Fish that split their lives between fresh and salt water often face obstacles getting back and forth. Dams and roads fracture river networks and interfere with traditional migratory routes, sparking concerns about fish health and abundance, as well as biodiversity on a broader scale.

Efforts to restore fish passage are cropping up across the country, but these projects come with hefty price tags. In a new study, , ����ԭ�� researchers explore whether this money is being well spent by examining the process that determines which projects are prioritized.

The current standard, called score and rank, involves evaluating barriers one by one and assigning a score based on potential gains, such as habitat expansion. Top-ranking projects become leading candidates for funding, but score and rank systems don’t always account for barriers in the full river context. High-scoring projects can yield stranded investments, where removing the barrier doesn’t have the desired outcome because of other barriers downstream or immediately upstream.

“Ideally, barriers that are most downstream will score higher, because they need to come out before the fish can benefit from upstream restoration, but approaches to scoring vary, so this isn’t always the outcome,” said lead author , a UW associate professor of marine and environmental affairs.

As an alternative to score and rank, this study presents a mathematical computer program called optimization. Optimization synthesizes many inputs to make the most of a budget. It can serve as a performance indicator for other systems and highlight opportunities for improving an underperforming system.

“It’s looking at a portfolio instead of going barrier by barrier. In doing so, you can explicitly account for watershed connectivity and evaluate the performance of score and rank,” Jardine said.

As concerns about the health of rivers mounted in recent years, state and federal governments have allocated billions of dollars toward reconnecting them. Fragmentation is an established threat to biodiversity, and recent studies show that a vast majority of river length is not protected by conservation measures.

Washington state is in the midst of a court ordered multibillion dollar effort to remove barriers that block salmon and steelhead from swimming upstream to spawn. The combines score and rank with optimization in a hybrid approach. Similar projects elsewhere tend to use score and rank.

“I think people see optimization as a black box because it’s not as obvious why a barrier rose to the top of the priority list,” Jardine said. “With score and rank, they understand the scores and the process, but we don’t really know what the outcome will be.”

In this study, researchers use fish passage in Western Washington as a case study to compare score and rank to optimization. They show that score and rank performs decently well when the only goal is opening up as much habitat as possible, but adding other variables into the mix, such as habitat quality, compromises its performance.

While optimization has the capability to balance variables, it might not work for everyone. The program needs data to run and someone with a mathematical background to run it. Still, even small tweaks to the score and rank approach can produce results that rival optimization.

“Major change is hard, but minor changes may be enough,” Jardine said.

Because these projects often represent the values of multiple stakeholders, it’s important to include safeguards against stranded investments.

“You need to work from downstream up to make sure the success of a project isn’t contingent upon other projects,” Jardine said. “We’re spending a lot of money on this, but the total cost of restoring all barriers is much higher than the budget, so it’s really important that we make the most out of the financial resources that we have.”

Is it a doctor’s job to get the best outcomes for their patients or to tell the truth? What happens when these two things are not aligned? These are questions that ����ԭ�� students have to wrangle with in Biol 180: Introductory Biology. The goal, says , UW assistant professor of biology, is to have students experience a more nuanced side of biology. There is not always one right answer, and issues of power and relationships often come into play.

Theobald aims to connect the biology concepts the students learn in class to real-world issues, something she hopes will help both retain students in the biology major at the UW and help non-majors in the class with their future careers.

Just how common is it for biology curricula to include real-world examples? One way to answer this question is to look at educational resources for biology instructors.

In published in Disciplinary and Interdisciplinary Science Education Research, Theobald and her team examined almost 3,000 science guidelines and assessment questions from 16 sources — including MCAT practice questions and questions from the Washington Comprehensive Assessment of Science and AP biology tests — for any connections to society. Of the approximately 200 elements — about 7% — that had real-world implications, many discussed ethics and public health issues.

UW News spoke with Theobald; lead author , UW postdoctoral fellow in biology; and co-author , UW doctoral student in biology, to find out more about these results and what they mean for biology education today.

Why do you think so few learning objectives and assessment questions were connected to real-world examples?

Carly Busch: One reason is probably that there’s a perception that real-world connections are not a part of the primary purpose of the course, that they only belong as an addendum or an aside.

