Virtual twins and the future of human developmental biology (opens in new tab)

Human development begins with a zygote, yet how this cell forms complex tissues remains a mystery. Progress has been limited by ethical constraints and scarce biological materials. Advances in stem-cell models and virtual twins are now transforming research, healthcare, and our understanding of development. Collaboration among scientists, ethicists, and policymakers is essential to responsibly advance these tools. The Virtual Human Development consortium will bridge experts to co‑develop a re...
