When bean plants sense a caterpillar eating their leaves, they release gases that invite predatory wasps to help defend them. Shown here are two different species of predatory wasps attacking a caterpillar on a bean plant. Photo: Brian Behnken/91爆料

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 91爆料-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.

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 91爆料 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, 91爆料 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 91爆料 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.

91爆料 researchers launch 鈥榣ittle free pantry鈥 mapping pilot, internet-connected pantries in Seattle /news/2026/05/08/little-free-pantry-micropantry-community-fridge-pilot-app/ Fri, 08 May 2026 16:30:23 +0000 /news/?p=91624 A colorful outdoor pantry with small windows showing various foods within.
A micropantry in Seattle鈥檚 Beacon Hill neighborhood is stocked with nonperishable food for neighbors in need. In a new study, 91爆料 researchers launched an experimental mapping app designed to help users find nearby pantries and communicate with one another about sharing food. The team also outfitted several pantries with sensors that anonymously track usage and stock levels. Photo: Giacomo Dalla Chiara

Micropantries 鈥 commonly called 鈥渓ittle free pantries鈥澨 鈥 and community fridges are a frequent sight throughout Seattle and the greater Puget Sound region. One estimate suggests that they supply around 4 million pounds of food per year to neighbors in need in the Seattle area, more than the state鈥檚 largest food bank. The curbside cupboards are a decentralized, community-driven effort to fight food insecurity and reduce food waste at the neighborhood level, but their ad hoc nature limits their dependability 鈥 users don鈥檛 know when food is available without repeatedly checking, and donors don鈥檛 know what foods are needed most.

Now, anyone who interacts with micropantries or community fridges in the Seattle area can try out an experimental app, made by 91爆料 researchers, that brings a suite of new features to the micropantry network. , maps many local pantries across the region. The app also gives each pantry an activity feed where users can share food they鈥檝e donated, report on stock levels, add requests to a wish list, post photos and leave other notes. The research team also retrofitted some pantries with sensors that anonymously auto-report their usage and stock levels to the app in real time.

鈥淭his is an effort to document and quantify the phenomenon of micropantries,鈥 said , a senior research scientist at the 91爆料 . 鈥淟ots of micropantries and community fridges popped up around the time of the COVID-19 pandemic, and I was curious about who uses them and how they are used.鈥

For journalists

Dalla Chiara鈥檚 curiosity grew into an interdisciplinary pilot program funded by the National Science Foundation that draws on 91爆料 expertise from the , the , the , the and the . Over the past seven months, the team has performed minor surgery on four micropantries around Seattle: They鈥檝e added door open/closed sensors and digital scales to track the flow of food, as well as onboard microcomputers and Wi-Fi antennae to upload usage data to the app.听

The team was cognizant of privacy concerns and designed the smart pantry tech accordingly.

鈥淧utting cameras in the pantries could give us a lot of information about what specific foods are moving through the system, but that may also deter users who are concerned about privacy,鈥 said , a 91爆料 doctoral student in the Paul G. Allen School of Computer Science & Engineering who designed and built the sensor suite. 鈥淚nstead, we settled on simpler sensors that measure weight and interactions like opening the door to measure stock levels while preserving everyone鈥檚 anonymity.鈥

The researchers hope that neighbors will find new ways to connect and help one another through these tools. A user might see that stock levels are low in a nearby pantry, for example, and decide to add some food. Another user might request certain foods to accommodate their dietary restrictions.听

The sensor-equipped pantries are a small subset of the dozens of pantries throughout Seattle, but in addition to providing some neighborhoods with enhanced food tracking, they will generate aggregate data that will help Dalla Chiara鈥檚 team study donor and usage behavior. Dalla Chiara also plans to survey donors to learn more about what motivates people to provide food to pantries.

鈥淲e know that there is a lot of food insecurity in Seattle and in the United States in general,鈥 Dalla Chiara said. 鈥淏ut we know that there is also a lot of food waste 鈥 lots of people have a surplus of food. And we want to see how grassroots efforts like micropantries can address both food insecurity and waste at the same time.鈥

Dalla Chiara and his team recently completed a refit on a cold, sleeting March day at a pantry owned by Saint Paul鈥檚 Episcopal Church near Seattle Center. The church keeps the pantry regularly stocked, and rector Stephen Crippen is curious about the data the new system will produce.

