Colony surveys of common murres, an Alaskan seabird, show the full effects of the 2014-16 marine heat wave known as “the blob.” Analysis of 13 colonies surveyed between 2008 and 2022 finds that colony size in the Gulf of Alaska dropped by half after the marine heat wave. In colonies along the eastern Bering Sea, west of the peninsula, the decline was even steeper, at 75% loss. No recovery has yet been seen.

University of Washington researchers show that the all-time record low in winter sea ice extent in 2023 can be explained by warm Southern Ocean conditions and patterns in the winds that circled Antarctica months earlier, allowing forecasts for sea ice coverage around the South Pole to be generated six or more months in advance. This could support regional and global weather and climate models.

NASA has awarded a five-year, $2.5 million grant to establish a regional scientific consortium based at the University of Washington, in partnership with Washington State University and the Pacific Northwest National Laboratory. The consortium will use an interdisciplinary approach to explore how the space environment — both in low-Earth orbit and beyond — affects living things.

Chelsea Wood, a University of Washington associate professor of aquatic and fishery sciences, has an upcoming children’s book titled “Power to the Parasites! Everything You (N)ever Wanted to Know About the Creepy Crawlies Hidden in Your Home, Your Food, Your Pets – and Maybe Even in You!” The book introduces kids to the world of parasitism.

Scientists have discovered the cuisine preferences of two resident killer whale populations, also known as orcas: the Alaska residents and the southern residents, which reside primarily in the Salish Sea and off the coast of Washington, British Columbia, Oregon and northern California. The two populations show broad preference for salmon, particularly Chinook, chum and coho. But they differ in when they switch to hunting and eating different salmon species, as well as the other fish species they pursue to supplement their diets. This information could aid conservation efforts for southern resident killer whales, which remain critically endangered due to pollution, loss of salmon habitat and other human-caused factors that disrupt their hunting and reproductive capabilities.

Some of the most dramatic climatic events in our planet’s history are “Snowball Earth” events that happened hundreds of millions of years ago, when almost the entire planet was encased in ice up to 0.6 miles thick. New research from the University of Washington provides a more complete picture for how the last Snowball Earth event ended, and suggests why it preceded a dramatic expansion of life on Earth, including the emergence of the first animals.

The University of Washington, the Affiliated Tribes of Northwest Indians and others held collaborative listening sessions with Northwest coastal Tribes to hear their experiences in adapting to climate change. A new report summarizes those experiences, while an upcoming grant program hopes to help address barriers identified in the report.

Fifteen faculty members at the University of Washington have been elected to the Washington State Academy of Sciences for 2024. They are among 36 scientists and educators from across the state announced Aug. 1 as new members. Selection recognizes the new members’ “outstanding record of scientific and technical achievement, and their willingness to work on behalf of the academy to bring the best available science to bear on issues within the state of Washington.”

Wolves returned to Washington state in 2008. A new study shows that, despite their rising numbers, wolves are not having much of an impact on white-tailed deer, one of their primary prey. In a paper published June 18 in Ecological Applications, scientists from the University of Washington and the Washington Department of Fish & Wildlife report that the biggest factor shaping white-tailed deer populations in northeast Washington is the quality of habitat available, which is largely determined by human activity. Cougars were second in their impact. Wolves were a distant third.

Research led by the University of Washington used computer models to pinpoint varieties of corn that will be best adapted to produce high yields in future U.S. climates. The study combined weather and climate projections across the U.S. for 2050 and 2100 with a plant model that simulates corn’s growth to find the mix of traits that will produce the highest, most reliable yield under future conditions across the country.

A UW atmospheric scientist will participate in a campaign to study winter storms and snowfall in northwestern Colorado’s Rocky Mountains. Like Seattle, this area depends on winter snow for its summer water supplies, so improving mountain snow forecasts will improve projections for summer drought and wildfire risks.

Spending time in nature is good for us. And knowing more about nature’s effects on our bodies could not only help our well-being, but could also improve how we care for land, preserve ecosystems and design cities, homes and parks. Many studies have focused on how seeing nature affects us. A team of scientists from around the world wants to understand what the nose knows. They are calling for more research into how odors and scents from natural settings impact our health and well-being.

