Expanded universal carrier screening (EUCS) entails a population‐wide screening offer for multiple disease‐causing mutations simultaneously. Although there is much debate about the conditions under which EUCS can responsibly be introduced, there seems to be little discussion about its aim: providing carrier couples with options for autonomous reproductive choice. While this links in with current accounts of the aim of foetal anomaly screening, it is different from how the aim of ancestry‐based carrier screening has traditionally been understood: reducing the disease burden (...) in the population. The reasons why the aim of EUCS is presented in terms of ‘autonomy’ rather than ‘prevention’ have not been spelled out in the literature. This paper seeks to fill this gap by considering the morally relevant similarities and dissimilarities between foetal anomaly screening, ancestry‐based carrier screening and EUCS. When carrier screening is performed in the prenatal period, enhancing autonomy appears the most appropriate aim of EUCS, as the alternative of ‘prevention through selective abortion’ would urge women to terminate wanted pregnancies. However, when screening is conducted in the preconception period, carrier couples can avoid the birth of affected children by other means than selective abortion, for instance preimplantation genetic diagnosis. To the extent that this increased control over passing on a genetic disorder raises questions of parental responsibility, it seems necessary that the account of the aims of EUCS is wider than only in terms of enhancing reproductive autonomy.

In this paper I critically reflect on the sustainability potential of biomimetic technologies by focusing on writings of the German philosopher Peter Sloterdijk. Although I agree with Sloterdijk that biomimetic technologies - or, as he calls them, 'homeotechnologies' - offer specific opportunities for a more peaceful co-existence of humans and nature, I will argue that his reflections are based on a series of problematic assumptions. I will conclude by arguing that the 'homeotechnological turn' can be effected only if it is (...) developed within the context of a different ecological ethos from the technocentric ethos that currently dominates our attitude towards nature.

Bowman-Smart and colleagues (2023) argue that techniques to screen and analyze the fetal genome are rapidly evolving, and are sometimes already offered commercially. These new developments will all...

The emerging field of ecological genomics promises to bring about a marriage between ecological and laboratory-based, genomic investigations. In this paper, I will reflect on this promise by exploring how ecology and genomics are integrated in the two approaches that currently dominate this field: the organism-centred approach, focusing individual organisms, and the metagenomic approach, concentrating on entire microbial communities composed of a variety of species. I will show that both approaches have already taken some important steps in bridging the gap (...) between genomics and ecology. Since the introduction of next-generation sequencing methodology in 2007, the organism-centred approach does not need to stick to classical model organisms like Arabidopsis anymore. Instead, it is now able to apply genomic tools to ecologically interesting species as well. The metagenomic approach has been able to give ecology a more prominent place in its investigations, in another way. Contrary to classical microbiology, it does not study microbial communities under controlled laboratory settings, but under nature's own conditions. However, in the marriage between genomics and ecology, genomics still appears to be the dominant partner, especially in the case of the organism-centred approach that continues to study the new ecological models in artificial lab environments. Moreover, the organism-centred and metagenomic approaches employ a gene-centred perspective in understanding critical ecological interactions, thus strengthening a reductionist rather than a holistic approach.

Every field of science, but especially biology, contains particular conceptions of nature. These conceptions are not merely epistemological or ontological, but also have normative dimensions; they provide an ethos, a framework for moral orientation. These normative dimensions, whilst often remaining ‘hidden’ and inarticulate, influence the way in which biologists practice their profession. In this paper, I explore what happens when different versions of these implicit normative frameworks collide. To do so, I will focus on a case study from the field (...) of ecological genomics as it has evolved in one particular country, namely the Netherlands. During an important inaugural meeting, the director of one of the most sizeable Dutch ecogenomics centres gave a presentation in which he introduced the term ‘nature mining’. Part of the audience immediately embraced the term, but others were very reluctant. This mixed response is generally explained as a culmination of growing tension about the future direction of the field: due to new funding demands, a shift had occurred from fundamental research to research more interested in ‘valorisation’.
