URBANA, Ill. – Australian pineapple, Danish trout, and Midwestern U.S. corn farmers are not often lumped together under the same agricultural umbrella. But they and many others who raise crops and animals face a common problem: excess nitrogen in drainage water. Whether it flows out to the Great Barrier Reef or the Gulf of Mexico, the nutrient contributes to harmful algal blooms that starve fish and other organisms of oxygen.

URBANA, Ill. – Before humans can benefit from new drug therapies and nutritional additives, scientists test their safety and efficacy in animals, typically mice and rats. But, as much as they’ve done for biomedical research, rodents aren’t always the best research model for studies on neonatal brain development and nutrition. That’s where pigs can play an important role.

University of Illinois researchers say the domestic pig is ideal for these studies because their brain size, rate of development, and digestive system are excellent analogues for human newborns.

URBANA, Ill. – When scientists need to understand the effects of new infant formula ingredients on brain development, it’s rarely possible for them to carry out initial safety studies with human subjects. After all, few parents are willing to hand over their newborns to test unproven ingredients.

URBANA, Ill. – Ever thought about buying or building a bat box to help bats? Think carefully about the design and where you put it, University of Illinois researchers say.

Here’s why: Bats and their pups can overheat and die in poorly designed or placed bat boxes, and in a warming climate, it could happen more often.

URBANA, Ill. – Pumpkin growers dread the tiny tan scabs that form on their fruit, each lesion a telltale sign of bacterial spot disease. The specks don’t just mar the fruit’s flesh, they provide entry points for rot-inducing fungus and other pathogens that can destroy pumpkins and other cucurbits from the inside out. Either way, farmers pay the price, with marketable yields reduced by as much as 90%.

URBANA, Ill. – Land managers know one of the best ways to prevent forest fires is to set fires. Periodic controlled or prescribed burns can reduce the amount of flammable materials lying about on a forest floor, so when wildfires do start, they stay small.

Prescribed fires do more than that, though. New University of Illinois research shows frequent fires can help keep invasive plants in check by reducing nitrogen availability in soils.

URBANA, Ill. – Corn didn’t start out as the powerhouse crop it is today. No, for most of the thousands of years it was undergoing domestication and improvement, corn grew humbly within the limits of what the environment and smallholder farmers could provide.

For its fertilizer needs, early corn made friends with nitrogen-fixing soil microbes by leaking an enticing sugary cocktail from its roots. The genetic recipe for this cocktail was handed down from parent to offspring to ensure just the right microbes came out to play.

URBANA, Ill. -- Agricultural scientists who study climate change often focus on how increasing atmospheric carbon dioxide levels will affect crop yields. But rising temperatures are likely to complicate the picture, researchers report in a new review of the topic.

CHAMPAIGN, Ill. — The chronic stress of living in neighborhoods with high rates of violence and poverty alters gene activity in immune cells, according to a new study of low-income single Black mothers on the South Side of Chicago.

URBANA, Ill. – If you haven’t been the parent or caregiver of an infant in recent years, you’d be forgiven for missing the human milk oligosaccharide trend in infant formulas. These complex carbohydrate supplements mimic human breast milk and act like prebiotics, boosting beneficial microbes in babies’ guts.

Milk oligosaccharides aren’t just for humans, though; all mammals make them. And new University of Illinois research suggests milk oligosaccharides may be beneficial for cats and dogs when added to pet diets.
