Reading "The Best American Science and Nature Writing 2011." Really outstanding. 80% through this anthology and all but one essay is very good. The one stand-out as far as not being good -- and it really is a stand-out, as most entries are so very good -- is full of new age fuzzy-speak, but worse, repetitive. It comes to its few insights and conclusions and then finds different ways to rephrase them to fill out its increasingly tedious space. But that's a lot of complaining about very little -- a short essay wedged into a bunch of longer and always good, often outstanding essays.
Also, Six-Legged Soldiers: Using Insects as Weapons of War. Great read. Full of surprises, from tactics of the ancients to the horrors of Japan's Unit 731 to modern day. Enlightening and disturbing.
