Robert F. Furchgott

Died 19 May 2009 at age 92 (born 4 Jun 1916).Robert Francis Furchgott was an American pharmacologist who shared (with Louis J. Ignarro and Ferid Murad) the 1998 Nobel Prize in Physiology or Medicine for the discovery that nitric oxide (NO) acts as a signaling molecule in the cardiovascular system. Their combined work uncovered an entirely new mechanism by which blood vessels in the body relax and widen. Nitric oxide (NO), produced by one cell, acts by penetrating membranes and regulating the function of another cell. Nerves and hormones are well known as signal carriers, but this discovery was a totally new signaling principle in a biological system.

Cross-eyed dog

A man took his Rottweiler to the vet and said "My dog's cross-eyed, is there anything you can do for him?"

"Well," said the vet, "lets have a look at him." So he picks the dog up and has a good look at its eyes.

"Hmm," says the vet, "I'm going to have to put him down"

"Just because he's cross-eyed?" says the man.

"No, because he's heavy," says the vet.
