Over the course of just one month in space, engineered human heart tissue got weaker... the findings... offer a useful means of identifying the molecular pathways behind the detrimental effects of spaceflight.
Microgravity can be hard on the body, and astronauts exposed to it have experienced cardiovascular changes... unpicking the effects on the heart of long-duration spaceflight has remained out of reach.
To overcome this challenge, Kim and his colleagues sent engineered heart tissue to the International Space Station for 30 days… they used sensors to monitor strength of tissues' contraction.
The study highlights the importance of understanding how microgravity affects human physiology, particularly the heart, to prepare for future long-duration space missions.
