California's coastal fog has decreased significantly over the past 100 years, potentially endangering coast redwood trees dependent on cool, humid summers, according to a new study by University of California, Berkeley, scientists.
It is unclear whether this is part of a natural cycle of the result of human activity, but the change could affect not only the redwoods, but the entire redwood ecosystem, the scientists say.
Westchester, Ill. –A study in the Feb. 15 issue of the Journal of Clinical Sleep Medicine shows that sleepiness at the wheel and poor sleep quality significantly increase the risk of motor vehicle accidents in adolescents.
ST. PAUL, Minn. – Watching TV medical shows might not be the best way to learn what to do when someone has a seizure. Researchers screened the most popular medical dramas and found that doctors and nurses on the shows responded inappropriately to seizures almost half the time, according to a study released today that will be presented at the American Academy of Neurology's 62nd Annual Meeting in Toronto April 10 to April 17, 2010.
CAMBRIDGE, Mass., By creating diamond-based nanowire devices, a team at Harvard has taken another step towards making applications based on quantum science and technology possible.
The new device offers a bright, stable source of single photons at room temperature, an essential element in making fast and secure computing with light practical.
The finding could lead to a new class of nanostructured diamond devices suitable for quantum communication and computing, as well as advance areas ranging from biological and chemical sensing to scientific imaging.
While many of us enjoyed constructing little houses out of toy bricks when we were kids, this task is much more difficult if bricks are elementary particles. It is even harder if these are particles of light – photons, which can only exist while flying at an incredible speed and vanish if they touch anything.
Thinking about a typical victim of college dating violence, you're probably imagining her, not him, and exaggerations and self-reporting surveys spun as fact only make the gap seem wider, but that is not the case, according to a Kansas State University expert on intimate partner violence. Sandra Stith, a professor of family studies and human services, said most research has looked at men as offenders and women as victims.
COLUMBIA, Mo. –President Obama's "Race to the Top" grant program, which encourages school districts to compete for $4.35 billion, has made a strong push for education reform. While much of the education reform debate has focused on issues of adequate funding and teacher qualifications, few have addressed the role of citizen involvement in local education policy making. A University of Missouri researcher has examined the link between school board elections and local school performance.
Politicians from all parties must renew their commitment to tackling health inequalities if we are to create a fairer society, say researchers on bmj.com today.
Their views come as an independent review by Professor Sir Michael Marmot is published, outlining the most effective strategies for reducing health inequalities in England from 2010.
ST. PAUL, Minn. –Workers and residents exposed to dust and fumes caused by the collapse of the World Trade Center on September 11, 2001 frequently reported headache years later, according to research released today that will be presented at the American Academy of Neurology's 62nd Annual Meeting in Toronto April 10 to April 17, 2010.
Twenty years after the Civil War ended, the 179,000 African-American veterans of the Union Army saw racial inequality widen as the Pension Bureau left most of them out of a rapid expansion.
According to a new Brigham Young University study, the program shifted away from its relatively color-blind roots when it began granting disability claims based on chronic illness to soldiers who had not been wounded in the war.
When it comes to meeting national health goals for physical activity, Mexican-Americans are the most active group in America and may benefit from exercise that researchers typically have not measured, according to research by scholars at the University of Chicago and Arizona State University.
The new research, which used electronic devices to measure people's movement, challenges other studies based on self-reports that claimed non-Hispanic whites are most likely to be physically active.
Badger culling is unlikely to be a cost-effective way of helping control cattle TB in Britain, according to research published today in PLoS ONE. The authors of the study, from Imperial College London and the Zoological Society of London, say their findings suggest that the benefits of repeated widespread badger culling, in terms of reducing the incidence of cattle TB, disappear within four years after the culling has ended.
The first of a series of reports, the ACSS has collected a number of stories which demonstrates how evidence-based research can be translated into policies that will improve everyone's wellbeing. The impact of social science research is wide reaching – from crime prevention, education and re-employment to healthy diets and the wellbeing of children.
Globalisation, and particularly cheaper electronic goods from China and the Far East, has altered behaviour among Britain's burglars according research in progress at the University of Leicester.
James Treadwell, a lecturer in Criminology from the University of Leicester's Department of Criminology suggests that the incredible rise of the new superpower has made burglars 'redundant' due to the decline in cost of household goods traditionally targeted by thieves.
Treadwell is currently researching how crime has changed over time. He commented:
Research performed at the University of Granada (Spain) say it has proved that role-playing games (RPGs) have a very positive effect on the knowledge and habits of physical and sports practice from a health viewpoint in students of Secondary Education and that role playing can make exercise and healthy life habits more attractive for teenagers.
To conduct the study, the authors prepared an intervention program based on a role-playing game at the Institute of Secondary Education of Granada. The study was carried out over 3 months with 1-hour sessions twice per week.
