Study Proves that One Extinction Leads to Another

When a carnivore becomes extinct, other predatory species could soon follow, according to new research.

Scientists have previously put forward this theory, but a University of Exeter team has now carried out the first experiment to prove it.

Published today (15 August 2012) in the Royal Society journal Biology Letters, the study shows how the demise of one carnivore species can indirectly cause another to become extinct. The University of Exeter team believes any extinction can create a ripple effect across a food web, with far-reaching consequences for many other animals. (more…)

Meditation Reduces Loneliness

UCLA study also finds that mindfulness technique benefits immune system

Many elderly people spend their last years alone. Spouses pass and children scatter. But being lonely is much more than a silent house and a lack of companionship. Over time, loneliness not only takes a toll on the psyche but can have a serious physical impact as well.

Feeling lonely has been linked to an increased risk of heart disease, Alzheimer’s disease, depression and even premature death. Developing effective treatments to reduce loneliness in older adults is essential, but previous treatment efforts have had limited success. (more…)

A Hands-on Approach to Treating Patients with Pulmonary Disease

EAST LANSING, Mich. — Researchers at Michigan State University are working to show how a noninvasive, drug-free form of hands-on medical care can help patients with chronic obstructive pulmonary disease improve their breathing.

The team from MSU’s College of Osteopathic Medicine will apply four osteopathic manipulative treatments to a group of patients with moderate to severe chronic obstructive pulmonary disease. One of the most common lung diseases, COPD typically manifests as chronic bronchitis (a long-term cough with mucus) or emphysema (destruction of the lungs over time). (more…)

New Book Explores Noah’s Flood; Says Bible and Science Can Get Along

“I doubt the historic truth about Noah’s Flood will ever be known with certainty. And I don’t think it really matters. The discoveries of science have revealed the world and our universe to be far more spectacular than could have been imagined by Mesopotamian minds. To still see the world through their eyes is to minimize the wonder of creation.”

David Montgomery, “The Rocks Don’t Lie”

David Montgomery is a geomorphologist, a geologist who studies changes to topography over time and how geological processes shape landscapes. He has seen firsthand evidence of how the forces that have shaped Earth run counter to some significant religious beliefs.

But the idea that scientific reason and religious faith are somehow at odds with each other, he said, “is, in my view, a false dichotomy.” (more…)

Male Sandpipers That Sleep Less Have More Sex

A study conducted by scientists at the Max Planck Institute for Ornithology in Seewiesen, Germany has shown that the male members of a sandpiper population who spend less time sleeping are more successful at mating with females and have more offspring.

The sandpiper mating season takes place during the summer in the Arctic Circle, when the sun practically never goes down. Males of the species compete to impress females by fighting with each other, defending territory, and flying over the females while making a hooting sound. (more…)

Global Bullfrog Trade Spreads Deadly Amphibian Fungus Worldwide

ANN ARBOR, Mich.— The global trade in bullfrogs, which are farmed as a food source in South America and elsewhere, is spreading a deadly fungus that is contributing to the decline of amphibians worldwide, according to a University of Michigan biologist and his colleagues. (more…)

For Young Adults, Appearance Matters More than Health, MU Research Suggests

Research inspires interactive theater, opens dialogue

COLUMBIA, Mo. –When it comes to college-age individuals taking care of their bodies, appearance is more important than health, research conducted at the University of Missouri suggests. María Len-Ríos, an associate professor of strategic communication, Suzanne Burgoyne, a professor of theater, and a team of undergraduate researchers studied how college-age women view their bodies and how they feel about media messages aimed at women. Based on focus group research findings, the MU team developed an interactive play about body image to encourage frank discussions about conflicting societal messages regarding weight, values and healthful choices.

“During our focus group conversations, we learned that young people don’t think about nutrition when it comes to eating,” Len-Ríos said. “They think more about calorie-counting, which isn’t necessarily related to a balanced diet.” (more…)

Student Performance Improves When Teachers Given Incentives Upfront

A bonus payment to teachers can improve student academic performance — but only when it is given upfront, on the condition that part of the money must be returned if student performance fails to improve, research at the University of Chicago shows. (more…)