This perception makes sense in some ways, given how departments and institutions have conceptualized biology and what biology undergraduate students expect to get out of a biology degree. But the lack of these connections to society was also remarkable, because I think they play a really important role in developing undergraduate students holistically and broadly as they continue on in their science careers. Real-world examples can support students’ interest in science and help them develop their scientific identity.

Madison Meuler: I think there is also a belief of, “Oh well, this is an intro biology class. If this person is going to be a scientist, they’ll get training in the societal stuff later.” But I think there’s value in having this type of information even in intro courses.

Students in these courses may or may not go on to major in biology, and may or may not pursue a career in STEM. But even if this is their only science course in college, what could they take away from it that can help them be an informed citizen in the world?

Science plays a huge role in politics and in a lot of decisions that affect people’s day-to-day lives. It’s a missed opportunity if you’re not making those connections in the classroom. We want students, regardless of their future careers, to at least walk away being equipped with some skills to critically analyze the role that science is playing in society.

You found that roughly half of the questions that did mention society only vaguely referenced real-world scenarios. Can you give examples of implicit versus explicit mentions?

CB: So the most vague mention was from the American Association of Immunologists’ recommendations for an undergraduate immunology course. This is one of the advanced subtopics that they list: the implications of Emil Von Behring’s . We coded it as a vague mention because some of those implications could be related to society, not only focused on scientific experiments.

An example of explicit incorporation is from the bioinformatics core competencies. It asks students to explain the implications, good and bad, of being able to walk into a doctor’s office and have your genome sequenced and analyzed, or of being able to obtain genetic information from direct-to-consumer testing services. There we have a very clear example of students being asked to think about how the science concept fits in with society.

Do you think that connecting science to society can help retain students in science?

CB: We haven’t tested this yet, but based on prior research, there is reason to believe that incorporating these connections is going to help students be more engaged in what they’re learning in class. Engagement is closely tied to students’ performance outcomes, which often make or break their decision to persist in a major.

There is also a theory that helping students apply what they’re learning in the classroom to things happening in their lives and in their communities .

This is something I am excited to study in the future — to understand how making these connections expands students’ perceptions of what science is and who does science. The types of research questions that most scientists ask are on topics they personally are interested in. Maybe they study wildflowers in Washington because they love hiking, and they’ve always been struck by how beautiful the flowers are. That’s the beauty of being an academic researcher: You get to explore all of the different things that you’re curious about.

MM: Connecting content to real-world experiences could also increase retention by helping students feel a sense of belonging in the classroom. You’re far less likely to persist in a class if you feel like you don’t belong in that physical space, right? The course content definitely plays a role in that.

I think that making these connections between content and societal issues could help students start thinking things like, “Oh, this is a thing I care about, how could I design a study that could provide evidence to help inform a policy decision?”

Elli Theobald: Students have said to me, “I don’t want to be a scientist because I want to help people.” And that’s a problem. If we’re teaching science in a way that makes it feel like it isn’t helping people, then we’re doing something wrong. It’s just such a huge disservice to biology because we’ll lose so many amazing and capable students who could push our field forward.

This study looked at biology education resources. Do you know if biology instructors are already incorporating more real-world connections in their courses? ��

CB: If instructors aren’t getting support but they’re still making these connections in the classroom, it’s because they are putting that onus on themselves and choosing to add it. I applaud all instructors who are making these connections, and I fully expect that more connections are being made than and in these resources. We are currently collecting actual course materials from intro bio courses to see where instructors are making these connections.

But I also think that it would be such a valuable resource for instructors to have more support in making those connections. Here’s where I think really bolstering the amount of resources for instructors could provide more scaffolding for instructors to be able to provide a variety of connections, or to even recognize opportunities to make these connections in the course objectives. One of my hopes for this work is that it helps to provide motivation for those sorts of materials.

ET: Instructors are amazing. They’re working so hard to connect the content in some way to students’ lives, or to find the best, coolest examples. They need to have support from their institutions to be able to do more of this in their classrooms.

