About the post: Wildfire smoke toxicity is linked with multisystemic adverse health effects. Scientists are increasingly studying wildfire health impacts beyond respiratory and cardiovascular effects, including fertility issues and dementia. But what if we’ve been getting wildfire smoke wrong when we interpret it exclusively as a matter of exposure and a public health concern?

About the post: Experimental "ecosystems" emerge from the relation between facilities. The DSE case shows how ecosystems are defined relationally, not only through interoperability (as with LEO), but also through ever-analogical definitions: the "ecosystem" idea is located at the meeting point of fully-interdependent instantiations by various experimental facilities across continents.

About the post: Should we refrain from kicking science when it is down? Ought the level of our critique be calibrated by how vulnerable the scientific enterprise is in a given moment? Would we dare release a book called Against Health (Metzl & Kirkland 2010) in 2025, when being against health seems to explicitly be the order of the day? And how do we speak honestly about how much worse things have gotten without rehabilitating the tepid liberalism which got us here in the first place?

About the post: At Alliance Wellness, I also noticed how young Somali American men turn to humor and laughter to socialize experiences of sobriety or resist the structure and authority of Alcoholics Anonymous discourse while establishing rebellious rhythms and narratives of sobriety. However, as I played Ludo with these young men, I became more interested in how laughter also served as a ventilator of life and a space to imagine victory. The moment Somali American men entered their sober-living facilities, I would hear deep sighs of exhaustion and relief. Evenings at these sober homes became a site of raaxo (Somali for ease or pleasure) or nasasho (Somali for rest), phrases these young Somali American men informed me were among the many Somali words for healing.

The full post by Ana Carolina de Assis Nunes and Felipe Figueiredo can be read at https://blog.castac.org/2025/04/data-centers-transnational-collaborations-and-the-differing-meanings-of-connection/. About the post: As anthropologists researching data centers, one of our goals is to point to a deeper timeline of events that have given form to what data centers are today. Our goal is to put data centers in context, and to reject narratives that place them outside of history. In putting data centers in context, we understand that the technology and infrastructure supporting current data centers are not new or exist thanks to the works of a single mind – putting data centers in context shows how digital technologies of the 21st are enacting forbindelse, they’re combining pre-existing infrastructures and creating new relationships with other material technologies. They’re connected to the past, despite the focus of the tech industry in a distant future, and their rejection of history.

The full post by Jiwon Kim can be read at https://blog.castac.org/2025/04/from-bin-to-bank-recycling-household-waste-in-urban-indonesia/. About the post: Environmental activists and industry professionals were hesitant to view them more than “housewives’ plaything (main-mainan).” The quantity of waste banks’ contribution to handling household waste pale in comparison to that of the informal waste pickers. Meanwhile, the members of waste banks themselves often describe their activity as “just social (sosial),” implying its communal nature is predicated on the absence of economic aspirations. This essay is an attempt to create a generative interval between them—one that pauses before settling into any singular narrative, allowing the complexity of waste bank practices to surface.

About the post: While potato farmers have been referred to as “guardians” of agrobiodiversity, little attention has been brought to the precarity of the continuity of this guardianship. The lack of youth and women farmers present at annual meetings and events puts into question who will be the agrodiversity guardians when the older generations of potato farmers pass on.

About the post: In a looping story of strata and sediment and edible rocks, this essay similarly seeks to articulate the material instabilities of bodies in an epoch that itself resists clear definition. Through the generative space of contradictions, it serves as a somewhat experimental back-and-forth between permeable anthropos bodies and the epoch defined by the materials transgressing those bodies; between tangible forms of evidence and ephemeral ones; between precision and porosity.

About the post: This blog series emerges from porous interventions at the intersections of environmental humanities and science and technology studies whereby scientized objects are opened to the world they animate through ethnographic engagements.
