Finding a substance that increases beta cells, says Karsenty, "is a holy grail for diabetes research. If what's true for mice proves true for humans, "then we have inside us a hormone that does precisely this." In mice that are programmed to overeat and mice that are fed fatty diets, high levels of osteocalcin prevented both obesity and diabetes. Karsenty is now examining whether giving diabetic mice osteocalcin will reverse the disease...
...David Pierce, researchers at the University of Alberta studied the eating habits of young rats, and found that they tended to overeat when they were fed "diet" foods. Though the new study was conducted in animals, it adds to a growing body of research in humans that suggests a diet-foods paradox: the more low-calorie (or even zero-calorie) sodas and foods you consume, the more your body demands payback for the calories it was deprived...
...calorie foods that are packed with fat and carbohydrates, the crucial biological fuel that rapidly growing juveniles need. Using classic Pavlovian conditioning techniques, Pierce trained his rats to associate low-calorie foods with a "diet" taste, and high-calorie foods with a different taste. So, when the rats were fed a high-calorie food that had been flavored with the diet taste, their brains assumed that their bodies were running low on calories. These animals then overate at their next meal in an effort to refuel and make up for the lost energy. "Animals have the ability to sense...
...only that, but most of the krill surrounding the bergs die natural deaths and float to the bottom of the sea--taking with them the globe-warming carbon dioxide pulled from the atmosphere by the phytoplankton they fed on. That CO2, once absorbed, is kept from doing any more harm. It's not enough to cancel out human-generated greenhouse gases, but it doesn't hurt. [This article contains a complex diagram.

Catherine Castrence is not a morning person. So between getting her daughters dressed and fed breakfast, letting the dog out and giving an insulin shot to the family's diabetic cat, the Reston, Va., working mother of two barely had time to pack her kids' lunches before getting them to day camp by 8:00. But this summer she and her husband are outsourcing that particular ritual. Health e-Lunch Kids charges them $4.99 apiece for the homemade, nutritious meals it delivers each day to the local YMCA where Maddy, 9, and Elena, 6, are spending eight weeks...
