Daniel Nathans

Died 16 Nov 1999 at age 71 (born 30 Oct 1928).American microbiologist, corecipient of the Nobel Prize for Physiology or Medicine in 1978 (with American Hamilton Othanel Smith and Swiss scientist Werner Arber). The winners were cited for their discovery and application of restriction enzymes, which provide the "chemical knives" to cut genes (= DNA) into defined fragments. These may then be used (1) to determine the order of genes on chromosomes, (2) to analyse the chemical structure of genes and of regions of DNA which regulate the function of genes, and (3) to create new combinations of genes. Thus new avenues are opened to study the basic problems in developmental biology; and in medicine, to help the prevention and treatment of malformations, hereditary diseases and cancer.

Cowboy Boots

A lady went into a bar in Waco and saw a cowboy with his feet propped up on a table. He had the biggest boots she'd ever seen.
The woman asked the cowboy if it's true what they say about men with big feet are well endowed.
The cowboy grinned and said, "Shore is, little lady. Why don't you come on out to the bunkhouse and let me prove it to you?"
The woman wanted to find out for herself, so she spent the night with him.
The next morning she handed him a $100 bill.
Blushing, he said, "Well, thankee, ma'am. Ah'm real flattered. Ain't nobody ever paid me fer mah services before."
"Don't be flattered. Take the money and buy yourself some boots that fit."
