Scientists Edit Human Embryo Genes Again, Reviving Ethical Debate Over Designer Babies
By

The bagel they save for the regulars. Don't skim, savour.
Summary
Scientists have once again edited the genetic code of human zygotes (embryos at the earliest single-cell stage), reigniting the ethical debate that has surrounded human germline editing since Chinese scientist He Jiankui's controversial 2018 experiment. Proponents argue the technology could revolutionize disease treatment, while critics compare it to eugenics and warn it could allow parents to select desirable traits, potentially opening the floodgates to designer babies.
