Where Could They Bee?

Since I was just writing recently about bees, I would be remiss if I did not mention that the bees seem to be going on vacation. Or, to be a little more scientific about it, they're disappearing. By the billions.

As the various articles point out, food crops that rely on honeybees for pollination are worth about $15 billion and include a lot of the fruits and nuts that we all love the most: apples, cherries, almonds, and so forth. There is no adequate mechanical substitute for the pollinating prowess of the honeybee, so if this unknown process should continue, it is reasonable to expect that these staples of our diet will not disappear but will become very expensive from simple scarcity. (Imagine a ten dollar slice of pie.) (Okay, in Los Angeles that's not so far from the truth, but imagine it in Dubuque.)

Bee colonies started to collapse last October: huge numbers of worker bees would simply never return to the hive, up to 50% of the colony in many cases. As CNN reports, most of these bees just plain vanished, and their little bee bodies were never found. Since their failure to return was possibly a failure in their navigation systems, speculation ran rampant on all sorts of causes, including cellphone towers (leading Bill Maher last week to ask, "will we choose to literally blather ourselves to death?"). This New York Times article goes into more detail on the science involved, including this disturbing photo of cross-sections of diseased (left) and healthy (right) bee thoraxes:

A chemical trigger for all this seems most likely, particularly since some hives treated with gamma radiation have begun to recover, suggesting that the gamma is killing some yet-unknown pathogen. But research has barely begun on the problem, and all the while, the bees keep disappearing; and despite some lucky breaks, like the fact that Baylor College of Medicine recently happened to finish sequencing bee DNA (thus speeding up immeasurably a search for genetic triggers), we have no idea how long it will take to find answers to this problem.

Diseased bees are being found to be contaminated with fungi common in humans whose immune systems have been depressed by AIDS or cancer. Thus we learn yet again, we're all connected. The question then becomes, if the bees go, what happens to us?
