Location, individual circumstances impact caregiver well-being, researchers find



Caregivers have higher well-being in urban areas, where more support is available, than those in suburban or rural areas, according to a new study



Penn State





UNIVERSITY PARK, Pa. — Roughly a quarter of adults in the U.S. are caring for elderly family members or children with an illness or disability — and sometimes both at the same time. Despite family caregiving consuming time and resources for both individuals and governments, social scientists don’t fully understand how it affects the people who do the caregiving, according to a team led by researchers at Penn State. In collaboration with colleagues at Purdue University and the University of Minnesota, the researchers conducted an expansive study of caregiver well-being, finding that the type of geographic location and individual circumstances can impact a caregiver’s health, comfort and happiness even more than their state’s family care policies.

In findings recently published in Rural Sociology, the researchers reported that rural and suburban caregivers were more likely to have low or medium well-being, and less likely to have high well-being compared to urban caregivers. And caregivers’ personal characteristics — such as age, income and education — had a stronger effect on their well-being than the family care policies of the state they live in. However, the researchers concluded, family-care policies can make a difference in well-being when they take into account the differences among rural, suburban and urban areas — especially in terms of available support and infrastructure.

“Although caregiving can be an emotionally rewarding and satisfying experience, caregivers often face significant stress and challenges in their roles, and the impacts of caregiving on well-being are often overlooked by researchers and policymakers,” said Elena Maria Pojman, first author on the paper and a doctoral degree candidate in sociology and demography in the Department of Sociology and Criminology at Penn State.

To understand caregiver well-being more clearly, including how it differs among rural, suburban and urban caregivers, the researchers used two publicly available datasets. One was the caregiving survey from the North Central Regional Development Center and is a collaboration with the Northeast Regional Center for Rural Development, which is based at Penn State. This survey includes survey responses from 4,620 caregivers about their lived realities looking after either children or adults in the North Central and Northeast regions of the United States. The other dataset was from a group of researchers at the University of North Carolina at Chapel Hill, and it includes information about state-level programs and policies connected to the availability of services such as respite care, daycare, special transportation and state-paid leave from their jobs for caregiving.

By merging these two datasets for the current study, the researchers assessed how caregivers are doing and whether state-level policies — laws and programs related to family care — play a role in caregiver well-being. First, the team’s analysis revealed that caregivers could be grouped by well-being ratings of high, medium or low, based on how they responded to several facets of their well-being: happiness, self-rated health and how caregiving has affected their physical health, mental/emotional health and social life. Then, the researchers used a statistical technique that predicts probability of an outcome with more than two categories to analyze how likely people from rural, suburban or urban areas were to fall into each category.

The researchers concluded rural and suburban caregivers were more likely to have lower well-being than urban caregivers, but the overall differences among the three were small. However, Pojman pointed out, the analysis indicated that suburban caregivers were more like rural caregivers than urban ones — which contradicts previous research by other scientists that grouped suburban and urban caregivers together.

“Suburban caregivers often face unique challenges stemming from their geographical and social position, which differ from the issues experienced in urban or rural environments,” Pojman said, explaining that the study highlighted the need for better-targeted policies and resources. “Balancing caregiving with work, parenting and personal needs is often compounded by suburban-specific factors such as limited public transit and the isolation that comes from living in more spread-out communities.”

The researchers also concluded that support systems are crucial — caregivers who had access to paid help and community support specific to caregiving tended to have higher well-being. Less specific support, like broad federal programs, was more weakly linked to high well-being. This suggests that policy should focus on making caregiving-specific supports more accessible, explained team leader and senior author, Florence Becot, Nationwide Insurance Early Career Professor of Agricultural Safety and Health Program Lead in Penn State’s College of Agricultural Sciences

“Although caregiving can be an emotionally rewarding and satisfying experience, caregivers often face significant stress and challenges in their roles, and the impacts of caregiving on well-being are often overlooked by researchers and policymakers,” she said. “Caregivers often report a complex range of feelings regarding the care they provide and its impact on their life, ranging from immense financial and emotional burdens, to joy and personal growth. There’s a clear need for better family-care policies that reflect the real differences in support needs across rural, suburban and urban areas — especially to help those caregivers who are struggling.”

Because caregiving experiences vary so much, it’s important to consider caregiver well-being in a nuanced and individualized way, Becot added.

“Understanding the challenges caregivers face in different social, demographic and geographic contexts and circumstances helps researchers, health care providers and policymakers better support caregivers — especially those at risk of burnout or emotional distress,” she said.

Animations of wildlife tracking data help explore animal movements



Flexible mapping tool allows researchers to visualize large datasets




Ohio State University




COLUMBUS, Ohio – Researchers have developed new software for exploring and communicating animal movements in the wild. 

This suite of open-source tools, called ECODATA, was designed to support the analysis and visualization of complex datasets, as valuable observations about animal movement are often made by analyzing massive amounts of wildlife tracking data. 

Their tool accomplishes this by creating animations that help ecologists study animal movement, such as how extreme weather conditions or seasonal vegetation growth might influence a species’ normal activities, said Gil Bohrer, co-author of the study and a professor in civil engineering and geodetic engineering at The Ohio State University. 

“We’re not creating new information, but we are taking data that ecologists typically find hard to utilize and making it easy and accessible,” said Bohrer. “This can help users understand an ecosystem and quickly identify what’s going on, or test a good hypothesis they have.”

ECODATA works by combining direct wildlife location observations with complex remote sensing and geospatial data to process image frames into multiple layers of customizable maps.

For example, in one case study, the researchers used the software to animate movements of elk and wolves in relation to roads, wildlife crossing structures and changes in seasonal vegetation near Banff National Park in Canada.

