They are the portals to the cell, gateways through which critical signals and chemicals are exchanged between living cells and their environments. But these gateways -- proteins that span the cell membrane and connect the world outside the cell to its vital inner workings "“ remain, for the most part, black boxes with little known about their structures and how they work. They are of intense interest to scientists as they are the targets on which many drugs act, but are notoriously...

Psychological well-being is powerful enough to counteract the pull of socioeconomic status on the long-term health of the disadvantaged, according to a study by researchers at the University of Wisconsin-Madison. Lack of education is a powerful predictor of future poor health and a relatively early death. But among people whose formal education ended with a high school diploma or less, positive psychological characteristics such as meaningful relationships with others and a sense of purpose...

In cold weather, many children can't resist breathing onto a window and writing in the condensation. Now imagine the window as an electronic device platform, the condensation as a special conductive gas, and the letters as lines of nanowires. A team led by University of Wisconsin-Madison Materials Science and Engineering Professor Chang-Beom Eom has demonstrated methods to harness essentially this concept for broad applications in nanoelectronic devices, such as next-generation memory or tiny...

The mathematical skills of boys and girls, as well as men and women, are substantially equal, according to a new examination of existing studies in the current online edition of journal Psychological Bulletin. One portion of the new study looked systematically at 242 articles that assessed the math skills of 1,286,350 people, says chief author Janet Hyde, a professor of psychology and women's studies at the University of Wisconsin-Madison. These studies, all published in English between 1990...

Widespread planting of genetically modified Bt corn throughout the Upper Midwest has suppressed populations of the European corn borer, a major insect pest of corn, with the majority of the economic benefits going to growers who do not plant Bt corn, reports a multistate team of scientists in the Oct. 8 edition of the journal Science. In Wisconsin, 75 percent of the $325 million cumulative economic benefit linked to Bt corn's pest suppression between 1996-2009 went to non-Bt corn growers....

Ambitious plans to expand acreage of bioenergy crops could have a major impact on birds in the Upper Midwest, according to a study published today (Oct. 4) in the online edition of the Proceedings of the National Academy of Sciences (PNAS). Combining data from bird surveys and land usage, two University of Wisconsin-Madison researchers calculated changes in the number of bird species after widespread planting of bioenergy crops. The study compared two approaches to bioenergy feedstocks:...

Typically, monkeys don't know what to make of a mirror. They may ignore it or interpret their reflection as another, invading monkey, but they don't recognize the reflection as their own image. Chimpanzees and people pass this "mark" test "” they obviously recognize their own reflection and make funny faces, look at a temporary mark that the scientists have placed on their face or wonder how they got so old and grey. For 40 years, scientists have concluded from this type of behavior...

Engineering researchers from Tufts University, the University of Wisconsin-Madison and Harvard University have demonstrated the low-temperature efficacy of an atomically dispersed platinum catalyst, which could be suitable for on-board hydrogen production in fuel-cell-powered vehicles of the future. An alternative to copper, which under certain conditions can ignite spontaneously, the platinum-based catalyst is highly active and stable. The researchers' understanding of the structure and...

A modest moss gives insight into global carbon cycling The diversity of life that can be seen in environments ranging from the rainforests of the Amazon to the spring blooms of the Mohave Desert is awe-inspiring. But this diversity would not be possible if the ancestors of modern plants had just stayed in the water with their green algal cousins. Moving onto dry land required major lifestyle changes to adapt to this new "hostile" environment, and in turn helped change global climate and...
