Psychedelic treatment with psilocybin is receiving increased attention following clinical trials showing it may help treat end-of-life anxiety, depression, and several other conditions. Despite this, physicians may be reluctant to prescribe psilocybin and carry out psilocybin treatment because of the stigma surrounding psychedelics and the potential for medical malpractice liability. This paper explores whether psilocybin treatment gives rise to a risk of medical malpractice liability for physicians. Following an overview of psilocybin treatment and its regulatory regime in Canada, exploratory vignettes are used to highlight the relevance and limits of malpractice claims. This paper argues that the lack of established medical standards, standardized training, and credentialing contribute to liability risks surrounding psilocybin treatment. More clinical trials, meta-studies of research analyses, and knowledge sharing will help to develop training programs and medical standards of practice to better realize psilocybin’s potential.

Global efforts to combat micronutrient deficiencies have often focused on assessing nutrient intakes and supplies(1,2), yet no studies have explored the role of crop selection and land suitability to tackle these deficiencies. This study aims to bridge this gap using existing estimates of global prevalence of iron(3) and zinc(4) deficiencies to identify crops with the highest potential to mitigate these deficiencies. Using the USDA food composition database, we established nutrient profiles for 37 widely cultivated crops, focusing on their iron and zinc content per 100 grams. To evaluate these crops’ effectiveness to meet nutrient requirements, we compared compositions to Harmonized Average Requirements (H-ARs) for women of reproductive age (WRA), a group particularly vulnerable to micronutrient deficiencies. The H-ARs account for variations in nutrient absorption and bioavailability(5). For each crop, we calculated the percentage of the H-AR met by 100 grams of iron and zinc content. This percentage was adjusted for the global prevalence of iron and zinc deficiencies by introducing deficiency weighting—multiplying each crop’s nutrient contributions by the global prevalence of iron and zinc deficiencies. The result was a deficiency-weighted nutrient score for each crop. Soybeans scored highest at 61.67, followed by cowpeas (50.30), pearl millet (33.69), and Phaseolus beans (31.33), indicating their strong potential to address global iron and zinc deficiencies. Next, we integrated these nutrient scores with global land suitability and yield potential data from the Global Agro-Ecological Zones (GAEZ) database to map regions most suited for growing these nutrient-dense crops. On average, our findings show that Tonga is the most suitable country for soybean cultivation, with a potential yield of 3.77 tons per hectare (tons/ha), Uruguay for cowpeas (2.82 tons/ha), Lithuania for Phaseolus beans (3.93 tons/ha), and Guinea-Bissau for pearl millet (3.87 tons/ha). Through multivariate clustering, we linked global deficiency patterns with yield potential across various regions. Countries such as those in the Caribbean, Eastern, Western, and Middle Africa, and Southern and Southeastern Asia emerged as priority regions where the production of these crops would be most beneficial to combat iron and zinc deficiencies. The results provide valuable insights to align agricultural land use practice with nutritional requirements, particularly in regions with high iron and zinc deficiency prevalence.

Alisha Sijapati and Erin Thompson’s article “Making a market for ‘The Art of Nepal’: Tracing the flow of Nepali cultural property into the United States” makes a series of unsubstantiated claims about the nature and scope of the Nepali antiquities market in the 1950s and 1960s based on the authors’ research of a single 1964 exhibition of Nepali antiquities in the United States. This critical response will contest these claims by examining the broader Nepali antiquities market as it existed prior to 1970, particularly within Nepal and in South Asia, while also locating the authors and their claims in the context of the recent repatriation campaign by Nepali activists. Finally, the response will conclude that if there is to be an ethical turn in voluntary repatriation, there must be greater consideration of contexts beyond the West and a refocusing of provenance research beyond Western collectors and institutions.

The Lower Jurassic (Toarcian) Posidonienschiefer Formation of southwestern Germany is a classic konservat lagerstätte, yielding some of the world’s best-preserved fossils of marine vertebrates, including ichthyosaurs, thalattosuchian crocodylomorphs, plesiosaurs and fishes. Despite numerous studies concentrating on the taphonomy of ichthyosaurs in this formation, less taphonomic work has focussed on the thalattosuchians of the assemblage. Multiple thalattosuchian species displaying a wide range of body sizes have been recovered. We investigated indicators for seafloor arrival position in thirteen Macrospondylus bollensis and one Platysuchus multiscrobiculatus specimens representing various body sizes using three-dimensional (3D) photogrammetric models. False-colour depth maps were used to interpret the relative topography (depth level) of bone penetration into the sediment and were aligned on the XY plane, making them parallel to the stratigraphic plane. Our results show both headfirst and non-headfirst seafloor arrivals in observed specimens, with headfirst seafloor arrivals exhibiting deeply buried skulls, displacement of select cervical vertebrae and/or characteristic fractures in the cranium and mandible. We (1) interpret seafloor landing types in teleosauroids; (2) recognize and list specific characteristics that are consistently attributed to either a headfirst or non-headfirst seafloor arrival; (3) discuss possible factors that may have contributed to these features, such as body shape and size, substrate and velocity; and (4) provide a new definition for headfirst seafloor arrival that can be readily attributed to other marine vertebrates from various formations. Lastly, our results show that observers must carefully consider how historical specimens might have been prepared, as this may influence taphonomic interpretations.

This paper explores the implementation and enduring significance of the German language program in Milwaukee Public Schools between 1867 and 1918. Despite the German language program facing challenges, notably the Bennett Law of 1889—which sought to restrict foreign language instruction statewide—the program persisted, highlighting the tension between local identity and state mandates. This study argues that the creation of the German course initiated a process of consolidation and standardization in Milwaukee Public Schools, shifting decision-making to school administrators who sought to accommodate the largest cultural group in Milwaukee. This case study of the Milwaukee Public Schools’ German Language Program reveals how school policies prioritized a multilingual approach to Americanization. The paper is structured in three sections, examining the evolution of language policy, the political implications of the Bennett Law, and the post-Bennett landscape of language education, ultimately demonstrating the interplay between consolidation and cultural inclusivity.
