NASA Developed a Bioreactor Device to Simulate Reduced Gravity
To simulate the weightless conditions of space and thereby bring the advantages of ISS research to laboratories on Earth, NASA developed a bioreactor device to simulate the effect of reduced gravity. A great deal of bioreactor work being used to study patterns of cell growth could help better explain the ways cancers spread.
