You know, there was a sneak peek feature in the web site once, but that went on for a batch of the new microbes that were soon to be released and after they were, they took down all that stuff and never let the preview feature stay...

Of course, not counting our good nonpathogenic microbes! (but they are still just as cute!)
We may be gone, but the history is still here.
