Fighting fire with fire in the Methow Valley

Editor’s note: Each year wildfires impact the landscape and change the way of life for many communities around the world. Last fall, UW News went to the Methow Valley — the heart of fire country — to learn more about how UW’s experts play a role in shaping how we fight and live with fires here in Washington. Here’s one story: WINTRHOP, Wash.

Seven species more invasive than a murder hornet

When it comes to invasive species, we tend to hear most about the ones that are the most sensational or scariest to human beings, even though their ecological impact is pretty minor. We have all heard a lot of buzz from Blaine, Washington surrounding the giant Asian hornet (commonly referred to as a “murder hornet” in popular media), but its impact remains to be seen.

Mobile app for boaters expands to Washington state

Washington Sea Grant, in partnership with the Washington State Parks Clean Vessel Act (CVA) Grant Program, is excited to announce that Pumpout Nav, a free iOS and Android app for boaters, has expanded to Washington. Boaters can now use the interactive tool to find nearly 200 pumpout and portable toilet dump stations in Washington, in addition to hundreds of pumpout and floating restroom facilities in Oregon and California.

February lockdown in China caused a drop in some types of air pollution, but not others

Pollution over Shanghai, China in October 2019.

Atmospheric scientists have analyzed how the February near-total shutdown of mobility affected the air over China. Results show a striking drop in nitrogen oxides, a gas that comes mainly from tailpipes and is one component of smog. Learning how behavior shifts due to the COVID-19 pandemic affect air quality is of immediate importance, since the virus attacks human lungs. The event is also a way for Earth scientists to study how the atmosphere responds to sudden changes in emissions.

Systemic racism has consequences for all life in cities

Social inequalities, specifically racism and classism, are impacting the biodiversity, evolutionary shifts and ecological health of plants and animals in our cities. That’s the main finding of a review paper led by the University of Washington, with co-authors at the University of California, Berkeley, and University of Michigan, which examined more than 170 published studies and analyzed the influence of systemic inequalities on ecology and evolution.