Plants may not appear aggressive, but they can still defend themselves while under attack. When caterpillars chomp the leaves of bean plants, these plants release gases that lure predatory wasps. The wasps prey on the caterpillars, saving the plants from further destruction. In a paper , a UW-led team demonstrated that this defense strategy is run by a protein called INR, or inceptin receptor. The researchers grew bean plants with naturally occurring mutations in the INR gene alongside plants with functional INR in an experimental field in Oaxaca, Mexico. The knock-out plants didn’t emit gases and attracted far fewer wasps. This result helps explain a previous study by this team that first identified the biochemical pathway behind this defense mechanism. These results also showcase how the tiny actions of a single protein can affect the behavior of wasps and caterpillars, and in turn, protect the health of the plant. This could benefit nearby plants as well, the researchers said. Beans are often grown alongside “,” such as corn, with the idea that each plant provides a benefit for the others. Beans help make the soil richer for their companions, and, through the actions of INR, could also protect their neighbors from pests.

Decades of satellite data show Himalayan rivers migrating rapidly in response to climate change

The movement of rivers is often described in terms of flowing water, but the path a river takes can also change. Some migration is normal, but in the Himalayas, rivers seem to be scrambling faster than scientists anticipated. In a study , researchers show that rivers in the Tibetan Plateau moved twice as much from 2000 to 2020 as they did from 1980 to 2000. As glaciers melt and frozen ground thaws in response to rising temperatures, rivers are inundated with silty meltwater from surrounding glaciers. The water picks the path of least resistance through softening ground. The “movement” includes small lateral shifts, big swings that cut off entire sections of river and occasionally, . The international team attributes their observations to climate change, which is driving temperatures up faster here than many other places. More than 2 billion people rely on these rivers for fresh water and researchers are concerned about communities downstream, as well as the potential for similar patterns that may play out elsewhere.

Researchers shrink eye-catching structure down to the nano scale��

made using a network of freestanding bars suspended by a web of thin, tense cables. The organization of the bars and cables allows the network of tension and compression forces to lock everything into place, creating a lightweight yet stiff structure. Tensegrities of different sizes are common in nature — examples include and the that help living cells maintain their shape — as well as in diverse manmade structures like , and . Now, a team of engineers at the UW have found a way to create tensegrities as small as five micrometers across — roughly a tenth of the width of a human hair. in the aptly-named journal Small, researchers used a specialized and a resin compound to print bar-and-cable structures about 30 micrometers across. They then heated the materials to 900 degrees celsius, causing the structures to shrink by over 80%. As they shrank, the thinner cables constricted more than the bars, resulting in nanostructures with specific, locked-in levels of stress that were up to 250% stiffer than the starting structures. The team is now working on ways to build larger materials composed of tiny tensegrities, which could eventually usher in a new class of stiff, light and impact-resistant materials.

Scientists find a key water source for atmospheric rivers

In December 2025, brought a seemingly endless onslaught of precipitation to Washington that caused and washed away roads and homes. In published in the Journal of Geophysical Research: Atmospheres, UW researchers help explain where all that water came from. They describe a link between the , a weather pattern that brings moisture east across the Pacific, and atmospheric rivers. Hypotheses about this connection have emerged from previous studies, but researchers couldn’t physically draw it until now. By tracking precipitation and wind patterns from 2000 to 2024, the UW researchers show that heavy rainfall and flooding are more likely when MJO is active, which happens several times a year. By identifying the MJO as a key moisture source for powerful atmospheric rivers, the researchers hope to improve forecast accuracy and give people more lead time to prepare for incoming storms.

Maeda also was appointed a professor of American ethnic studies. He succeeds Dianne Harris, who will complete her service this year.

Maeda has previously served as the dean of the University of Colorado Boulder College of Arts and Sciences where he also was a professor of ethnic studies. He is an interdisciplinary cultural historian and is a nationally recognized scholar in Asian American studies and comparative ethnic studies.

“Dr. Maeda brings a wealth of experience to all aspects of the role of Katherine and John Simpson Endowed Dean for the College of Arts & Sciences, including a deep commitment to shared governance,” Serio said. “Throughout the selection process, Dr. Maeda repeatedly elevated the broad strengths of the College of Arts & Sciences, and the students, staff and faculty who define them, as foundational to leading the path forward through a framework of opportunity for all.”

Since joining CU Boulder as an assistant professor in 2005, Maeda has served as chair of the Department of Ethnic Studies, associate dean for student success in the College of Arts and Sciences, and dean and vice provost of undergraduate education. Maeda served as interim dean of the College of Arts and Sciences since June 2024 until he was appointed dean earlier this year. He is returning to the UW where he was an acting assistant professor in the Department of History from 2001 to 2002.

