So, if you want to go deeper... I think canon does have some focus bracketing with their macro lenses. But those are crazy pricey and you don't necessarily need them. I use lenses from laowa that on canon mirrorless bodies are fully manual but give me 2x magnification and much lighter weight. The other thing you need as mentioned is light. An on-body flash with a fast recycle time and well placed diffusion will give you great shots (check out the AK diffuser).

You can even get good hand-held focus stacking results with a fast flash and a bit of practice.

Good luck! It's an addicting and rewarding hobby.

This article is very poorly written. It conflates protein structure with RNA structure. Proteins are polymers of 20 types of amino acids with comparatively widely varied chemical properties and structures. RNA is a polymer of 4 types of nucleotides with very similar chemical properties and structures. Predicting the secondary structure (structure on a local scale) of RNA is essentially a solved problem on traditional computers and clever but human written algorithms up to several thousand nucleotides.

The novelty here is an iterative increase in complexity in what can be tackled by quantum computing.
