The full post by Christina Kefala can be read at https://blog.castac.org/2026/05/making-for-the-feed-creativity-platforms-and-visibility-in-china/. About the post: In China, creative production is immediately embedded within circuits of monetization and visibility. Content can move seamlessly from aesthetic expression to commercial transaction, collapsing distinctions between artist, influencer, and entrepreneur.

About the post: But, blood has never been a single, unified fluid. Among blood’s several components—red blood cells, plasma, platelets—not all have the same exact velocity. When I began developing my dissertation project, which seeks to ethnographically follow blood across myriad institutions, locales and historical periods, I started to observe different models that helped me visualize blood circulation. For me, the question is thus not only how does blood work, but also how is it seen? And how can we better see it?

The full post by Adam Matthew Mikhail can be read at https://blog.castac.org/2026/04/what-the-map-conceals-sovereignty-and-the-sea-in-the-strait-of-gibraltar/. About the post: Sovereignty at sea does not work the way maps suggest. The Strait of Gibraltar is not a line, it is a volume with depth, surface, and air. Its currents run in opposite directions, seasonal winds close it to small vessels for months, and fish migrations predate any legal framework by millennia. Governing this space means governing something that territorial thinking, built on the premise of fixed, bounded, and mappable surfaces, was never designed to handle.

About the post: People often ask me these questions when I present my research on my book, Data Borders: How Silicon Valley is Building an Industry Around Immigrants (2023 UC Press), which examines the growing industry of data collection for the surveillance and control of immigrants in the United States. These questions arise in undergraduate and graduate classrooms, at academic conferences, and among public workers in the United States. I respond by advocating for policy protections for immigrant information rights, providing examples of data rights activism, and demonstrating how we are applying techno-imagined futures within my Southern California community to advocate for humane shifts in technological design and data collection.

About the post: As Francis Nyamnjoh reminds us, both “[b]odies and forms are never complete; they are open-ended malleable vessels to be appropriated by consciousness in its multiplicity. Bodies provide for hearts and minds to intermingle, accommodating the dreams and hopes of both, and mitigating the propensity of the one to outrace the other” (Nyamnjoh, 2017, p. 257). This Platypus blog series explores how incompleteness provides an ethical stance by foregrounding interlinkages, connections and relations over the totalizing vision of African AI developments.

The full post by Misria Shaik Ali can be read at https://blog.castac.org/2026/03/on-resolving-controversies-enduring-regulatory-neglect-in-southern-tamil-nadu/. About the post: This post addresses how the controversy around the Kudankulam nuclear power Plant is being resolved, nearly 15 years after the 2011 protest where around 9000 people were charged with sedition and 55000 under several other charges. The post treats resolutions in three ways: resolving between multiple aspects and interest groups in a controversy, resolution as clarity about a controversy by meaning of accounting for the diverse perspectives, knowledges in decision making, and the resolved-ness against regulatory neglect. Resolving scientific controversies are significant to a dignified existence in the age of environmental in the age of environmental contamination, plagued by compounded causes and vulnerabilities. As science procedurally solves contamination’s cause, victims in contaminated places await technoscientific answers to establish regulatory accountability.

About the post: Despite the toxicity and the chromosome doubling and the botanical reality of peanut reproduction, Mars’s portrayal of peanut breeding as an all-natural gendered family unit contrasts the stability of the nuclear family with the instability of climate change. In doing so, the commodity, in this case Mars candies, becomes an essential safeguard against total climate and societal collapse–a world without peanuts.

The full post by Jonathan Givan can be read at https://blog.castac.org/2026/03/hip-hop-sampling-and-the-akai-mpc-as-a-platform-for-spatiotemporal-discourse/. About the post: This analysis moves away from exploring Hip Hop as a particular Black political action taking sonic form and towards an ontology of Black American Hip Hop production. This shift is valuable because the sonic underpinning of the beat is what contextualizes and informs the lyrical production done in real time by the emcee during the process of writing and recording their lyrics. In doing this contextualizing work, Hip Hop music producers redeployed the sampler as not just a musical instrument but as a platform on which new forms of dialogue were able to blossom.

This bonus content is a reading from Platypus, the CASTAC Blog. The full post by Rachel Lim can be read at https://blog.castac.org/2026/02/there-is-a-climate-emergency-and-its-called-colonialism/. About the post: In this piece, author and artivist Rachel Lim highlights how the climate crisis is not a sudden "emergency" but the cumulative result of centuries of colonial dispossession and extraction. Lim critiques "crisis language," noting it often sidelines Indigenous sovereignty and favors capitalist expansion over genuine accountability. By drawing on academic scholarship and solidarity work with land defenders from the Wet’suwet’en to the Amazon, Lim highlights how "green transitions" can replicate colonial violence if they ignore Indigenous jurisdiction. The piece serves as a call to move beyond fear-driven rhetoric toward a framework of reciprocity and history. Accompanied by Lim's illustration, "Rooted in Our Heart," the article demands that climate action addresses colonialism as its root cause to achieve true justice.

About the post: This post is an Interdisciplinary dialog on platforms and labor. We are a group of scholars and researchers who work with gig and platform worker unions in India in various capacities. We form the India chapter of the labor deck research network. We have been meeting regularly from across the globe to share cross-sectoral organizing strategies, track the political landscape around gig and platform movements, and discuss research and reflections from our place-based engagements. Our work sits at the critical intersection of scholarship and activism. It involves amplifying workers’ voices, supporting unionization efforts, and supporting workers in their struggles to lead more dignified and just working lives. Our discussions have inspired us to put together this blog series on the politics of writing about platform workers’ organizing.

About the post: Platform work has exposed larger numbers of workers, especially younger workers with little memory or experience of organising, to mobilise against capital and to do so using innovative means and campaigns. Through three vignettes, we bring the everyday together with the cultural, political histories and contexts of three metropolitan Indian cities – Bengaluru, Delhi and Kolkata, cities in which we have lived and engaged in research and activism with platform workers. Spanning between 2019 and 2025, these vignettes reflect the political landscape in India. They shed light on the capital–state nexus that limits the power of workers, unionization efforts built on foundations of loyalty and often exclusionary hypermasculine politics. What are the tensions and contradictions that we confronted while doing research with ‘gig’ worker unions? To inhabit that space in between is to acknowledge t

About the post: In this text, we intend to revisit the well-known case of the Portuguese sociologist Boaventura de Souza Santos, following its unfolding since the accusations that surfaced after the publication of this book "Sexual Misconduct in Academia" in 2023. We summarize the main events since then, focusing on developing a counter-manual that didactically organizes the regrettable way in which the intellectual responded to the accusations and systematically retaliated against the victims.

The full post by Renee Yu Jin can be read at https://blog.castac.org/2025/12/touch-to-make-an-index-fingers-path-into-the-sculpture-factories-in-china/. About the post: How do digital platforms reconfigure the ways we come to know sites of artistic labor before we ever enter the workshops? What began as a simple search for sculpture factories near Beijing became an encounter with how algorithmic recommendation, platform aesthetics, and factory self-promotion organize visibility for contemporary sculpture production. As clips foreground technological capability and optimized workflows while workers remain partially obscured, a layered form of mediation emerges, one that frames the factory as a digital formation long before it becomes a physical place. Tracing how my own scrolling shaped this encounter, this piece examines how touch, vision, and labor move across screens and shop floors, revealing how digital circulation both illuminates and abstracts the embodied work of sculpture making in China.
