This article analyzes the legal regulation of scientific research in European Union law, examining the challenges and paradoxes the EU faces in this area. Through a systematic analysis of normative and programmatic documents, the crucial influence of EU law on shaping international scientific research standards is revealed. The study highlights the evolution of the European Research Area and the fundamental role of the Horizon Europe program in promoting scientific excellence and innovation. The findings have significant implications for EU research policy and its international cooperation in science and technology." The author applies a complex methodology including analysis and synthesis, structural, formal-legal methods, as well as approaches of scientific deduction and induction. The author argues that EU law has a significant impact on the development of international standards for scientific activity. Despite the absence of imperative supranational competence in the field of science, the EU has facilitated the formation of subsidiary mechanisms for funding and supporting scientific activity, leading to the establishment of sustainable institutions and mechanisms within the European Research Area and EU program systems such as “Horizon Europe”, which has resulted in a substantial evolution of standards for scientific activity. The author states that this primarily concerns scientific ethics, multiculturalism and non-discrimination, the evolution of views on transnational research, and the formation of a sustainable regime for funding and evaluating scientific projects.
