African-American women who live in rural areas have lower rates of major depressive disorder (MDD) and mood disorder compared with their urban counterparts, while rural non-Hispanic European-American women have higher rates for both than their urban counterparts, according to a new study.

Many of us have a traditional and corporeal perspective on violence. We perceive it as physical threat: the stranger following you home on a dark night; an unprovoked assault in a bar or on an empty train; or the alcohol fueled brawl that breaks out in the Valley in Brisbane on a Friday night.

The secret communication of gibbons has been interpreted for the first time in a study published in the open access journal BMC Evolutionary Biology. The research reveals the likely meaning of a number of distinct gibbon whispers, or 'hoo' calls, responding to particular events and types of predator, and could provide clues on the evolution of human speech.

To reduce the risk of heart disease and stroke, the World Health Organization recommends we consume no more than 2000 mg of sodium a day -- less than a teaspoon of salt.

At the same time, the WHO recommends we consume at least 3510 mg of potassium daily, again to lower our odds of heart disease and stroke.

That's a lot of potassium. Potatoes, for example, are considered to be a relatively potassium-rich food. Yet to get to 3510 mg a day you would have to eat about six potatoes day. Or drink 9 cups of milk. Or eat 2 1/2 cups of beet greens -- a day.

The closures of big-box stores may make it seem like online shopping is killing real-world stores but many shoppers are actually engaging in "web-to-store" buying -- buying in stores after comparing prices online.

New research from Concordia University's John Molson School of Business shows this consumer behavior has important implications for retailers. When setting in-store prices or offering price-matching guarantees, offline retailers should focus more on online retailer ratings than on offering the lowest prices.

"Cheeses with a quality label --for example, those with Protected Designation of Origin (PDO)-- have particular features associated with the raw materials used (Latxa sheep's milk, in the case of Idiazabal cheese) and cultural aspects and/or specific cultural practices (use of raw milk and lamb rennet in paste form) which are preserved and allow products that are organoleptically distinct to be produced," explained Ojeda, co-author of the paper Sensory quality control of cheese: going beyond the absence of defects.

A new study from the University of Michigan Comprehensive Cancer Center finds that many women diagnosed with breast cancer are concerned about the genetic risk of developing other cancers themselves or of a loved one developing cancer.

In a bid to help physicians guide obese and overweight patients who want to try a commercial weight-loss program, a team of Johns Hopkins researchers reviewed 4,200 studies for solid evidence of their effectiveness but concluded only a few dozen of the studies met the scientific gold standard of reliability.

Despite concerns about the increasing costs of treating illnesses like breast cancer, higher treatment costs are linked to better survival rates, according to a study by Yale School of Medicine researchers in the Cancer Outcomes Public Policy and Effectiveness Research (COPPER) Center at Yale School of Medicine and Yale Cancer Center.

The study appears in the April issue of Health Affairs.

New mothers in the Philippines spend more time in the bedroom with their partner in the first few weeks after giving birth than they did before they became pregnant. This might be a type of survival strategy to keep the relationships with the fathers of their new babies alive and well, to ensure continued support for their offspring. So says Michelle Escasa-Dorne of the University of Colorado in the US, after studying how women from a society with a low divorce rate such as the Philippines adapt to being both mothers and lovers. The study appears in Springer's journal Human Nature.

For years, educators, policymakers and institutional leaders have sounded an alarm about the fact that fewer girls and women enter science, technology, engineering and mathematics (STEM) fields than their male peers, and more girls and women leave, but few attempts have been made to identify and rigorously test remedies that can effectively close the gender gap.

Adolescent obesity is a national public health concern and, unchecked, places young people on a trajectory for a variety of health issues as they grow older. A new study from the University of Houston Department of Health and Human Performance (HHP) and Texas Obesity Research Center (TORC) suggests there is a relationship between long-term exposure to three specific types of family stressors and children becoming obese by the time they turn 18 years old.

Those who drink diet soda thinking it will help them shed unwanted belly fat may see their waistlines expand instead. New analyses from an observational study of San Antonio men and women age 65 and older seem to indicate this.
