How Space Changes Our Genes and Bodies

A new study looks at how long stays in space affect the human genome, the instruction set for our bodies. Space has microgravity, meaning very little gravity, which changes how cells and genes behave. Astronauts can experience muscle and bone loss, vision changes, and effects on the nervous system. Scientists use a machine called a Random Positioning Machine to simulate zero gravity on Earth and study how genomes organize in space-like conditions. This helps understand the physical role of gravity in gene function and body health during spaceflight.
