Infants exposed to specific molds have higher asthma risk

2012-08-02
CINCINNATI—In the United States, one in 10 children suffers from asthma but the potential environmental factors contributing to the disease are not well known. Cincinnati-based researchers now report new evidence that exposure to three types of mold during infancy may have a direct link to asthma development during childhood. These forms of mold—Aspergillus ochraceus, Aspergillus unguis and Penicillium variabile—are typically found growing in water-damaged homes, putting a spotlight on the importance of mold remediation for public health. Lead author Tiina Reponen, ...

Chronic vulvar pain related to irritable bowel syndrome, fibromyalgia and interstitial cystitis

2012-08-02
ANN ARBOR, Mich. — Millions of women suffer from unexplained vulvar pain so severe it can make intercourse, exercise and even sitting unbearable. New research now shows that women with this painful vaginal condition known as vulvodynia are two to three times more likely to also have one or more other chronic pain conditions, including irritable bowel syndrome, fibromyalgia (musculoskeletal pain) and interstitial cystitis (bladder pain). These increasingly prevalent chronic pain conditions are known to be underdiagnosed – and the new data sheds more light on how they ...

Disorders of consciousness: How should clinicians respond to new therapeutic interventions?

2012-08-02
New tools have confirmed high rates of misdiagnosis of patients with chronic disorders of consciousness, such as the vegetative state. An increasing number of patients' families wish to use these novel techniques for diagnosis, prognosis, and treatment. An international team of researchers, including Dr. Éric Racine, researcher at the IRCM, analyzed the clinical, social and ethical issues that clinicians are now facing. Their article is published in the August edition of The Lancet Neurology, a renowned journal in the field of clinical neurology. "Patients with disorders ...

What sets allergies in motion?

2012-08-02
Allergies, or hypersensitivities of the immune system, are more common than ever before. According to the Asthma and Allergies Foundation of America, one in five Americans suffers from an allergy — from milder forms like hay fever to more severe instances, like peanut allergies which can lead to anaphylactic shock. While medications like antihistamines can treat the symptoms of an allergic reaction, the treatment is too limited, says Prof. Ronit Sagi-Eisenberg, a cell biologist at Tel Aviv University's Sackler Faculty of Medicine. Cells release dozens of molecules during ...

Multiple husbands serve as child support and life insurance in some cultures says MU researcher

2012-08-02
Marrying multiple husbands at the same time, or polyandry, creates a safety net for women in some cultures, according to a recent study by a University of Missouri researcher. Extra husbands ensure that women's children are cared for even if their fathers die or disappear. Although polyandry is taboo and illegal in the United States, certain legal structures, such as child support payments and life insurance, fill the same role for American women that multiple husbands do in other cultures. "In America, we don't meet many of the criteria that tend to define polyandrous ...

Early relationships, not brainpower, key to adult happiness

2012-08-02
Positive social relationships in childhood and adolescence are key to adult well-being, according to Associate Professor Craig Olsson from Deakin University and the Murdoch Children's Research Institute in Australia, and his colleagues. In contrast, academic achievement appears to have little effect on adult well-being. The exploratory work, looking at the child and adolescent origins of well-being in adulthood, is published online in Springer's Journal of Happiness Studies. We know very little about how aspects of childhood and adolescent development, such as academic ...

Researcher's fish-eye view could offer insights for human vision

Researchers fish-eye view could offer insights for human vision
2012-08-02
August 2, 2012 WEST LAFAYETTE, Ind. - A Purdue University student's research project related to zebrafish eye development could lead to a better understanding of vision problems that affect billions of people worldwide. Zeran Li, as an undergraduate student in biological sciences, led a research team that uncovered an enzyme's role in the regulation of eye size in the fish. If the enzyme's role is similar in human eyes, it could be relevant to human vision problems, such as nearsightedness and farsightedness. "New insights into the process of eye-size control in zebrafish ...

Studying couples to improve health, better relationships

2012-08-02
August 2, 2012 - It is not always best to forgive and forget in marriage, according to new research that looks at the costs of forgiveness. Sometimes expressing anger might be necessary to resolve a relationship problem – with the short-term discomfort of an angry but honest conversation benefiting the health of the relationship in the long-term. The research is part of a larger effort to better understand the contexts in which some relationships succeed and others fail, and also to understand how close relationships affect our health. A popular research trend in recent ...

