In a new study, Andrew Dickerson, Ph.D. (left), of the University of Central Florida, set out to discover how mosquitoes locate and penetrate tiny holes in bed netting, which can be of special importance in tropical areas of the world that are infested with disease-causing species. Dickerson is an assistant professor of mechanical engineering. (Earlier this year, he and graduate student Nicholas Smith (right) were involved in another attention-getting study of natural mechanics: how oranges release microjets of fragrant oil when squeezed. The microjet information could help pharmaceutical companies develop new ways to deliver airborne medications.) (Photo credit: Karen Norum, University of Central Florida)
