This paper introduces Bioethics-in-Science (BiS), a novel methodological approach entangling bioethical inquiry directly within scientific practice. Drawing inspiration from Van Rensselaer Potter's original vision of bioethics as a collaborative bridge between biology and ethics, BiS represents a community of practice aimed to contribute to bioethical inquiry in three key ways. First, it reframes the relationship between ethics and science by treating scientific practice as inherently value-laden and recognizing scientists’ relevant ethical expertise. Second, it develops methods–including ethics notebooks, collaborative workshops, and conceptual mapping–that facilitate a shift from mere external evaluation towards continuous ethical deliberation within research environments. Third, it demonstrates how bioethical inquiry can actively contribute to improving scientific practice through the co-creation of knowledge and values. Through case studies from synthetic biology, neurodiversity research, and proteomics, we illustrate how BiS arose from and operates in practice and examine the challenges of crossing disciplinary boundaries. As such, we position BiS as offering a pathway for bioethical inquiry to move beyond its peripheral position vis-à-vis the sciences and engage meaningfully with the normative dimensions of scientific knowledge production instead, ultimately contributing to both better ethics and science.