鈥淚t puts numbers on what we鈥檙e actually accomplishing,鈥 Crippen said. 鈥淚t helps us get in touch with what鈥檚 going on on this street.鈥

The research team is also working with local businesses and nonprofits to encourage and track food distribution throughout the pantry network. In April, Seattle-based recycling startup ran a nonperishable food drive across Seattle and delivered 25,000 pounds of food to the ; from there, volunteers from the Cascade Bicycle Club鈥檚 distributed the food to micropantries around the city by bike, giving the network an infusion of both food and usage data. The and the nonprofit helped support the project鈥檚 community fridges effort.

Dalla Chiara recognizes that there are other grassroots online, and he doesn鈥檛 want his app to replace those services. Nor does he expect the smart pantry network to remain in service indefinitely 鈥 it costs about $150 to retrofit each pantry with sensors, and all that tech will be difficult to maintain after the study concludes in October of this year. At its core, the project is an effort to learn about micropantry usage and explore how technology might encourage sharing of resources and mutual aid systems.

鈥淲e鈥檙e trying to measure and quantify goodwill,鈥 Dalla Chiara said. 鈥淏ehind each little free pantry there is a whole system of behaviors 鈥 people trying to help one another. If we can understand that system better, we can support it better.鈥

BikeButler map creates personalized routes for riders based on preferences like speed limits and road conditions /news/2026/04/28/bikebutler-cycling-map-seattle-routes/ Tue, 28 Apr 2026 15:59:52 +0000 /news/?p=91448 The interface of a bike-mapping app.
BikeButler is a demo web app that lets users find personalized bike routes in Seattle. Cyclists plug in their destination and origin 鈥 just like in other mapping apps 鈥 and can then toggle sliders for eight attributes to create personalized route options. Above is the interface. The images on the right show different segments of the route.

Even though he wanted to bike commute from his Capitol Hill home to the 91爆料, 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 91爆料 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 91爆料 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

For instance, a cyclist can move a slider between 鈥渓ow speed limits鈥 to 鈥渉igh speed limits鈥 or between 鈥渓ots of greenery鈥 to 鈥渘o greenery.鈥 The app generates route options based on those preferences. Users can then flip through images from segments of the routes and weigh the pros and cons of taking different streets. Notes on each segment tell users how it aligns with their preferences 鈥 for example, a three-block stretch might have low speed limits and good roads but no bike lanes.听

The team April 17 at the Association for Computing Machinery Conference on Human Factors in Computing Systems in Barcelona.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 91爆料 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. So whether I鈥檓 biking with my two young children, or riding for groceries, I can find a route for that context.鈥

Q&A: 91爆料 scientists decode the logic behind cells鈥 mysterious protein stockpiles /news/2026/04/22/paul-wiggins-protein-overabundance-study/ Wed, 22 Apr 2026 16:44:07 +0000 /news/?p=91409 Small blue blobs line up along a graph of time
In a new study, 91爆料 researchers explored why cells “stockpile” some proteins that are required for growth. Shown here is a series of 鈥渉eat map鈥 images that detail the abundance of a required protein over five bacterial generations 鈥 red represents more protein within the cell, while dark blue represents less. When the researchers disabled the gene necessary to make the protein, the abundance of that protein diminished in each generation (top row). The cells in the bottom row had a functioning gene, so the protein remained abundant. Photo: H. James Cho et. al/Science Advances

As far as research subjects go, it鈥檚 not always easy to find common ground with a single-celled bacterium. Yet the more studies his model bacteria, , the more he sees surprising commonalities between their behavior and our own as humans.

鈥淚t was mortifying to be stumped for so long by what appeared to be completely counterintuitive behavior only to realize that I engage in exactly the same behavior everyday,鈥 said Wiggins, an associate professor of both physics and bioengineering at the 91爆料.听

Scientists in use experiments and modeling to understand the global principles that govern gene expression, and protein abundance in particular. In in Science Advances, Wiggins鈥 team discovered that A. baylyi cells amass huge surpluses of essential proteins, rather than taking the seemingly more efficient approach of making just enough to survive. 91爆料 News chatted with Wiggins to learn about the remarkably relatable reason for this puzzling behavior.

The cell says, 鈥淪crew it, it鈥檚 virtually free. Let鈥檚 make extra.”

