Multicellular artificial NN architectures show computational problem solving

A good TLDR on Twitter by @NikoMcCarty (which is how I first came across this):

"Mixtures of engineered bacteria were able to:

- Identify if a number is prime

- Check if a letter in a string is a vowel

- Determine the max number of pieces of a pie obtained from n straight cuts.

Answers are printed by expressing fluorescent proteins in different patterns."
