About the post: The above scene from Ramy (Season 2, Episode 7) depicts an absurd yet moving moment featuring characters Mo and Ahmed performing umrah through VR headsets. As Mo embraces the virtual Ka’aba, he tearfully breaks down; we see a performance of embodied devotion through his digitally mediated umrah experience. While VR pilgrimages remain niche and laughable to many, their use by some travel agencies and religious groups to practice for actual pilgrimage highlights how digital technologies are reshaping sacred journeys. This project attempts to interrogate how digital mediation transforms spatiotemporal logics of religious practice particularly through the lens of chronotope (Bakhtin 1981, Agha 2007), the co-constituion of time and space in narrative and interaction. Linguistic anthropology’s concept of chronotope may help us unpack this tension.

About the post: Delivery workers do not merely use communication platforms; they inhabit and transform them into sociotechnical infrastructures of collective life. Through these arrangements, knowledge, social relations, moral authority, and identity are actively produced and maintained. In tracing the circulation of information, responsibility, and care across urban and transnational space, this blogpost reveals how systems designed for labor extraction are repurposed as infrastructures of care, accountability, and collective knowledge across neighbourhoods and national borders.

The full post by Aldo Federico Palafox Hernández can be read at https://blog.castac.org/2026/09/kilitl-living-with-a-green-part-of-the-world-edible-greens-language-knowledge-and-territory/. About the post: In Mexico, quelites refers to uncultivated edible plants. The word has a Nahuatl origin derived from kilitl, a term referring to these edible weeds. The earliest dictionaries of colonial Mexico translated kilitl as “vegetable”, an equivalence that obscured the fact that they were collected (not cultivated), and interpreted them as any other green crop. There is an ongoing trend to revaluate quelites as a way to counter their gradual disappearance from national diets. These efforts involve universities, governmental and private institutions, civil associations, and organized communities.

About the post: Global South, global majority, and decolonial lenses help us to break out of dominant points of view. Taking on a range of methods, the empirical and conceptual works draw lessons from workers’ embodied experiences and relationships to one another and to the places they work, from discourse and discursive objects, and from speculative engagements.

About the post: Anthropologists have long framed studying up as a problem of access: how to get inside institutions that do not want us (Nader 1972; Souleles 2018). My problem was different. Having spent time doing both ethnographic fieldwork and leading several venture investments, my problem was less about access than about processing the continuities and frictions between these two roles.

About the post: In 1870, the Vedaranyam canal is built connecting the Salt Pans nearby Palk bay coasts 5 to Nagapattinam – serving twin purposes of cheap transport of salt to Nagapattinam for trade, as well as deepening the river channels slightly upstream of the Port. A permanent wharf was constructed from some of the dredged sand in the 1870s. But dredging was repeatedly claimed as costly. Equally, the cyclone of 1862 damaged the extended river mouth groynes, and the British were able to repair them only by 1865. In 1909, experimental groynes erected at a distance from the river mouth were destroyed and washed away further south during the North East monsoon – which the Port Officer describes as “It will be seen by the above that these exposed groynes cannot withstand the fury of the northeast monsoon, and any expenditure on this account will be a waste of money”.

About the post: An essay on incompleteness as a constitutive property of biometric infrastructures. Beginning with the removal of two wisdom teeth — a piece of the body that leaves it once but whose record may keep circulating — it traces how bodies are decomposed into data, archived, and returned to their subjects only in fragments that never quite align. At its center is a speculative biometric archive, built as an interactive component, that enacts this logic directly: records repeat, some accesses are denied, and discovered records decay permanently with use. A horse the system cannot classify — but files anyway — marks the limit of what such an archive can hold. (This episode is available in additional languages on Platypus, The CASTAC Blog.)

About the post: Chinese romance games are built to make players feel heard, and the studios behind them promise the same. Drawing on fieldwork among players of China's female-oriented mobile games, this piece follows listening as it slips from a designed intimacy into a demand players make on the companies, and on the worlds these games represent.

About the post: My students were actively evaluating AI's role and utility rather than absorbing it uncritically. This complicates the assumption that children are passive recipients of a technological future being built for them. Education policy is actively being shaped by the potential of an education in and conducted by AI rather than considering the students they are pushing this upon
