DAVIE, Fla.-- The diverse patterns on the diamondback terrapins' intricately grooved shell may be their claim to fame, but a newly published U.S. Geological Survey study of the genetic variation underneath their shell holds one key to rescuing these coastal turtles. Listed as an endangered species in Rhode Island and deemed threatened in Massachusetts, the terrapin is the only turtle in North America that spends its entire life in coastal marshes and mangroves. Seven different subspecies of terrapins are currently recognized by scientists based on external traits, such ...

(PHILADELPHIA)—When cancer progresses and spreads to the bone, patients often suffer debilitating pain. Now, a new phase III clinical trial shows that non-invasive magnetic resonance guided focused ultrasound treatment that heats the cancer within the bone, relieves pain and improves function for most patients when other treatment options are limited. The results were published in the Journal of the National Cancer Institute (JNCI). Magnetic resonance guided focused ultrasound surgery (MRgFUS) is a technique that's been safely used to treat thousands of women with uterine ...

PULLMAN, Wash. – Testing conventional wisdom with science, recently published research from Washington State University reveals how different flavors "finish," or linger, on the palate following a sip of wine. "A longer finish is associated with a higher quality wine, but what the finish is, of course, makes a huge difference," said sensory scientist Carolyn Ross. The study is one of the first to look at how different flavor components finish when standing alone or interacting with other compounds in white wines. The idea for the work began with a question from one of ...

ROCHESTER, Minn. — A recent Mayo Clinic Proceedings article links some nerve damage after hip surgery to inflammatory neuropathy. Historically, nerve damage from hip surgery has been attributed to mechanical factors caused by anesthesiologists or surgeons, such as positioning of the patient during surgery or direct surgical injury of the nerves. In this study, researchers examined patients who developed inflammatory neuropathies, where the immune system attacks the nerves, leading to weakness and pain. Inflammatory neuropathies may be treated with immunotherapy. "Neuropathy ...

Ineffective social and political institutions make people more likely to favour their family and own local social group, while good institutions make them more likely to follow impersonal rules that are fair to everyone, suggests a forthcoming study in the journal Human Nature. A series of experiments found that people in societies with supportive government services, food security and institutions that meet their basic needs were very likely to follow impartial rules about how to give out money. By contrast, those without effective, reliable institutions showed favouritism ...

WASHINGTON, DC, May 5, 2014 — Work-family conflict is increasingly common among U.S. workers, with about 70 percent reporting struggles balancing work and non-work obligations. A new study by University of Minnesota sociologists Erin L. Kelly, Phyllis Moen, Wen Fan, and interdisciplinary collaborators from across the country, shows that workplaces can change to increase flexibility, provide more support from supervisors, and reduce work-family conflict. The study, titled, "Changing Work and Work-Family Conflict: Evidence from the Work, Family, and Health Network," was ...

SALT LAKE CITY, May 5, 2014 – When University of Utah biologists set out cotton balls treated with a mild pesticide, wild finches in the Galapagos Islands used the cotton to help build their nests, killing parasitic fly maggots to protect baby birds. The researchers say the self-fumigation method may help endangered birds and even some mammals. "We are trying to help birds help themselves," says biology professor Dale Clayton, senior author of a study outlining the new technique. The findings were published online May 5, 2014, in the journal Current Biology. "Self-fumigation ...

Researchers have found a way to protect threatened Darwin's finches on the Galápagos Islands from deadly parasitic nest flies in a manner that's as simple as it is ingenious: by offering the birds insecticide-treated cotton for incorporation into their nests. The study, reported in the Cell Press journal Current Biology on May 5, shows that the birds will readily weave the protective fibers in. What's more, the researchers find that just one gram of treated cotton is enough to keep a nest essentially parasite-free. The findings come as welcome news for the future of Darwin's ...

Turtles are more closely related to birds and crocodilians than to lizards and snakes, according to a study from Dartmouth, Yale and other institutions that examines one of the most contentious questions in evolutionary biology. The findings appear in the journal Evolution & Development. A PDF of the study is available on request. The research team looked at how the major groups of living reptiles, which number more than 20,000 species, are interrelated. The relationships of some reptile groups are well understood -- birds are most closely related to crocodilians among ...

