A new study led by the University of Washington finds the annual migration of some beluga whales in Alaska is altered by sea ice changes in the Arctic, while other belugas do not appear to be affected.
Eelgrass, a marine plant crucial to the success of migrating juvenile salmon and spawning Pacific herring, is stable and flourishing in Puget Sound, despite a doubling of the region’s human population and significant shoreline development over the past several decades.
New research finds that for some songbirds, urban sprawl is kicking them out of their territory, forcing divorce and stunting their ability to find new mates and reproduce successfully, even after relocating.
A new multi-institution study led by the UW shows more clearly than ever that urbanization is affecting the genetic makeup of species that are crucial to ecosystem health and success.
Joe Janes’ latest Documents that Changed the World podcast is about Sir Ronald Fisher, the man who set the mark of “statistical significance” for ages afterward at 5 percent, no more no less.
Most conscientious adults tend to avoid making biased or discriminatory comments in the presence of children. But new research from the University of Washington suggests that preschool-aged children can learn bias even through nonverbal signals displayed by adults, such as a condescending tone of voice or a disapproving look. Published Dec. 21 in the journal Psychological Science, the research found that children can “catch” social bias by seeing negative signals expressed by adults and are likely to generalize that learned…
In an article published Dec. 20 in the journal eLife, researchers present a mathematical model that explores whether “publication bias” — the tendency of journals to publish mostly positive experimental results — influences how scientists canonize facts. Their results offer a warning that sharing positive results comes with the risk that a false claim could be canonized as fact. But their findings also offer hope by suggesting that simple changes to publication practices can minimize the risk of false canonization.
Miqin Zhang, a professor of materials science and engineering at the University of Washington, is looking for ways to help the body heal itself when injury, disease or surgery cause large-scale damage to one type of tissue in particular: skeletal muscle. Her goal is to create a synthetic, porous, biologically compatible “scaffold” that mimics the normal extracellular environment of skeletal muscle — onto which human cells could migrate and grow new replacement fibers.
Research published this week in the Proceedings of the National Academy of Sciences suggests that successful fisheries management can be best achieved by implementing and enforcing science-based catch or effort limits.
Researchers from the University of Washington have found that scientific papers written in a more narrative style were more influential among peer-reviewed studies in the climate change literature. Their results were published Dec. 15 in the journal PLOS ONE.
The cracking, bulging and shaking from the eruption of a mile-high volcano where two tectonic plates separate has been captured in more detail than ever before. A University of Washington study published this week shows how the volcano behaved during its spring 2015 eruption, revealing new clues about the behavior of volcanoes where two ocean plates are moving apart. “The new network allowed us to see in incredible detail where the faults are, and which were active during the eruption,”…
On Dec. 10 in Stockholm, David James Thouless, University of Washington professor emeritus of physics, received the Nobel Prize in Physics from King Carl XVI Gustaf of Sweden.
The furor over the 2010 Citizens United decision drew intense scrutiny to the role of corporate money in U.S. politics and raised questions about the influence of businesses in American lawmaking. But corporate interests also play a powerful role in international legal processes, sometimes by covertly creating or co-opting non-governmental organizations to lobby lawmakers on their behalf — creating a type of “astroturf activism” that masquerades as grassroots efforts. That’s the conclusion of a new paper by Melissa Durkee, an…
In a paper published online Dec. 7 in the Proceedings of the National Academy of Sciences, University of Washington researchers report on a statistical approach called “tree bootstrapping” can help social scientists study hard-to-reach populations like drug users.
A University of Washington study addresses controversies over the cause of mountain glacier retreat, and finds that for most glaciers the observed retreat is more than 99 percent likely due to climate change.
A new study by paleontologists at the Burke Museum of Natural History & Culture and the University of Washington describes an early marsupial relative called Didelphodon vorax that lived alongside dinosaurs and had, pound-for-pound, the strongest bite force of any mammal ever recorded.
