URBANA, Ill. – Veterinarians and women's shelters can make it easier for abused women to decide to leave their homes, particularly when the abuser is using a beloved pet as part of a campaign to control his partner, reports a new University of Illinois study. He made me stand there and . . . watch [him kill my cat]. And he was like: That could happen to you, one woman in the study said. "These incidences are very symbolic of what the abuser is capable of doing. He's sending the message: I can do something just as severe to hurt you," said Jennifer Hardesty, a U of I ...

Three grants totaling more than $25 million over four years will help three research groups to develop authoritative information on the millions of genomic variants relevant to human disease and the hundreds that are expected to be useful for clinical practice. The awards are from the National Institutes of Health. More and more medical and research centers are sequencing the DNA of whole genomes (the body's entire genetic blueprint) or exomes (the genome's protein-coding region) of patients. Each time, millions of DNA differences in genes and the regions between the genes ...

Philadelphia, PA, September 25, 2013 – Limited health literacy can lead to difficulties in patients' self-care activities such as taking prescribed medications. Since a considerable amount of health information changes hands in the pharmacy setting, research by pharmacists into evaluating which tools are effective in practice can make a valuable contribution to goals set by the 2010 US National Action Plan to Improve Health Literacy and lead to improvements in communications and health care, say experts in this special themed issue on "Pharmacy, Medication Use, and the ...

BETHESDA, Md. (Sept. 25, 2013)—Several studies have shown that expecting a reward or punishment can affect brain activity in areas responsible for processing different senses, including sight or touch. For example, research shows that these brain regions light up on brain scans when humans are expecting a treat. However, researchers know less about what happens when the reward is actually received—or an expected reward is denied. Insight on these scenarios can help researchers better understand how we learn in general. To get a better grasp on how the brain behaves when ...

Drugged driving has been a safety issue of increasing public concern in the United States and many other countries but its role in motor vehicle crashes had not been adequately examined. In a new study conducted at Columbia University's Mailman School of Public Health, researchers assessed the association of driver drug use, as well as the combination of drugs and alcohol, with the risk of fatal crash. They found that drug use is associated with a significantly increased risk of fatal crash involvement, particularly when used in combination with alcohol. The study provides ...

A new research paper shows that a great number of nearby terrigenous pollen and charcoal have been found from the deep-sea sediments of the last 200 kyrs in Okinawa Trough. It is tesitfied that the continental shelf of the East China Sea was exposed and covered with the huge wetland and grassland ecosystems during the the last two glacial periods. They discovered that the variation of terrestrial sources is concordent with global glacial volume and sea-level changes at orbital-scale since 200 kyrs before present. Their work, entitled "A ~200 ka pollen record from Okinawa ...

DALLAS – Sept. 26, 2013 – In ongoing research aimed at battling obesity, UT Southwestern Medical Center researchers have deciphered how new fat cells are formed in energy-storing fat pads. In particular, researchers sought to find out the origin of "brown" fat cells and whether humans can make more of them in order to burn extra calories – a finding that could have significant impact in battling obesity and related diseases. "Much of the current excitement in the obesity field stems from recent observations highlighting that, even as adults, we have the ability to generate ...

A previously unknown genus of electric fish has been identified in a remote region of South America by a team of international researchers including University of Toronto Scarborough professor Nathan Lovejoy. The Akawaio penak, a thin, eel-like electric fish, was discovered in the shallow, murky waters of the upper Mazaruni River is northern Guyana. Lovejoy's team at UTSC analyzed tissue samples collected during a recent expedition by a researchers led by Hernán López-Fernández at the Royal Ontario Museum. By sequencing its DNA and reconstructing an evolutionary tree, ...

Parkinson disease, a neurodegenerative disorder in which both genetic and environmental factors play important roles, has been associated with epigenetic changes (those molecular modifications that alter the behavior of genes without changing the DNA sequence). Because accurate diagnosis is not easy for this disease, scientists are continuously trying to identify early signs of the disease that enable treatment before major neurological damage occurs. In an article published in the October issue of Epigenetics, those epigenetic changes appear to be great candidates as early ...

