Este ensayo tiene por objetivo analizar el poemario Martes Verde (2018), surgido de recitados colectivos en torno a la lucha por el aborto legal en Argentina, en términos de poesía de acción. En particular, el trabajo indaga en los modos en que el campo sonoro y vibratorio en los poemas funciona como una materialidad que genera una estética participativa, que a través de una imaginería y rítmica que evoca, olas, círculos, aleteos, apela a formas de colectividad.

Renewable energy is recognized as a cornerstone in achieving sustainable development globally, evidenced by international standards such as the UN Agenda 2030 as well as in nations energy policies globally. One of the front runners of the energy transition globally is Brazil, where wind energy has expanded substantially since the early 2000's. Currently, the state of Bahia in North-Eastern Brazil is seeing the fastest expansions, a state that is characterised by its many traditional and Indigenous communities. Although wind energy is known for its positive sustainability aspects, conflicting wind energy narratives and politics are abundant in this region. The fast expansion of wind energy projects has caused socio-environmental conflicts due to land related conflicts and expulsion of traditional communities for the creation of wind energy parks. In this study, we apply document analysis to critically explore the multiple narratives surrounding wind energy expansion in the state of Bahia. This study shows that different actors frame the matter differently, showcasing that civil society and local perspectives are made invisible in policy documents and decision-making processes. Our results suggest that the dominant narrative of wind power as the most sustainable energy option excludes the contrasting perspectives, perpetuating exclusion and marginalisation of local communities as well as the environment that are directly impacted by the expansion of wind energy projects.

RESUMEN Este artículo analiza las narrativas e imaginarios geográficos del Antropoceno en torno a dos hitos hidroeléctricos en la Patagonia argentina: la construcción del complejo Chocón-Cerros Colorados (1968-1977) y las represas Cóndor Cliff-La Barrancosa (desde 2013). A partir de perspectivas de la Ecología Política y los Ecofeminismos Latinoamericanos, problematizamos los entrelazamientos energéticos entre trabajo, naturaleza y desarrollo en la Patagonia centrándonos en la hidroenergía. El análisis realizado, a partir de cortometrajes estatales, empresariales y sindicales y producciones artísticas y artivistas, permite identificar las condiciones situadas que caracterizan el Antropoceno en la Patagonia, marcado por el origen y persistencia del imaginario "Patagonia-energía" y su signo civilizatorio-desarrollista. Finalmente, ponemos de relieve un frente de resistencia en la región que se despliega desde la lucha obrera del Choconazo en 1969 a la resistencia indígena y los frentes ecofeministas actuales contra el Terricidio.

The national implementation of electricity generation projects directly threatens the livelihoods of local and Indigenous communities in Latin America. Therefore, it is crucial to search for solutions to energy supply considering local needs and cosmologies. This article focuses on micro-energy production in rural settlements on the Colombian Caribbean coast. The aim is to provide insights into the relationship between energy, technology, and ancestrality through the lens of solarpunk storytelling. To explore this theme, we present the «tech to embrace the sun» initiative as a case study to co-design and imagine desirable futures by the local community of Selvatorium, in La Guajira. The results consist of the development of seven future ancestral stories co-written by community members and guests, two guides to build two prototypes, and a fanzine. The project concludes with empirical and theoretical insights for development studies about sustainable energy futures.

High-fat (HF) and rapid digestive (RD) carbohydrate diets during pregnancy promote excessive adipogenesis in o spring. This e ect can be corrected by diets with similar glycemic loads, but low rates of carbohydrate digestion. However, the e ects of these diets on metabolic programming in the livers of o spring, and the liver metabolism contributions to adipogenesis, remain to be addressed. In this study, pregnant insulin-resistant rats were fed high-fat diets with similar glycemic loads but di erent rates of carbohydrate digestion, High Fat-Rapid Digestive (HF–RD) diet or High Fat-Slow Digestive (HF–SD) diet. O spring were fed a standard diet for 10 weeks, and the impact of these diets on the metabolic and signaling pathways involved in liver fat synthesis and storage of o spring were analyzed, including liver lipidomics, glycogen and carbohydrate and lipid metabolism key enzymes and signaling pathways. Livers from animals whose mothers were fed an HF–RD diet showed higher saturated triacylglycerol deposits with lower carbon numbers and double bond contents compared with the HF–SD group. Moreover, the HF–RD group exhibited enhanced glucose transporter 2, pyruvate kinase (PK), acetyl coenzyme A carboxylase (ACC) and fatty acid (FA) synthase expression, and a decrease in pyruvate carboxylase (PyC) expression leading to an altered liver lipid profile. These parameters were normalized in the HF–SD group. The changes in lipogenic enzyme expression were parallel to changes in AktPKB phosphorylation status and nuclear expression in carbohydrate-response element and sterol regulatory element binding proteins. In conclusion, an HF–RD diet during pregnancy translates to changes in liver signaling and metabolic pathways in o spring, enhancing liver lipid storage and synthesis, and therefore non-alcoholic fatty liver disease (NAFLD) risk. These changes can be corrected by feeding an HF–SD diet during pregnancy. ; This research was funded by the European Union's Seventh Framework Programme (FP7/2007–2013): project EarlyNutrition, under grant agreement no. 289346.