Paul Wiggins91爆料 associate professor of both physics and bioengineering

This work grew out of a mystery you and your team uncovered. Tell us about that mystery.

Paul Wiggins: Genes are the blueprints for proteins 鈥 we say they 鈥渃ode for proteins.鈥 A. baylyi has a number of genes that code for proteins that we know are essential for cell growth. But we didn’t know exactly what each of these proteins do. In 2016, we were attempting to uncover these proteins’ specific functions in collaboration with the . To do this we disrupted each gene so that the cells couldn’t make any more protein 鈥 they were left with a now dwindling supply of whatever they鈥檇 previously made. Then we would watch the cells under a microscope to determine when and how cellular processes would fail.听

As an example, we knocked out a gene that coded for a protein that we found was responsible for cell wall synthesis 鈥 it makes the protein-sugar chainmail that prevents the cells from rupturing, or lysing. And you can watch the video we recorded to see what happened: The cells grew and divided for a while, but then all of a sudden they inflated and just popped.

small black blobs outlined in red grow and divide and then begin to disappear

In that example, something strange happened. We would expect the cell walls to start to fail almost immediately after the disruption happened because every time the cells divide, the remaining protein is divided among the offspring cells, so pretty quickly there wouldn鈥檛 be enough to sustain the new cell walls. However, growth continued, one generation after another, before the cells finally failed after four rounds of division!

Why did it take so long? Gene after gene showed the same pattern. We realized that each cell must have made a ton of extra proteins 鈥 far more than it needed. So after we knocked out that essential gene, the cell was able to run on fumes for a while 鈥 and was even able to pass stores of that protein on to its offspring. That finding was initially a huge surprise. We all expected, naively, that if a cell only needed a few copies of a protein to function, it would only make a few 鈥 anything more would be a waste of resources and energy. It鈥檇 be like taking a seven-day trip and packing 30 pairs of socks. And yet, this behavior seemed to be common for lots of essential genes.听

What do you think is the cause of this protein overabundance?

A portait of Paul Wiggins

PW: Baking is a good analogy. If you want to make an apple pie, you probably only buy as many apples as you need for that recipe. But you keep a large quantity of salt in your pantry. You might only need a teaspoon of salt to make any given meal, but none of us go to the store and buy salt a teaspoon at a time. Salt is so cheap and easy to store that, relative to the cost of other ingredients in your meal, it鈥檚 basically free to keep in large quantities. And critically, you don鈥檛 want to run out of salt when you鈥檙e cooking.听

We demonstrated that something analogous is happening in A. baylyi cells for most of the essential genes. Only about 30% of a cell鈥檚 essential genes code for proteins that are “expensive” in that the cells need these proteins in large numbers. It would be very costly to, say, double an already large number. These are the apples in our apple pie analogy 鈥 the cell makes just enough of those proteins to get by.听

The remaining 70% of essential genes, however, code for proteins that the cell does not need in large numbers. In fact, relative to that other 30%, the cell needs so few of these proteins that it鈥檚 basically free to produce a bunch of extras. Doubling the production of those proteins, say from 30 to 60 copies, is a drop in the bucket if the cell鈥檚 overall budget is three million proteins. So the cell says, 鈥淪crew it, it鈥檚 virtually free. Let鈥檚 make extra so we don鈥檛 run out.鈥 In some cases a cell might make 10 times more protein than it will ever need.

Why is this strategy useful for the cells?

PW: This overabundance strategy is important because otherwise a cell might fail to produce enough of something critical. Protein synthesis is an imprecise process 鈥 cells sometimes make a little more or a little less of things than they鈥檙e programmed to make. Some essential proteins are made at such low numbers that any deviation from the plan could leave a cell with zero copies of that protein. This is less of a problem for essential proteins that are made in much higher numbers.听

How do these findings support or challenge previous ideas about how cells function?

PW: Depending on who you talk to, this is either definitely wrong or completely obvious. On the one hand, it鈥檚 a really ingrained idea that organisms are always optimizing everything, which would naively suggest that cells should make exactly what they need 鈥 no more, no less. However, this is clearly not the case. Other studies have observed these kinds of protein surpluses in cells before, but it wasn鈥檛 appreciated quite how wide-spread this phenomenon was. Previously researchers proposed that overabundance might be a hedge against changing conditions 鈥 maybe cells are stockpiling proteins in case times get tough. We鈥檙e suggesting that it鈥檚 a hedge against the cells failing to make the right number of essential proteins.

