As NASA engineers have found out, space travel can make your genes turn on and off. Almost as soon as an astronaut gets into space, their gene expression looks like fireworks in the night sky. This still happens even when the astronaut is back on Earth, but only temporarily.

NASA engineers have been researching about gene expression and how being in space has affects on the human body.

This is related to engineering because scientists need to know what being in space does to the human body.
