New research suggests that promoting active play in children's leisure time could increase the physical activity of today's children, but that such strategies might need to be tailored according to gender. The paper, 'What is the meaning and nature of active play for today's children in the UK?' by Rowan Brockman and colleagues in the Centre for Exercise, Nutrition and Health Sciences within the School for Policy Studies at the University of Bristol, is published in the International Journal of Behavioral Nutrition and Physical Activity. The researchers found children's ...

Along with the excitement and anticipation that come with heading off to college, freshmen often find questions of belonging lurking in the background: Am I going to make friends? Are people going to respect me? Will I fit in? Those concerns are trickier for black students and others who are often stereotyped or outnumbered on college campuses. They have good reason to wonder whether they will belong – worries that can result in lower grades and a sense of alienation. But when black freshmen participated in an hour-long exercise designed by Stanford psychologists to ...

Plants are continually exposed to herbivore attack. To defend themselves, they have developed sophisticated chemical defense mechanisms. Plants of the mustard family, such as thale cress (Arabidopsis thaliana), produce glucosinolates (mustard oil glucosides) to protect themselves against herbivory. Scientists know many different kinds of these molecules; they have a similar structure, but different side chains. If insect larvae feed on mustard plants, glucosinolates are hydrolyzed to form toxic isothiocyanates. Chemists call this the "mustard oil bomb". Special enzymes ...

The Financial Express published an article on the Free Trade Agreement (FTA) talks that continue between the European Union (EU) and India. One of the most discussed and disagreed upon parts of the proposed FTA involves the need for protecting the intellectual property of pharmaceutical companies in order to promote medical innovation and investment in the development of new medicines and research. This disagreement about whether data exclusivity in the pharmaceutical sector should be included has resulted in the delay of finalizing the FTA. Pharmaceutical companies ...

In 2006, Maria Otilia Carvalho, a researcher from the Tropical Research Institute of Portugal had an ambitious goal: to cut the huge losses of rice – a staple food crop for half of humanity – due to pests, without using toxic pesticides that are increasingly shunned by consumers worldwide. She realised she could not do it alone and turned to EUREKA to support an international collaboration to address a looming threat to world's rice supplies. Harvested rice is constantly under menace from pest insects and fungi - to avoid the pests, farmers and producers treat the rice ...

The psychological impact of natural disasters such as the Japan earthquake can be revealed in the way people inherently respond to unpredictable situations, according to a psychology expert at Queen Mary, University of London. Dr Magda Osman, Psychology Lecturer at Queen Mary, University of London, and author of Controlling Uncertainty: Decision-making and Learning in Complex Worlds, said the disaster had a devastating immediate effect on tens of thousands of people in Japan but the true psychological impact will be felt "for some time to come". "A disaster like the ...

A new plant species is providing an insight into how evolution works and could help improve crop plants, scientists have revealed. The new plant species, Tragopogon miscellus, appeared in the United States 80 years ago. It came about when two species in the daisy family, introduced from Europe, mated to produce a hybrid offspring. The species had mated before in Europe, but the hybrids were never successful. However in America something new happened. The number of chromosomes in the hybrid spontaneously doubled, and at once it became larger than its parents and quickly ...

A study by the Complutense University of Madrid (UCM), analysing the impact of the labour reforms introduced over the past 30 years and the living conditions of new generations, asserts that these reforms have been the origin and cause of the current development model based on the exploitation of young people. "The study indicates that the Spanish economic development model over the past three decades – with high rates of economic growth and job creation – is based on the 'over-exploitation of the youngest generations of workers'", Pablo López Calle, author of the paper, ...

The tendency to perceive others as "us versus them" isn't exclusively human but appears to be shared by our primate cousins, a new study led by Yale researchers has found. In a series of ingenious experiments, Yale researchers led by psychologist Laurie Santos showed that monkeys treat individuals from outside their groups with the same suspicion and dislike as their human cousins tend to treat outsiders, suggesting that the roots of human intergroup conflict may be evolutionarily quite ancient. The findings are reported in the March issue of the Journal of Personality ...

Carbon nanofibers hold promise for technologies ranging from medical imaging devices to precise scientific measurement tools, but the time and expense associated with uniformly creating nanofibers of the correct size has been an obstacle – until now. A new study from North Carolina State University demonstrates an improved method for creating carbon nanofibers of specific sizes, as well as explaining the science behind the method. "Carbon nanofibers have a host of potential applications, but their utility is affected by their diameter – and controlling the diameter of ...

MIAMI – March 17, 2010 -- University of Miami (UM) Rosenstiel School of Marine & Atmospheric Science scientist Chris Langdon and colleagues developed a new tool to monitor coral reef vital signs. By accurately measuring their biological pulse, scientists can better assess how climate change and other ecological threats impact coral reef health worldwide. During a March 2009 experiment at Cayo Enrique Reef in Puerto Rico, the team tested two new methods to monitor biological productivity. They compared a technique that measures changes in dissolved oxygen within ...

Using skin cells from adult siblings with schizophrenia and a genetic mutation linked to major mental illnesses, Johns Hopkins researchers have created induced pluripotent stem cells (iPS cells) using a new and improved "clean" technique. Reporting online February 22 in Molecular Psychiatry, the team confirms the establishment of two new lines of iPS cells with mutations in the gene named Disrupted In Schizophrenia 1, or DISC1. They made the cells using a nonviral "epiosomal vector" that jumpstarts the reprogramming machinery of cells without modifying their original ...

