Aliens might time their signals with a burst of supernova light. James Davenport, research assistant professor of astronomy at the UW, is mentioned.

In an experiment akin to stop-motion photography, an international team co-led by University of Washington scientists has isolated the energetic movement of an electron in a sample of liquid water â while âfreezingâ the motion of the much larger atom it orbits.

The research, involving primroses and hawk moths, suggests that air pollution could be interfering with plant reproduction. The UW's Jeff Riffell, professor of biology, and Joel Thornton, professor of atmospheric sciences, are quoted, and Jeremy Chan, a former graduate student, is pictured.

Americans are moving within the country far less often than they once did. The peak of U.S. migration followed the end of World War II and lasted through the mid-1970s. But while overall migration is down, state-to-state moves are slowly on the rise again. James Gregory, professor and associate chair of history at the UW, is quoted.

Byproducts of car exhaust disrupt pollination by degrading the floral scents that insects use to track down their favorite plants, according to new research. The UW's Jeff Riffell, professor of biology, and Joel Thornton, professor of atmospheric sciences, are quoted.

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.

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.

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.

Japan said its probe reached the moon after a year of setbacks to the nation’s space program, but it wasn’t immediately clear if the lander was intact or functioning. Saadia Pekkanen, professor of international studies 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.
