This book explores the concept of life assemblages, drawing attention to the diverging ways in which societies share questions of what is a life worth living. In accordance with the urgency, gist and expression of such questions, societies deal with the regulation of new developments and practices in life science research and mobilise available political mechanisms to deliberate them. Seventeen empirical case studies debate themes ranging from population planning, reproductive decision-making, genetic testing and genomics to human embryonic stem cell research and experimental stem cell therapies in Asian countries. The debates outlined also shed light on theoretical conceptualisations of eugenics, biopower, risk signatures, population studies, public deliberation, reproductive choice, bioethics, bionetworking, international science collaboration, public deliberation, research objects and scientific development in countries of different levels of wealth.
