On June 1^st Organic Matter will be hosting the infamous Tangled Bank (a biweekly collection of top-notch scientific blogging). In preparation I’ve taken the liberty of writing a last-minute piece for inclusion (to be posted shortly) in the soon-to-be-released May 18^th edition of the TB over at the Medical Madhouse. Because the piece I wrote doesn’t fit nicely into any of the existing categories we’ve got, and because I plan to work up some similar pieces of other topics that I find interesting, I’ve taken the liberty of adding a natural history category to the taxonomy. It would just tickle the shit out of me if interested readers felt compelled to write something about their favorite tidbit of natural history in order to fill the ranks of the new category.
