Chokeberry extract found to regulate weight gain, blood glucose, and inflammation in rats (July 24, 2010) -- A new study finds that chokeberry extract inhibits weight gain in insulin-resistant animals and modulates multiple genes associated with adipose tissue growth, blood glucose regulation, and inflammatory pathways. ... > full story
Stem cells from surgery leftovers could repair damaged hearts (July 24, 2010) -- Scientists have for the first time succeeded in extracting vital stem cells from sections of vein removed for heart bypass surgery. ... > full story
Diabetes monitoring device benefits not just people but dogs and other animals, too (July 24, 2010) -- A researcher is using a continuous glucose monitoring device -- commonly used in humans with diabetes -- to help treat dogs and other animals. The device, which provides a detailed glucose picture of an animal over several days, will help pet owners manage their pets' diabetes. ... > full story
Academic language impedes students' ability to learn science, expert argues (July 24, 2010) -- Middle and high school students who read fluently in English class and on the Web may find that they cannot understand their science texts. And their science teachers may be ill-prepared to guide them in reading the academic language in which science information is presented. A professor of education and expert on language and literacy development makes the case that students need to be taught academic language to learn science and other subjects. ... > full story
Cancer-metabolism link runs deep in humans, novel network algorithm suggests (July 23, 2010) -- Eighty years ago, the medical establishment believed cancer was caused by a dysfunction of metabolism, but the idea went out of vogue. Now, scientists are again looking at metabolism and its role in cancer and other common diseases. ... > full story
