Hi, John. It is amazing!!
I would like to highlight the word "constraints" at the caption of the DNA
diagram (http://phys.org/news/2016-06-layer-dna.html)
"The rigid base-pair model is forced, using 28 *constraints *(indicated by
red spheres), into a lefthanded superhelical path that mimics the DNA
conformation in the nucleosome. Credit: Leiden Institute of Physics"
The same word is used by Bob Logan and Stuart Kauffman to relate mechanical
concepts with 'information' (http://philpapers.org/rec/KAUPOA)
Could it have any parallel between these two approaches?

Also, you usually think "DNA" associated with Biological Sciences, but this
research is made at Leiden Institute of *Physics*! Of course, to work
current (complex, innovative) science you must have an interdisciplinary
