Initial Twin Study Released

NASA has released preliminary results from their Twin Study comparing identical twin astronauts Scott and Mark Kelly following Scott Kelly’s long-duration mission on the International Space Station. Results unexpected showed changes in gene expression, DNA methylation and other biological markers. The caps on the ends of Scott Kelly’s telomeres grew longer during his space flight (returning to normal after landing), which was the opposite of the expected results. Full results of the study are expected to be released over the next few years.
