Hummingbird bills — their long, thin beaks — look a little like drinking straws. But new research shows just how little water, or nectar, that comparison holds. University of Washington scientists have discovered that the hummingbird bill is surprisingly flexible. While drinking, a hummingbird rapidly opens and shuts different parts of its bill simultaneously, engaging in an intricate and highly coordinated dance with its tongue to draw up nectar at lightning speeds.
An analysis of the health care records of 1.2 million Southern California residents found that higher long-term smoke exposure was associated with a significant increase in the odds that a person would be diagnosed with dementia. Exposure to non-wildfire PM2.5 also increased a person’s risk of dementia, but to a much lesser degree.
A new study led by the University of Washington has for the first time quantified the risk for whale-ship collisions worldwide for four geographically widespread ocean giants that are threatened by shipping: blue, fin, humpback and sperm whales. In a paper published online Nov. 21 in Science, researchers report that global shipping traffic overlaps with about 92% of these whale species’ ranges. Only about 7% of areas at highest risk for whale-ship collisions have any measures in place to protect whales from this threat. These measures include speed reductions, both mandatory and voluntary, for ships crossing waters that overlap with whale migration or feeding areas.
A routine inspection of the University of Washington’s animal care and use program conducted by the United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) on Oct. 8 identified issues that the UW had self-reported and corrected before the inspection took place.
University of Washington researchers developed a system for detecting subtle biases in AI models. They found seven of the eight popular AI models they tested in conversations around race and caste generated significant amounts of biased text in interactions — particularly when discussing caste. Open-source models fared far worse than two proprietary ChatGPT models.
UW assistant professor Sheng Wang discusses BiomedParse, an AI medical image analysis model that works across nine types of medical images to better predict systemic diseases. Medical professionals can load images into the system and ask the AI tool questions about them in plain English.
The University of Washington named Deborah H. Fuller, a professor of Microbiology at the UW School of Medicine, the next director of the Washington National Primate Research Center. Fuller started in the new role on Nov. 1, said Vice Provost of Research Mari Ostendorf.
A team led by researchers at the University of Washington has created a headphone prototype that allows listeners to hear people speaking within a bubble with a programmable radius of 3 to 6 feet. Voices and sounds outside the bubble are quieted an average of 49 decibels, even if they’re louder than those in the bubble.
The University of Washington’s annual Veterans Day ceremony, held on Monday at the Medal of Honor Memorial near Parrington Hall, honored those who have served and featured music by the Husky Marching Band. The Monday ceremony kicked off a number of events during Veteran Appreciation Week at UW. UW alum Dr. Dana Covey, ’84, U.S. Navy, was honored with the Distinguished Alumni Veteran Award by Provost Tricia Serio. Covey is considered one of the world’s leading authorities on battlefield care…
A team led by scientists at the University of Washington and the University of Aberdeen attached tiny “backpack” trackers to hummingbirds in the Colombian Andes to learn more about their movements. As they report in a paper published Oct. 10 in the journal Ecology and Evolution, the tracking system will aid conservation efforts in this region by revealing the previously hidden movements of hummingbirds and other small animals.
As Earth faces unprecedented climate change, a look into the planet’s deep past may provide vital insights into what may lie ahead. But knowledge of the natural world millions of years ago is fragmented. A 15-year study of a site in Bolivia by a joint U.S.-Bolivia team has provided a comprehensive view of an ancient ecosystem when Earth was much warmer than it is today, and changed how we look at the Andes.
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.
Across its three campuses, the University of Washington generated a total impact on the state’s economy of $20.9 billion in fiscal year 2023, according to an economic contribution analysis released today. The study further concludes that the economic activity of the UW system supported or sustained 111,951 jobs statewide.
The University of Washington on Tuesday announced a transformational gift from the estate of Stan and Alta Barer to the School of Law, expanding the couple’s namesake institute: The Barer Institute for Leadership in Law & Global Development. The gift will support the recruitment of additional international fellows, increase scholarships, endow faculty positions and create more global impact.
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.
Researchers think meltwater beneath Martian ice could host microbial life. New results show that dusty ice could allow deeper layers to melt, while allowing enough sunlight through to support photosynthesis.
Final reports from the University of Washington’s task forces on antisemitism and Islamophobia were released Tuesday. The task forces were established by UW President Ana Mari Cauce on March 7, 2024, with the goal of assessing “how students, faculty and staff are experiencing discrimination or harassment because they are Jewish and/or Palestinian, Middle Eastern or Muslim on our campus, and to what degree they feel the climate is supportive and welcoming.”
The University of Washington’s newest freshman class is the most diverse in the school’s 164-year history, and the incoming class at UW Bothell is the largest since the school first welcomed students in 1990, while UW Tacoma’s enrollment increased 4% over last year.
Researchers from the University of Washington have discovered a new way to help liquid flow in only one direction, but without using the flaps that engines and our circulatory system rely upon to prevent fluid backup. The team built a flexible pipe with an interior helical structure inspired by the anatomy of shark intestines — creating a prototype inspired by biology but with applications in engineering and medicine.
Every year, undergraduates at the University of Washington start their college experience, often in cavernous classrooms, learning alongside dozens, if not hundreds, of their peers. Research shows that taking these courses — some prerequisites and other classes on popular topics — can make students feel isolated, scared and not up to the task.
Daniel Jackson Evans, a man whose impact on the state of Washington and the University of Washington spans decades and is memorialized in his namesake, the Daniel J. Evans School of Public Policy & Governance, died Sept. 20, 2024. He was 98.
The University of Washington will welcome its incoming classes and their families on Sunday, Sept. 22 at the University’s annual New Student Convocation, which will be held in Alaska Airlines Arena at Hec Edmundson Pavilion.
