As a right-handed person, I find this deeply offensive and request all left-handed life be destroyed at once!!

That said, would it be possible to make "right-handed" food that is safe to eat, satisfies the psychological urge to consume food in every sensory measure, but still contributes 0 calories?

I thought that sort of how artificial sweeteners work

We have matter-antimatter asymmetry in physics... and now I just learned there's a similar concept in chemistry (one variant frequently occurs in life while the other mirrored variant is rarely found in nature)

Do I understand correctly that Kagan has been working on his part for (more than) 40 years?

Reading Wikipedia it seems he also didn't win another Nobel because the max number of recipients is 3. It's not that unusual that people get the prize a loooong time after their actual work though.

I have to admit that when I read the intro header of the piece on the page, “They made chemistry choose a mirror image,” it struck me as LLM-speak and I immediately lost interest. I have no idea whether the authors used one to draft that phrase, which seems like an innocent summary of their contributions, but somehow I feel like if it were three years ago we would have never seen that in the title.

Does this fall under the Tetris effect?

Does this imply a parity violation (and thus that the weak force must somehow ultimately be in involved in the reaction)?

No, in this case neither isomer is inherently preferred, i.e. if you repeat the reaction you could end up with the opposite isomer, but in each run the symmetry is broken leading to an excess of just one.

(Though what you're saying is not impossible per se, I think I read an experimental proposal a while ago which suggested achieving just that, iirc by using parity violation to generate chiral photons which then initiate some kind of reaction!)

No. Even in the absence of parity violations you can imagine a reaction that has a 50% chance of producing only left handed products and a 50% chance of producing only right handed products. This discovery is more like that.

Chirality is quite interesting!
