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 鈥渕ovement鈥� 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听

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 鈥� examples include and the that help living cells maintain their shape 鈥� 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 鈥� 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鈥檛 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.

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 鈥� 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鈥檝e 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鈥檛 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鈥� control shrimp populations.

“The idea was, ‘Let鈥檚 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/天美影视传媒

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.

Sunbirds may look similar to hummingbirds 鈥� small, iridescent birds with thin bills 鈥� but it turns out the two are only distantly related. Sunbirds live primarily in Africa, Asia and Australia, and have a unique way to slurp up nectar. Unlike hummingbirds, which use minute movements in their bills to sip nectar, sunbirds use their tongues as a straw. published in Current Biology, a team led by researchers at the 天美影视传媒 showed that these long-billed birds can change the pressure at the base of their tongues to create suction that moves nectar through their tongues and into their mouths, a novel mechanism never before seen in vertebrates. The researchers used multiple techniques 鈥� including high-speed video of sunbirds drinking red-dyed nectar from transparent artificial flowers 鈥� to demonstrate this phenomenon across multiple sunbird species as well as build a mathematical model that describes how it works. Sunbirds pollinate the flowers they drink from, and researchers are interested in understanding how different sunbird species’ plant preferences affect the plant-pollinator networks across continents.

Seattle Fault gets 5,000 more years of sleep听

Just over 1,100 years ago an on the Seattle fault rocked 鈥� and reshaped 鈥� the Puget Sound region. It lifted the sea floor and sent a powerful tsunami through the sound. Researchers have estimated that this fault, which runs east to west beneath the middle of the city, will produce a large earthquake every 5,000 years or so. However, , recently published in Geology, pushes that estimate back to 11,000 years. The researchers extended this window by scouring submerged shorelines for evidence of significant elevation changes. The geological record at these sites dates back 11,000 years, but they only found evidence of one major earthquake. This information could be useful to those making seismic hazard maps, which help people understand the risks associated with different regions. Although other regional faults and the imposing pose more imminent risks to residents, the main Seattle fault doesn鈥檛 appear to be ready for rupture anytime soon.

The PNW has many rivers, but no system for gauging landslide dam risk

Scientists have a new tool for estimating lesser known hazards in the Pacific Northwest: and outburst floods. Landslides along rivers can block the flow of water downstream, creating a lake just above the slide area. Most landslide dams fail within 10 days, releasing trapped water in an outburst flood, which can be devastating. Last fall, 20 people died after in Taiwan. published in Natural Hazards and Earth System Sciences, UW researchers debut a mathematical approach to mapping landslide dam hazards based on valley width and projected slide size. When they applied the tool to a mountain range in Oregon, they found that roughly one-third of rivers in the study area were susceptible to landslide dams, with risk increasing in mountainous areas. If a landslide dam does form, alleviating pressure by for water to escape can help prevent flooding. Identifying high risk areas can help guide emergency response efforts following storms, earthquakes and other events that increase landslide risk.

Rubin observatory expected to spot many 鈥榠mminent impactor鈥� asteroids

Small asteroids 鈥� those 1 to 20 meters in diameter 鈥斕� hit the Earth 35-40 times per year, though they鈥檙e very rarely spotted by telescopes before impact. That could soon change: published in The Astrophysical Journal, UW astronomers calculate that the Simonyi Survey Telescope at the NSF-DOE Vera C. Rubin Observatory could discover one to two Earth-impacting asteroids annually , roughly doubling the number currently logged. The researchers expect Rubin to discover these asteroids an average of 1.5 days before impact, which is more warning time than ever before. Advance notice is extremely valuable in the case of larger asteroids that could be a threat to people or infrastructure. Because the Rubin Observatory is located in the Southern Hemisphere, it will likely discover many Earth impactors that existing asteroid surveys 鈥� concentrated in the Northern Hemisphere 鈥� miss.

