CHAMPAIGN, Ill. —  I can barely hear Esther Ngumbi over the roar of greenhouse fans as she shows me around her rooftop laboratory in Morrill Hall. The benches are full of tomato plants, and the tomatoes don’t look good. Half of the plants are submerged in bins of water. Their leaves are yellow...

Researchers at the University of Illinois have contributed to a large-scale international study that has reconstructed a comprehensive "tree of life" for flowering plants.  The study offers new light on the evolutionary history of angiosperms, which account for approximately 90 percent of all...

The past attempts of honey bee researchers to inventory the fungal diversity in honey bee colonies revealed that Aspergillus flavus is frequently found in hives. In a new study, researchers have discovered that this fungus is uniquely adapted to survive in bee colonies. The...

Plant biologists report that a species of tree fern found only in Panama reanimates its own dead leaf fronds, converting them into root structures that feed the mother plant. The fern, Cyathea rojasiana, reconfigures these “zombie leaves,” reversing the flow of water to draw nutrients back...

It has long been known that exposure to pesticide sprays is harmful to honey bees. In a new study, researchers have uncovered the effect of such sprays on the sense of smell in bees, which could disrupt their social signals. Honey bees live in dynamic communities and constantly communicate with...

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...

CHAMPAIGN, Ill. — Researchers report that a single, simplified model can predict population fluctuations in three unrelated realms: urban employment, human gut microbiomes and tropical forests. The model will help economists, ecologists, public health authorities and others predict and respond to...

A five-year study at the University of Illinois Energy Farm found applying ground-up silicate rock to Midwestern farm fields can capture significant amounts of carbon dioxide and prevent it from accumulating in the atmosphere. Working with Eion Corp., researchers at the University of Illinois...
