University of Illinois dining halls voluntarily label foods with nutrition information. Although 45 percent of students noticed the labels, only 20 percent used the labels to make food choices. Students who practice health-promoting behaviors like tracking what they eat or exercising frequently are most likely to use nutrition information on food items in the dining hall.
In a small study to determine the best way to assess the operating skills of would-be orthopaedic surgeons, Johns Hopkins researchers found that tracking the trainees' performance on cadavers using step-by-step checklists and measures of general surgical skills works well but should be coupled with an equally rigorous system for tracking errors.
Researchers from the University of Missouri and partner institutions are exploring how ethnic and gender variables affect retention rates, goal setting and satisfaction among engineering students. Preliminary findings in the middle of this five-year study found no differences in retention between Latino and white engineering students, but did show differences between men and women. Their study could help shape methods needed to retain students in engineering fields.

A study compared strategies using water-soluble fertilizers (WSF) and controlled-release fertilizers to provide adequate nutrition during production and consumer phases of petunia. After 42 days in the production study, all fertilizer strategies produced horticulturally acceptable plants. In the 'consumer phase' study, plant performance was greatly improved for plants with residual fertilizer compared with WSF. The study includes economic analyses of the various management strategies.
A study investigated the effects of ultraviolet-B (UV-B) light on cool-season turfgrasses (tall fescue, creeping bentgrass, and perennial ryegrass). Experiments demonstrated that exposure to UV-B resulted in a decline of growth rate and color in cool-season turfgrasses within two weeks. Coarse-textured turf grasses (tall fescue and perennial ryegrass) had higher growth rates compared to finer-textured varieties, and the coarser-leaved plants maintained acceptable color levels compared with the finer-textured creeping bentgrasses.
Teacher burnout and student stress may be linked, according to a University of British Columbia study. The study is the first of its kind to examine the connection between teacher burnout and students' cortisol levels, which are a biological indicator of stress.
As the solar industry booms, coal workers have the opportunity to pursue new work. A study from Michigan Technological University and Oregon State University looks at what it takes to retrain underground skills for sunnier prospects.
