Zebrafish embryos aboard the Chinese Tiangong Space Station are the latest ‘aqua astronauts.’ Aaron van Loon, postdoctoral scholar of biology at the UW, is quoted.

Jeffrey Riffell, a University of Washington professor of biology, wants to understand how female mosquitoes find find a host to bite for a bloody meal. His research has shown that hungry mosquitoes find us by following a trail of scent cues, including chemicals exuded by our skin and sweat, as well as the carbon dioxide gas we exhale with each breath. Mosquitoes also like colors, at least certain ones. His team is closing in on how the sense of smell and vision work together to help a mosquito zero in for the final strike and get her blood meal.

And a new study offers a fuller understanding of tool use by sea otters. Otters in California's Monterey Bay use rocks and other objects to break open hard prey, letting them access certain larger prey and reducing their tooth damage. Chris Law, research scientist and teaching professor in biology at the UW, is quoted.

When sea otters face competition for their favorite kinds of food, some use tools — like rocks and even glass bottles — to open tougher prey. That’s according to a new study of sea otters in Monterey Bay, California. Chris Law, research scientist and teaching professor in biology at the UW, is interviewed.

Despite problems with humanity’s use of carbon-based fossil fuels, our whole existence is based on this element’s ability to create rich chemistry. Don Brownlee, professor of astronomy at the UW, is mentioned.

Often vilified by Hollywood as potential competitors and even threats to humans, both sea dwelling and fictional off world octopuses have made many a filmgoer squirm in horror. Aside from their piercing eyes, their brains and morphologies are as different from humans as any species could be. Peter Ward, professor of Earth and space sciences and of biology at the UW, is quoted.

Hummingbirds, I realized, are not just adorable. They're also jerks. Yes, jerks. But don't take my word for it. Alyssa Sargent, doctoral student of biology at the UW, is quoted.

There's a spot on the UW Bothell campus that is known for murders. Not the kind that elicit blood-curdling screams. The kind punctuated by caws and the flapping of thousands of wings, which may be equally terrifying — depending on your opinion of crows. Loma Pendergraft, lecturer of psychology at the UW, is quoted.

Despite the weather conditions, the courtyard of the UW Astronomy Department was busy with people trying to catch a glimpse of the partial eclipse. The Department of Astronomy hosted a viewing event with telescopes and eclipse glasses. The UW's Oliver Fraser, assistant teaching professor in astronomy, and Ruby Heidgerken, a student, are quoted.

Alejandro Rico-Guevara, assistant professor of biology at the UW and curator of ornithology at the UW Burke Museum, remembers when he first realized he was a hummingbird guy — not like an "I fill my hummingbird feeder every week" guy but an “I want to know everything about these birds” guy.

Certain chemicals break down a primrose’s key fragrance molecules, blunting its scent. The UW's Jeff Riffell, professor of biology, and Joel Thornton, professor of atmospheric sciences, are quoted.

Apparently humans aren't the only animals who are neat freaks. Find out how this small rodent and other animals also declutter. James Ha, emeritus research professor of psychology at the UW, is quoted.

Frank Herbert designed his beloved story, “Dune,” as a critique of our own world and a cautionary tale for the future. Herbert's time as a UW student is mentioned, and Jesse Oak Taylor, associate professor of English at the UW, is quoted.

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.
