An international group of scientists has ditched ethical guidelines so that they can grow babies for forty days, for the sole purpose of killing them for research. The International Society for Stem Cell Research issued new guidelines that lift restrictions on certain types of unethical research that manipulate, alter, or destroy human embryos. It wants to remove a 14-day rule for research on human embryos, established in 1979, which stated scientists may only experiment on human embryos up to 14 days after fertilisation. This rule has been the current policy in the United States and generally a scientific standard throughout the world. The new guidelines have removed all restraint, creating the potential for ‘baby in a bottle’ experiments. It also wants to use three-parent human embryos (human embryo with DNA from three individuals), which is currently prohibited, and to allow creating a cell from animal and human cells, characteristic, or tissues.
