This comment argues for the recognition of ecocide as an international crime, focusing on its contemporary legal relevance and the growing momentum for its codification. Originally coined in 1970 to describe wartime environmental destruction, the term ecocide was framed in parallel to genocide and grounded in the post–World War II development of international criminal law. Although initial legal efforts to formalize ecocide, including proposed conventions and debates during the drafting of the Rome Statute, failed to secure sufficient political support, these early shortcomings have been re-energized by rising environmental consciousness and sustained legal advocacy, particularly by the Stop Ecocide Foundation. Recent developments, including the 2021 legal definition proposed by the Independent Expert Panel and the 2024 amendment proposal to the Rome Statute advanced by Pacific Island nations, reflect a renewed and increasingly actionable international consensus. By examining the conceptual genealogy of ecocide and its doctrinal links to international humanitarian and criminal law, this comment contends that recognizing ecocide as a core international crime is not only a normative necessity but also a legally coherent and pragmatic step. It directly responds to the scale and urgency of present environmental crises and addresses a longstanding gap in the enforcement architecture of international criminal law.

As apex predators, giant otters (Pteronura brasiliensis) are susceptible to the bioaccumulation of heavy metals, particularly in regions where gold-mining contributes to mercury (Hg) pollution. This is the broadest-scale study assessing Hg and selenium (Se) concentrations in the Pantanal. Samples from 10 sites across the Pantanal were analysed using inductively coupled plasma mass spectrometry. We constructed a two-factor generalized additive model (GAM) to investigate the relationship between Hg concentrations in giant otters and their location along river courses in gold-mining areas. To determine the feasibility of merging the dataset from the present study with the dataset of a previous study carried out by our group during 2016–2017, we included the datasets as a factor in the analysis. The GAM results supported the feasibility of merging the datasets. Additionally, we measured Se concentrations due to their potential to mitigate Hg toxicity. Higher Hg levels were found in otters from watercourses near gold-mining areas, with concentrations decreasing downstream, revealing a contamination gradient and the extensive impact of local pollution on wetlands. The highest Hg concentration was recorded in the Bento Gomes River, within a gold-mining area, whereas otters from unconnected sites exhibited lower Hg levels.

Adherence to healthy dietary patterns, including fruits, vegetables and whole grains, is linked to improved health outcomes. However, limited research has explored this association in Latin American populations. This study aimed to investigate the association between adherence to a healthy eating score (unweighted and weighted) and all-cause mortality risk in a Chilean population. This longitudinal study included 5336 Chilean participants from the Chilean National Health Survey 2016 and 2017. Six healthy eating habits were considered to produce the healthy eating score (range: 0–12): consumption of seafood, whole grains, dairy products, fruits, vegetables and legumes. A weighted score was also developed. Participants were categorised into quartiles based on their final scores, with the healthiest quartile used as the reference group. Associations between healthy eating score and all-cause mortality were performed using Cox proportional hazard models adjusted for confounders. After a median follow-up of 5·1 years, 276 (5·2 %) participants died. In the fully adjusted model, compared with participants in the healthiest quartile of the score (Q4), those in the unhealthiest quartile (Q1) had 1·61 (95 % CI: 1·14, 2·27) times higher all-cause mortality risk. A similar association was observed for the weighted healthy eating score (1·52 (95 % CI: 1·03, 2·23)). An inverse trend was observed for both scores (P < 0·05). Sensitivity analyses excluding participants who died within the first 2 years showed consistent results 1·63 (95 % CI: 1·09, 2·42). Individuals with the lowest healthy eating score (unweighted or weighted) had a higher mortality risk compared with their counterparts. A healthy eating score is associated with mortality risk in the Chilean population.

This paper considers what anti-colonial surrealist praxis can provide those of us interested in the nexus of aesthetics and world politics. Thinking beyond the commonly held notion of surrealism as a European cultural movement, I engage with the writings of 20th-century anti-colonial surrealists, namely, Suzanne Césaire, Aimé Césaire, and René Ménil. In doing so, I argue that anti-colonial surrealism is beyond a movement, a selection of methods, a genre or a set of ideas. Instead, I aim to position anti-colonial surrealist praxis as an epistemology that allows us to move beyond the limitations of representation, both by surfacing historical intimacies (rather than gaps) between content and form, while also questioning the demarcation between art and politics. I illustrate my argument’s resonance in the contemporary political moment through an engagement with aesthetic interventions produced by Sai, an artist exiled from contemporary Myanmar. Sai’s absurdist creative interventions and material drawn from in-depth interviews and ethnographic observations allow me to demonstrate the political possibilities of an ‘anti-colonial surrealist praxis’ approach, in its conception of aesthetics as co-constitutive, rather than only representative, of the political.

