What motivates people to walk and bike? It varies by income
The built environment influences decisions to walk or bike differently for lower- and higher-income groups, UW researchers have found. Neighborhood density, accessible destinations and fewer vehicles were associated with more walking and biking in lower-income groups, while neighborhood attractiveness was relevant for higher-income groups.

No easy answers in UW study of legal marijuana’s impact on alcohol use
Does legal marijuana tempt pot users to consume more alcohol — or are they likely to opt for cannabis instead of chardonnay? A University of Washington team of researchers sought to address those questions in the context of evolving marijuana policies in the United States. Their findings, published online Dec. 21 in the journal Alcoholism:…

UW Tacoma geoscientist tracked risks from deadly 2015 Nepal earthquake
When an earthquake struck Nepal in late April 2015, thousands of lives were lost in the initial disaster.

Trees either hunker down or press on in a drying and warming western U.S. climate
Two University of Washington researchers have uncovered details of the radically divergent strategies that two common tree species employ to cope with drought in southwestern Colorado. As they report in a new paper in the journal Global Change Biology, one tree species shuts down production and conserves water, while the other alters its physiology to continue growing and using water.

UW project focuses on fines and fees that create ‘prisoners of debt’
Criminals are meant to pay their debts to society through sentencing, but a different type of court-imposed debt can tie them to the criminal justice system for life and impact their ability to move forward with their lives. Though debtors’ prisons were eliminated in the United States almost two centuries ago, a modern-day version exists…

UW researchers estimate poverty and wealth from cell phone metadata
In developing or war-ravaged countries where government censuses are few and far between, gathering data for public services or policymaking can be difficult, dangerous or near-impossible. Big data is, after all, mainly a First World opportunity. But cell towers are easier to install than telephone land lines, even in such challenged areas, and mobile or…

Since the first laser was invented in 1960, they’ve always given off heat. University of Washington researchers are the first to solve a decades-old puzzle — figuring out how to make a laser refrigerate water and other liquids.
Microbes that are key indicators of Puget Sound’s health in decline
Paleontologists with the University of Washington’s Burke Museum of Natural History and Culture find that tiny organisms called foraminifera have a big story to tell about the health of Puget Sound. Two recent studies about the health of Bellingham Bay and inlets in the Bremerton area found the diversity and number of foraminifera — single-celled marine organisms that live on the sea floor — deteriorated significantly. The decline of these microscopic organisms is consistent with the deterioration of snails and other larger marine animals, even though analysis showed a reduction of chemical pollutants in Bellingham Bay and Bremerton over the same period of time.

Oceans — and ocean activism — deserve broader role in climate change discussions
When President Barack Obama visited the shrinking Exit Glacier in September, he pointed to a very obvious sign of our warming planet literally at his feet. Less visible, but perhaps more indelible, signs of changing climate lie in the oceans. A University of Washington researcher argues in the journal Science that people — including world…
‘Pale orange dot’: Early Earth’s haze may give clue to habitability elsewhere in space
An atmospheric haze around a faraway planet — like the one which probably shrouded and cooled the young Earth — could show that the world is potentially habitable, or even be a sign of life itself.

Now you see it: cloaking technology arrives sooner than UW mathematician expected
In science, decades can pass between a proposed theory and its real-world application. That is precisely what University of Washington mathematics professor Gunther Uhlmann was expecting when he and three colleagues proposed a means to develop an electromagnetic wormhole in a 2007 paper in Physical Review Letters. Their theoretical wormhole — an invisible tube for…
UW scientists are the first to simulate 3-D exotic clouds on an exoplanet
A nearby exoplanet has an atmosphere that might be similar to Earth’s before life evolved. In an attempt to simulate the structure of this exoplanet’s atmosphere, UW researchers became the first to simulate three-dimensional exotic clouds on another world.
