Flies, Too, Drink to Get Over It

While studying the relationship between stress and alcohol in fruit flies, a group of neuroscientists found that sexually frustrated male flies were more likely to prefer food spiked with alcohol than their carnally satisfied peers, suggesting that humans aren’t the only species to self-medicate. —ARK

The New York Times:

The study, posted online in the journal Science, suggests that some elements of the brain’s reward system have changed very little during evolution, and these include some of the mechanisms that support addiction. Levels of a brain chemical that is active in regulating appetite predicted the flies’ thirst for alcohol. A similar chemical is linked to drinking in humans.

“Reading this study is like looking back in time, to see the very origins of the reward circuit that drives fundamental behaviors like sex, eating and sleeping,” said Dr. Markus Heilig, the clinical director of the National Institute on Alcohol Abuse and Alcoholism and the National Institute on Drug Abuse.

I wonder how much tax money was used in funding this earth shattering piece of research?

How do you determine if a male fruit fly is sexually frustrated, besides obviously
not through asking or taking a survey correlating sexual frustration and
alcoholism?  Doesn’t the sexual frustration or perception of it in observing female
fruit flies count, or is this research skewed in a highly sexist manner? 

Facetiousness aside, this is a worthless but highly expensive study that is being
hyped into something significant.  It’s somewhat like research and development in
the weapons industry, in that “scientific” studies similar to this are developed because plenty of money is there for it—but at least it’s mostly wasteful and pointless, rather than lethal.

Masturbating baboons, sexually frustrated flies…

It seems there is no end to lengths which some scientists will go to occupy themselves.

These redundant “experiments” which prove nothing we do not already know, are nothing less than yet another sick manifestation of how far we have strayed as a society from basic common sense and decency in deference to the inhumane uncompassionate institution and its, overproccessed credentialed servants.

And what do we really gain from all this nonsense???

B.F. Skinner’s torture of dogs, should have elicited outrage. Instead he was praised, and he discovered nothing really new.

As I see it he only managed to condition himself to act cruelly, and helped to create a culture in which such cruelty was acceptable and in fact inseperable from this backwards approach to obtaining a quantifiable body of useful knowledge.

Now, it appears these methods are becoming not only the means, but the end itself.
