Scientists have discovered something unexpected about 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 its structure, something not seen in galaxies like our own and so far not reporter for other satellite galaxies.
Astronomers discovered that the star Gaia17bpp gradually brightened over a 2 1/2-year period. But follow-up analyses revealed that the star itself wasn’t changing. Instead, it's 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.
A new report and upcoming international virtual event addresses the unequal burden of marine plastics on different communities. The illustrated report includes case studies from around the world and recommends future changes.
Researchers have discovered how short- and long-term climate trends have impacted Magellanic penguins — a migratory marine predator — over nearly four decades. Though individual events impacted penguins in a variety of ways, both were equally important for the future survival of this population.
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.
A new study reports that college students in Seattle fall asleep later and wake up later in winter, likely because -- as the study also found -- in winter the students received less daylight exposure. The researcher say that outside in the morning, even on cloudy days, is the best way to prevent this circadian rhythm "delay."
The 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.
Researchers can detect small "toxic" aggregates of a particular protein in the blood of individuals with Alzheimer's disease and 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.
The strongest Arctic cyclone ever observed struck in January 2022. A new analysis shows that while forecasts accurately predicted the massive storm, models seriously underestimated its impact on sea ice. Results suggest places to improve forecast models in a changing Arctic Ocean.
Ed deHaan, associate professor of accounting in the University of Washington Foster School of Business, studies the impact of Buy Now Pay Later on financial health. His research finds that BNPL users faced rapid increases in bank overdraft charges and credit card interests and fees.
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.
University of Washington researchers examined 44 3D tours in 44 states across the U.S. to look for potential security issues when personal details were included in the tour.
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.
Adopting permanent DST 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 in the evening
The deep sea contains more than 90% of the water in our oceans, but only about a third of all fish species. Scientists have long thought the explanation for this was intuitive — shallow ocean waters are warm and full of resources, making them a prime location for new species to evolve and thrive. But 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.
A team led by researchers at the University of Washington has created a new hearing screening system that uses a smartphone and earbuds.
Michael Johnson, professor of management in the University of Washington Foster School of Business, found in a new study that groups that used “multivoting” in unofficial votes were 50% more likely to identify the correct option than those that used plurality or ranked-choice voting.
A team led by researchers at the University of Washington compared three potential strategies for reducing fine particulate matter pollution disparities across the contiguous U.S.
New research from the University of Washington professor Robert Palmatier examines how factors related to social media influencers, their posts and their followers impact marketing success. The study concluded that reallocating spending based on the study’s insights could result in a 16.6% increase in engagement.
Researchers at the University of Washington developed UnlockedMaps, a web-based map that allows users to see in real time how accessible rail transit stations are in six metro areas: Philadelphia, Chicago, Seattle, Toronto, New York and the California Bay Area. UnlockedMaps shows which stations are accessible and which ones are experiencing elevator outages.