BOULDER -- Ozone pollution across the continental United States will become far more difficult to keep in check as temperatures rise, according to new research led by the National Center for Atmospheric Research (NCAR). The detailed study shows that Americans face the risk of a 70 percent increase in unhealthy summertime ozone levels by 2050. This is because warmer temperatures and other changes in the atmosphere related to a changing climate, including higher atmospheric levels of methane, spur chemical reactions that lead to ozone. Unless emissions of specific pollutants ...

In the largest family study on autism spectrum disorder (ASD) to date, researchers from the Icahn School of Medicine at Mount Sinai, along with a research team from the Karolinska Institutet in Stockholm Sweden and King's College in London found that individual risk of ASD and autistic disorder increased with greater genetic relatedness in families – that is, persons with a sibling, half-sibling or cousin diagnosed with autism have an increased likelihood of developing ASD themselves. Furthermore, the research findings showed that "environmental" factors unique to the ...

HOUSTON – (May 5, 2014) – Reform of energy subsidies in oil-exporting countries can reduce carbon emissions and add years to oil exports, according to a new paper from Rice University's Baker Institute for Public Policy. "Navigating the Perils of Energy-Subsidy Reform in Exporting Countries" was authored by Jim Krane, the Wallace S. Wilson Fellow for Energy Studies at the Baker Institute, who specializes in energy geopolitics. The paper reviews the record of energy-subsidy reforms and argues that big exporters should reduce energy demand by raising prices, and that this ...

DALLAS – May 5, 2014 – Liver cancer survival rates could be improved if more people with cirrhosis are screened for tumors using inexpensive ultrasound scans and blood tests, according to a review by doctors at UT Southwestern Medical Center. The meta-analysis of 47 studies involving more than 15,000 patients found that the three-year survival rate was much higher among patients who received liver cancer screening— 51 percent for patients who were screened compared to 28 percent of unscreened patients. The review also found that cirrhosis patients who were screened for ...

PROVIDENCE, R.I. – A new study from the Bradley Hasbro Children's Research Center has found that family-based cognitive behavioral therapy (CBT) is beneficial to young children between the ages of five and eight with Obsessive-Compulsive Disorder (OCD). The study, now published online in JAMA Psychiatry, found developmentally sensitive family-based CBT that included exposure/response prevention (EX/RP) was more effective in reducing OCD symptoms and functional impairment in this age group than a similarly structured relaxation program. Jennifer Freeman, Ph.D., a staff ...

Scientists from the U.S. Food and Drug Administration (FDA) have identified a benign bacterium that shows promise in blocking Salmonella from colonizing raw tomatoes. Their research is published ahead of print in the journal Applied and Environmental Microbiology. When applied to Salmonella-contaminated tomato plants in a field study, the bacterium, known as Paenibacillus alvei, significantly reduced the concentration of the pathogen compared to controls. Outbreaks of Salmonella traced to raw tomatoes have sickened nearly 2,000 people in the US from 2000-2010, killing ...

Leona Cuttler, MD, knew in her core that the simple act of adding an outside eye could dramatically improve pediatric care. Today, a study of more than 16,000 patient visits published online in the journal Pediatrics proves Cuttler's thesis correct. The lead investigator on the research project, Cuttler succumbed to cancer late last year. But her colleagues are committed to seeing its lessons disseminated across the country. "It was an honor to work on this project with Dr. Cuttler," said study first author Sharon B. Meropol, MD, PhD, Assistant Professor, Departments ...

OAK RIDGE, Tenn., May 5, 2014 – For the first time, scientists have a clearer understanding of how to control the appearance of a superconducting phase in a material, adding crucial fundamental knowledge and perhaps setting the stage for advances in the field of superconductivity. The paper, published in Physical Review Letters, focuses on a calcium-iron-arsenide single crystal, which has structural, thermodynamic and transport properties that can be varied through carefully controlled synthesis, similar to the application of pressure. To make this discovery, researchers ...

