Pittsburgh, Pennsylvania…A team of researchers has announced the discovery of a bizarre, bird-like dinosaur, named Anzu wyliei, that provides paleontologists with their first good look at a dinosaur group that has been shrouded in mystery for almost a century. Anzu was described from three specimens that collectively preserve almost the entire skeleton, giving scientists a remarkable opportunity to study the anatomy and evolutionary relationships of Caenagnathidae (pronounced SEE-nuh-NAY-thih-DAY)—the long-mysterious group of theropod dinosaurs to which Anzu belongs. The ...

A new study led by researchers at King's College London has found that premature babies supported immediately after birth by high-frequency oscillation - a type of breathing support - had better lung function as adolescents than those who received conventional ventilation. The children ventilated with the high frequency method also showed higher academic achievement in three of eight school subjects. The findings of the research, funded by the National Institute for Health Research (NIHR) Health Technology Assessment (HTA) Programme and the NIHR Biomedical Research Centre ...

Expanding on earlier research, Johns Hopkins researchers report that people with balance disorders or dizziness traceable to an inner-ear disturbance show distinctive abnormal eye movements when the affected ear is exposed to the strong pull of an MRI's magnetic field. The researchers first reported in 2011 in the journal Current Biology that an MRI's magnetic field pushes on the inner ear fluid responsible for maintaining balance, causing subjects undergoing MRI scans to have jerky eye movements and dizziness. Two new studies now suggest that these strong magnets could ...

DURHAM, N.C. – New guidelines for using statins to treat high cholesterol and prevent cardiovascular disease are projected to result in 12.8 million more U.S. adults taking the drugs, according to a research team led by Duke Medicine scientists. The findings for the first time quantify the impact of the American Heart Association's new guidelines, which were issued in November and generated both controversy and speculation about who should be given a prescription for statins. In an analysis of health data published online March 19, 2014, in the New England Journal ...

ITHACA, N.Y. – During Pleistocene era climate changes, neotropical orchid bees that relied on year-round warmth and wet weather found their habitats reduced by 30 to 50 percent, according to a Cornell University study that used computer models and genetic data to understand bee distributions during past climate changes. In previous studies, researchers have tracked male and female orchid bees and found that while females stay near their nests, male orchid bees travel, with one study concluding they roam as far as 7 kilometers per day. These past findings, corroborated ...

MINNEAPOLIS – People who develop diabetes and high blood pressure in middle age are more likely to have brain cell loss and other damage to the brain, as well as problems with memory and thinking skills, than people who never have diabetes or high blood pressure or who develop it in old age, according to a new study published in the March 19, 2014, online issue of Neurology®, the medical journal of the American Academy of Neurology. Middle age was defined as age 40 to 64 and old age as age 65 and older. "Potentially, if we can prevent or control diabetes and high blood ...

If you're rigid with rules and skimpy on affection and dialogue with your kids, they have a greater chance of being obese, according to research presented at the American Heart Association's Epidemiology & Prevention/Nutrition, Physical Activity & Metabolism Scientific Sessions 2014. Researchers followed a nationally representative group of 37,577 Canadian children aged 0 to 11. They compared kids whose parents are generally affectionate, have reasonable discussions about behavior with their child and set healthy boundaries (authoritative) with those whose parents were ...

A group of deaf adults using American Sign Language in a healthy lifestyle program successfully lost weight, according to a study presented at the American Heart Association's Epidemiology & Prevention/Nutrition, Physical Activity & Metabolism Scientific Sessions 2014. In the first randomized trial of lifestyle modification or weight reduction with deaf people using American Sign Language (ASL), participants had moderate improvements in their weight and level of physical activity after a 16-week program. "Existing mainstream programs focused on weight and weight-related ...

Teaching people how to flavor food with spices and herbs is considerably more effective at lowering salt intake than having them do it on their own, according to research presented at the American Heart Association's Epidemiology & Prevention/Nutrition, Physical Activity & Metabolism Scientific Sessions 2014. In the first phase of the study, 55 volunteers ate a low-sodium diet for four weeks. Researchers provided all foods and calorie-containing drinks. Salt is the main source of sodium in food. In the second phase, half of the study volunteers participated in a 20-week ...

Many U.S. women don't know most of the warning signs of a stroke, according to research presented at the American Heart Association's Epidemiology and Prevention/Nutrition, Physical Activity and Metabolism 2014 Scientific Sessions. The study is also published in the American Heart Association journal, Stroke. In a phone survey of 1,205 U.S. women: More than half (51 percent) of the women identified sudden weakness or numbness on one side of the face, arms or legs as a warning sign of a stroke. Less than half (44 percent) identified difficulty speaking or garbled speech ...

West Orange, NJ. March 20, 2014. Kessler Foundation scientists collaborated with colleagues in Spain to study memory and learning in patients with Parkinson Disease (PD). They found that the Parkinson group's ability to learn new information was significantly poorer when compared with the control group. The article was published ahead of print on February 24: Chiaravalloti ND, Ibarretxe-Bilbao N, Deluca J, Rusu O, Pena J, García-Gorostiaga I, Ojeda N.

