π¬ NASA tests human kidney cells in space
NASA sent tiny human "organs-on-chips" into orbit to study human organ responses to space. Researchers placed kidney tissue chips on the International Space Station in May 2019. The experiment analyzed cellular changes under microgravity, comparing space samples to Earth controls. The study showed injury and inflammatory changes linked to aging when exposed to serum. This research could help understand diseases and keep astronauts healthy on future missions. π¬
