How Space Changes Our Genes and Bodies
Humans 2.0From: Universe Today · rewritten for kids by Osmo
Read the story
Scientists study how staying in space changes the human genome and our bodies. Space has no gravity, which affects how our cells work. Long trips in space can cause muscle loss, weaker bones, and vision problems. Researchers use special machines to copy zero gravity on Earth and look at how human cells change without gravity.
Big word
