A new analysis of 2.5-billion-year-old rocks from Australia finds that volcanic eruptions may have stimulated population surges of marine microorganisms, creating the first puffs of oxygen into the atmosphere. This would change existing stories of Earth’s early atmosphere, which assumed that most changes in the early atmosphere were controlled by geologic or chemical processes.

New analysis of landmark scurvy study leads to update on vitamin C needs

It was wartime and food was scarce. Leaders of England’s effort to wage war and help the public survive during World War II needed to know: Were the rations in lifeboats adequate for survival at sea? And, among several experiments important for public as well as military heath, how much vitamin C did a person need to avoid the deadly disease scurvy? In one experiment at the Sorby Research Institute in Sheffield, called the “shipwreck” experiment, volunteers were fed only…

Now how did that get up there? New study sheds light on development and evolution of dolphin, whale blowholes

Image of a dolphin swimming in the ocean

New research by scientists at the University of Washington and Duke University is shedding light on how the nasal passage of dolphins and whales shifts during embryonic development from emerging at the tip of the snout to emerging at the top of the head as a blowhole. The findings, published July 19 in the Journal of Anatomy, are an integrative model for this developmental transition for cetaceans.

Drier, warmer night air is making some Western wildfires more active at night

Firefighters have reported that Western wildfires are starting earlier in the morning and dying down later at night, hampering their ability to recover and regroup before the next day’s flareup. A study by University of Washington and U.S. Forest Service scientists shows why: The drying power of nighttime air over much of the Western U.S. has increased dramatically in the past 40 years.

Superflares may be less harmful to exoplanets than previously thought, study shows

Astronomers have long suspected that superflares, extreme radiation bursts from stars, can cause lasting damage to the atmospheres — and thus habitability — of exoplanets. A new study published in the Monthly Notices of the Royal Astronomical Society reports that they pose only a limited danger to planetary systems.

Fine particulate air pollution associated with higher risk of dementia

Pollution map Puget Sound region

Using data from two large, long-running study projects in the Puget Sound region — one that began in the late 1970s measuring air pollution and another on risk factors for dementia that began in 1994 — University of Washington researchers identified a link between air pollution and dementia. In the UW-led study, a small increase in the levels of fine particle pollution (PM2.5 or particulate matter 2.5 micrometers or smaller) averaged over a decade at specific addresses in the Seattle…

New report: State of the science on western wildfires, forests and climate change

wildfire in washington's methow valley

Seeing the urgent need for change, a team of scientists from leading research universities, conservation organizations and government laboratories across the West has produced a synthesis of the scientific literature that clearly lays out the established science and strength of evidence on climate change, wildfire and forest management for seasonally dry forests. The goal is to give land managers and others across the West access to a unified resource that summarizes the best-available science so they can make decisions about how to manage their landscapes.

Climate change to fuel increase in human-wildlife conflict, UW biologist says

A herd of African elephants

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.

UW to lead new NSF institute for using artificial intelligence to understand dynamic systems

Purple and white lines that are tracing the shape of the UW W.

The UW will lead a new artificial intelligence research institute that will focus on fundamental AI and machine learning theory, algorithms and applications for real-time learning and control of complex dynamic systems, which describe chaotic situations where conditions are constantly shifting and hard to predict.

Possible future for Western wildfires: Decade-long burst, followed by gradual decline

cubes of forest landscape up in flames

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.

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.

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.

Study model explores impact of police action on population health

A specific police action, an arrest or a shooting, has an immediate and direct effect on the individuals involved, but how far and wide do the reverberations of that action spread through the community? What are the health consequences for a specific, though not necessarily geographically defined, population? The authors of a new UW-led study looking into these questions write that because law enforcement directly interacts with a large number of people, “policing may be a conspicuous yet not-well understood…

The region north of Greenland and the Canadian Arctic has been termed the Last Ice Area, where sea ice will remain the longest in summertime, providing a refuge for ice-dependent Arctic species. But conditions last summer show that parts of this region are already experiencing less summer ice due to climate change.

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.

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.

Drug rebates for insurers tied to higher costs for patients, especially the uninsured

Federal agencies that regulate drug pricing and healthcare insurance are concerned that an industry practice of using rebates to lower drug costs for insurers has led to increases in list prices and out-of-pockets costs for patients. To investigate whether patients with or without insurance were paying more because of rebates to insurers, researchers led by the University of Washington examined cost and price data on more than 400 branded drugs. The study found that rebates were associated with increases in…

Communication technology, study of collective behavior must be ‘crisis discipline,’ researchers argue

Our ability to confront global crises, from pandemics to climate change, depends on how we interact and share information. 

Social media and other forms of communication technology restructure these interactions in ways that have consequences. Unfortunately, we have little insight into whether these changes will bring about a healthy, sustainable and equitable world. As a result, researchers now say that the study of collective behavior must rise to a “crisis discipline,” just like medicine, conservation and climate science have done, according to a new paper published June 14 in the Proceedings of the National Academy of Sciences.

Edge of Pine Island Glacier’s ice shelf is ripping apart, causing key Antarctic glacier to gain speed

ridged ice and airplane wing

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.
