MADISON – Hunters have been credited with being strong conservation advocates for numerous game species in multiple countries. Would initiating a wolf hunt invoke the same advocacy for the carnivores? It's a pressing question as gray wolves were removed from the federal endangered species list in some western states this past May and are poised for delisting in 2012 in Wisconsin, Minnesota, Michigan and other areas of the Midwest. But newly released public opinion surveys conducted in Wisconsin and the northern Rockies suggest that wolves are in a class by themselves ...

WASHINGTON – Social media present risks and benefits to children but parents who try to secretly monitor their kids' activities online are wasting their time, according to a presentation at the 119th Annual Convention of the American Psychological Association. "While nobody can deny that Facebook has altered the landscape of social interaction, particularly among young people, we are just now starting to see solid psychological research demonstrating both the positives and the negatives," said Larry D. Rosen, PhD, professor of psychology at California State University, ...

WASHINGTON – People who are cyberstalked or harassed online experience higher levels of stress and trauma than people who are stalked or harassed in person, according to a presentation at the American Psychological Association's 119th Annual Convention. "Increasingly, stalkers use modern technology to monitor and torment their victims, and one in four victims report some form of cyberstalking, such as threatening emails or instant messaging," said Elizabeth Carll, PhD, in a talk entitled, "Electronic Harassment and Cyberstalking: Intervention, Prevention and Public Policy." Emotional ...

WASHINGTON, D.C. – The path of success for Nobel Prize laureates in the sciences isn't a straight shot from obscurity to never-ending scientific superstardom, a new study reveals. Instead, many laureates see their Nobel-winning idea grow in acceptance from their first related scientific article to their most successful publication. But their later work related to the Nobel idea gains less acceptance, and many times is no more accepted by the scientific community than their very first efforts. "In many cases, we found that Nobel laureates' final publication on their ...

SEATTLE, WA—The most common kind of chronically irregular heartbeat, known as atrial fibrillation, is associated with a greater risk of dementia, including Alzheimer's disease. This discovery by scientists at Group Health Research Institute and their collaborators was published online in advance of print on August 1 in the Journal of the American Geriatrics Society. "Both atrial fibrillation and dementia increase with age," said Sascha Dublin, MD, PhD, a Group Health Research Institute assistant investigator who led the research. "Before our prospective cohort study, ...

WASHINGTON — High schools in Virginia where students reported a high rate of bullying had significantly lower scores on standardized tests that students must pass to graduate, according to research presented at the 119th Annual Convention of the American Psychological Association. "Our study suggests that a bullying climate may play an important role in student test performance," said Dewey Cornell, PhD, a clinical psychologist and professor of education at the University of Virginia. "This research underscores the importance of treating bullying as a schoolwide problem ...

Columbia University Medical Center researchers have shown that new, or "de novo," protein-altering mutations—genetic errors that are present in patients but not in their parents—play a role in more than 50 percent of "sporadic" —i.e., not hereditary—cases of schizophrenia. The findings will be published online on August 7, 2011, in Nature Genetics. A group led by Maria Karayiorgou, MD, and Joseph A. Gogos, MD, PhD, examined the genomes of patients with schizophrenia and their families, as well as healthy control groups. All were from the genetically isolated, European-descent ...

AMHERST, Mass. – The discovery of a fundamental, previously unknown property of microbial nanowires in the bacterium Geobacter sulfurreducens that allows electron transport across long distances could revolutionize nanotechnology and bioelectronics, says a team of physicists and microbiologists at the University of Massachusetts Amherst. Their findings reported in the Aug. 7 advance online issue of Nature Nanotechnology may one day lead to cheaper, nontoxic nanomaterials for biosensors and solid state electronics that interface with biological systems. Lead microbiologist ...

Long before they knew they were doing it – as long ago as the Wright Brother's first airplane engine – metallurgists were incorporating nanoparticles in aluminum to make a strong, hard, heat-resistant alloy. The process is called solid-state precipitation, in which, after the melt has been quickly cooled, atoms of alloying metals migrate through a solid matrix and gather themselves in dispersed particles measured in billionths of a meter, only a few-score atoms wide. Key to the strength of these precipitation-hardened alloys is the size, shape, and uniformity of the ...

A new resource to define the roles of microRNAs is announced today in Nature Biotechnology. The resource, called mirKO, gives researchers access to tools to investigate the biological role and significance for human health of these enigmatic genes. mirKO is a "library" of mutant mouse embryonic stem (ES) cells in which individual, or clustered groups of microRNA genes, have been deleted. Using these tools researchers can create cells or mice lacking specific microRNAs, study expression using fluorescent markers, or inactivate the gene in specific tissues or at specific ...

Chapel Hill, NC – Cells are the building blocks of the human body. They are a focus of scientific study, because when things go wrong at the cellular and molecular level the consequences for human health are often significant. A new finding based on multiple collaborations between UNC and Duke scientists over several years points to new avenues for investigation of cell metabolism that may provide insights into diseases ranging from neurodegenerative disorders like Parkinson's and Alzheimer's disease to certain types of cancers. The finding, published today in the ...

