Bioethics is a branch of applied ethics that studies the ethical implications of advances in the life sciences and biotechnology, including topics such as genetic engineering, enhancement technologies, and the use of reproductive technologies. It is a multifaceted field, drawing on elements from many other disciplines such as philosophy, medicine, law, and public policy to ask questions about the moral and ethical implications of scientific and technological developments. Bioethicists often consider the potential benefits and harms of technologies, and strive to identify the principles and values that should guide decision-making in the life sciences.
