Dirty footprints and degenerate archives: Tabitha Nikolai’s impure walking sims
Tabitha Nikolai’s Shrine Maidens of the Unseelie Court and Ineffable Glossolalia are impure specimens of the walking sim. While these are still first-person games that see players exploring eerily underpopulated environments and archiving textual fragments, they are at once more aesthetically reflexive and more refer-entially dense than many walking sims. Accommodating giant spiders, Weimar sexologists, messageboard trolls and quotations from Roman poetry, Nikolai’s unorthodox spins on the ‘archival adventure’ reflect her interest in queer and trans history and her commitment to interrogating discourses of purity, progress and redemption. Reviewing critical discussions of the walking sim alongside queer, trans and decolonial perspectives on archives, identity and subjectification, the article argues that while walking sims have often been praised for telling emotion-ally engaging stories, in Nikolai’s hands the form assumes different function: that of reckoning with history and exploring subjectivity

CUL-2<sup>LRR-1</sup> and UBXN-3 drive replisome disassembly during DNA replication termination and mitosis
Replisome disassembly is the final step of DNA replication in eukaryotes, involving the ubiquitylation and CDC48-dependent dissolution of the CMG helicase (CDC45-MCM-GINS). Using Caenorhabditis elegans early embryos and Xenopus laevis egg extracts, we show that the E3 ligase CUL-2(LRR-1) associates with the replisome and drives ubiquitylation and disassembly of CMG, together with the CDC-48 cofactors UFD-1 and NPL-4. Removal of CMG from chromatin in frog egg extracts requires CUL2 neddylation, and our data identify chromatin recruitment of CUL2(LRR1) as a key regulated step during DNA replication termination. Interestingly, however, CMG persists on chromatin until prophase in worms that lack CUL-2(LRR-1), but is then removed by a mitotic pathway that requires the CDC-48 cofactor UBXN-3, orthologous to the human tumour suppressor FAF1. Partial inactivation of lrr-1 and ubxn-3 leads to synthetic lethality, suggesting future approaches by which a deeper understanding of CMG disassembly in metazoa could be exploited therapeutically
Thinking and Doing: Challenge, Agency, and the Eudaimonic Experience in Video Games
The nascent growth of videogames has led to great leaps in technical understanding in how to create a functional and entertaining play experience. However, the complex, mixed-affect, eudaimonic entertainment experience that is possible when playing a video game—how it is formed, how it is experienced and how to design for it, has been investigated far less than hedonistic emotional experiences focusing on fun, challenge and ‘enjoyment.’ Participants volunteered to be interviewed about their mixed-affect emotional experiences of playing avant-garde videogames. New conceptions of agency emerged (Actual, Interpretive, Fictional, Mechanical) from the analysis of transcripts and were used to produce a framework of four categories of agency. This new framework offers designers and researchers the extra nuance in conversations around agency, and contributes to the discussion of how we can design video games that allow for complex, reflective, eudaimonic emotional experiences

Identifying type 316 SS portable x-ray fluorescence gauge. [For certification of stainless Type 316 in gloveboxes]
The system as assembled by LASL Group M-1 performs a quick go-no-go test to separate Type 316 stainless from other types of stainless steel. The x-ray from /sup 109/Cd excites an absorption edge x-ray from the element molybdenum which is present in Type 316 at 2 percent concentrations. The source holder and collimator, designed and fabricated by Group M-1 are the unique parts in the system. The other parts, source, detector and electronics are commercial products
