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.

The tiny Stingray Nebula unexpectedly appeared in the 1980s is by far the youngest planetary nebula in our sky. But a team of astronomers recently analyzed a more recent image of the nebula, taken in 2016 by Hubble, and found that it has faded significantly and changed shape over the course of just 20 years. If dimming continues at current rates, in 20 or 30 years the Stingray Nebula will be barely perceptible.

The American Association for the Advancement of Science has named four University of Washington faculty members as AAAS Fellows, according to a Nov. 24 announcement from the organization. The four are part of a cohort of 489 new fellows for 2020, which were chosen by their peers for “their scientifically or socially distinguished efforts to advance science or its applications.”

Scientists from around the world, including the University of Washington, have established the Arctic Animal Movement Archive, an online repository for data documenting the movements of animals in the Arctic and Subarctic. With this archive, scientists can share their knowledge and collaborate to ask questions about how animals are responding to a changing climate.

A University of Washington team led by Miqin Zhang, a professor of materials science and engineering and of neurological surgery, has developed a nanoparticle-based drug delivery system that can ferry a potent anti-cancer drug through the bloodstream safely. Their nanoparticle is derived from chitin, a natural and organic polymer that, among other things, makes up the outer shells of shrimp.

A new study led by paleontologists at the University of Washington indicates that the earliest evidence of mammal social behavior goes back to the Age of Dinosaurs. A multituberculate that lived 75.5 million years ago, Filikomys primaevus engaged in multi-generational, group-nesting and burrowing behavior, and possibly lived in colonies.

This fall, about three dozen people signed up to help count the salmon in their local streams and creeks. Recruited by University of Washington Bothell teaching professor Jeff Jensen, these volunteers agree to observe a stream location for at least half an hour per week (while taking coronavirus precautions) to gather vital information about salmon in streams that flow into Lake Washington and the Sammamish River.

In a paper published Sept. 14 in the journal Nature Physics, a team led by the University of Washington reports that carefully constructed stacks of graphene — a 2D form of carbon — can exhibit highly correlated electron properties. The team also found evidence that this type of collective behavior likely relates to the emergence of exotic magnetic states.

Recent honors to UW faculty have come from the American Institute for Aeronautics & Astronautics, the American Society of Composites, the Coalition for Excellence in Maternal and Child Health Epidemiology and the Dance Educators Association of Washington.

The small subpopulation of polar bears in Kane Basin were doing better, on average, in recent years than in the 1990s. The bears are experiencing short-term benefits from thinning and shrinking multiyear sea ice that allows more sunlight to reach the ocean surface, which makes the system more ecologically productive.

Whale Safe — an online tool launched Sept. 17 by scientists at the University of California, Santa Barbara, the University of Washington and other partner institutions — allows users to detect and better protect these endangered animals in the Santa Barbara Channel. It is a mapping and analysis tool to help prevent ships from running into whales.

Dr. Sverre Vedal, UW professor emeritus of environmental and health sciences, served on an expert committee for the National Academies of Science, Engineering and Medicine studying the long-term respiratory health impacts of military service in Southeast Asia.

Researchers at the University of Washington, Portland State University and the University of Oregon have shown that deep-seated landslides in the central Oregon Coast Range are triggered mostly by rainfall, not by large offshore earthquakes. The open-access paper was published Sept. 16 in Science Advances. “Geomorphologists have long understood the importance of rainfall in triggering landslides, and our study is simply driving home just how important it is,” said first author Sean LaHusen, who did the work as part of…

New research shows that a wide variety of marine animals — from vertebrates to crustaceans to mollusks — already inhabit the maximum range of breathable ocean that their physiology will allow. The findings provide a warning about climate change: Since warmer waters will harbor less oxygen, some stretches of ocean that are breathable today for a given species may not be in the future.

The National Science Foundation has awarded $3 million to establish a NSF Research Traineeship at the University of Washington for graduate students in quantum information science and technology. The new traineeship — known as Accelerating Quantum-Enabled Technologies, or AQET — will make the UW one of just “a handful” of universities with a formal, interdisciplinary QIST curriculum.

University of Washington scientists report evidence of a hibernation-like state in Lystrosaurus, an animal that lived in Antarctica during the Early Triassic, some 250 million years ago. The fossils are the oldest evidence of a hibernation-like state in a vertebrate, and indicate that torpor — a general term for hibernation and similar states in which animals temporarily lower their metabolic rate to get through a tough season — arose in vertebrates even before mammals and dinosaurs evolved.

A new study led by researchers at the University of Washington and the University of California, Davis, finds that the success rate of summiting Mount Everest has doubled in the last three decades, even though the number of climbers has greatly increased, crowding the narrow route through the dangerous “death zone” near the summit. However, the death rate for climbers has hovered unchanged at around 1% since 1990.

New research by the University of Minnesota and the University of Washington finds that every six additional ICU beds or seven additional non-ICU beds filled by COVID-19 patients leads to one additional COVID-19 death over the following week. “A spike in hospitalization naturally leads to more deaths, but these deaths may not only come from those who are hospitalized, but also from those who should have been hospitalized but were not,” said co-author Anirban Basu, a UW professor of health…

For nearly 50 years, a statistical omission tantamount to data falsification sat undiscovered in a critical study at the heart of regulating one of the most controversial and widely used pesticides in America. Chlorpyrifos, an insecticide created in the late 1960s by the Dow Chemical Co., has been linked to serious health problems, especially in children. It has been the subject of many lawsuits and banned in Europe and California. The EPA itself nearly banned the chemical, but in 2017 the…
