Random Analogies
Information quality
a: Information ~
b: Food
What: I like the analogy. Information and food, as measured in ($/bytes) or ($/calories),are as inexpensive as ever. The problem is that the quality of the information is variable like food. All bytes and calories are NOT created equal. One page of Gettysburg address
is quite different than 1 page of magazine print. Likewise 1000 calories or Fish Oil is
much better for you than 1000 calories of bacon lard.Although the bacon lard does taste
good.

a: Lipids ~
b: the poor relations among biological macromolecules
What: "Researchers are familiar with nucleic acids, RNA, proteins, and maybe even carbohydrates, but usually not with lipids," says Zheng Cui, a biochemist at Wake Forest University School of Medicine. "Lipids are probably the most ignored type of molecules by the entire field of biological sciences, and yet they play a key role in many of the functions of the body." For example, lipids function as both energy stores and signaling molecules, and they literally define cells, separating the intracellular from the extracellular components with an impermeable bilayer."

a: T cell ~
b: specially trained detective
What:
"Each T lymphocyte, or T cell, is like a specially trained detective. The T cell examines the evidence that is exposed by the APC. When specific T cells come into contact with the ragweed pollen fragment on the APC and recognize it as foreign, an army of specialized T cells called "helper" cells (actually TH2 cells) is activated, thus releasing chemicals (cytokines) that stimulate B lymphocytes. B lymphocytes produce IgE antibodies that bind to the allergens (such as the pollen fragment). "
