One site I’ve discovered lately that’s damn interesting is Damn Interesting [high hat]. It is, as far as I can tell, exactly as advertised: Short articles on random, but always interesting, stuff.
A few that might be of interest to Gristmillians: A little piece on the Hindenburg disaster, which completely ended what was until then promising and safe development of air ships, and a bit on the latest developments in toilet technology.
And as someone who is highly allergic to cashew nuts, it was gratifying to learn that they are in fact highly toxic.
