Science reveals to us the mysteries that lie around us and also within us. Nature and we as part of it hide many strange phenomenons. A recent study by Nasa shows that changes take place in genes during the time spent in Space. Once back on earth, some of those changes persist before going back to how they were initially.

Nasa’s study on Twins further explains that DNA methylation which is responsible for turning on and off the genes, increases when in space. What is amazing is the fact that going into a different zone alters things in our gene. The scientist conducting the research on twins in space, Dr Chris Mason of Weill Cornell Medicine explains that the changes that happen in the genes are almost like an explosion taking place.



The experiment became possible due to Mark and Scott Kelly, both Nasa astronauts; Scott was sent into space for 11 months between 2015 and 2016.

The genetic studies reveal that Scott Kelly’s telomeres grew longer than Mark. Telomeres are structures at the end of chromosomes that protect the DNA structure from deterioration.

This comprehensive study dives into physiology, the effect on heart and brain due to microgravity. The study investigates how our reasoning and perception alter due to space travel. Another fascinating study is also done on bacteria in the gut that also shows changes during space travel.