Timing of antibiotics important in reducing infections after C-section

2012-08-02
Giving antibiotics before cesarean section surgery rather than just after the newborn's umbilical cord is clamped cuts the infection rate at the surgical site in half, according to researchers at Washington University School of Medicine in St. Louis and Barnes-Jewish Hospital. "We followed more than 8,000 women over an eight-year period, and our findings support giving antibiotics just before a cesarean section to prevent infections," says infectious disease specialist David K. Warren, MD. "Until recently, standard practice in the U.S. was to give antibiotics when the ...

Fingering the culprit that polluted the Solar System

2012-08-02
Washington, D.C. — For decades it has been thought that a shock wave from a supernova explosion triggered the formation of our Solar System. According to this theory, the shock wave also injected material from the exploding star into a cloud of dust and gas, and the newly polluted cloud collapsed to form the Sun and its surrounding planets. New work from Carnegie's Alan Boss and Sandra Keiser provides the first fully three-dimensional (3-D) models for how this process could have happened. Their work will be published by The Astrophysical Journal Letters. Traces of the ...

Students trading sex for drugs or alcohol happens also in rural B.C.: UBC research

2012-08-02
Just over two percent of teens in rural schools who have ever tried alcohol, marijuana or other drugs report they have also traded sex for these substances, according to University of British Columbia research published today in the Canadian Journal of Human Sexuality. This is the first study to track this issue among rural students. Using 2009 survey data from 2,360 students in Grades 7-12 from 28 schools in B.C.'s East Kootenays, the researchers found equal numbers of boys and girls traded sex, and that up to 98 per cent of them were living at home with family. Conducted ...

UCSB autism researchers find that focusing on strengths improves social skills of adolescents

UCSB autism researchers find that focusing on strengths improves social skills of adolescents
2012-08-02
(Santa Barbara, Calif.) –– The junior high and high school years are emotionally challenging even under the best of circumstances, but for adolescents with autism spectrum disorders (ASD), that time can be particularly painful. Lacking the social skills that enable them to interact successfully with their peers, these students are often ostracized and even bullied by their classmates. However, a new study conducted by researchers at the Koegel Autism Center at UC Santa Barbara has found that by playing on their strengths –– high intelligence and very specific interests ...

The aging brain is more malleable than previously believed

2012-08-02
There is growing evidence that, beyond what was previously believed, the adult human brain is remarkably malleable and capable of new feats -- even in the last decades of life. In fact, new experiences can trigger major physical changes in the brain within just a few days, and certain conditions can accelerate this physical, chemical and functional remodeling of the brain. "We used to think that the brain was completely formed by development and its basic structure didn't change much in adults, but as research went on we discovered that wasn't true, at least in the ...

Recurring shoulder instability injuries likely among young athletes playing contact sports

2012-08-02
Summer is a peak season for many sports, and with that comes sport-related injuries. Among those injuries is shoulder joint dislocation. According to a literature review in the August 2012 issue of the Journal of the American Academy of Orthopaedic Surgeons, most incidences of shoulder joint instability are the result of traumatic contact injuries like force or falling on an outstretched arm; a direct blow to the shoulder area; forceful throwing, lifting or hitting; or contact with another player. By the Numbers In 45 percent of shoulder joint instability injuries, ...

New study by Syracuse University scientists uncovers a reproduction conundrum

2012-08-02
When it comes to sperm meeting eggs in sexual reproduction, conventional wisdom holds that the fastest swimming sperm are most likely to succeed in their quest to fertilize eggs. That wisdom was turned upside down in a new study of sperm competition in fruit flies (Drosophila melanogaster), which found that slower and/or longer sperm outcompete their faster rivals. The study, recently published online in Current Biology and forthcoming in print on Sept. 25, was done by a team of scientists led by corresponding author Stefan Lüpold, a post-doctoral researcher in the Department ...

Learning machines scour Twitter in service of bullying research

2012-08-02
MADISON — Hundreds of millions of daily posts on the social networking service Twitter are providing a new window into bullying — a tough nut to crack for researchers. "Kids are pretty savvy about keeping bullying outside of adult supervision, and bullying victims are very reluctant to tell adults about it happening to them for a host of reasons," says Amy Bellmore, a University of Wisconsin–Madison educational psychology professor. "They don't want to look like a tattletale, or they think an adult might not do anything about it." Yet typical bullying research methods ...

