Archaeologists who interpret Stone Age culture from discoveries of ancient tools and artifacts may need to reanalyze some of their conclusions.
That's the finding suggested by a new study that for the first time looked at the impact of water buffalo and goats trampling artifacts into mud.
Researchers from Utrecht University who studied the effect of negative emotions on pain perception in women with and without fibromyalgia found that anger and sadness amplified pain equally in both groups. Full findings are now online and will publish in the October print issue of Arthritis Care & Research, a journal of the American College of Rheumatology.
Over the past decade, psychotropic medication use in the general youth population has more than doubled. Estimated rates of psychotropic medication use in foster care youth, however, are much higher (ranging from 13-52%) than those in the general youth population (4%).
Adjustments, applications and other tools allow users to configure preferences and use services such as iGoogle and Yahoo to control and customize the news they consume online. These tools can make online experiences more efficient and productive, but they do not ensure that users will be consistently pleased with their selections, according to Penn State researchers.
People who leave strict religious groups are more likely to say their health is worse than members who remain in the group, according to a Penn State researcher.
The percentage of people who left a strict religious group and reported they were in excellent health was about half that of people who stayed in the group, said Christopher Scheitle, senior research assistant in sociology.
FORT COLLINS – The hiatus of global warming in the Northern Hemisphere during the mid-20th century may have been due to an abrupt cooling event centered over the North Atlantic around 1970, rather than the cooling effects of tropospheric pollution, according to a new paper appearing today in Nature.
September 22, 2010 -- Most studies of the food choices available near public schools have focused on fast food outlets rather than the full range of options available to schoolchildren. A new study by researchers at Columbia University's Mailman School of Public Health examined the patterns of exposure to a broad range of food outlets for school children in New York City.
Children conceived by in vitro fertilization (IVF) perform the same as their peers on academic tests at all ages from grade 3 to 12, according to a new University of Iowa study.
The study in the journal Human Reproduction found that children who were conceived by IVF actually scored better than age- and gender-matched peers on the Iowa Test of Basic Skills and the Iowa Test for Educational Development (ITBS/ED), which seems a little silly of them to highlight - unless they are contending IVF makes kids smarter.
EAST LANSING, Mich. — Developing language skills appears to be more important for boys than girls in helping them to develop self-control and, ultimately, succeed in school, according to a study led by a Michigan State University researcher.
Just about everyone has a story about being trapped in the wrong job, flip-flopping careers in search of one that fits, or just wasting time with the guidance counsellor.
Imagine the impact of a new system that would easily and accurately identify individual strengths, point people toward occupations in demand, estimate the likelihood that they would be good at them and help determine whether they would enjoy them. It would be the human resources equivalent of speed-dating, but with a higher chance of going home happy.
Community Health Workers can safely and effectively provide integrated management of pneumonia and malaria to communities by dispensing amoxicillin to children with non-severe pneumonia and artemether-lumefantrine to children with malaria (after using rapid diagnostic tests). Furthermore, these activities result in a significant increase in the proportion of appropriately-timed antibiotic treatment for non-severe pneumonia and in a significant decrease in inappropriate use of antimalarials.
Thirty years ago, and a quarter of a century after randomized trials had become widely accepted, Archie Cochrane reproached the medical profession for not having critical summaries of all randomized controlled trials. At that time, there were about 14 reports of trials published per day.
There are now 75 clinical trials and 11 systematic reviews of trials published every day, with no signs of slowing. How will researchers cope with the volume and the continued poor quality of many of these studies, ask a group in PLoS Medicine.
