While many ailments are considered terrifying, Lesch-Nyhan is the stuff of nightmares. An extremely rare genetic neurological disorder with no cure, it often compels its victims to self-mutilate, even when they understand that doing so causes them harm. Richard Preston used Lesch-Nyhan as a plot device in his best-selling thriller The Cobra Event, and went on to write a fascinating article about the disease, its sufferers, and its implications for human behavior in the New Yorker.

The Demon in the Freezer An article by the author of The Hot Zone. " The water contained the whole molecules of life from variola, a parasite that had colonized us thousands of years ago. We had almost freed ourselves of it, but we found we had developed a strong affinity for smallpox. Some of us had made it into a weapon, and now we couldn't get rid of it. I wondered if we ever would, for the story of our entanglement with smallpox is not yet ended".
It's not about anthrax, but this piece (by Hot Zone author Richard Preston) from the New Yorker a couple of years ago discusses smallpox, the reasons why we keep samples around instead of getting rid of it, how effective it would be if used as a biological weapon, how prepared we are, etc. etc. Also contains an interesting bit mentioning other threats of anthrax (and this was '99).