Tiny cameras in earbuds let users talk with AI about what they see /news/2026/04/14/cameras-in-wireless-earbuds-vuebuds/ Tue, 14 Apr 2026 14:38:00 +0000 /news/?p=91232 Two black earbuds: one with the casing removed exposing a computer chip and tiny camera.

91爆料 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 91爆料 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 91爆料 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.

Researchers also discovered that while the vision language model was largely able to make sense of the images from each earbud, having to process images from both earbuds slowed it down. So they had the system 鈥渟titch鈥 the two images into one, identifying overlapping imagery and combining it. This allows the system to respond in one second 鈥 quick enough to feel like real-time for users 鈥 rather than the two seconds it takes with separate images.

The team then had 74 participants compare recorded outputs from VueBuds with outputs from Ray-Ban Meta Glasses in a series of tests. Despite VueBuds using low-resolution images with greater privacy controls and the Ray-Bans taking high-res images processed on the cloud, the two systems performed equivalently. Participants preferred VueBuds鈥 translations, while the Ray-Bans did better at counting objects.

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 91爆料鈥檚 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 91爆料 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 91爆料.

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.

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 91爆料 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 91爆料 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 91爆料 professor of physics and founder of QT3. 鈥淭he 91爆料 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 91爆料, 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.

UPDATE April 7, 2026:听The original version of this story omitted two 91爆料 programs that were included in the rankings: Occupational Therapy (Tied for 20th) and Physical Therapy (Tied for 31st).听

The 91爆料鈥檚 graduate and professional degree programs again were recognized as among the best in the nation, according to .

Topping this year鈥檚 list include programs at the Evans School of Public Policy & Governance, the School of Public Health, the School of Nursing, the Paul G. Allen School of Computer Science & Engineering in the College of Engineering and the College of Education. The College of Arts & Sciences and the College of the Environment also had top-rated programs.

In total, 81 graduate and professional degree programs across the 91爆料 placed in the top 35 in this year鈥檚 U.S. News rankings.

“These rankings highlight the strength and impact of the 91爆料鈥檚 graduate and professional programs,鈥 said 91爆料 President Robert J. Jones. 鈥淭hese programs equip students with the skills and knowledge to meet critical workforce needs and serve society, while demonstrating the power of higher education to advance the public good. We are proud to foster an environment where students and faculty can thrive and have a real impact on the world around them.鈥

While the 91爆料 celebrates the success and impact of the programs recognized by U.S. News 鈥 and notes that many applicants use these rankings to help them select schools and discover potential areas of study 鈥 the University also recognizes shortcomings inherent in the ranking systems.

The 91爆料 School of Law and the 91爆料 School of Medicine withdrew from the U.S. News rankings in 2022 and 2023, respectively, citing concerns that some of the methodology in the rankings for those specific disciplines incentivize actions and policies that run counter to the schools鈥 public service missions.

91爆料 leaders continue to work with U.S. News and other ranking organizations to improve their methodologies, to the extent that the organizations are open to it. Schools, colleges and departments continually reevaluate the benefits and potential shortfalls of participating in specific rankings.

Excluding the School of Law and the School of Medicine, 29 91爆料 programs placed in the top 10, and 81 are in the top 35.

听The 91爆料 this year placed in the top 10 nationwide in public affairs, biostatistics,听 nursing, computer science, education, psychology, speech and language pathology, statistics and Earth sciences.

The 91爆料鈥檚 Evans School of Public Policy & Governance has maintained its top-10 ranking for more than a decade and tied for fifth in the nation this year. The Evans School鈥檚 environmental policy program was ranked second, while public finance and budgeting as well as leadership both ranked No. 10.

The 91爆料 School of Nursing鈥檚 doctor of nursing practice program tied for No. 1 among public institutions. The School of Public Health has maintained its top-10 ranking for more than a decade, coming in this year at No. 9. The school also had three programs in the top 10: biostatistics, environmental health sciences and epidemiology.听

The 91爆料鈥檚 programs in speech and language pathology tied for No. 6.听 Two programs from the College of Education placed in the top 10. And the Paul G. Allen School of Computer Science & Engineering this year tied for seventh place overall with three programs ranked in the top 10, including artificial intelligence, programming language and systems.