Many marine microbes share a genetic toolbox for fixing supper at sea

Researchers have now identified a set of genes that allow some bacteria to process a compound, called homarine, that is abundant in the ocean and appears to play a key role in nutrient cycling. Phytoplankton produce loads of homarine, but scientists weren鈥檛 sure what became of it until now. In a recent study published in Nature Microbiology, researchers found a set of genes present in common and far-flung bacteria that convert homarine into glutamic acid, an essential building block for life. This suggests that homarine may be a vital and overlooked resource and highlights the importance of bacteria in stabilizing marine ecosystems. Previous studies also found that homarine serves as and helps small crabs . The UW team will continue studying homarine to better understand how it fits into the broader ecological landscape.

Even though he wanted to bike commute from his Capitol Hill home to the 天美影视传媒, Jared Hwang often took transit because he struggled to find a good bike route. Apps like Google Maps and Strava might suggest hilly, busy streets simply because they have bike lanes. He even headed to Reddit to crowdsource ideas.听

鈥淚 was like, surely, this cannot be the best way to do things,鈥� said , a UW doctoral student in the Paul G. Allen School of Computer Science & Engineering. 鈥淭his data is out there. We know where bike lanes are, what the roads are like, what the speed limits are. We should be able to easily access all this information at once.鈥�

So Hwang and a team of UW researchers built , a demo web app that lets users find personalized bike routes in Seattle. Cyclists plug in their origin and destination 鈥� just like in other mapping apps 鈥� and can then create personalized routes by adjusting eight sliders.听听

Researchers initially worked with four participants to understand how cyclists tend to plan their routes. Based on that, they built a prototype of BikeButler. For the basic street layout and other info, they pulled data from OpenStreetMap and government data sets. But those didn鈥檛 have information on more subjective qualities.听

For those, researchers turned to Google Street View. They used a visual language model, or VLM 鈥� a type of artificial intelligence 鈥� to analyze street images and rate subjective attributes like greenery and pavement quality. The team had the VLM rate the level of greenery on streets and then compared this with two researchers鈥� ratings. The humans agreed with each other about as much as they agreed with the VLM 鈥� about 60% of the time. Future research might try to gather individual users鈥� greenery preferences to offset this discrepancy.听

Once they鈥檇 mapped most of Seattle, the team tested the prototype with 16 participants.听

鈥淥verall the response was really positive,鈥� Hwang said. 鈥淲e found that people do, in fact, have contextual preferences. A cyclist riding for fun on a Saturday might want a safer, greener route compared with their fast work commute. People intuitively know this, but it hadn鈥檛 been established through research.鈥澨�

Researchers say future work might integrate feedback from the user study, such as the ability to drag routes to change them slightly and an option to take fewer turns. The team is currently studying how to quantify cyclists鈥� preferences around intersections and turns.

The researchers note that the quality of BikeButler鈥檚 recommendations is constrained by the recency and accuracy of the data it uses. For instance, a new bike lane might not yet appear on a map, or it could appear in OpenStreetMap but not Google Street View. Also, since the team planned this as a proof of concept, BikeButler is limited to Seattle, though it could be expanded to other areas.听

鈥淚鈥檓 a lifelong biker and bike commuter,鈥� said senior author , a UW professor in the Allen School. 鈥淲hat excites me most about Jared鈥檚 work is how it points to a future where we receive route choices individualized to our preferences.

The Ecological Society of America on Wednesday awards. , a 天美影视传媒 assistant professor of environmental and forest science, was named an Early Career Fellow, which recognizes scientists for contributions to advancing and applying ecological knowledge within eight years of completing a doctorate.

Willing studies how microbes respond, and help plants cope with, environmental change. focuses on fungi and other microbes living near plant roots. Much like the gut microbiome, these communities play a critical role in plant nutrition, immune function and overall forest health.

Willing鈥檚 lab focuses on understanding these communities and how they are shifting with climate change. Her research integrates methods from various scientific disciplines to gain insight into the ecosystem-wide impact of fungi.

