Todd Woody recently wrote a piece about a new research effort to understand the behavior of bees doing the essential work of pollinating plants in our food supply. As he writes at Quartz,
Australian scientists have devised a way to pinpoint the causes of the global die-off of bees that pollinate a third of the world’s crops: Attach tiny sensors to 5,000 honey bees, and follow where they fly.
The sensors, each measuring 2.5 millimeters by 2.5 millimeters (0.1 inch by 0.1 inch), contain radio frequency identification chips that broadcast each bee’s location in real-time. The data is beamed to a server, so scientists can construct a three-dimensional model of the swarm’s movements, identifying anomalies in their behavior.
Worker bees tend to follow predictable daily schedules—they don’t call them drones for nothing—leaving the beehive at certain times, foraging for pollen, and returning home along well-established routes. Variations in their routines may indicate a change in environment, such as exposure to pesticides.
