Every so often, I find a paper with a title that's too good not to share. Here's today's edition:
Trapecar M, Vinkovic MK. Techniques for fingerprint recovery on vegetable and fruit surfaces used in Slovenia--a preliminary study. Sci Justice. 2008 Dec;48(4):192-5.
The upshot is that if you want to fingerprint fruit, your best bet is to dust with Swedish Soot. Silver Special powder and cyanoacrylate fuming don't work as well.
You can thank me later.