Animal's brains are only roughly aware of how high-up they are in space, meaning that in terms of altitude the brain's 'map' of space is surprisingly flat, according to new research. In a study published online today in Nature Neuroscience, scientists studied cells in or near a part of the brain called the hippocampus, which forms the brain's map of space, to see whether they were activated when rats climbed upwards. The study, supported by the Wellcome Trust, looked at two types of cells known to be involved in the brain's representation of space: grid cells, which ...

European legislation restricts animal testing within the pharmaceutical and cosmetic industries and companies are increasingly looking at alternative systems to ensure that their products are safe to use. Research published in BioMed Central's open access journal BMC Genomics demonstrates that the response of laboratory grown human cells can now be used to classify chemicals as sensitizing, or non-sensitizing, and can even predict the strength of allergic response, so providing an alternative to animal testing. Allergic contact dermatitis can result in itching and eczema ...

August 8th, 2011, Shenzhen, China – BGI, the world's largest genomics organization, Peking University Shenzhen Hospital and Shenzhen Second People's Hospital, announced today that the study on frequent mutations of chromatin remodeling genes in transitional cell carcinoma (TCC) of the bladder was published online in Nature Genetics. This study provides a valuable genetic basis for future studies on TCC, suggesting that aberration of chromatin regulation might be one of the features of bladder cancer. Bladder cancer is the ninth most common type of cancer worldwide, which ...

CAMBRIDGE, Mass. (August 7, 2011) – The human genome is peppered with repeated DNA elements that can vary from a few to thousands of consecutive copies of the same sequence. During meiosis—the cell division that produces sperm and eggs—repetitive elements place the genome at risk for dangerous rearrangements from genome reshuffling. This recombination typically does not occur in repetitive DNA, in part because much of it is assembled into specialized heterochromatin. Other mechanisms that restrain recombination in repetitive DNA have remained elusive, until now. In a ...

Philadelphia, PA, August 8, 2011 – Researchers have gained a new understanding of the way in which growing tumors are fed and how this growth can be slowed via angiogenesis inhibitors that eliminate the blood supply to tumors. This represents a step forward towards developing new anti-cancer drug therapies. The results of this study have been published today in the September issue of The American Journal of Pathology. "The central role of capillary sprouting in tumor vascularization makes it an attractive target for anticancer therapy. Our observations suggest, however, ...

Philadelphia, PA, August 8, 2011 – Researchers have demonstrated the feasibility of focused fetal gene expression analysis of target genes found in amniotic fluid using Standardized NanoArray PCR (SNAP) technology. This analysis could be used to monitor fetal development, enabling clinicians to determine very early in pregnancy whether fetal organ systems are developing normally. The study appears today in the September issue of The Journal of Molecular Diagnostics. Using a previously developed SNAP gene panel as proof of concept, investigators from the Floating Hospital ...

Two new studies have found that smokers who tend to take their first cigarette soon after they wake up in the morning may have a higher risk of developing lung and head and neck cancers than smokers who refrain from lighting up right away. Published early online in Cancer, a peer-reviewed journal of the American Cancer Society, the results may help identify smokers who have an especially high risk of developing cancer and would benefit from targeted smoking interventions to reduce their risk. Cigarette smoking increases one's likelihood of developing various types of ...

A new technique that stimulates heart muscle cells with low-energy light raises the possibility of a future light-controlled pacemaker, researchers reported in Circulation: Arrhythmia & Electrophysiology, a journal of the American Heart Association. "Electronic cardiac pacemakers and defibrillators are well established and successful technologies, but they are not without problems, including the breakage of metal leads, limited battery life and interference from strong magnetic fields," said Emilia Entcheva, Ph.D., senior author of the study and associate professor of ...

Siblings of those who have been hospitalized with potentially lethal blood clots in the legs or pelvis are more likely to also suffer the disorder than those with healthy siblings, according to research published in Circulation: Journal of the American Heart Association. The Swedish study is the first to show a direct correlation between venous thromboembolism (VTE) and family risk in a nationwide setting, sorted by age and gender. VTE consists of deep vein thrombosis (DVT), which typically involves blood clots that form in the deep veins of the leg or pelvis, and ...

An undergraduate student has overcome a major hurdle in the development of invisibility cloaks by adding an optical device into their design that not only remains invisible itself, but also has the ability to slow down light. The optical device, known as an 'invisible sphere', would slow down all of the light that approaches a potential cloak, meaning that the light rays would not need to be accelerated around the cloaked objects at great speeds ― a requirement that has limited invisibility cloaks to work only in a specified region of the visible spectrum. This ...

The development of drugs for brain-related conditions is not an efficient process; only 8% of candidate drugs that enter clinical trials gain FDA approval. A key reason for this low success rate is a lack of preclinical tests that accurately predict drug efficacy and detect unwanted side effects. But now, Jeremy Nathans and colleagues, at Johns Hopkins University School of Medicine, Baltimore, have developed a new preclinical approach that they hope can be used alongside current strategies to guide more efficient drug development for brain-related conditions. In the study, ...
