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.

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.

More US adults carrying loaded handguns daily, study finds

New research led by the University of Washington finds that the number of U.S. adult handgun owners carrying a loaded handgun on their person doubled from 2015 to 2019, and that a larger proportion of handgun owners carried handguns in states with less restrictive carrying regulations.

Fundraising effort to restore, reimagine historic ASUW Shell House is in full swing

Perched on the southeast corner of the University of Washington campus, where the Montlake Cut meets Union Bay, the ASUW Shell House looks as vulnerable as it does majestic. Over the course of a century, the structure built as a critical wartime post later was the home to a group of rowers who captured the nation’s imagination before becoming an all-but-forgotten artifact of the past. Now, propelled by a wave of renewed interest, the 12,000-square-foot wooden structure is the focus of an $18.5 million campaign that will restore and renovate the space.

Infants less likely to contract COVID, develop severe symptoms than household caregivers

In one of the first studies to explore how COVID-19 specifically affects older infants, researchers from the University of Washington and at institutions at four other locations in the Western and Southern U.S. found that the number of infected people in a household was the factor most closely linked with the infant’s likelihood of being infected.

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.
