Photographer

A photographer for a national magazine was assigned to take pictures of a great forest fire. He was advised that a small plane would be waiting to fly him over the fire.
The photographer arrived at the airstrip just an hour before sundown. Sure enough, a small Cessna airplane was waiting. He jumped in with his equipment and shouted, "Let's go!" The tense man sitting in the pilot's seat swung the plane into the wind and soon they were in the air, though flying erratically.
"Fly over the north side of the fire," said the photographer, "And make several low-level passes."
"Why?" asked the nervous pilot.
"Because I'm going to take pictures!" yelled the photographer. "I'm a photographer, and photographers take pictures!"
The pilot replied, "You mean you're not the flight instructor?"

Methanogens

In 1977, the identification of methanogens, a form of life dating back some 3.5 billion years, was reported by scientists at the University and Illinois. Microbiologist Carl R. 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. He discovered the organisms were so different from bacteria, they deserved their own branch of the family tree as the third domain of life, Archaea. Methanogens are found in oxygen-deficient environments, and mostly obtain their energy by reducing carbon dioxide and oxidizing hydrogen, with the production of methane.
