SEATTLE, WA, AUGUST 9, 2015 - Linking survey data with administrative records will enable the federal government to better gauge the effectiveness of social welfare programs such as food stamps and federal housing assistance, as well as the overall reach of federal antipoverty initiatives, Bruce D. Meyer today told a session audience at the 2015 Joint Statistical Meetings (JSM 2015) in Seattle. During a presentation titled "Using Linked Survey and Administrative Data to Better Measure Income: Implications for Poverty, Program Effectiveness, and Holes in the Safety Net," ...

TORONTO -- The practice of sexting may be more common than generally thought among adults. More than eight out of 10 people surveyed online admitted to sexting in the prior year, according to research presented at the American Psychological Association's 123rd Annual Convention. "Given the possible implications, both positive and negative, for sexual health, it is important to continue investigating the role sexting plays in current romantic and sexual relationships," said Emily Stasko, MS, MPH, of Drexel University, who presented the research. Stasko and her co-author, ...

Athens, Ga. - Recent research published in the journal Microsystems & Nanoengineering could eventually change the way people living with prosthetics and spinal cord injury lead their lives. Instead of using neural prosthetic devices--which suffer from immune-system rejection and are believed to fail due to a material and mechanical mismatch--a multi-institutional team, including Lohitash Karumbaiah of the University of Georgia's Regenerative Bioscience Center, has developed a brain-friendly extracellular matrix environment of neuronal cells that contain very little foreign ...

When the right gene is expressed in the right manner in the right population of stem cells, the developing mouse brain can exhibit primate-like features. In a paper publishing August 7th in the Open Access journal PLOS Biology, researchers at the Max Planck Institute of Molecular Cell Biology and Genetics (MPI-CBG) succeeded in mimicking the sustained expression of the transcription factor Pax6 as seen in the developing human brain, in mouse cortical progenitor cells. This altered the behavior of these cells to one that is akin to that of progenitors in the developing primate ...

The common baker's yeast (Saccharomyces cerevisiae) is used to make bread, wine and beer, and is the laboratory workhorse for a substantial proportion of research into molecular and cell biology. It was also the first non-bacterial living thing to have its genome sequenced, back in 1996. However, when the sequence of that genome emerged it appeared that the scientists were seeing double - the organism seemed to have two very different versions of many of its genes. How could this have happened? Researchers from the Centre for Genomic Regulation (CRG) Barcelona, Spain, ...

Berkeley -- While the eyes may be a window into one's soul, new research led by scientists at the University of California, Berkeley, suggests that the pupils could also reveal whether one is a hunter or hunted. An analysis of 214 species of land animals shows that a creature's ecological niche is a strong predictor of pupil shape. Species with pupils that are vertical slits are more likely to be ambush predators that are active both day and night. In contrast, those with horizontally elongated pupils are extremely likely to be plant-eating prey species with eyes on ...

This news release is available in French and German. Every year, more than a million fish are used for toxicity testing and scientific research in the EU alone, and around 400 fish are needed for a single fish early-life stage test. Such toxicity tests are often required by regulatory authorities for new chemical substances, as fish are particularly sensitive to contaminants in water at early developmental stages. However, the increasing use of experimental animals is ethically questionable. In addition, conventional tests are complex, expensive and take ...

Coral Gables, FL (August 7, 2015)--Two new studies show that the tone of a candidate's voice can influence whether he or she wins office. "Our analyses of both real-life elections and data from experiments show that candidates with lower-pitched voices are generally more successful at the polls," explains Casey Klofstad, associate professor of political science at the University of Miami College of Arts and Sciences, who is corresponding author on both studies. The first study, published online in Political Psychology, shows that candidates who ran in the 2012 U.S. ...

CRG researchers have proposed a new theory to explain the origin of whole genome duplication at the beginning of the yeast lineage. Yeasts are single-celled fungi that originated over 100 million years ago. The ability of these organisms to ferment carbohydrates is widely used for food and drink fermentation. Yeasts are also one of the most commonly used model organisms in research. For example, the yeast Saccharomyces cerevisiae, which is used to make bread, wine and beer, was the first eukaryotic organism to be sequenced (in 1996) and is a key model organism for studying ...

