The COVID-19 pandemic upended life for individuals and communities worldwide. Social isolation, health mandates, illness, and economic hardships took a toll on the well-being of families and children, but there were also silver linings to people’s experiences. A new study from the University of Illinois Urbana-Champaign looks at impacts of the pandemic among youth and parents across the U.S. Midwest.

Self-checkout registers have become ubiquitous in grocery stores as they provide convenience and efficiency for customers. They also offer more privacy with no human directly monitoring your purchases. A new study from the University of Illinois Urbana-Champaign looks at whether shoppers prefer self-checkout when buying potentially stigmatized items, including condoms, pregnancy tests, period products, hemorrhoid cream, and diarrhea relief.

Imagine a prairie. How many plant species do you see? Maybe you’re picturing yellow coneflowers, some little bluestem, perhaps a few asters. But plant ecologists at the University of Illinois Urbana-Champaign say these ecosystems are much more diverse than many people realize.

Gaining a better understanding of how romantic relationships develop over time is key to helping couples maintain a satisfying union and overcome challenges. Researchers and practitioners rely on theories to provide insights, and it’s important that they are accurate and reliable. A new paper from the University of Illinois Urbana-Champaign discusses how contemporary methodologies can be applied to common relationship theories in a more rigorous way.

Access to nature promotes physical and mental health, and it is vital for children’s social and emotional development. Outdoor activities also influence family dynamics, helping to reduce stress and encourage connections. A new study from the University of Illinois Urbana-Champaign examines how green spaces and outdoor structures near the family residence interact with other factors in the household environment to influence executive functioning in early childhood.

Drones can now detect subtle soybean canopy damage from dicamba at one ten-thousandth of the herbicide’s label rate — simulating vapor drift — eight days after application. This advancement in remote sensing from the University of Illinois Urbana-Champaign provides a science-based tool to accurately detect and report crop damage at the field scale, reducing human error and bias. 

While the majority of Midwestern farmers rotate corn and soybeans, commodity prices and corn yield advantages compel some to plant corn year after year. Although foundational research on the benefits of corn-soybean rotation goes back decades, University of Illinois Urbana-Champaign scientists are working to address remaining holistic questions about crop yield, environmental impacts, and economic returns under various crop rotation scenarios. 

The global food system faces growing risks from climate change, even as farmers seek to adapt, according to a June 18 study in Nature.

In contrast to previous studies suggesting that warming could increase global food production, the researchers estimate that every additional degree Celsius of global warming on average will drag down the world’s ability to produce food by 120 calories per person per day, or 4.4% of current daily consumption. 

Gully erosion is the most severe form of soil erosion, and it can seriously impact agricultural fields, contributing to sediment loss and nutrient runoff into waterways. Gullies can be triggered suddenly by a single heavy rainfall event, creating deep channels that are difficult to rehabilitate even with heavy machinery. Accurately predicting where gully erosion is likely to occur allows agricultural producers and land managers to target their conservation efforts more effectively.
