Electroconductive Soft Microcarriers for Suspension Culture of Skeletal Muscle Cells

Macromolecular Bioscience, Volume 26, Issue 6, June 2026.
ABSTRACT The advancement of conductive biomaterials is essential for engineering electrically responsive tissues, such as skeletal muscle, cardiac, and neural tissues. Traditional hydrogel‐based microcarriers (MCs) lack inherent conductivity, limiting their potential for cell signaling and differentiation. In this study, we present a soft conductive MC

Asylum as Artifice: Race, Law and Capital as Regimes of Abstraction in the United Kingdom's Asylum Accommodation System

Transactions of the Institute of British Geographers, Volume 51, Issue 2, June 2026.
ABSTRACT Taking as its case study the category of the ‘asylum seeker’ in UK law, this paper develops on latent concerns in legal geographies with processes of abstraction. Following Bhandar and Toscano, race, law and capital are here understood as different, co‐articulating modalities of abstraction, through which the ‘asylum seeker’ is constituted and