Medulloblastoma, the most commonly occurring malignant brain tumor in children, can be classified into four subgroups--each with a different risk profile requiring subgroup-specific therapy. Currently, subgroup determination is done after surgical removal of the tumor. Investigators at Children's Hospital Los Angeles have now discovered that these subgroups can be determined non-invasively, using magnetic resonance spectroscopy (MRS). The paper will be published online by the journal Neuro-Oncology (Oxford Press) on August 7. "By identification of the tumor subgroup ...

TORONTO - Hearing loss in adults is under treated despite evidence that hearing aid technology can significantly lessen depression and anxiety and improve cognitive functioning, according to a presentation at the American Psychological Association's 123rd Annual Convention. "Many hard of hearing people battle silently with their invisible hearing difficulties, straining to stay connected to the world around them, reluctant to seek help," said David Myers, PhD, a psychology professor and textbook writer at Hope College in Michigan who lives with hearing loss. In a ...

Philadelphia - A large randomized clinical trial of an emergency department (ED)-based program aimed at reducing incidents of excessive drinking and partner violence in women did not result in significant improvements in either risk factor, according to a new study from researchers at the Perelman School of Medicine at the University of Pennsylvania. Contrary to previous studies which found brief interventions in the ED setting to be effective for reducing alcohol consumption to safe levels and preventing subsequent injury among patients with hazardous drinking, the new ...

Capture and convert--this is the motto of carbon dioxide reduction, a process that stops the greenhouse gas before it escapes from chimneys and power plants into the atmosphere and instead turns it into a useful product. One possible end product is methanol, a liquid fuel and the focus of a recent study conducted at the U.S. Department of Energy's (DOE) Argonne National Laboratory. The chemical reactions that make methanol from carbon dioxide rely on a catalyst to speed up the conversion, and Argonne scientists identified a new material that could fill this role. With ...

For years chemotherapy has been one of most common methods of treating cancer, but it comes with the substantial drawback of effecting healthy cells in the same way that it effects cancerous cells. This means that a subject of chemotherapy can experience great pain and sickness as a side effect of the potentially lifesaving treatment. A solution to this problem is targeted therapy, or the use of drugs, which more specifically targets cancer cells while ignoring nearby healthy cells. Targeted therapy is dependent on drugs which are tailored to inhibited cancer cell growth, ...

A new test developed by UBC researchers allows physicians to measure the effects of gene silencing therapy in Huntington's disease and will support the first human clinical trial of a drug that targets the genetic cause of the disease. The gene silencing therapy being tested by UBC researchers aims to reduce the levels of a toxic protein in the brain that causes Huntington's disease. The test was developed by Amber Southwell, Michael Hayden, and Blair Leavitt of UBC's Centre for Molecular Medicine and Therapeutics and the Centre for Huntington Disease in collaboration ...

This news release is available in Japanese. There are no magic bullets for global energy needs. But fuel cells in which electrical energy is harnessed directly from live, self-sustaining chemical reactions promise cheaper alternatives to fossil fuels. To facilitate faster energy conversion in these cells, scientists disperse nanoparticles made from special metals called 'noble' metals, for example gold, silver and platinum along the surface of an electrode. These metals are not as chemically responsive as other metals at the macroscale but their atoms become more ...

Scientists searched the chromosomes of more than 4,000 Huntington's disease patients and found that DNA repair genes may determine when the neurological symptoms begin. Partially funded by the National Institutes of Health, the results may provide a guide for discovering new treatments for Huntington's disease and a roadmap for studying other neurological disorders. "Our hope is to find ways that we can slow or delay the onset of Huntington's devastating symptoms," said James Gusella, Ph.D., director of the Center for Human Genetic Research at Massachusetts General ...
