Marine organisms use previously undiscovered receptors to detect, respond to light
Single-celled organisms in the open ocean use a diverse array of genetic tools to detect sunlight, even in tiny amounts, and respond. The discovery of these new genetic “light switches” could also aid in the field of optogenetics, in which a cell’s function can be controlled with light exposure.

In Brazil, many smaller dams disrupt fish more than large hydropower projects
A new University of Washington paper quantifies the tradeoffs between hydroelectric generation capacity and the impacts on river connectivity for thousands of current and projected future dams across Brazil. The findings confirm that small hydropower plants are far more responsible for river fragmentation than their larger counterparts due to their prevalence and distribution.
On nights before a full moon, people go to bed later and sleep less, study shows
Sleep cycles in people oscillate during the 29.5-day lunar cycle: In the days leading up to a full moon, people go to sleep later in the evening and sleep for shorter periods of time. The team, led by researchers at the University of Washington, observed these variations in both the time of sleep onset and the duration of sleep in urban and rural settings — from Indigenous communities in northern Argentina to college students in Seattle, a city of more than 750,000. They saw the oscillations regardless of an individual’s access to electricity, though the variations are less pronounced in individuals living in urban environments.
Purported phosphine on Venus more likely to be ordinary sulfur dioxide, new study shows
A University of Washington-led team has revisited and comprehensively reinterpreted the radio telescope observations underlying a widely reported 2019 claim that phosphine gas was present in the atmosphere of Venus. In a paper accepted to the Astrophysical Journal, they report that sulfur dioxide, a common gas in the atmosphere of Venus, is likely what was detected instead of phosphine.

The 7 rocky planets orbiting TRAPPIST-1 may be made of similar stuff
A study accepted by the Planetary Science Journal shows that the planets of the TRAPPIST-1 system share similar densities. That could mean they all contain roughly the same ratio of materials thought to be common to rocky planets, such as iron, oxygen, magnesium and silicon — though they appear to differ notably from Earth.

Researchers use lasers and molecular tethers to create perfectly patterned platforms for tissue engineering
Researchers at the University of Washington have developed a technique to modify naturally occurring biological polymers with protein-based biochemical messages that affect cell behavior. Their approach, published the week of Jan. 18 in the Proceedings of the National Academy of Sciences, uses a near-infrared laser to trigger chemical adhesion of protein messages to a scaffold made from biological polymers such as collagen, a connective tissue found throughout our bodies.

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

Bait and switch: Mislabeled salmon, shrimp have biggest environmental toll
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.

NSF-funded deep ice core to be drilled at Hercules Dome, Antarctica
Antarctica’s next deep ice core, a 1.5-mile core reaching back to 130,000-year-old ice, will be carried out by a multi-institutional U.S. team led by UW’s Eric Steig. The site hundreds of miles from today’s coastline could provide clues to the most recent collapse of the West Antarctic Ice Sheet.

Military flights biggest cause of noise pollution on Olympic Peninsula
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.

Researchers discover how bean plants fend off famished foes
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
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.

Break it up: Polymer derived from material in shrimp’s shells could deliver anti-cancer drugs to tumor sites
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.
Flying through wildfire smoke plumes could improve smoke forecasts
The biggest study yet of West Coast wildfire plumes shows how a smoke plume’s chemistry changes over time. Results suggest current models may not accurately predict the air quality downwind of a wildfire.
No social distancing in the Cretaceous: New study finds earliest evidence for mammal social behavior
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.

All together now: Experiments with twisted 2D materials catch electrons behaving collectively
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.
