopolamine is an anticholinergic drug with many uses. For example, it prevents nausea, vomiting, and motion sickness. However, scopolamine is re-emerging as an antidepressant, with recent studies showing that scopolamine can rapidly improve mood in depressed patients. In addition, in a new study published in Biological Psychiatry this month by Dr. Moriel Zelikowsky and colleagues at the University of California, Los Angeles, it may also be a possible treatment for anxiety disorders. Exposure therapy, where the key goal is the ...

A significant percentage of the costs of wind energy is due to wind turbine failures, as components are weakened under turbulent air flow conditions and need to be replaced. The challenge for the team was to find a method for detecting fatigue in the wind turbines' parts without having to remove each of the components and while the turbine is in operation. Until now, standard methods have relied on so-called spectral analysis, which looks at the different frequency response. But these measurements are distorted by the turbulent working conditions. As a result, these ...

The Photovoltaics-Laboratory (PV-Lab) of EPFL's Insitute of Microengineering (IMT), founded in 1984 by Prof. Arvind Shah and now headed by Prof. Christophe Ballif, is well known as a pioneer in the development of thin-film silicon solar cells, and as a precursor in the use of microcrystalline silicon as a photoactive material in thin-film silicon photovoltaic (TF-Si PV) devices. A remarkable step was achieved by the team led by Dr. Fanny Meillaud and Dr. Matthieu Despeisse with a new world record efficiency of 10.7% for a single-junction microcrystalline silicon solar cell, ...

New Rochelle, NY, February 12, 2013—About 16,000 women on active duty in the U.S. military give birth each year. Most return to service after 6 weeks and can be deployed after 4 months. The potential for an increased risk of depression among new mothers who deploy and are exposed to combat experience is presented in a study published in Journal of Women's Health, a peer-reviewed publication from Mary Ann Liebert, Inc., publishers. The article is available free on the Journal of Women's Health website at http://www.liebertpub.com/jwh. Stacie Nguyen, MPH and coauthors from ...

OAK BROOK, Ill. – February 12, 2013 – A new study from researchers at the Hospital of the University of Pennsylvania reports that endoluminal (endoscopic) therapies, combining resection and ablation techniques, for patients with Barrett's esophagus and high-grade dysplasia or early mucosal cancer have a high success rate, with durable results and a low risk of complications. The researchers noted that endoscopic surveillance after successful eradication is required. The study appears in the February issue of GIE: Gastrointestinal Endoscopy, the monthly peer-reviewed scientific ...

This press release is available in Spanish. A study led by researchers of the Spanish National Research Council and the University of the Balearic Islands asserts that crew rotation and passengers connections systematically spread flight delays due to a domino effect. The work, that proposes a new methodology to assess the degree of air traffic congestion, is published on the latest issue of Scientific Reports. The study, based on data collected by the Federal Aviation Administration of the United States, provides a tool to evaluate airlines planning and confirms that ...

Researchers at USC have developed a new lithium-ion battery design that uses porous silicon nanoparticles in place of the traditional graphite anodes to provide superior performance. The new batteries—which could be used in anything from cell phones to hybrid cars—hold three times as much energy as comparable graphite-based designs and recharge within 10 minutes. The design, currently under a provisional patent, could be commercially available within two to three years. "It's an exciting research. It opens the door for the design of the next generation lithium-ion batteries," ...

Researchers have developed a model that will, hopefully, help companies develop innovative products that people actually want to use. The model is a first step towards capturing the behavior of both companies and consumers, so that we end up with more iPods and fewer Edsels. This concept may sound obvious, but companies have difficulty grasping it. Companies constantly try to develop new products and services that capture market share. We knew that. Consumers constantly try to evaluate recent innovations to determine whether they're useful, and how much they'd be willing ...

New Rochelle, NY, February 12, 2013—About 1 in 150 children are affected by an autism spectrum disorder (ASD), a group of neurodevelopmental disorders characterized by difficulty with language, communication, and social interaction. A critical review of several published studies evaluating the potential for therapy or assistance dogs to help children with ASD overcome some of these challenges is published in The Journal of Alternative and Complementary Medicine, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available free on the Journal ...

Irvine, Calif., Feb. 12, 2013 – Already strained by water scarcity and political tensions, the arid Middle East along the Tigris and Euphrates rivers is losing critical water reserves at a rapid pace, from Turkey upstream to Syria, Iran and Iraq below. Unable to conduct measurements on the ground in the politically unstable region, UC Irvine scientists and colleagues used data from space to uncover the extent of the problem. They took measurements from NASA's Gravity Recovery and Climate Experiment satellites, and found that between 2003 and 2010, the four nations lost ...

Troy, N.Y. – A new study from engineers at Rensselaer Polytechnic Institute and the University of California, Berkeley, pairs light and genetics to give researchers a powerful new tool for manipulating cells. Results of the study, published in the journal Nature Methods, show how blue light can be used as a switch to prompt targeted proteins to accumulate into large clusters. This process of clustering, or oligomerization, is commonly employed by nature to turn on or turn off specific signaling pathways used in cells' complex system of communications. The new study details ...

More and more opioids are being prescribed for pain relief in Germany. This is the conclusion arrived at by Ingrid Schubert, Peter Ihle, and Rainer Sabatowski, whose study of a sample of inhabitants of the state of Hesse with health insurance from a large statutory provider is published in the latest issue of Deutsches Ärzteblatt International (Dtsch Arztebl Int 2013; 110(4): 45-51). Behind this study lies the intention to improve pain treatment with opioids, particularly for patients with cancer. Prescribing too little results in inadequate alleviation of pain, while ...

SHREWSBURY, MA -- A study published today in the Journal of Applied Physiology, Nutrition, and Metabolism presented compelling data showing the consumption of both high fructose corn syrup (HFCS) and sucrose (table sugar) at levels consistent with average daily consumption do not increase liver fat in humans, a leading cause of non-alcoholic fatty liver disease (NAFLD). The findings also add to an already well-established body of science that high fructose corn syrup and table sugar are metabolically equivalent. Increased fat levels in the liver and muscle tissue have ...

When is it time for parents to back away? A new study shows that college students with overcontrolling parents are more likely to be depressed and less satisfied with their lives. This so-called helicopter parenting style negatively affects students' well-being by violating their need to feel both autonomous and competent. The work, by Holly Schiffrin and colleagues from the University of Mary Washington in the United States, is published online in Springer's Journal of Child and Family Studies. Parental overinvolvement may lead to negative outcomes in children, including ...

JACKSONVILLE, Fla. — Researchers at Mayo Clinic have discovered an abnormal protein that accumulates in the brains of many patients affected with two common neurodegenerative disorders — amyotrophic lateral sclerosis, also known as ALS or Lou Gehrig's disease, and frontotemporal dementia. They say their findings have uncovered a potentially new therapeutic target and biomarker that would allow clinicians to confirm diagnosis of the diseases. The study is published online today in the journal Neuron. The Mayo research team, led by scientists at Mayo Clinic's campus in ...
