CHICAGO -- Why do unmarried women tend to be more liberal and Democratic than their married counterparts? A key reason is because unmarried women -- those who have never been married and those who are divorced -- are more concerned about the status of women as a collective group, suggests a new study that will be presented at the 110th Annual Meeting of the American Sociological Association (ASA). "Over 67 percent of never married women and 66 percent of divorced women perceive what happens to other women as having some or a lot to do with what happens in their own ...

CHICAGO -- For American women, a book club membership means more than having status as a reader, as it might pay dividends to them in the dating field as well. A University of Kansas (KU) researcher as part of a study on gendered sexuality compared women's book clubs in Colorado and Ireland and made the finding regarding how the women in each country used the role of reading in romantic relationships. "American women utilized their status as readers and book club members to increase their popularity in the dating field and explained that they would never date or marry ...

CHICAGO -- As supporters and opponents of the proposed Keystone XL (KXL) Pipeline testified at public hearings in Nebraska between 2010-2013, several interest groups attempted to frame the debate in different ways. A University of Kansas (KU) researcher who examined 528 testimonies from public hearings in Nebraska said the debate boiled down to a confrontation between stakeholders in two types of natural resources: water from the Oglala Aquifer and bitumen extracted from Alberta, Canada. "It's not a battle between these two resources, but the cultural values people ...

Two-year-old children with larger oral vocabularies enter U.S. kindergarten classrooms better at reading and mathematics as well as better behaved, according to a team of researchers lead by Paul Morgan, associate professor of education policy studies, Penn State. Other research has found that children who are doing better academically in kindergarten are more likely to go to college, get married, own homes and live in higher-income households. "Our findings provide compelling evidence for oral vocabulary's theorized importance as a multifaceted contributor to children's ...

ALLENDALE, Mich. -- New research released by professors from Grand Valley State University and Stanford University reveals most social surveys in the U.S. are not measuring what surveyors think is being measured in regard to sex and gender. "The way that surveys have historically measured sex and gender and how they still continue to do so does not align with current gender theory or lived experiences," said Laurel Westbrook, associate professor of sociology at Grand Valley and co-author of the study. "While gender theorists see sex and gender as separate concepts, surveys ...

Leaves of the European chestnut tree contain ingredients with the power to disarm dangerous staph bacteria without boosting its drug resistance, scientists have found. PLOS ONE is publishing the study of a chestnut leaf extract, rich in ursene and oleanene derivatives, that blocks Staphlococcus aureus virulence and pathogenesis without detectable resistance. The use of chestnut leaves in traditional folk remedies inspired the research, led by Cassandra Quave, an ethnobotanist at Emory University. "We've identified a family of compounds from this plant that have an ...

WASHINGTON (August 24, 2015) -- Obese atrial fibrillation patients have a lower chance of arrhythmia recurrence if they have high levels of cardiorespiratory fitness, and risk continues to decline as exercise capacity increases as part of treatment, according to a study published today in the Journal of the American College of Cardiology. Cardiorespiratory fitness gain provides an incremental gain over weight loss in long-term freedom from arrhythmia. "While weight loss is important for heart disease patients, especially those with arrhythmia, our study shows it's ...

DARIEN, IL - A new study clearly establishes a partial genetic basis underlying racial differences in slow-wave sleep, suggesting that it may be possible to develop sleep-related therapies that target specific genetic variants. Using a panel of 1,698 ancestry informative genetic markers, the study found that greater African genetic ancestry was associated with lower amounts of slow-wave sleep in African-American adults. African ancestry explained 11 percent of the variation in slow-wave sleep after adjustment for potential confounders. Although a similar association was ...

Since its discovery, graphene has captured the attention of scientists and engineers for its many extraordinary properties. But graphene oxide -- an oxidized derivative of graphene -- largely has been viewed as graphene's inferior cousin. "Graphene is so perfect," said Northwestern Engineering's Jiaxing Huang. "And graphene oxide is more defective, so it's like the weaker, less exciting version of graphene." Now a Northwestern University team has found that graphene oxide's seemingly undesirable defects surprisingly give rise to exciting mechanical properties. Led by ...

From the spinning disc of a computer's hard drive to the varying current in a transformer, many technological devices work by merging electricity and magnetism. But the search to find a single material that combines both electric polarizations and magnetizations remains challenging. This elusive class of materials is called multiferroics, which combine two or more primary ferroic properties. Northwestern University's James Rondinelli and his research team are interested in combining ferromagnetism and ferroelectricity, which rarely coexist in one material at room temperature. "Researchers ...

A review of survey data from more than 300 obese people who participated in a federally funded weight loss clinical trial found that although the overall weight loss rates were modest, those who rated their primary care doctor's support as particularly helpful lost about twice as many pounds as those who didn't. In a report on the study by Johns Hopkins researchers, published in the Aug. 21 issue of Patient Education and Counseling, the researchers say the findings could inform the development of weight loss programs that give primary care physicians a starring role. Researchers ...

A recently-published study found that while internal bleeding may be uncommon as a result of taking blood thinners such as Xarelto® (rivaroxaban) and Eliquis® (apixaban), the normal coagulation tests physicians use to check for the side effect of bleeding may not be reliable. The study, published online in Annals of Emergency Medicine, found that in cases reported to Poison Centers, the routine labs used to monitor for clotting factors, such as prothrombin time (PT), PTT or INR commonly ordered to help diagnose internal bleeding may be elevated in a minority of ...

