UW researchers investigated disparities in exposure to six major air pollutants in 1990, 2000 and 2010 by comparing models of air pollution levels to census data. While overall pollutant concentrations have decreased since 1990, people of color are still more likely to be exposed to all six pollutants than white people, regardless of income level, across the continental United States.

Public health messages such as in the image below — designed to reduce parents’ purchases of sugar-sweetened beverages marketed as fruit drinks for children — convinced a significant percentage of parents to avoid those drinks, according to a study by researchers at the University of Washington and the University of Pennsylvania. The UW-led study set out to assess the effect of culturally tailored countermarketing messages on drink choices, similar to stark anti-smoking campaigns, and involved more than 1,600 Latinx parents…

In a rare stroke of luck, researchers from the University of Washington, the University of California, Berkeley, and the University of California, Santa Barbara, were able to track a group of black-tailed deer during and after California’s third-largest wildfire, the 2018 Mendocino Complex Fire. The megafire, which torched more than 450,000 acres in northern California, burned across half of an established study site, making it possible to record the movements and feeding patterns of deer before, during and after the fire.

Two University of Washington scientists have developed a statistical framework that incorporates key COVID-19 data — such as case counts and deaths due to COVID-19 — to model the true prevalence of this disease in the United States and individual states. Their approach, published the week of July 26 in the Proceedings of the National Academy of Sciences, projects that in the U.S. as many as 60% of COVID-19 cases went undetected as of March 7, 2021, the last date for which the dataset they employed is available.

Researchers from the University of Washington provide a first look at the probability of observing common birds as air pollution worsens during wildfire seasons. They found that smoke affected the ability to detect more than a third of the bird species studied in Washington state over a four-year period. Sometimes smoke made it harder to observe birds, while other species were actually easier to detect when smoke was present.

The U.S. Geological Survey, the University of Washington-based Pacific Northwest Seismic Network, and state emergency managers on Tuesday, May 4, will activate the system that sends earthquake early warnings throughout Washington state. This completes the rollout of ShakeAlert, an automated system that gives people living in Washington, Oregon and California advance warning of incoming earthquakes.

Lightning strikes in the Arctic tripled from 2010 to 2020, a finding University of Washington researchers attribute to rising temperatures due to human-caused climate change. The results, researchers say, suggest Arctic residents in northern Russia, Canada, Europe and Alaska need to prepare for the danger of more frequent lightning strikes.

A year ago, seemingly overnight, streets emptied, shops boarded up, grocery shelves were cleared, schools closed and the University of Washington led universities nationwide in moving all instruction online. Nearly all of us disappeared inside, stunned and staring out at a world suddenly paralyzed by something we’d only seen in movies or read about in books: a global pandemic. Then came the questions: How long will the virus keep us inside and shut down? What will happen to the people who…

Human-caused warming is responsible for increasing the risk of a glacial outburst flood from Peru’s Lake Palcacocha, threatening the city below. This study is the first to directly link climate change with the risk of flooding from glacial lakes, which are growing in number and size worldwide.

Sleep cycles in people oscillate during the 29.5-day lunar cycle: In the days leading up to a full moon, people go to sleep later in the evening and sleep for shorter periods of time. The team, led by researchers at the University of Washington, observed these variations in both the time of sleep onset and the duration of sleep in urban and rural settings — from Indigenous communities in northern Argentina to college students in Seattle, a city of more than 750,000. They saw the oscillations regardless of an individual’s access to electricity, though the variations are less pronounced in individuals living in urban environments.

A new University of Washington study provides the first look at how much noise pollution is impacting the Olympic Peninsula. The paper found that aircraft were audible across a large swath of the peninsula at least 20% of weekday hours, or for about one hour during a six-hour period. About 88% of all audible aircraft in the pre-pandemic study were military planes.

Cost of living is up in all Washington counties, for families of all sizes, according to the 2020 Self-Sufficiency Standard for Washington State, a report that identifies the amount of income needed to support families of various sizes without additional help from the government, community or other personal resources.

When exploring data on Washington workers during the pandemic — demographics, working conditions, wages and benefits, and risks of exposure to disease — the authors of a new report found that women hold two-thirds of the jobs in the harshest category of work. “The big takeaway from our research,” said David West, a co-author of the report and an analyst at the Washington Labor Education and Research Center, “is how particularly women are working under precarious conditions — a large…

Roughly one-third of young males and 1 in 10 females in rural communities have carried a handgun, reports a new University of Washington study. And, the study found, many of those rural kids started carrying as early as the sixth grade. “This is one of the first longitudinal studies of rural adolescent handgun carrying across multiple states in the U.S. It provides evidence that youth handgun carrying in these settings is not uncommon,” said lead author Dr. Ali Rowhani-Rahbar, a UW…

A Seattle family of four must bring in $75,000 annually to pay for basic housing, food, transportation and health and child care – an increase of 62 percent since 2006, based on a new report from the University of Washington. The city’s escalating cost of living may not be a surprise. But across the state, the amount of money required to make ends meet for two adults, a preschooler and a school-age child has risen as well, according to the…
