This paper explores the philosophical and practical implications of the natural versus synthetic distinction in chemistry. I consider several interpretations of the term natural as pertaining to substances, and conclude that at its core, naturalness is best understood as a statement about material origin. The analysis reveals that calling a chemical substance natural risks committing a category mistake. The descriptor can only be coherently applied to samples of a chemical substance, not to a chemical substance as a set. Even in the case of samples, the utility of the term is limited. Care must be taken to avoid unwarranted implications.

The research programme 'basal cognition' adopts an evolutionary perspective for studying biological cognition. This entails investigating possible cognitive processes in 'simple'-often non-neuronal-organisms as a means to discover conserved mechanisms and adaptive capacities underwriting cognition in more complex (neuronal) organisms. However, by pulling in the opposite direction of a tradition that views cognition as something that is unique to neuronal organisms, basal cognition has been met with a fair amount of scepticism by philosophers and scientists. The very idea of approaching cognition by way of investigating the behaviour and underlying mechanisms in, say, bacteria, has been seen as preposterous and harmful to both cognitive science and biology. This paper aims to temper such scepticism to a certain degree by drawing parallels with how the evolution of 'development,' another loaded concept that refers to a not-so-easily definable, contested bundle of phenomena, has been fruitfully approached in Evolutionary Developmental Biology (Evo-Devo). Through this comparison, we identify four promising features of the basal cognition approach. These features suggest that sweeping scepticism may be unwarranted. However, each of them comes with important epistemic cautionary notes that should not be disregarded. By presenting these twofold considerations as potential ways to integrate a fully evolutionary perspective into basal cognition, this paper seeks to provide clarity and direction for the advancement of this research programme.

Ulrich von Hutten (1488-1523), a renowned sixteenth-century German humanist, documented the symptoms of the epidemic that swept through Europe starting around 1495, commonly known as the French Disease. While it has traditionally been associated with venereal syphilis, Dutch tropical physician Willem F. R. Essed proposed in 1933, largely unnoticed to this day, that this new disease might instead be tropical yaws. This study establishes a clear link between Hutten's reported symptoms and yaws, especially in its secondary and tertiary stages. The skeleton discovered in 1968 on Ufnau Island in Lake Zurich where Hutten died and was buried, exhibits distinct bone manifestations of ancient treponematosis with a pattern more consistent with yaws than syphilis. Furthermore, the correspondence between Hutten's main symptoms and the lesions observable on the 1968 skeleton further confirms the identification of these human remains. The historical evidence of yaws significantly contributes to our understanding of this early modern epidemic.

This article discusses early modern North Indian ways of expressing how barrenness could be mapped onto a woman's maternal identity. Scholars have engaged with the historical evolution of women's identities, focusing overwhelmingly on their economic and political potential. This article is the first to use medical and erotological sources from the seventeenth and eighteenth centuries to study women as procreative agents, and the socio-sexual anxieties prompted by infertile female bodies. Through a critical study of a wide range of medical material, I demonstrate that by the eighteenth century, several transformations in medical discourses can be mapped onto textual transmissions from Sanskrit (and Braj Bhasha) to Persian, as well as between competing but conterminously flourishing medical paradigms, Ayurveda and Yunani. While cures for childlessness have a much longer history, a new genre of 'anonymous' sources, particularly focused on the sexual diseases of men and women emerged in early modern North India. Lastly, my comparative methodological approach to different textual genres will complicate our understanding of early modern medical episteme and its intended audience.

Background: Making appropriate end-of-life decisions in the intensive care unit (ICU) requires shared interprofessional decision-making. Thus, a decision-making climate that values the contributions of all team members, addresses diverse opinions and seeks consensus among team members is necessary. Little is known about religion's influence on ethical decision-making climates. Therefore, this study aimed to examine the association between religious belief and ethical decision-making climates.

Methods: The study was a cross-sectional analytical observation study as a part of the prospective observational DISPROPRICUS study. A total of 2,275 nurses and 717 physicians from 68 ICUs representing 12 countries in Europe and the US participated. All participants were asked which religion (if any) they belonged to and how important their religion (if any) was for their professional attitude towards end-of-life care. Perceptions of ethical decision-making climates were evaluated using a validated, 35-item self-assessment questionnaire that evaluates seven factors. Using cluster analysis, ICUs were categorised into four ethical decision-making climates: good, average (with nurses' involvement at the end of life), average (without nurses' involvement at the end of life) and poor.

