ETH 2006 Ideas
From 2006.igem.org
Last years brainstorming: Previous_Ideas

Cellular automata / Quorum controlled behaviour
- Game of Life or other semitotalistic automata
- propagate a pulse in culture
- Predator-prey-veggies (or just predator-prey)
State representation:
- switches and reporters
- cell life (self destruct and regenerate)
Stepping could be done by
- an exogenious signal, so each step is a process converging to a steady state (avoid problem of developing a dynamic system)
- generations
- oscillating system in cells
(Normally cellular automata are stepped synchronously, but it's often not really necessary)
The matrix would not be as regular as in the mathematical models of corse ...
Logic
- A kind of a simple ALU: at least two simple logic functions and a multiplexer
- An implementation of a full-adder: 1-bit adder with carry
- An irreversible switch (lambda phage like)
Notes
Can't find any logic gates except inverters in the registry, looks interesting.
- → because of that, even simplier gates (AND, OR, XOR, ...) are required
Sensing
- acoustic
- pressure
- electric
- magnetic (exists in nature, cf. [1])
- light (BB exists[2])
- temperature (first BBs by 2005 Toronto team [3])
- chemicals
- number of neighbor cells (related to «Game of Life» idea): it seems that another team tried similar in 2004 [4]
- frequency discrimination
- synchronize oscillations among cells (or have emergent synchronous oscillations in the culture)
Agents (sense & act)
- fire squad: get bacteria to find a reaction on the plate and extinguish it
- bacteria sensing high atmoshpere and switching to produce ozon (to refill ozon holes)
- extract sun milk when needed (depending on sun intensity & skin properties :-) )
Limitations to lift
- E. coli can't move (Seems Penn state had moving E. Coli last year: Penn_StateProjectDes)
- need to control growth to stabilize cell culture structures if they are desired
Misc
- optical lenses: program different (light) refraction angles
