103. How space impacts the body

Discovery Matters

Ever wonder what happens to your body when you leave Earth behind? In this gravity-defying episode, we launch into the weird, wild world of human biology in space. From the first C. elegans in space to the NASA Twins Study to future deep space missions, we have a lot to discuss. Strap in as we float through the science of space adaptation. Spoiler: space may teach us about our Earth-bound health.
