A father and son went fishing...

A father and son went fishing one day. While they were out in the boat, the boy suddenly became curious about the world around him. He asked his father, "How does this boat float?
The father replied, "Don't rightly know son." A little later, the boy looked at his father and asked, "How do fish breath underwater?"
Once again the father replied, "Don't rightly know son." A little later the boy asked his father, "Why is the sky blue?"
Again, the father replied. "Don't rightly know son." Finally, the boy asked his father, "Dad, do you mind my asking you all of these questions?"
The father replied, "Of course not, you don't ask questions, you never learn nothin'."

Prions

In 1997, American biology professor Stanley B. Prusiner won the Nobel Prize for medicine for discovering “prions,” described as “an entirely new genre of disease-causing agents.” The name means “proteinaceous infectious particle.” Prions cause brain diseases such as BSE (Bovine Spongiform Encephalopathy or “mad cow disease”); the human variant Creutzfeldt–Jakob disease; kuru among some peoples in New Guinea; and scrapie in sheep and goats. Prions are too small to be seen with normal microscopy. They are self-replicating, but contain no nucleic acid. Prions are highly resistant to destruction or denaturation by common chemical and physical agents such as disinfectants, formalin, heat, UV or ionizing radiation. Inceration of infected tissues requires a temperature never below 900ºF for four hours.«
