An international team of paleontologists, led by researchers at the University of Washington and the Field Museum of Natural History, is identifying the animals that thrived in southern Pangea — the planet’s single supercontinent at the time — just before the so-called “Great Dying” wiped out about 70% of terrestrial species, and an even larger fraction of marine ones.
A UW-led project aimed to test the viability of seaweed as a soil amendment, and, if successful, develop a market for sea-based farmers to sell excess seaweed to their counterparts on land. The USDA froze the project’s funding, and for now, a solution remains just out of reach.
An international research effort, including scientists from the University of Washington, has finally revealed the cause of sea star wasting disease: a strain of the bacterium Vibrio pectenicida.
University of Washington researchers showed that they can monitor seismic activity at the ocean floor using fiber optic cables without disrupting telecommunications. They developed this technique in Alaska and then tested it off the coast of Oregon.
Kendall Valentine, an assistant professor of oceanography at University of Washington, along with collaborators from the University of Rhode Island and the Desert Research Institute are traveling to Anchorage and the Copper River Delta to study marshes that formed in the years following the 1964 earthquake.
Adrienne Fairhall and David Hertzog are among 120 new members and 30 international members elected “in recognition of their distinguished and continuing achievements in original research.”
New research found that a market-based approach to managing water could provide more reliable supplies for farmers, communities and industry. The right market design and a little extra investment could also help threatened fish species.
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.
A group of astronomers from across the globe, including a team from the University of Washington and led by Queen’s University Belfast, have revealed new research showing that millions of new solar system objects will be detected by a brand-new facility, which is expected to come online later this year.
A new University of Washington–led study projects that in the next 35 years increasing boreal fires will actually slow global warming by 12% globally and 38% in the Arctic. Because the aerosols in smoke reflect more sunlight and make clouds brighter, summer temperatures during fire season drop, leading to reduced sea ice loss and cooler winter temperatures.
On June 3, scientists working on the Muon g-2 experiment (pronounced “mew-on gee-minus-two”) released the third and final measurement of the muon magnetic anomaly. This result agrees with the published results from 2021 and 2023 but with a much better precision of 127 parts per billion, surpassing the original experimental design goal of 140 parts per billion.
The study revealed that iron released from industrial processes, such as coal combustion and steelmaking, is altering the ecosystem in the North Pacific Transition Zone, an area just north of Hawai’i that’s important for Pacific fisheries.
Children exposed to higher levels of ozone in their first two years of life were significantly more likely to be diagnosed with asthma or wheezing at ages 4-6 — but researchers didn’t observe the increased risk of asthma at ages 8-9.
Trickery by female white-necked jacobin hummingbirds results in reduced aggression from other hummingbirds and increased access to nectar resources.
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.
A recent theory proposes that whales weren’t just predators in the ocean environment: Nutrients that whales excreted may have provided a key fertilizer to these marine ecosystems. Research led by University of Washington oceanographers finds that whale excrement contains significant amounts of iron, a vital element that is often scarce in ocean ecosystems, and nontoxic forms of copper, another essential nutrient that in some forms can harm life.
Thousands of grasshopper specimens from mountains in Colorado show trends in how the insects changed in size over 65 years. With earlier emergence of spring greenery and earlier summer drought, grasshopper species that emerged early in the year grew larger, while grasshopper species that emerge later in the year grew smaller in size. The study, led by UW biologist Lauren Buckley, shows that changes in insect size can be predicted based on lifecycles and environmental conditions.
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.
Workers from small, rural communities often move into the outer edges of cities, which offer greater economic opportunities but often have low-quality housing that is likely to suffer greater damage during an earthquake. The risk grows even more when migrants come from low-income or tribal villages.
How fast the level of atmospheric carbon dioxide — and with it, the temperature — goes up matters for the ability of humans and ecosystems to adjust. A slower increase gives humans time to move away from low-lying coasts and animals time to move to new habitats. It turns out the rate of that increase matters for non-living systems, too. Camille Hankel, a postdoctoral researcher at the Cooperative Institute for Climate, Ocean and Ecosystem Studies, talks about her research on the Atlantic Ocean circulation.
The Hubble Space Telescope has generated the most comprehensive survey yet of the Andromeda galaxy, the nearest galactic neighbor to the Milky Way. The new mosaic of about 2.5 billion pixels yields new clues to the galaxy’s history. UW astronomers presented the findings Jan. 16 at a meeting of the American Astronomical Society.
University of Washington scientists recently discovered that the giant ‘conveyor belt’ currents that push star-forged material out of our galaxy and pull it back in can also transport carbon atoms. That means that a good deal of the carbon here on Earth, including the carbon in our bodies, likely left the galaxy at some point!
A research team at UW and the Pacific Northwest National Laboratory examined the atomic composition of enamel samples from two human teeth.
UW oceanographer Robert Morris and a collaborator at UCLA are going out with students to collect the most abundant bacteria in the oceans to understand how its relationship with marine viruses changes depending on the place or the season. They leave Dec. 16 aboard UW School of Oceanography’s small research vessel, the RV Rachel Carson.
Since 2018 the Zwicky Transient Facility, an international astronomical collaboration based at the Palomar Observatory in California, has scanned the entire sky every two to three nights. As part of this mission, the ZTF’s Bright Transient Survey has been counting and cataloguing supernovae — flashes of light in the sky that are the telltale signs of stars dying in spectacular explosions. On Dec. 4, ZTF researchers — including astronomers at the University of Washington — announced that that they have identified more than 10,000 of these stellar events, the largest number ever identified by an astronomical survey.
University of Washington researchers show that the all-time record low in winter sea ice extent in 2023 can be explained by warm Southern Ocean conditions and patterns in the winds that circled Antarctica months earlier, allowing forecasts for sea ice coverage around the South Pole to be generated six or more months in advance. This could support regional and global weather and climate models.
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.
From a base at the southwest corner of the UW’s Seattle campus, the Office of the Washington State Climatologist’s Guillaume Mauger and Karin Bumbaco provide expertise, tools and resources on “all things climate” to partners and communities across the state.
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.
Jie Xiao, University of Washington professor of mechanical engineering, talks about batteries and how academia can help support the growing domestic battery manufacturing industry.
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.
NASA has awarded a five-year, $2.5 million grant to establish a regional scientific consortium based at the University of Washington, in partnership with Washington State University and the Pacific Northwest National Laboratory. The consortium will use an interdisciplinary approach to explore how the space environment — both in low-Earth orbit and beyond — affects living things.
Chelsea Wood, a University of Washington associate professor of aquatic and fishery sciences, has an upcoming children’s book titled “Power to the Parasites! Everything You (N)ever Wanted to Know About the Creepy Crawlies Hidden in Your Home, Your Food, Your Pets – and Maybe Even in You!” The book introduces kids to the world of parasitism.
A new study finds that rocky planets orbiting small stars do have the potential for stable, life-supporting atmospheres. The finding supports continued study of the TRAPPIST-1 system and other top candidates in the search for life outside our solar system.
Polar bears in some parts of the high Arctic are developing ice buildup and related injuries to their feet. The changes appear to be an unexpected consequence of climate change, related to changing conditions in a warming Arctic.
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.
UW researchers collaborated with people at multiple institutions to collect pre-storm data and place sensors to measure storm surge levels and wave height during Hurricane Helene’s landfall.
