A team led by University of Washington researchers has created DopFone, a system that uses an off-the-shelf smartphone’s existing speaker and microphone to accurately estimate fetal heart rate. The phone mimics a Doppler ultrasound, emitting a tone and listening for the subtle variations in its echo caused by fetal heart beats. A machine learning model then estimates the heart rate.
The Vera C. Rubin Observatory has issued its first real-time alerts of changes in the night sky. The ultrafast alerting system, developed at the UW, will eventually detect up to seven million changes in the cosmos every night and notify scientists around the world.
A UW and Ai2 research team built OpenScholar, an open-source AI model designed specifically to synthesize current scientific research. In tests, OpenScholar cited sources as accurately as human experts, and 16 scientists preferred its response to those written by subject experts 51% of the time.

UW researchers analyzed the checkout data from the last 20 years of the 93 authors included in the post-1945 volume of “The Norton Anthology of American Literature,” which is assigned in U.S. English classes more than any other anthology. Sci-fi was especially popular.
New research from the UW and the Toyota Research Institute explores how drivers trade off between cognitive tasks, driving and using the vehicle’s touch screen. Researchers placed participants in a driving simulator and had them complete memory tests while interacting with the simulator’s touch screen.
A new University of Washington study suggests that AI could learn cultural values by observing human behavior, similar to how children learn by watching and interacting with adults. Researchers had AI systems observe two cultural groups playing a video game. The AI systems were able to learn each group’s degree of altruism and apply this to a new situation.
Researchers at the UW have developed AI-powered headphones that automatically isolate conversation partners in a noisy soundscape. The system employs AI models that listen for the back-and-forth pattern of conversation and mute voices that aren’t following the established rhythm.
A web-based method was shown to mitigate political polarization on X by nudging antidemocratic and extremely negative partisan posts lower in a user’s feed. The tool, which is independent of the platform, has the potential to give users more say over what they see on social media.
In a new UW study, 528 participants worked with simulated AI systems to select job candidates. The researchers simulated different levels of racial biases for resumes from white, Black, Hispanic and Asian men. Without suggestions, participants’ choices exhibited little bias. But when provided with recommendations, participants mirrored the AI’s biases.
Researchers at the UW have created a recyclable, flexible and self-healing composite material that could replace traditional circuit boards in future generations of wearable electronics.
The Royal Swedish Academy of Sciences on Tuesday awarded the 2025 Nobel Prize in Physics jointly to John Clarke, Michel H. Devoret and John M.

In a recent paper, University of Washington researchers argue that a key standard for deploying medical AI is transparency — that is, using various methods to clarify how a medical AI system arrives at its diagnoses and outputs.
The goals of those developing AI systems for the climate and those working on the front lines of climate advocacy don’t necessarily align. To compare the two groups, UW researchers interviewed nine people who are developing AI for sustainability and 10 climate advocates.
New research led by the University of Washington provides clear evidence that highly walkable areas lead to significantly more walking. Authors compared the steps per day of 5,424 people who moved one or more times among 1,609 U.S. cities. Across all relocations, when the Walk Score rose or fell more than 48 points, average steps increased or decreased by about 1,100 per day.
University of Washington researchers recruited self-identifying Democrats and Republicans to make political decisions with help from three versions of ChatGPT: a base model, one with liberal bias and one with conservative bias. Democrats and Republicans were both likelier to lean in the direction of the biased chatbot they were talking with than those participants who interacted with the base model.
University of Washington researchers developed the game AI Puzzlers to show kids an area where AI systems still typically and blatantly fail: solving certain reasoning puzzles. In the game, users get a chance to solve puzzles by completing patterns of colored blocks. They can then ask various AI chatbots to solve and have the systems explain their solutions — which they nearly always fail to do accurately.
A new era of astronomy and astrophysics began Monday when the first images captured by the NSF–DOE Vera C. Rubin Observatory were released, demonstrating the extraordinary capabilities of the new telescope and the world’s largest digital camera.
In 2023, University of Washington researchers recruited a group of 29 laid-off U.S. tech workers to discuss the effects of recent mass layoffs on employees. Overall, the group was ambivalent about tech work. They said it was often unfulfilling, despite their plans to continue in the industry.
UW researchers designed a headphone system that translates several people speaking at once, following them as they move and preserving the direction and qualities of their voices. The team built the system, called Spatial Speech Translation, with off-the-shelf noise-cancelling headphones fitted with microphones.
A UW-led team has developed a system, called ProxiCycle, that logs when a passing car comes too close to a cyclist (four feet or less). A small, inexpensive sensor plugs into bicycle handlebars and tracks the passes, sending them to the rider’s phone. The team tested the system for two months with 15 cyclists in Seattle and found a significant correlation between the locations of close passes and other indicators of poor safety, such as collisions.
A new data set called OS-CONNECT maps sidewalks and other pedestrian paths statewide, from Forks on the Olympic Peninsula to Clarkston in the southeast. In House Bill 1125, the Washington State Legislature assigned the UW’s Taskar Center for Accessible Technology to build the data set, which was completed well ahead of its projected 2027 goal.
Researchers deployed a robotic feeding arm in a pair of studies outside the lab. In the first, six users with motor impairments used the robot to feed themselves a meal in a UW cafeteria, an office or a conference room. In the second study, a community researcher and co-author on the research used the system at home for five days.
UW doctoral student Brett Halperin interviewed picketing film workers about AI during the 2023 strikes.
UW researchers developed a new system for turning used coffee grounds into a paste, which they use to 3D print objects, such as packing materials and a vase. They inoculate the paste with Reishi mushroom spores, which turn the coffee grounds into a resilient, fully compostable alternative to plastics.
A UW team studied how AI systems portray teens in English and Nepali, and found that in English language systems around 30% of the responses referenced societal problems such as violence, drug use and mental illness. The Nepali system produced fewer negative associations in responses, closer to 10% of all answers.
UW researchers have developed IRIS, a smart ring that allows users to point and click to control smart devices. The prototype Bluetooth ring contains a small camera which sends an image of the selected device to the user’s phone. The user can control the device by clicking a small button or — for devices with gradient controls, such as a speaker’s volume — rotating the ring.
University of Washington researchers created a method for training AI systems — both for large language models like ChatGPT and for robots — that can better reflect users’ diverse values. It predicts users’ preferences as they interact with it, then tailors its outputs accordingly.

Voices and sounds outside the bubble are quieted an average of 49 decibels, even if they’re louder than those in the bubble.
University of Washington researchers found significant racial, gender and intersectional bias in how three state-of-the-art large language models ranked resumes. The models favored white-associated names 85% of the time, female-associated names only 11% of the time, and never favored Black male-associated names over white male-associated names.
University of Washington researchers created MobiPrint, a mobile 3D printer that can automatically measure a room and print objects onto the floor. The team’s graphic interface lets users design objects in a space that the robot has mapped out. The prototype, which the team built on a modified consumer vacuum robot, can add a range of objects to rooms.
