【#Tech24H】A research team from the Austrian Research Center for Molecular Medicine and the Ludwig Boltzmann Institute for Network Medicine at the University of Vienna has developed an AIbased "tissue clock" that can predict the biological age of human organs from histological images. Moreover, tissue aging information can also be detected through blood samples. This provides a new framework for understanding the aging process and opens new avenues for disease monitoring and early diagnosis. [ By Zhang Liyan | Tang Ruohan ]