The European Organization for Nuclear Research (CERN) in Geneva, Switzerland, is renowned for operating the world’s largest particle accelerator and is often regarded as a model of high-profile international collaboration. Less well known, however, is a key episode from the late 1950s, when CERN clashed with the research priorities of similar organizations. The issue centred on a CERN-sponsored study group on controlled thermonuclear fusion, which brought together scientists from CERN member states, as well as representatives from the European Atomic Energy Community (Euratom), the European Nuclear Energy Agency (ENEA) and the US Atomic Energy Commission (AEC). While their meetings succeeded in creating an international network for exchanging reports and coordinating projects to avoid duplication, the initiative failed to establish joint fusion research programmes in Europe. This article explores the reasons behind this outcome to provide insights into intergovernmental power dynamics and scientific competition and how these two factors favoured the creation of a new fusion research institution in the UK, the Culham Laboratory. In doing so, the article contributes to a deeper understanding of the role of science in European integration, while also highlighting that CERN’s involvement in application-oriented research remains an underexplored aspect of its history.

This paper investigates the nonstandard use of first‑person singular pronouns (myself and I) in coordinate constructions, such as John and I or John and myself. Native English speakers frequently disregard prescriptive grammar rules by using subject or reflexive forms in place of object forms in sentences like Give those papers to John and I. The frequency of such nonstandard usage raises questions, such as when and why speakers substitute nominative or reflexive pronouns for object pronouns in coordinate constructions, and what evidence exists for the existence of fixed constructions like X and I or X and myself. To address these questions, the study analyzes data from the Corpus of Contemporary American English (COCA). Findings provide strong evidence for the existence of an X and I construction in that the nonstandard form is common after the coordinator but not before. Evidence for an X and myself construction is weaker, since untriggered reflexives also appear outside coordinate constructions. First‑person singular forms are more likely to appear in hypercorrect and untriggered forms that other pronouns. The research suggests that X and I may be stored in a chunk, possibly due to overgeneralizations resulting from prescriptive corrections during language acquisition.

This CFD study investigates the aerodynamic characteristics of various internal grid patterns of grid fins without missile bodies, focusing on their influence on aerodynamic performance in subsonic flight regimes. Research examines four distinct grid fin lattices through comprehensive numerical simulations at Mach numbers 0.1, 0.3 and 0.5, for varying high angles of attack ranging between 0o ≤ α ≤ +45o. For validation, comparison between current numerical results and a previous experimental study results was carried out (good agreement within 9.8% error). The numerical results reveal that the diamond cell pattern demonstrates increased lift generation but incurs higher drag, while the square pattern minimises drag and pitching moment, favouring weight-efficient designs. The hexagonal grid fin excels in stall delay and post-stall performance, enhancing manoeuverability and stability at the expense of increased pitching moments. The triangular pattern offers balanced aerodynamic performance with high aerodynamic efficiency at lower speeds, making it versatile for various applications. The analysis offers key insights into grid cell pattern’s aerodynamic effects, aiding grid fin design optimisation for improved aerodynamic efficiency and controllability across various flight conditions and high angles of attack.

Long-term results of total aortic cusp replacement such as the Ozaki procedure in paediatric patients have rarely been reported. We describe the 13-year follow-up of a 9-year-old boy with aortic valve regurgitation who underwent total aortic cusp replacement without the need for reintervention. His aortic valve regurgitation is mild with peak pressure gradient of 22 mmHg at the last follow-up.

