On Feb. 7, 2021, a wall of debris and water barreled down river valleys in India, destroyed two hydropower facilities and left more than 200 people dead or missing. A self-organized coalition of 53 scientists from 14 countries, including researchers from the University of Washington, worked nonstop following the disaster to investigate the cause, scope and impacts.

University of Washington glaciologists are co-authors on two papers that analyzed Antarctic ice cores to understand the continent’s air temperatures during the most recent glacial period. The results help understand how the region behaves during a major climate transition.

Many seabirds in the Northern Hemisphere are struggling to breed — and in the Southern Hemisphere, they may not be far behind. These are the conclusions of a study, published May 28 in Science, analyzing more than 50 years of breeding records for 67 seabird species worldwide.

Researchers at the University of Washington and its Burke Museum of Natural History & Culture have discovered the first fossil evidence of an ancient amphibian, Micropholis stowi, from Antarctica. Micropholis lived in the Early Triassic, shortly after Earth’s largest mass extinction. It was previously known only from fossils in South Africa, and its presence in Antarctica has implications for how amphibians adapted to high-latitude regions in this dynamic period of Earth’s history.

Ice core data from Greenland shows why air pollution is dropping more slowly than sulfur emissions reductions. As cloud droplets become less acidic, the chemical reaction that turns sulfur dioxide into sulfate aerosol gets more efficient. The new results can improve the models that project air quality and climate change.

The newest experiment at CERN, the European Organization for Nuclear Research, is now in place at the Large Hadron Collider in Geneva. FASER, or Forward Search Experiment, was approved by CERN’s research board in March 2019. Now installed in the LHC tunnel, this experiment, which seeks to understand particles that scientists believe may interact with dark matter, is now undergoing tests before data collection commences next year.

The U.S. Geological Survey, the University of Washington-based Pacific Northwest Seismic Network, and state emergency managers on Tuesday, May 4, will activate the system that sends earthquake early warnings throughout Washington state. This completes the rollout of ShakeAlert, an automated system that gives people living in Washington, Oregon and California advance warning of incoming earthquakes.

Five faculty members and one affiliate professor at the University of Washington are among 120 new members and 30 international members elected to the National Academy of Sciences: Anna Karlin, professor of computer science and engineering; Rachel Klevit, professor of biochemistry; Randall LeVeque, professor emeritus of applied mathematics; Julie Theriot, professor of biology; Rachel Wong, professor of biological structure; and Julie Overbaugh, professor at the Fred Hutchinson Cancer Research Center and a UW affiliate professor of microbiology.

When people think of misinformation, they often focus on popular and social media. But in a paper published April 12 in the Proceedings of the National Academy of Science, University of Washington faculty members Jevin West and Carl Bergstrom write that scientific communication — both scientific papers and news articles written about papers — also has the potential to spread misinformation.

The first results from the Muon g-2 experiment hosted at Fermi National Accelerator Laboratory show fundamental particles called muons behaving in a way not predicted by the Standard Model of particle physics. These results confirm an earlier experiment of the same name performed at Brookhaven National Laboratory. Combined, the two results show strong evidence that our best theoretical model of the subatomic world is incomplete. One potential explanation would be the existence of undiscovered particles or forces.

Lightning strikes in the Arctic tripled from 2010 to 2020, a finding University of Washington researchers attribute to rising temperatures due to human-caused climate change. The results, researchers say, suggest Arctic residents in northern Russia, Canada, Europe and Alaska need to prepare for the danger of more frequent lightning strikes.

Thanks to 20 years of observations from thousands of citizen scientists, University of Washington researchers have discovered distinct patterns in the mass strandings of by-the-wind sailor jellies. Specifically, large strandings happened simultaneously from the northwest tip of Washington south to the Mendocino coast in California, and in years when winters were warmer than usual.

