Most electronic games are no better than watching TV in terms of the body movement and energy expenditure involved, say the authors. Kids in developed countries spend an estimated 38 to 90 minutes a day playing these games. But what has not been clear is whether the newer generation "active" games, such as Sony PlayStation EyeToy and Move, dance mats, and Microsoft Xbox Kinect, are any better. The Australian researchers compared the impact of removing traditional electronic games, involving a game pad, from the home or replacing them with more active newer generation ...

One in five UK NHS staff report bullying by colleagues, with almost half saying they have witnessed bullying, in the past six months, indicates research published in the online journal BMJ Open. Managers are the most common source of bullying, with workload pressures and organisational culture contributory factors, the study reveals. The findings are based on the responses of almost 3000 NHS staff (46% response rate) to a validated questionnaire (NAQ-R), designed to tease out exposure to negative and bullying behaviours. The 12 item General Health Questionnaire (GHQ-12) ...

Shift work has been suggested as a risk factor for breast cancer, but there has been some doubt about the strength of the findings, largely because of issues around the assessment of exposure and the failure to capture the diversity of shift work patterns. Several previous studies have also been confined to nurses rather than the general population. In this study, the researchers assessed whether night shifts were linked to an increased risk of breast cancer among 1134 women with breast cancer and 1179 women without the disease, but of the same age, in Vancouver, British ...

Previously misunderstood multi-sensory organs in the skin of crocodylians are sensitive to touch, heat, cold, and the chemicals in their environment, finds research in BioMed Central's open access journal EvoDevo. These sensors have no equivalent in any other vertebrate. Crocodylians, the group that includes crocodiles, gharials, alligators and caimans, have particularly tough epidermal scales consisting of keratin and bony plates for added protection. On the head, these scales are unusual because they result from cracking of the hardened skin, rather than their shape ...

People with tuberculosis (TB) in China often delay going to see a doctor for more than two weeks, finds research in BioMed Central's open access journal BMC Medicine. Reasons for this include a poor understanding of TB, increasing costs of treatment not covered by health insurance, and using traditional approaches first. Even after going to a clinic there were still delays in treatment, especially in rural areas, due to a lack of qualified medical staff. Worldwide TB remains a leading cause of death, and China has the second largest TB epidemic with the most number of ...

Implementing an out-of hospital stroke policy in some Chicago hospitals was associated with significant improvements in emergency medical services use and increased intravenous tissue plasminogen activator (tPA) use at primary stroke centers, according to a study published by JAMA Neurology. The study evaluated the relationship between a citywide policy recommending pre-hospital triage of patients with suspected stroke to transport them to the nearest primary stroke center and use of intravenous tPA use. The therapy is used to restore blood flow through blocked arteries ...

It identifies the Amazon region, the Mediterranean and East Africa as regions that might experience severe change in multiple sectors. The article is part of the outcome of the Intersectoral Impact Model Intercomparison Project (ISI-MIP) that will be featured in a special issue of PNAS later this year. "Overlapping impacts of climate change in different sectors have the potential to interact and thus multiply pressure on the livelihoods of people in the affected regions," says lead-author Franziska Piontek of the Potsdam Institute for Climate Impact Research. "This is ...

PITTSBURGH, July 1, 2013 – Cells of the placenta may have a unique ability to prevent viruses from crossing from an expectant mother to her growing baby and can transfer that trait to other kinds of cells, according to researchers at Magee-Womens Research Institute (MWRI) and the University of Pittsburgh School of Medicine. Their findings, published in the early online version of the Proceedings of the National Academy of Sciences, shed new light on the workings of the placenta and could point to new approaches to combat viral infections during pregnancy. It is imperative ...

When it comes to economics versus psychology, score one for psychology. Economists argue that markets usually reflect rational behavior—that is, the dominant players in a market, such as the hedge-fund managers who make billions of dollars' worth of trades, almost always make well-informed and objective decisions. Psychologists, on the other hand, say that markets are not immune from human irrationality, whether that irrationality is due to optimism, fear, greed, or other forces. Now, a new analysis published in the XX issue of the Proceedings of the National Academy ...

In order to extend forecasting from six months to one year or even more, scientists have now proposed a novel approach based on advanced connectivity analysis applied to the climate system. The scheme builds on high-quality data of air temperatures and clearly outperforms existing methods. The study will be published this week in the Proceedings of the National Academy of Sciences. "Enhancing the preparedness of people in the affected regions by providing more early-warning time is key to avoiding some of the worst effects of El Niño," says Hans Joachim Schellnhuber, ...

A new technique that involves removing the nerves connecting the kidney to the brain has shown to significantly reduce blood pressure and help lower the risk of stroke, heart and renal disease in patients. The procedure, which has very few side effects, has already shown promising results in hard-to-treat cases of high blood pressure. The technique, published in the journal Hypertension, was performed by a team led by Professor Julian Paton at the University of Bristol who found that in an animal model of hypertension removing nerves connecting the kidney to the brain ...

ANN ARBOR—A University of Michigan researcher and colleagues at the University of Georgia and elsewhere have identified the most underfunded countries in the world for biodiversity conservation. They found that 40 of the most poorly funded countries harbor 32 percent of all threatened mammalian biodiversity. Most—though not all—of the countries in greatest need of more funding are developing nations, so important gains could be made at relatively low cost, the researchers concluded. "Knowing where the need is greatest could help aid donors to direct their funding for ...

The first evidence of widespread 'modern slavery' in England for refugees and asylum seekers is revealed in a study published today. The two-year study calls for an overhaul of government policy to restore asylum seekers' right to work and ensure all workers can access basic employment rights, such as National Minimum Wage, irrespective of immigration status. Dr Stuart Hodkinson from the University of Leeds, who co-authored of the study, said: "We found that in the majority of cases, if the asylum seeker had been able to work legally then the employer or agent would ...

