Ozone (O₃) in the troposphere negatively impacts crop growth and development, causing significant decreases in crop yield worldwide. This airborne pollutant does not come directly from smokestacks or vehicles, but instead is formed when other pollutants, mainly nitrogen oxides and volatile organic compounds, react in the presence of sunlight. In an increasingly polluted atmosphere, understanding what plants are tolerant of O₃ is critical to improving crop productivity and resilience.

URBANA, Ill. — A new conservation tool from the University of Illinois Urbana-Champaign is helping protect lions across Africa, where populations have plummeted in recent decades due to poaching and other factors. With the Lion Localizer and a simple DNA test, authorities can examine the geographic origin of illegally traded teeth, claws, bones, and other body parts from  the poached animals.   

Waterhemp, the aggressive weed threatening Corn Belt crop production, is throwing curveballs once again, according to researchers at the University of Illinois Urbana-Champaign. The weed has famously developed resistance to not one or two, but seven herbicide sites-of-action classes, nearly exhausting the chemical tools farmers can use to defend their livelihood.

Cat owners want Kitty to be happy, but providing an abundance of food and snacks can have unintended consequences. Feline obesity is on the rise, impacting the health, longevity, and wellbeing of cats. A new study from the University of Illinois Urbana-Champaign looks at what happens in the digestive system and gut microbiota when cats eat too much.

URBANA, Ill. – Married couples and long-term romantic partners typically engage in a variety of behaviors that sustain and nourish the relationship. These actions promote higher levels of commitment, which benefits couples’ physical and psychological health.

URBANA, Ill. – Nanozymes are synthetic materials that mimic the properties of natural enzymes for applications in biomedicine and chemical engineering. They are generally considered too toxic and expensive for use in agriculture and food science. Now, researchers from the University of Illinois Urbana-Champaign have developed a nanozyme that is organic, non-toxic, environmentally friendly, and cost effective.

CHAMPAIGN, Ill. — A multiyear analysis tested whether management zone maps based on soil conditions, topography or other landscape features can reliably predict which parts of a cornfield will respond best to higher rates of seeding or nitrogen application. The study found that – contrary to common assumptions – crop-plot responses to the same inputs vary significantly from year to year. The most unpredictable factor – the weather – seemed to have the biggest impact on how the crops responded to these inputs.

The new findings are reported in the Agronomy Journal. 

URBANA, Ill. – When we’re married or in a long-term romantic relationship, we may eventually come to take each other for granted and forget to show appreciation. A new study from the University of Illinois Urbana-Champaign finds that it doesn’t have to stay this way.

The study examined why perceived gratitude from a spouse or romantic partner changes over time, and whether it can be improved through relationship intervention programs.

In a breakthrough for environmentally friendly chemical production, researchers at the Center for Advanced Bioenergy and Bioproducts Innovation (CABBI) have developed an economical way to make succinic acid, an important industrial chemical, from sugarcane.

URBANA, Ill. — As we hurtle toward crucial tipping points on a warming planet, an international team of scientists is recruiting a surprising ally to make a powerful dent in greenhouse gas emissions: the cow. Animal sciences researchers from the University of Illinois Urbana-Champaign are driving a new project to reduce methane production resulting from rumen fermentation in beef and dairy cattle.
