The growth of responsible innovation scholarship has been mirrored by a proliferation of RI definitions and practices, as well as a recognition of the importance of context for RI. This study investigates how researchers in the field of nanotechnology for food and agriculture define and practice RI, as well as what motivations they see for pursuing RI. We conducted 20 semi-structured interviews with nano-agrifood researchers from industry and academia in the USA, where we asked them to describe their RI definitions, (...) practices, and motivations. We analyzed the emergent themes from these interviews, including how the themes aligned with four prominent RI principles. We found that nano-agrifood researchers largely focused their descriptions of RI definitions, practices, and motivations around a narrow envisioning of the RI principle of anticipation — emphasizing product safety, efficacy, and efficiency. We also found noteworthy tensions surrounding the less frequently mentioned RI principles. For example, some researchers envisioned inclusion as a way to align products with industry interests while others saw it as a way to align products with the public good. Concerning motivations for RI, some researchers viewed RI as a way to protect one’s reputation and avoid lawsuits while others viewed it as a way to improve human well-being and solve societal problems. Given these findings, future efforts to foster RI within nano-agrifoods should promote discussions among researchers concerning what it means to responsibly innovate and what practices this could entail, particularly beyond ensuring product safety, efficacy, and efficiency.

Cell membranes experience frequent stretching and poking: from cytoskeletal elements, from osmotic imbalances, from fusion and budding of vesicles, and from forces from the outside. Are the ensuing changes in membrane tension localized near the site of perturbation, or do these changes propagate rapidly through the membrane to distant parts of the cell, perhaps as a mechanical mechanism of long‐range signaling? Literature statements on the timescale for membrane tension to equilibrate across a cell vary by a factor of ≈106. This (...) study reviews and discusses how apparently contradictory findings on tension propagation in cells can be evaluated in the context of 2D hydrodynamics and poroelasticity. Localization of tension in the cell membrane is likely critical in governing how membrane forces gate ion channels, set the subcellular distribution of vesicle fusion, and regulate the dynamics of cytoskeletal growth. Furthermore, in this study, it is proposed that cells can actively regulate the degree to which membrane tension propagates by modulating the density and arrangement of immobile transmembrane proteins.

This paper explores the events surrounding a string of robberies from the homes of young celebrities living in Los Angeles County by a group of teenagers referred to by the media as “The Bling Ring.” It argues that the group demonstrates the intersections of desire and materiality under the conditions of a culture driven by idolization of the celebrity, referring to the works of Jean Baudrillard, Pierre Bourdieu, and French collective Tiqqun. It further examines the events as a moment where (...) subjects were able to escape the life-narratives imposed upon them by the State. Rather than adhering to the norms of regular adolescent life, reproduced and enforced through what Michael Shapiro identifies as “national-time,” members of the Bling Ring endeavored to create their own lives according to what I refer to as “celebrity-time,” revealing processes of becoming in the work of Gilles Deleuze, and plasticity in that of Catherine Malabou.

While agreeing with Poteat that the modern Western culture has gone awry in a humanly destructive way, the paper contends tha the culprit was not, as Poteat claims, Enlightenment critical philosophy, but the materialistic values of the bourgeois form of life and the puritanical view of knowledge and the naturalistic worldview that they generated. Accordingly, the solution proposed is not Poteat's unreflected experience and commonsense worldview but a shift to a humanistic culture-generating stance and a critical humanistic philosophy.
