University of Washington researchers found, in historical whaling data, that longer baleen whale mothers were more likely to birth female calves than males. These results run contrary to a leading evolutionary theory that suggests that fit mothers will benefit more from male offspring.
Quantum dots, which are 10,000 times smaller than the width of a human hair, are unique materials that generate very specific colors of light. Researchers, including Brandi Cossairt, UW professor of chemistry, hope that quantum dots can one day be useful for more than just illuminating TV screens. UW News asked her to compare the quantum dots in QLED TVs with the ones her lab makes.
The James Webb Space Telescope has revealed new details in the core of the Butterfly Nebula, known to astronomers as NGC 6302. From the dense ring of dust that surrounds the nebula’s core to the tiny but bright star hidden within, the Webb observations paint a never-before-seen portrait of the nebula’s inner workings. Researchers at the UW and around the world are studying the imagery to learn more about the origins of cosmic dust and its role in the formation of planets like ours.
Dengue fever incidence could rise as much as 76% by 2050 due to climate warming across a large swath of Asia and the Americas, according to a new study.
Antarctic ice is melting at a startling pace, and the West Antarctic Ice Sheet is one of the greatest sources of uncertainty in climate projections. Researchers thought westerly winds were accelerating ice loss, but a new study from UW flips the narrative by 90 degrees, pointing instead to winds from the north.
Prochlorococcus, the most abundant photosynthesizing organism in the ocean, might be more vulnerable to climate change than researchers thought. Population decline could weaken the foundation of subtropical and tropical ecosystems as ocean temperatures continue to rise.
New findings call into question one of the core assumptions about teeth. Adult male spotted ratfish, a shark-like species native to the eastern Pacific Ocean, have rows of teeth on top of their heads, lining a cartilaginous appendage called the tenaculum, in addition to those in their jaws. They used their tenaculum teeth to grip females while mating in water.
Physicists have floated numerous theories to explain what dark matter might be, but to date, no experiment has turned up compelling evidence to support any of them. An international team of physicists, including researchers from the UW, is now working on a new kind of dark matter detector with the goal of capturing the first direct observation of the puzzling material. Results from the detector’s prototype have already ruled out one of the leading theories of how dark matter originated.
New research shows that deep-ocean oxygenation occurred 100 million years later than previously thought, aligning with the growth and spread of land plants. Once oxygenated, the ocean hosted rapid animal evolution, leading to the rise of modern vertebrates.
University of Washington researchers use AI to simulate the Earth’s current climate and interannual variability for up to 1,000 years. The model runs on a single processor and takes just 12 hours to generate a forecast.
A UW-led team of researchers used a fiber-optic cable to capture calving dynamics across the fjord of the Eqalorutsit Kangilliit Sermiat glacier in South Greenland. This allowed them to document — without getting too close — one of the key processes that is accelerating the rate of glacial mass loss and in turn, threatening the stability of ice sheets, with consequences for global ocean currents and local ecosystems.
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.
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.
