| Summary/Abstract |
Thanks to scientific discoveries and commercial efforts to harness the processes of fermentation going back to the nineteenth century, enzymes harvested from microbes have become ubiquitous in detergents and other cleaning products, as well as in food production. They are also now being adapted for an even bigger cleaning task: remediating pollution. Examining how these humble proteins and the biochemical reactions they catalyze became so indispensable reveals a little-noticed history of industrialization underlying modern everyday life.

| Summary/Abstract |
With the advent of smartphones and social media, non-elites possess more resources to engage in politicisation and securitisation of issues. The increasing popularity and acceptance of eyewitness videos captured by non-elites presents new political-security implications, especially for the issue of migration and refugees, as witnessed during the European refugee crisis. The eyewitness videos the host population of Europe captured served as key heuristic artefacts for non-elites to engage in the securitisation and counter desecuritisation of asylum seekers. The production, visual, circulation, and audiencing aspects of eyewitness videos are significantly different from those of professional videos from news media and therefore can potentially articulate (in)security in distinct ways. I argue that the epistemic-political constitution of eyewitness videos and their online remediation through the complex networked act between the calculated security publics and video recommendation algorithms of social media play a key role in facilitating security articulations of asylum seekers. This is illustrated in the analysis of two popular eyewitness videos from Calais. The article examines how non-elites used eyewitness videos to politicise and securitise Calais asylum seekers.

| Summary/Abstract |
Digital videos increasingly sustain new and older imagined communities (and enmities), and make battlefields, unfolding terror plots and emergencies public. Yet digital videos mediate security articulations following logics that are radically different from those of journalistically edited media, with consequences for how we should think of security articulation in new visual media. This article analyses how, in digital video, the combination of visible facts and the remediation logics of algorithmically governed video platforms – such as YouTube and Facebook – allow for new types of security articulations. It argues that digital video can be understood as a semiotic composite where the material semiotics of media technologies, calculated publics and spectators combines with the political semiotics of audio-visual media to condition how video articulations work as political agency. A powerful video-mediated security articulation, the #neda videos from the 2009 Iranian post-election crisis, illustrates how security articulation in digital video is not tied to the authority of a speaker and does not contain the promise of an immediate, illocutionary security effect. Drawing on securitization theory and Butler’s critique of speech act theory, this article understands such video articulations as post-sovereign security articulations.
