The term may convey a pejorative connotation that the advocate is driven by political, ideological, financial, or other unscientific motives. The term cargo cult science was first used by the physicist Richard Feynman during his commencement address at the California Institute of Technology, United States, in 1974, to negatively characterize research in the soft sciences (psychology and psychiatry in particular) - arguing that they have the semblance of being scientific, but are missing "a kind of scientific integrity, a principle of scientific thought that corresponds to a kind of utter honesty". Check out their first sentence: " Life is mostly composed of the elements carbon, hydrogen, nitrogen, oxygen, sulfur and phosphorus. Although these six elements make up nucleic acids, proteins and lipids and thus the bulk of living matter, it is theoretically possible that some other elements in the periodic table could serve the same functions." This would be news to my freshman biology 101 professor who taught that the bulk of living matter was composed of water and carbohydrates. If you read the paper, they talk a lot about impurities in the salts and reagants. (!??!) They talk a lot about how you can grow this bacteria by feeding it arsenic and how the arsenic is assimilated into its biomolecules. They analyze lots of extracted fracionated nucleic acid. As for showing that the arsenic actually replaces the phosphorus in the DNA helix.......not so much. Their evidence for this is weak and cold fusiony. I quote: "Show me the money!" and: "Where's the beef?" I can only conclude that this research is motivated by a political hype-driven agenda to get funding during the Great Recession. This isn't sound science, it's press conference science. I don't really blame them, things are tough all over and NASA needs money to conduct their important work. It's just that you can only yell "Wolf!" so many times. ------------------- If you write the word "monkey" a million times, do you start to think you're Shakespeare? (SW) Phil Whitmer ------------------- There is a big difference between "junk science" and science which is incomplete, or published too early, or even of generally marginal quality. In the case of this recent work, the hypothesis is sound and the techniques used are reasonable. Certainly, there is reason to suspect that more work should have been done before publishing (although that is far from certain at this point). I don't know how this will all shake out in the long run. I'm sure that others will be pursuing similar work, and applying additional tests. In any case, having read the paper, I don't think this work can fairly be called "junk science". At worst, it is incomplete. Chris Received on Wed 08 Dec 2010 12:07:03 PM PST |
