Large-scale analysis identifies 32 genetic loci for obesity
An international team of researchers has identified 18 new genetic loci associated with obesity assessed by BMI, and confirmed a link between obesity and 14 previously known loci. Almost 250,000 individuals were included in the analysis, which is published. "We know that hereditary factors play a key role in the development of obesity, and thus in increasing risk of many diseases such as cardiovascular disease and diabetes," says Erik Ingelsson, professor at the Department of Medical Epidemiology and Biostatistics at Karolinska Institutet, and one of the principal investigators of the study.

Research examines cycle of overeating and obesity
AUSTIN, Texas — New research funded through The University of Texas at Austin provides evidence of the vicious cycle created when an obese individual overeats to compensate for reduced pleasure from food. Obese individuals have fewer pleasure receptors and overeat to compensate, according to a study by University of Texas at Austin senior research fellow Eric Stice and his colleagues published this week in The Journal of Neuroscience .

New research: infant nutrition and obesity
New research: infant nutrition and obesity
Researchers at the UCL Institute of Child Health have demonstrated for the first time in humans that feeding babies enriched milk led to statistically significant increases in body fat at age 5-8 years. The new study is published today online in the American Journal of Clinical Nutrition . This key finding of the link between overnutrition in infancy and body fat was independent of confounding factors such as maternal Body Mass Index.

Obesity increases risk of periodontal disease in teens
[NEWS, 28 September 2010] Teens with obesity are at increased risk of developing periodontal disease as a result of inflammation of the gums. This according to a study from Karolinska Institutet, recently published in International Journal of Pediatric Obesity. In the study, a group of teenagers with obesity were compared with the same number of teenagers with normal weight.

NASA Study Shows Desert Dust Cuts Colorado River Flow
NASA Study Shows Desert Dust Cuts Colorado River Flow
PASADENA, Calif. Snowmelt in the Colorado River basin is occurring earlier, reducing runoff and the amount of crucial water available downstream. A new study shows this is due to increased dust caused by human activities in the region during the past 150 years. The study, led by a NASA scientist and funded by the agency and the National Science Foundation, showed peak spring runoff now comes three weeks earlier than before the region was settled and soils were disturbed.

WASHINGTON - Snow melt in the Colorado River basin is occurring earlier, reducing runoff and the amount of crucial water available downstream. A new study shows this is due to increased dust caused by human activities in the region during the past 150 years. The study, led by a NASA scientist and funded by the agency and the National Science Foundation (NSF), showed peak spring runoff now comes three weeks earlier than before the region was settled and soils were disturbed.

Expanded Irrigation Masks Global Warming Effects While Sowing the Seeds for Famine
Expanded irrigation has made it possible to feed the world's growing billions—and it may also temporarily be counteracting the effects of climate change in some regions, say scientists in a new study. But some major groundwater aquifers, a source of irrigation water, are projected to dry up in coming decades from continuing overuse, and when they do, people may face the double whammy of food shortages and higher temperatures.

UW-Madison researchers release Wisconsin Poverty Report: New measure tells new story
The second Wisconsin Poverty Report shows the rate of poverty in Wisconsin worsened in 2008, with more than 11 percent of the state's population living in need, including one in seven children and one in 10 elderly residents. Produced by the Institute for Research on Poverty (IRP) at the University of Wisconsin-Madison, the report issued today (Sept.

Some vitamin supplements increase presence of the HIV virus in breast milk
ANN ARBOR, Mich.—Vitamin A and beta-carotene supplements are unsafe for HIV-positive women who breastfeed because they may boost the excretion of HIV in breast milk—thereby increasing the chances of transmitting the infection to the child, a pair of new studies suggest. Epidemiologist Eduardo Villamor of the University of Michigan School of Public Health says transmission of HIV through breastfeeding happens because breast milk carries viral particles that the baby ingests.

Polyphenol antioxidents inhibit iron absorbtion
University Park, Pa. — Health benefits from polyphenol antioxidants — substances found in many fruits and vegetables — may come at a cost to some people. Penn State nutritional scientists found that eating certain polyphenols decreased the amount of iron the body absorbs, which can increase the risk of developing an iron deficiency.

Excess maternal weight gain increases birth weight, study finds
Excess maternal weight gain increases birth weight, study finds
Expectant mothers who gain large amounts of weight tend to give birth to heavier infants who are at higher risk for obesity later in life. But it's never been proven that this tendency results from the weight gain itself, rather than genetic or other factors that mother and baby share. A large population-based study from Harvard researchers at Children's Hospital Boston , looking at two or more pregnancies in the same mother, now provides evidence that excess maternal weight gain is a strong, independent predictor of high birth weight.

Kids could get more whole grains from after-school snacks, University of Minnesota study finds
MINNEAPOLIS / ST. PAUL (07/22/2010) —An after-school snack of graham crackers might be one way to get children to eat more whole grains, a new study from the University of Minnesota shows. Federal nutrition guidelines recommend at least three servings a day of whole-grain foods, but previous studies have found that children typically only eat about one serving per day, largely because they don't like the taste or texture of whole-grain foods.

Hunger atlas takes a new look at an old problem
Hunger atlas takes a new look at an old problem
CHAMPAIGN, Ill. World hunger is often seen as the result of overpopulation, bad geography or natural or human-made disasters. But a new book, 'The Atlas of World Hunger,' reveals that the contours and causes of hunger are more complex - and in some ways more easily addressed - than those old assumptions suggest.

Scientists find natural way to curb your greed
University of Manchester scientists have discovered a naturally-occurring appetite suppressant that could be used to make a diet drug without side effects. Professor Simon Luckman and Dr Garron Dodd believe the peptide hemopressin, which affects the reward part of the brain responsible for hedonistic behaviour, might treat some aspects of alcohol and drug abuse.

Obesity epidemic may be flattening out - but no time for complacency say experts
The prevalence of childhood obesity might be stabilising in developed countries, but there is still much to be done to combat this major threat to health, according to a Seminar published on Online First and in an upcoming issue of The Lancet. In 2010, more than 40 per cent of children in the North American and eastern Mediterranean World Health Organisation (WHO) regions, 38 per cent in Europe, 27 per cent in the western Pacific and 22 per cent in southeast Asia are predicted to be overweight or obese.

Climate study backs plants
Results from the study contrast with previous scientific research that had suggested that plants were responsible for producing large amounts of the greenhouse gas. To reach their conclusions, scientists created artificial leaves made from plant pectin and measured the methane produced when the leaves were exposed to sunlight.
