 Added some stuff concerning the biochem part, since that's my field of expertise. I recently personally felt the problem of the protein folding problem trying to get supercomputer time to simulate a protein I was studying! Also, given that antibody-antigen generation is still extremely faulty I highly highly doubt arbitrary enzyme design will be solved anytime soon, even though great leaps in protein folding have been made.

 THe issue with loose protons is not ib being or not being atoms. Loose protons have no electrons at all, and thus cannot do Pauli repulsion, and thus cannot do regular chemistry - "should" burrow too much into electron density. The former, however, is not true, because loose protons attach themselves to lone pairs and thus get eletrons and thus can do regular chemistry. This duality is the source of the "proton controversy". In water, for instance, lone H+ do not exist and form H3O+ and H5O2+ /(H2O--H--OH2)+.

 I've always heard it described as "parts hydrogen", which seems simple enough. Surprised this isn't yet mentioned in the explanation. [[User:PotatoGod|PotatoGod]] ([[User talk:PotatoGod|talk]]) 19:47, 10 June 2024 (UTC)
 Seriously guys, read the Nørby paper. It's good. It is also irrefutable. p did not originally stand for anything. Or if it did, you will have to explain what q stood for. This is like insisting the a, b, and c in the Pythagorean Theorem must stand for something in some language. It's just factually, provably not the case. We don't have to keep adding speculations about what it might have meant when there is no mystery. [[Special:Contributions/172.70.230.193|172.70.230.193]] 05:57, 13 June 2024 (UTC)

 Protein folding is biophysics (or rather computational biophysics if you’re doing it in a worthwhile way - Alphafold 2 anyone?), I’m genuinely mad about this.

In Season 13, Episode 14, the kids visit a water park and are annoyed that everyone pees into the water instead of going to the toilet, leading to a breakdown of the water quality.

 Is 'depolymerization' in this context referring to means of chemically recycling plastics? As I understand it, we basically just do recycling of thermoplastics at the moment by physically melting them, whereas being able to split a plastic apart into its component monomers would in principle enable a completely closed loop lifecycle for plastics, easing the strain on dwindling oil reserves and landfills and whatnot. Since these are supposed to be important unsolved problems, I feel like it probably is a reference to this, but I'm not a chemist and there may be something else which makes more sense.
