A study has found that lipid membranes can be selectively permeable to 
one or the other sugar or amino acid enantiomer. The study used membrane 
models inspired by the membranes of modern organisms, so is not directly 
relevant to abiogenesis. However it still raises the possibility that 
membrane selectivity was the source of chirality in biological 
molecules. One possible issue is does this effect require chiral 
membrane lipids; if so it only move the question of the origin of 
chirality from sugars and amino acids to lipids.
