Forest managers in the eastern Cascades selectively thin forests to promote wildfire resilience. New research from the UW shows that the same process can also increase seasonal snowpack, providing some relief to drought-prone areas throughout central Washington.
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.
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.
A new smart glove from the UW Wearable Intelligence Lab could help physical therapy patients track progress and train robotic hands to grasp.
Lucas Meza, an assistant professor of mechanical engineering at the University of Washington, started his lab to build a new generation of tough and light nanomaterials inspired by natural materials like wood, shell and bone. Instead, he discovered “big gaps” in our basic understanding of what makes a material tough or brittle. Meza spoke to UW News about his strange and surprising journey into the nano realm.
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.
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.
Targeted drug delivery is a powerful and promising area of medicine. Therapies that pinpoint precise areas of the body can reduce the medicine dosage and avoid potentially harmful “off target” effects. Researchers at the UW took a significant step toward that goal by designing proteins with autonomous decision-making capabilities. By adding smart tail structures to therapeutic proteins, the team demonstrated that the proteins could be “programmed” to act based on the presence of specific environmental cues.
UW researchers discuss their study which surveyed 166 gamers about how video games sparked meaningful changes in their lives.
New research from the UW tested how much a car owner’s perception of public charger reliability influences their willingness to buy their first EV. The results were dramatic: Participants with a negative view of public charging were far less likely to choose an EV than those with a moderate view.
In her new book, Katharina Reinecke explores how “digital culture shock” manifests in the world, in ways innocuous and sometimes harmful.
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.
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.
Antimicrobial resistance is a lurking threat in hospitals around the world. As more strains of bacteria and other microbes evolve defenses against available drugs, more patients run the risk of contracting infections that defy treatment. Now, University of Washington researchers offer new insights into measures currently used to control the spread of antibiotic resistant bacteria and other infectious agents in health care facilities.
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.
UW professor of aeronautics and astronautics Jim Hermanson took a ride Wednesday morning aboard a U.S. Navy Boeing F/A-18 Super Hornet — better known as one of the Blue Angels.
Researchers at the University of Washington and Microsoft developed a new type of low-carbon concrete by mixing dried, powdered seaweed with cement. The seaweed-fortified cement has a 21% lower global warming potential while retaining its strength.
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.
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 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.
Two University of Washington researchers are developing treatments that aim to simultaneously treat cancer and improve patients’ quality of life. For World Cancer Day, UW News asked them to discuss their novel materials and how these materials can treat both the cancer and the patient.
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.