Air transportation significantly contributes to air pollution, making the reduction of fuel consumption and emissions critical for sustainable development. Continuous climb operations (CCO) have emerged as a promising approach to minimise the environmental impact of aviation, particularly during the climb phase, where fuel burn is highest. This study assesses the efficiency of vertical climb profiles using flight data from departures at Trabzon Airport. The analysis incorporates maximum thrust and maximum rate of climb constraints alongside clean configuration to design CCO profiles. These profiles are compared with actual flight data, revealing that CCO implementation could result in average savings of 5.1% in time, 8% in fuel and 7.5% in HC, 8.8% in CO and 5.8% in ${\rm{N}}{{\rm{O}}_{\rm{x}}}$ emissions. The study highlights challenges in CCO implementation, particularly due to speed regime changes and flight procedure constraints, emphasising the need for enhancements in air traffic management to maximise CCO benefits in complex airspace environments.

Some authors maintain that we can use causal Bayes nets to infer whether $X \to Y$ or $X \leftarrow Y$ by consulting a probability distribution defined over some exogenous source of variation for $X$ or $Y$. We raise a problem for this approach. Specifically, we point out that there are cases where an exogenous cause of $X$ (${E_x}$) has no probabilistic influence on $Y$ no matter the direction of causation—namely, cases where ${E_x} \to X \to Y$ and ${E_x} \to X \leftarrow Y$ are probabilistically indistinguishable. We then assess the philosophical significance of this problem and discuss some potential solutions.

A blastomere containing more than one nucleus is defined as a multinucleated blastomere. In our study, we aimed to investigate the relationship between serum anti-Mullerian hormone (AMH) levels and multinucleated (MLN) embryos, one of the parameters indicating embryo quality, in intracytoplasmic sperm injection (ICSI) cycles. The results of 888 ICSI cycles of patients aged 19–45 years attending an ART (assisted reproductive technology) clinic were retrospectively analysed. Cycles with at least one MLN embryo were defined as the study group (n = 237) and cycles without MLN embryos as the control group (n = 651). Univariate and multivariate logistic regression analyses were used to determine the risk factors affecting the dependent qualitative variables. The effect of AMH levels on multinucleation was found to be a significant risk factor (p < 0.001). One unit increase in AMH levels increases the risk of the presence of MLN embryos by 1.12 times. The mean MLN embryos/total embryo ratio in the group with clinical pregnancy was 0.34 ± 0.18, while the mean MLN embryos/total embryo ratio in the group that did not achieve clinical pregnancy was 0.47 ± 0.3 (p = 0.010). The presence of an MLN embryo has been associated with poor embryo development and ART outcomes. Parameters that can predict the formation of MLN embryos before treatment are crucial for the determination of the pregnancy rate. According to our results, serum AMH levels can be used as a predictive marker for the formation of MLN embryos.

The range of putatively medical animal practices varies widely both functionally and mechanistically. In this article, we argue that the definitions of medicine available in the empirical literature are inadequate for distinguishing genuinely medical practices from other adaptive behaviors. We aim to improve this conceptual landscape by proposing a definition that incorporates both cognitive and functional requirements, enabling finer-grained distinctions across species and behaviors. We apply our definition to the evidence and determine which animal behaviors show a mere difference of degree with paradigmatic medical practices—and should be seen as medicine—and which should be excluded from this nomenclature.

In 1893, the British explorer Frederick George Jackson travelled in the north of the Russian Empire, where he learned lessons—particularly in the areas of diet, transport, and clothing—from the Nenets and Sami people. I argue that his travels in this area influenced both his subsequent Jackson-Harmsworth Expedition (1894–97) and British Antarctic expeditions in the early 20th century, including those led by Robert F. Scott and Ernest H. Shackleton

Studying Jackson’s travels and writings can advance discussions about the role of Indigenous knowledge in British Polar exploration in the late 19th and early 20th centuries.

Based on a new reading of both published and archival materials, the paper also charts some forms of knowledge that Jackson struggled to appropriate—particularly the use of reindeer for transport. In examining his failures, I argue that attempts to write Indigenous contributions into the history of exploration must focus on explorers’ failures as well as their successes—and on forms of Indigenous knowledge that proved difficult to use in other contexts.

Theories of ecological function often appeal to the liberality criterion to evaluate a theory’s adequacy. The liberality criterion requires that a functional description successfully differentiates between functions and nonfunctions. A functional description is considered inadequate if it is excessively liberal or excessively restrictive. I criticize the deference that is shown to the liberality criterion. I present a hypothetical case to illustrate how the application of the liberality criterion needlessly problematizes the four general theories of ecological function. Instead, a theory’s functional description should be considered adequate as long as it produces a better understanding of the complex phenomenon under study.
