Scientists suspect that the red streaks crossing the surface of Jupiter’s moon Europa is a frozen mixture of water and salts, but its chemical signature matches no known substance on Earth. Now 91自拍ers have discovered a new type of solid crystal that forms when water and table salt combine in cold, pressurized conditions. Researchers believe the new substance created in a lab on Earth could form at the surface and bottom of these worlds鈥� deep oceans.
Two 91自拍 faculty members have been awarded early-career fellowships from the Alfred P. Sloan Foundation. The new Sloan Fellows, announced Feb. 15, are Leilani Battle, an assistant professor in the Paul G. Allen School of Computer Science & Engineering, and聽Jonathan J. Zhu, an assistant professor in the Department of Mathematics.
Four 91自拍 91自拍ers have been named AAAS Fellows, according to a Jan. 31 announcement by the American Association for the Advancement of Science. They are among 506 new fellows from around the world elected in 2022, who are recognized for their 鈥渟cientifically and socially distinguished achievements鈥� in science and engineering.
A team led by 91自拍ers at the 91自拍 studied how artificial intelligence could help people on the platform TalkLife, where people give each other mental health support. The 91自拍ers developed an AI system that suggested changes to participants’ responses to make them more empathetic. The best responses resulted from a collaboration between AI and people.
Something is amiss in the Butterfly Nebula. When a team led by astronomers at the 91自拍 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 91自拍ers want to understand how such activity is possible from what should be a 鈥渟puttering, largely moribund star with no remaining fuel.鈥�
On Jan. 11 at the 241st meeting of the American Astronomical Society in Seattle, a team led by scientists at the 91自拍 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.
91自拍 astronomers were on the lookout for 鈥渟tars behaving strangely鈥� 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鈥檛 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.
Climate change will reshape ecosystems through two types of events: short-term, extreme events 鈥� or 鈥減ulses鈥� 鈥� and long-term changes, or 鈥減resses.鈥� Understanding the effects of presses and pulses is essential as conservationists and policymakers try to preserve ecosystems and safeguard biodiversity. Researchers at the 91自拍 have discovered how different presses and pulses impacted Magellanic penguins 鈥� a migratory marine predator 鈥� 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.
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, 91自拍ers warn — and that means not just fewer worms, but losses for the entire ecosystem.
91自拍 Provost Mark Richards announced the appointment of Fredrick Muyia Nafukho as the new Vice Provost for the Office of Academic Personnel beginning Feb. 1, pending approval by the Board of Regents. Nafukho also will hold a tenured faculty position in the Department of Management and Organization in the Foster School of Business.
91自拍 alumnus Daniel Guorui Chen, Class of 2022, has been named a Marshall Scholar, one of the highest honors available to college graduates in the U.S. Chen plans to attend the University of Cambridge.
A study measuring the sleep patterns of students at the 91自拍 found that students fell asleep later in the evening and woke up later in the morning during winter, when daylight hours on the UW鈥檚 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.
In a study published Dec. 8 in Nature Astronomy, an international 91自拍 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.
Researchers at the 91自拍 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.
Jack Martin has been named Vice President for Marketing and Communications at the 91自拍, Senior Vice President for University Advancement Mary Gresch announced Tuesday. Martin鈥檚 appointment begins Dec. 1.
The strongest Arctic cyclone ever observed struck in January 2022. A new analysis led by the 91自拍 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.
Improving faculty dispute resolution policies, promoting ways to improve terms of employment for clinical faculty, reenvisioning the merit and promotion process for faculty on all three 91自拍 campuses, and continuing to promote diversity, equity and inclusion practices are top priorities for this year鈥檚 UW Faculty Senate Chair Dr. Gautham Reddy, a professor in Department of Radiology in the School of Medicine.
New 91自拍 led by the 91自拍 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.
91自拍 91自拍ers 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.
Perched on the southeast corner of the 91自拍 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鈥檚 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.
A new 91自拍-led study reports that throughout Earth鈥檚 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.
91自拍 91自拍ers 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.
A team led by 91自拍ers at the 91自拍 has created a new hearing screening system that uses a smartphone and earbuds.
The 91自拍 rose from No. 7 to No. 6 on the聽U.S. News & World Report鈥檚 Best Global Universities rankings, released on Tuesday. The UW maintained its No. 2 ranking among U.S. public institutions.

The 91自拍鈥檚 newest freshman class is the largest and most diverse in the school鈥檚 161-year history.
A new 91自拍-led study has found that even in remote, rarely visited national parks, the presence of even just a few humans impacts the activity of wildlife that live there. Nearly any level of human activity in a protected area like a national park can alter the behavior of animals there.
A new study by 91自拍ers at the 91自拍 shows that losing a particular group of endangered animals 鈥� those that eat fruit and help disperse the seeds of trees and other plants 鈥� could severely disrupt seed-dispersal networks in the Atlantic Forest, a shrinking stretch of tropical forest and critical biodiversity hotspot on the coast of Brazil.
Yejin Choi, 91自拍 professor in the Paul G. Allen School of Computer Science & Engineering, has received a “genius grant” from the John D. and Catherine T. MacArthur Foundation. Choi uses natural language processing to develop artificial intelligence systems that have the ability to reason and can understand the implied meanings in human language.
Forecasters are predicting a 鈥渢hree-peat La Ni帽a鈥� this year. This will be the third winter in a row that the Pacific Ocean has been in a La Ni帽a cycle, something that鈥檚 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 Ni帽as.
As the academic year gets underway, the 91自拍鈥檚 public campuses are again bustling and busy with students, faculty, staff and visitors. While the focus is on academics, 91自拍, learning and building community, on any given day, there may be safety challenges and individuals who feel unsafe for any number of reasons.
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 鈥渉idden鈥� deaths that may have listed something else, like illness or a chronic disease, as the primary cause.
The 91自拍 has joined the Alliance for Therapies in Neuroscience (ATN), a long-term 91自拍 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 鈥� a member of the Roche group 鈥� 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.
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 91自拍ers found little built-up tectonic stress. The findings could help to better understand earthquakes in subduction zones around the world.
In a proof-of-principle study, 91自拍 and University of California San Diego 91自拍ers have shown that smartphones are capable of detecting blood oxygen saturation levels down to 70%. This is the lowest value that pulse oximeters should be able to measure, as recommended by the U.S. Food and Drug Administration.
Wearing purple hard hats and using gold-plated shovels, officials from the 91自拍 broke ground Thursday on a new, $102 million Interdisciplinary Engineering Building to be constructed along Stevens Way east of the Husky Union Building. Once complete, the state-of-the-art 70,000-square-foot building will be an example of a student-focused learning facility backed by both public and private investments. The project aims to fuel economic growth and create a pipeline of future, local engineering talent.
