Heart muscle cells derived from stem cells show remarkable adaptability to their environment during and after spaceflight, according to a new study. The researchers examined cell-level cardiac function and gene expression in human heart cells cultured aboard the International Space Station for 5.5 weeks. Exposure to microgravity altered the expression of thousands of genes, but largely normal patterns of gene expression reappeared within 10 days after returning to Earth. [1] Funny. We learn to crawl. We learn to walk. We run. We learn to fly. Eager to go to the stars. Flying away from home. Exploring the cosmos. We will know things. We will learn. We will reach the end of the cosmos. But only when we go back at home, into that cradle where we first listened to our mother, will we be who we are again… Only when you know where you started from does the destination have a meaning… Father… Are you still there?
