Explore recent research from the University of Washington: how sunbirds sip nectar through straw-like tongues, why the Seattle Fault might not pose as great a risk as previously thought, how to gauge landslide dam risk in the PNW, what marine microbes use for making meals and when the Simonyi Survey Telescope at the NSF-DOE Rubin Observatory will spot small inbound asteroids.

Come curious. Leave inspired. The UW offers an exciting lineup of in-person and online events. From thought-provoking art and music to conversations on culture, history, and science, the UW community invites you to explore, learn, and connect across disciplines throughout the University. 

A research team led by the UW has identified a new species of an ancient rodent-like creature. The new species, named Cimolodon desosai, was about the size of a golden hamster, the researchers said. It likely scampered on the ground and in the trees and ate fruits and insects.

UW News spoke with Paul Wiggins, a University of Washington associate professor of both physics and bioengineering, to learn about a surprisingly relatable behavior prompting bacteria to stockpile huge reserves of essential proteins.

A Nigerian scientist's "personal experience" with a wildfire, its threat to endangered bats she discovered just days before, and her campaign to protect them, has won her the global Goldman Environmental Prize. Iroro Tanshi, postdoctoral scholar of biology at the UW and recipient of the award, is quoted.

New research published in Current Biology reveals sunbirds use their long tongues as a kind of makeshift straw to hoover up nectar in flowersthe first vertebrates known to do so. Alejandro Rico-Guevara, associate professor of biology at the UW and curator of birds at the UW Burke Museum, is mentioned.

A new study doubles the evolutionary history of the weasel family. Researchers, including Chris Law, a UW principal research scientist in the biology department, have determined that a fossil that was discovered in Spain belongs to a new species dating back to around 6.5 million years ago. This new species was likely similar in size to the smallest living weasel species today, the least weasel.

The University of Washingtons graduate and professional degree programs again were recognized as among the best in the nation, according to U.S. News & World Reports 2026 Best Graduate Schools released late Monday.

A simple act like drinking nectar can hide an unexpected scientific story. Sunbirds, small and colorful birds found in many parts of the world, have surprised researchers with a completely new way of feeding. This discovery shows that even well-known animals can still teach us something new about nature. Scientists continue to study such behaviors to better understand how animals adapt and survive. UW research is mentioned.

A neural network based on a nematode worms connectome can puppeteer a digital fruit flys body, a new preprint shows. The work comes just two weeks after Eon Systems, a neurotechnology company based in San Francisco, announced that it had uploaded a fly brain and released a video of that brain controlling a biomechanical fly model in a virtual world. Bing Wen Brunton, professor of biology at the UW, and John Tuthill, professor of neurobiology and biophysics at the UW, are quoted.

The threat of rare, butdeadly diseaseis rising alongside mosquito populations in the Northwest. In response, scientists areresearchinghow mosquitoes detect a common compound in natural repellents. Jeff Riffell, professor of biology at the UW, is quoted.

New research at the University of Washington could help scientists develop better mosquito repellents as mosquito season grows longer in parts of the Northwest. Jeff Riffell, professor of biology at the UW, is quoted. This story was republished in numerous outlets.

A University of Washington-led team discovered that modern Nautilus and Allonautilus species inhabit deeper waters than their extinct ancestors did over 500 million years ago, with juveniles living at twice the depth of mature adults.

New research reports that sunbirds use suction from their tongue to sip nectar. The find is the first example of any vertebrate drinking through suction generated by the tongue alone, rather than by changing the shape of its mouth. A UW research project is mentioned.

Briana Abrahms, associate professor of biology at the University of Washington, studies how climate change affects human-wildlife interactions and increases conflict around the world. In January, she gave the keynote speech at the International Parliamentary Roundtable on Human-Wildlife Coexistence held in Botswana.
