ATLANTA- Pregnant women who received the H1N1 influenza vaccine during the 2009 pandemic were less likely to have premature babies, and their babies weighed more on average. Influenza infection during pregnancy is associated with adverse infant outcomes such as preterm birth. Emory researchers from the Rollins School of Public Health, in a joint study with Kaiser Permanente of Georgia and the Mid-Atlantic States, evaluated the effectiveness of the H1N1 influenza vaccine in pregnant women against adverse infant outcomes during the 2009 pandemic. They compared birth outcomes ...

Researchers at Plymouth University, UK, believe that findings from fieldwork along the North Yorkshire coast reveal strong parallels between the Early Jurassic era of 180 million years ago and current climate predictions over the next century. Through geology and palaeontology, they've shown how higher temperatures and lower oxygen levels caused drastic changes to marine communities, and that while the Jurassic seas eventually recovered from the effects of global warming, the marine ecosystems that returned were noticeably different from before. The results of the Natural ...

A single mutation in a moth gene has been shown to be able to produce an entirely new scent. This has been shown in a new study led by researchers from Lund University in Sweden. In the long run, the researchers say that the results could contribute to tailored production of pheromones for pest control. Male moths can pick up the scent of a female moth from a distance of several hundred metres. The females produce sexual pheromones – scent substances that guide the males to them. There are around 180 000 species of moth and butterfly in the world, and most of them communicate ...

WASHINGTON--U.S. Naval Research Laboratory radio astronomer, Joseph Helmboldt, Ph.D., and researchers at Ohio State University Department of Civil, Environmental and Geodetic Engineering analyzed radio telescope interferometry and Global Positioning Satellite (GPS) data recorded of the ionosphere during one of the last underground nuclear explosions (UNEs) in the U.S., codenamed Hunters Trophy. Situated in the Plains of San Agustin, 50 miles west of Socorro, New Mexico, twenty-seven 25-meter parabolic dish antennas collectively make up the National Radio Astronomy Observatory's ...

The true cost of war is being masked by the secretive and largely unaccountable activities of a private security industry, according to a new study. These invisible costs of war – both in terms of casualties and financial resources – are not reported and are hard to find because contractors are not subject to the same reporting structures and laws as the regular military, and many of their activities are protected from Freedom of Information requests. Private security firms – usually run by former senior figures in the military, civil service or politics – are increasingly ...

ANN ARBOR, Mich. — An antidepressant drug used since the 1960s may also hold promise for treating sickle cell disease, according to a surprising new finding made in mice and human red blood cells by a team from the University of Michigan Medical School. The discovery that tranylcypromine, or TCP, can essentially reverse the effects of sickle cell disease was made by U-M scientists who have spent more than three decades studying the basic biology of the condition, with funding from the National Institutes of Health. Their findings, published in Nature Medicine, pave ...

EAST LANSING, Mich. — Today's consumers switch between media forms so often – from TV to laptops to smart phones – that capturing their attention with advertising has gone, as one CEO explained, from shooting fish in a barrel to shooting minnows. Now, a Michigan State University business scholar and colleagues have developed the most accurate model yet for targeting those fast-moving minnows. The research-based model predicts when during the day people use the varying forms of media and even when they are using two or more at a time, an increasingly common practice known ...

ANN ARBOR, Mich. — As cities across America work to reduce violence in tight budget times, new research shows how they might be able to target their efforts and police attention – with the help of high-powered computers and loads of data. In a newly published paper, University of Michigan Medical School researchers and their colleagues have used real police data from Boston to demonstrate the promise of computer models in zeroing in on violent areas. They combined and analyzed information in small geographic units, on police reports, drug offenses, and alcohol availability ...

Infrasonic waves from the meteor that broke up over Russia's Ural mountains last week were the largest ever recorded by the CTBTO's International Monitoring System. Infrasound is low frequency sound with a range of less than 10 Hz. The blast was detected by 17 infrasound stations in the CTBTO's network, which tracks atomic blasts across the planet. The furthest station to record the sub-audible sound was 15,000km away in Antarctica. The origin of the low frequency sound waves from the blast was estimated at 03:22 GMT on 15 February 2013. People cannot hear the low frequency ...

Researchers at North Carolina State University have developed a new type of nanoscale structure that resembles a "nano-shish-kebab," consisting of multiple two-dimensional nanosheets that appear to be impaled upon a one-dimensional nanowire. But looks can be deceiving, as the nanowire and nanosheets are actually a single, three-dimensional structure consisting of a single, seamless series of germanium sulfide (GeS) crystals. The structure holds promise for use in the creation of new, three-dimensional (3-D) technologies. The researchers believe this is the first engineered ...

Exactly how a crystal forms from solution is a problem that has occupied scientists for decades. Researchers at Eindhoven University of Technology (TU/e), together with researchers from Germany and the USA, are now presenting the missing piece. This classical theory of crystal formation, which occurs widely in nature and in the chemical industry, was under fire for some years, but is saved now. The team made this breakthrough by detailed study of the crystallization of the mineral calcium phosphate –the major component of our bones. The team published their findings yesterday ...

