This is from 2014. Does anyone know if there's been any advances since then on what is discussed here?

This article from 2016 has some peripherally related information: https://phys.org/news/2016-06-riddle-life-single-handedness....

They found that in a racemic mixture, an excess of D or L amino acids results in longer, sturdier polymers that don't break down as readily when exposed to hazards such as hydrogen peroxide, and that amino acids delivered by meteorites were slightly biased towards being L and thus catalyzing longer D nucleotide sequences.

Gerald Joyce continues to work on RNA, although I don't see specific publication on chirality since then as far as I can tell. https://joyce.salk.edu/publications/
