NASA twin study results have exciting implications for the 2016 Genes in Space winning experiment.
Recently released results show that, contrary to what was hypothesized, Scott's telomeres lengthened while he was in space. Telomeres are protective caps on the ends of chromosomes and are thought to shorten in response to stress and aging. While Scott's DNA had to be returned to Earth for analysis, Julian Rubinfien's 2016 winning experiment aims to develop methods for measuring telomeric DNA directly in space. If successful this could open the door to directly measuring telomeres in space and health monitoring of astronauts during long-term missions.
