Researchers from Duke University Medical Center and the Medical College of Wisconsin have shown that removing a portion, instead of all, of the spleen, can successfully treat children with a variety of congenital anemias while preserving important splenic immune function.
In the largest study of its kind in the U.S., the researchers performed the surgery, known as a partial splenectomy, on 25 children with congenital forms of anemia caused by abnormal red blood cells. Typically, these
Expert in ‘emotional communication’ says 1-year-olds can pick up ‘emotional signals’ and base decisions on them
What do infants learn as they watch people talk or act in a certain manner? If a television is on in a room, how much do infants pay attention to it?
These are questions Donna Mumme, assistant professor of psychology at Tufts University, answers in her study, “The Infant as Onlooker: Learning from Emotional Reactions Observed in a Television Scenario.” Co-authored
A golden early old age is within sight for many people, says new research funded by the Economic and Social Research Council, which demonstrates that the good life is much less influenced by your past – the job your father had, for instance – than by the present, when two of the most important influences are having choices about working or not working, and having friends in whom you can confide.
“Good quality of life in early old age is a realistic ambition for all”, says the research team,
Nicotine administration in humans is known to sharpen attention and to slightly enhance memory. Now scientists, using functional magnetic resonance imaging (MRI), have identified those areas of the brain where nicotine exerts its effects on cognitive skills.
Their findings suggest that nicotine improves attention in smokers by enhancing activation in the posterior cortical and subcortical regions of the brain–areas traditionally associated with visual attention, arousal, and motor a
In recent years a new view of health has emerged. The change has been so momentous that it has been called a paradigm shift. But what kind of social transformation are we experiencing? What is actually meant by ‘health promotion’? This is what Peter Korp at the University of Trollhättan/Uddevalla has investigated in his doctoral dissertation in sociology. The study is the first to be carried out on the basis of conditions in Sweden.
The view of how health is dealt with in society ha
Nearly four decades of research conclude that power toothbrushes with rotation oscillation action, such as the Oral-B 3D Excel, are demonstrably more effective in removing plaque and reducing gingivitis than other types of power toothbrushes — including those featuring “sonic” technology — according to an international study announced today at the Forsyth Institute conference on evidence-based dentistry.
Half of adults age 18 or older have some evidence of gingivitis, the earliest
Whether you fancy yourself a jet-setting sophisticate or a down-to-earth outdoorsy type, a fast-track corporate star or an all-around nice guy, new research indicates that you probably tune out information that challenges your self-image by tuning in to television.
The findings, by Sophia Moskalenko of the University of Pennsylvania and Steven Heine of the University of British Columbia, are presented in a paper published in the January issue of the Personality and Social Psychology Bulletin.
Nearly 20 percent of smokers using an over-the-counter nicotine patch in a new study were able to quit smoking entirely after six weeks, compared to only 7 percent of smokers using a dummy patch. Each group reported only mild side effects from patch use, like rashes or insomnia.
None of the smokers received any direct instruction on how to use the patch or got behavioral counseling to help them quit smoking, which suggests that nicotine patches used in an over-the-counter manner can be safe
Baby’s first look at the world is likely a dizzying array of shapes and motion that are meaningless to a newborn, but researchers at the University of Rochester have now shown that babies use relationships between objects to build an understanding of the world. By noting how often objects appear together, infants can efficiently take in more knowledge than if they were to simply see the same shapes individually, says the paper published in the current issue of Proceedings of the National Academy
“In Denmark, 67 per cent of mothers of children under 16 are in full-time employment; in the Netherlands the proportion is only 11 per cent.”
New ESRC research highlights the diversity of employment patterns in the European Union. The study, specially commissioned to be presented at the ESRC’s sixth national social science conference was prepared by Richard Berthoud and Maria Iacovou, of the Essex University’s Institute for Social and Economic Research (ISER). It is largely
The reputation of an organization can convince scientists of the value of the research it produces even when there is no supporting data, says a University of Toronto geologist.
Professors Andrew Miall of U of T’s geology department and Charlene Miall of sociology at McMaster University have found that reputation alone can significantly influence the legitimacy placed on scientific results produced by an organization. The researchers have named this phenomenon the Exxon factor – in the
Microchips may be small, but their impact on our world has been huge. And this impact goes beyond the obvious effects of e-mail, cell phones and electronic organizers: A new study shows that the “environmental weight” of microchips far exceeds their small size.
Scientists have estimated that producing a single two-gram chip — the tiny wafer used for memory in personal computers — requires at least 3.7 pounds of fossil fuel and chemical inputs. The findings were reported Oct. 25 on the Web si
Computer prescriptions are three times less likely to contain errors than handwritten prescriptions
Have you ever received a drug prescription from a physician that looked like chicken scratch? You’re not alone. Pharmacists sometimes have a hard time reading prescriptions and in some cases they also are incomplete. To avoid errors, pharmacists have to spend precious time tracking down prescribers to clarify illegible or possibly inaccurate prescriptions. A new study by researcher
Soy protein enriched with isoflavones appears to have no effect on bone mineral content and bone mineral density in young women, according to a new study. Researchers say the finding will disappoint nutritionists hoping to document benefits from diets containing the nutrients, not to mention the soy industry.
A report on the study, conducted at the University of North Carolina at Chapel Hill, appears in the current (October) issue of the Journal of the American College of Nutrition. Isofla
Broad community initiatives that use local coalitions to reduce alcohol and drug abuse are largely ineffective and may even have a negative effect for some goals, according to a new study of Robert Wood Johnson Foundation’s Fighting Back campaign.
“Supporting the activities of local coalitions is both intuitively attractive (bringing the community together to address local problems) and politically popular (spreading the money around),” says Denise Hallfors, Ph.D., of the Pacific Instit
People who live, work or travel within 165 feet downwind of a major freeway or busy intersection are exposed to potentially hazardous particle concentrations up to 30 times greater than normal background concentrations found at a greater distance, according to two recently published UCLA studies.
The studies — published in the Journal of the Air and Waste Management Association and in Atmospheric Environment — show that proximity to a major freeway or highway dramatically increases exposu
