You might not know it, but some moths can smell just as well as dogs. The nighttime insects use their antennae to sniff out flowers heavy with pollen up to a mile away. New research from the UW shows pollution in car exhaust can blunt the flowers’ scent – making it hard for pollinators to find the blossoms. The UW's Jeff Riffell, professor of biology, and Joel Thornton, professor of atmospheric sciences, are quoted.

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.

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.

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.

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.

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.

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.
