The human heart shows signs of ageing after just a month in space
24 September 2024
Nature News covered research co-authored by Johns Hopkins BME professor Deok-Ho Kim, which sent iPSC-derived engineered human heart tissue (“heart-on-a-chip”) to the International Space Station for 30 days. The team observed weakened contractile strength, irregular beating, and aging-like molecular signatures under microgravity; the work was published in PNAS (Mair et al., 2024; doi: 10.1073/pnas.2404644121).
