Ice cores show even dormant volcanoes leak abundant sulfur into the atmosphere
Non-erupting volcanoes leak a surprisingly high amount of sulfur-containing gases. A Greenland ice core shows that volcanoes quietly release at least three times as much sulfur into the Arctic atmosphere than estimated by current climate models. Aerosols are the most uncertain aspect of current climate models, so better estimates could improve the accuracy of long-term projections.

How did the Butterfly Nebula get its wings? It’s complicated
Something is amiss in the Butterfly Nebula. When a team led by astronomers at the University of Washington compared two exposures of this planetary nebula that had been taken by the Hubble Space Telescope in 2009 and 2020, they saw dramatic changes in the material within its “wings.” As the team will report on Jan. 12 at the 241st meeting of the American Astronomical Society in Seattle, powerful winds are apparently driving complex alterations of material within the Butterfly Nebula, behavior not seen in planetary nebulae to date. The researchers want to understand how such activity is possible from what should be a “sputtering, largely moribund star with no remaining fuel.”

Old and new stars paint very different pictures of the Triangulum galaxy
On Jan. 11 at the 241st meeting of the American Astronomical Society in Seattle, a team led by scientists at the University of Washington and the Center for Computational Astrophysics reported something unexpected about the distinct populations of stars that make up the Triangulum galaxy: In this satellite galaxy, a close companion of the much larger Andromeda galaxy, old and new stars occur in separate parts of the galaxy’s structure, something not seen in galaxies like our own and so far not reporter for other satellite galaxies.

The seven-year photobomb: Distant star’s dimming was likely a ‘dusty’ companion getting in the way, astronomers say
University of Washington astronomers were on the lookout for “stars behaving strangely” when an automated alert from pointed them to Gaia17bpp, a star that had gradually brightened over a 2 1/2-year period. But follow-up analyses indicated that Gaia17bpp wasn’t changing. Instead, the star is likely part of a rare type of binary system. Its apparent brightening was the end of a years-long eclipse by an unusual, “dusty” stellar companion.
Plastic pollution in the oceans is an equity issue, says UW-led report
A recent report and upcoming virtual event looks at the unequal effect of marine plastics on different communities. The international report led by UW’s Yoshitaka Ota covers topics ranging from the COVID-19 pandemic’s impact on plastic pollution to a critique of Coca-Cola’s waste initiative.

Climate ‘presses’ and ‘pulses’ impact Magellanic penguins — a marine predator — with guidance for conservationists
Climate change will reshape ecosystems through two types of events: short-term, extreme events — or “pulses” — and long-term changes, or “presses.” Understanding the effects of presses and pulses is essential as conservationists and policymakers try to preserve ecosystems and safeguard biodiversity. Researchers at the University of Washington have discovered how different presses and pulses impacted Magellanic penguins — a migratory marine predator — over nearly four decades and found that, though individual presses and pulses impacted penguins in a variety of ways, both were equally important for the future survival of the penguin population. They also found that these types of climate changes, taken together, are leading to an overall population decline at their historically largest breeding site.
Warming oceans have decimated marine parasites — but that’s not a good thing
Save the … parasites? Analyzing 140 years of parasite abundance in fish shows dramatic declines, especially in parasites that rely on three or more host species. The decline is linked to warming ocean temperatures. Parasitic species might be in real danger, researchers warn — and that means not just fewer worms, but losses for the entire ecosystem.

Signals from the ionosphere could improve tsunami forecasts
An underwater volcanic eruption in January 2022 created ripple effects throughout the world’s atmosphere and oceans. University of Washington scientists analyzed that event to show how GPS signals could help monitor future volcanoes and tsunamis.
Trouble falling asleep at night? Chase that daytime light, study shows
A study measuring the sleep patterns of students at the University of Washington found that students fell asleep later in the evening and woke up later in the morning during winter, when daylight hours on the UW’s Seattle campus are limited and the skies are notoriously overcast. Researchers believe the students’ natural circadian clocks were being “pushed back” or delayed in winter because they were not getting enough exposure during the day to natural light, and that getting more daytime light exposure can help reverse this.

UW brings field geology to students with ‘Virtual Field Geology’
UW’s Virtual Field Geology project has many goals: to make geology field experiences accessible to more people; to document geological field sites that may be at risk from erosion or development; to offer virtual “dry run” experiences; and to allow scientific collaborators to do virtual visits to a field site together. While the pandemic brought new urgency to the project, its developers believe it’s part of a “new normal” for geology research and education.
NASA’s James Webb Space Telescope shows how several stars ‘stirred up’ the Southern Ring Nebula
In a study published Dec. 8 in Nature Astronomy, an international research team, led by Orsola De Marco of Macquarie University in Sydney, Australia, analyzed 10 highly detailed exposures taken by the JWST of the Southern Ring Nebula. Their calculations show the central star that ejected the expanding nebula gas was originally three times the mass of the sun, and that unseen companions shaped the nebula’s intricate features.