鈥淚 work across pretty diverse fields, from fungal ecology to plant and forest ecology,鈥� Willing said. 鈥淚ntegrating everything together is challenging, but I think it’s a critical intersection to study right now and this award is a nice acknowledgement of that.鈥�

As a Faculty Fellow, Willing also collaborates with federal, state and tribal agencies to incorporate fungi into climate adaptation planning.

Many of her lab鈥檚 projects examine responses to climate change. For example, one of Willing鈥檚 current grad students is studying fungi in post-fire ecosystems.

Some fungal groups are fire-adapted, meaning that they can withstand wildfire better than others. After wildfire, the soil often becomes hydrophobic, which causes water to run off the surface instead of soaking in. This increases the risk of erosion, among other consequences. Fungi help seedlings to establish and stabilize the soil by helping it retain water.

Early findings from her lab indicate that prolonged fire suppression, a stewardship strategy intended to minimize wildfire impacts, can limit microorganisms fire tolerance, which then exacerbates the damage caused by a fire.

鈥淭here are lots of different nuances that we鈥檙e really just starting to understand,鈥� Willing said.

She hopes this work can help inform future forest management practices. Although there are many mushroom enthusiasts in the Pacific Northwest, Willing is one of few scientists in the region studying how these organisms fold into broader ecosystems.

Most of the data on microbial communities was collected within the past 20 years or so, which makes it difficult to gauge how these organisms are responding to climate change. Another project in Willing鈥檚 lab involves conducting genetic analyses on preserved plant specimens to establish a baseline for fungal health.

鈥淥ur understanding of what fungal and bacterial communities were like before the onset of rapid warming is really limited,鈥� Willing said.

Building this baseline will help researchers see how microbial communities are evolving and reveal management opportunities.

Without fungi, life on Earth couldn鈥檛 exist as we know it. Dead logs and fallen leaves would simply accumulate, with nothing to break them down and return their nutrients to the soil.

鈥淔ungi are involved in everything,鈥� Willing said. 鈥淚n the cycle of life, they are at the beginning, helping plants to take root across every ecosystem on Earth, and at the end, helping to create lush soils for future life to flourish.鈥�

ESA will acknowledge and celebrate fellows during a ceremony on July 27 at the annual meeting in Salt Lake City. Early Career Fellows are elected for five years.

天美影视传媒 researchers developed the first system that incorporates tiny cameras in off-the-shelf wireless earbuds to allow users to talk with an AI model about the scene in front of them. For instance, a user might turn to a Korean food package and say, 鈥淗ey Vue, translate this for me.鈥� They鈥檇 then hear an AI voice say, 鈥淭he visible text translates to 鈥楥old Noodles鈥� in English.鈥�

The prototype system called VueBuds takes low-resolution, black-and-white images, which it transmits over Bluetooth to a phone or other nearby device. A small artificial intelligence model on the device then answers questions about the images within around a second. For privacy, all of the processing happens on the device, a small light turns on when the system is recording, and users can immediately delete images.听

The team will April 14 at the Association for Computing Machinery Conference on Human Factors in Computing Systems in Barcelona.听

鈥淲e haven鈥檛 seen most people adopt smart glasses or VR headsets, in part because a lot of people don鈥檛 like wearing glasses, and they often come with , such as recording high-resolution video and processing it in the cloud,鈥� said senior author , a UW professor in the Paul G. Allen School of Computer Science & Engineering. 鈥淏ut almost everyone wears earbuds already, so we wanted to see if we could put visual intelligence into tiny, low-power earbuds, and also address privacy concerns in the process.鈥�

Cameras use far more power than the microphones already in earbuds, so using the same sort of high-res cameras as those in smart glasses wouldn鈥檛 work. Also, large amounts of information can鈥檛 stream continuously over Bluetooth, so the system can鈥檛 run continuous video.听

The team found that using a low-power camera 鈥� roughly the size of a grain of rice 鈥� to shoot low-resolution, black-and-white still images limited battery drain and allowed for Bluetooth transmission while preserving performance.

