Laser scanners at the entrance of the hive read the bar codes to monitor how long each bee had been gone from the hive. By keeping (144) of individual bees, scientists hope to learn more about honey production. Knowing how far bees travel to gather pollen and how many trips they make back to the hive could eventually help beekeepers predict honey yields. [br]
