Climate change to fuel increase in human-wildlife conflict, UW biologist says
Climate change is further exacerbating human-wildlife conflicts by straining ecosystems and altering behaviors, both of which can deepen the contacts — and potential competition — between people and animals. In an article published July 30 in the journal Science, Briana Abrahms, an assistant professor of biology at the University of Washington and its Center for Ecosystem Sentinels, calls for expanding research into the many ways that climate change will impact the complex interplay between human activities and wildlife populations.

Scientists model ‘true prevalence’ of COVID-19 throughout pandemic
Two University of Washington scientists have developed a statistical framework that incorporates key COVID-19 data — such as case counts and deaths due to COVID-19 — to model the true prevalence of this disease in the United States and individual states. Their approach, published the week of July 26 in the Proceedings of the National Academy of Sciences, projects that in the U.S. as many as 60% of COVID-19 cases went undetected as of March 7, 2021, the last date for which the dataset they employed is available.

Pandemic-era paleontology: A wayward skull, at-home fossil analyses and a first for Antarctic amphibians
Researchers at the University of Washington and its Burke Museum of Natural History & Culture have discovered the first fossil evidence of an ancient amphibian, Micropholis stowi, from Antarctica. Micropholis lived in the Early Triassic, shortly after Earth’s largest mass extinction. It was previously known only from fossils in South Africa, and its presence in Antarctica has implications for how amphibians adapted to high-latitude regions in this dynamic period of Earth’s history.

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.

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.

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.
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.

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.

Weathering the tough times: Fossil evidence of ‘hibernation-like’ state in 250-million-year-old Antarctic animal
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.

Passing crucial, challenging introductory chemistry course gives biggest boost to underrepresented students
Researchers examined 15 years of records of student performance, education and demographics for chemistry courses at the University of Washington. They found that underrepresented students received lower grades in the general chemistry series compared to their peers and, if the grade was sufficiently low, were less likely to continue in the series and more likely to leave STEM. But if underrepresented students completed the first general chemistry course with at least the minimum grade needed to continue in the series, they were more likely than their peers to continue the general chemistry series and complete this major step toward a STEM degree.

Underrepresented college students benefit more from ‘active learning’ techniques in STEM courses
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…
Climate change at Mount Rainier expected to increase ‘mismatch’ between visitors and iconic wildflowers
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.

Mosquitoes are drawn to flowers as much as people — and now scientists know why
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.

New technique lets researchers map strain in next-gen solar cells
Researchers from the University of Washington and the FOM Institute for Atomic and Molecular Physics in the Netherlands have developed a way to map strain in lead halide perovskite solar cells. Their approach shows that misorientation between microscopic perovskite crystals is the primary contributor to the buildup of strain within the solar cell, which creates small-scale defects in the grain structure, interrupts the transport of electrons within the solar cell, and ultimately leads to heat loss through a process known as non-radiative recombination.
