DETROIT — With over $2.4 million in new federal funding, Wayne State University researchers, regional collaborators at Henry Ford Health System, the University of Michigan and Michigan State University, and community partners will study how exposures to stressors that are prevalent in the urban industrialized environment — both chemical and non-chemical — impact human health in Detroit and beyond. The grant, Center for Urban Responses to Environmental Stressors (CURES), is one of approximately 20 select P30 Core Centers funded by the National Institute of Environmental ...

June 17, 2014 (San Francisco) – People who live in neighborhoods that are conducive to walking experienced a substantially lower rate of obesity, overweight and diabetes than those who lived in more auto-dependent neighborhoods, according to a pair of studies presented at the American Diabetes Association's 74th Scientific Sessions®. Researchers in Canada compared adults living in the most and least "walkable" metropolitan areas in southern Ontario and found a lower risk of developing diabetes over a 10-year period for those who lived in neighborhoods with less sprawl, ...

DURHAM, N.C. -- Researchers at Duke Medicine have identified a new strategy for treating neuroblastoma using a modified version of heparin, a century-old injectable drug that thins the blood to prevent clots from forming. The study, conducted in mice and published June 17, 2014, in the Journal of Clinical Investigation, found that when heparin is altered to remove its blood-thinning properties, it can suppress and shrink neuroblastoma tumors without causing severe bleeding. "Our research translates mechanistic insights about heparin into a potential new therapy for ...

RIVERSIDE, Calif. — Where sustainability of water management is concerned, we must pay more attention to long-term solutions. Efficient water management and policy ought to be promoted at the local level. And a "portfolio approach" to water management is encouraged, one that includes information campaigns, different types of pricing, supply and reuse options, and technology-based rebate programs. These are some of the key messages that emerged from the first Urban Water Management Workshop that took place earlier this month at the University of California, Riverside. Sponsored ...

WASHINGTON D.C., June 17, 2014 – Using microscopic polymer light resonators that expand in the presence of specific gases, researchers at MIT's Quantum Photonics Laboratory have developed new optical sensors with predicted detection levels in the parts-per-billion range. Optical sensors are ideal for detecting trace gas concentrations due to their high signal-to-noise ratio, compact, lightweight nature, and immunity to electromagnetic interference. Although other optical gas sensors had been developed before, the MIT team conceived an extremely sensitive, compact way ...

WASHINGTON D.C., June 17, 2014 - Take a fine strand of silica fiber, attach it at each end to a slow-turning motor, gently torture it over an unflickering flame until it just about reaches its melting point and then pull it apart. The middle will thin out like a piece of taffy until it is less than half a micron across -- about 200 times thinner than a human hair. That, according to researchers at the Joint Quantum Institute at the University of Maryland, is how you fabricate ultrahigh transmission optical nanofibers, a potential component for future quantum information ...

BEIJING, CHINA (17 June 2014)—A dangerous strain of avian influenza, H7N9, that's causing severe illness and deaths in China may be inhabiting a small fraction of its potential range and appears at risk of spreading to other suitable areas of India, Bangladesh, Vietnam, Indonesia and the Philippines, according to a new study published today in the journal Nature Communications. Researchers from the Université Libre de Bruxelles (ULB), the International Livestock Research Institute (ILRI), Oxford University, and the Chinese Center of Disease Control and Prevention analyzed ...

COLUMBIA, Mo. – Researchers at the University of Missouri have proven that a compound initially developed as a cholesterol-fighting molecule not only halts the progression of breast cancer, but also can kill the cancerous cells. "Cholesterol is a molecule found in all animal cells and serves as a structural component of cell membranes," said Salman Hyder, the Zalk Endowed Professor in Tumor Angiogenesis and professor of biomedical sciences in the College of Veterinary Medicine and the Dalton Cardiovascular Research Center at MU. "Because tumor cells grow rapidly they ...

Depending on habitat availability, the endangered Indiana bat may be able to use its social connections to survive a certain amount of roost destruction, according to research by scientists at Virginia Tech and The Ohio State University. Alexander Silvis of Lynchburg, Ohio, and Andrew Kniowski of Boones Mill, Virginia, both doctoral students in Virginia Tech's College of Natural Resources and Environment, made findings from Ohio State field studies highly visual by applying graphic and spatial approaches to the data. "Social dynamics are important to bat roosting behavior," ...

Virginia Tech entomologists have developed a chromosome map for about half of the genome of the mosquito Aedes agypti, the major carrier of dengue fever and yellow fever. With the map, researchers can compare the chromosome organization and evolution between this mosquito and the major carrier of malaria, the Anopheles gambiae mosquito, to find ways to prevent diseases. "Despite looking somewhat similar, these mosquitoes diverged from each other about 150 million years ago. So, they are genetically further apart than humans and elephants," said Maria Sharakhova, a ...

"Increased to levels unprecedented" is how the Intergovernmental Panel on Climate Change (IPCC) described the rise of carbon dioxide, methane and nitrous oxide emissions in their report on the physical science basis of climate change in 2013. According to the US Environmental Protection Agency (EPA), the atmospheric concentration of methane, a greenhouse gas some 28 times more potent than carbon dioxide has been steadily growing since the 18th century and has now increased by 50 percent compared to pre-industrial levels, exceeding 1,800 parts per billion. The EPA attributes ...