A project led by the University of Washington to better understand our atmosphere’s complexity is a finalist for NASA’s next generation of Earth-observing satellites. STRIVE will receive $5 million to conduct a one-year concept study, and then will hear whether it is selected for launch.

As often as four days a week, Boeing EA-18G Growler electronic attack aircraft based at Naval Air Station Whidbey Island fly loops overhead as pilots practice touch-and-go landings. The noise is immense. New research from the University of Washington shows that the noise isn’t just disruptive — it presents a substantial risk to public health.

The University of Washington 149th Commencement is scheduled for Saturday, June 8, at Alaska Airlines Field at Husky Stadium. This year, the UW will recognize best-selling author Daniel James Brown and Susan Solomon, a professor of environmental science and chemistry at the Massachusetts Institute of Technology. Both will receive honorary degrees for their contributions to the humanities and sciences.

A detailed reconstruction of climate during the most recent ice age, when a large swath of North America was covered in ice, provides information on the relationship between CO2 and global temperature. Results show that while most future warming estimates remain unchanged, the absolute worst-case scenario is unlikely.

Forests could also be potential bulwarks against climate change. But, increasingly severe droughts and wildfires, invasive species, and large insect outbreaks — all intensified by climate change — are straining many national forests and surrounding lands. A report by a team of 40 experts outlines a new approach to forest stewardship that “braids together” Indigenous knowledge and Western science to conserve and restore more resilient forestlands. Published March 25, the report provides foundational material to inform future work on climate-smart adaptive management practices for USDA Forest Service land managers.

University of Washington researchers have shown that levels of anisakid worms — a common marine parasite — rose in two salmon species in the Gulf of Alaska and Bristol Bay over a 42-year period. The team discovered this by studying salmon caught, killed and canned from 1979 to 2021. Since anisakid worms have a complex life cycle involving multiple types of hosts, the researchers interpret their rising numbers as a potential sign of ecosystem recovery, possibly driven by rising numbers of marine mammals thanks to the 1972 Marine Mammal Protection Act.

Could life be found in frozen sea spray emitted from moons orbiting Saturn or Jupiter? New research finds that life can be detected in a single ice grain containing one bacterial cell or portions of a cell. The results suggest that if life similar to that on Earth exists on these planetary bodies, this life should be detectable by instruments launching in the fall.

An AI-powered analysis of 25 years of satellite images yields the surprising finding that methane emissions in Turkmenistan, a former Soviet republic and major oil-producing region, actually increased in the years following the dissolution of the Soviet Union.

Natural history museums have entered a new stage of discovery and accessibility — one where scientists around the globe and curious folks at home can access valuable museum specimens to study, learn or just be amazed. This new era follows the completion of openVertebrate, or oVert, a five-year collaborative project among 18 institutions to create 3D reconstructions of vertebrate specimens and make them freely available online. The team behind this endeavor, which includes scientists at the University of Washington and its Burke Museum of Natural History & Culture, published a summary of the project March 6 in the journal BioScience, offering a glimpse of how the data can be used to ask new questions and spur the development of innovative technology.

New research documents the fastest-known large-scale breakage along an Antarctic ice shelf. In 2012, a 6.5-mile crack formed in about 5 and a half minutes, showing that ice shelves can effectively shatter, though the speed of breakage is reduced by seawater rushing in. These results can help improve ice-sheet models and projections for future sea level rise.

Scientists at the University of Washington have discovered that nighttime air pollution — coming primarily from car exhaust and power plant emissions — is responsible for a major drop in nighttime pollinator activity. Nitrate radicals (NO3) in the air degrade the scent chemicals released by a common wildflower, drastically reducing the scent-based cues that its chief pollinators rely on to locate the flower. The findings, published Feb. 9 in Science, are the first to show how nighttime pollution creates a chain of chemical reactions that degrades scent cues, leaving flowers undetectable by smell. The researchers also determined that pollution likely has worldwide impacts on pollination.

Three new faculty books from the University of Washington cover wide-ranging topics: life in the Rio Grande Valley, fossils of Washington state and the colonial roots of contemporary intersex medicine. UW News talked with the authors to learn more. Collection highlights life in Rio Grande Valley “Puro Pinche True Fictions” is a collection of short stories and comics from José Alaniz, professor of Slavic languages and literature at the UW. The works are mostly set in the Rio Grande Valley…