U.S. News ranks biostatistics in two ways. 91爆料 ranked No. 3 as a science discipline that applies statistical theory and mathematical principles to research in medicine, biology, environmental science, public health and related fields. 91爆料鈥檚 School of Public Health ranked No. 7 in biostatistics as an area of study that trains students to apply statistical principles and methods to problems in health sciences, medicine and biology. At the 91爆料, biostatistics is a division of the School of Public Health.

In some cases, such as the College of Arts & Science and the Foster School of Business, U.S. News ranks several professional disciplines housed within academic units. Programs in dentistry are not ranked.听

Climate change may complicate avalanche risk across the Pacific Northwest /news/2026/03/23/climate-change-avalanche-risk/ Mon, 23 Mar 2026 17:07:56 +0000 /news/?p=91066 Snowy mountains with two signs in foreground. A yellow sign reads 鈥淎VALANCHE AREA鈥; a red and white sign reads 鈥淣O STOPPING OR STANDING NEXT 戮 MILE鈥.
Warming temperatures throughout the Pacific Northwest are likely to complicate avalanche forecasting in the coming years, according to a new 91爆料 study. Cooler inland regions such as Idaho and Western Montana may see increased risk from avalanches caused by layers of icy crusts that form when rain falls on snow and freezes. Photo: iStock

This winter was ; as a result, many snowy, alpine areas have seen bouts of winter rainfall where there would ordinarily only be snow. These unusual weather patterns have contributed to an abysmal ski season, but they can also set the stage for dangerous avalanches. At temperatures close to freezing, precipitation can fall as rain but freeze when it hits the snow, forming an icy crust. Snow that accumulates on top of that crust is unstable and prone to abrupt slides, causing an avalanche that can close down a major highway in moments, endanger backcountry skiers and more.

Avalanche experts in Western Washington know how to manage the risks associated with rain-on-snow events, but many of their counterparts in colder regions like Eastern Washington, Idaho and Montana are less familiar with these dynamics. New research from the 91爆料 shows that as winters in these regions warm, their snowpacks may come to resemble those of maritime areas, with more rain-on-snow events, icy crusts and complex avalanche forecasting.听

The findings in ARC Geophysical Research.

鈥淭his winter鈥檚 warmth is a harbinger,鈥 said lead author , a 91爆料 graduate student of civil and environmental engineering. 鈥淲e know that temperatures will keep rising, and our work is a red flag for cooler regions of the greater Pacific Northwest, such as Idaho and Western Montana, that aren鈥檛 used to dealing with ice crusts and their resulting avalanche problems.鈥

This creates a boundary within the snowpack that can cause snow to slip and trigger an avalanche. Photo: Clinton Alden

The study is part of a larger effort to understand the structure of snow as it accumulates, which has implications for weather and avalanche forecasting, wildlife dynamics and more.听

鈥淪now scientists are pretty good at measuring snow depth and volume,鈥 said senior author , a 91爆料 professor of civil and environmental engineering. 鈥淲e鈥檙e also pretty good at figuring out how much water you get if all that snow melts. But our models aren鈥檛 as good at representing snow structure, such as layers of different densities and crystal types that increase avalanche risks. And we really want to know how the structure of snow changes as the climate changes. That鈥檚 a tricky question that no one has tackled, particularly for rain-on-snow conditions.鈥

To dig into that question, the researchers studied how warming influences ice layer formation in seasonal snowpacks. First, they collected temperature and precipitation data captured by 53 monitoring stations across the Pacific Northwest for the past 25 years. They used a computer model to identify days when ice layers likely formed at each location. They then checked the model against real-world measurements at one of the locations 鈥 a station at Snoqualmie Pass 鈥 and found that the model matched the measurements with 74% accuracy.

Finally, they used the same model to simulate those same 25 winters at 2 C and 4 C warmer than they were, and looked for changes to the number of ice crusts across the region. , the Pacific Northwest is expected to warm by 2 C to 5 C by 2050 as compared to pre-2000 temperatures.

This map shows the change in number of 鈥渋ce crust days鈥 across the 53 monitoring sites during the simulated winter with 2 C warming.

