The Violent Narrowing of Animal Life
Mainstream environmentalism has long prioritized wild animals and their habitats while paying little attention to the explosive growth of global livestock production and consumption. However, this blind spot to livestock is changing quickly, in large part because of the rising general awareness of the resource and emissions intensity of animal-based foods and how it relates the interwoven crises of climate change and biodiversity loss. This paper considers both the fertile ground for animal advocacy to be found in the mounting scientific evidence about environmental inefficiencies of animal-based foods, and the need to be attentive to the risks it bears. The principal danger of efficiency-centred narratives is that if they are largely focused on climate change and biodiversity loss, the goal of reducing relative associated impacts can appear in a way that helps to further stoke the growth of industrially produced birds, which should be understood in relation to the already well-established poultrification of global livestock supply and demand. This paper highlights the importance of challenging this partial lens and response, and stresses the need to connect macro-scale environmental concerns to critical reflection about the ways that animal lives are organized in industrial livestock production. The concern for declining wild animal populations among environmentalists is a key lever for this, as industrial livestock can be shown to bear on the loss and fragmentation of habitats while at the same condemning a large and growing share of all birds and mammals to a short and agonizing existence. What emerges is an indelible image of a pathological mode of production that is violently narrowing how other animals get to inhabit the earth
The meatification and re-meatification of diets: The unequal burdens of animal flesh and the urgency of plant-meat alternatives
* This report reviews the trajectories of meat consumption shifting from the periphery to the center of human diets (i.e. "meatification") in six countries (two high-income - U.S., Germany; two upper middle-income - Brazil, China; two lower middle-income - India, Nigeria). It also suggests that plant-based ingredients that resemble meat (i.e. "plant-meats") could play an crucial role in reversing meatification although they should not be seen as a silver bullet.* These six countries are chosen as case studies to illuminate the highly uneven character of global livestock production and meat consumption. This unevenness indicates the need to prioritize certain countries in efforts to address the negative impacts of meatification.* The report also draws attention to some critically important points to bear in mind when trying to address meat consumption and production concerns: 1) A handful of huge transnational corporations dominate livestock slaughter and processing, and exert significant influence over meat production and consumption on a world scale. 2) The rise in global meat consumption is not only influenced by consumer preferences and demand, but also affected by agrarian changes and powerful actors in the agro-food system seeking to expand livestock production and absorb chronic grain and oilseed surpluses. 3) Meatification has triggered serious environmental problems

Introduction: critical perspectives on food sovereignty
Visions of food sovereignty have been extremely important in helping to galvanize broad-based and diverse movements around the need for radical changes in agro-food systems. Yet while food sovereignty has thrived as a ‘dynamic process’, until recently there has been insufficient attention to many thorny questions, such as its origins, its connection to other food justice movements, its relation to rights discourses, the roles of markets and states and the challenges of implementation. This essay contributes to food sovereignty praxis by pushing the process of critical self- reflection forward and considering its relation to critical agrarian studies – and vice versa
An in-flight plasma diagnostic package for spacecraft with electric propulsion
The plasma diagnostics presented in this article target the plasma surrounding a spacecraft that is created by the electric thruster and its surface modifying effects. The diagnostic package includes a retarding potential analyzer, a plane Langmuir probe, and an erosion sensor. The paper describes the instrument as well as suitable test environments for mimicking the effects expected in space and shows test results. The system is to fly for the first time on the Heinrich Hertz satellite, which is scheduled to be launched in 2023. The spacecraft will be equipped with a pair of Highly Efficient Multistage Plasma Thrusters (HEMPT) and a pair of Hall thrusters for redundancy
Candida albicans β-Glucan Differentiates Human Monocytes Into a Specific Subset of Macrophages
β-Glucan derived from cell walls of Candida albicans is a potent immune modulator. It has been shown to induce trained immunity in monocytes via epigenetic and metabolic reprogramming and to protect from lethal sepsis if applied prior to infection. Since β-glucan-trained monocytes have not been classified within the system of mononuclear phagocytes we analyzed these cells metabolically, phenotypically and functionally with a focus on monocyte-to-macrophage differentiation and compared them with naïve monocytes and other types of monocyte-derived cells such as classically (M1) or alternatively (M2) activated macrophages and monocyte-derived dendritic cells (moDCs). We show that β-glucan inhibits spontaneous apoptosis of monocytes independent from autocrine or paracrine M-CSF release and stimulates monocyte differentiation into macrophages. β-Glucan-differentiated macrophages exhibit increased cell size and granularity and enhanced metabolic activity when compared to naïve monocytes. Although β-glucan-primed cells expressed markers of alternative activation and secreted higher levels of IL-10 after lipopolysaccharide (LPS), their capability to release pro-inflammatory cytokines and to kill bacteria was unaffected. Our data demonstrate that β-glucan priming induces a population of immune competent long-lived monocyte-derived macrophages that may be involved in immunoregulatory processes

Food Consumption and its Impact on Cardiovascular Disease: Importance of Solutions Focused on the Globalized Food System A Report From the Workshop Convened by the World Heart Federation
Major scholars in the field, based on a 3-day consensus, created an in-depth review of current knowledge on the role of diet in CVD, the changing global food system and global dietary patterns, and potential policy solutions. Evidence from different countries, age/race/ethnicity/socioeconomic groups suggest the health effects studies of foods, macronutrients, and dietary patterns on CVD appear to be far more consistent though regional knowledge gaps are highlighted. There are large gaps in knowledge about the association of macronutrients to CVD in low- and middle-income countries (LMIC), particularly linked with dietary patterns are reviewed. Our understanding of foods and macronutrients in relationship to CVD is broadly clear; however major gaps exist both in dietary pattern research and ways to change diets and food systems. Based on the current evidence, the traditional Mediterranean-type diet, including plant foods/emphasizing plant protein sources, provides a well-tested healthy dietary pattern to reduce CV
The Rise, Fall and Future of the Jamaican Peasantry
This article examines the crisis of the Jamaican peasantry. Jamaica\u27s peasants are struggling against pressures old and new, with the burden of their spatial inheritance magnified by a withering state, rising food imports following trade liberalisation, and oft-conflictive social relations. It begins by examining the historical formation of the peasantry after Emancipation, emphasising the unevenness of the landscape and the tensions between individualism and cooperation, before describing the protracted process of de-peasantisation, which has sped under structural adjustment reforms. Current conditions and future prospects are assessed through the insights and experiences of peasant farmers situated on the periphery of a plantation landscape. Ultimately, the future of peasant farming in Jamaica is seen to be bound up foremost in the struggle for land reform, and it is hoped that the current de-stabilisation of the plantation system will provide a new window for historic change
