Written by writers who are scientists by training. Each article have references to sources cited, and attempts to relate the scifi in Dune to current known science.

Shows that Dune, and the related series, cover a wide range of “real-enough” science. From genetic selection and engineering, to reconstructive surgery, quantum physics (prescience/ prophesy), biology (sandworms), ecology, planetary science/ astrophysics, anthropology, political science, psychology and neurology (hallucingenics), engineering (stillsuits).

P62. 1960s Russian Institute of Cytology and Genetics: programme to study the genetics of destination by breeding silver foxes for tameness; resultant breed was remarkably dog-like in terms of behaviour.

P68. “when the first Dune book was written in 1965, genetics and the role of deoxyribonucleic (DNA) in the genetic basis of heredity were the hot topics of the day.”