The deep-sea soft-sediment ecosystem in the immediate area of the 2010's Deepwater Horizon well head blowout and subsequent oil spill in the Gulf of Mexico will likely take decades to recover from the spill's impacts, according to a scientific paper reported in the online scientific journal PLoS One. The paper is the first to give comprehensive results of the spill's effect on deep-water communities at the base of the Gulf's food chain, in its soft-bottom muddy habitats, specifically looking at biological composition and chemicals at the same time at the same location. "This ...

Los Angeles, CA (September 25, 2013) For many international news followers, having a cup of coffee while reading the morning newspaper has turned into scrolling a Twitter feed to catch up on important news as it happens throughout the day. In a new article published in SAGE Open, researchers used data collected from Twitter to study readers' news preferences across the globe and discovered that different countries have stronger preference towards different types of articles – American and British readers are more drawn to opinion and world news, Spaniards to local and ...

A class of flame retardants that has been linked to learning difficulties in children has rapidly declined in pregnant women’s blood since the chemicals were banned in California a decade ago, according to a study led by researchers at UC San Francisco. Blood levels of polybrominated diphenyl ethers (PBDEs), tested in patients at the UCSF-affiliated San Francisco General Hospital and Trauma Center fell by two-thirds since they were last tested three years ago and found to be the highest levels reported among pregnant women anywhere in the world. The findings were ...

DURHAM, N.C. -- Coal-powered synthetic natural gas plants being planned in China would produce seven times more greenhouse gas emissions than conventional natural gas plants, and use up to 100 times the water as shale gas production, according to a new study by Duke University researchers. These environmental costs have been largely neglected in the drive to meet the nation's growing energy needs, the researchers say, and might lock China on an irreversible and unsustainable path for decades to come. "Using coal to make natural gas may be good for China's energy security, ...

Atlanta, September 25, 2013 -- Detailed evaluation of a prostate cancer tumor biopsy may predict treatment outcomes for image-guided radiation therapy (IGRT) or surgery for prostate cancer, according to research presented today at the American Society for Radiation Oncology's (ASTRO's) 55th Annual Meeting. The study results indicate that patients who have abnormal levels of breaks at common fragile sites (CFSs), sites within the chromosomes that are sensitive to DNA damage, are more likely to have their cancer to return -- treatment failure. These CFS break abnormalities ...

WASHINGTON, Sept. 25, 2013—To capture all the details of a crime scene, you might take many photos at close range. To get the whole scene at once, you could use a wide-angle or fisheye lens; but without an especially large lens you would be sacrificing the fine resolution that would help you catch that partial footprint you might otherwise have missed. Now a new type of miniature camera system promises to give users a big picture view without sacrificing high-resolution. Researchers from the University of California, San Diego will describe their novel device at The Optical ...

EAST LANSING, Mich. -- Materialistic people experience more stress from traumatic events such as terrorist attacks and are more likely to spend compulsively as a result, according to an international study led by a Michigan State University business professor. These possession-driven folks tend to have lower self-esteem than others, said Ayalla Ruvio, MSU assistant professor of marketing. "When the going gets tough, the materialistic go shopping," said Ruvio. "And this compulsive and impulsive spending is likely to produce even greater stress and lower well-being. Essentially, ...

Recent times have seen the world having to learn to deal with austerity, libel and new models of business. This all happens at a time when innovation is being promoted more vigorously than ever as a way out of crisis and as a foundation for future prosperity. As the report argues, increased governance of science and technology and the sense ...

Philadelphia, PA, September 25, 2013 – Prenatal cocaine exposure affects both behavior and brain. Animal studies have shown that exposure to cocaine during in utero development causes numerous disruptions in normal brain development and negatively affects behavior from birth and into adulthood. For ethical reasons, similar studies in humans have been more limited but some research has shown that children exposed prenatally to cocaine have impairments in attention, control, stress, emotion regulation, and memory. Research also suggests that such children may be more predisposed ...
