Recrod thermophile, with references

This is, once again, proof that it's easier to print than to
retract...feathers in the wind, so to speak.
I'm working entirely off memory, so hopefully some other posters will
provide the appropriate references (or call Barbara Hemmingsen at San Diego
State University, she know's this by heart). Several years ago a group of
microbiologists working on hydrothermal vents at extreme depths published a
paper claiming that they'd discovered this "hyperthermophile" that could
live temps over 200*C. Naturally the press went wild with this story and it
made it "scientific fact." What is usually not told is that shortly
thereafter a group of microbiologists reviewing the study and attempting to
replicate it discovered that the experimental design was riddled with errors
and that they had not done the proper controls. They had, in fact,
discovered nothing. What they were seeing was an artifact of a poorly
designed experiment. Unfortunately, the press didn't jump on the bandwagon
of the new findings and even today textbooks reference this imaginary
hyperthermophile as fact.
I always get a chuckle when I see references to this imaginary organism...a
lesson in science and the press.
