Astronomers document the rise and fall of a rarely observed stellar dance

An image of stars in the night sky, showing a particularly bright binary at the center called HS Hydra.

Astronomers have catalogued 126 years of changes to a binary star system called HS Hydrae. Analyzing observations from astro-photographic plates in the late 1800s to TESS observations in 2019, they show that the two stars in HS Hydrae began to eclipse each other starting around a century ago, peaking in the 1960s. The degree of eclipsing then plummeted over the course of just a half century, and will cease around February 2021.

pink piece of salmon

A study co-authored by UW’s Sunny Jardine finds that farmed Atlantic salmon, often labeled and sold as Pacific salmon or rainbow trout, is the second-most-consumed mislabeled seafood product in the U.S. Although not the most frequently mislabeled seafood, salmon’s popularity means it has one of the biggest environmental impacts.

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.

A team led by scientists at the University of Washington and the University of California, San Diego has discovered that cowpeas — a type of bean plant — harbor receptors on the surface of their cells that can detect a compound in caterpillar saliva and initiate anti-herbivore defenses.


Tire-related chemical is largely responsible for adult coho salmon deaths in urban streams

A team led by researchers at UW Tacoma, UW and Washington State University Puyallup has discovered a chemical that kills coho salmon in urban streams before the fish can spawn.


Leaving so soon? Unusual planetary nebula fades mere decades after it arrived

An image of the Stingray Nebula taken in 2016 by NASA's Hubble Space Telescope

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.

A diagram showing the overlap between the atomic layout of sheets of 2D materials

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.

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.

Most landslides in western Oregon triggered by heavy rainfall, not big earthquakes

bare slope and mountains in distance

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…


Marine animals live where ocean is most ‘breathable,’ but ranges could shrink with climate change

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.
