Bruce Nathan Ames

Born 16 Dec 1929. American biochemist and molecular biologist who developed the Ames test that is an indicator of the carcinogenicity (cancer-causing potential) of chemicals. It measures the rate of mutation in bacteria after the introduction of a test substance. His research led to a greater appreciation of the role of genetic mutation in cancer and facilitated the testing of suspected cancer-causing chemicals. He also developed a data base of chemicals that cause cancer in animals, listing their degree of virulence. In 1997, Ames was one of team of UC Berkeley scientists who discovered the link between low levels of folic acid, an essential nutrient, and breaks that occur in chromosomes and DNA. These breaks could lead to cancer and other diseases.

Cheerleaders Vs. St. Peter

A high school cheerleading squad were in a bus that shot off a cliff killing all onboard... Don't laugh yet! 
When they got to heaven they were met by St. Peter at the gate.
He asked the first girl if she had done anything with any boys, and she said to St. Peter that she had held a boys hand, so St. Peter told her to wash her hands in the holy water before entering heaven. 
St. Peter then asked the second girl the same question, and she said she had kissed a boy, so Peter told her to wash her lips in holy water before entering heaven. 
Then Peter noticed two farther back in line girls arguing over their position in line. 
Peter asked the girls what was going on, and the one girl said to him, "I'm not gargling that after she sits in it."