“I am deeply honored to serve the College of Arts & Sciences and grateful for the opportunity to partner with its exceptional faculty, students and staff,” Maeda said. “Together, we will build on the college’s distinguished tradition of discovery, creativity and public impact while advancing an inclusive and inspiring vision for the future.”

The College of Arts and Sciences at CU Boulder has 1,300 faculty members and 400 staff members. The college also has approximately 15,000 undergraduates in 49 majors and more than 2,000 graduate students in 36 doctoral programs and 35 master’s programs. As dean, Maeda managed an annual budget of more than $250 million and led a collaborative process that created the college’s budget allocation model. Under his leadership, the college established new records for first-year retention and six-year graduation rates and set a record for highest annual fundraising in the college’s history.

Maeda has published two books and numerous articles and book chapters on Asian American activism in the 1960s and 1970s. His most recent book, a cultural history of the iconic martial artist and actor — and former UW student — Bruce Lee, was published in 2022.

Maeda earned his doctoral and master’s degrees in American culture from the University of Michigan. He also holds a master’s in ethnic studies from San Francisco State University and a bachelor’s in mathematics from Harvey Mudd College.

What happens to our understanding of relational memory when viewed through queer histories? In this talk, Stirner examines memory art dedicated to often neglected queer and trans histories after National Socialism, from translucent quilts to an installation that melts a concentration camp gate and rewelds it into new forms. Beyond arguing for the inclusion of queer histories in relational frameworks of remembrance, the talk proposes that attending to the distinct shapes and textures of queer relationality reshapes the concept itself, showing how queer memory practices expand and transform what it means to think memory relationally.

Simone Stirner (Assistant Professor, Germanic Languages & Literatures, Harvard University) works on poetry and poetics, memory studies, and the intersections of critical and creative practices. Stirner’s first book Poetic Grief: Form and Remembrance after National Socialism (Fordham University Press, forthcoming) develops a new framework for understanding the relationship between reading poetry and the affective experience of grief by studying how poems in the enduring aftermath of National Socialism and the Holocaust make space for an encounter with the uncontainable dimensions of loss—on and off the page.��Free.

Burrowing shrimp are small marine excavators native to Washington. They make their homes deep in the sediment by digging, turning the ground to Swiss cheese. This presents a problem for shellfish farmers, whose clams and oysters are often smothered under layers of displaced sediment.

Burrowing shrimp have been a nuisance for at least a century. In 1929, : “Oyster growers have tried various means of defense against these persistent burrowers. But there seems to be as yet no really adequate and at the same time practical method of coping with the marine ‘crayfish.'”

Shellfish farmers used to use pesticides to kill the shrimp, but the chemicals also posed risks to other organisms, such as salmon and crabs, and could be transported in water outside the shellfish growing area. The Department of Ecology in 2018. Since then, family-owned shellfish farms have been losing large portions of their growing grounds to burrowing shrimp.

Research led by the UW, and funded by the state, has yielded a non-chemical, proof-of-principle method for killing shrimp in targeted areas. The method, borrowing from the construction industry, uses a custom-built platform to apply vibration and pressure to a 50-square-foot region of sediment. This compacts the sediment and effectively traps shrimp in their burrows. Starved of oxygen, the shrimp die after a few days.

The researchers tested this method at four sites around Willapa Bay, Washington. It worked just as well as pesticides, reducing the number of live shrimp by between 72% and 98%.

“The challenge of managing burrowing shrimp on private tidelands has many dimensions. There still need to be enough shrimp to serve as food for gray whales and sturgeon, and the whole shrimp population is connected by a long larval phase in the ocean,” said senior author , UW professor of biology. “Once back in the estuary though, these shrimp can live for up to 10 years. Even a moderately sized shrimp, about four inches long, can bring a handful of sediment to the surface every day, dropping that on top of everything. We’re trying to find the balance — how to keep them out of shellfish beds, but let them grow elsewhere.”

The team May 12 in the Journal of Shellfish Research.

“Burrowing shrimp have decimated our farm,” said Ken Wiegardt, a fifth-generation oyster farmer and head of Jolly Roger Oysters in Willapa Bay. “We’ve lost 75% of our nursery ground and, as a result, the farm’s carrying capacity has fallen from 265,000 bushels of market-ready oysters to 75,000 bushels. Last month I had to lay off three oyster shuckers, each of whom had been with me for many years, because I just don’t have the oysters to process. The health of the Willapa Estuary as well as my business and all of my employees depend on finding an effective tool.”

