Machine learning for amino acids to determine protein function and structure
Editorial Comment:  I remember reading Harvey Bialy’s article on “The I Ching and the Genetic Code” in the magazine IO back in the day.  64 codons in DNA to describe amino acids, 64 changes in the I Ching.  The essay is available in the IO Anthology

Editorial Comment:  This is incredibly beautiful and useful work.  Gary Doskas has done something marvelous and (naturally) magical.
PS:  Gary is trying to identify this shape which contains 4 overlapping rhombic dodecahedra

If you recognize it, please contact Gary Doskas or me so that I can refer the information to him.  I already pointed him to George Hart’s Encyclopedia of Polyhedra:
