Perturb the organism; what “diseases” can it get?

Can you give other perturbation that will “heal” it?

Can one evolve a rule that is resistant to perturbation?

One-bit perturbation

Roadmap

Genetics

Take various evolved systems

Disease

Visualize the effect of perturbation at different stages
[ Consider single-cell perturbations + multicell ] [ Consider perturbations at multiple timesteps ]
[Look at whether these are maximally evolved systems, or not] [ maximally evolved will probably be more sensitive ]
Measure the effect on lifetime of perturbations [ histogram ; change in “life expectancy” (aka mortality curves) ] [ e.g. plot mean life ; plot quantiles ; vs. various features of perturbations ]
Try to classify perturbations (e.g. feature space analysis) [ dendrograms ]
What is the cascade of perturbations at subsequent steps (progression of diseases) ( cascading failures ) [ simple plot: number of changed cells vs. time after perturbation ]
What effect on longevity do perturbation at different stages have? [ Could we get a mortality curve that is a Gompertz distribution? ] [ Materials/GompertzMakeham.nb : Casey Handmer ]

Therapy

Is there a subsequent perturbation or pattern of perturbations that heals the system? [ ~ Maxwell’s demon ]
( “Fundamental problem of medicine is to beat CI” )
[ Is the best way to get back on track just to start again? ] [ Can longevity work, or is a new generation the only solution? ]
Pipeline : diagnosis [what features of the behavior tell us what therapy to use? ] ⟶ therapy

Enhancing health

Can you make perturbations that will make the system live longer? (But not get a tumor)

[Larger genomes]

Evolve for robustness [ i.e. have a fitness function that gets to a lifetime even if there are perturbations ]
How do genome variations affect “diseases”? [ Simplest case: look at different genomes with identical phenotypes. How do those different genomes because under perturbation? ]

[Perturbations of genomes] [BioEvol2-26-... ]

Lifetime variation purely with perturbations to genome
[ Variations in other properties by varying genomes : are there Gaussian distributions? ]

Explainability / reductionism

​

Medical research practice

[ Clinical trials ] try various therapies on various perturbations (/ genetic perturbations) on a sample ; then: what happens in a larger sample?
[If the outcomes were tightly constrained in the test, what does that imply for deployment?]
[ Theory of diagnosis ]
[ Failure of therapies ]
Can a therapy work on a large part of the population and fail on some ... or work for a while, and then fail

Large Genomes

k=10

I.e. there’s enough “noncoding genome” that random mutations probably don’t matter
