The Iowa Academy of Science has released its summer newsletter online, and is available here (.pdf).
There’s a lot going on for scientists and the science-interested at all levels (students, teachers, researchers), so for the Iowa folks (or, those of you in other states who are just looking for some good ideas), if you’ve not already checked them out or have a membership, give them a look (their homepage is http://www.iacad.org/). They also have new programs focusing on science education for the general public, which I know is an interest for many readers as well.
