Researchers have made startling discoveries in recent years about a crow’s ability to communicate, solve problems, remember people and use tools. What researchers are discovering about crow brains is changing how scientists understand intelligence — and bringing into question our accepted version of evolution. John Marzluff, professor of environmental and forest sciences at the UW, Loma Pendergraft, lecturer of psychology at the UW, and Doug Wacker, assistant professor of biological sciences at UW Bothell, are quoted.

Five years after Amazon committed to an ambitious climate goal, the company says it is making progress on reducing emissions — but critics allege those calculations are misleading. Aseem Prakash, professor of political science at the UW, is quoted.

Aboriginal artifacts in Australia that were likely used for ritual spells may be evidence of the oldest culturally transmitted ritual on record. Ben Marwick, professor of anthropology at the UW, is quoted.

Beginning next year, the Vera C. Rubin Observatory will use the world’s largest digital camera to give us a whole new view of the universe. Mario Jurić, professor of astronomy at the UW, is quoted.

As the weather starts heating up this week, you may be tempted to go outside—but with the outdoors comes the possibility of getting bitten by mosquitoes. And if you find yourself getting a lot of mosquito bites, it could be because of the way you smell or the colors of the clothes you are wearing, recent research has found. The UW's Jeff Riffell, professor of biology, and Melissa Leon Norena, a doctoral student of biology, are quoted.

Dr. Abigail Swann, a UW professor of atmospheric sciences and of biology, led a project that combined climate projections with plant models to determine what combination of traits might be best adapted to future climates. The study used projections of weather and climate across the U.S. in 2050 and 2100 with a model that simulates corn’s growth to find the mix of traits that will produce the highest, most reliable yield under future conditions across the country.

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.

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.

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.
