Ice core data show why, despite lower sulfur emissions in U.S. and Western Europe, air pollution is dropping more slowly

The air in the United States and Western Europe is much cleaner than even a decade ago. Low-sulfur oil standards and regulations on power plants have successfully cut sulfate concentrations in the air, reducing the fine particulate matter that harms human health and cleaning up the environmental hazard of acid rain. Despite these successes, sulfate levels in the atmosphere have declined more slowly than sulfur dioxide emissions, especially in wintertime.

Timing is everything: ShakeAlert comes to Washington May 4

A hand holds a phone lock screen with an emergency alert that reads Earthquake detected! Drop, cover, hold on. Protect yourself -USGS ShakeAlert

It could happen any time, any day. Multiple seismometers — scientific instruments that measure ground motion — detect a 7.0 magnitude earthquake in Washington, Oregon or California. Seismic waves move fast, but seismometers move faster: The data zips from seismometer to processing center at the speed of light (670,616,629 mph), where algorithms calculate the area and intensity of shaking and sound an emergency warning to phones moments before shaking arrives: Drop.

Working towards equity and inclusion is a community effort, and one that requires active participation and push for change. The Equity & Inclusion (E&I) Committee is at the helm of advancing diversity, equity, inclusion and justice initiatives at the School of Aquatic and Fishery Sciences (SAFS), and they have been working to make the School and community a more welcoming place.

Leveraging the tectonic laboratory of the Cascadia subduction zone, the University of Washington today announced a new effort to best understand how to study and live with the threats of earthquakes, tsunamis, volcanos, landslides and other seismic hazards. Dubbed the GeoHazards Initiative, the interdisciplinary work aims to develop and promote the adoption of early detection systems both on land and at sea to help prevent the loss of human life and property.

Thousands of baby sea stars born at UW lab are sign of hope for endangered species

Research assistant Fleur Anteau checks on year-old juvenile sunflower sea stars in the UW lab as research scientist Jason Hodin examines month-old sea star larvae under a microscope.

Just a few days shy of the first day of spring, scientists at Friday Harbor Laboratories on San Juan Island had reason to celebrate. Dozens of juvenile sea stars, no bigger than a poppy seed, had successfully metamorphosed from floating larvae to mini star — the important first step toward becoming an adult. Between now and then, these sunflower sea stars, the largest sea star species in the world, will grow up to 24 arms and a colorful body the size of a serving platter.