Researchers at the University of Granada have proved that neuropsychological rehabilitation helps in significantly reducing cognitive, emotional and behavioural after-effects in patients with acquired brain injury, generaly due to traumatic brain injury and ictus. These patients should not wait to be treated later by the social services, since early intervention (within six months after the traumatism) reduces further after-effects. Despite the prevention campaigns launched for reducing traffic accidents and improving heart-friendly habits, traumatic brain injury and ...

A pilot study in healthy children and adolescents shows that it is feasible to screen for undiagnosed heart conditions that increase the risk of sudden cardiac arrest (SCA). Adding a 10-minute electrocardiogram (EKG or ECG) to a history and physical examination identified unsuspected cases of potentially serious heart conditions. Although more research is needed, the preliminary results suggest that a relatively low-cost screening might help identify children who are at risk for sudden cardiac arrest, possibly preventing childhood death. "In the United States, the ...

Halifax Savings research has shown that children in Wales have the highest ownership levels of games consoles and mobile phones across the nation and also spend the most amount of money on computer games and equipment. They also do extremely well when it comes to owning an iPod or MP3 player and only fall down slightly on music downloads and mobile phone expenditure. A full house for Welsh gamers 100% of the children surveyed in Wales owned a games console, well above the national average of 91%. Children in Wales also spent the highest amount of money on computer ...

Washington, D.C. (March 17, 2011) -- A team of researchers has integrated tiny detectors capable of counting individual photons on computer chips. These detectors, called "single-photon avalanche diodes (SPAD)," act like mini Geiger counters, producing a "tick" each time a photon is detected. The researchers present their findings in Applied Physics Letters, a journal published by the American Institute of Physics. "In the past, making these detectors required specialized processes, but recently there has been tremendous progress in making these devices in 'standard' ...

Researchers working in a research project within the Academy of Finland's Research Programme on Substance Use and Addictions have been developing a targeted drug that could aid in smoking reduction therapy. The new drug slows down the metabolism of nicotine, which would help smokers to cut down their smoking. Nicotine is absorbed rapidly through the lining of the mouth but most readily through the lungs, from where it quickly passes through the body and into the brain. Once the nicotine reaches the liver, it is metabolised by an enzyme called CYP2A6. Preliminary studies ...

Radioactive waste decaying down at the dump needs millions of years to stabilize. The element Neptunium, a waste product from uranium reactors, could pose an especially serious health risk should it ever seep its way into groundwater – even 5 million years after its deposition. Now, researchers at the University of Copenhagen have shown the hazardous waste can be captured and contained. The means? A particular kind of green goop that occurs naturally in oxygen-poor water. Bo C. Christiansen is a geochemist at the University of Copenhagen who specializes in "green rust". ...

With the cost savings of giving something up for Lent likely to reach GBP57.37 by Easter Sunday, Lloyds TSB Savings believes that people may consider prolonged or permanent periods of abstinence to enable them to meet long-term financial goals. Of the 66% making a lifestyle change, a third (30%) would like to sell unwanted possessions on eBay, rising to almost half (48%) of 18 to 24 year olds, but decreasing to as few as one in five (19%) in Scotland. One quarter (25%) would like to shop less, 22% to start cycling or walking to work and cutting back on going out for ...

TORONTO, Ont., March 17, 2011 — Major clinical studies that evaluate prevention strategies for heart disease and stroke fail to consider a participant's ethnicity, a factor that can more than double the rate of death in some groups, according to research led by St. Michael's Dr. Joel Ray. The study, published online in the Quarterly Journal of Medicine, reviewed 45 major clinical trials on prevention strategies. Researchers found that only 1 in 4 studies reported on the ethnicity of participants. None included information about whether a participant was an immigrant. ...

(Boston) – Researchers at Boston University School of Medicine (BUSM), in collaboration with Johns Hopkins University, have identified a potential new biomarker and therapeutic target for melanoma. The novel cell screening method used in the study also clarifies the process behind tumor metastasis and may allow the identification of biomarkers for other aggressive cancers. The findings now appear online in Cancer Research. According to the American Cancer Society melanoma is the most serious type of skin cancer and one in 55 people will be diagnosed with it during their ...

Grand Rapids, Mich. (March 17, 2011) – In a recently-published study mapping the structure and function of the so-called "orphan" nuclear receptor TR4, Van Andel Research Institute (VARI) investigators suggest that Vitamin A may play a more direct role than was previously known in certain physiological functions including sperm cell formation and the development of the central nervous system. Scientists had previously determined that Vitamin A derivatives such as retinal and the retinoic acids are involved in physiological functions in the human body. But there has ...

New Rochelle, NY, March 17, 2011—At-home, daily application of light therapy via light-emitting diodes (LEDs) placed on the forehead and scalp led to improvements in cognitive function and post-traumatic stress disorder in patients with a traumatic brain injury (TBI), according to a groundbreaking study published in Photomedicine and Laser Surgery, a peer-reviewed journal published by Mary Ann Liebert, Inc. The article is available free online at www.liebertpub.com/pho Margaret Naeser, PhD, LAc, VA Boston Healthcare System, Boston University School of Medicine, and colleagues ...
