Remember those prizes I promised if you donated to any of the ScienceBlogs DonorsChoose.org challenges? I described the prize for one lucky donor to the evolgen challenge. Now Seed has revealed what they’re giving away to a few lucky contributors to any of the ScienceBlogs challenges. Janet has the lowdown at her blog — the lucky donors will win either a t-shirt, mug, subscription to Seed, or copy of “The Best American Science Writing 2007″. Also, one really lucky donor will win an iPod nano. Go read Janet’s post to learn the details.
