An unappreciated aspect of chemical reactions on the surface of metal oxides could be key in developing more efficient energy systems, including more productive solar cells or hydrogen fuel cells efficient enough for automobiles.
Not having enough Chinook salmon to eat stresses out southern resident killer whales more than having boatloads of whale watchers nearby, according to hormone levels of whales summering in the Salish Sea. In lean times, however, the stress normally associated with boats becomes more pronounced, further underscoring the importance of having enough prey.
In a study published this week in Nature Climate Change, University of Washington and European scientists project that in the next 50 years global climate change will disrupt power generation in the U.S. and Europe. Warmer water and lower flows are predicted to interrupt the supply of cooling water.

Scientists try to find which single-letter switches in the genetic code influence health risks.
A safe haven could be out of reach for 9 percent of the Western Hemisphere’s mammals, and as much as 40 percent in certain regions, because the animals just won’t move swiftly enough to outpace climate change, according to new research from the UW School of Environmental and Forest Sciences.
A textured surface mimics a lotus leaf to move drops of liquid in particular directions. The low-cost system could be used in portable medical or environmental tests.
UW researchers have discovered a problem with a climate record that is often cited by climate change skeptics.
Changes in the speed that ice travels in more than 200 outlet glaciers indicates that Greenland’s contribution to rising sea level in the 21st century might be significantly less than the upper limits some scientists thought possible, a new study shows.
Big trees three or more feet in diameter accounted for nearly half the biomass measured at a Yosemite National Park site, yet represented only 1 percent of the trees growing there.
The cells that line the pipes leading to the heart pull more tightly together in areas of fast-flowing blood. The cells’ mechanical response to their environment could aid understanding of heart disease.
Decades of research into how much plastic litters the ocean, conducted by skimming only the surface, may in some cases vastly underestimate the true amount of plastic debris in the oceans, according to a University of Washington oceanographer publishing in the journal Geophysical Research Letters.
Electrical engineering professor John Sahr gives his read on the increase in solar activity, and how it relates to his research.
A magnetized ion plasma system devised by a UW researcher to propel spacecraft at ultra-high speeds could be adapted to clean up dead satellites and other debris crowded in Earth orbit.
Head for Paws-On Science: Husky Weekend, March 30, 31 and April 1, at Pacific Science Center, for 50 stations featuring UW research. UW faculty, staff, students and their families receive a 20 percent discount on admission during the event, as do UW alums.
Evidence from fossilized raindrop impressions from 2.7 billion years ago indicates that an abundance of greenhouse gases most likely caused the warm temperatures on ancient Earth.
Researchers have devised a nanoscale sensor to electronically read the sequence of a single DNA molecule, a technique that is fast and inexpensive and could make DNA sequencing widely available.
An odd, previously unseen landform could provide a window into the geological history of Mars, according to new research by University of Washington geologists.
A new online portal and smartphone app lets Washington and Oregon residents enter the addresses of their homes, schools, workplaces or kids’ day care centers to check if they’re in harm’s way should a tsunami hit. The tool, being publicized on the heels of the one-year anniversary of the Tohoku tsunami, was developed by researchers at the Applied Physics Laboratory.
Cherry trees in full bloom in our nation’s capital could be as much as four weeks earlier by 2080 depending on how much warming occurs. So says an analysis conducted at the University of Washington that relied on the UW’s own cherry trees as one test of a computer model used in the project.
New research shows that at least one group of small mammals, the multituberculates, actually flourished in the last 20 million years of dinosaurs reign and survived their extinction.
Greenroads, a rating system developed at the University of Washington to promote sustainable roadway construction, awarded its first official certification to a Bellingham project that incorporates porcelain from recycled toilets.
On the one-year anniversary of Japan’s great Tohoku earthquake and tsunami, UW scientists said the devastating event has some important lessons for the Pacific Northwest – most notably, that a similar event will happen here, and this region is much less prepared than Japan.
From Seattle to Japan, University of Washington faculty had an important role in providing information about the aftermath of the March 2011 Japan earthquake and tsunami.
Over the next three years, a team of UW students will convert a 2013 Chevy Malibu into a fuel-efficient, low-emissions vehicle that still meets consumer demands for a driver-friendly car. The UW is one of 15 schools participating in the EcoCAR 2 contest, sponsored by General Motors and the U.S. Department of Energy.
Learn about polar bears and penguins. Center a two-foot tusk on your forehead and imagine youre a narwhal exploring your icy-ocean home. For these activities and more, grab the kids and head for Polar Science Weekend, March 1 to 4, sponsored by the UW’s Applied Physics Laboratory and Pacific Science Center.
The plight of the tiger – none of the worlds 350 protected areas in the tigers range is large enough to support a viable population – is the subject of the UWs “Sustaining our World” lecture March 1. Eric Dinerstein, the World Wildlife Funds chief scientist and a UW alum, will speak on “All Together Now: Linking Ecosystem Services, Endangered Species Conservation and Local Livelihoods” at 6 p.m., in Kane 220.