In just eight years, the UW Population Health Initiative has funded 227 innovative, interdisciplinary projects. With the Initiative now a third of the way into its 25-year vision, UW News checked in with three projects that recently received funding to scale their efforts.
Scientists have discovered the cuisine preferences of two resident killer whale populations, also known as orcas: the Alaska residents and the southern residents, which reside primarily in the Salish Sea and off the coast of Washington, British Columbia, Oregon and northern California. The two populations show broad preference for salmon, particularly Chinook, chum and coho. But they differ in when they switch to hunting and eating different salmon species, as well as the other fish species they pursue to supplement their diets. This information could aid conservation efforts for southern resident killer whales, which remain critically endangered due to pollution, loss of salmon habitat and other human-caused factors that disrupt their hunting and reproductive capabilities.
Mild fall temperatures this week helped welcome the first group of students who moved into University of Washington residence halls and apartments. More than 10,000 students are expected to live in UW housing this year, including more than 77.5% of the freshman class. This year’s incoming class is expected to be around 7,150, according to preliminary information.
UW researchers have developed a flexible, durable electronic prototype that can harvest energy from body heat and turn it into electricity that can be used to power small electronics, such as batteries, sensors or LEDs. This device is also resilient — it still functions even after being pierced several times and then stretched 2,000 times.
New research led by the University of Washington and the National Oceanic and Atmospheric Administration has revealed how underwater noise produced by humans may help explain why southern resident orca populations have not recovered from historic lows. In a paper published Sept. 10 in Global Change Biology, the team reports that underwater noise pollution — from both large and small vessels — forces northern and southern resident orcas to expend more time and energy hunting for fish. The din also lowers the overall success of their hunting efforts. Noise from ships likely has an outsized impact on southern resident orca pods, which spend more time in parts of the Salish Sea with high ship traffic.
New research from the University of Washington found lockdowns during the COVID-19 pandemic resulted in unusually accelerated brain maturation in adolescents. This maturation was more pronounced in girls. When measured in terms of the number of years of accelerated brain development, the mean acceleration was 4.2 years in females and 1.4 years in males.
An international team led by researchers at the University of Washington has uncovered surprising details about mosquito mating, which could lead to improved malaria control techniques and even help develop precision drone flight. In a paper published Aug. 30 in the journal Current Biology, the team revealed that when a male Anopheles coluzzii mosquito hears the sound of female-specific wingbeats, his eyes “activate” and he visually scans the immediate vicinity for a potential mate.
NASA’s upcoming Nancy Grace Roman Space Telescope will look for “fossils” of galaxy formation by conducting high-resolution imaging studies. Through a grant from NASA, astronomers are designing a set of possible observations called RINGS — the Roman Infrared Nearby Galaxies Survey — that would collect these images, and the team is producing publicly available tools that the astronomy community can use once Roman launches and starts collecting data.
A team led by University of Washington researchers found that large language models, such as ChatGPT, can make social media bots more sophisticated at evading detection. But these models can also improve systems that detect bots.
The overlap between humans and animals will increase substantially across much of the planet in less than 50 years due to human population growth and climate change, according to a collaborative study by scientists at the University of Michigan, the University of Washington and University College London. By 2070, the overlap between humans and more than 22,000 vertebrate species will rise across nearly 57% of Earth’s land, according to the team.
Pack Ventures, a new venture capital fund that is collaborating with the University of Washington, aims to help entrepreneurs launch new innovations and grow startups that emerge across the UW, while also giving Husky alumni access to investment opportunities.
The Colorado River and its tributaries provide water for hydropower, irrigation and drinking water in seven U.S. states and Mexico. But since 2000, water managers have struggled to predict how much water will come from the snowpack. The problem lies with the lack of rainfall in the spring, according to new research from the UW.
A new study has found galaxies with more neighbors tend to be larger than their counterparts that have a similar shape and mass, but reside in less dense environments. In a paper published Aug. 14 in the Astrophysical Journal, the team, which used a machine-learning algorithm to analyze millions of galaxies, reports that galaxies found in denser regions of the universe are as much as 25% larger than isolated galaxies. The findings resolve a long-standing debate among astrophysicists over the relationship between a galaxy’s size and its environment, but also raise new questions about how galaxies form and evolve over billions of years.
In a survey of 315 people conducted by researchers at the University of Washington and Georgetown University, respondents largely found creating and sharing sexually explicit “deepfakes” unacceptable. But far fewer respondents strongly opposed seeking out these media. Previous research has shown that other people viewing non-AI image-based abuse harms the victims significantly.
Two new studies introduce AI systems that use either video or photos to create simulations that can train robots to function in the real world. This could significantly lower the costs of training robots to function in complex settings.
After more than two decades with the University of Washington, Vice President Randy Hodgins announced today that he will step down from his role leading the UW Office of External Affairs and retire at the end of the 2024-2025 academic year. During his upcoming final year as Vice President, Hodgins said he will remain committed to advancing the University’s mission and ensuring a smooth transition.
New research from Ione Fine and Geoffrey Boynton, UW professors of psychology, shows Elon Musk’s projection for the latest Neuralink project rests on the flawed premise that implanting millions of tiny electrodes into the visual cortex, the region of the brain that processes information received from the eye, will result in high-resolution vision.
University of Washington researchers investigated how iBuyers — companies that use automated algorithms to quickly buy and sell homes — have affected the well-documented racial bias against Black home sellers. Looking at Mecklenburg County, North Carolina, they found that on average iBuyers paid more equal prices to Black and white home sellers than individual buyers, largely because iBuyers paid white sellers significantly less on average than an individual buyer. They also discovered that iBuyers were significantly more likely to resell homes to institutions, such as large rental companies that’ve been tied to high eviction rates and rent-gouging.
