Boston, MA – A new study from the Harvard School of Public Health (HSPH) finds that high body mass index (BMI) in developing countries remains primarily a problem of the rich. The findings suggest that the shift towards overweight and obesity among the poor that has already happened in wealthier countries has not yet happened in developing countries. The study appears in an advance online edition of the American Journal of Clinical Nutrition and will appear in an upcoming print edition. "Previous research on the increasing overweight and obesity burden in developing countries ...

ROCHESTER, Minn. -- A new Mayo Clinic study (http://newsblog.mayoclinic.org/2008/12/03/brain-tumors-best-treatments-for-long-term-survival/) found that children with low-grade brain tumors (gliomas) (http://www.mayoclinic.org/brain-tumors/) who undergo aggressive surgery to completely remove the tumor have an increased chance of overall survival. If complete removal is not possible, adding radiation therapy to a less complete surgery provides patients with the same outcomes as a complete removal. This study was presented at the Society for NeuroOncology Annual Scientific ...

WASHINGTON, Nov. 22, 2010 — The science that helped make today's smartphones and iPods smaller but more powerful than yesterday's desktop computers highlights the latest episode in the American Chemical Society (ACS) Prized Science video series. The new high-definition video, released today, focuses on IBM chemist Robert Miller, winner of the 2010 ACS Award for Chemistry of Materials.

New findings by civil engineering researchers in the University of Minnesota's College of Science and Engineering shows that treating municipal wastewater solids at higher temperatures may be an effective tool in the fight against antibiotic-resistant bacteria. Heating the solid waste to 130 degrees Fahrenheit (55 degrees Celsius) was particularly effective in eliminating the genes that confer antibiotic resistance. These genes are used by bacteria to become resistant to multiple antibiotics, which are then known as "superbacteria" or "superbugs." The research paper ...

More and more people have become aware of the dangers of excessive fructose in diet.

It was funded by a $3.5 million grant from the National Institute on Aging. UCR researchers G. John Andersen, professor of psychology; Rui Ni, formerly a postdoctoral ...

The same powerful drugs that have extended the lives of countless people with HIV come with a price – insulin resistance that can lead to diabetes and cardiovascular disease. Now, researchers at Washington University School of Medicine in St. Louis have determined why that happens. Their research shows that HIV protease inhibitors directly interfere with the way blood sugar levels are controlled in the body. This leads to insulin resistance, a condition that occurs when the body produces enough insulin but doesn't use it properly. This confirmation provides the potential ...

WEST LAFAYETTE, Ind. - Purdue University scientists have found the last undiscovered gene responsible for the production of the amino acid phenylalanine, a discovery that could lead to processes to control the amino acid to boost plants' nutritional values and produce better biofuel feedstocks. Natalia Dudareva, a distinguished professor of horticulture, and Hiroshi Maeda, a postdoctoral researcher in Dudareva's laboratory, determined that the gene is one of 10 responsible for phenylalanine production in plants. Understanding how the amino acid is produced could provide ...

Biologists have long thought that interactions between plants and pollinating insects hasten evolutionary changes and promote biological diversity. However, new findings show that some interactions between plants and pollinators are less likely to increase diversity than previously thought, and in some instances, reduce it. Findings, published in the Journal of Evolutionary Biology, show that local populations of one of the most distinctive plants in the Mojave Desert, the Joshua tree, are not as biologically diverse as would be expected. Joshua trees cannot produce seeds ...

Upper-class people have more educational opportunities, greater financial security, and better job prospects than people from lower social classes, but that doesn't mean they're more skilled at everything. A new study published in Psychological Science, a journal of the Association for Psychological Science, finds surprisingly, that lower-class people are better at reading the emotions of others. The researchers were inspired by observing that, for lower-class people, success depends more on how much they can rely on other individuals. For example, if you can't afford ...

Current state-of-the-art global climate models predict substantial warming in response to increases in greenhouse gases such as carbon dioxide. The models, though, disagree widely in the magnitude of the warming we can expect. The disagreement among models is mainly due to the different representation of clouds. Some models predict that global mean cloud cover will increase in a warmer climate and the increased reflection of solar radiation will limit the predicted global warming. Other models predict reduced cloudiness and magnified warming. In a paper that has just appeared ...

Astronomers find cosmic dust annoying when it blocks their view of the heavens, but without it the universe would be devoid of stars. Cosmic dust is the indispensable ingredient for making stars and for understanding how primordial diffuse gas clouds assemble themselves into full-blown galaxies. "Formation of galaxies is one of the biggest remaining questions in astrophysics," said Andrey Kravtsov, associate professor in astronomy & astrophysics at the University of Chicago. Astrophysicists are moving closer to answering that question, thanks to a combination of new ...
