It took 100 million years for oxygen levels in the oceans and atmosphere to increase to the level that allowed the explosion of animal life on Earth about 600 million years ago, according to a study co-authored by two University of Washington scientists and led by the University College London.
When an earthquake struck Nepal in late April 2015, thousands of lives were lost in the initial disaster. But it was hard to assess the scale of the damage to rural areas, and still lurking were threats from unstable slopes and dammed glacier-fed lakes that could dislodge at any time to flood villages below. A University of Washington Tacoma faculty member was part of an international team of scientists who worked with government agencies and private companies on a massive…
A new University of Washington study confirms that composting food scraps is better than throwing them away, and also calculates the environmental benefits associated with keeping these organic materials out of landfills.
On Dec. 3, the legislature for Argentina’s Chubut province established a new marine protected area off Punta Tombo, which would help preserve the feeding grounds for about 500,000 Magellanic penguins that make their home along this rocky stretch of Argentine coast. This is welcome news for the UW scientists who have studied these penguins for decades and advocated for their conservation.
A University of Washington graduate student saw green-starved Ballard as an opportunity to call attention to areas in the neighborhood that have restoration potential. Her new report, the “Ballard Green Spaces Project,” identifies 55 sites that could be restored as natural areas for people and wildlife, increasing the neighborhood’s total amount of accessible green spaces.
Two University of Washington researchers have uncovered details of the radically divergent strategies that two common tree species employ to cope with drought in southwestern Colorado. As they report in a new paper in the journal Global Change Biology, one tree species shuts down production and conserves water, while the other alters its physiology to continue growing and using water.
The long, slow 2014 eruption of Iceland’s Bardarbunga volcano offers a testbed to show how sulfur emissions, from volcanoes or humans, act to brighten clouds and reflect more sunlight.
A citizen science project that asks volunteers to transcribe historic ships’ logbooks to uncover data about past Arctic climate has added logbooks from hundreds of whaling ships. The hunters’ handwritten logs will provide new clues about the history of Arctic climate and sea ice.
The speed of vessels operating near endangered killer whales in Washington is the most influential factor – more so than vessel size – in how much noise from the boats reaches the whales, according to a new study published today in the online journal PLOS ONE.
Four University of Washington researchers are among 347 new fellows of the American Association for the Advancement of Science for 2015.
Neutrinos may be small, but when it comes to prizes, they pack quite a punch. In October, it was announced that two scientists who headed international projects to study these miniscule, seemingly ephemeral subatomic particles will share the Nobel Prize in Physics. On Nov. 8, these same scientists joined five of their colleagues from other neutrino projects to accept the 2016 Breakthrough Prize in Physics. The $3 million prize will be shared among the over 1,300 scientists, including University of…
University of Washington scientists have sequenced the complete genetic makeup of a species of ecologically important algae, which may aid in biofuel production.
A new report by the University of Washington synthesizes all the relevant research about the future of the Puget Sound region to paint a picture of what to expect in the coming decades, and how to prepare.
Since the first laser was invented in 1960, they’ve always given off heat. University of Washington researchers are the first to solve a decades-old puzzle — figuring out how to make a laser refrigerate water and other liquids.
Paleontologists with the University of Washington’s Burke Museum of Natural History and Culture find that tiny organisms called foraminifera have a big story to tell about the health of Puget Sound. Two recent studies about the health of Bellingham Bay and inlets in the Bremerton area found the diversity and number of foraminifera — single-celled marine organisms that live on the sea floor — deteriorated significantly. The decline of these microscopic organisms is consistent with the deterioration of snails and other larger marine animals, even though analysis showed a reduction of chemical pollutants in Bellingham Bay and Bremerton over the same period of time.
When President Barack Obama visited the shrinking Exit Glacier in September, he pointed to a very obvious sign of our warming planet literally at his feet. Less visible, but perhaps more indelible, signs of changing climate lie in the oceans. A University of Washington researcher argues in the journal Science that people — including world leaders who will gather later this month in Paris for global climate change negotiations — should pay more attention to how climate change’s impacts on…
A new book by University of Washington geologist David Montgomery weaves history, science and personal challenges into an exploration of humanity’s tangled relationship with microbes, perhaps the least loved and most misunderstood creatures on Earth — and in you. “The Hidden Half of Nature: The Microbial Roots of Life and Health” comes out Nov. 16 from W.W. Norton & Co. Montgomery, a UW professor of Earth and space sciences, co-wrote the book with his wife, Anne Biklé, a biologist and…
An atmospheric haze around a faraway planet — like the one which probably shrouded and cooled the young Earth — could show that the world is potentially habitable, or even be a sign of life itself.
With high-tech weather radars, weather balloons, ground instruments and NASA’s DC-8 flying laboratory, scientists will be watching rain and snow storms on Washington’s famously wet Olympic Peninsula.
