Women's health and Fifty Shades: Increased risks for young adult readers?
2014-08-21
New Rochelle, NY, August 21, 2014—Popular fiction that normalizes and glamorizes violence against women, such as the blockbuster Fifty Shades series, may be associated with a greater risk of potentially harmful health behaviors and risks. The results of a provocative new study are presented in the article "Fiction or Not? Fifty Shades Is Associated with Health Risks in Adolescent and Young Adult Females," published in Journal of Women's Health, a peer-reviewed publication from Mary Ann Liebert, Inc., publishers. The article is available free on the Journal of Women's Health ...
AAAS: Sri Lanka images show no significant increase in public facilities, despite promises
2014-08-21
Thousands of Sri Lankans remain refugees five years after a long civil war, and satellite-image analysis seems to reveal many new housing-like structures and development in a military zone in the northern part of the country. However, the analysis also shows no significant increase in civic facilities despite government claims that it has seized the land for public use.
The analysis, completed by the nonprofit, nonpartisan American Association for the Advancement of Science (AAAS), suggests a sharp increase in the number of residential housing-type structures within the ...
Research offers insight into cellular biology of colorectal cancer
2014-08-21
LAWRENCE — A study recently published in the journal Carcinogenesis by researchers at the University of Kansas shows a new role for the protein adenomatous polyposis coli (APC) in suppressing colorectal cancer — the second-leading cause of cancer-related deaths in the U.S.
Lead author Kristi Neufeld, associate professor in the Department of Molecular Biosciences and co-leader of the Cancer Biology program at the KU Cancer Center, has spent the better part of her career trying to understand the various activities of APC, a protein whose functional loss is thought to initiate ...
Delivery by drone
2014-08-21
CAMBRIDGE, MA -- In the near future, the package that you ordered online may be deposited at your doorstep by a drone: Last December, online retailer Amazon announced plans to explore drone-based delivery, suggesting that fleets of flying robots might serve as autonomous messengers that shuttle packages to customers within 30 minutes of an order.
To ensure safe, timely, and accurate delivery, drones would need to deal with a degree of uncertainty in responding to factors such as high winds, sensor measurement errors, or drops in fuel. But such "what-if" planning typically ...
Conclusive evidence on role of circulating mesenchymal stem cells in organ injury
2014-08-21
New Rochelle, NY, August 21, 2014--Mesenchymal stem cells (MSCs) are present in virtually every type of human tissue and may help in organ regeneration after injury. But the theory that MSCs are released from the bone marrow into the blood stream following organ damage, and migrate to the site of injury, has long been debated. M.J. Hoogduijn and colleagues provide conclusive evidence to resolve the controversy over the mobilization and migration of MSCs in humans in a new study published in Stem Cells and Development, a peer-reviewed journal from Mary Ann Liebert, Inc., ...
The Lancet: Experimental Ebola drugs must be fairly distributed and tested ethically in clinical trials
2014-08-21
Researchers and health authorities need to ensure that experimental drugs to treat Ebola are distributed fairly, and in the context of randomized controlled trials, according to a new Viewpoint, published in The Lancet today [Thursday 21 August, 2014].
Leading bioethicists Professor Ezekiel Emanuel, of the University of Pennsylvania, Philadelphia, USA, and Dr Annette Rid, of King's College London, UK, outline critical ethical principles which need to be adhered to if experimental drugs are to be deployed in the Ebola outbreak, stating that the patients selected to receive ...
Polio: Mutated virus breaches vaccine protection
2014-08-21
Thanks to effective vaccination, polio is considered nearly eradicated. Each year only a few hundred people are stricken worldwide. However, scientists of the University of Bonn, together with colleagues from Gabon, are reporting alarming findings: a mutated virus that was able to resist the vaccine protection to a considerable extent was found in victims of an outbreak in the Congo in 2010. The pathogen could also potentially have infected many people in Germany. The results appear now in the magazine PNAS.
The polio epidemic in the Congo in 2010 was especially serious. ...
Mindfulness-based depression therapy reduces health care visits
2014-08-21
August 21, 2014 (Toronto) – A mindfulness-based therapy for depression has the added benefit of reducing health-care visits among patients who often see their family doctors, according to a new study by the Centre for Addiction and Mental Health (CAMH) and the Institute for Clinical Evaluative Sciences (ICES).
The research showed that frequent health service users who received mindfulness-based cognitive therapy showed a significant reduction in non-mental health care visits over a one-year period, compared with those who received other types of group therapy.

Given that more than 400 subglacial lakes and numerous rivers and streams are thought to ...
Arctic sea ice influenced force of the Gulf Stream
2014-08-21
For AWI geologist Juliane Müller the Fram Strait is a key region in the global oceanic circulation. "On the east side of this passage between Greenland and Svalbard warm Atlantic water flows to the north into the Arctic Ocean while on the west side cold Arctic water masses and sea ice push their way out of the Arctic into the North Atlantic. A considerable portion of the Atlantic water cools here on its way to the north and sinks to deeper layers. The circulation of the water caused in this manner drives the global band of oceanic currents like a giant pump and influences, ...
Water window imaging opportunity
2014-08-21
Ever heard of the water window? It consists of radiations in the 3.3 to 4.4 nanometre range, which are not absorbed by the water in biological tissues. New theoretical findings show that it is possible to develop coherent radiations within the water window. These could be the basis of an optimal technique to obtain a high-contrast image of the biological samples or to be used in high-precision spectroscopy. Now, a new theoretical study identifies the physical mechanism needed to efficiently generate the harmonic radiations—which are multiples of an incoming laser’s frequency—at ...

