Procedure done in pigs could potentially detect heart disease early in humans

COLUMBIA, Mo. — Heart disease is a leading cause of death throughout the world. Doctors say that it is important to detect heart disease early before it becomes too serious. Now, researchers at the University of Missouri have found a way that they believe could help detect heart disease before it progresses too far as well as identify patients who are at risk for strokes.

In a study published in Medicine and Science in Sports and Exercise, Isabelle Masseau, an assistant teaching professor in the MU College of Veterinary Medicine, found that she could use targeted micro-bubbles to detect artery inflammation in pigs. She says that this procedure may help detect patients with heart disease or who are at risk for strokes before those ailments become too serious by monitoring artery inflammation, as that is an early warning sign of health problems. She says this procedure may also help monitor the effectiveness of artery inflammation treatments. (more…)

U of T Researchers Uncover Major Source of Evolutionary Differences among Species

TORONTO, ON – University of Toronto Faculty of Medicine researchers have uncovered a genetic basis for fundamental differences between humans and other vertebrates that could also help explain why humans are susceptible to diseases not found in other species.

Scientists have wondered why vertebrate species, which look and behave very differently from one another, nevertheless share very similar repertoires of genes. For example, despite obvious physical differences, humans and chimpanzees share a nearly identical set of genes. (more…)

AMHERST, Mass. – Though it seems like an oxymoron, Arctic hurricanes happen, complete with a central “eye,” extreme low barometric pressure and towering 30-foot waves that can sink small ships and coat metal platforms with thick ice, threatening oil and gas exploration. Now climate scientists at the University of Massachusetts Amherst and in England report the first conclusive evidence that Arctic hurricanes, also known as polar lows, play a significant role in driving ocean water circulation and climate.

Results point to potentially cooler conditions in Europe and North America in the 21^st century than other models predict. (more…)

Father’s Death Affects Early Adolescents’ Futures in Developing World, Says MU Anthropologist

Knowledge of effects could lead to better assistance for youths

COLUMBIA, Mo. – A father’s death can have long-term effects on a child’s later success in life and can be particularly harmful if the father passes away during a child’s late childhood or early adolescence, according to new research by a University of Missouri anthropologist. Recognizing the impact that a father’s death can have on adolescents could lead to improved counseling and assistance programs, especially for needy families in the developing world.

“Certain negative effects of a father’s death can’t be compensated for by the mother or other relatives,” said Mary Shenk, assistant professor of anthropology in MU’s College of Arts and Science. “The loss of a father can result in lower adult living standards for the bereaved children. Not only is a child emotionally affected, but the lack of a father’s earning power can cause children to get married younger or drop out of school in order to work.” (more…)

Monkey See, Monkey Do: Visual Feedback Is Necessary for Imitating Facial Expressions

Research using new technology shows that our ability to imitate facial expressions depends on learning that occurs through visual feedback.

Studies of the chameleon effect confirm what salespeople, tricksters, and Lotharios have long known: Imitating another person’s postures and expressions is an important social lubricant.

But how do we learn to imitate with any accuracy when we can’t see our own facial expressions and we can’t feel the facial expressions of others? (more…)

Research may help protect rare primate from illegal trades

A venomous primate with two tongues would seem safe from the pet trade, but the big-eyed, teddy-bear face of the slow loris (Nycticebus sp.) has made them a target for illegal pet poachers throughout the animal’s range in southeastern Asia and nearby islands. (more…)
