Evolution is written all over your face

Posted: 11 Jan 2012 07:37 PM PST

Why are the faces of primates so dramatically different from one another? Biologists serving as "evolutionary detectives" studied the faces of 129 adult male primates from Central and South America, and offer answers. These faces evolved over at least 24 million years.

Clue as to why alcohol is addicting: Scientists show that drinking releases brain endorphins

A diet rich in slowly digested carbs reduces markers of inflammation in overweight and obese adults

Posted: 11 Jan 2012 12:40 PM PST

Among overweight and obese adults, a diet rich in slowly digested carbohydrates, such as whole grains, legumes and other high-fiber foods, significantly reduces markers of inflammation associated with chronic disease, according to a new study. Such a "low-glycemic-load" diet, which does not cause blood-glucose levels to spike, also increases a hormone that helps regulate the metabolism of fat and sugar.

Deep brain stimulation -- also known as DBS -- is effective at improving motor symptoms and quality of life in patients with advanced Parkinson's disease, according to new research.

Lab-made tissue picks up the slack of Petri dishes in cancer research

New research, using oral cancer cells in a three-dimensional model of lab-made tissue, demonstrates that previous models used to examine cancer may not be complex enough to accurately mimic the true cancer environment.

New model for epidemic contagion

Neuroscientists have discovered how the sense of touch is wired in the skin and nervous system. The new findings open new doors for understanding how the brain collects and processes information from hairy skin.

Global study sheds light on role of exercise, cars and televisions on the risk of heart attacks

Posted: 11 Jan 2012 06:06 AM PST

A worldwide study has shown that physical activity during work and leisure time significantly lowers the risk of heart attacks in both developed and developing countries. Ownership of a car and a television was linked to an increased risk of heart attacks, particularly in low- and middle-income countries.

A penny-per-ounce tax on sugar-sweetened beverages keeps the doctor away and saves money

Posted: 09 Jan 2012 06:20 PM PST

Over the past 10 years, Americans drank more sugar-sweetened beverages than ever making these drinks the single largest dietary factor in the current obesity epidemic. In a latest study, researchers estimated that if a higher, penny-per-ounce tax were imposed on sugar-sweetened beverages, it would result in an approximately 15 percent reduction in consumption and reduce the prevalence of obesity, diabetes, and cardiovascular disease.