Answers to frequently asked questions about a 255-year-old tumor in a ‘pre-mammal.’
University of Washington paleontologists have discovered a benign tumor made up of miniature, tooth-like structures embedded in the jaw of an extinct ‘mammal-like’ gorgonopsian. Known as a compound odontoma, this type of tumor is common to mammals today. But this animal lived 255 million years ago, before mammals even existed.
People must be part of the equation in conservation projects to increase local support and effectiveness, according to a new study by the University of Washington and other institutions.
The U.S. Department of Transportation has awarded approximately $14 million over five years to a multi-university, regional transportation center led by the University of Washington to fund research aimed at improving the mobility of people and goods across the Pacific Northwest.
UW researchers have published the first demonstration of humans playing a simple, two-dimensional computer game using only input from direct brain stimulation — without relying on any usual sensory cues from sight, hearing or touch.
Water conducts electricity, but the process by which this familiar fluid passes along positive charges has puzzled scientists for decades. But in a paper published in the Dec. 2 in issue of the journal Science, an international team of researchers has finally caught water in the act — showing how water molecules pass along excess charges and, in the process, conduct electricity.
MusicNet is the first publicly available large-scale classical music dataset designed to allow machine learning algorithms to tackle everything from automated music transcription to listening recommendations based on the structure of music itself.
In a paper published Sept. 27 in the journal Small, scientists at the University of Washington describe a new system to encase chemotherapy drugs within tiny, synthetic “nanocarrier” packages, which could be injected into patients and disassembled at the tumor site to release their toxic cargo.
A new study of one of our closest invertebrate relatives, the acorn worm, reveals that regenerating body parts might one day be possible.
UW engineers have developed the first transgenic grass species that can take up and destroy RDX — a toxic compound that has been widely used in explosives since World War II and contaminates military bases, battlegrounds and some drinking water wells.

James Cook’s intricate 1778 records reveal global warming today in Arctic” Seattle Times, Nov. 16 Harry Stern, a polar scientist at the University of Washington’s Applied Physics Laboratory, has been studying the Arctic Ocean for decades, and sailed part of the Northwest Passage in 2009. Stern’s latest work uses the earliest explorers’ experiences to better understand a maritime environment that still contains many unknowns. A paper published in November in Polar Geography uses Captain James Cook’s…
Major forest die-offs due to drought, heat and beetle infestations or deforestation could have consequences far beyond the local landscape. Wiping out an entire forest can have significant effects on global climate patterns and alter vegetation on the other side of the world.
Children’s knowledge and use of race and gender labels have been well-explored by researchers, but how kids think about their own identities in those contexts, especially before adolescence, is less clear. A new study from the University of Washington provides a rare glimpse into how children perceive their social identities in middle childhood. The research found that children age 7 to 12 rate gender as more important than race — and that their perceptions of both are woven together with…
Research shows that real-time lightning observations could significantly improve forecasts of large storm events.
More than 90 percent of ivory in large, seized shipments came from elephants that died less than three years before, according to a new study from a team of scientists at the University of Utah, the University of Washington and partner institutions. They combined a new approach to radiocarbon dating of ivory samples with genetic analysis tools developed by UW biology professor Sam Wasser.
Alcohol abuse is pervasive in the military, where a culture of heavy drinking and the stress of deployment lead many soldiers down a troubled path. Almost half of active-duty military members in the United States — 47 percent — were binge-drinkers in 2008, up from 35 percent a decade earlier. Rates of heavy drinking also rose during that period, according to a 2012 report by the Institute of Medicine. But many in the military avoid seeking help for alcohol abuse,…
A University of Washington study is the first to broadly examine the ecological and financial impacts of seafood mislabeling. The paper, published online Nov. 2 in Conservation Letters, finds that in most cases, mislabeling actually leads people to eat more sustainably, because the substituted fish is often more plentiful and of a better conservation status than the fish on the label.