There was also the matter of placement.听

鈥淥ne big question we had was: Will your face obscure the view too much? Can earbud cameras capture the user鈥檚 view of the world reliably?鈥� said lead author , who completed this work as a UW doctoral student in the Allen School.听

The team found that angling each camera 5-10 degrees outward provides a 98-108 degree field of view. While this creates a small blind spot when objects are held closer than 20 centimeters from the user, people rarely hold things that close to examine them 鈥� making it a non-issue for typical interactions.

Sixteen participants also wore VueBuds and tested the system鈥檚 ability to translate and answer basic questions about objects. VueBuds achieved 83-84% accuracy when translating or identifying objects and 93% when identifying the author and title of a book.

This study was designed to gauge the feasibility of integrating cameras in wireless earbuds. Since the system only takes grayscale images, it can鈥檛 answer questions that involve color in the scene.听

The team wants to add color to the system 鈥� color cameras require more power 鈥� and to train specialized AI models for specific use cases, such as translation.听听

鈥淭his study lets us glimpse what鈥檚 possible just using a general purpose language model and our wireless earbuds with cameras,鈥� Kim said. 鈥淏ut we鈥檇 like to study the system more rigorously for applications like reading a book 鈥� for people who have low vision or are blind, for instance 鈥� or translating text for travelers.鈥澨�

Even on a campus like the 天美影视传媒鈥檚 鈥� home to particle accelerators, wave tanks and countless other bespoke pieces of equipment 鈥� the machinery in the stands out. Take the dilution fridge, a large, white, cylindrical device that can cool a small chamber to one hundredth of a kelvin above absolute zero 鈥� the coldest possible temperature in the universe.听

鈥淭his is the coldest fridge money can buy,鈥� said , a UW assistant professor of electrical and computer engineering and the former director of the lab, which goes by the nickname QT3. 鈥淲hen it鈥檚 running, the chamber inside this device is about 100 times colder than outer space. At that temperature, it鈥檚 much easier to study and manipulate a material鈥檚 quantum properties.鈥�

The lab also houses a photon qubit tabletop lab: a nondescript set of boxes, lasers and lenses that can demonstrate the 鈥渟pooky鈥� 鈥� a term scientists actually use 鈥� phenomenon known as quantum entanglement, where two particles appear to communicate instantaneously with each other despite being physically apart.

Or there鈥檚 the lab鈥檚 latest acquisition, the scanning tunneling microscope, which can image individual atoms within a solid material, allowing researchers to study the structure of materials at the smallest scales.

An interdisciplinary group of researchers has been marshalling resources and expertise to create QT3 for three years, and now, the lab is opening its doors as a unique one-stop shop resource for quantum researchers and educators at the UW.

鈥淭he idea of this lab is to improve access to quantum hardware,鈥� Parsons said. 鈥淚t’s rather hard to acquire equipment like this. And there are a lot of researchers that may have good ideas that they want to test, but don鈥檛 have the resources yet for their own equipment. So we鈥檙e inviting researchers, initially from across campus, but also from other universities and from industry, to come in and test their ideas. This can be a hub for quantum experts to share their ideas and collaborate.鈥�

The lab also boasts hardware that can demonstrate known quantum principles and techniques, making it useful for students in quantum fields. In addition to the entanglement device, Parsons鈥� students developed a machine that can suspend charged particles 鈥� in this case, tiny grains of pollen 鈥� in midair using electric fields. Researchers use the same technique to trap single atoms and manipulate their quantum properties, making the lab鈥檚 ion-trapping machine good practice for more complex work.

Some students even work at the lab through an undergraduate staffing program, and have helped install instrumentation, write code to power equipment and build parts for custom microscopes. The program provides yet another avenue for students to get hands-on experience with unusual machinery and techniques.听

鈥淨uantum mechanics is inherently counterintuitive, and that makes it a powerful teaching tool,鈥� Parsons said. 鈥淚n the QT3 lab, students will encounter systems where their everyday intuition breaks down, and they must rely on careful reasoning and experimentation instead. They learn how to debug when results don鈥檛 match expectations, how to test simple cases and how to build understanding about hardware step by step.鈥�

