Browser Plug-in Helps People Balance Their Political News Reading Habits

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…)

Large Bacterial Population Colonized Land 2.75 Billion Years Ago

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…)

The Original Twitter? Tiny Electronic Tags Monitor Birds’ Social Networks

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.

Shrinking Snow Depth on Arctic Sea Ice Threatens Ringed Seal Habitat

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 Make Longer Attempts at Resuscitation Have Higher Survival Rates

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…)

Dinosaur Die Out Might Have Been Second of Two Closely Timed Extinctions

The most-studied mass extinction in Earth history happened 65 million years ago and is widely thought to have wiped out the dinosaurs. New University of Washington research indicates that a separate extinction came shortly before that, triggered by volcanic eruptions that warmed the planet and killed life on the ocean floor.

The well-known second event is believed to have been triggered by an asteroid at least 6 miles in diameter slamming into Mexico’s Yucatán Peninsula. But new evidence shows that by the time of the asteroid impact, life on the seafloor – mostly species of clams and snails – was already perishing because of the effects of huge volcanic eruptions on the Deccan Plateau in what is now India.

UW Deploying Seismic Sensors in Hope of Getting to Bottom of Spokane Quakes

It’s been a decade since a swarm of relatively mild earthquakes shook up parts of Spokane. Now, armed with the right tools, scientists want to find out what was at fault.

“It was always something not as well understood as we thought it should be,” said Douglas Gibbons, a University of Washington researcher in Earth and space sciences, who is guiding installation of strong-motion sensors as part of a project called NetQuakes.

NetQuakes will install a half-dozen seismometers in the Spokane area by the end of June, mostly in volunteers’ homes, to help improve understanding of what lies beneath the city. (more…)