Tropical Storm Karina looks like a giant 'number 9' from space
2014-08-21
Despite being the eleventh tropical cyclone of the Eastern Pacific Ocean Hurricane Season, Karina looked like a giant number nine from NASA's Aqua satellite.
Tropical Storm Karina was weakening on August 20 when NASA's Terra satellite passed overhead. The Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard Terra snapped a visible image of Tropical Storm Karina on August 20 at 19:40 UTC (3:40 p.m. EDT). The MODIS image showed that a thick band of strong thunderstorms spiraled into Karina's center from the southeast. The band of thunderstorms wrapped ...
Insulin offers new hope for the treatment of acute pancreatitis
2014-08-21
Acute pancreatitis involves the pancreas digesting itself resulting in severe abdominal pain, vomiting and systemic inflammation. Every year in the UK around 20,000 patients are diagnosed with the disease resulting in 1000 deaths. There is no immediate cure and treatment is restricted to intravenous fluid and nutritional support.
Dr Jason Bruce, from the Faculty of Life Sciences, who led the research, said "The major causes of pancreatitis include bile acid reflux from gall stones and excessive alcohol intake combined with a high fat diet. In fact, the incidence of acute ...
Toothpaste fluorine formed in stars
2014-08-21
The fluorine that is found in products such as toothpaste was likely formed billions of years ago in now dead stars of the same type as our sun. This has been shown by astronomers at Lund University in Sweden, together with colleagues from Ireland and the USA.
Fluorine can be found in everyday products such as toothpaste and fluorine chewing gum. However, the origins of the chemical element have been somewhat of a mystery. There have been three main theories about where it was created. The findings now presented support the theory that fluorine is formed in stars similar ...
Researchers found an important clue to potential treatments for absence seizures
2014-08-21
Absence seizures are believed to be elicited by T-type calcium channels in the thalamic reticular nucleus of the brain that regulate influxes of calcium. These channels enable thalamic reticular nucleus neurons to generate burst firing, leading the neurons to enter a hyper-excited state.
In order to identify the relationship between burst firing and absence seizures, the researchers conducted an experiment to induce absence seizures in mice using gene targeting techniques to delete the T-type calcium channel CaV3.3. The results showed that mice that received a complete ...

Smartphone-loss anxiety disorder
2014-08-21
The smart phone has changed our behavior, sometimes for the better as we are now able to connect and engage with many more people than ever before, sometimes for the worse in that we may have become over-reliant on the connectivity with the outside world that these devices afford us. Either way, there is no going back for the majority of users who can almost instantaneously connect with hundreds if not thousands of people through the various social media and other applications available on such devices and not least through the humble phone call.
However, our dependence ...
ADHD children make poor decisions due to less differentiated learning processes
2014-08-21
Which shirt do we put on in the morning? Do we drive to work or take the train? From which takeaway joint do we want to buy lunch? We make hundreds of different decisions every day. Even if these often only have a minimal impact, it is extremely important for our long-term personal development to make decisions that are as optimal as possible. People with ADHD often find this difficult, however. They are known to make impulsive decisions, often choosing options which bring a prompt but smaller reward instead of making a choice that yields a greater reward later on down ...
Learning to play the piano? Sleep on it!
2014-08-21
According to researchers at the University of Montreal, the regions of the brain below the cortex play an important role as we train our bodies' movements and, critically, they interact more effectively after a night of sleep. While researchers knew that sleep helped us the learn sequences of movements (motor learning), it was not known why. "The subcortical regions are important in information consolidation, especially information linked to a motor memory trace. When consolidation level is measured after a period of sleep, the brain network of these areas functions with ...
Electric sparks may alter evolution of lunar soil
2014-08-21
DURHAM, N.H. –- The moon appears to be a tranquil place, but modeling done by University of New Hampshire and NASA scientists suggests that, over the eons, periodic storms of solar energetic particles may have significantly altered the properties of the soil in the moon's coldest craters through the process of sparking—a finding that could change our understanding of the evolution of planetary surfaces in the solar system.
The study, published recently in the Journal of Geophysical Research-Planets, proposes that high-energy particles from uncommon, large solar storms ...

Emergency department nurses aren't like the rest of us: New study
2014-08-21
Emergency department nurses aren't like the rest of us – they are more extroverted, agreeable and open – attributes that make them successful in the demanding, fast-paced and often stressful environment of an emergency department, according to a new study by University of Sydney.
"Emergency nurses are a special breed," says Belinda Kennedy from Sydney Nursing School, a 15 year critical care veteran who led the study.
"Despite numerous studies about personalities of nurses in general, there has been little research done on the personalities of nurses in clinical specialty ...