A 20-minute classroom assessment that is less subjective than traditional in-class evaluations by principals can reliably measure classroom instruction and predict student standardized test scores, a team of researchers researchers reported. The assessment also provides immediate and meaningful feedback making it an important new tool for understanding and improving instructional quality, according to psychologists from the University of Rochester and the University of North Carolina at Chapel Hill. "Education researchers broadly agree that teachers matter," explained ...

VIDEO: Participants were asked to look at an image with moving sections blurred, while performing a cognitive 'n-back' task. Click here for more information. Montreal, June 17, 2014 — From animated ads on Main Street to downtown intersections packed with pedestrians, the eyes of urban drivers have much to see. But while city streets have become increasingly crowded with distractions, our ability to process visual information has remained unchanged for millions of years. ...

(Edmonton) There was a time, back in Nancy Cheyne's youth, when she combined the poise and grace of a ballerina with the daring and grit of a barrel racer. When she wasn't pursuing either of those pastimes, she bred sheepdogs, often spending hours on her feet grooming her furry friends at dog shows. All that seems like a lifetime ago. After 15 years of living with chronic lower-back pain, Cheyne, 64, can't walk from the disabled parking stall to the elevator at work without stopping for a rest. She eats mostly junk food because it hurts too much to stand over the stove ...

In a further test of a novel theory that suggests autism is the consequence of abnormal cell communication, researchers at the University of California, San Diego School of Medicine report that an almost century-old drug approved for treating sleeping sickness also restores normal cellular signaling in a mouse model of autism, reversing symptoms of the neurological disorder in animals that were the human biological age equivalent of 30 years old. The findings, published in the June 17, 2014 online issue of Translational Psychiatry, follow up on similar research published ...

A new approach to examining mammograms that takes into account a woman's health risk profile would reduce the number of cancer instances missed and also cut the number of false positives, according to a paper being presented at a conference of the Institute for Operations Research and the Management Sciences (INFORMS). Mehmet U.S. Ayvaci of the University of Texas Dallas will present his research group's findings about the role of risk profiling in the interpretation of mammograms at Advances in Decision Analysis, a conference sponsored by the INFORMS Decision Analysis ...

Researchers from Emory's Rollins School of Public Health discovered that an increase in the protein that helps store dopamine, a critical brain chemical, led to enhanced dopamine neurotransmission and protection from a Parkinson's disease-related neurotoxin in mice. Dopamine and related neurotransmitters are stored in small storage packages called vesicles by the vesicular monoamine transporter (VMAT2). When released from these packages dopamine can help regulate movement, pleasure, and emotional response. Low dopamine levels are associated with neurodegenerative diseases ...

(WASHINGTON, June 17, 2014) – New research, published online today in Blood, the Journal of the American Society of Hematology, suggests that the diversity of bacteria in the gastrointestinal tract of patients receiving stem cell transplants may be an important predictor of their post-transplant survival. A healthy gastrointestinal tract contains a balanced community of microorganisms (known as microbiota), largely comprised of "friendly" bacteria that aid digestion and are important to immune system function. When this community of microbes is compromised, the microbiota ...

New research from the University of Kent suggests that recent high levels of media coverage for climate change may have deflected attention and funding from biodiversity loss. In a paper published by the journal Bioscience, Kent conservationists also recommend that, to prevent biodiversity from becoming a declining priority, conservationists need to leverage the importance of climate change to obtain more funds and draw attention to other research areas such as biodiversity conservation. For the study, the team conducted a content analysis of newspaper coverage in ...

Compared with humans, computers have the capacity to solve problems at much greater speed. There are many problems, however, where computational speed alone is insufficient to find a correct or optimal solution, for example because the parameter "space" cannot be fully searched in a practical time. In contrast, the human mind can formulate expert knowledge specific for particular problems, providing a capacity to guide more efficient searches, although with more limited processing speed. The power of the human contribution can be multiplied through the efforts of a greater ...

University of Adelaide research into the origins of ovarian cancer has led to the discovery of a genetic pathway that could slow the spread of the cancer. The discovery is in part due to research into the genetics of humans' most distant mammalian relative, the platypus. In a paper published today in the journal PLOS ONE, researchers characterize a genetic pathway – involving piRNA genes – that is turned on in ovarian cancer. "This pathway is important for the development of the ovaries in drosophila flies but little is known about its role in the mammalian ovary," ...

Imaging and mapping of electric fields at radio frequencies (RF)* currently requires the use of metallic structures such as dipoles, probes and reference antennas. To make such measurements efficiently, the size of these structures needs to be on the order of the wavelength of the RF fields to be mapped. This poses practical limitations on the smallest features that can be measured. New theoretical and experimental work by researchers at the National Institute of Standards and Technology (NIST) and the University of Michigan suggests an innovative method to overcome ...

A study carried out at the Institute of Biomedicine of the University of Eastern Finland shows that a common mutation in the PNPLA3 gene combined with overweight results in elevated ALAT values in children. The ALAT value is an indicator of liver metabolism. In adults, this gene mutation is known to promote the accumulation of fat in the liver. The new results indicate that a healthy lifestyle is important already in childhood in order to prevent the accumulation of fat in the liver, and it is especially important for those carrying the risk gene. The results will be published ...
