An analysis of the relationship between diet and beak shape among waterfowl not only shows that feeding is likely the major influence that fits the bill, but also suggests that early birds of the order were likely more duck-like than goose-like. (more…)

ANN ARBOR — On opposite sides of the globe over millions of years, the snakes of North America and Australia independently evolved similar body types that helped them move and capture prey more efficiently.
Snakes on both continents include stout-bodied, highly camouflaged ambush predators, such as rattlesnakes in North America and death adders in Australia. There are slender, fast-moving foragers on both continents, as well as small burrowing snakes. (more…)
ANN ARBOR — People setting a goal to lose weight in 2013 may want to first ask themselves if diet or exercise is more important to success.
Whether a person believes obesity is caused by overeating or by a lack of exercise can predict whether he or she will gain or lose weight, according to University of Michigan research to be published in the journal Psychological Science.
With two-thirds of the adult U.S. population classified as overweight or obese and similar numbers in many developed nations, obesity has become an important health concern. (more…)
COLUMBUS, Ohio – Taking enough omega-3 fatty acid supplements to change the balance of oils in the diet could slow a key biological process linked to aging, new research suggests.
The study showed that most overweight but healthy middle-aged and older adults who took omega-3 supplements for four months altered a ratio of their fatty acid consumption in a way that helped preserve tiny segments of DNA in their white blood cells. (more…)
COLUMBUS, Ohio – New research suggests that there could be health hazards associated with consuming excessive amounts of beta-carotene.
This antioxidant is a naturally occurring pigment that gives color to foods such as carrots, sweet potatoes and certain greens. It also converts to vitamin A, and foods and supplements are the only sources for this essential nutrient.
But scientists at Ohio State University have found that certain molecules that derive from beta-carotene have an opposite effect in the body: They actually block some actions of vitamin A, which is critical to human vision, bone and skin health, metabolism and immune function. (more…)
Do smarter people live longer and better lives? Are certain personality types more prone to premature death than are others? As our population continues to age in dramatic numbers, these questions become increasingly relevant. A new report in Psychological Science in the Public Interest, a journal of the Association for Psychological Science, provides an overview of research on possible associations between intelligence and personality traits and various health outcomes.
Although there is not much evidence to date that links intelligence with cancer, low intelligence has been shown to be related to increased risk of hospital admission and death due to cardiovascular disease. In addition, lower intelligence is associated with a greater incidence of accidents and risk of death by homicide than is higher intelligence. (more…)
We are what our father ate before we were born! An international team of researchers has found that a father’s diet while growing up can affect his offspring’s future health.
Researchers, who specifically looked at the effects of paternal diet in their study, have discovered that a father’s lifestyle can be passed down to next generation because it “reprogrammes” his genes. (more…)
*University of Missouri scientists create a vegetable oil from soybeans that is much healthier than others*
COLUMBIA, Mo. — Years of research has proven that saturated and trans fats clog arteries, make it tough for the heart to pump and are not valuable components of any diet. Unfortunately, they are contained in many foods. Now, a University of Missouri research team has developed a soybean which produces oil that is naturally low in saturated and trans fats.
