Couch Potato Gene Identified In Fruit Flies
Pickens writes "University of Pennsylvania biologists have discovered a mutation in fruit flies aptly named the 'couch potato' gene that allows them to simply chill out — entering a mild state of quasi-hibernation known as diapause, when winter arrives. 'It's not like they're bears sleeping in a cave,' says Paul Schmidt. 'They just look like they're a little bit more sluggish.' The couch potato gene, first discovered in the early 1990s, got its nickname because flies with mutations in the gene became really sluggish and behaved abnormally. Little is known about the underlying evolutionary genetic architecture, but in diapause, the slacking off is far less severe. The flies' bodily functions slow down, and they are better able to tolerate stress. The fruit fly gene may have implications for human health, as it can help biologists study the function of the nervous system and diseases such as epilepsy, refuting a recent statement by a political candidate that fruit fly research has 'little or nothing to do with the public good.'"
As already said, funding everything is sort of a bad idea. We have to make cuts where we can, and this program honestly looks like it holds little promise without other major scientific advances. Until human gene modification becomes plausible, there's no point in sinking our imaginary dollars into fruit fly programs.
So you're saying it might be time to change the way we decide who gets scientific funding, that the "Guess a number between one and ten" method we have, where if you guess the right number, your scientific proposal gets funded, might be a BAD system? Maybe we should start thinking about funding only the most important, worthwhile studies? Whoa man...
Waitafuckingminute, THAT'S ALREADY WHAT WE DO! There's this organization, called the National Institute of Health, that hands out a lot of grant money for biomedical research. Scientists spend a lot of their time filling out grant applications in the vain attempt to get them to fund their research, it's very competitive, a LOT of good studies don't get funding.
The ones that do are chosen by panels of other scientists and experts (though any scientist who has had a grant rejected will tell you, they're not perfect). They have a deeper understanding of what the benefits of research projects are than Sarah Palin, although that wouldn't be a high bar to clear. Yet they chose to fund fruit fly projects.
Hmm... a panel of biomedical experts think fruit fly research isn't a waste. Maybe they are crazy or corrupt, or maybe you don't really know as much about it as you think you do.
You can't jump right to the end in science, there is a lot of preliminary data you need to know usually before you can get a cure for X disease. For instance, with syphilis we had to first realize what bacteria were, realize it was a bacteria, realize that penicillin could kill bacteria, THEN we were able to cure it. You could have dumped all the money in the world into finding a cure for syphilis before we knew anything about that. You may have gotten lucky, but it's unlikely.
Similar with human diseases, knowing the genetics involved is ABSOLUTELY essential knowledge, even if we can't directly cure the genes yet.
Cancer treatments have improved greatly because of genetic work often done in flies. We can identify genes involved, then find out what they're doing in human cancers, then make treatments based on that.
One current hot prospect in cancer research is knocking out members of the kinesin family, a protein that moves along the cytoskeleton and is involved in cell division. Cell division goes haywire in cancer, if we could affect only one time of kinesin, it would stop cancer pretty well.
Know how we discovered kinesin? By studying squids and fruit flies.
To sum up: unless you're out there reading whole grant applications, don't say a study is worthless or scientists are lying about the outcomes of their research, because you really have no earthly idea and are maligning people who DO know what they are talking about.
(PS. don't quote me on the squids, I could be mistaken on that)
