*MU researchers find that up to 70 percent of Amazonian cultures practiced multiple paternity*

COLUMBIA, Mo. – In modern culture, it is not considered socially acceptable for married people to have extramarital sexual partners. However, in some Amazonian cultures, extramarital sexual affairs were common, and people believed that when a woman became pregnant, each of her sexual partners would be considered part-biological father. Now, a new University of Missouri study published in the journal Proceedings of the National Academy of Science has found that up to 70 percent of Amazonian cultures may have believed in the principle of multiple paternity.

“In these cultures, if the mother had sexual relations with multiple men, people believed that each of the men was, in part, the child’s biological father,” said Robert Walker, assistant professor of Anthropology in the College of Arts and Science. “It was socially acceptable for children to have multiple fathers, and secondary fathers often contributed to their children’s upbringing.” (more…)

COLUMBIA, Mo. – For some women, the effects of breast cancer, the most common cancer affecting women, do not end when they leave the hospital. Now, researchers in the University of Missouri School of Health Professions have studied the lives of breast cancer patients following chemotherapy and found that their environments and available support systems help determine the quality of their lives.

“A lot of times people get mentally and emotionally ready to deal with chemotherapy and they receive a lot of support during that time,” said Stephanie Reid-Arndt, an assistant professor of health psychology in the School of Health Professions. “Then they go home and everyone feels like it’s over, but the patients still have worries and fears about the changes they’ve been through and what it means for the future.” (more…)

COLUMBIA, Mo. – Celebrity journalism is often considered to be without merit, discounted due to its sensational details and lack of news value. MU researchers now say that celebrity journalism may be an underappreciated way to communicate health messages. In a recent award-winning paper, Amanda Hinnant, assistant professor of magazine journalism in the University of Missouri School of Journalism, found some readers of celebrity health stories report that the stories have an impact on their own behavior and how they discuss health issues.

COLUMBIA, Mo.– It might seem obvious that a dinosaur’s leg bone connects to the hip bone, but what came between the bones has been less obvious. Now, researchers at the University of Missouri and Ohio University have found that dinosaurs had thick layers of cartilage in their joints, which means they may have been considerably taller than previously thought. The study is being published this week in the journal PLoS-ONE (Public Library of Science). (more…)

COLUMBIA, Mo. – Although obesity is a major risk factor for disease, much of the threat may be associated with the metabolic (or cardiometabolic) syndrome, a cluster of risk factors related to diabetes and heart disease. Losing weight can improve health and reduce many of these risk factors. However, many people struggle to keep the weight off long-term. Now, researchers at the University of Missouri have found that people who perform resistance training while regaining weight can help maintain strides in reducing their risks for chronic disease.

COLUMBIA, Mo. — When people discuss climate change, they usually think of impacts above ground, such as atmospheric changes, rising ocean levels, or melting glaciers. Less attention is paid to the effects right under their feet. Now, with the help of a $1.2 million grant from the federal Plant Feedstock Genomics for Bioenergy program, University of Missouri researchers are peering underground to see how climate change affects plant roots.
