(Press-News.org) The West’s electrical grid is a 136,000-mile patchwork of transmission lines connecting two Canadian provinces, 11 Western states and pieces of three others, serving 80 million people.
While it drives a vital and growing piece of the U.S. economy, this fragile network remains vulnerable to increasingly extreme weather and wildfire risks, according to Masood Parvania, an associate professor of electrical and computing engineering at the University of Utah’s John and Marcia Price College of Engineering.
“These extreme weather events are not the way they used to be in the past. They are more frequent, so we get more of them, and they are more intense” said Parvania, who will co-lead the newly established U.S.-Canada Center on Climate-Resilient Western Interconnected Grid. “Heatwaves have become a normal part of our lives. They last longer and we record higher temperature every year.”
This new interdisciplinary center is aimed at fortifying the region’s power infrastructure against the floods, high winds, drought, even cold snaps that are also taking a heavier toll on the West’s energy systems. This vulnerability poses significant challenges to maintaining essential services, from health care to transportation and communication.
The international effort has secured nearly $9 million in federal grants from the U.S. and Canadian governments to explore ways to shore up the grid, known as the Western Interconnection, in the face of growing threats associated with global warming.
“Our standard of living depends on power systems, but we only realize that when we don’t have power,” Parvania said. “We want to avoid outages from happening with the growing number, intensity and duration of the adverse weather.”
Joining Parvania at the helm of the new center is the University of Calgary’s Hamid Zareipour, a professor of electrical and software engineering. Some $5 million in funding is coming from the U.S. National Science Foundation with the rest coming from Canada’s Natural Sciences and Engineering Research Council.
The center will pursue a broad interdisciplinary approach, tapping faculty from across the Utah campus, namely co-principal investigators Valerio Pascucci of the Scientific Computing and Imaging Institute, biologist William Andregg, director of the Wilkes Center for Climate Science and Policy, and Divya Chandrasekhar, associate professor in the Department of City and Metropolitan Planning.
“Collectively, these resources can facilitate the resilience of critical power grid infrastructure against extreme conditions,” said Erin Rothwell, the university’s vice president for research. “This center solidifies the University of Utah’s leadership in power grid resilience research and technology innovation.”
The U.S.-Canada Center on Climate-Resilient Western Interconnected Grid brings together leading experts in power engineering, climate, forestry, data analysis, policy and social sciences from a network of 35 partners, including the Western Electricity Coordinating Council, or WECC.
“As the regional entity with a focus on grid reliability and security for the Western Interconnection, we believe this new interdisciplinary center at the University of Utah will align greatly with the work of WECC,” Branden Sudduth, the nonprofit’s vice president of reliability planning and performance.
Extreme weather events aren’t the only challenge the grid faces.
“Additionally, much of the resource mix is changing from conventional generation to high penetrations of weather-dependent clean energy resources,” Sudduth said. “Addressing this through a multi-faceted, cross-collaboration approach is the best way to ensure a reliable and secure power supply.”
The new center will create an innovative cyberinfrastructure (CI) dedicated to gathering and distributing climate and grid data within the Western Interconnection’s stakeholder community.
“Our primary aim is to develop a trustworthy CI framework that fosters secure collaboration and information sharing among participants from academia, industry, and government,” said Pascucci, director of the Center for Extreme Data Management Analysis and Visualization (CEDMAV) and John R. Parks Endowed Chair Professor of Computing. “This collaborative effort will provide the essential data for constructing and sharing customized models for risk quantification and forecasting of regional extreme climate disturbances.”

Key takeaways
Two-thirds of white Americans believe that Black Americans do not experience racism or racial inequities in health care.
UCLA psychologists exposed white study participants to the well-documented history of medical-related mistreatment of Black Americans.
Subsequently, white participants were more likely to adopt a new perspective and support policies aimed at reducing racial disparities in health care.
Being exposed to some of the many historical incidences of anti-Black racism in American health care can contribute to ...

Numerous studies have shown that leading a fulfilling and satisfying life may improve cognitive function by encouraging health-protective behaviors such as physical activity and reduced stress. Many of these studies assess this relationship from a population level, rather than among individuals.
But a closer look within the general population suggests that life satisfaction may not have a positive effect on all people, according to a new study led by Boston University School of Public Health researchers.

ANN ARBOR, Mich. – For some families, the year after childbirth may not only mean loads of diapers but stacks of unpaid medical bills as well.
Postpartum individuals are more likely to have medical debt than those who are pregnant, suggests a new Michigan Medicine led study that evaluated collections among a statewide commercially insured cohort of 14,560 pregnant people and 12,157 people in the postpartum period.
“Our findings suggest that current out-of-pocket costs before and after childbirth ...
Experimental researchers often find themselves of two minds when interacting with the public. On one side, researchers gather knowledge and test hypotheses based on participants’ responses. On the other side, they use their own knowledge and expertise to engage and educate the public about topics of public concern related to their science.

September 28, 2023 – Women undergoing autologous breast reconstruction – in which the breast is reconstructed using the patient's own tissues– report higher satisfaction with their breasts at follow-up, compared to those undergoing implant-based reconstruction, reports a study in a special October supplement to Plastic and Reconstructive Surgery®, the official medical journal of the American Society of Plastic Surgeons (ASPS). The journal is published in the Lippincott portfolio by Wolters Kluwer.

WASHINGTON (Sept. 28, 2023) — Grandmother was right: Scrubbing behind the ears and between the toes may help keep the skin in those regions healthy, or so says a new study by a team at the George Washington University.
The microbiome, or the collection of microbes living on and in the human body, are known to play a role in human health and the skin is no different. A new study by a team at the George Washington University has shown that the composition of the skin microbiome varies across dry, moist and oily regions of the skin.

UNIVERSITY PARK, Pa. — Every person hosts trillions of microorganisms, like bacteria and viruses, on their skin and in organs including those that make up the digestive tract, like their mouth, that collectively make up their microbiome. Microbiome research can lead to medical breakthroughs to treat diseases like inflammatory bowel syndrome and diabetes. According to Laura Weyrich, associate professor of anthropology and bioethics at Penn State, microbiome samples from Indigenous communities have played an important role in furthering Western ...
URBANA, Ill. – Family mealtimes are important for parents and children as a space to communicate, socialize, and build attachment relationships. But it can be difficult for busy parents to balance family and work life. A new study from the University of Illinois Urbana-Champaign explores how parents’ job stress influences their attendance at family mealtimes, and in turn, children’s socioemotional development.
“We all struggle to maintain the balance between work life and family life. But this might ...
