Taste strongly influences food and beverage intake, including alcohol. Furthermore, genetic variation in chemosensory genes can explain variability in individual perception of and preference for alcoholic drinks. A new study has examined the relationship between variation in alcohol-related sensations and polymorphisms in bitter taste receptors genes previously linked to alcohol intake, and for the first time, polymorphisms in a burn receptor gene. The findings indicate that genetic variations in taste receptors influence intensity perceptions. Results will be published ...

Following a doubling of the incidence and prevalence of diabetes in the U.S. from 1990-2008, new data suggest a plateauing of the rate between 2008 and 2012 for adults, however the incidence continued to increase in Hispanic and non-Hispanic black adults, according to a study in the September 24 issue of JAMA. Although there has been an increase in the prevalence and incidence of diabetes in the United States in recent decades, no studies have systematically examined long-term, national trends of this disease, according to background information in the article. Linda ...

An intervention for pregnant women that included a computerized, interactive decision-support guide regarding prenatal genetic testing, and no cost for testing, resulted in less prenatal test use and more informed choices, according to a study in the September 24 issue of JAMA. Since the introduction of amniocentesis, prenatal genetic testing guidelines have focused on identifying women at increased risk of giving birth to an infant with Down syndrome or other chromosomal abnormalities, for whom invasive diagnostic testing should be recommended. Prenatal genetic testing ...

An analysis of 70 studies finds that use of the diagnostic imaging procedure of fludeoxyglucose F18 (FDG)-positron emission tomography (PET) combined with computed tomography (CT) may not reliably distinguish benign disease from lung cancer in populations with endemic (high prevalence) infectious lung disease compared with nonendemic regions, according to a study in the September 24 issue of JAMA. Depending on the risk for cancer, diagnostic guidelines suggest or recommend FDG combined with PET as a noninvasive test to assess the risk of cancer or benign disease, according ...

A new analysis of published studies found that FDG-PET technology is less accurate in diagnosing lung cancer versus benign disease in regions where infections like histoplasmosis or tuberculosis are common. Misdiagnosis of lung lesions suspicious for cancer could lead to unnecessary tests and surgeries for patients, with additional potential complications and mortality. Histoplasmosis and other fungal diseases are linked to fungi that are often concentrated in bird droppings and are found in soils. The study by investigators at Vanderbilt University and the Tennessee ...

SALT LAKE CITY, Sept. 23, 2014 – What's rocky, about a mile wide, orbits between Mars and Jupiter and poses no threat to Earth? An asteroid named "Univofutah" after the University of Utah. Discovered on Sept. 8, 2008, by longtime Utah astronomy educator Patrick Wiggins, the asteroid also known as 391795 (2008 RV77) this month was renamed Univofutah by the International Astronomical Union's Minor Planet Center in Cambridge, Massachusetts. "It's neat," Wiggins says. "There aren't too many other universities on the whole planet with asteroids named after them. So that ...

The successful rise and fall of an athlete's moving body relies on an orchestrated response of bones, joints, ligaments and tendons, putting the many angles and intersecting planes – literally the geometry – of a critical part like a knee joint to the test. But it's more than just a footfall error at the root of one of the most devastating of sports injuries: the ACL or anterior cruciate ligament tear. In fact, size – of the femoral notch that sits at the center of the knee joint – and volume of the ACL combine to influence the risk of suffering a noncontact ACL injury. ...

COLUMBIA, Mo. – Infants' vocalizations throughout the first year follow a set of predictable steps from crying and cooing to forming syllables and first words. However, previous research had not addressed how the amount of vocalizations may differ between hearing and deaf infants. Now, University of Missouri research shows that infant vocalizations are primarily motivated by infants' ability to hear their own babbling. Additionally, infants with profound hearing loss who received cochlear implants to help correct their hearing soon reached the vocalization levels of their ...