The future of an equitable and sustainable global ocean, or “Blue Economy,” depends on more than natural or technological resources. A new study finds that socioeconomic and governance conditions such as national stability, corruption and human rights greatly affect different regions’ ability to achieve a Blue Economy — one that is socially equitable, environmentally sustainable and economically viable.

In a study published Feb. 15 in Nature Chemistry, a research team led by Munira Khalil, professor and chair of chemistry at the University of Washington, has captured the rapid motions of solvent molecules that impact light-driven electron transfer in a molecular complex for the first time. This  information could help researchers learn how to control energy flow in molecules, potentially leading to more efficient clean energy sources.

Writing in the New England Journal of Medicine that they “do not believe that ignoring race will reduce health disparities” but rather that “such an approach is a form of naive ‘color blindness’ that is more likely to perpetuate and potentially exacerbate disparities,” five Black geneticists set out to explain the pitfalls of leaving race out of medicine. Importantly, the geneticists explain, while it is imperative to be considered now in many settings, race is an imperfect stepping stone toward…

The Arctic Ocean’s Beaufort Sea has increased its freshwater content by 40% over the past two decades. When conditions change this freshwater will travel to the Labrador Sea off Canada, rather than through the wider marine passageways that connect to seas in Northern Europe. This has implications for local marine environments and global ocean circulation.

To understand how Puget Sound has changed, we first must understand how it used to be. But unlike most major estuaries in the U.S., long-term monitoring of Puget Sound fish populations did not exist until 1990. Now researchers have discovered an unconventional method to help fill in gaps in the data: old vessel logbooks.

Even if all countries meet their Paris Agreement goals for reducing emissions, Earth has only a 5% chance of staying below 2 C warming this century, a previous study showed. But reductions about 80% more ambitious, or an average of 1.8% drop in emissions per year rather than 1% per year, would be enough to meet the Paris Agreement’s temperature goal.

Morales has authored a seven-part series for Ars Technica on quantum mechanics for a general audience. One article in the series is rolling out each week from Jan. 10 to Feb. 21. Morales sat down with UW News to talk about the series, quantum mechanics and what he hopes the public can learn about this seemingly odd and possibly intimidating realm of science.

Human-caused warming is responsible for increasing the risk of a glacial outburst flood from Peru’s Lake Palcacocha, threatening the city below. This study is the first to directly link climate change with the risk of flooding from glacial lakes, which are growing in number and size worldwide.

Single-celled organisms in the open ocean use a diverse array of genetic tools to detect sunlight, even in tiny amounts, and respond. The discovery of these new genetic “light switches” could also aid in the field of optogenetics, in which a cell’s function can be controlled with light exposure.

A new University of Washington paper quantifies the tradeoffs between hydroelectric generation capacity and the impacts on river connectivity for thousands of current and projected future dams across Brazil. The findings confirm that small hydropower plants are far more responsible for river fragmentation than their larger counterparts due to their prevalence and distribution.

Sleep cycles in people oscillate during the 29.5-day lunar cycle: In the days leading up to a full moon, people go to sleep later in the evening and sleep for shorter periods of time. The team, led by researchers at the University of Washington, observed these variations in both the time of sleep onset and the duration of sleep in urban and rural settings — from Indigenous communities in northern Argentina to college students in Seattle, a city of more than 750,000. They saw the oscillations regardless of an individual’s access to electricity, though the variations are less pronounced in individuals living in urban environments.

A University of Washington-led team has revisited and comprehensively reinterpreted the radio telescope observations underlying a widely reported 2019 claim that phosphine gas was present in the atmosphere of Venus. In a paper accepted to the Astrophysical Journal, they report that sulfur dioxide, a common gas in the atmosphere of Venus, is likely what was detected instead of phosphine.

A study accepted by the Planetary Science Journal shows that the planets of the TRAPPIST-1 system share similar densities. That could mean they all contain roughly the same ratio of materials thought to be common to rocky planets, such as iron, oxygen, magnesium and silicon — though they appear to differ notably from Earth.
