University of Washington researchers show that wildfire is increasingly impacting lands managed under the Northwest Forest Plan, a seminal measure enacted in 1994 to preserve habitat for endangered species.

Rivers cover more than 4 million miles of the U.S., but protections for rivers are piecemeal, accounting for less than 20% of total river length and varying widely by region, shows a new study co-led by the University of Washington.

The American Geophysical Union honored five University of Washington faculty and researchers from the departments of Earth and space sciences and atmospheric and climate science this week for their valuable researcher contributions.

More than a decade ago, data from the Cassini mission to Saturn suggested that the planet’s largest moon, Titan, had a vast ocean of liquid water below its frozen surface. In a new study, UW researchers teamed up with NASA scientists to show that the interior is likely composed of slushy layers instead.

New research led by the University of Washington suggests that two different climate transitions millions of years ago fueled the diversification of carnivoran body plans.

In a new study, University of Washington researchers collected salmon DNA in air filters near a stream, showing that eDNA can move between air and water, a possibility scientists hadn’t accounted for that opens new avenues for monitoring aquatic species.

“The Memory of Darkness, Light and Ice” — a documentary film featuring Eric Steig, a UW professor of Earth and space sciences — tells the story of a U.S. military and research base established in Greenland during the Cold War, and how the samples collected there are driving modern climate science. The film is now available on YouTube, Apple TV and Amazon Prime.

The green hermit hummingbird, which lives primarily in mountain forests of Central and South America, fights to win a mate. New research found that these fights have shaped the species’ evolution, yielding significant differences in bill shape for male and female green hermits.

The Northeastern Pacific Ocean is becoming more acidic faster than other oceans as the water absorbs carbon dioxide from the atmosphere and natural processes feed carbon dioxide up from the deep. The rate of CO2 accumulation is outpacing atmospheric rises and driving acidity to new extremes.

A new University of Washington-led study shows that space dust sandwiched between layers of sediment tells scientists where and when ice covered the Arctic, and what happened to marine life when it disappeared.

New University of Washington-led research attributes accelerated warming to reduced cloud reflectivity. As efforts to improve air quality have reduced pollution, clouds became less mirror-like, letting more solar radiation reach Earth and revealing the true impact of greenhouse gases.

In mid-pregnancy, exposure to any smoke was associated with an elevated risk of preterm birth, with that risk peaking around the 21st week of gestation. In late pregnancy, elevated risk was most closely associated with exposure to high concentrations of wildfire PM2.5, above 10 micrograms per cubic meter.

In the wake of One Ocean Week Seattle, participating University of Washington researchers share highlights, connecting the week’s events to ongoing efforts to understand and protect marine ecosystems and coastal communities.

University of Washington researchers analyzed data collected in the decade following the Paris Agreement, an international treaty signed in 2015 to limit warming by cutting emissions. The treaty has helped nations reduce the amount of carbon released per dollar, but emissions are still too high due to global economic growth.

A new collaborative study led by scientists at the University of Washington and the University of Maryland Center for Environmental Science proposes that a tsunami struck the Caribbean island of Anegada between 1381 and 1391, carrying huge coral boulders inland and leaving behind a valuable record of geologic and climatic history.

The Royal Swedish Academy of Sciences on Oct. 8 awarded the Nobel Prize in Chemistry to Susumu Kitagawa, Richard Robson and Omar M. Yaghi “for the development of metal-organic frameworks,” or MOFs. Both Dianne Xiao, a UW associate professor of chemistry, and Douglas Reed, a UW assistant professor of chemistry, use MOFs in their research at the UW. UW News reached out to them to learn more about the significance of these structures and how researchers use them.

Targeted drug delivery is a powerful and promising area of medicine. Therapies that pinpoint precise areas of the body can reduce the medicine dosage and avoid potentially harmful “off target” effects. Researchers at the UW took a significant step toward that goal by designing proteins with autonomous decision-making capabilities. By adding smart tail structures to therapeutic proteins, the team demonstrated that the proteins could be “programmed” to act based on the presence of specific environmental cues.

The Royal Swedish Academy of Sciences on Tuesday awarded the 2025 Nobel Prize in Physics jointly to John Clarke, Michel H. Devoret and John M. Martinis, “for the discovery of macroscopic quantum mechanical tunneling and energy quantization in an electric circuit.” Clarke, a professor emeritus of physics at the University of California, Berkeley, collaborates with the Axion Dark Matter Experiment at the University of Washington.

The Nobel Assembly at the Karolinska Institute on Monday awarded the 2025 Nobel Prize in Physiology or Medicine jointly to Mary E. Brunkow — an alum of the University of Washington — along with Frederick J. Ramsdell and Shimon Sakaguchi “for groundbreaking discoveries concerning peripheral immune tolerance that prevents the immune system from harming the body.” Brunkow received her bachelor’s degree in molecular and cellular biology from the UW in 1983. UW News spoke with Martha Bosma, professor and chair…

A new analysis of data from the Cassini space probe has identified organic compounds within jets of water ice erupting from Saturn’s moon Enceladus. Some of the compounds, which likely originated in Enceladus’ subsurface ocean, have never before been identified on another world beyond Earth. The study, conducted in part by a UW researcher, contributes to mounting evidence that Enceladus could support life.

