Bacterial Printing Press

juushin writes "New Scientist has reported that scientists at Harvard University have created a bacterial printing press that can be reconfigured to print complex patterns of bacteria. The technology is reported to have applications in studying biofilms, communication between bacteria (and colonies of bacteria), and the interaction of bacteria and surfaces. Of medical interest, these applications may lead to a better understanding of how to prevent bacterial infections."

bacterial computation

[carcosa30]

This sounds like a good way to study computational properties of bacterial colonies. By printing them like this, perhaps they would be able to get them to behave in ways that would perform useful information processing. It might also end up acting as some sort of "interface" to DNA computation.

Whether we'd be able to get them to behave in reproducible ways would be the question.

Here are some links. The first has some interesting photos of bacterial colonies-- similar to cellular automata, because hey! They are! And the second is a link to an article on bacterial colony computation. Or maybe they're both to Goatse. You won't know until you click.
