Creencias de estudiantes de una universidad pública chilena sobre género y ciencia: resultados del curso Diálogos sobre Género y Ciencia Sotelo, Emanuel; Morales, Hortensia S. El presente estudio tiene por objetivo analizar las creencias de estudiantes universitarios en torno a la relación entre género y ciencia, a partir de su participación en el curso Diálogos sobre Género y Ciencia en la Educación Superior. La investigación surge ante la necesidad de incorporar la perspectiva de género en la enseñanza científica, considerando que las universidades continúan reproduciendo desigualdades y sesgos estructurales que inciden en la formación del estudiantado. Se adoptó una metodología cualitativa de tipo exploratorio-descriptivo, basada en el análisis de contenido temático de los comentarios reflexivos escritos por 18 estudiantes de distintas carreras al finalizar cada una de las once sesiones del curso. Estos registros fueron sistematizados e interpretados a partir de categorías emergentes que reflejan las percepciones, aprendizajes y tensiones manifestadas durante la experiencia formativa. Los resultados evidencian cinco ejes principales: la visibilización de mujeres en la ciencia, la crítica al androcentrismo, la valoración de la educación sexual integral como dimensión pedagógica, las resistencias culturales frente al feminismo y el reconocimiento de la interseccionalidad en los procesos de construcción del conocimiento. En conjunto, los hallazgos muestran que las creencias estudiantiles constituyen un espacio de transformación donde convergen reflexión crítica y resistencia social. Se concluye que promover instancias curriculares que articulen género y ciencia fortalece una enseñanza universitaria más equitativa y fomenta la alfabetización científica con enfoque inclusivo.; The present study aims to analyze university students’ beliefs regarding the relationship between gender and science, based on their participation in the course Dialogues on Gender and Science in Higher Education. This research emerges from the need to integrate a gender perspective into science teaching, acknowledging that universities continue to reproduce structural inequalities and biases that affect students’ academic formation. A qualitative exploratory-descriptive methodology was adopted, employing thematic content analysis of reflective comments written by 18 students from diverse academic programs at the end of each of the eleven sessions. These reflections were systematized and interpreted through emergent categories that captured students’ perceptions, learning processes, and social tensions expressed during the experience. The findings revealed five main thematic axes: the visibility of women in science, critique of androcentrism, recognition of comprehensive sexuality education as a pedagogical dimension, cultural resistances to feminism, and the acknowledgment of intersectionality in the construction of knowledge. Overall, the results suggest that students’ beliefs constitute a transformative space where critical reflection and social resistance converge. It is concluded that curricular experiences linking gender and science strengthen a more equitable approach to university teaching and promote scientific literacy with an inclusive perspective.

Sobre música, un artefacto poético y otras cosas: un día con Nicanor Parra Valdebenito Cifuentes, Nelson Mauricio Este escrito se basa en una experiencia personal y da como resultado un objeto material. La comprensión de las posibilidades interpretativas del objeto hace inevitable su relación con mi memoria. Se trata de una trama en que diferentes circunstancias coinciden para que tres personas acuerden encontrarse con motivaciones diferentes. De esta forma, y como resultado no previsto, resulta un objeto de tal riqueza que aquí será relatado desde diferentes perspectivas, en tanto objeto, cosa, mensaje, artefacto, música y literatura.

Aloe vera reduces gut inflammation induced by soybean meal in Atlantic salmon (Salmo salar) Fehrmann Cartes, Karen Inger; Vega, Matías; Vera, Frank; Enríquez, Ricardo; Feijoó, Carmen G.; Allende Connelly, Miguel Luis; Hernández, Adrián J.; Romero, Alex Plant-based protein sources, such as soybean, are widely used in fish nutrition due to their market availability, wide distribution and acceptable nutritional quality. However, in some fish species, soybean meal-based diets cause gut inflammation, decreasing both nutrient absorption and growth rates. A suitable alternative to avoid these problems could be the application of additives with anti-inflammatory activity to the diet. In this study, an Aloe vera (Aloe barbadensis Miller, AV) extract was analyzed as a dietary additive to reduce the gut inflammation in Atlantic salmon (Salmo salar) fed with soybean meal (SBM) diet. Fish were distributed in four duplicated groups and fed 28 days with fish meal control diet (FM), AV inclusion diet (AV), FM diet supplemented with AV (FM+AV), SBM diet to induce enteritis and SBM+AV. The fish gut response to these treatments was analyzed in distal intestine by histopathological scores, tissue morphometric measurements and immune gene expression parameters. The score results in fish fed with SBM-based diet clearly showed enteritis, meanwhile fish fed with AV supplemented diet significantly reduced the intestinal SBM signs of damage. These findings were associated to reduction of goblet cells number, lamina propria thickness and sub-epithelial mucosa size, with a significant decrease on pro-inflammatory cytokine il-1b to basal levels, similar to those present in fish fed FM diets. In conclusion, the administration of AV in salmon diet showed a protective intestinal activity against the detrimental effects of SBM, opening the possibility to improve its use as a feed additive in aquafeeds.

Variation in thermal tolerance of the giant kelp's gametophytes: suitability of habitat, population quality or local adaptation? Becheler, Ronan; Haverbeck, Daniela; Clerc, Corentin; Montecinos, Gabriel; Valero, Myriam; Mansilla, Andrés; Faugeron, Sylvain Wielfrid The giant kelp Macrocystis pyrifera is a cosmopolitan species of cold-temperate coasts. Its South-American distribution ranges from Peru to Cape Horn and Argentina, encompassing a considerable temperature gradient, from 3 to 20°C. Temperature is known to strongly affect survival, growth and reproduction of many kelp species, and ongoing global warming is already eroding their range distribution. Their response to thermal variability was shown to vary among genetically differentiated regions and populations, suggesting a possible adaptive divergence in thermal tolerance traits. This study aimed at testing the existence of local adaptation in the giant kelp, in regions separated by up to 4000km and strong thermal divergence. Two complementary experiments mimicked reciprocal transplants through a common garden approach, each habitat being represented by a given temperature corresponding to the regional average of the sampled populations. Several proxies of fitness were measured in the haploid stage of the kelp, and sympatric versus allopatric conditions (i.e. individuals at the temperature of their region of origin versus in a different temperature and versus individuals from other regions in that temperature) were compared. Additionally, a heat wave at 24°C was applied to measure the tolerance limits of these gametophytes. A significant interaction between experimental temperature and region of origin revealed that temperature tolerance varied among regions. However, depending on the fitness parameter measured, high latitude populations from the sub- Antarctic region were not always less heat resilient than populations from the warmer region of Peru. Even at 24°C, a temperature that is exceptionally reached in the southernmost part of the kelp’s natural habitat, all the gametophytes survived, although with strong differences in other traits among regions and populations within regions. This large range of temperature tolerance supports the idea of kelp gametophytes being a resistant stage. Finally, local adaptation sensu stricto was not detected. Fertility was more influenced by the geographic origin than by temperature, with possible effects of marginal conditions at the extremes of the distribution range. The latter results also suggest that stochastic dynamics such as genetic drift restricts adaptive processes in some populations of M. pyrifera.
