Overweight people may benefit most
A new study led by researchers at Fred Hutchinson Cancer Research Center has found that regular yoga practice may help prevent middle-age spread in normal-weight people and may promote weight loss in those who are overweight.
The study – the first of its kind to measure the effects of yoga on weight – appears in the July/August issue of Alternative Therapies in Health and Medicine.

UF Genetics Institute researcher finds way to explore role of microRNAs in specific tissue
University of Florida researchers have learned how to selectively shut down a flyweight-sized genetic molecule that packs a heavyweight punch, a discovery that may help doctors better understand cancer, birth defects and other health problems. The finding, which will be reported this week in the online Proceedings of the National Academy of Sciences, deals with tiny strands of genetic mate
Researchers have determined that a gene present in mouse cells limits the number of times that a cell can divide. The gene is involved in a process, called senescence, which is thought to ensure that aging cells do not pass on harmful mutations.
The researchers said the gene, known as SIRT1, suppresses longevity, and may play a role in regulating the aging process. But they caution against interpreting the results too broadly, because dividing mouse cells in culture are an imper
The U.S. Environmental Protection Agency’s scientific and technical decisions in assessing risks to human health from pollution at a Superfund site in the Coeur d’Alene River Basin have been generally sound, says a new report from the National Academies’ National Research Council. And the agency’s remediation plans for residential areas should adequately protect residents against the most serious health threats, provided floods do not recontaminate cleaned-up areas. However,
Authors urge caution in JAMA article: High dose nutrient supplementation may have more adverse consequences than anticipated
In a special communication piece that appears in the July 20th issue of the Journal of the American Medical Association (JAMA), Alice Lichtenstein, DSc, senior scientist and director of the Cardiovascular Nutrition Laboratory at the Jean Mayer U.S. Department of Agriculture (USDA) Human Nutrition Research Center on Aging at Tufts University and the Center&
Camera-guided surgery through small incisions works better than conventional surgery for colon cancer and related diseases, at least in the short term recovery, a new review of previous studies confirms. In the long term, researchers found no difference between the two.
Researchers at Charité – Universitätsmedizin Berlin analyzed 25 randomized controlled trials in which the laparoscopic method – or “keyhole” surgery — was compared with the conventional method, in which a lar
Few studies compare the effects of different drug regimes in pregnant women, and many of the best studies were conducted in Southeast Asia, where malaria transmission rates are low, says researcher Lois Orton of the University of York in England. “Reliable research about the benefits and harms of treatments for malaria in pregnant women is scarce,” Orton says.
The review appears in the July issue of The Cochrane Library, a publication of The Cochrane Collaboration, an international o
Cigarette smoking continues to be the principal cause of premature death in the nation and a major cause of medical expenditures and lost productivity. Of the 46.5 million adults in the United States who smoke, about 70% will see a primary care provider at least once a year. The United States Public Health Service (USPHS), in an effort to reduce cigarette smoking, recommends a 5-step process that includes: (1) Asking every patient about tobacco use, (2) Advising all smokers to quit, (3) Assessin
Insulin, a hormone long recognized as a generator of fat, also keeps fat in the liver under control, according to a new study in the July issue of Cell Metabolism. The newly discovered role for insulin may explain how an organ frequently flooded with the fat-building hormone normally stays trim and also suggests new dietary strategies and treatments to avoid fatty liver, a growing healthcare epidemic, said the researchers.
Insulin produced by the pancreas allows cells to take up glucose
Patient reminders can help physicians improve immunization rates for their practice, according to a new review of studies.
All six of the reminder and recall systems tested — including post cards, letters and phone calls — resulted in better immunization coverage, the review finds. The boost in immunization rates held true for both adults and children — and across an array of clinical settings. The review, which encompasses 43 patient-reminder studies, found immunization increases
Four Kingston University engineering students are getting a taste of life in space taking part in a European Space Agency (ESA) flight that recreates the weightlessness felt by astronauts once they leave the Earth’s atmosphere. The four have been finding out what it is like to float in zero gravity aboard a special ESA aircraft in Bordeaux, France while carrying out experiments on a lightweight solar kite being developed by Kingston researchers.
The team is one of 30 from across Europe
Almadraba is a fishing art whereby a labyrinth of nets intercept the migratory movements of the large tuna, when they cross the Gibraltar Straits. This study, undertaken by AZTI-Tecnalia, involved analysing the chain of marketing of the tuna fish, from the catch in the almadrabas to its freezing – the aim being to design a monitoring system adapted to this mode of fishing -, to its handling and processing and to the first stages of marketing the product. The end target is the design of an identifyi
An international consortium of 7 universities and research centres are seeking an alternative to silicon-based microelectronics in using molecules of DNA, which could enable a reduction in size of the current systems by a thousand times. The University of the Basque Country (UPV/EHU) is participating in this project through the research group led by Professor Ángel Rubio Secades of the Department of Materials Physics.
The really innovative nature of this project lies, on the one hand, in th
Believers in Brazil can choose from a wide variety of religions. The main reason for this rich selection lies in the country’s colonial history and its current socio-economic development. This is the key message of a project recently concluded by the Austrian Science Fund FWF in order to analyze why Brazil of all countries experiences such a big run on faith.
Millions of Europeans were under the spell of the elections for the new Pope, but the truth is that religions are losing
Scientists at the University of Bath will be taking part in an international £4.2 million ($7.5 million) research project that could help millions of people avoid starvation.
The BioCassava Plus project will improve the nutritional and storage properties of cassava (Manihot esculenta), the primary food source for more than 250 million Africans and a substantial portion of the diet of nearly 600 million people worldwide.

Results of a genetic linkage analysis of PRKCB1 with autism published
Scientists working at IntegraGen SA, the personalized medicines company, have shown that variations in the gene for protein kinase C beta 1 (PRKCB1), a protein with an important role in brain function, are strongly associated with autism. This exciting finding suggests some answers to a number of previous, but unexplained, observations about autism and provides the potential for a mechanistic explanation for som
