Mapping fungal relationships in trees

Korena Mafune received her PhD from UW’s School of Environmental and Forest Sciences, where she studied the root-associated fungal communities of old-growth bigleaf maple trees in Washington’s Queets and Hoh temperate rainforests. These trees accumulate layers of leaves and other organic matter on their canopy branches, which decay over time and produce a thick mat of organic soil high above the forest floor. Bigleaf maple trees have the capability to grow extensive adventitious rooting networks into these canopy soils which associate with fungal communities that thrive in the damp Pacific Northwest forests; some of these fungal associates attach to the roots and expand their fungal network outwards to aid the tree in taking up plant nutrients like nitrogen and phosphorus which the trees rooting system may not be able to reach on its own.


Modeling and predicting tree growth with data science

Stuart Ian Graham is a graduate student in the University of Washington’s Biology program who recently published a paper with Senior Data Science Fellow and eScience Institute Research Scientist Ariel Rokem, along with others from the University of Washington, Université de Montpellier, and University of California Los Angeles. The paper, published in the Forests journal and titled “Regularized Regression: A New Tool for Investigating and Predicting Tree Growth,” initially grew from a 2019 Winter Incubator project at eScience, which paired Graham and Rokem together to utilize data science to explore how neighboring tree species can influence one another’s growth rates in Mt. Rainier National Park in Washington State.


How UW Medicine is using cloud computing to aid Seattle's Covid response

Over the past year, the University of Washington and UW Medicine have been at the heart of the city of Seattle’s Covid-19 response: researchers studying social distancing and how the virus spreads on our communities, volunteers collecting and distributing supplies, clinical vaccine trials, and a partnership with the city to process over 2 million test samples at no cost to residents – all of which have helped Seattle maintain one of the lowest Covid-19 rates of major US cities. And with so many departments and teams working together, often involving clinical patient data, an adaptable and secure info-sharing system is absolutely necessary.


Help the Fibr algorithm learn to read MRI scans

The majority of mental health disorders are first diagnosed in childhood or adolescence. The disorders most commonly detected in young people include ADHD, anxiety, depression and behavior problems. Historically, individual labs and researchers interested in understanding the brain basis of mental health only had access to small amounts of data to analyze, like MRI scans, and for many procedures the data needed to be examined in detail by a professional. But as data science approaches have become more prevalent in neuroscience and other fields, researchers now have access to data collected from thousands of individuals. The sheer amount and complexity of these new datasets have made it difficult to scale up the historic approach.


Using data science to track marine heatwaves

Ocetrac tracking for oceanographic extremes

UW School of Oceanography Professor LuAnne Thompson and recent PhD graduate Hillary Scannell are leading a team that uses data science to track and predict marine heatwaves (MHW). These extreme hot-water events have had dramatic ecological impacts and have led to widespread toxic algal blooms, habitat degradation, and loss in commercially valuable fisheries. The ocean absorbs and stores the majority of excess heat in our climate; as the overall ocean temperatures have doubled over the past four decades, these heatwaves have grown more frequent and severe.


DiRAC astronomers on call: chasing gravity wave sources using APO

Researchers can now test general relativity in the strong-field regime using the gravitational-wave signals from merging black holes.

eScience scientists are using the latest data from the European Space Agency’s (ESA) Gaia Satellite to estimate the total mass of the galaxy.


What counts as terrorism? Racial heuristics and media portrayals of mass shooters

Researchers at the UW evaluate the conditions under which news media describe a violent event as terrorism and find that racial bias is evident in media coverage.


Combining citizen science and deep learning to amplify expertise in neuroimaging

The braindr web interface: braindr is hosted at Users may click pass or fail buttons, use arrow keys, or swipe on a touchscreen device to rate the image."

Researchers at the UW have developed Braindr, a web application for citizen scientists to inspect and annotate brain images by swiping left or right.


Nanoparticles could help us understand the relationship between structure and function in the brain

A team of UW researchers have recently begun to develop models that can integrate multiple types of data to better understand and predict structural and functional relationships in the brain.
