Oh, this will be fun!
Tara Smith, proprietess of Aetiology, is kicking off a new Carnival this Thursday:

One, the post must focus on a microbe–bacteria, parasite, virus, fungus, etc. Prokaryotic or eukaryotic, we don’t discriminate. The posts can be light-hearted or serious, research-heavy stuff.

Lots of these little tykes board the Friday Ark every week and we just don’t pay enough attention to them.

If you have submissions get them in and, submission or not, plan on a fun read this Thursday and every other Thursday following.