The cosmically cold dilution fridge remains something of a centerpiece, even as the lab fills up with specialized equipment. The extreme environment within the device strips heat, light and other stray energy away from materials, allowing researchers to observe the peculiar quantum properties that remain. One such property is superposition, or the ability of a particle like an electron to maintain multiple mutually exclusive properties at the same time. Scientists use superposition to create a powerful, tiny piece of technology: a quantum bit, or qubit.听

鈥淭raditional computers use bits, which can only be one or zero. A qubit, on the other hand, we can make one plus zero,鈥� Parsons said. 鈥淚t’s both at the same time, and only when we measure it do we find out which one it is. We can use this unusual property to build a new class of computers that excel at tasks like communications and encryption.鈥�

QT3 is part of a collaborative effort to solidify UW as a leader in quantum research and applications. Most of the lab hardware was funded by a congressional earmark championed by Senator Maria Cantwell鈥檚 office. Departmental funding from across the College of Engineering and the College of Arts and Sciences helped rehab the lab space. The National Science Foundation provided seed funding for the instructional lab equipment.

The UW has also spent the past decade investing heavily in faculty with quantum expertise.

鈥淰ery few places have expertise across the full quantum stack, from materials up to algorithms,鈥� said , a UW professor of physics and founder of QT3. 鈥淭he UW has quantum faculty in electrical and mechanical engineering, physics, computer science, materials science and chemistry. Our faculty work on superconducting qubits, spin defects, photons, trapped ions, neutral atoms and topological qubits. Our advantage is the breadth of our investment.鈥�

The lab is now available to researchers and students across the UW, and private companies are encouraged to reach out about partnering. Parsons has already used the lab to teach a graduate-level class in electrical and computer engineering for students who included employees from Boeing, Microsoft and quantum computing company IonQ. The lab is hiring for a full-time manager to maintain the equipment and help users make the most of the facility.听

鈥淗ere in academia, we can improve the building blocks for applied technologies like quantum computing, and then transfer those learnings to industry for further scaling,鈥� Parsons said.

Nautilus and Allonautilus cephalopods and their extinct ancestors have been drifting through of the ocean for more than 500 million years. Researchers have spent the last 40 years trying to understand how these mysterious “living fossils” thrive in areas with limited nutrients. published in Scientific Reports, a UW-led team documented new habits and habitats for current Nautilus and Allonautilus species. These creatures appear to live in deeper water than their extinct cousins did, and the younger ones live twice as deep as the fully mature adults. Nautilus and Allonautilus species scavenge their food and never stop moving. While a few species migrate hundreds of meters down at dawn and then back up at dusk every day, the team found that most species aren’t quite as intrepid. The researchers also describe a new population of Allonautilus in waters off the island , one of several populations thriving due to hunting restrictions inspired in part by research efforts from this team.

Green clay tennis courts become carbon negative after 10 years

The United States has around a quarter of a million tennis courts, 40,000 of which are helping mitigate greenhouse gas emissions. Green clay tennis courts, an alternative to traditional hard courts and the red clay courts popular in Europe, are constructed with a type of rock that reacts with carbon dioxide and water to sequester carbon as a stable dissolved salt. In , UW researchers show that in the U.S., green clay courts remove 25,000 metric tons of carbon dioxide from the atmosphere each year and 80% of green clay courts make up for construction emissions within 10 years. Moving forward, the researchers hope to experiment with other materials that also remove carbon dioxide without compromising performance for players.

Temperature dynamics, not just extremes, impact heat tolerance in mussels

Intertidal mussels, forming bumpy layers on shoreline rocks, withstand significant temperature swings as the tide ebbs and flows. These creatures live in one of the most thermally variable environments on Earth, but a new study shows that the rate, timing and duration of heating and cooling impact their metabolic rate, a proxy for overall health. At the UW鈥檚 , researchers exposed mussels to temperature regimens with equal highs and lows but different patterns of change. Even when the average temperature for a set period was the same, the mussels鈥� response was distinct. These results, , show that predicting how marine organisms respond to climate change means considering how temperature changes over time, not just how warm it gets.