Two University of Washington faculty members have been awarded a grant from The Swartz Foundation to support research in theoretical neuroscience. The award establishes the UW as the latest of the Swartz Foundation-supported centers for innovation in this growing field, which spans mathematics, statistics, physics and biology. “This award is a recognition of what is happening here at the UW in theoretical neuroscience research,” said Adrienne Fairhall, a UW associate professor in the Department of Physiology and Biophysics. “It is…
A report from the interdisciplinary UW Tech Policy Lab on the challenges of augmented reality suggests such systems should be adaptable to change, resistant to hacking and responsive to the needs of diverse users.
By age 5 children have a sense of self-esteem comparable in strength to that of adults, according to a new study by University of Washington researchers.
In science, decades can pass between a proposed theory and its real-world application. That is precisely what University of Washington mathematics professor Gunther Uhlmann was expecting when he and three colleagues proposed a means to develop an electromagnetic wormhole in a 2007 paper in Physical Review Letters. Their theoretical wormhole — an invisible tube for electromagnetic fields — would cloak an electromagnetic field while it passed through the tube, creating a “secret” connection between the entry and exit point. Uhlmann…
A nearby exoplanet has an atmosphere that might be similar to Earth’s before life evolved. In an attempt to simulate the structure of this exoplanet’s atmosphere, UW researchers became the first to simulate three-dimensional exotic clouds on another world.
A new study in Ecology shows that Alaskan Dolly Varden trout, once they reach about 12 inches in length, can retire permanently from going to sea. They rely on digestive organs that can massively expand and contract and a unique relationship with sockeye salmon.
By more accurately predicting how variations in DNA sequences affect gene splicing, a new UW model and publicly available Web tool can help narrow down which genetic mutations cause disease and which have little effect on a person’s health.
The equipment used to farm geoducks, including PVC pipes and nets, might have a greater impact on the Puget Sound food web than the addition of the clams themselves. That’s one of the findings of the first major scientific study to examine the broad, long-term ecosystem effects of geoduck aquaculture in Puget Sound.
A UW graduate student’s research paper is the first serious study of whether climate change is likely to cause human migration to the Puget Sound region.
A Nov. 7 concert in Seattle’s Benaroya Hall promises to offer the audience a decidedly stellar musical experience. The event, “Origins: Life and the Universe,” will pair live performances of new compositions with video and slideshow scenes depicting cosmic events like the Big Bang, as well as scenes from distant worlds and Earth’s own life-filled history. The Northwest Sinfonia, under the direction of Grammy Award-winning conductor David Sabee, will perform the eight works by Pacific Northwest composers while the projected…
The David and Lucile Packard Foundation has named the University of Washington’s Brandi Cossairt, an assistant professor in the Department of Chemistry, as one of 18 Packard Fellows for 2015.
In a study published this week in the journal PLOS ONE, researchers have used new high-performance computing methods and comprehensive data on the distribution of thousands of species to map the threat that climate change poses to birds, mammals and amphibians across the Western Hemisphere. They found that although Arctic areas have experienced the most rapid warming to date, climate-related threats to the Amazon basin’s biodiversity will eclipse those in other regions by the year 2100.
The location of bubble plumes off the Pacific Northwest coast supports the idea that gradual ocean warming at about a third of a mile depth may be releasing frozen methane in the seafloor, causing it to bubble up as a gas.
At 2:45 a.m. on Oct. 6, bleary-eyed Nobel Prize enthusiasts on the West Coast were treated to an unexpected lesson about fundamental particles and forces in our universe. Across the globe in Stockholm, a panel of scientists announced that the 2015 Nobel Prize in Physics would honor two scientists who led international collaborations to understand mysterious particles called neutrinos. The prize recipients, Takaaki Kajita and Arthur McDonald, respectively led the Super-Kamiokande Collaboration in Japan and the Sudbury Neutrino Observatory Collaboration…
A group of young marine-disease researchers from around the country has contributed key information about sea stars’ immune response when infected with a virus that is thought to cause a deadly wasting disease. It’s the first time researchers have tracked how genes behave when encountering this naturally occurring pathogen, which could help explain how sea stars attempt to fight the virus and why they develop lesions and appear to melt.
Alfred Nobel is remembered for the annual prizes given in his name. But were it not for his confused but effective will, we might remember him as the inventor of dynamite, who grew rich inventing and developing lethal explosives.
Astronomers with the University of Washington’s Virtual Planetary Laboratory have created the “habitility index for transiting planets” to rank exoplanets to help prioritize which warrant close inspection in the search for life beyond Earth.
The first simulation of the individual crystals in volcanic mush, a mix of liquid magma and solid crystals, shows the mixing to help understand pressure buildup deep inside a volcano.
A new report published Tuesday documents all of the fishes that live in the Salish Sea. In total, 253 fish species have been recorded, and that’s about 14 percent more than in the last count.
Earth-like planets orbiting close to small stars probably have magnetic fields that protect them from stellar radiation and help maintain surface conditions that could be conducive to life, according to research by UW astronomers.
