Possible future for Western wildfires: Decade-long burst, followed by gradual decline
A model of the eastern California forests of the Sierra Nevada looks at the longer-term future of wildfires under future climate change scenarios. Results show an initial roughly decade-long burst of wildfire activity, followed by recurring fires of decreasing area — a pattern that could apply to other hot, dry forests in the West.

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.

Older workers needed for UW study on worker safety during COVID-19 pandemic
Public health researchers have learned a lot about how the pandemic affected workers and exacerbated existing health disparities that exist in many communities. However, there’s still a lot we don’t know about the experience of workers deemed essential in the food industry and who were at higher risk of contracting COVID-19, such those working in…

New 3D images of shark intestines show they function like Nikola Tesla’s valve
For more than a century, researchers have relied on flat sketches of sharks’ digestive systems to discern how they function — and how what they eat and excrete impacts other species in the ocean. Now, researchers have produced a series of high-resolution, 3D scans of intestines from nearly three dozen shark species that will advance the understanding of how sharks eat and digest their food.

Air pollution from wildfires impacts ability to observe birds
Researchers from the University of Washington provide a first look at the probability of observing common birds as air pollution worsens during wildfire seasons. They found that smoke affected the ability to detect more than a third of the bird species studied in Washington state over a four-year period. Sometimes smoke made it harder to observe birds, while other species were actually easier to detect when smoke was present.

Researchers discover yessotoxins, produced by certain phytoplankton, to be a culprit behind summer mass shellfish mortality events in Washington
Back in the summers of 2018 and 2019, the shellfish industry in Washington state was rocked by mass mortalities of its crops. Now, researchers think they have figured out why: high concentrations of yessotoxinss, which are produced by blooms of certain phytoplankton. The researchers’ findings were published last month in the open-access journal Harmful Algae.

Edge of Pine Island Glacier’s ice shelf is ripping apart, causing key Antarctic glacier to gain speed
Satellite images show that from 2017 to 2020, Pine Island Glacier’s ice shelf lost about one-fifth of its area, mostly in three dramatic breaks. This caused the glacier to speed up by 12%, hastening its downward motion and boosting its contribution to rising seas.
Smartphone camera can illuminate bacteria causing acne, dental plaques
Researchers at the University of Washington have developed a method that uses smartphone-derived images to reveal potentially harmful bacteria on skin and in oral cavities. Their approach can visually identify microbes on skin contributing to acne and slow wound healing, as well as bacteria in the oral cavity that can cause gingivitis and dental plaques.

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.

Ice core data show why, despite lower sulfur emissions in U.S. and Western Europe, air pollution is dropping more slowly
Ice core data from Greenland shows why air pollution is dropping more slowly than sulfur emissions reductions. As cloud droplets become less acidic, the chemical reaction that turns sulfur dioxide into sulfate aerosol gets more efficient. The new results can improve the models that project air quality and climate change.
FASER is born: new experiment will study particles that interact with dark matter
The newest experiment at CERN, the European Organization for Nuclear Research, is now in place at the Large Hadron Collider in Geneva. FASER, or Forward Search Experiment, was approved by CERN’s research board in March 2019. Now installed in the LHC tunnel, this experiment, which seeks to understand particles that scientists believe may interact with dark matter, is now undergoing tests before data collection commences next year.

Deep earthquakes within the Juan de Fuca plate produce few aftershocks
In the Cascadia subduction zone, medium- and large-sized “intraslab” earthquakes, in which the slip happens within the oceanic plate and below the continental plate, will likely produce only a few detectable aftershocks, according to a new study from the University of Washington and the U.S. Geological Survey.

First results from Muon g-2 experiment strengthen evidence of new physics
The first results from the Muon g-2 experiment hosted at Fermi National Accelerator Laboratory show fundamental particles called muons behaving in a way not predicted by the Standard Model of particle physics. These results confirm an earlier experiment of the same name performed at Brookhaven National Laboratory. Combined, the two results show strong evidence that our best theoretical model of the subatomic world is incomplete. One potential explanation would be the existence of undiscovered particles or forces.

‘A turning point’: UW Population Health Initiative’s pandemic grants changed how the university works
A year ago, seemingly overnight, streets emptied, shops boarded up, grocery shelves were cleared, schools closed and the University of Washington led universities nationwide in moving all instruction online. Nearly all of us disappeared inside, stunned and staring out at a world suddenly paralyzed by something we’d only seen in movies or read about in books:…

‘By-the-wind sailor’ jellies wash ashore in massive numbers after warmer winters
Thanks to 20 years of observations from thousands of citizen scientists, University of Washington researchers have discovered distinct patterns in the mass strandings of by-the-wind sailor jellies. Specifically, large strandings happened simultaneously from the northwest tip of Washington south to the Mendocino coast in California, and in years when winters were warmer than usual.

How five global regions could achieve a successful, equitable ‘Blue Economy’
The future of an equitable and sustainable global ocean, or “Blue Economy,” depends on more than natural or technological resources. A new study finds that socioeconomic and governance conditions such as national stability, corruption and human rights greatly affect different regions’ ability to achieve a Blue Economy — one that is socially equitable, environmentally sustainable and economically viable.
