Brain may play key role in blood sugar metabolism and development of diabetes (11/21/2013)

Brain may play key role in blood sugar metabolism and development of diabetesThe development of diabetes Type 2, the authors argue, requires a failure of both the islet-cell system in the pancreas and a brain-centered system for regulating blood sugar levels. Boosting insulin levels alone will lower glucose levels, but only addresses half the problem. To restore normal glucose regulation requires addressing the failures of the brain-centered system as well. Approaches that target both systems may not only achieve better blood glucose control, but could actually cause diabetes to go into remission. ...> Full Article

Do food blogs serve as a source of nutritionally balanced recipes? (11/16/2013)

More people are cooking at home, and more people are finding their recipes online via food blogs. The photos of dishes posted on the blogs, however, may attract potential cooks more than the nutritional value of the recipes.

How fat could help solve part of the diabetes problem (11/8/2013)

The pancreas is a large organ that wraps around our gut, and produces the exact amount of insulin our bodies need when we eat -- except when we start to develop diabetes, and insulin production slows down. Sydney scientists describe how a fat recycling system within pancreatic "beta cells" determines the amount of insulin they secrete, and so may provide a target for future diabetes therapies. ...> Full Article

Eye tracking technology suggests people 'check out' women at first glance (11/7/2013)

Eye tracking technology suggests people 'check out' women at first glanceEye tracking technology has reconfirmed what women have known all along: that people look at their sexual body parts more and faces less when evaluating their appearance. The study, published today in Springer's journal Sex Roles, was led by Sarah Gervais of the University of Nebraska-Lincoln in the US. It found that especially women with typical hour glass figures or larger breasts, narrower waists, and bigger hips frequently prompted such gazes. ...> Full Article

That allergic reaction to bee stings? It's meant to protect you (11/4/2013)

Allergic reactions to bee stings can be damaging or even deadly, but new evidence from two independent studies of mice reported in the Cell Press journal Immunity on Oct. 24th suggest that the immune response to bee venom and other allergens actually evolved and may continue to serve as a protective defense mechanism. Perhaps they aren't just misdirected immune responses after all. ...> Full Article

New testing strategy detects population-wide vitamin and mineral deficiencies (11/3/2013)

Levels of certain proteins in the bloodstream may be used to estimate levels of essential vitamins and minerals without directly testing for each nutritional factor. Researchers used a new strategy that allowed them to indirectly measure amounts of multiple nutrients in multiple people at the same time, an advance that should make it possible to rapidly detect nutritional deficiencies of an entire population, apply remediation efforts and test their worth within months instead of years. ...> Full Article