Although interpreting and integrating large datasets into research and other wildlife applications can be a difficult and tedious process, ECODATA makes it easy to create animations that act as powerful tools for illustrating study results, supporting animal exploration in uncharted territories, and even aiding wildlife managers in garnering support for conservation efforts, said Bohrer. 

“These animations are very effective,” he said. “They can process and plot lots of changing environmental conditions and corresponding animal movement in a really temporally dynamic way.”

The study was recently published in the journal Methods in Ecology and Evolution.

Previous attempts at creating user-friendly research software required scientists to have some programming skills, but what makes ECODATA unique is that it is flexible enough that scientists don’t need technical skills to employ it, said Justine Missik, lead author of the study and a researcher in civil, environmental and geodetic engineering at Ohio State.  

“There are all sorts of environmental datasets that are out there that are difficult for people to work with,” she said. “Our project was helping address those research gaps.”

In this paper, researchers demonstrated ECODATA’s abilities through two case studies, both of which answered very different questions about its potential uses, said Bohrer. 

In the case study of elk and wolves in Banff, the animation researchers developed showed that both species migrate from the northeast during late spring to their summer range, where some spend considerable time near highways, including during times that coincide with peak annual traffic volumes. 

The second case illustrated how the software could be used in wildlife management, as ECODATA’s animation could inform wildlife managers about the timing and location of caribou movements during their birthing season. These visual insights helped reveal territory in the caribou’s seasonal range that management hadn’t previously recognized. This can help wildlife managers understand the conservation impacts of caribou movements.  

That ECODATA can help identify such situations makes it a valuable resource for many purposes, most notably as an asset for protecting all kinds of wildlife. “These animations are tools to explore the data in a different way, by many different users in many different contexts,” said Bohrer. 

Moving forward, the team hopes that the custom animations ECODATA provides work as a complement to existing research tools and inspire more detailed explorations of ecological models used for impactful, sustainable decision-making.

Rice University researchers, in collaboration with international partners, have developed the first eco-friendly technology to rapidly capture and destroy toxic “forever chemicals” (PFAS) in water. The findings, recently published in Advanced Materials, mark a major step toward addressing one of the world’s most persistent environmental threats.

The study was led by Youngkun Chung, a postdoctoral fellow under the mentorship of Michael S. Wong, a professor at Rice’s George R. Brown School of Engineering and Computing, and conducted in collaboration with Seoktae Kang, professor at the Korea Advanced Institute of Science and Technology (KAIST), and Keon-Ham Kim, professor at Pukyung National University in South Korea.

What are PFAS?

PFAS, short for per- and polyfluoroalkyl substances, are synthetic chemicals first manufactured in the 1940s and used in products ranging from Teflon pans to waterproof clothing and food packaging. Their ability to resist heat, grease and water has made them valuable for industry and consumers. But that same resistance means they do not easily degrade, earning them the nickname “forever chemicals.”

Today, PFAS are found in water, soil and air around the globe. Studies link them to liver damage, reproductive disorders, immune system disruption and certain cancers. Efforts to clean up PFAS have struggled because the chemicals are difficult to remove and destroy once released into the environment.

Limitations of current technology

Traditional PFAS cleanup methods typically rely on adsorption, where molecules cling to materials like activated carbon or ion-exchange resins. While these methods are widely used, they come with major drawbacks: low efficiency, slow performance, limited capacity and the creation of additional waste that requires disposal.

“Current methods for PFAS removal are too slow, inefficient and create secondary waste,” said Wong, the Tina and Sunit Patel Professor in Molecular Nanotechnology and professor of chemical and biomolecular engineering, chemistry and civil and environmental engineering. “Our new approach offers a sustainable and highly effective alternative.”

A breakthrough material with real-world promise

The Rice-led team’s innovation centers on a layered double hydroxide (LDH) material made from copper and aluminum, first discovered by Kim as a graduate student at KAIST in 2021. While experimenting with these materials, Chung discovered that one formulation with nitrate could adsorb PFAS with record-breaking efficiency. 

“To my astonishment, this LDH compound captured PFAS more than 1,000 times better than other materials,” said Chung, a lead author of the study and now a fellow at Rice’s WaTER (Water Technologies, Entrepreneurship and Research) Institute and Sustainability Institute. “It also worked incredibly fast, removing large amounts of PFAS within minutes, about 100 times faster than commercial carbon filters.”

The material’s effectiveness stems from its unique internal structure. Its organized copper-aluminum layers combined with slight charge imbalances create an ideal environment for PFAS molecules to bind with both speed and strength.

To test the technology’s practicality, the team evaluated the LDH material in river water, tap water and wastewater. In all cases, it proved highly effective, performing well in both static and continuous-flow systems. The results suggest strong potential for large-scale applications in municipal water treatment and industrial cleanup.

Closing the loop: Capture and destroy

Removing PFAS from water is only part of the challenge. Destroying them safely is equally important. Working with Rice professors Pedro Alvarez and James Tour, Chung developed a method to thermally decompose PFAS captured on the LDH material. By heating the saturated material with calcium carbonate, the team eliminated more than half of the trapped PFAS without releasing toxic by-products. Remarkably, the process also regenerated the LDH, allowing it to be reused multiple times.

Preliminary studies showed the material could complete at least six full cycles of capture, destruction and renewal, making it the first known eco-friendly, sustainable system for PFAS removal.

Global effort, global impact

“We are excited by the potential of this one-of-a-kind LDH-based technology to transform how PFAS-contaminated water sources are treated in the near future,” Wong said. “It’s the result of an extraordinary international collaboration and the creativity of young researchers.”
