Air pollution is making it hard for some Washington state flowers to get pollinated, according to a new study in the journal Science. Jeff Riffell, professor of biology at the UW, is quoted.

An international team of scientists has blazed a new trail for studying how atoms respond to radiation, by tracking the energetic movement of electrons when a sample of liquid water is blasted with X-rays. Xiaosong Li, professor of chemistry at the UW, is quoted.

Scientists at this University of Washington facility in the San Juan Islands are working to help sunflower stars — a type of sea star — grow and thrive once again after their populations along the West Coast were devastated by a mysterious disease. Jason Hodin, research scientist in the UW Department of Biology, is quoted.

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.

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. 

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.

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.
