The summary is (as far as i understand) :
* They have shown that magnetic surfaces can prefererentially crystalise one handed form of an RNA precursor
* The mechanism involves electron spin interacting with the chirality of the molecule
What was not clear to me was whether they have shown that one of the handed forms would be more frequent than the other.

- gilleain 3y agoedit: my bad, i should yave read further - the suggestion is that the location on the Earth'a surface could influence the surface chirality. Well if you have a 'left handed' surface and a 'right handed' surface then the problem has just shifted to the molecule to the surface. To put it another way - what drives the asymmetry of the surfaces?
