Study tracks bees using miniature antennae

The struggle continues for our tiny pollinating friends.

Recently on the program, we've told you about mass bee deaths in Oregon and Ontario, with growing research pointing toward the harmful affects of pesticides on bee populations.

Now, researchers at the Freie Universität Berlin have isolated just how pesticides may be affecting bees and potentially causing these die-offs. All through the use of some tiny technology to help with the experiments. Dr. Randolf Menzel explains.
