The ability of natural organisms to selfassemble, self-repair and reproduce in an environment with sufficient nutrients is one of the defining features of life. In this paper, we build on both our own previous work and that of others to demonstrate the feasibility of robotic systems that can assemble functional copies of themselves from either basic sets of(More)
The article describes the technical strategies for clinical cryogenic preservation of low-quality human semen. To compensate for sperm dilution resulting from the use of a cryogenic medium, ejaculated semen was concentrated before freezing by means of continuous-step density gradient centrifugation. Freezing was simplified by employing the carbon dioxide(More)
