Several folks sent this one in and/or blogged it: Locusts Inspire Technology That May Prevent Car Crashes.
"Locusts are commonly associated with plagues, food shortages, and death. But for a team of European scientists, the grasshopper-like insects are inspiring a technology that may save lives by preventing hundreds of thousands of car crashes.
"Locusts are good at avoiding collisions," said team member Claire Rind, a biologist at the University of Newcastle upon Tyne in England. "We should learn from a species that is good at the task."
"The insects migrate in swarms as dense as 80 million adults per square kilometer (0.4 square mile) yet avoid crashing into each other and the mouths of predatory birds."
