Plants may look inert and harmless, but, at any given moment, they’re waging chemical warfare against attackers, preparing tissues to withstand freezing temperatures, or synthesizing compounds that become medicines for humans. These leafy biochemists produce over a million chemicals, or metabolites, to help them survive their rooted existence. 

Couples who spend more time savoring the pleasurable moments they share are happier together, argue less and are more confident their relationship will last, University of Illinois Urbana-Champaign researchers say in a new study.

“Savoring involves slowing down to become aware of and focus on positive experiences,” said first author Noah Larsen, a graduate student at Illinois. “Savoring can occur when we reminisce on a past experience, focus on the present moment or look ahead to a future experience.”

When couples attend relationship counseling, it benefits not only their partnership but also their individual well-being. But which aspects of the training are most influential in this respect? A new study from the University of Illinois Urbana-Champaign examines how a popular intervention program affected individual outcomes such as mental health, sleep, and substance use. 

Keeping amphibians as pets offers hobbyists an opportunity to connect with the non-human world, often increasing interest in conserving animals in the wild. But there’s a dark side to the amphibian trade, according to a recent study from the University of Illinois Urbana-Champaign. 

The soil microbiome is critical for the ecosystem, and agricultural practices that promote microbial diversity can support plant health and help protect against pests. But it is unclear which practices are most beneficial, and what motivates farmers to choose them.

Corn bred with genes from wild relatives can reshape soil microbial communities and reduce nitrogen loss — with no yield reduction — according to new research from the University of Illinois Urbana-Champaign. The advancement marks the first time corn’s genetic makeup has been linked with inhibition of nitrifying and denitrifying bacteria, the microbes responsible for turning fertilizer nitrogen into forms that pollute water and contribute to climate change.   

In Bangladesh, programs targeting ultra-poor, rural households can help families escape extreme poverty. However, the programs may have the unintended consequence of reinforcing gender gaps, a new study from the University of Illinois Urbana-Champaign finds.

Despite improvements in economic and social empowerment, women in many countries still have little control over their own fertility and reproductive health. A new study from the University of Illinois Urbana-Champaign explores a program reducing barriers to family planning by providing financial and peer support to women in Uttar Pradesh, India’s most populated state.

Scientists at the University of Illinois Urbana-Champaign can now differentiate between human-derived and hydrological contributions of riverine nitrogen pollution in the Upper Mississippi River Basin. The advancement, published in Environmental Science and Technology, sets the stage for more nuanced policy and management of nitrate and nitrite, the nutrients that degrade drinking water quality and cause oxygen-starved “dead zones” in the Gulf each year.

Illinois may be famous for being the Land of Lincoln and home of “Da Bears,” but few are familiar with one of its lesser claims to fame, which lies underground.

The commercial cultivation of horseradish in Southern Illinois took root in the 1850s, when German immigrant farmers discovered that the region’s sandy, nutrient-rich soil created an ideal environment for the unassuming crop to thrive.