In a new study, a team of scientists determined the minimum natural habitat on agricultural land that will allow insect pollinators — including bumble bees, solitary bees, hoverflies and butterflies — to thrive. UW News reached out to co-author Berry Brosi, UW professor of biology, to learn more about these results and how habitat is important to two types of bees native to Washington.

Students schools that offered free meals to all students were less likely to have high blood pressure, suggesting that universal free meals might be a powerful tool for improving public health.

Bee experts wouldn’t have previously expected to find the likes of Osmia cyaneonitens, Dufourea dilatipes and Stelis heronae in Washington. But this year, while collecting pollinators in Chelan County to study how climate and wildfires affect native bee populations, Autumn Maust, a University of Washington research scientist of biology, discovered eight bee species never recorded in Washington.

University of Washington researchers found, in historical whaling data, that longer baleen whale mothers were more likely to birth female calves than males. These results run contrary to a leading evolutionary theory that suggests that fit mothers will benefit more from male offspring.

Quantum dots, which are 10,000 times smaller than the width of a human hair, are unique materials that generate very specific colors of light. Researchers, including Brandi Cossairt, UW professor of chemistry, hope that quantum dots can one day be useful for more than just illuminating TV screens. UW News asked her to compare the quantum dots in QLED TVs with the ones her lab makes.

The James Webb Space Telescope has revealed new details in the core of the Butterfly Nebula, known to astronomers as NGC 6302. From the dense ring of dust that surrounds the nebula’s core to the tiny but bright star hidden within, the Webb observations paint a never-before-seen portrait of the nebula’s inner workings. Researchers at the UW and around the world are studying the imagery to learn more about the origins of cosmic dust and its role in the formation of planets like ours.

Dengue fever incidence could rise as much as 76% by 2050 due to climate warming across a large swath of Asia and the Americas, according to a new study.

Antarctic ice is melting at a startling pace, and the West Antarctic Ice Sheet is one of the greatest sources of uncertainty in climate projections. Researchers thought westerly winds were accelerating ice loss, but a new study from UW flips the narrative by 90 degrees, pointing instead to winds from the north.

Prochlorococcus, the most abundant photosynthesizing organism in the ocean, might be more vulnerable to climate change than researchers thought. Population decline could weaken the foundation of subtropical and tropical ecosystems as ocean temperatures continue to rise.

New findings call into question one of the core assumptions about teeth. Adult male spotted ratfish, a shark-like species native to the eastern Pacific Ocean, have rows of teeth on top of their heads, lining a cartilaginous appendage called the tenaculum, in addition to those in their jaws. They used their tenaculum teeth to grip females while mating in water.

Physicists have floated numerous theories to explain what dark matter might be, but to date, no experiment has turned up compelling evidence to support any of them. An international team of physicists, including researchers from the UW, is now working on a new kind of dark matter detector with the goal of capturing the first direct observation of the puzzling material. Results from the detector’s prototype have already ruled out one of the leading theories of how dark matter originated.

New research shows that deep-ocean oxygenation occurred 100 million years later than previously thought, aligning with the growth and spread of land plants. Once oxygenated, the ocean hosted rapid animal evolution, leading to the rise of modern vertebrates.

University of Washington researchers use AI to simulate the Earth’s current climate and interannual variability for up to 1,000 years. The model runs on a single processor and takes just 12 hours to generate a forecast.

A UW-led team of researchers used a fiber-optic cable to capture calving dynamics across the fjord of the Eqalorutsit Kangilliit Sermiat glacier in South Greenland. This allowed them to document — without getting too close — one of the key processes that is accelerating the rate of glacial mass loss and in turn, threatening the stability of ice sheets, with consequences for global ocean currents and local ecosystems.

Antimicrobial resistance is a lurking threat in hospitals around the world. As more strains of bacteria and other microbes evolve defenses against available drugs, more patients run the risk of contracting infections that defy treatment. Now, University of Washington researchers offer new insights into measures currently used to control the spread of antibiotic resistant bacteria and other infectious agents in health care facilities.

An international team of paleontologists, led by researchers at the University of Washington and the Field Museum of Natural History, is identifying the animals that thrived in southern Pangea — the planet’s single supercontinent at the time — just before the so-called “Great Dying” wiped out about 70% of terrestrial species, and an even larger fraction of marine ones.

A UW-led project aimed to test the viability of seaweed as a soil amendment, and, if successful, develop a market for sea-based farmers to sell excess seaweed to their counterparts on land. The USDA froze the project’s funding, and for now, a solution remains just out of reach.

An international research effort, including scientists from the University of Washington, has finally revealed the cause of sea star wasting disease: a strain of the bacterium Vibrio pectenicida.
