Students from different backgrounds in the United States enter college with equal interest in STEM fields — science, technology, engineering and mathematics. But that equal interest does not result in equal outcomes. Six years after starting an undergraduate STEM degree, roughly twice as many white students finished it compared to African American students. A new study by researchers at the University of Washington shows that teaching techniques in undergraduate STEM courses can significantly narrow gaps in course performance between students…

The wildflowers of Mount Rainier’s subalpine meadows, which bloom once the winter snowpack melts, are a major draw for the more than 1 million visitors to this national park in Washington state each spring and summer. But by the end of this century, scientists expect that snow will melt months earlier due to climate change. New research led by the University of Washington shows that, under those conditions, many visitors would miss the flowers altogether.

Late last year, news broke that the star Betelgeuse was fading significantly, ultimately dropping to around 40% of its usual brightness. The activity fueled popular speculation that the red supergiant would soon explode as a massive supernova. But astronomers have more benign theories to explain the star’s dimming behavior. And scientists at the University of Washington and Lowell Observatory believe they have support for one of them: Betelgeuse isn’t dimming because it’s about to explode — it’s just dusty. In…

P. Dee Boersma, a UW professor of biology and director of the Center for Ecosystem Sentinels, is a finalist for the 2020 Indianapolis Prize for conservation, to be awarded later this year by the Indianapolis Zoological Society. Sue Moore, a scientist with the center and a UW affiliate professor of biology and of aquatic and fishery sciences, has won the 2020 IASC Medal, also known as the Arctic Medal, from the International Arctic Science Committee.

It’s the year 2020, and where two or more are gathered, it seems, there is a podcast. Given the level of creativity among University of Washington faculty and staff, it’s no surprise that many high-quality podcasts are now being produced on campus. Here’s a look at three podcasts being created by UW departments or people, including a couple that have been underway for quite a while. UW Notebook will occasionally report on campus podcasts and ask a few questions of…

Victoria Meadows, professor of astronomy at the University of Washington and director of the UW’s Virtual Planetary Laboratory, talks about how upcoming missions like the James Webb Space Telescope will be able to characterize the atmospheres of potentially Earth-like exoplanets and may even detect signs of life. Meadows is delivering a talk on this subject on Feb. 15, 2020 at the American Association for the Advancement of Science annual meeting in Seattle.

Scientists and physicians have long known that immune cells migrate to the site of an infection, which individuals experience as inflammation — swelling, redness and pain. Now, researchers at the University of Washington and Northwestern University have uncovered evidence that this gathering is not just a consequence of immune activation. Immune cells count their neighbors before deciding whether or not the immune system should kick into high gear.

A team of chemical engineers has developed a new way to produce medicines and chemicals and preserve them using portable “biofactories” embedded in water-based gels known as hydrogels. The approach could help people in remote villages or on military missions, where the absence of pharmacies, doctor’s offices or even basic refrigeration makes it hard to access critical medicines and other small-molecule compounds. The team — led by Hal Alper, a professor of chemical engineering at the University of Texas, and…

Despite their reputation as blood-suckers, mosquitoes actually spend most of their time drinking nectar from flowers. Scientists have identified the chemical cues in flowers that stimulate mosquitoes’ sense of smell and draw them in. Their findings show how cues from flowers can stimulate the mosquito brain as much as a warm-blooded host — information that could help develop less toxic repellents and better traps.

When nearly one million common murres died at sea and washed ashore from California to Alaska in 2015 and 2016, it was unprecedented. Scientists from the University of Washington, the U.S. Geological Survey and others blame an unexpected squeeze on the ecosystem’s food supply, brought on by a severe and long-lasting marine heat wave known as “the blob.”

If you fear a trip to the dentist, you are among a majority of adults that report moderate to high levels of anxiety related to dental care, according to a review of research. And, if you’re afraid of getting into a dental chair, you are more likely to avoid going and are at risk of oral and overall health problems, such as worsened cardiovascular disease. Studies show that, of those adults with such fear, more than 70% say they started…

To better understand large, disruptive snowstorms, a University of Washington atmospheric scientist will lead a NASA field campaign this winter to fly through major snowstorms along the East Coast. The multi-institutional team will observe snow as it forms in clouds to help with satellite monitoring of snowfall and ultimately improve forecasts.

Joyce Yen — director of the University of Washington’s ADVANCE Center for Institutional Change, an NSF-funded body to promote female STEM faculty on campus — recently worked with the Heising-Simons Foundation to dismantle bias and promote diversity in a prominent grant that the Foundation awards to postdoctoral researchers in planetary science. In this Q&A, Yen shares the many, sometimes counterintuitive ways bias can work against goals toward greater diversity, equity and inclusion in STEM fields.

Using a mathematical framework with roots in artificial intelligence and robotics, UW researchers were able to uncover the process of how a person makes choices in groups. And, they also found they were able to predict a person’s choice more often than more traditional descriptive methods.

UW researchers have found that air pollution from electricity generation emissions in 2014 led to about 16,000 premature deaths in the continental U.S. In many states, the majority of the health impacts came from emissions originating in other states.

With a $106 million gift from the Weill Family Foundation, UC Berkeley, UC San Francisco and the University of Washington have launched the Weill Neurohub, an innovative research network that will forge and nurture new collaborations between neuroscientists and researchers working in an array of other disciplines — including engineering, computer science, physics, chemistry and mathematics — to speed the development of new therapies for diseases and disorders that affect the brain and nervous system.
