Survey: Americans struggle with science; respect scientists

While most Americans could be a bit more knowledgeable in the ways of science, a majority are interested in hearing about the latest scientific breakthroughs and think highly of scientists.

This is according to a survey of more than 2,200 people conducted by the National Science Foundation, one that is conducted every two years and is part of a report – Science and Engineering Indicators – that the National Science Board provides to the president and Congress. (more…)

With Their Amazing Necks, Ants Don’t Need “High Hopes” to Do Heavy Lifting

Ants can lift up to 5,000 times their own body weight, new study suggests

COLUMBUS, Ohio — High hopes may help move a rubber tree plant (as the old song goes), but the real secret to the ant’s legendary strength may lie in its tiny neck joint.

In the Journal of Biomechanics, researchers report that the neck joint of a common American field ant can withstand pressures up to 5,000 times the ant’s weight. (more…)

Decoding dengue and West Nile: Researchers take steps toward control of growing public health problems

ANN ARBOR — Dengue fever and West Nile fever are mosquito-borne diseases that affect hundreds of millions of people worldwide each year, but there is no vaccine against either of the related viruses.

A team of scientists at the University of Michigan and Purdue University has discovered a key aspect both to how the viruses replicate in the cells of their host and how they manipulate the immune system as they spread. (more…)

Drug Trafficking Leads to Deforestation in Central America

‘Drug policy is conservation policy,’ researchers say

COLUMBUS, Ohio – Add yet another threat to the list of problems facing the rapidly disappearing rainforests of Central America: drug trafficking.

In an article in the journal Science, seven researchers who have done work in Central America point to growing evidence that drug trafficking threatens forests in remote areas of Honduras, Guatemala, Nicaragua and nearby countries. (more…)

Weapons tied to repeat domestic abuse

Women are up to 83 percent more likely to experience repeat abuse by their male partners if a weapon is used in the initial abuse incident, according to a new study that has implications for victims, counselors and police.

Michigan State University researcher Amy Bonomi and colleagues studied the domestic abuse police reports of nearly 6,000 couples in Seattle during a two-year period. An estimated one in four women in the United States experience domestic violence at least once in their lifetime. (more…)

Helping adolescents understand the consequences of risky sexual behavior

Both parents and health care providers wonder: What is the best way to get through to adolescents about the dangers of risky sexual behavior? Research by investigators from Yale School of Medicine and the Yale play2PREVENT Lab finds that both positive and negative messaging may influence adolescent behavior. The study is published online in the journal Health Education Research.

The researchers write that 48% of high school students have had sex, and 6% had sex by the age of 13. Beginning sexual activity at an early age increases the risk of multiple partners, unwanted pregnancy, and sexually transmitted infections. A full half of all new sexually transmitted infections in the United States occur in individuals aged 15 to 25. (more…)

Salamander Population Size Helps Predict Health of Forest Ecosystems and Inform Forest Management Decisions, MU Study Finds

Researchers suggest a balance between timber harvest and conservation biology

COLUMBIA, Mo. – Woodland salamanders are small, lungless amphibians that live in moist, forest habitats throughout the U.S. and the world. Salamanders often serve as vital links in forest food chains; their population size and recovery from major disturbances can help predict the health of forest ecosystems. Now, researchers at the University of Missouri have determined that salamander population size reflects forest habitat quality and can predict how ecosystems recover from forest logging activity. MU researchers believe these findings can be translated to other species within forest ecosystems throughout the world.

“One of our primary interests is in conservation of amphibians and the habitats that they utilize,” said Ray Semlitsch, Curators’ Professor of biological sciences in the College of Arts and Science at MU. “We are trying to understand how land use, and particularly forest management, affects the survival of amphibians on the landscape. We also determined that salamander recovery—or the amount of time it takes for salamanders to repopulate a cut forest area—can help forest managers determine appropriate logging schedules.” (more…)