Edmonton—Cleaning up oil sands tailings has just gotten a lot greener thanks to a novel technique developed by University of Alberta civil engineering professors that uses solar energy to accelerate tailings pond reclamation efforts by industry. Instead of using UV lamps as a light source to treat oil sands process affected water (OSPW) retained in tailings ponds, professors Mohamed Gamal El-Din and James Bolton have found that using the sunlight as a renewable energy source treats the wastewater just as efficiently but at a much lower cost. "We know it works, so now ...

Antarctic fish that manufacture their own "antifreeze" proteins to survive in the icy Southern Ocean also suffer an unfortunate side effect, researchers funded by the National Science Foundation (NSF) report: The protein-bound ice crystals that accumulate inside their bodies resist melting even when temperatures warm. "We discovered what appears to be an undesirable consequence of the evolution of antifreeze proteins in Antarctic notothenioid fish," said University of Oregon doctoral student Paul Cziko, who led the research with University of Illinois animal biology ...

Genomic medicine is rapidly developing, bringing with its advances promises of individualized genetic information to tailor and optimize prevention and treatment interventions. Genetic tests are already guiding treatments of the human immunodeficiency virus (HIV) and hepatitis c virus (HPC), and emerging research is showing genetic variants may be used to screen for an individual's susceptibility to addiction to a substance, and even inform treatments for addiction. While there appear to be many benefits inherent in the development of this field and related research, ...

(PHILADELPHIA) – Researchers have encountered variants or isoforms in microRNAs (miRNAs) before, but assumed that these variants were accidental byproducts. A recent study, published in the journal Oncotarget this month, shows that certain so called isomiRs have abundances that depend on geographic subpopulations and gender and that the most prevalent variant of a given miRNA may not be the one typically listed in the public databases. "This study shows that microRNA isoforms are much more common than we had previously assumed. The fact that some isoforms are shared by ...

In this issue of PLOS Medicine, Clara Menendez from the Barcelona Institute for Global Health (ISGlobal), Spain, and colleagues report results from two large randomized controlled trials conducted in Africa to test an alternative drug for malaria prevention in HIV-negative and HIV-positive pregnant women. Pregnant women and their unborn children are at a high risk for complications from malaria infection, and finding new treatment options is important because the malaria parasites are becoming increasingly resistant to the existing WHO-recommended drug sulphadoxine-pyrimethamine ...

OAK BROOK, Ill. (September 23, 2014) – Both patients and healthcare professionals believe diagnosis of extracolonic malignancy with screening computed tomography (CT) colonography greatly outweighs the potential disadvantages of subsequent radiologic or invasive follow-up tests precipitated by false-positive diagnoses, according to a new study published in the October issue of the journal Radiology. Diagnostic tests used for cancer screening programs usually target a specific organ. However, when screening for colorectal cancer with CT colonography, abdominal and pelvic ...

IMPACT The community college system represents a potential source of student diversity for medical schools and physicians who will serve poor communities; however, there are significant challenges to enhancing the pipeline from community colleges to four-year universities to medical schools. The authors recommend that medical school and four-year university recruitment, outreach and admissions practices be more inclusive of community college students. FINDINGS Researchers from UCLA, UC San Francisco and San Jose City College found that, among students who apply to and ...

Hilo, Hawai`i–The Earth's soils store four times more carbon than the atmosphere and small changes in soil carbon storage can have a big effect on atmospheric greenhouse gas concentrations. A new paper in the journal Nature Climate Change concludes that climate warming does not accelerate soil organic carbon decomposition or affect soil carbon storage, despite increases in ecosystem productivity. The research, led by U.S. Forest Service Research Ecologist Dr. Christian Giardina, with the agency's Institute of Pacific Islands Forestry, Pacific Southwest Research Station, ...

EUGENE, Ore. -- Women living where rates of infectious disease are high, according to theory, prefer men with faces that shout testosterone when choosing a mate. However, an international study says not so much, says University of Oregon anthropologist Lawrence S. Sugiyama. The new study, on which Sugiyama is one of 22 co-authors, ended with that theory crumbling amid patterns too subtle to detect when tested with 962 adults drawn from 12 populations living in various economic systems in 10 nations. The study -- coordinated by Ian S. Penton-Voak of the School of Experimental ...