Industry-sponsored, academic research leads to innovative patents and licenses, says a new analysis led by Brian Wright, University of California, Berkeley professor of agricultural and resource economics. The finding calls into question assumptions that corporate support skews science toward inventions that are less accessible and less useful to others than those funded by the government or non-profit organizations. The analysis, based on a study of two decades of records from the University of California system, is in today's science journal Nature. The National ...

Scientists have discovered a new, persistent structure in one of two radiation belts surrounding Earth. NASA's twin Van Allen Probes spacecraft have shown that high-energy electrons in the inner radiation belt display a persistent pattern that resembles slanted zebra stripes. Surprisingly, this structure is produced by the slow rotation of Earth, previously considered incapable of affecting the motion of radiation belt particles, which have velocities approaching the speed of light. Scientists had previously believed that increased solar wind activity was the primary ...

Hungry dogs would be expected to choose alternatives leading to more food rather than less food. But just as with humans and monkeys, they sometimes show a "less is more" effect. Thus conclude Kristina Pattison and Thomas Zentall of the University of Kentucky in the US, who tested the principle by feeding baby carrots and string cheese to ten dogs of various breeds. The findings are published in Springer's journal Animal Cognition. The research was conducted on dogs that would willingly eat cheese and baby carrots when offered, but showed a preference for the cheese. ...

PHILADELPHIA - A new clinical trial will soon begin testing whether early medical intervention in people at risk for Alzheimer's can slow down progression of disease pathology before symptoms emerge, as outlined in Science Translational Medicine. For the first time, people with no Alzheimer's disease symptoms will be told of their risk status before being asked to join the randomized controlled trial. As part of the overall prevention trial, Penn Medicine neurodegenerative ethics experts will monitor how learning about their risk of developing Alzheimer's impacts trial ...

An NJIT physicist is a collaborator in the discovery of a new structure in Earth's inner radiation belt -- a zebra-striped structure of highly energized electrons that could endanger humans in space and also damage low-earth navigation and communication satellites. And surprisingly, the new structure is produced not by solar activity but by Earth's slow rotation. Scientists had previously thought Earth's rotation couldn't affect the motion of radiation belt particles. The data supporting these discoveries comes from a measuring device aboard the two NASA Van Allen Probes ...

Researchers studying intestinal bacteria in newborns have characterized the gut bacteria of premature infants who go on to develop sepsis, a serious and potentially life-threatening condition caused by bacteria in the bloodstream. Their findings suggest new strategies for the early detection and prevention of severe bloodstream infections. The research was funded by several components of the National Institutes of Health (NIH)—the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), the National Human Genome Research Institute (NHGRI), ...

Researchers from the Santa Fe Institute and the Smithsonian Institution have pieced together a highly detailed picture of feeding relationships among 700 mammal, bird, reptile, fish, insect, and plant species from a 48 million year old lake and forest ecosystem. Their analysis of fossilized remains from the Messel deposit near Frankfurt, Germany, provides the most compelling evidence to date that ancient food webs were organized much like modern food webs. Their paper describing the research appears online and open access this week in Proceedings of the Royal Society ...

What immune response should a vaccine elicit to prevent HIV infection? Two studies published online today bring scientists closer to answering this question by identifying previously unrecognized attributes of antibodies that appear to have reduced the risk of HIV infection in the only clinical trial to show efficacy, albeit modest, of an experimental vaccine regimen in people. Earlier analyses of the results of that trial, known as RV144, suggested that antibodies to sites within a part of the HIV envelope called V1V2 correlated with reduced risk of HIV infection. These ...

Beverly, MA, March 19, 2014 – Long-term survivors after esophagectomy with gastric pull-up can enjoy a satisfying meal and good quality of life according to a new study from a team of researchers at the University of Southern California Keck School of Medicine, Los Angeles. This study concluded that pessimism about the long-term quality of life after an esophagectomy on the part of treating physicians and patients is unwarranted. It is published in the Journal of Thoracic and Cardiovascular Surgery, an official publication of the American Association for Thoracic Surgery. ...

DALLAS, March 19, 2014 — Texans, known for enjoying local beers and Dr Pepper soft drinks, now have a growing beverage industry that would appeal to James Bond, who is well-known for enjoying a good martini. Distillers are producing at least 17 Texas vodkas, researchers reported here today, and the most popular are, surprisingly, those that are a bit salty. Their report, "Shaken not stirred, y'all: A comparison of select Texas vodkas," covered the results of group tastings on the vodkas, as well as some surprising facts about the state's alcoholic beverage market. ...

Why do neurodegenerative diseases such as Alzheimer's affect only the elderly? Why do some people live to be over 100 with intact cognitive function while others develop dementia decades earlier? More than a century of research into the causes of dementia has focused on the clumps and tangles of abnormal proteins that appear in the brains of people with neurodegenerative diseases. However, scientists know that at least one piece of the puzzle has been missing because some people with these abnormal protein clumps show few or no signs of cognitive decline. A new study ...

New research led by the University of Exeter suggests that rising global temperatures will increase the quantity of the key greenhouse gas methane emitted from freshwater ecosystems to the Earth's atmosphere – which could in turn lead to further warming. The collaborative study, led by Dr Gabriel Yvon-Durocher from the University of Exeter, collated data from hundreds of laboratory experiments and field surveys to demonstrate that the speed at which methane fluxes increase with temperature was the same whether single species populations of methanogens, microbial communities ...