Over the years farmers and researchers have toyed with the idea of trying to “mechanically” control shrimp populations.

“The idea was, ‘Let’s crush them underground, or crush them when they come to the surface,'” Ruesink said. “There are old photographs that show people using vehicles, such as repurposed tanks and snow crawlers, to try to target the shrimp.”

This idea resurfaced at a recent conference. Over lunch, Ruesink and shellfish growers decided . After careful analysis, the method proved ineffective.

Ruesink’s co-author, Alan Trimble, who was previously a research scientist at UW and is now volunteering on this project, had an idea for why the “crushing” experiment had failed.

“He told me, ‘You’re thinking like a dirt farmer and you need to start thinking like a concrete engineer instead,'” Ruesink said. “That’s when he mentioned these concrete vibrators in construction. When you pour concrete, if you don’t get all the bubbles out of it, it won’t be as strong. This is a consolidation technique for a wet slurry of particulates, which is exactly what a mud flat is.”

Ruesink and Trimble ran three experiments to test whether a concrete vibrator, a hand-held metal tube with a motor powered by a generator, could kill the shrimp. For each experiment the team compared sediment cores from treated plots to cores from untreated plots. The researchers took core samples on multiple days after treatment and counted live versus dead shrimp.

In an earlier experiment, the team tried using the vibrator while standing in the water. This method was successful in killing shrimp, but also not practical for scaling up. Jennifer Ruesink/����ԭ��

The best option was a custom-built floating platform with six vibrators mounted through a hollow part in the middle. Ruesink and Trimble added weights near each vibrator head to provide pressure in addition to vibration, a winning combination that compressed the sediment and killed the shrimp. The specific cause of death was asphyxiation, not the vibration.

While this proof-of-principle experiment seems promising, there’s more work to do before shellfish farmers can implement it. Right now it’s a time-consuming and labor-intensive process because everything is manually operated. Also, more studies need to be done to determine the long-term impacts to the ecosystem, from the shrimp in neighboring non-shellfish farm mudflats to other creatures living in the area.

“What we’ve done so far is introduce a novel control mechanism. No one had thought that you could trap the shrimp underground,” Ruesink said. “But this research wouldn’t have happened without the investment from the state and the private landowners and growers. I have such a deep appreciation for the opportunity to work with folks on something that is clearly affecting their lives.”

The researchers performed field trials on the private tidelands of Pacific Shellfish, Bay Center Farms and John Heckes. This research was funded by the Washington State Department of Agriculture.

���������첹’s was home to beluga whales in the late 1970s, but today the population hovers around 300. Despite almost two decades of recovery work, the whales aren’t bouncing back. The Cook Inlet belugas are likely struggling under multiple pressures, including increasing human noise. Researchers are working on deciphering whale-whale communication to better account for the impact of noise on this vulnerable population.

In a new study, ����ԭ�� scientists eavesdropped on Cook Inlet belugas, recording more than 1,700 calls representing 21 different behavioral encounters. This work builds on a 2023 study showing that noise from commercial shipping, the primary industry in the region, masks common beluga calls. Although many marine mammals rely more on sound than sight, our understanding of acoustic communication among these animals is limited.

Beluga whales use vocalizations to socialize, stick together and avoid danger. The new study, , investigated the behavioral, social and environmental contexts in which the whales produce various calls.

“We knew that human-generated noise was masking their calls, but we didn’t know what those calls were used for,” said, a UW doctoral student in aquatic and fishery sciences. “This study gave us important insights into the world of beluga communication and how it is disrupted by industry and development.”

They found that Cook Inlet belugas use a specific type of call — a combined call — when calves are present. Combined calls were one of the call types that got drowned out by shipping noise in the 2023 study, suggesting that shipping noise could be disrupting communication with calves. If mothers and calves can’t remain in contact, it could spell trouble for the young whales.

“We don’t have the data to directly connect noise and calf separation,” Brewer said, “but if a mother whale can’t acoustically keep in contact with her calf, that could be a huge problem.”.

