Fast and Slow Signal Propagation in Abiotic Polypeptide Assemblies

ChemBioChem, Volume 27, Issue 6, 27 March 2026.
Proteinoid microspheres formed by thermal polymerization of amino acids exhibit spontaneous electrical potential fluctuations without genetic material, membranes, or ion channels. Multi‐electrode recordings and electron microscopy reveal composition‐dependent voltage oscillations, long‐term drifts, and correlated signals across electrodes.

Critical Discursive Psychology and the Society of the Spectacle: A Debordian Approach to Digital Technologies

Journal of Community &Applied Social Psychology, Volume 36, Issue 2, March/April 2026.
ABSTRACT This paper proposes a critical framework that merges Critical Discursive Psychology (CDP) with Guy Debord's Society of the Spectacle to explicate the discourses surrounding digital technologies. Although CDP offers an analytic lens for examining how language constructs subjectivities, identities and ideological frameworks, it has yet to fully ...
