Could we live forever in Outer Space?
During my senior year in high school my AP Physics teacher would occasionally inform the class on new
and exciting things happening in science. One of which being NASA’s experiment with twins and
telomeres. I thought it would be fitting to write a blogpost on it.
To sum things up, a pair of twins was monitored for a year while one was in space and the other on Earth.
The results would help improve and prevent health risks associated with space flight. Things like gene
expression and the performance of the immune system were monitored. To me, the most interesting thing
discovered over the year was the change in telomere length. In the article telomeres are described as
“biomarkers of aging at the end of chromosomes.” The twin in space (Scott) was found to have longer
telomeres that returned to average length after returning home, while the twin on Earth (Mark) was found
to have stable telomeres. This information certainly is the starting point to more research and more
information. I think it is safe to joke that the increase in telomere length in space means immortal life (in
