Conspicuous redemption? Reflections on the promises and perils of the 'celebritization' of climate change

With rising public awareness of climate change, celebrities have become an increasingly important community of non nation-state ‘actors’ influencing discourse and action, thereby comprising an emergent climate science–policy–celebrity complex. Some feel that these amplified and prominent voices contribute to greater public understanding of climate change science, as well as potentially catalyze climate policy cooperation. However, critics posit that increased involvement from the entertainment industry has not served to influence substantive long-term advancements in these arenas; rather, it has instead reduced the politics of climate change to the domain of fashion and fad, devoid of political and public saliency. Through tracking media coverage in Australia, Canada, the United States, and United Kingdom, we map out the terrain of a ‘Politicized Celebrity System’ in attempts to cut through dualistic characterizations of celebrity involvement in politics. We develop a classification system of the various types of climate change celebrity activities, and situate movements in contemporary consumer- and spectacle-driven carbon-based society. Through these analyses, we place dynamic and contested interactions in a spatially and temporally-sensitive ‘Cultural Circuits of Climate Change Celebrities’ model. In so doing, first we explore how these newly ‘authorized’ speakers and ‘experts’ might open up spaces in the public sphere and the science/policy nexus through ‘celebritization’ effects. Second, we examine how the celebrity as the ‘heroic individual’ seeking ‘conspicuous redemption’ may focus climate change actions through individualist frames. Overall, this paper explores potential promises, pitfalls and contradictions of this increasingly entrenched set of ‘agents’ in the cultural politics of climate change. Thus, as a form of climate change action, we consider whether it is more effective to ‘plant’ celebrities instead of trees.

The role of autophagy in anticancer therapy: promises and uncertainties

Autophagy (literally self-eating) is a catabolic mechanism involved in the recycling and turnover of cytoplasmic constituents. Although often referred to as type II programmed cell death, autophagy is primarily a survival rather than a cell death mechanism in response to different stress stimuli. Autophagy is a process in which part of the cytoplasm or entire organelles are sequestered into double-membrane vesicles, called autophagosomes, which ultimately fuse with lysosomes to degrade their contents. Studies show that autophagy is associated with a number of pathological conditions, including cancer, infectious diseases, myopathies and neurodegenerative disorders. With respect to cancer, it has been suggested that the early stages of tumourigenesis are associated with downregulation of autophagy-related (ATG) genes. Indeed, several ATG genes display tumour suppressor function, including Beclin1, which is frequently hemizygously deleted in breast cancer cells. Conversely, in advanced stages of tumourigenesis or during anticancer therapy, autophagy may promote survival of tumour cells in adverse environmental conditions. Therefore, a thorough understanding of autophagy in different cancer types and stages is a prerequisite to determine an autophagy-activating or autophagy-inhibiting treatment strategy.
