One Sunday morning, the pastor...

One Sunday morning, the pastor noticed little Alex standing in the foyer of the church staring up at a large plaque. It was covered with names and small American flags mounted on either side of it.
The six-year old had been staring at the plaque for some time, so the pastor walked up, stood beside the little boy and said quietly, "Good morning, Alex."
"Good morning, Pastor," he replied, still focused on the plaque. "Pastor, what is this?"
The pastor replied, "Well, son, it's a memorial to all the young men and women who died in the service."
Soberly, they just stood together, staring at the large plaque. Finally, little Alex's voice, barely audible and trembling with fear asked,"Which service, the 8:00 or the 9:30?"

Niels K. Jerne

Born 23 Dec 1911; died 7 Oct 1994 at age 82. Niels Kaj Jerne was a Danish immunologist who shared (with César Milstein and Georges Köhler) the 1984 Nobel Prize for Physiology or Medicine. Jerne has provided three important theories of immunology. (1) Natural selection theory of anti-body formation (1955) which initiated modern cellular immunology since the1960s. (2) Somatic generation theory of the generation of antibody diversity (1968) which brought together molecular and cellular immunology in the 1970s. (3) Network theory (1974), which explains a complex system of interactions when the immune system is activated to counteract disease and then is shut down after the need passes. The principles of this theory are beginning to be exploited in prevention, diagnosis and treatment of disease.«
