Police officers and students exhibit an apparent “hierarchy of bias” in making a split-second decision whether to shoot suspects who appear to be wielding a gun or, alternatively, a benign object like a cell phone, research conducted by the University of Colorado Boulder and San Diego State University has found.
Both the police and student subjects were most likely to shoot at blacks, then Hispanics, then whites and finally, in a case of what might be called a positive bias, Asians, researchers found. (more…)
COLUMBUS, Ohio – Warming temperatures in Ohio are a key driver behind changes in the state’s landscape, and non-native plant species appear to be responding more strongly than native wildflowers to the changing climate, new research suggests.
This adaptive nature demonstrated by introduced species could serve them well as the climate continues to warm. At the same time, the non-natives’ potential ability to become even more invasive could threaten the survival of native species already under pressure from land-use changes, researchers say. (more…)
Researchers from North Carolina State University have created flower-like structures out of germanium sulfide (GeS) – a semiconductor material – that have extremely thin petals with an enormous surface area. The GeS flower holds promise for next-generation energy storage devices and solar cells.
“Creating these GeS nanoflowers is exciting because it gives us a huge surface area in a small amount of space,” says Dr. Linyou Cao, an assistant professor of materials science and engineering at NC State and co-author of a paper on the research. “This could significantly increase the capacity of lithium-ion batteries, for instance, since the thinner structure with larger surface area can hold more lithium ions. By the same token, this GeS flower structure could lead to increased capacity for supercapacitors, which are also used for energy storage.” (more…)
EAST LANSING, Mich. — A few minutes of exercise can help children with attention deficit hyperactivity disorder perform better academically, according to a new study led by a Michigan State University researcher.
The study, published in the current issue of the Journal of Pediatrics, shows for the first time that kids with ADHD can better drown out distractions and focus on a task after a single bout of exercise. Scientists say such “inhibitory control” is the main challenge faced by people with the disorder. (more…)
COLUMBUS, Ohio – Transportation practices tend to be more environmentally friendly in wealthier metropolitan areas located within states that mandate comprehensive planning, new research suggests.
The study involved an examination of 225 U.S. metropolitan areas between 1980 and 2008 to gauge how sustainable their transportation practices were and determine what kinds of socioeconomic factors appeared to influence those practices. (more…)
What are the key ingredients to raising successful, self-sufficient offspring? A new life sciences study using 14 years of data on gray wolves in Yellowstone National Park indicates that cooperative group behavior and a mother’s weight are crucial.
“A female’s body weight is key in the survival of her offspring, and cooperation in the protection and feeding of young pups pays off in terms of the production of offspring,” said Robert Wayne, a professor of ecology and evolutionary biology at UCLA and co-author of the new research, published this week in the online edition of the Journal of Animal Ecology.

EAST LANSING, Mich. — Contrary to past research, private school students in India do not outperform their counterparts in public schools, finds a new study by a Michigan State University education researcher.
The study challenges the claim that private schools are superior – a hot issue in India and other developing countries that are expanding K-12 educational offerings. During the past decade, some 40 million children have entered India’s education system, giving rise to a growth in privately run schools. (more…)
EAST LANSING, Mich. — Increasingly, U.S. firms are moving or considering moving their manufacturing operations back to domestic soil from overseas, finds a new study co-authored by a Michigan State University supply chain expert.
Fueling the trend are rising labor costs in emerging countries, high oil prices and increasing transportation costs, global risks such as political instability and other factors, said Tobias Schoenherr.
“Going overseas is not the panacea that it was thought of just a decade or so ago,” said Schoenherr, assistant professor in MSU’s top-ranked Department of Supply Chain Management. “Companies have realized the challenges and thus are moving back to the United States.” (more…)
