Space-bound heart tissue to aid aging and long-flight studies
Johns Hopkins Medicine researchers are collaborating with NASA to send human heart "tissue-on-a-chip" specimens into space as early as March. The project is designed to monitor the tissue for changes in heart muscle cells' mitochondria (their power supply) and ability to contract in low-gravity conditions. The tissue samples will be launched into space aboard SpaceX CRS-27, a resupply miss
