Moo Deng. Pesto. Nibi. The three are a pygmy hippo, king penguin, and beaver, respectively, and they’re some of the latest celebrities to captivate the internet. David Barash, professor emeritus of psychology at the UW, is quoted.

Thousands of satellites in low-Earth orbit are still lighting up the sky, frustrating astronomers. Meredith Rawls, a research scientist of astronomy at the UW, is quoted.

Scientists at the UW have recreated the distinctive spiral shapes of shark intestines in 3D-printed pipes in order to study the unique fluid flow inside the spirals. Their prototypes kept fluids flowing in one preferred direction with no need for flaps to control that flow and performed significantly better than so-called "Tesla valves." The UW's Ido Levin, postdoctoral researcher in chemistry, and Alshakim Nelson, professor of chemistry, are quoted.

September 30, 12:00 – 1:20 pm | Psychology Edwards seminar talk with Alex L. White, Ph.D., Columbia University, Kindcaid Hall Can you recognize two...

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 â creating a prototype inspired by biology but with applications in engineering and medicine.

The Gordon and Betty Moore Foundation selected five aspiring inventors as the ninth cohort of Moore Inventor Fellows. This fellowship champions scientist-inventors who design groundbreaking tools and technologies — creative people poised to make substantial strides in scientific discovery, environmental conservation and patient care.

The UW-led study says the din from ships forces orcas to expend more time and energy hunting for fish. Jennifer Tennessen, senior research scientist at the UW Center for Ecosystem Sentinels, is quoted.

A new study comparing the brains of children before and after COVID-19 found that adolescent girls’ brains had aged faster than expected during the social isolation and lockdowns brought on by the pandemic. Patricia Kuhl, professor of speech and hearing sciences at the UW and co-director of the UW Institute for Learning and Brain Sciences, is quoted.

Volcanoes spewing carbon dioxide 250 million years ago heated the climate so much that extreme El Niño events became the norm, pushing most life on Earth past its limits. Peter Ward, professor of Earth and space sciences and of biology at the UW, is quoted.

When an orca hunts salmon, it clicks and buzzes. It sends a beam of sounds from its nasal passages into the murky depths in hopes that the sound waves will bounce back and reveal the location of its next nutritious meal. Those hopes are often dashed when noise from passing vessels drowns out orcas’ sonar signals. Jennifer Tennessen, senior research scientist at the UW Center for Ecosystem Sentinels, is quoted.

Ashleigh Theberge, associate professor of chemistry at the University of Washington, has been named to the Schmidt Sciences Polymath Program, entitling her to grants of up to $2.5 million over five years to "pursue risky, novel theories that would otherwise be difficult to fund," according to a Sept. 10 announcement from Schmidt Sciences. Theberge — one of six awardees this year — was selected from an applicant pool of 117, and is the first UW faculty member selected for the program, which is in its third year.

New research found that teens’ brains “aged” during the COVID-19 lockdowns due to the loss of social interaction. Girls were the most impacted. Patricia Kuhl, professor of speech and hearing sciences at the UW and co-director of the UW Institute for Learning and Brain Sciences, is quoted.

COVID lockdowns, such as school closures, canceled sports activities and stay-at-home orders, prematurely aged teen brains by as much as four years, researchers from the UW found. Patricia Kuhl, professor of speech and hearing sciences at the UW and co-director of the UW Institute for Learning and Brain Sciences, is quoted.

Neuroimaging found girls experienced cortical thinning far faster than boys did during the first year of COVID lockdowns. The UW's Neva Corrigan, research scientist at the Institute for Learning and Brain Sciences, and Patricia Kuhl, professor of speech and hearing sciences and co-director of the UW Institute for Learning and Brain Sciences, are quoted.

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 â from both large and small vessels â 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.
