  • Normalising transparency

    Brian D Earp, Libby Frith et al.ARTICLEJournal of Medical Ethics2026

    i We adopt the definition used by Nature portfolio journals: 'AI-assisted improvements to human-generated texts for readability and style, and to ensure that the texts are free of errors in grammar, spelling, punctuation and tone.These AI-assisted improvements may include wording and formatting changes to the texts, but do not include generative editorial work and autonomous content creation'. 18 As Hosseini and colleagues 16 note, using the shor…

  • Stem cell-derived embryo models

    Christopher Gyngell, Fiona Lynch et al.ARTICLEJournal of Medical Ethics2025

    Stem cell-derived embryo models (SCEMs) are model embryos used in scientific research to gain a better understanding of early embryonic development. The way humans develop from a single-cell zygote to a complex multicellular organism remains poorly understood. However, research looking at embryo development is difficult because of restrictions on the use of human embryos in research. Stem cell embryo models could reduce the need for human embryos…

  • Disability, Subject‐Dependence, and the Bad‐Difference View

    Open AccessShu Ishida, Mitsuru Sasaki‐Honda et al.ARTICLEBioethics2025

    Philosophers have debated on the “mere‐difference” view of disability, according to which disability as such is neutral in terms of well‐being, just like race and gender. It is contrasted with the “bad‐difference” view, which holds that disability is bad for its possessor even in a non‐ableist situation. We first illustrate how neither view can be sensitive to the diversity of disabled people and their disabilities. Subsequently, we propose an al…

  • The Donation of Human Biological Material for Brain Organoid Research

    Open AccessM Kataoka, Christopher Gyngell et al.ARTICLEScience and Engineering Ethics2024

    Human brain organoids are three-dimensional masses of tissues derived from human stem cells that partially recapitulate the characteristics of the human brain. They have promising applications in many fields, from basic research to applied medicine. However, ethical concerns have been raised regarding the use of human brain organoids. These concerns primarily relate to the possibility that brain organoids may become conscious in the future. This …

  • Animus

    Open AccessJulian Savulescu, Tsutomu SawaiARTICLEJournal of Medical Ethics2024

    We review recent research to introduce human brain organoids into the brains of infant rats. This research shows these organoids integrate and function to affect behaviour in rats. We argue that this raises issues of moral status that will imminently arise and must be addressed through functional studies of these new life forms. We situate this research in the broader context of the biological revolution, arguing we already have the technological…

  • The legal personhood of human brain organoids

    Open AccessM Kataoka, Tsung-Ling Lee et al.ARTICLEJournal of Law and the Biosciences2023

    Research using three-dimensional neural tissues derived from human pluripotent stem cells-known as 'human brain organoids'-has progressed rapidly in recent years. Although related ethical issues have been intensively discussed, legal issues have only been sparsely examined compared with the related ethical issues. In this paper, we explore a fundamental issue concerning the legal status of human brain organoids: whether they can be considered leg…