New blood test can detect ‘toxic’ protein years before Alzheimer’s symptoms emerge, study shows
Researchers at the University of Washington have detected “toxic” small aggregates of a particular protein in the blood of individuals with Alzheimer’s disease, as well as in individuals who showed no signs of cognitive impairment at the time the blood sample was taken, but who developed it at a later date. This blood test picks up oligomers — or small, misfolded aggregates — of the amyloid beta protein, which scientists believe triggers the development of Alzheimer’s.

Strongest Arctic cyclone on record led to surprising loss of sea ice
The strongest Arctic cyclone ever observed struck in January 2022. A new analysis led by the University of Washington shows that while forecasts accurately predicted the massive storm, models seriously underestimated its impact on sea ice. Results suggest how forecast models for a changing Arctic Ocean could improve.

Study reveals how ancient fish colonized the deep sea
A new University of Washington-led study reports that throughout Earth’s ancient history, there were several periods of time when many fish actually favored the cold, dark, barren waters of the deep sea instead of shallow ocean waters that are warm and full of resources.
Permanent daylight saving time would reduce deer-vehicle collisions, study shows
University of Washington researchers found that adopting permanent daylight saving time in the United States would reduce deer-vehicle collisions and likely prevent an estimated 36,550 deer deaths, 33 human deaths, 2,054 human injuries and $1.19 billion in costs each year. Deer-vehicle collisions would decrease under permanent DST because skies would be brighter later into the evening.

Study suggests La Niña winters could keep on coming
Forecasters are predicting a “three-peat La Niña” this year. This will be the third winter in a row that the Pacific Ocean has been in a La Niña cycle, something that’s happened only twice before in records going back to 1950. A new study of temperature patterns in the tropical Pacific Ocean suggests that climate change is, in the short term, favoring La Niñas.

Heat-related mortality risk is widespread across Washington state, study shows
Heat-related deaths occur across Washington state, even in regions with typically milder climates. This is the most extensive study yet of heat-related mortality in Washington state, and the first to look beyond the major population to and include rural areas. Researchers used statistical methods to uncover “hidden” deaths that may have listed something else, like illness or a chronic disease, as the primary cause.
UW joins industry-academia alliance to accelerate research in neuroscience
The University of Washington has joined the Alliance for Therapies in Neuroscience (ATN), a long-term research partnership between academia and industry geared to transform the fight against brain diseases and disorders of the central nervous system. Launched in 2021 by the University of California, San Francisco, UC Berkeley, Genentech — a member of the Roche group — and Roche Holding AG, the ATN seeks to accelerate the development of new therapies for a broad range of brain and central nervous system conditions.

Deepest scientific ocean drilling effort sheds light on Japan’s next ‘big one’
A 2018 expedition that drilled farther into the seafloor than ever before — almost 2 miles — sought to take measurements of stress as close as possible to a tectonic fault off the coast of Japan. Surprisingly, the researchers found little built-up tectonic stress. The findings could help to better understand earthquakes in subduction zones around the world.

These female hummingbirds evolved to look like males — apparently to evade aggression
1 in 5 adult female white-necked jacobin hummingbirds look like males. New research from the University of Washington shows that this is a rare case of “deceptive mimicry” within a species: Females with male-like plumage are trying to pass themselves off as males, and as a result receive a benefit in the form of reduced aggression from males.

‘Dangerous’ and ‘extremely dangerous’ heat stress to become more common by 2100
A new study projects the number of days with “dangerous” and “extremely dangerous” mixtures of heat and humidity by the end of this century. Even if global warming is limited to 2 degrees Celsius, results show that deadly heat waves will become much more common in the mid-latitudes, and many tropical regions will experience “dangerous” heat for about half the year.

New study challenges old views on what’s ‘primitive’ in mammalian reproduction
Which group of mammals has the more “primitive” reproductive strategy — marsupials, with their short gestation periods, or humans and other placental mammals, which have long gestation periods? For decades, biologists viewed marsupial reproduction as “more primitive.” But University of Washington scientists have discovered that a third group of mammals, the long-extinct multituberculates, had a long gestation period like placental mammals. Since multituberculates split off from the rest of the mammalian lineage before placentals and marsupials had even evolved, these findings question the view that marsupials were “less advanced” than their placental cousins.