Researchers also found that calling between whales increased right before a behavioral change in the group, such as a transition from socializing to traveling, and when the tide was coming in. The call rate for individual whales decreased as group size increased, suggesting that individuals call less in a big group, perhaps to avoid talking over each other.

In Cook Inlet, where the whales live year round, silty glacial water gets churned up by powerful currents and dramatic tides. Beluga whales likely moved in after the last ice age, roughly 10,000 years ago. Vocal communication and echolocation, a navigational strategy used by bats and some whales, have allowed them to survive in this extreme environment, but human noise presents a newer challenge.

“Their main foraging hot spots for salmon are in the northern part of the inlet, near Anchorage, and in close proximity to the airport, the Port of Alaska, and the military base. I think there are ways to adapt but it’s tricky for them and noise pollution is far from the only threat,” Brewer said.

Beluga whales in the St. Lawrence Estuary in Eastern Canada — also very noisy — have evolved to , perhaps in response to lower frequency anthropogenic noise. They also make their when it’s noisy, just like two people conversing at a party would.

In the Puget Sound region, where the endangered Southern Resident killer whales live, when whales are reported in the area. Smaller ships are legally required to keep their distance and slow down within half a mile of the whales. This program was introduced after researchers demonstrated that .

“The Port of Alaska could explore similar strategies to mitigate the impact of industry,” Brewer said. “We can’t halt shipping, but we’re trying to understand what we can do to manage these critical habitats, especially when the animals are nearby.”

Graduates at��the ����ԭ��’s��151st Commencement,��scheduled for Saturday, June 13, at Alaska Airlines Field at Husky Stadium,��will hear from��,��Class of ’83, who shared the��.����

Brunkow, who studied��molecular and cellular��biology at the UW, won the Nobel Prize for “groundbreaking discoveries concerning peripheral immune tolerance that prevents the immune system from harming the body.”��Brunkow said she plans to inspire graduates to pursue innovations and discoveries��that will make an impact around the world.��

“I’m honored to be addressing the��Class of 2026 at the ����ԭ��, the place where I discovered the joy of asking hard questions in a community that believes in possibility,” Brunkow said.��“At the UW, mentors opened lab doors, curiosity was encouraged��and persistence was taught by example. I look forward to celebrating and encouraging the next generation of explorers, creators and changemakers at the institution that sparked my own sense of what a life in science��—��and service��—��could be.”��

Brunkow��shares��the��Nobel��Prize��with��Frederick J. Ramsdell and Shimon Sakaguchi��for their combined research��into��how the immune system works. Brunkow and Ramsdell conducted research together��at��Celltech��Chiroscience,��formerly Darwin Molecular,��in Bothell,��Washington.��They��identified��a mutation in a gene called��Foxp3,��which��makes��mice susceptible to a��systemic autoimmune disorder��and is��manifested by a visible skin condition. Mutations in the human��equivalent of the Foxp3 gene are also responsible for , which has symptoms including intestinal problems,��diabetes��and scaly, itchy skin.����

Later,��Sakaguchi described the role of the��wild-type��Foxp3��gene in the development of certain white blood cells known as regulatory T cells.��These cells, which Sakaguchi discovered, keep other T cells from mistakenly attacking normal tissues. Regulatory T cells also call a ceasefire once the body gets an infection under control.��

Together, these discoveries��led��researchers to develop��a��concept��called “peripheral immune tolerance,”��through��which��the body��keeps��the immune system in check��by��avoiding��autoimmune responses that can damage healthy tissues. The��research��field��based on this concept��holds promise in advancing therapies for cancers and autoimmune��diseases,��and��improving��treatments to reduce transplant rejection.��

“Mary Brunkow’s groundbreaking work reflects the power of curiosity, persistence and discovery to improve lives around the world,” said UW President Robert J. Jones. “We are proud to count her among the ����ԭ��’s distinguished alumni and honored to welcome her back to inspire the Class of 2026 as they begin their own journeys of service, leadership and innovation.”��

Brunkow��is��currently��a��distinguished investigator and��senior program manager at the Institute for Systems Biology in Seattle. After graduating from��the UW,��she��went on to earn her doctoral degree from Princeton University in 1991.��In addition to being the featured speaker at Commencement, Brunkow��also��will��receive��the Alumna��Summa Laude��Dignata��Award, the highest honor bestowed upon a UW graduate.����
