Researchers model how ‘publication bias’ does — and doesn’t — affect the ‘canonization’ of facts in science
In an article published Dec. 20 in the journal eLife, researchers present a mathematical model that explores whether “publication bias” — the tendency of journals to publish mostly positive experimental results — influences how scientists canonize facts. Their results offer a warning that sharing positive results comes with the risk that a false claim could be canonized as fact. But their findings also offer hope by suggesting that simple changes to publication practices can minimize the risk of false canonization.

New study traces the marsupial origins in N. America, finds mammals during Age of Dinosaurs packed a powerful bite
A new study by paleontologists at the Burke Museum of Natural History & Culture and the University of Washington describes an early marsupial relative called Didelphodon vorax that lived alongside dinosaurs and had, pound-for-pound, the strongest bite force of any mammal ever recorded.
Answers to frequently asked questions about a 255-year-old tumor in a ‘pre-mammal.’
University of Washington paleontologists have discovered a benign tumor made up of miniature, tooth-like structures embedded in the jaw of an extinct ‘mammal-like’ gorgonopsian. Known as a compound odontoma, this type of tumor is common to mammals today. But this animal lived 255 million years ago, before mammals even existed.

Water conducts electricity, but the process by which this familiar fluid passes along positive charges has puzzled scientists for decades. But in a paper published in the Dec. 2 in issue of the journal Science, an international team of researchers has finally caught water in the act — showing how water molecules pass along excess charges and, in the process, conduct electricity.

UW Professor Emeritus David J. Thouless wins Nobel Prize in physics for exploring exotic states of matter
The Royal Swedish Academy of Sciences announced Tuesday that David James Thouless, professor emeritus at the University of Washington, will share the 2016 Nobel Prize in physics with two of his colleagues. Thouless splits the prize with Professor F. Duncan M. Haldane of Princeton University and Professor J. Michael Kosterlitz of Brown University “for theoretical discoveries of topological phase transitions and topological phases of matter,” according to the prize announcement from the Academy. Half the prize goes to Thouless while Haldane and Kosterlitz divide the remaining half. Thouless is the UW’s seventh Nobel laureate, and second in physics after Hans Dehmelt in 1989.

Researchers at the University of Washington have developed a novel toolkit based on modified yeast cells to tease out how plant genes and proteins respond to auxin, the most ubiquitous plant hormone. Their system, described in a paper published Sept. 19 in the Proceedings of the National Academy of Sciences, allowed them to decode auxin’s basic effects on the diverse family of genes that plants utilize to detect and interpret auxin-driven messages.

University of Washington biologist Dee Boersma and her colleagues combed through 28 years’ worth of data on Magellanic penguins to search for signs that natural selection — one of the main drivers of evolution — may be acting on certain penguin traits. As they report in a paper published Sept. 21 in The Auk: Ornithological Advances, selection is indeed at work on the penguins at the Punta Tombo breeding site in Argentina.

Many popular long-term drought estimates ignore the fact that plants will be less thirsty as carbon dioxide goes up. Plants’ lower water use could roughly halve some current estimates for the extent of future drought, especially in central Africa and temperate Asia.

Follow your nose: UW’s young corpse flower relocates to Volunteer Park Conservatory for fetid first bloom
Visitors to Seattle’s Volunteer Park Conservatory are in for a stinking treat, courtesy of the Department of Biology at the University of Washington. The conservatory has taken in a young corpse lily, affectionately known as Dougsley, which is set to blossom this week or next.
Paleontologists with the Burke Museum of Natural History and Culture and the UW have discovered a Tyrannosaurus rex, including a very complete skull. The find, which paleontologists estimate to be about 20 percent of the animal, includes vertebrae, ribs, hips and lower jaw bones.

University of Washington biologist Peter Ward’s body of research has helped policymakers recognize the impact nautiluses have on ocean ecosystems, as well as how they can — and cannot — replenish their numbers in the face of unrestricted, unregulated fishing. At a CITES meeting in September, Ward and his team hope nautiluses will get much-needed protections from trade and harvesting.

University of Washington professor Peter Kahn recently co-authored an opinion piece in the journal Science about the importance of interacting with nature in urban areas. UW Today asked Kahn a few more questions about the broader implications of his work.
The authors of a Science perspective piece discuss the growing tension between an arguably necessary role urban areas play in society and the numbing, even debilitating, aspects of cities that disconnect humans from the natural world.

Electrical energy fuels our modern lives, from the computer screen that keeps us up after sunset to the coffee maker that greets us at sunrise. But the electricity underlying our 21st century world, by and large, is generated at a cost — through the unsustainable expenditure of fossil fuels. For decades this demand for cheap,…

The malaria parasite can cause unusually severe cases of the eponymous disease in patients, leading to higher mortality and poorer health outcomes among survivors. But scientists have long struggled to understand why some patients develop severe malaria. The University of Washington’s International Center of Excellence for Malaria Research in South Asia — along with partners…

In traditional light-harvesting methods, energy from one photon only excites one electron or none depending on the absorber’s energy gap, transferring just a small portion of light energy into electricity. The remaining energy is lost as heat. But in a paper released May 13 in Science Advances, Wu, UW associate professor Xiaodong Xu and colleagues at four other institutions describe one promising approach to coax photons into stimulating multiple electrons. Their method exploits some surprising quantum-level interactions to give one photon multiple potential electron partners.

In the maelstrom of information, opinion and conjecture that is Twitter, the voice of truth and reason does occasionally prevail, according to a new study from UW researchers. Tweets from “official accounts” — the government agencies, emergency responders, media or companies at the center of a fast-moving story — can slow the spread of rumors on Twitter and correct misinformation that’s taken on a life of its own.