When algae stop growing, bacteria start swarming

Tiny geometric algae, called , produce nearly a quarter of the world鈥檚 organic matter by photosynthesis. In the microscopic marine universe, diatoms coexist with both harmful and helpful bacteria. A new study, , describes how a recently identified species of marine bacteria targets diatoms based on growth phase and nutrient availability. Growing diatoms can resist bacterial attacks, but when growth ceases, the bacteria modulate their gene expression patterns to become aggressive 鈥� first swimming and releasing compounds that damage the diatom and then clustering around them to feed. Bacteria can also overcome the diatom鈥檚 defenses in nutrient-rich environments. These findings highlight the dynamic relationship between bacteria and algae in the lab. Moving forward, researchers will explore what, if anything, changes in a more complex environment.

Humans look to nature for sustenance and nourishment 鈥� food, water, energy, transportation, culture, tradition, adventure and so on. With the population of the United States now exceeding 340 million, humans are demanding more of the natural world than ever before. To understand the consequences, researchers set an ambitious goal: a wellness check on nature.

Nature is a sweeping category that includes everything from massive mountains to tiny urban gardens. Its health can鈥檛 be summarized in just a few words. In fact, it took researchers 868 pages, split into 13 chapters, to report the condition of lands, waters, wildlife, and biodiversity and describe links to human health and safety, culture, economy, and national security.

The new report, , is available for public comment and scientific review until May 30.

鈥淭he Nature Record tells an honest story,鈥澨� said , director of The Nature Record and interim executive director of the UW鈥檚 EarthLab. 鈥淚t does not shy away from the scale of change we are seeing in nature 鈥� but it also shows that our choices matter, and that there are real, tangible ways to restore and sustain the systems we depend on.鈥�

The preliminary findings are a mixed bag. On one hand, the report details a long history of resource extraction and habitat loss that will be difficult to reverse. At the same time, it shows how restoration and Indigenous stewardship approaches can help turn things around.

For example, the report states that approximately 50% of U.S. land is used for agriculture. This means farmers and ranchers must be involved in efforts to protect ecosystems and preserve biodiversity, Levin said.

The U.S. has millions of miles of rivers, which are fragmented by tens of thousands of large dams and as many as 2 million small dams and culverts.

Damming rivers disrupts fish migration and degrades ecosystem health. Ecological concerns have spurred hundreds of dam removals in the past decade, after which rivers quickly rebounded. In some places, fish have returned to spawning grounds that were inaccessible for generations.

鈥淭he assessment documents many examples where ecosystems and communities are recovering together,鈥� Levin said. 鈥淭hese success stories show that change is possible when science, policy and communities align.鈥�

The project began in 2022 following an executive order calling for an assessment of nature. Levin, selected to lead the effort, assembled a national team of experts to work on what was then called the National Nature Assessment.

Then, in January 2025, just weeks before the team was due to deliver a first draft, the effort came to a screeching halt when the federal government canceled the effort.

Undeterred, the team, including more than 170 scientists and experts, decided to continue working independently. They published a draft of The Nature Record in March.

鈥淲e built this to be useful,鈥� Levin said. 鈥淎nd the only way it becomes truly useful is if people engage with it 鈥� question it, add to it, and help shape what comes next.鈥�

He encourages people of all backgrounds to engage with the report and share feedback on the clarity, relevance and thoroughness, including representation of diverse perspectives.

In addition to documenting how humans are changing nature, the record provides important insights into how nature influences quality of life. Access to nature varies widely across the U.S. 鈥� the benefits of nature are not equally shared, nor is the burden of going without. Social and historical factors often determine whether communities enjoy greenspaces and clean drinking water, among other essentials.

鈥淭his assessment reflects not just the state of nature, but the relationships people have with it,鈥� said deputy director , principal research scientist at the UW鈥檚 EarthLab. 鈥淲e want people to see themselves in this work 鈥� whether through their communities, their values, or the places they care about 鈥� and to help shape how it evolves.鈥�
