An online study of eligible voters around the country revealed that preferences for whites over blacks among the least politically-partisan voters are strong enough to have substantial impact on their presidential candidate preference.
Among these voters, race biases against Barack Obama could produce as much as a 20 percent gap in the popular vote in a contest that would otherwise be equal. (more…)
A current focus in global health research is to make medical tests that are not just cheap, but virtually free. One such strategy is to start with paper – one of humanity’s oldest technologies – and build a device like a home-based pregnancy test that might work for malaria, diabetes or other diseases.
A University of Washington bioengineer recently developed a way to make regular paper stick to medically interesting molecules. The work produced a chemical trick to make paper-based diagnostics using plain paper, the kind found at office supply stores around the world. (more…)
As the U.S. presidential election approaches, many voters become voracious consumers of online political news. A tool by a University of Washington researcher tracks whether all those articles really provide a balanced view of the debate – and, if not, suggests some sites that offer opinions from the other side of the political spectrum.
Balancer, a free plug-in for Google’s Chrome browser, was developed this summer by Sean Munson, a new UW assistant professor of Human Centered Design and Engineering. The tool analyzes a person’s online reading habits for a month and calculates the political bias in that behavior. It then suggests sites that represent a different point of view and continues to monitor reading behavior and offer feedback. (more…)
There is evidence that some microbial life had migrated from the Earth’s oceans to land by 2.75 billion years ago, though many scientists believe such land-based life was limited because the ozone layer that shields against ultraviolet radiation did not form until hundreds of millions years later.
But new research from the University of Washington suggests that early microbes might have been widespread on land, producing oxygen and weathering pyrite, an iron sulfide mineral, which released sulfur and molybdenum into the oceans. (more…)
If two birds meet deep in the forest, does anybody hear? Until now, nobody did, unless an intrepid biologist was hiding underneath a bush and watching their behavior, or the birds happened to meet near a research monitoring station. But an electronic tag designed at the University of Washington can for the first time see when birds meet in the wild.
A new study led by a biologist at Scotland’s University of St. Andrews used the UW tags to see whether crows might learn to use tools from one another. The findings, published last week in Current Biology, supported the theory by showing an unexpected amount of social mobility, with the crows often spending time near birds outside their immediate family.

As part of a commitment to create opportunities for 300 million youth around the world during the next three years, Microsoft announces support for five national U.S. nonprofits that focus on youth causes. Here’s a look at how these organizations are making a difference.
REDMOND, Wash. — As part of the launch of the Microsoft YouthSpark initiative, Microsoft announced national partnerships with five major nonprofit organizations with missions to give youth the skills, education and job training they need to succeed: Boys & Girls Clubs of America, City Year, Junior Achievement USA (JA), Network for Teaching Entrepreneurship (NFTE) and Year Up.
On the surface, the nonprofit grants aim to bolster programs that help youth learn important 21st-century skills, find jobs and connect with caring adult mentors. (more…)
As sea ice in the Arctic continues to shrink during this century, more than two thirds of the area with sufficient snow cover for ringed seals to reproduce also will disappear, challenging their survival, scientists report in a new study.
The ringed seal, currently under consideration for threatened species listing, builds caves to rear its young in snow drifts on sea ice. Snow depths must be on average at least 20 centimeters, or 8 inches, to enable drifts deep enough to support the caves. (more…)
Hospitals that continue CPR longer have better survival rates from cardiac arrests, according to a study published online Sept. 5 in The Lancet. The findings challenge the assumption that, if a pulse is not restored soon, continuing resuscitation efforts is futile.
The results also showed that patients who recovered after an extended CPR effort were no more likely to suffer brain damage than are patients revived after a shorter effort. (more…)
