Research has shown convincing evidence that dietary patterns practiced during adulthood are important contributors to age-related cognitive decline and dementia risk. An article published in Annals of the New York Academy of Sciences highlights information on the benefits of diets high in fruit, vegetables, cereals and fish and low in saturated fats in reducing dementia risk.

Adults with diabetes are especially sensitive to the foods they eat with respect to cognitive function. Specifically, an adult with diabetes will experience a decline in memory function after a meal, especially if simple carbohydrate foods are consumed.

World Community Grid is the largest public humanitarian grid with more than 333,000-plus members and links to more than 780,000 computers. Eight projects have been run on World Community Grid to date, including protein folding and FightAIDS@Home, which completed five years of HIV/AIDS research in just six months.

Now Canadian researchers expect to accelerate the war on cancer by tapping into that global network of hundreds of thousands of people who volunteer their idle computer time to tackle some of the world’s most complex problems.

Scientists from P&G Beauty announced that they successfully sequenced the complete genome for Malassezia globosa (M. globosa), a naturally occurring fungus responsible for the onset of dandruff and other skin conditions in humans.

Dandruff and seborrheic dermatitis affect more than 50 percent of the human population. Despite the role of Malassezia in these and other common skin diseases, including eczema, atopic dermatitis and psoriasis, little was known about the fungus at the molecular level until this study. In addition, understanding of Malassezia’s genetic make-up may help scientists reevaluate the parameters that have historically been used to classify fungal organisms.

For the past four years, Gabor Forgacs, Professor of Physics at University of Missouri-Columbia, has been working to refine the process of “printing” tissue structures of complex shape with the aim of eventually building human organs. In a new study, the research team led by Forgacs determined that the process of building such structures by printing does not harm the properties of the composing cells and the process mimics the naturally occurring biological assembly of living tissues.

The reason; each year, pharmaceutical companies invest millions of dollars to test drugs, many of which will never reach the market because of side effects found only during human clinical trials. At the same time, the number of patients waiting for organ transplants continues to increase.

Individual brain chemistry and genes could be key to understanding why some people become addicted to nicotine and why the chemical compound's effects appear to diminish at night, University of Colorado at Boulder researchers say.

"The depth of a person's addiction to nicotine appears to depend on his or her unique internal chemistry and genetic make-up," said lead author Jerry Stitzel, an assistant professor in CU-Boulder's department of integrative physiology and researcher with CU-Boulder's Institute for Behavioral Genetics.

He and his team set out to evaluate the effects of nicotine over the course of a day by examining mice that could make and "recognize" melatonin, a powerful hormone and antioxidant, and others that could not.
