Krementsov examines a particular fascination with the dream of immortality and the place of science and fiction in its pursuit in Russia during roughly a decade that followed the country's political revolutions of 1917. It argues that contemporary scientific experiments aimed at the control over life, death, and disease inspired many Russian writers to conduct their own literary experiments with the ideas and techniques offered by experimental biology and medicine, which found expression in both popular-science writings and a new literary genre, science fiction.