A diet high in choline during pregnancy may mean less stress for baby

2012-08-02
Park Ridge, Ill. (August 1, 2012) – New research from Cornell University indicates that pregnant women who increase choline intake in the third trimester of pregnancy may reduce the risk of the baby developing metabolic and chronic stress-related diseases like high blood pressure and diabetes later in life.(i) The results, published in the latest edition of the Journal of the Federation of American Societies for Experimental Biology, suggest that choline, a nutrient found in high quantities in eggs, may help protect against the effects of a mother's stress during pregnancy. ...

Who influences your vote? It may depend on how soon the election is

2012-08-02
Neighbors' lawn signs, public opinion polls and even a conversation in the next restaurant booth can affect how people vote in an election. But it all depends on how far away the election is. In a new research article published in Psychological Science, a journal of the Association for Psychological Science, scientists Alison Ledgerwood and Shannon Callahan of the University of California, Davis conducted two different studies examining the relationship between abstract thinking and group norms people's support for different policies. In the first study, they asked ...

Massive data for miniscule communities

2012-08-02
EAST LANSING, Mich. — It's relatively easy to collect massive amounts of data on microbes. But the files are so large that it takes days to simply transmit them to other researchers and months to analyze once they are received. Researchers at Michigan State University have developed a new computational technique, featured in the current issue of the Proceedings of the National Academy of Sciences, that relieves the logjam that these "big data" issues create. Microbial communities living in soil or the ocean are quite complicated. Their genomic data is easy enough to ...

Early weaning, DDGS feed could cut costs for cattle producers

Early weaning, DDGS feed could cut costs for cattle producers
2012-08-02
WEST LAFAYETTE, Ind. - If the drought forces producers to feed a larger portion of distillers dried grains with solubles, cattle can maintain gains and improve meat quality if the animals are weaned early, a Purdue University scientist has shown. The finding, reported at the American Society of Animal Science Midwest Meetings in Des Moines, Iowa, could allow some producers to save on rising feed costs in the face of this year's drought. Distillers dried grains with solubles, or DDGS, are the leftovers from corn ethanol production. DDGS generally cost about 10 percent ...

Brain imaging can predict how intelligent you are, study finds

Brain imaging can predict how intelligent you are, study finds
2012-08-02
When it comes to intelligence, what factors distinguish the brains of the exceptionally smart from those of average humans? As science has long suspected, overall brain size matters somewhat, accounting for about 6.7 percent of individual variation in intelligence. More recent research has pinpointed the brain's lateral prefrontal cortex, a region just behind the temple, as a critical hub for high-level mental processing, with activity levels there predicting another 5 percent of variation in individual intelligence. Now, new research from Washington University in St. ...

Adolescents' personalities and coping habits affect social behaviors, MU researcher says

2012-08-02
COLUMBIA, Mo. – Infants innately relieve stress by crying, turning their heads or maintaining eye contact. Adults manage emotional tension using problem-solving or by seeking support. A new study by a University of Missouri human development expert describes how adolescents' developing personalities and coping habits affect their behaviors toward others. "We're each born with some personality tendencies; for example, we see that babies are fussy or calm," said Gustavo Carlo, the Millsap Professor of Diversity in the MU Department of Human Development and Family Studies. ...

Breaking the barriers for low-cost energy storage

2012-08-02
A team of researchers has developed a cheap, rechargeable and eco-friendly battery that could be used to store energy at solar power plants for a rainy day. Led by Sri Narayan, professor of chemistry at the USC Dornsife College of Letters, Arts and Sciences, the team developed an air-breathing battery that uses the chemical energy generated by the oxidation of iron plates that are exposed to the oxygen in the air – a process similar to rusting. "Iron is cheap and air is free," Narayan said. "It's the future." Details about the battery will be published July 20 in the ...

Molecular switch identified that controls key cellular process

2012-08-02
New York, NY and Oxford, UK, August 1, 2012 – The body has a built-in system known as autophagy, or 'self-eating,' that controls how cells live or die. Deregulation of autophagy is linked to the development of human diseases, including neural degeneration and cancer. In a study published online this week in the Proceedings of the National Academy of Sciences, scientists at the Ludwig Institute for Cancer Research in Oxford discovered a critical molecular switch that regulates autophagy. They also studied the links between autophagy and a cellular process called senescence ...
