I haven’t had time to read this yet, but it sure looks interesting. A new paper came out across the pond discussing the thermodynamic efficiency of various cellular processes/computations.
An interesting snippet from the abstract:
Here we show that the computational efficiency of translation, defined as free energy expended per amino acid operation, outperforms the best supercomputers by several orders of magnitude, and is only about an order of magnitude worse than the Landauer bound.
Of course, various scientists assure us that selectionism is a failed concept and that no biologist today takes it seriously, right? Oh wait, also from the abstract:
This issue is interesting both from the perspective of how close life has come to maximally efficient computation (presumably under the pressure of natural selection)
No evidence needed – of course it was done by selection! But, try to point out the limits of selectionism, and people cry foul because “scientists don’t believe that anymore.”