TORONTO, ON – A new study led by an international team of biologists has identified some of the brain chemicals that allow seals to sleep with half of their brain at a time. The study was published this month in the Journal of Neuroscience and was headed by scientists at UCLA and the University of Toronto. It identified the chemical cues that allow the seal brain to remain half awake and asleep. Findings from this study may explain the biological mechanisms that enable the brain to remain alert during waking hours and go off-line during sleep. "Seals do something biologically ...

Are we intellectually lazy? Yes we are, but we do know when we take the easy way out, according to a new study by Wim De Neys and colleagues, from the CNRS in France. Contrary to what psychologists believe, we are aware that we occasionally answer easier questions rather than the more complex ones we were asked, and we are also less confident about our answers when we do. The work is published online in Springer's journal Psychonomic Bulletin & Review. Research to date on human thinking suggests that our judgment is often biased because we are intellectually lazy, or ...

New York University College of Nursing's Professor Michele Shedlin, PhD, recently published a paper, "Sending-Country Violence and Receiving-Country Discrimination: Effects on the Health of Colombian Refugees in Ecuador," on-line in the Journal of Immigrant and Minority Health, February 2, 2013. Studies of immigrant health have historically focused on individual-level risk factors more than environmental/structural factors as salient mediating variables. Shedlin's research addresses the need to reach a more complete understanding of the migration process and vulnerabilities ...

As the name suggests, you can't digest resistant starch so it ends up in the bowel in pretty much the same form it entered your mouth. As unlovely as that seems, once in the bowel this resistant starch does some important things, including decreasing bowel pH and transit time, and increasing the production of short-chain fatty acids. These effects promote the growth of good bugs while keeping bad bugs at bay. A University of Colorado Cancer Center review published in this month's issue of the journal Current Opinion in Gastroenterology shows that resistant starch also helps ...

1. Acupuncture May be an Effective Alternative for Treating Seasonal Allergies Patients receiving acupuncture treatments for seasonal allergic rhinitis reported statistically significant improvements in symptoms and decreased use of medication compared to patients having standard treatment or sham acupuncture, but the clinical significance of the observed improvements is uncertain. Allergic rhinitis (stuffy or runny nose caused by allergies) is an extremely common condition that affects approximately 20 percent of the U.S. population. Despite the availability of effective ...

New York, NY—February 18, 2013—A new study by Columbia Engineering researchers finds that the infant brain does not control its blood flow in the same way as the adult brain. The paper, which the scientists say could change the way researchers study brain development in infants and children, is published in the February 18 Early Online edition of Proceedings of the National Academy of Sciences (PNAS). "The control of blood flow in the brain is very important" says Elizabeth Hillman, associate professor of Biomedical Engineering and of Radiology, who led the research study ...

When it comes to forming the droplets that make up clouds, a little oily and viscous organic material apparently doesn't matter that much. And that's good news for reducing the uncertainty of climate model predictions. Understanding cloud formation is essential for accurate climate modeling, and understanding cloud formation begins with the droplets that make up clouds. Droplets form when water vapor is attracted to particles floating in the atmosphere. These particles include dust, sea salt from the ocean, microorganisms, soot, sulfur – and organic material that can ...

Women appear to have a higher risk of implant failure than men following total hip replacement after considering patient-, surgery-, surgeon-, volume- and implant-specific risk factors, according to a report published Online First by JAMA Internal Medicine, a JAMA Network publication. Total hip replacement, also known as total hip arthroplasty (THA), is more often performed in women than men. Sex-specific risk factors and outcomes have been investigated in other major surgical procedures and, in theory, might be more important to study in THA because of anatomical differences ...

A study in Australia suggests that reduced lung function in infancy was associated with wheezing beyond childhood at 18 years of age, according to a report published Online First by JAMA Pediatrics, a JAMA Network publication. Abnormal airway function is characteristic of asthma and chronic obstructive airways disease, and other studies have suggested that reduced lung function is already apparent in childhood and tracks through adulthood. However, the relationship between the age of onset of airway dysfunction and wheeze, a symptom of obstructive airways disease, has ...

A team of scientists and surgeons from Newcastle are developing a new nasal spray from a marine microbe to help clear chronic sinusitis. They are using an enzyme isolated from a marine bacterium Bacillus licheniformis found on the surface of seaweed which the scientists at Newcastle University were originally researching for the purpose of cleaning the hulls of ships. Publishing in PLOS ONE, they describe how in many cases of chronic sinusitis the bacteria form a biofilm, a slimy protective barrier which can protect them from sprays or antibiotics. In vitro experiments ...

Maternal nutrition is important to a developing embryo and to the health of the child later in life. Supplementing the diet with specific vitamins is known to increase health of the foetus for example folic acid (vitamin B9) reduces the risk of spina bifida. However not everything an adult might consume is beneficial to a developing baby. New research published in BioMed Central's open access journal BMC Medicine shows that caffeine is linked to low birth weight babies and that caffeine from coffee in linked to increasing length of pregnancy. Along with nutrients and ...

ST. LOUIS – New research at Saint Louis University shows physicians do not talk to patients about the psychosocial impact and long-term risks of implanting cardioverter defibrillators (ICDs) to treat irregular heart rhythms, leaving them misinformed about how the device may affect quality of life. The article, titled 'Patient Perceptions, Physician Communication and the Implantable Cardioverter-Defibrillator,' was published online in JAMA Internal Medicine (formerly Archives of Internal Medicine) on February 18. For the study, 41 patients with ICDs and 11 cardiologists ...