PITTSBURGH – When the body forms new tissues during the healing process, cells must be able to communicate with each other. For years, scientists believed this communication happened primarily through chemical signaling. Now researchers at Carnegie Mellon University and the University of Pittsburgh have found that another dimension – mechanical communication – is equally if not more crucial. The findings, published in this week's issue of the Proceedings of the National Academy of Sciences, could lead to advancements in treatments for birth defects and therapies for cancer ...

Scientists often measure the effects of temperature on insects to predict how climate change will affect their distribution and abundance, but a Dartmouth study shows for the first time that insects' fear of their predators, in addition to temperature, ultimately limits how fast they grow. "In other words, it's less about temperature and more about the overall environmental conditions that shape the growth, survival and distribution of insects." says the study's lead author Lauren Culler, an Arctic postdoctoral researcher at Dartmouth. The study appears in the journal ...

West Orange, NJ. September 23, 2014. Kessler Foundation scientists have published a study showing that use of a foot drop stimulator during a task-specific movement for 4 weeks can retrain the neuromuscular system. This finding indicates that applying the foot drop stimulator as rehabilitation intervention may facilitate recovery from this common complication of stroke. "EMG of the tibialis anterior demonstrates a training effect after utilization of a foot drop stimulator," was published online ahead of print on July 2 by NeuroRehabilitation (doi:10.3233/NRE-141126). The ...

CORVALLIS, Ore. – A recent Oregon survey about an exercise DVD that adds short breaks of physical activity into the daily routine of elementary school students found it had a high level of popularity with both students and teachers, and offered clear advantages for overly sedentary educational programs. Called "Brain Breaks," the DVD was developed and produced by the Healthy Youth Program of the Linus Pauling Institute at Oregon State University, and is available nationally. Brain Breaks leads children in 5-7 minute segments of physical activity, demonstrated by OSU ...

Scientists who study patterns in survey results might be dealing with data on language rather than what they're really after -- attitudes -- according to an international study involving the University of Colorado Boulder. The study, published in the journal PLOS ONE, found that people naturally responded to surveys by selecting answer options that were similar in language to each other as they navigated from one question to another, even when the similarities were subtle. For the study, researchers looked specifically at surveys on organizational behavior, such as ...

Boulder, Colo., USA - An astonishing new rock formation has been revealed in the Colorado Rockies, and it exists in a deeply perplexing relationship with older rocks. Named the Tava sandstone, this sedimentary rock forms intrusions within the ancient granites and gneisses that form the backbone of the Front Range. The relationship is fascinating because it is backward: ordinarily, it is igneous rocks such as granite that would that intrude into sedimentary rocks. According to authors Christine Smith Siddoway and George E. Gehrels, to find sandstone injected into granite ...

Men who are already obese as teenagers could grow up to earn up to 18 percent less than their peers of normal weight. So says Petter Lundborg of Lund University, Paul Nystedt of Jönköping University and Dan-olof Rooth of Linneas University and Lund University, all in Sweden. The team compared extensive information from Sweden, the United Kingdom and the United States, and the results are published in Springer's journal Demography. The researchers analyzed large-scale data of 145,193 Swedish-born brothers who enlisted in the Swedish National Service for mandatory military ...

Research by Rice University scientists who are fighting a cyberwar against cancer finds that the immune system may be a clinician's most powerful ally. "Recent research has found that cancer is already adept at using cyberwarfare against the immune system, and we studied the interplay between cancer and the immune system to see how we might turn the tables on cancer," said Rice University's Eshel Ben-Jacob, co-author of a new study this week in the Early Edition of the Proceedings of the National Academy of Sciences. Ben-Jacob and colleagues at Rice's Center for Theoretical ...
