eganp··on Is San Francisco about to return to its Bohemian roots?
Detroit is also strongly conformist. But, ever present threat of crime lords 90% of the hold-up. Look what happened when Dan Gilbert go the cops to clean-up a couple blocks of downtown!

This is absolutely it. You can't get the weird, good and bad, unless your cost of living is so low that subsistence can be met with minimal effort. That free time is necessary to do acid and work on the crazy stuff that people don't understand, yet.

I, a millenial that pays $2k/bedroom, am always struck by the portrayals of the 1960s where people in their 20s live 10 to a loft and make rent working a few nights a week at the bar downstairs.

eganp··on The Chiral Puzzle of Life
Your point on complexity is well taken.

I'd just like to recommend against using thalidomide as an example of chiral effects. Rather unusually, thalidomide has a nitrogen atom as its chiral center. As such, it rapidly racemizes (interconverts) at physiological pH. This makes the claim of stereospecific teratogenicity a bit puzzling as it shouldn't be possible to resolve by administering enantiopure thalidomide.

The mechanistic story of thalidomide is a bit complicated. Ultimately the mouse and rat models used couldn't possibly predict teratogencitiy as these models have an amino acid mutation (valine -> isoleucine) that prevents binding of thalidomide to Cereblon, the protein that mediates thalidomide's teratogencitiy [0]. Amazingly, although this story is oft-repeated, its origins are unclear. This is likely the origin of the myth [1], but knowing what we know now these results should be impossible.
