What should we know of cricket who only England know? : cricket and its heroes in English and Caribbean literature

As the game of England and empire, cricket is a significant colonial and postcolonial cultural practice which has proven as important to anti colonial modes of resistance, opposition and independence as its image of Englishness was to the hegemonizing project of British imperialism. Although the game has an immense literature of its own, little critical attention has been paid to its place in the field of literary studies. Consequently, taking its title and starting point from the interwoven questioning of Rudyard Kipling and C. L. R. James, this thesis explores cricket's repeated presence in English and Caribbean literature as a symbol of interconnected national and imperial identities under constant renegotiation, concentrating specifically on the construction and problematization of the male cricket hero - real and/or fictional - from Tom Brown to Brian Lara. Organized around the territorial metaphor of the crease, Part One, `English Literature at the Imperial Crease 1850s-1950s', offers two chapters which examine the place of cricket in the creation, imperial contextualization and post war decline of the English cricketing gentleman as a hero of the nation. Part Two, `Caribbean Heroes at the Literary Crease after 1950', engages with cricket's relation to the masculine quest for independence in Trinidadian literature as well as a range of poetic representations of the Caribbean's substantial investment in cricket heroes. Finally, Part Three, `The Straight White Line', re-evokes the crease as line and territory to read the trans-gendered British Caribbean cricketing body of Neil Jordan's The Crying Game (1992). The thesis argues that while cricket has been a valuable vehicle for the postcolonial expression of freedom in the Caribbean and elsewhere it has also remained tied to an over investment in individual male heroes which continues to pose substantial problems to projects of collective emancipation

Cricket and the World-System, or Continuity, “Riskless Risk” and Cyclicality in Joseph O’Neill’s Netherland

In Joseph O’Neill’s Netherland (2008), cricket is the dominant thematic mechanism, and anchoring allegorical device, through which the novel encodes the capitalist world-system, including the ways in which structural continuity and “riskless risk” are glorified as the neo-liberal conditions for a cosmopolitan class of white international workers, in the face of, and directly at the expense of, their racialized, economic and cricketing “Other”. This encoding renders visible the “systemic cycles of accumulation” that characterize the history of capitalism. Yet the novel goes to extreme lengths to hold off, seemingly as perpetual delay, the failure-filled future consequences of its own leaked revelations. Hence, it is only by resituating Netherland in a world-systemic frame that critical sense can be made of Hans’s feigned cricketing bildung and the novel’s Dutch-English-American journey of cyclical continuity

Metamorphic evolution of carbonate-hosted microbial biosignatures

This work was funded by a Royal Society of Edinburgh Research Fellowship. FF and FW acknowledge funding from the CNRS and CNES.Microbial biosignature assemblages captured within mineral substrates experience extreme pressures (P) and temperatures (T) during rock burial and metamorphism. We subjected natural microbial biofilms hosted within thermal spring carbonate to six high pressure, high temperature (HPHT) conditions spanning 500 and 800 MPa and 200 to 550 °C, to investigate the initial petrographic transformation of organic and inorganic phases. We find biogenic and amorphous silica mineralises increasingly mature organic matter (OM) as temperature and pressure increase, with OM expelled from recrystallised calcite at the highest HPHT, captured within a quartz phase. Sulfur globules associated with microbial filaments persist across all HPHT conditions in association with microbially-derived kerogen. These data demonstrate how microbial material captured within chemically-precipitated sediments petrographically evolves in high grade rocks during their first stages of transformation.Publisher PDFPeer reviewe

Darwin -— an experimental astronomy mission to search for extrasolar planets

As a response to ESA call for mission concepts for its Cosmic Vision 2015–2025 plan, we propose a mission called Darwin. Its primary goal is the study of terrestrial extrasolar planets and the search for life on them. In this paper, we describe different characteristics of the instrument

Geyserite in Hot-Spring Siliceous Sinter: Window on Earth’s Hottest Terrestrial (Paleo)environment and its Extreme Life

International audienceSiliceous hot-spring deposits, or sinters, typically form in active, terrestrial (on land), volcanic terrains where magmatically heated waters circulating through the shallow crust emerge at the Earth's surface as silica-charged geothermal fluids. Geyserites are sinters affiliated with the highest temperature (~ 75–100 °C), natural geothermal fluid emissions, comprising localized, lithologically distinctive, hydrothermal silica precipitates that develop around geysers, spouters and spring-vents. They demarcate the position of hot-fluid upflow zones useful for geothermal energy and epithermal mineral prospecting. Near-vent areas also are “extreme environment” settings for the growth of microbial biofilms at near-boiling temperatures. Microbial biosignatures (e.g., characteristic silicified microbial textures, carbon isotopes, genetic material, lipid biomarkers) may be extracted from modern geyserite. However, because of strong taphonomic filtering and subsequent diagenesis, fossils in geyserite are very rare in the pre-Quaternary sinter record which, in and of itself, is patchy in time and space back to about 400 Ma. Only a few old examples are known, such as geyserite reported from the Devonian Drummond Basin (Australia), Devonian Rhynie cherts (Scotland), and a new example described herein from the spectacularly well-preserved, Late Jurassic (150 Ma), Yellowstone-style geothermal landscapes of Patagonia, Argentina. There, geyserite is associated with fossil vent-mounds and silicified hydrothermal breccias of the Claudia sinter, which is geologically related to the world-class Cerro Vanguardia gold/silver deposit of the Deseado Massif, a part of the Chon Aike siliceous large igneous province. Tubular, filament-like micro-inclusions from Claudia were studied using integrated petrographic and laser micro-Raman analysis, the results of which suggest a biological origin. The putative fossils are enclosed within nodular geyserite, a texture typical of subaerial near-vent conditions. Overall, this worldwide review of geyserite confirms its significance as a mineralizing geological archive reflecting the nature of Earth's highest temperature, habitable terrestrial sedimentary environment. Hot-spring depositional settings also may serve as analogs for early Earth paleoenvironments because of their elevated temperature of formation, rapid mineralization by silica, and morphologically comparable carbonaceous material sourced from prokaryotes adapted to life at high temperatures

CD8+ T cells specific for an immunodominant SARS-CoV-2 nucleocapsid epitope display high naive precursor frequency and TCR promiscuity

To better understand primary and recall T cell responses during coronavirus disease 2019 (COVID-19), it is important to examine unmanipulated severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-specific T cells. By using peptide-human leukocyte antigen (HLA) tetramers for direct ex vivo analysis, we characterized CD8+ T cells specific for SARS-CoV-2 epitopes in COVID-19 patients and unexposed individuals. Unlike CD8+ T cells directed toward subdominant epitopes (B7/N257, A2/S269, and A24/S1,208) CD8+ T cells specific for the immunodominant B7/N105 epitope were detected at high frequencies in pre-pandemic samples and at increased frequencies during acute COVID-19 and convalescence. SARS-CoV-2-specific CD8+ T cells in pre-pandemic samples from children, adults, and elderly individuals predominantly displayed a naive phenotype, indicating a lack of previous cross-reactive exposures. T cell receptor (TCR) analyses revealed diverse TCRαβ repertoires and promiscuous αβ-TCR pairing within B7/N105+CD8+ T cells. Our study demonstrates high naive precursor frequency and TCRαβ diversity within immunodominant B7/N105-specific CD8+ T cells and provides insight into SARS-CoV-2-specific T cell origins and subsequent responses
