Mon, 04/04/2016 | UW TodayThe Twittersphere does listen to the voice of reason — sometimes
HCDE's emCOMP lab has found that tweets from "official accounts" can slow the spread of rumors on Twitter and correct misinformation that’s taken on a life of its own. "Avoiding social media channels because you don't want to be confronted with misinformation is a real danger for an organization. You're essentially opening up a space for information to be spreading without your voice being a part of it." – Kate Starbird, UW assistant professor of human-centered design and engineering

Mon, 02/29/2016 | UW TodayDoctor, patient expectations differ on fitness and lifestyle tracking
HCDE researchers found doctors lack the tools and capacity to interpret a deluge of fitness, food and lifestyle data that patients are self-tracking. In a study that won a best paper award and will be presented at the ACM conference on Computer-Supported Cooperative Work and Social Computing, the UW team surveyed 211 patients and interviewed 21 doctors, dietitians and other health care providers about their expectations for how patients' self-tracking data should be shared and used.
"We've heard doctors say more and more that people bring this data into the clinic and they’re just overwhelmed by it," said lead author Christina Chung, a UW doctoral student in Human Centered Design & Engineering. The team, which includes UW physicians, computer scientists and engineers, is exploring ways to make self-tracking data more clinically useful and to help health care providers and patients collaboratively engage with it.
Mon, 02/29/2016 | UW TodayNASA data used to track groundwater in Pakistan
UW civil and environmental engineers helped Pakistani water managers access free NASA satellite data to monitor groundwater changes in Pakistan's vast farmland areas, where setting up a traditional monitoring network had taken nearly eight years in one province alone.
"Satellites up in space looking at how much water we have underground, in rivers or in the atmosphere are providing routine observations that can help policymakers and on-the-ground managers make informed decisions," said Faisal Hossain, UW associate professor of civil and environmental engineering. "From offering improved flood forecasting to indicating areas where groundwater resources are threatened, freely available satellite data can be an invaluable resource, particularly in developing countries." Hossain runs the UW Sustainability, Satellites, Water and Environment Research Group.
Thu, 02/25/2016 | UW TodayDriverless cars could increase reliance on roads
A CEE study predicts a 5 to 60 percent increase in car energy consumption due to people choosing to use highly automated cars in cases where they would have previously taken trains or planes.
“There is a lot of hype around self-driving cars, much of it somewhat utopian in nature. But there are likely to be positives and negatives,” said Don MacKenzie, a UW assistant professor of civil and environmental engineering who co-authored the study. “By taking a clear-eyed view, we can design and implement policies to maximize the benefits and minimize the downsides of automated vehicles.”
Wed, 02/24/2016 | UW TodayClean, efficient cookstoves from UW-industry partnership to be manufactured in Kenya
An efficient and clean wood-burning cookstove developed by a local non-profit lab in close collaboration with UW mechanical engineers will reduce the amount of fuel rural families in the developing world need to collect or buy and reduce exposure to harmful particulate pollution produced by traditional cooking flames.
The new wood-burning cookstove will be manufactured in BURN Manufacturing’s factory in Nairobi, Kenya beginning this summer and sold across East Africa. “If women have to collect twice as much wood to cook their food, then they’re spending less time raising themselves out of poverty,” said Jonathan Posner, UW associate professor of mechanical engineering and principal investigator of the Department of Energy-funded Clean Cookstove Lab at the UW.

Fri, 02/05/2016 | UW Today‘On-ramping’ paves the way for women scientists, engineers to return to academia
To widen the pool of women faculty in STEM, UW researchers and leaders have explored strategies to encourage women scientists and engineers with industry or government experience to transition into academia. Ten women who participated in the UW's On-Ramps into Academia workshops and made the leap were interviewed about the challenges and rewards and also the support that made it easier. Initial concerns included having spent more time developing products than publishing papers, not being able to discuss their work because of intellectual property concerns, or having been outnumbered by men when they were getting their doctorate degrees. Ultimately, though, the women found other dimensions of an academic career attractive enough to want to return.
Authors of a paper recently published in the Journal of Technology Transfer are Eve Riskin, a professor in EE and associate dean for diversity and access at the UW College of Engineering and UW iSchool Ph.D. student Katie O’Leary, ADVANCE director Joyce Yen, and professor of bioengineering Matt O’Donnell.
Mon, 01/25/2016 | UW TodayNew handheld, pen-sized microscope could ID cancer cells in doctor’s offices and operating rooms
ME researchers are developing a handheld microscope to help differentiate healthy and cancerous cells in an office setting or operating room. "Being able to zoom and see at the cellular level during the surgery would really help them to accurately differentiate between tumor and normal tissues and improve patient outcomes," said ME Assistant Professor Jonathan Liu. The handheld microscope, roughly the size of a pen, combines technologies in a novel way to deliver high-quality images at faster speeds than existing devices. Researchers expect to begin testing it as a cancer-screening tool in clinical settings next year.

Fri, 01/15/2016 | UW TodayStir no more: UW scientists show that draining speeds up bioassays
BioE researchers have shortened the wait time in detecting cellular proteins and DNA. Inspired by studies of fluid dynamics, Xiaohu Gao's team worked around the commonly used and sometimes days-long staining process in which detector molecules bind to their targets to produce a visible color change. Instead of waiting for detector molecules to drift through solution to a target at the bottom, Gao's team allowed detector molecules close to the surface to bind. Then they drained the solution from the plate, mixed it, put it back, and repeated this cycle dozens of times — which they call 'cyclic solution draining and replenishing' and resembles a washing machine's function.
Tue, 01/12/2016 | UW TodayUW computer scientists to make financial products better and more available for the poor