Results: Of the 2,992 participants, 453 (15%) were religious (had religious convictions and found them important or very important for their attitude towards end-of-life care). The remaining 2,539 were non-religious (i.e. had religious convictions but assessed that they were not important for their attitude towards end-of-life care). When adjusting for country and ICU, the overall perception of the four ethical climates was associated with religious beliefs, with non-religious healthcare providers having more positive perceptions of the ethical climates compared to religious healthcare providers (p < 0.01). Within good climates, non-religious healthcare providers rated leadership by physicians (p < 0.01), interdisciplinary reflection (p = 0.049) and active decision-making by physicians (p = 0.02) as more positive compared to religious participants. In poor climates, religious healthcare providers had a more positive perception of the active involvement of nurses (p = 0.01). Within the other climates, no differences were found.

Conclusions: Overall perceptions of ethical decision-making climates were associated with religious beliefs, with non-religious healthcare providers generally having a more positive perception of the ethical climates than religious healthcare providers.

The analysis of citation flow from a collection of scholarly articles might provide valuable insights into their thematic focus and the genealogy of their main concepts. In this study, we employ a topic model to delineate a subcorpus of 1,360 papers representative of bioethical discussions on enhancing human life. We subsequently conduct an analysis of almost 11,000 references cited in that subcorpus to examine quantitatively, from a bird's-eye view, the degree of openness of this part of scholarship to the specialized knowledge produced in biosciences. Although almost half of the analyzed references point to journals classified as Natural Science and Engineering (NSE), we do not find strong evidence of the intellectual influence of recent discoveries in biosciences on discussions on human enhancement. We conclude that a large part of the discourse surrounding human enhancement is inflected with "science-fictional habits of mind." Our findings point to the need for a more science-informed approach in discussions on enhancing human life.

Research on second language (L2) speech learning suggests that incidental perception training can lead to the establishment of non-native phonological categories. The present study contributes to this line of enquiry by investigating how this training is mediated by individual differences in working memory capacity and domain-general auditory processing abilities. In our study, 130 native British English speakers without prior knowledge of Portuguese were randomly assigned to trained or untrained conditions. All participants completed a visual digit span task and an auditory processing test battery. We observed improvements from pretest to post-test in production only, but since both groups improved, these gains cannot be attributed to the incidental perception training. The analysis of the ID measures further confirms the important role played by auditory processing abilities in L2 speech learning. However, more research is needed to better understand the role of incidental perception training and the mediating role of cognitive aptitudes.

In 2023, thousands of young Norwegian physicians joined an online movement called #legermåleve (#doctorsmustlive) and shared stories of their own mental and somatic health issues, which they considered to be caused by unacceptable working conditions. This paper discusses this case as an extreme example of physicians' and healthcare workers' suffering in late modern societies, using Vosman and Niemeijer's approach of rethinking care imaginaries by a structured process of thinking along, counter-thinking and rethinking, bringing to bear suffering as a heuristic device. Thinking along, taking the physicians' stories and arguments literally, reveals an image of an unbearable workload. Counter-thinking resituates their suffering within the broader conditions of late modernity, suggesting that the root cause may lie not in the quantity of the workload itself but in its qualities and in its perceived threat to their integrity as caregivers through epistemic and moral injury and an inability to respond to this threat. In rethinking, the ambiguity of suffering- its dual potential as both a constraint and an opening- becomes central. Following the physicians' own interpretations and the solutions emerging from this framing, both their suffering and that of their patients could paradoxically be exacerbated by further decentering physicians and reinforcing utilitarian, data-driven approaches. However, staying with their suffering and reinterpreting its causes opens possibilities to leverage critiques of medicalization at large and of their own suffering in particular, challenging the assumption that the weight of care must always grow heavier. From this reframing, I argue, it is possible to reclaim and reimagine care and the clinical space as a nexus of epistemic and moral privilege, recentering response-ability both relationally and socially.
