The Nuremberg Code, which by rights can be called the first bioethical document, was the first case of ethical solution for legal problems. It emerged as a result of dialogue between lawyers and doctors and became the prototype of all modern ethical and legal guidelines in the field of biomedical research, and dialogue itself became the symbol of bioethics. Bioethics, both in theory and in practice, deals with self developing open systems (sciences, social practices), so the dialogue space of bioethics becomes much broader. It is becoming wider not only due to involvement of new actors in the dialogue, but also due to emergence of new content areas in the already existing interactions of bioethics with other scientific disciplines. Which new types of dialogue have emerged in recent decades? How does the dialogue between bioethics and other sciences develop? The search for an answer to these questions is relevant both for determining the role of bioethics in regulating scientific research and for clarifying the limits of bioethics itself. The purpose of this work is to discover the ways in which bioethics can influence scientific research through establishing of bioethical dialogue. For this purpose, the primary types and forms of dialogue initiated directly by bioethics are revealed, and the role of bioethics in interdisciplinary dialogue is clarified by the example of its interaction with law and sociology.
