Why piglets shudder to keep warm
Piglets are sensitive to cold and shiver to maintain their body heat. Researchers at Uppsala University have uncovered a genetic reason why these newborns are less tolerant of the cold than other newborn mammals. view more (2006-08-21)
Weight control protein may yield antiobesity drugs
A weight control protein with a key role in the brain's ability to monitor body fat content may yield new approaches for treating obesity and type 2 diabetes, according to a new report in the August issue of Cell Metabolism. view more (2005-08-17)
Signaling for cartilage
Skeletal progenitor cells differentiate into cartilage cells when one master gene actually suppresses the action of another, said Baylor College of Medicine researchers in a report that appears online in the journal Proceedings of the National Academy of Sciences. view more (2006-11-28)
Location, location — Cell sizes, lives influenced by host size
Cells from the smallest to the largest of mammals often seem to be "one size fits all." Now a closer look reveals that whether a cell lives in an elephant, mouse or something in between can make a big difference in its life. view more (2007-03-09)
Fatty acid catabolism higher due to polyphenol intake
Polyphenols, dietary substances from vegetables, fruits and green tea, bring about a change in the energy metabolism. Dutch researcher Vincent de Boer has discovered that polyphenols increase the fatty acid breakdown in rats and influence the glucose use in fat cells. view more (2007-05-15)
Pittsburgh researchers identify source of multipotent stem cells with broad regenerative potential
In a promising finding for the field of regenerative medicine, stem cell researchers at Children's Hospital of Pittsburgh of UPMC have identified a source of adult stem cells found on the walls of blood vessels with the unlimited potential to differentiate into human tissues such as bone, cartilage and muscle. view more (2008-09-22)
BMI criteria for obesity surgery should be lowered, UT Southwestern researcher suggests
UT Southwestern Medical Center researchers have found that the existing body mass index criteria for obesity surgery often excludes a group of obese patients at risk of cardiovascular disease. view more (2007-12-18)
Visceral fat build-up is the high cost of inactivity
Inactivity leads to significant increases in visceral fat, and a moderate exercise regimen can keep this potentially dangerous form of fat at bay, according to the results of the first randomized clinical trial evaluating the effects of exercise amount and intensity in sedentary overweight men and women. view more (2005-09-14)
Microwaves offer fat chance to probe supermarket food
Microwaves used for zapping instant meals can also be used to determine the fat and salt content of supermarket food, according to research carried out at two Manchester universities. view more (2007-09-20)
Eating and weight gain not necessarily linked, study shows
A new study shows that increased eating does not necessarily lead to increased fat. The finding in the much-studied roundworm opens the possibility of identifying new targets for drugs to control weight, the researchers say. view more (2008-06-04)
UCSF discovers new glucose-regulating protein linked with diabetes
Researchers at the University of California, San Francisco, and collaborators at Harvard Medical School have linked a specialized protein in human muscles to the process that clears glucose out of the bloodstream, shedding light on what goes wrong in type 2 diabetes on a cellular level. view more (2009-05-29)
Study shows direct link between leptin and obesity-related cardiovascular disease
Obese people who don't have high cholesterol or diabetes might think they're healthy - despite the extra pounds. view more (2008-11-11)
Impact of exercise on body fat is different for boys and girls
The impact of exercise on body fat differs for boys and girls, suggests research published ahead of print in the British Journal of Sports Medicine. view more (2007-03-29)
Sugars in liver found to clear fats from the bloodstream
Maybe you ate a big, juicy steak for dinner last night, adding a large amount of fat - scientifically known as triglycerides - to your system. For one in ten of us, that could be a big problem. view more (2007-01-03)
Protein made by fat cells may increase risk of heart attack in older adults
Adiponectin, a protein produced by fat cells, may play a pivotal and counterintuitive role in cardiovascular health for older Americans according to a new study accepted for publication in the Journal of Clinical Endocrinology & Metabolism (JCEM). view more (2008-07-30)
Calorie density key to losing weight
Eating smart, not eating less, may be the key to losing weight. A year-long clinical trial by Penn State researchers shows that diets focusing on foods that are low in calorie density can promote healthy weight loss while helping people to control hunger. view more (2007-06-08)
Researchers at UH Explore use of Fat Cells as Heart Attack Therapy
For those of us trained to read nutrition labels, conventional wisdom tells us that fat isn't good for the heart. But a team of University of Houston researchers has set out to use fat cells to beef up heart muscles damaged by heart attack - and they're using an out-of-this-world device to do it. view more (2008-10-28)
Study finds fitness level, not body fat, may be stronger predictor of longevity for older adults
Adults over age 60 who had higher levels of cardiorespiratory fitness lived longer than unfit adults, independent of their levels of body fat, according to a study in the December 5 issue of JAMA. view more (2007-12-05)
Community-intervention study links successful town makeover focused on boosting calcium and exercise
The battle against obesity in this country could be tackled one community at a time, according to a newly published study in the Journal of Physical Activity and Health. Researchers at the University of Colorado at Denver demonstrated the effectiveness of changing behaviors at a community level, suggesting that community-based interventions could... view more...

Researchers engineer metabolic pathway in mice to prevent diet-induced obesity
In recent years, obesity has taken on epidemic proportions in developed nations, contributing significantly to major medical problems, early death and rising health care costs. view more (2009-06-03)
