Reading good old stuff sometimes pushes you to the borders of your knowledge. So far, I’ve been learning about Liesegang rings recently. No, nothing close to blingy blingy gangsta jewelry actually. Something that has more to do with chemistry. Liesegang rings are a phenomenon of periodic precipitation resulting in circular patterns that impressed scientists a lot a while ago, to the point it came out not only as a physico-chemical process, but as an explanation for some biological phenomena as well. As far as I can tell read, no unifying grand theory of this Liesegang phenomenon made it completely yet, chemically speaking. The thing is, with regard to biology, it did not really stand as a process of any explanatory power, and it disapeared from the biological jargon.

Update: there is a second post on the subject: go ahead!
There is a post about basics in microbiology at Aetiology (though it is dealing with human commensals only). You may go and check, it’s as interesting as a recent post about Petri dishes‘ history…Makes me remember a professor ten years ago, telling us that ecology of microbes was completely overlooked. It’s amazing to see that, though people tried to look into microbiomes and microbionts, we are still not knowing much about all of this.
