Summer beckons in the northern latitudes. As temperatures warm, beachgoers will flood sandy coasts, carrying bags of potato chips and sandwiches. Picnics will sprout in parks supplied with pink watermelon wedges and soda pop. Feasts ripe for people, and undoubtedly bugs too. In mere seconds flies and bees can swarm, but how do they sniff out food so fast? Knowing how to fly could be the reason, according to new research from the Max Planck Institute for Chemical Ecology.
