Europe is facing a “major health and social burden” as the obesity epidemic reaches crisis point, experts warned today. Governments, whose health ministers have already signed the ‘European Charter’ pledging to halt the rise in obesity by 2015, must now back more intensive research programmes, and gear up to cope with the scale of the epidemic, which is damaging quality of life and reducing life expectancy. The challenge came as the latest developments in obesity research were unveiled by leading international scientists attending the 15th European Congress on Obesity taking place in…

The April 23, 2007 Chemistry and Engineering News article on the Social Software in Education symposium at the American Chemical Society spring meeting in Chicago has come out. I gave a talk there on using blogs and wikis to teach organic chemistry. The article is a pretty comprehensive report on the session and does a good job of summarizing the key technologies currently being tried without much hype. Podcasting, vodcasting, tagging and wikis were discussed from teachers and librarians using them in different ways. Of course the controversial issue of attendance was highlighted. Although…

Early menarche tends to be preceded by rapid infancy weight gain and is associated with increased childhood and adult obesity risk. As age at menarche is a heritable trait, we hypothesised that age at menarche in the mother may in turn predict her children's early growth and obesity risk. Methods and Findings We tested associations between mother's age at menarche, mother's adult body size and obesity risk, and her children's growth and obesity risk in 6,009 children from the UK population-based Avon Longitudinal Study of Parents and Children (ALSPAC) birth cohort who had growth and fat…

Research led by Dartmouth scientists found that animals fed nutritious, high-quality food end up with much lower concentrations of toxic methylmercury in their tissues. The result suggests ways in which methylmercury—a neurotoxin that can accumulate to hazardous levels—can be slowed in its passage up the food chain to fish. "This research provides evidence that by eating high-quality food, organisms may reduce their bodily concentration of a contaminant," said lead author Roxanne Karimi, a graduate student in the Dartmouth Department of Biological Sciences. "These findings allow us to…

A wide variety of public policies affect alcohol purchases, consumption, and traffic fatalities, The two alcohol-control policies that have been most-clearly demonstrated to reduce youth consumption and traffic deaths are raising the minimum legal drinking age (MLDA) and raising beer taxes. Researchers have evaluated the independent effectiveness of these and many other policies. A new study finds that the effectiveness of any particular policy depends on what other policies are also in place. "Most prior studies indicate that governments can significantly reduce youth traffic fatalities by…

Just as an editorial note, we try to stay as politically agnostic as possible. No site can be objective but we at least try to be balanced - left, right, we don't much care. We just want it to be science. This is a news release and it's from a group that, we are told, has a left wing agenda. News releases aren't endorsements of the content and we often change the titles to look less inflammatory, just as we did here. It's a science study so anyone who writes to write more on the GNEP program can contribute as well. Congress is now considering whether to approve or zero out the $405…

Controlling the properties and behavior of matter at the smallest scale—in effect, "domesticating atoms"—can help to overcome some of the world’s biggest challenges, concludes a new report on how diverse experts view the future of nanotechnology. Released today, NanoFrontiers: Visions for the Future of Nanotechnology, summarizes discussions among over 50 scientists, engineers, ethicists, policymakers, and other experts, as well as information gathered in follow-up interviews and from specially prepared background papers, about the long-term potential of nanotechnology. Written by freelance…

EU legislation to promote the uptake of biodiesel will not make any difference to global warming, and could potentially result in greater emissions of greenhouse gases than from conventional petroleum derived diesel. This is the conclusion of a new study reported today in Chemistry & Industry. Analysts at SRI Consulting compared the emissions of greenhouse gases by the two fuels across their overall life cycles from production to combustion in cars. The results show that biodiesel derived from rapeseed grown on dedicated farmland emits nearly the same amount of greenhouse gas emissions…

Medical professionals conducting clinical trials should provide more information about financial conflicts of interest before they talk to patients about participating in the trials. That is one of the main conclusions of a new survey by researchers from Duke University Medical Center and Johns Hopkins University. Their study found that 41 percent of the clinical trial coordinators surveyed had experience disclosing financial aspects of the trial to potential participants, and 28 percent of the coordinators had been asked by participants about potential financial conflicts. Financial…

I often find that books on the history of science and technology are fun to read because they give me an opportunity to try to forget what I know about how things turned out and piece together an older worldview. For example, I am currently reading the new book by Tom McNichol "AC/DC - The Savage Tale of the First Standards War". On p. 38 is reprinted part of Edison's article in North American Review, written in 1878, shortly after his invention of the phonograph: Among the many uses to which the phonograph will be applied are the following: ... 2. Phonographic books, which will speak to…
