Researchers at Penn State came up with a small but mighty way to learn honeybees' hive secrets, and you must see it to bee-lieve it! Scientists glued teeny tiny QR codes, that are smaller than a pinky nail,

New insights into bee movements and life cycles have been uncovered after researchers tracked the insects using tiny QR codes glued onto their backs.

At Penn State, a new study using QR codes smaller than a fingernail is being done to learn more about bees. KDKA's Jessica Guay spoke with some of the researchers about their work.