Phosphate rich foods include processed cheese, Parmesan, cola, baking powder and most processed foods. Phosphates are widely used in the food industry as preservatives and pH stabilizers. When large quantities of phosphates are consumed, production of the FGF23 hormone is stimulated, which has a negative effect on the cardiovascular system. Reinhold Erben, the head of the Unit of Physiology, Pathophysiology and Biophysics at the Vetmeduni Vienna, warns that "our phosphate consumption is relevant for our state of health." Over 500 million people around the world suffer ...

New Rochelle, NY, May 5, 2014—Recent articles in the scientific literature and mass media that question the use of testosterone (T) therapy to treat T deficiency, or "low T," and assert the cardiovascular risks of T therapy, are flawed, according to a provocative Guest Editorial in Journal of Men's Health, a peer-reviewed publication from Mary Ann Liebert, Inc., publishers. The article is available free on the Journal of Men's Health website at http://www.liebertpub.com/jmh. In "Testosterone Therapy and Cardiovascular Risk: A Cautionary Tale" Martin Miner, MD, The Warren ...

If wine leaves a bitter, cotton-like coating on the tongue, neither the sense of taste nor the sense of smell is responsible. The traditional oak barrel character, also called barrique character, is perceived via the trigeminal nerve, which is responsible for, among other things, pain and temperature perception. This is reported in the journal "Chemical Senses" by a research team headed by Prof Dr Dr Dr Hanns Hatt from the Faculty of Biology and Biotechnology at the Ruhr-Universität. Patients with severed taste nerve do still taste barrique flavour In collaboration ...

COLUMBUS, Ohio—In the first study of its kind, researchers have determined that spending time with horses eases symptoms of Alzheimer's dementia. A collaboration between The Ohio State University, an equine therapy center and an adult daycare center found that people with Alzheimer's were able to safely groom, feed and walk horses under supervision—and the experience buoyed their mood and made them less likely to resist care or become upset later in the day. The small pilot study, which appears in the journal Anthrozoös, suggests that equine therapy—a treatment used ...

INDIANAPOLIS -- Researchers from Regenstrief Institute and Indiana University who followed over 30,000 older adults for a decade have found the rate of dementia diagnosis for patients with schizophrenia to be twice as high as for patients without this chronic, severe and disabling brain disorder. "Individuals with serious mental illnesses including schizophrenia appear to be living longer than earlier estimates suggested," said Hugh Hendrie, M.B., Ch.B., D.Sc., the geriatric psychiatrist who led the study. Dr. Hendrie is a Regenstrief Institute investigator, IU Center ...

With accelerating development of personalized cancer treatments matched to a patient's DNA sequencing, proponents say frontline physicians increasingly need help to maneuver through the complex genomic landscape to find the most effective, individualized therapy. In a paper published in the May 5 online issue of The Oncologist, researchers at the University of California, San Diego School of Medicine and Moores Cancer Center detail their experience evaluating 34 patients between December 2012 and June 2013 using a molecular tumor board – a new type of advisory group comprised ...

CLEVELAND – A new biomarker for esophageal cancer shows promise in improving screening for this deadly disease and its precursor, Barrett's esophagus. Amitabh Chak, MD, of University Hospitals Case Medical Center's Seidman Cancer Center and Case Western Reserve University School of Medicine, presented findings today at Digestive Disease Week in Chicago in a research forum titled "Aberrant Vimentin Methylation in Esophageal Brushings: A Biomarker for Detecting Barrett's Esophagus and Esophageal Adenocarcinoma" (embargoed May 5, 9:15 am CT). Dr. Chak and a research team ...

Aspiring game developers may want to bone up on their interpersonal skills. A forthcoming study from North Carolina State University and Microsoft Research finds that game developers need a suite of non-programming skills – including communication skills – that are considered less important in other fields of software development. "We wanted to evaluate which skills are important to game developers versus other fields of software development," says Dr. Emerson Murphy-Hill, an assistant professor of computer science at NC State and lead author of a paper on the work. "These ...
