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.

I saw a lot of channels that sprung to mind already posted. But I want to strongly recommend Thomas Shahan for super chill bug photography and mellow voice overs. Worth checking out even if you're not into macro photography.

I also have a V2.4 and it's the most reliable printer I own. It's the second printer I built and the third I've owned. And having built it from scratch, I know if anything breaks, I can fix it. I added an in-chamber carbon filter, a mod that let's me probe the bed with the nozzle itself, and some custom designed magnetic attachments for the side panels. Oh and a kinematic bed mod -- this let's the bed expand with heat while keeping the center in the same spot.

It's fantastic and I regularly print PLA, PETG, and ABS. I do like tinkering, but I will not touch this one because it's such a reliable workhorse. The one last mod I would contemplate is a way to wipe the nozzle automatically.

My betting is he'll relax tariffs on companies if they pay him.

It's not super clear from the graph alone what's going on here so Iwanted to add some context.

1960 is when Australia fluoridated their water supply. So the data show that no matter how old you were when it happened, it cut the number of decayed, filled, or missing teeth per person in half.

Wash your print surface with dish soap and water and dry with a paper towel or fresh towel. Avoid touching or contaminating the surface once clean and dry.

If that doesn't work, get some magigoo

"Chase" is kind of a strong word. Still cool tho.

Those are a lot of fun to play with! Glad you got it working! Textured PEI sheets are great for PLA in general. Usually a good wipe with isopropyl alcohol before a print works to keep the adhesion strong. I find every once in a while actually washing and scrubbing it with dish soap and hot water is needed to refresh the PEI surface.

There's nothing stopping anyone doing the same with lemmy posts though is there?
