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."

      For the 'standard' rules of the Game of Life, this is probably true. Remember though that the rules are changeable; with most real bacteria you've just got a higher chance of survival at higher densities, or some form of lifespan - each point lasting longer than a single turn, with the state of each turn also affecting the lifetime left and spread per unit.

      David Brin's Glory Season takes the Game of Life a step further - proper competition. You line up your array on your side of the board, and your opponent on theirs; after the Go, no more changes can be made, and the winner is the one who has the most live cells on their side when stability is reached.

      With bacteria, this would need a fair amount of adaptation, and might be hindered by the tendency to clump, but I'm sure that various things like a trigger on overdensity that released a short-lived poison onto the board... clusters that had detached from the main would be more likely to survive this, etc etc.

      You've also got elements of 3D being introduced... thick bacteria, thin bacteria, air transfer rather than direct contact with the next cell... could be restricted by laying the single sheet between two slides...

      It certainly requires a fair bit more innovation than the simple 2D board, but that's only to be expected. It is at least a fun thought experiment; rather than the Game of Life being unlikely, just consider this as simply being a heck of a lot more complicated >:)
