EXCERPT

More than 5,000 bees in Hobart, Australia, have been fitted with the RFID sensors, which measure a tenth of an inch all around. They will relay data to recorders placed around hives and known food sources and will in turn send the information to a central location. This will allow researchers to build a four-dimensional model of bee behavior and movements, which will help them understand what the bees come into contact with – such as farm pesticides – and how it may play a part in their decline.
