Institute for Genomic Biology director Gene Robinson and his colleagues found that changes in brain metabolism influence insect aggression.

Researchers boost insect aggression by altering brain metabolism

Scientists report they can crank up insect aggression simply by interfering with a basic metabolic pathway in the insect brain. Their study, of fruit flies and honey bees, shows a direct, causal link between brain metabolism (how the brain generates the energy it needs to function) and aggression.

Scientists are searching through a massive collection of 20-million-year-old amber found in the Dominican Republic more than 50 years ago, and the effort is yielding fresh insights into ancient tropical insects and the world they inhabited.

University of Illinois Institute for Genomic Biology director Gene Robinson, left, and citizen scientist Paul Tenczar put RFID tags on honey bees to track the activity of individual bees in the hive.

Radio frequency ID tags on honey bees reveal hive dynamics

Published Date:July 22, 2014

Scientists attached radio-frequency identification (RFID) tags to hundreds of individual honey bees and tracked them for several weeks. The effort yielded two discoveries: Some foraging bees are much busier than others; and if those busy bees disappear, others will take their place.

University of Illinois kinesiology and community health professor Marni Boppart studies the mechanisms that enable muscles to recover and grow stronger after exercise.

Stem cells aid muscle repair and strengthening after resistance exercise

A new study in mice reveals that mesenchymal (mezz-EN-chem-uhl) stem cells (MSCs) help rejuvenate skeletal muscle after resistance exercise.

Gene activity changes in response to dietary changes in foraging honey bees, researchers found.

Scientists track gene activity when honey bees do and don't eat honey

Many beekeepers feed their honey bees sucrose or high-fructose corn syrup when times are lean inside the hive. This practice has come under scrutiny, however, in response to colony collapse disorder, the massive -- and as yet not fully explained -- annual die-off of honey bees in the U.S. and Europe. Some suspect that inadequate nutrition plays a role in honey bee declines.
