Ecosystem Effects of Biodiversity Loss Could Rival Impacts of Climate Change, Pollution

ANN ARBOR, Mich.— Loss of biodiversity appears to impact ecosystems as much as climate change, pollution and other major forms of environmental stress, according to a new study from an international research team.

The study is the first comprehensive effort to directly compare the impacts of biological diversity loss to the anticipated effects of a host of other human-caused environmental changes.

The results highlight the need for stronger local, national and international efforts to protect biodiversity and the benefits it provides, according to the researchers, who are based at nine institutions in the United States, Canada and Sweden. (more…)

ANN ARBOR, Mich.— Consumer confidence remained largely unchanged at improved levels in April as consumers were still hopeful about future job gains despite disappointing recent developments, according to economist Richard Curtin, director of the Thomson Reuters/University of Michigan Surveys of Consumers.

The Surveys, conducted by the U-M Institute for Social Research, have been monitoring consumer attitudes and expectations for over 60 years. (more…)

My Fair Physicist? Feminine Math, Science Role Models Do Not Motivate Girls

ANN ARBOR, Mich.— Women who excel in male-dominated science, technology, engineering and mathematic fields are often unjustly stereotyped as unfeminine.

However, if women are perceived as having feminine qualities, their success may actually decrease interest in these fields (usually referred to as “STEM”), particularly among young girls, according to a new University of Michigan study. (more…)

Deep in the Ugandan jungle, David Watts, Yale anthropologist and consultant for new Disney movie “Chimpanzee,” has studied the behavior of humanity’s closest relative. The Ngogo forest boasts one of the largest chimpanzee populations in the world, which not only makes it a great location to film movies, but an unparalleled place to explore chimp […]

Global Health: Students Build Wiki of Medical Devices Designed for Low-Income Countries

ANN ARBOR, Mich.— In parts of the world without reliable electricity, a pedal-powered nebulizer could provide life-saving asthma treatments. Small wax-filled sleeping bags could keep premature infants warm. A salad spinner centrifuge for blood samples could help clinicians diagnose anemia.

University of Michigan researchers have cataloged more than 100 such technologies in a new wiki of medical devices designed for resource-limited settings. The Global Health Medical Device Compendium, an open-source inventory, is hosted by the popular appropriate technology wiki Appropedia. It is expected to serve as an important communication vehicle for end users, non-governmental organizations, researchers and others to help advance such technologies. (more…)

Escalating Arms Race: Predatory Sea Urchins Drive Evolution

ANN ARBOR, Mich.— Nature teems with examples of evolutionary arms races between predators and prey, with the predator species gradually evolving a new mode of attack for each defensive adaptation that arises in the prey species.

These adaptations are often portrayed as reciprocal, with prey and predator acting as two sides in an endless evolutionary tug of war known as co-evolution. (more…)

Many Young People Would Rather Surf the Web than Drive a Car

ANN ARBOR, Mich.— More young adults today would rather hit the information highway than the open highway, say University of Michigan researchers.

In a new study in the journal Traffic Injury Prevention, Michael Sivak and Brandon Schoettle of the U-M Transportation Research Institute found that having a higher proportion of Internet users was associated with lower licensure rates among young persons.

And this is just not in the United States; it’s happening in other countries, too. (more…)

YouTube Campaign Videos More Positive Than Television Ads

ANN ARBOR, Mich.—YouTube campaign videos are more positive than ads aired on television, a new University of Michigan study shows.

YouTube videos are more positive because they are narrowly targeted to the highly informed, high motivated, usually supportive people who view a candidate’s online video, said Rob Salmond, the study’s author and assistant professor of political science. (more…)
