CHAMPAIGN, Ill. — Researchers often study the genomes of individual organisms to try to tease out the relationship between genes and behavior. A new study of Africanized honey bees reveals, however, that the genetic inheritance of individual bees has little influence on their propensity for aggression. Instead, the genomic traits of the hive as a whole are strongly associated with how fiercely its soldiers attack.

URBANA, Ill. – Underground tunnels have been used by warriors and smugglers for thousands of years to infiltrate battlegrounds and cross borders. A new analysis published in the Open Journal of Soil Science presents a series of medieval and modern case studies to identify the most restrictive and ideal soil and geologic conditions for tunneling.

URBANA, Ill. ­–  As University of Illinois employees and students return in the fall, safety measures to limit the spread of COVID-19 are critical. University administrators have announced a partial return to normal activities, with a combination of in-person and online instruction. Precautions include limited crowd sizes, frequent cleaning of classrooms, and hand sanitizer stations in all buildings.

URBANA, Ill. – Food banks help alleviate food insecurity, and their contribution has become increasingly important during the COVID-19 pandemic. Food banks receive supplies from many sources, including major food retailers, but little is known about their role in the food supply chain.

A team of researchers received a $500,000 grant from the USDA National Institute of Food and Agriculture (NIFA) to study the relationship among food retailers, food banks, and food security.

CHAMPAIGN, Ill. — The crops we grow in the field often form dense canopies with many overlapping leaves, such that young “sun leaves” at the top of the canopy are exposed to full sunlight with older “shade leaves” at the bottom. In order to maximize photosynthesis, resource-use efficiency, and yield, sun leaves typically maximize photosynthetic efficiency at high light, while shade leaves maximize efficiency at low light. 

URBANA, Ill. - Looking for a great time with the kids in your life this summer? Participate in a free and unique opportunity from the College of Agricultural, Consumer and Environmental Sciences (ACES) Alumni Association at the University of Illinois. Previously a multi-day experience on campus, ACES Family Academies – where alumni and many others share their experiences with young people – will go virtual for 2020.

URBANA, Ill. – Debra Korte has been named the first director for learning innovation and e-learning in the College of Agricultural, Consumer and Environmental Sciences (ACES) at University of Illinois.

Korte, previously a teaching assistant professor in the Agricultural Leadership Education and Communication program in ACES, assumed the new role in ACES’ Office of Academic Programs June 22.  

CHAMPAIGN, Ill. — Northern bobwhites are attracted to a habitat based on whether other bobwhites are present there, researchers at the University of Illinois at Urbana-Champaign report. This phenomenon, called conspecific attraction, could aid conservation efforts.

URBANA, Ill. – Like antibiotic-resistant bacteria, some herbicide-resistant weeds can’t be killed by available chemicals. The problem affects more than just the errant weed in our driveways; herbicide-resistant weeds threaten our food supply, stealing resources and outcompeting the crops that make up our breakfast cereal and feed the nation’s livestock.

The weed that represents the biggest threat to Midwestern corn and soybean production, waterhemp, has outsmarted almost every kind of herbicide on the market today.

URBANA, Ill. – Soil microbes are living, working barometers of soil health. They are responsible for turning atmospheric nitrogen into forms plants can use, and for releasing nitrogen back into the air. Farm management decisions undoubtedly affect these microscopic workhorses, but, until now, scientists didn’t have a full picture of how crop rotation and tillage influence the soil microbiome.
