From the article :

[...] The theory is that radiation from mobile phones interferes with bees' navigation systems, preventing the famously homeloving species from finding their way back to their hives. Improbable as it may seem, there is now evidence to back this up.

Colony Collapse Disorder (CCD) occurs when a hive's inhabitants suddenly disappear, leaving only queens, eggs and a few immature workers, like so many apian Mary Celestes. The vanished bees are never found, but thought to die singly far from home. The parasites, wildlife and other bees that normally raid the honey and pollen left behind when a colony dies, refuse to go anywhere near the abandoned hives.

If other bees and things aren't going anywhere near the stricken hives, doesn't it stand to reason that there may be something in the pollen as well?

My bet is it's a combination of factors, but I'm hoping for cel phones. I can't stand the things, but it ought to be easier to re-regulate them into a non-bee-killy spectrum than it would be to, say, get Monsanto or whoever to stop being stupid.

Poor bees. :|
