Many animals rely on scent to make sense of the world. Pollution from smokestacks and tailpipes may be making them nose-blind. The UW's Jeff Riffell, professor of biology, and Joel Thornton, professor of atmospheric sciences, are quoted.

Scientists at the University of Washington have discovered that nighttime air pollution â coming primarily from car exhaust and power plant emissions â is responsible for a major drop in nighttime pollinator activity. Nitrate radicals (NO3) in the air degrade the scent chemicals released by a common wildflower, drastically reducing the scent-based cues that its chief pollinators rely on to locate the flower. The findings, published Feb. 9 in Science, are the first to show how nighttime pollution creates a chain of chemical reactions that degrades scent cues, leaving flowers undetectable by smell. The researchers also determined that pollution likely has worldwide impacts on pollination.

The impact of digital technology on teens' mental health is the focus of a new course developed by Lucia Magis-Weinberg in the UW Department of Psychology.

Ashleigh Theberge's UW lab creates bioanalytical chemistry tools. Some are transforming how clinical studies can be conducted. 

Integer linear programming can help find the answer to a variety of real-world problems. Now researchers have found a much faster way to do it. Research from Thomas Rothvoss, Professor of Mathematics, is mentioned.

A year into Seattle Public Schools' lawsuit against social media companies, the case is gaining traction. More than 50 school districts in Washington state — and dozens more across the country — have joined Seattle’s lawsuit. Lucía Magis-Weinberg, assistant professor of psychology at the UW, is quoted.

Dogs share so much of their lives with humans and can develop the same health conditions we do, like dementia or diabetes. Those similarities drove researchers to wonder if our medical science can help dogs live longer — and if maybe, our furry friends could tell us something about how we age, too. Daniel Promislow, professor of biology and of laboratory medicine and pathology at the UW, is quoted.

At the the 2024 annual meeting of the Society for Integrative and Comparative Biology in Seattle, researchers discussed the increased use of artificial intelligence and machine learning for learning about things like spiders, bats, bees, elephants and other creatures. Jeff Riffell, a professor of biology at the UW, is quoted.

The National Institute on Aging may let funding lapse for a yearslong study of nearly 50,000 pet dogs, which could also offer insight into human health. Daniel Promislow, professor of biology and of laboratory medicine and pathology at the UW, is quoted.

Alejandro Rico-Guevara, assistant professor of biology at the UW and curator of ornithology at the UW Burke Museum, has dedicated his life to looking at hummingbirds in ways other people can’t. What he’s learned changed the world’s understanding of hummingbirds and, at times, has been of great use to humans.

Starting in 2025, the Vera C. Rubin observatory will increase the number of known objects circling the sun by roughly tenfold, spotting new comets, exotic asteroids from other stars, and perhaps even the elusive Planet Nine. The UW's Mario Jurić, professor of astronomy, and Pedro Bernardinelli, postdoctoral fellow in astronomy, are quoted.

Organizers hope to save long-running project on canine aging and longevity. Daniel Promislow, professor of biology and of laboratory medicine and pathology at the UW, is quoted.

A proposal to build a far-flung set of radio antennas to measure the cosmos is one of 13 far-out concepts to receive seed funding from the NASA Innovative Advanced Concepts program, also known as NIAC. Matthew McQuinn, associate professor of astronomy at the UW, is quoted.

Lisa Dabek (PhD, Psychology, 1994), senior conservation scientist at the Woodland Park Zoo, studies and protects tree kangaroos in the cloud forests of Papua New Guinea. 

"For some people, social media is inconsequential — a cat photo here, a banana slip TikTok there. For others, it’s all-consuming — a helpless catapult into a slurry of anxiety, self-harm and depression...But social media use also differs by race and ethnicity — and there’s far less discussion of that," writes columnist Pamela Paul. Lucía Magis-Weinberg, assistant professor of psychology at the UW, is quoted.