The results were split regionally by the Cascade mountains. In colder, inland parts of the Pacific Northwest 鈥 places like Eastern Washington, Idaho and Montana 鈥 higher temperatures created more rain-on-snow days and more avalanche-prone ice layers. Locations in the warmer, maritime Cascades saw the opposite effect: Higher temperatures created slush instead of ice, potentially reducing the avalanche risk associated with ice crusts.听

The predicted snowpack changes may also impact wildlife behavior. Some foraging mammals, such as reindeer, dig down into the snow in search of food and may have a hard time breaking through an icy crust. Conversely, firm ice might provide a better running surface for animals fleeing predators. Specific regional effects will require additional study.

What鈥檚 clear now is that those who work or play in avalanche terrain in broad swaths of the Pacific Northwest 鈥 and even beyond 鈥 may need to adjust to a new set of risk factors.

鈥淚 get calls from avalanche forecasters in places like Colorado, Wyoming and Montana. They tell me they鈥檙e getting rain at 10,000 feet, which they鈥檝e never seen before,鈥 said co-author , the avalanche forecaster supervisor at Washington State Department of Transportation at Snoqualmie Pass, who earned his master鈥檚 in transportation and highway engineering at the 91爆料. 鈥淭hey want to know when to expect the onset of avalanches and when to expect the return to stability.鈥澨

Alden hopes that this research will encourage further collaboration within the avalanche forecasting community.

鈥淚鈥檇 love to see this shared with avalanche forecasters widely, both as a call to action and as a way to help them understand what their snowpack might look like in the future,鈥 Alden said.

New marine energy tech is put to the test at Harris Hydraulics Lab /news/2026/03/06/marine-energy-turbines-harris-hydraulics-uw-pnnl/ Fri, 06 Mar 2026 17:29:14 +0000 /news/?p=90849

At the 91爆料 Harris Hydraulics Lab, an odd scene plays out. Over and over again, researchers from the 91爆料 and the (PNNL) pass a small rubber model of a marine animal through a large tank filled with flowing water and fitted with a spinning turbine. On some runs, the model bonks against the turbine blades; on others, it receives a glancing blow or sails past undisturbed. When bonks or knicks occur, a small collision sensor on one of the turbine鈥檚 blades detects the impacts and plots the interactions in a computer program.

The researchers are repeatedly simulating something that they hope will rarely happen in the wild: a collision between marine wildlife like a seabird, seal, fish or whale 鈥 or submerged debris like logs 鈥 and an underwater turbine.听

鈥淲e want to make sure we鈥檙e minimizing the chances of a collision in the first place,鈥 said Aidan Hunt, a senior research engineer in mechanical engineering at the 91爆料 and member of the (PMEC). 鈥淏ut if a collision were to occur, we want to be able to detect it, and potentially avoid it, in real time. The available evidence suggests that collisions are rare, but we鈥檙e taking a 鈥榯rust-but-verify鈥 approach.鈥

Marine energy 鈥 power harvested from tides, waves and currents 鈥 has enormous potential as a clean, renewable resource. But more information is needed about how large, commercial installations of underwater turbines or power-generating buoys could affect marine wildlife, whether through increased noise in the environment, habitat change or direct interactions with equipment.听

The marine collision experiments are part of the , a collection of projects led by PNNL to study the environmental impact of marine energy.听

The work at Harris Hydraulics follows a by PNNL and the 91爆料 Applied Physics Lab using a four-foot-tall prototype turbine installed at the entrance to Sequim Bay. In that study, researchers trained an underwater camera on the turbine for 109 days and then catalogued every instance of an animal approaching or interacting with the turbine. The camera captured more than 1,000 instances of fish, birds and seals approaching the turbine blades. There were only four collisions, and all were small fish.听

鈥淭his study was a first step, but a promising one,鈥 said co-author , a research scientist at the 91爆料 Applied Physics Lab. 鈥淲e didn鈥檛 see any endangered species in our study, and the risk of collision for seals and sea birds seemed to be quite low. We鈥檙e excited to get back out there with the camera and learn even more.鈥

The Sequim Bay experiment generated hours of valuable data, but that degree of intense monitoring may not be practical in large commercial installations in the future. Cheaper impact sensors, like the ones logging bath toy impacts at Harris Hydraulics, could be a solution, researchers say.听听

The project is funded by the U.S. Department of Energy鈥檚 Hydropower & Hydrokinetics Office, through the Pacific Northwest National Laboratory鈥檚 Triton Initiative and the TEAMER program.