HOUSTON – (July 1, 2013) – The idea that worms can be seen as waveforms allowed scientists at Rice University to find new links in gene networks that control movement. The work led by Rice biochemist Weiwei Zhong, which will appear online this week in the Proceedings of the National Academy of Sciences Early Edition, involved analyzing video records of the movement of thousands of mutant worms of the species Caenorhabditis elegans to identify the neuronal pathways that drive locomotion. One result was the discovery of 87 genes that, when inactivated, caused movement ...

Washington, DC, July 1, 2013 – Pregnant women with diabetes are more than three times as likely as mothers without diabetes to become infected with methicillin-resistant Staphylococcus aureus (MRSA) before hospital discharge, according to a study in the July issue of the American Journal of Infection Control, the official publication of the Association for Professionals in Infection Control and Epidemiology (APIC). The study aim was to investigate the extent to which pre-pregnancy and gestational diabetes are associated with MRSA infection. Researchers found that pre-pregnancy ...

System 96E became a tropical depression and quickly grew into Tropical Storm Dalila on June 30. Dalila has been hugging the coast of southwestern Mexico practically since it formed, and continues to do so on satellite imagery taken on July 1.Because of its close proximity to the coast, there's a tropical storm warning in effect for the southwestern coast of Mexico from Punta San Telmo to La Fortuna, and a Tropical Storm Watch from north of La Fortuna. That means 1 to 3 inches of rainfall expected over coastal areas of the Mexican states of Micohcan, Colima and Jaliso, and ...

There are currently 27 fires in the northeast section of Manitoba. These fires have burned over 126,000 hectares (over 311,000 acres). Showers have lowered wildfire danger levels in most areas of the province with the exception of northeastern Manitoba where conditions continue to remain dry. The hot temperatures forecasted through this coming weekend will dry forested areas and increase these danger levels. The fire weather forecast for this area is for fast-spreading, high-intensity crown fire that is very difficult to control. This natural-color satellite image was ...

(Lebanon, NH, 6/26/13) —The rapid increase in papillary thyroid cancer in the US, may not be linked to increase in occurrence, according to a head and neck surgeon at Dartmouth-Hitchcock Norris Cotton Cancer Center, instead it may be linked to an increase in the diagnosis of pre-cancerous conditions and to a person's insurance status. That is the conclusion of a paper published in Thyroid, a peer reviewed journal of the American Thyroid Association, which included the research of Senior Author Louise Davies, MD, MS, The Veteran's Administration Outcomes Group, White River ...

Researchers at UCLA's Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research have successfully established the foundation for using hematopoietic (blood-producing) stem cells from the bone marrow of patients with sickle cell disease to treat the disease. The study was led by Dr. Donald Kohn, professor of pediatrics and of microbiology, immunology and molecular genetics. Sickle cell disease causes the body to produce red blood cells that are formed like the crescent-shaped blade of a sickle, which hinders blood flow in the blood vessels and deprives ...

New Rochelle, NY, July 1, 2013—Among the increasingly valuable roles fungi are playing in the biotechnology industry is their ability to produce enzymes capable of releasing sugars from plants, trees, and other forms of complex biomass, which can then be converted to biofuels and biobased chemicals. Advances in fungal biology and in bioengineering fungal systems industrial applications are explored in a series of articles in Industrial Biotechnology, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The articles are available on the Industrial Biotechnology ...

DENVER – Personalized medicine in lung cancer relies on the identification and characterization of cancer biomarkers and the availability of accurate detection systems and therapies for those biomarkers. The standard procedure for detection of predictive anaplastic lymphoma kinase (ALK)-rearrangements is fluorescence in situ hybridization (FISH), but FISH is both expensive and often challenging to interpret. Lung cancer is often diagnosed by cytology necessitating predictive molecular marker analyses on cytological specimens. Now research published in the August issue ...

DENVER – The implementation of personalized health care in cancer relies on the identification and characterization of cancer biomarkers and the availability of accurate detection systems and therapies for those biomarkers. Anaplastic lymphoma kinase (ALK), a tyrosine kinase, is a more recently characterized cancer biomarker in non–small-cell lung cancer (NSCLC). To identify NSCLC patients with ALK gene rearrangement in clinical trials, researchers have used the methods known as fluorescence in situ hybridization (FISH) or immunohistochemistry (IHC). While IHC is a less ...

DENVER – Stereotactic body radiotherapy (SBRT) is considered the treatment of choice for early-stage non–small-cell lung cancer (NSCLC) if patients are inoperable because of additional medical conditions. This is based on several prospective phase II trials, which reported consistently high rates of local tumor control. However, these studies only included small number of patients, the methodology of SBRT varied between the studies and SBRT was mainly practiced in specialized centers. Therefore, safety and efficacy of SBRT practiced in routine clinical practice outside ...

The Silver Fire in southern New Mexico continues to generate a lot of smoke, as seen recently on imagery from NASA's Terra satellite. The Silver Fire is burning in the Gila National Forest. As of July 1, the fire had consumed 133,625 acres. It began on June 7 from a lightning strike near Kingston, New Mexico. According to the multi-agency Incident Information System called Inciweb, the fire was 50 percent contained on July 1. The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard NASA's Terra satellite has infrared capabilities that can detect ...

Physicians with the Society for Maternal-Fetal Medicine released a paper today that provides significant insight into future health conditions that women are likely to experience, and that can be detected early based on information relating to the course of pregnancy. The paper, Pregnancy as a Window to Future Health: The development of complications in pregnancy provides a new window of opportunity for early heart disease risk screening and intervention for women, acknowledges that, for most women, the demands of pregnancy on the cardiovascular and metabolic systems are ...
