At the turn of the century, 3.8 million people banded together in a real-time search for aliens — with screensavers. The project was called SETI@home. The hope was that with the power of millions of computers, researchers could comb through radio signals hitting Earth from outer space to find a hint of something unusual. James Davenport, research assistant professor of astronomy at the UW, is interviewed.

The Hubble Space Telescope has generated the most comprehensive survey yet of the Andromeda galaxy, the nearest galactic neighbor to the Milky Way. The new mosaic of about 2.5 billion pixels yields new clues to the galaxy's history. UW astronomers presented the findings Jan. 16 at a meeting of the American Astronomical Society.

Giant ships that transport everything from coffee cups to clothes across the ocean are often so large they can’t tell when they collide with a whale. Now, research out of the Northwest could help these massive vessels avoid collisions with whales around the world. Anna Nisi, a postdoctoral scholar of biology at the UW, is quoted.

The carbon that is a key component of the human body — and all other lifeforms on Earth — may have traveled outside the galaxy after being created before returning on a cosmic "conveyor belt," an author of a new study has suggested. Samantha Garza, a doctoral student of astronomy at the UW, is quoted.

The southern resident killer whale, known as Tahlequah, has now lost another calf in what the Center for Whale Research called “devastating” news. Samuel Wasser, professor of biology at the UW, is quoted.

University of Washington scientists recently discovered that the giant 'conveyor belt' currents that push star-forged material out of our galaxy and pull it back in can also transport carbon atoms. That means that a good deal of the carbon here on Earth, including the carbon in our bodies, likely left the galaxy at some point!

Most shipping routes cross whale habitats worldwide. Briana Abrahms, assistant professor of biology at the UW, is quoted.

For the past decade or so, Aseem Prakash, professor of political science at the UW, has been teaching a course on climate politics in the UW’s political science department. During that time, there have been three climate change initiatives on the ballot here. He’s had a front row seat for how policymakers, activists and campaigners have sought to frame and spin one of the toughest issues in politics.

According to a study by the UW, hummingbirds move their bills and tongues very quickly to drink a flower's nectar. Alejandro Rico-Guevara, assistant professor of biology at the UW and curator of birds at the UW Burke Museum, is quoted.

Whether it’s smartphones or sneakers, toys or tents, about 80% of commercial goods are transported to markets around the world using giant container ships. As global shipping routes grow to meet increasing demand, so too does the likelihood of fatal collisions with whale species whose ranges overlap with them. Anna Nisi, a postdoctoral scholar of biology at the UW, is interviewed.

With the near complete end of commercial whaling, ship collisions are now a leading cause of death worldwide for large whale species, according to new research published in Science. Yet little is done to manage this risk. Anna Nisi, a postdoctoral scholar of biology at the UW, is quoted.

Hummingbirds, among the smallest birds on the planet, flap their wings at as much as 80 beats a second. And scientists have been studying how they get enough nectar to satisfy that energy demand. Alejandro Rico-Guevara, assistant professor of biology at the UW and curator of birds at the UW Burke Museum, is quoted.

At first glance, hummingbird bills look like straws — long and thin, perfect for sipping nectar. But a new study reveals that this comparison is far from accurate. Alejandro Rico-Guevara, assistant professor of biology at the UW and curator of birds at the UW Burke Museum, is quoted.

Hummingbird bills — their long, thin beaks — look a little like drinking straws. But new research shows just how little water, or nectar, that comparison holds. University of Washington scientists have discovered that the hummingbird bill is surprisingly flexible.

"Climate policy should not become associated with halted mobility, dark and cold buildings, and spoiled food in refrigerators. An important collective (as opposed to household) level response to outages is to strengthen grid resilience via undergrounding power lines," write the UW's Nives Dolšak, professor of marine and environmental affairs, and Aseem Prakash, professor of political science.