Astronauts aboard the International Space Station captured an image of Hurricane Danny moving through the Central Atlantic Ocean. Satellite data indicates that Danny is a small Category 2 hurricane, in which hurricane-force winds only extend 15 miles from the eye. A NASA GOES Project animation of visible and infrared imagery of Hurricane Danny was created at NASA's Goddard Space Flight Center in Greenbelt, Maryland to show the development and movement of the storm. The animation shows the eastern and central Atlantic Ocean from Aug. 18 to 21, 2015. Forecaster Cangialosi ...

"Flocking" or "swarming" behavior is omnipresent in the living world, observed in birds, fish, and even bacteria. Strikingly similar collective action can also be seen in biomolecules within and between cells. Such self-organization processes are the basis of life - without them no living cell would exist - yet they are not well understood. New insights into how this action is coordinated at the biomolecular level are emerging from studies of a model system based on actin filaments. Experimental evidence proves the inadequacy of widely accepted explanations, according to ...

AMHERST, Mass. - Inspired by natural "snapping" systems like Venus flytrap leaves and hummingbird beaks, a team led by physicist Christian Santangelo at the University of Massachusetts Amherst has developed a way to use curved creases to give thin curved shells a fast, programmable snapping motion. The new technique avoids the need for complicated materials and fabrication methods when creating structures with fast dynamics. The advance should help materials scientists and engineers who wish to design structures that can rapidly switch shape and properties, says Santangelo. ...

ANN ARBOR--People who have not found their perfect fit in a career can take heart: There is more than one way to attain passion for work. Contrary to popular wisdom, a love-at first-sight experience is not necessary when evaluating a potential job, according to a new University of Michigan study. "The good news is that we can choose to change our beliefs or strategies to cultivate passion gradually or seek compatibility from the outset, and be just as effective in the long run at achieving this coveted experience," said Patricia Chen, a doctoral psychology student and ...

Researchers from North Carolina State University and the University of North Carolina at Chapel Hill have discovered how two important proofreader proteins know where to look for errors during DNA replication and how they work together to signal the body's repair mechanism. When a cell prepares to divide, the DNA splits first, the double helix "unzipping" into two separate backbones. New nucleotides - adenine, cytosine, guanine or thymine - are filled into the gaps on the other side of the backbone, pairing with their counterparts (adenine with thymine and cytosine with ...

In human cells, shortened telomeres, the protective caps at the ends of chromosomes, are both a sign of aging and contribute to it. Scientists at Emory University School of Medicine have found that the dietary supplement alpha lipoic acid (ALA) can stimulate telomerase, the enzyme that lengthens telomeres, with positive effects in a mouse model of atherosclerosis. The discovery highlights a potential avenue for the treatment for chronic diseases. The results were published Thursday, August 20 in Cell Reports. "Alpha-lipoic acid has an essential role in mitochondria, ...

(Boston)--Poor sleep may impact treatment and recovery in veterans with Post-Traumatic Stress Disorder (PTSD) and Traumatic Brain Injury (TBI). A review of extensive research on sleep in TBI and PTSD has found that sleep-focused interventions can improve treatment outcomes in veterans. Led by researchers at Boston University School of Medicine (BUSM) and VA Boston Healthcare System, the review article currently appears online in the journal of Clinical Psychology Review. Sleep difficulty is a primary symptom of both PTSD and TBI and has been found to affect the severity ...

People who fear relationship conflicts are just as happy when they are single or in a relationship, according to new research published by the Society for Personality and Social Psychology. "It's a well-documented finding that single people tend to be less happy compared to those in a relationship, but that may not be true for everyone. Single people also can have satisfying lives," said lead researcher Yuthika Girme, a psychology doctoral candidate at the University of Auckland in New Zealand. In a survey of more than 4,000 New Zealand residents, a nationally ...

Water pollution has been a historical and stubborn problem in the water resource management. Several water pollution accidents continually occurred all over the world, threatening the safety of industry, agriculture and drinking water for resident's life (see Figure 1). An innovative and efficient approach was identified to study the complicated mechanism of water pollution in alluvial rivers. The article titled "Numerical Simulation of Pollution Process Due to Resuspension of Bed Materials Adsorbing Pollutants in Alluvial Rivers" was recently published in Science China ...

Researchers at the University of Strathclyde are developing groundbreaking plasma based light amplifiers that could replace traditional high power laser amplifiers. The research group at the Glasgow-based University are leading efforts to take advantage of plasma, the ubiquitous medium that makes up most of the universe, to make the significant scientific breakthrough. The next generation of high power lasers should be able to crack the vacuum to produce real particles from the sea of virtual particles. Example of these types of lasers can be found at the Extreme Light ...

New research by European and African scientists, including a team from the University of York, warns of the risks posed by the increasing air pollution over the cities of West Africa - amid fears it could have an impact on human health, meteorology and regional climate. The atmosphere above West Africa is still one of the least studied and understood on the planet, despite its central role for the health and economic wellbeing of a large and increasing population. Rapidly expanding cities such as Lagos in Nigeria, Accra in Ghana and Abidjan in Ivory Coast are producing ...

More than a quarter of a million people die each year from using smokeless tobacco, researchers at the University of York have concluded. Millions more have their lives shortened by ill health due to the effects of chewing tobacco-based products, the study reveals. Researchers say it is the first time the global impact of smokeless tobacco consumption on adults has been assessed. The team, which included collaboration from the University of Edinburgh and Imperial College, London, says governments and public health bodies need to consider incorporating the regulation ...

The quality of general family functioning is a major determinant of healthy dietary habits - according to new research published in the Journal of Caries Research and led by Queen Mary University of London. The East London Family (ELF) Study found that a mother's perception of effective general family functioning has a significant effect on limiting the intake of sugary foods and drinks by their three and four year old children. In contrast, less effective family functioning leads to high frequency intake of sugary foods and drinks by three and four year old children ...
