Mr. and Mrs. Morrison were on a safari in Africa.
As they were walking through the jungle, a huge lion comes creeping out towards them, ready to pounce.
"Shoot!" Mrs. Morrison screamed to her husband. "Shoot!!"
"I can't!" he yelled back. "I'm all out of film!"
Carl R. WoeseBorn 15 Jul 1928.American microbiologist who recognized the existence of the organisms Archaea as a third domain of life, distinct from the previously recognized two domains of bacteria, and life other than bacteria. On 2 Nov 1977, his identification of methanogens, a form of life dating back some 3.5 billion years, was reported from the University of Illinois. Woese had long studied the evolutionary track of DNA and RNA. In 1976, he was approached by his colleague Ralph Wolfe, who presented a group of methane producing organisms. Woese studied their RNA and recognized their lack of the entire oligonucleotide sequences. Methanogens are found in oxygen-deficient environments, and mostly obtain their energy by reducing CO2 and oxidizing hydrogen, and releasing methane. |
