Cultural and artistic mobilization in contemporary techno-political movements
La cultura y el arte son herramientas movilizadas por los movimientos sociales para enmarcar la acción colectiva. Los movimientos utilizan y recombinan los distintos elementos del stock cultural, tanto de la cultura popular como de la cultura mediática, y también crean elementos nuevos. A través de un proceso de mediación los movimientos influyen también en la industria cultural. A través de entrevistas y observación participante, este texto ilustra algunos ejemplos de movilización del arte y la cultura en los movimientos contemporáneos y define una cultura digital global de movilización ligada a la cultura de internet, tratando de delimitar las causas del surgimiento de esta cultura digital global compartida por diversos movimientos contemporáneos.Culture and art are tools mobilized by social movements to frame collective action. The movements use and recombine the different elements of the cultural stock, part of the popular culture as well as the media culture, and also create new elements.

La comunicación digital de Médicos Sin Fronteras en España durante la crisis de la COVID-19
This article analyzes the digital communication of Médecins Sans Frontières (MSF) during its intervention in Spain due to the emergency caused by COVID-19. Using content analysis techniques, the text engages with a number of the messages posted on the MSF website, emails sent to partners and publications on Facebook and Twitter. The material (a total 58 messages) is categorized by subject, sender, format, and objective, as well as the presence of informative or emotional approaches. Complementarily, items such as intensity, positive or negative undertones and the terms most frequently used are also examined. Our conclusion points towards the use of digital communication with a view to reinforce MSF's public image as an entity specialized in health care in emergency situations. The unprecedented intervention in Spain during the COVID-19 crisis has also shown MSF to be accountable to its audiences, showing how the organization usually works in other countries.Este artículo analiza la comunicación digital de Médicos Sin Fronteras durante su intervención en España a causa de la emergencia provocada por la COVID-19. Mediante un análisis de contenido de los mensajes publicados en su página web, los correos enviados a sus socios y sus publicaciones en Facebook y Twitter, categorizamos las temáticas, objetivos, enfoques informativos o emocionales, el emisor o el formato de una muestra de 58 mensajes. De forma complementaria, consideramos la intensidad, la dirección positiva o negativa o los términos más frecuentemente utilizados. Concluimos señalando cómo MSF ha enfocado su comunicación durante la crisis en explicar al público su intervención en España como forma de reforzar su imagen y sus atributos como una entidad especializada en la atención sanitaria en situaciones de emergencia. La inédita intervención en España ha servido a MSF para rendir cuentas a sus públicos mostrando la forma en la que habitualmente actúa en otros países
Imaginarios activistas sobre Internet: Del mito tecno-utópico al desencanto digital
Este artículo explora los mitos e imaginarios sociales sobre Internet compartidos y vehiculados por el discurso académico y por los activistas de los nuevos movimientos sociales que utilizan la tecnología de forma intensiva como base de sus estrategias de organización y acción colectiva. Se indagan los discursos, imaginarios y mitos sobre la Red mediante una metodología cualitativa basada en la observación participante y en la entrevista activa a activistas de diferentes movimientos sociales. A través del análisis de los relatos de los ciberactivistas recogidos entre 2007 y 2020, se manifiesta una evolución de los mitos e imaginarios, que transitan desde una retórica ciber-libertaria utópica e idealizada hacia una creciente desmitificación de la Red como espacio distópico
Multidisciplinary Scientific Cruise to the Northern Mid-Atlantic Ridge and Azores Archipelago
This work presents the preliminary result of the multidisciplinary cruise EXPLOSEA2
surveying the northern Mid-Atlantic Ridge and Azores Archipelago from 46 300 N to 38
300 N aboard the R/V Sarmiento de Gamboa and ROV Luso over 54 days (June 11 to
July 27, 2019). In this cruise report, we detail the geophysical, hydrographic, geological,
oceanographic, ecological, and microbiological data acquired and a brief of main
findings. The cruise addressed the exploration and comprehensive characterization
of venting sites, including the water column, the sediments and rocks that host the
hydrothermal activity, and the associated mineralizations, biology, and microbiology.
Deep hydrothermal chimneys and massive sulfide deposits (up 3,000 m in depth) within
the Moytirra hydrothermal active field were identified on slopes that had not been
explored previously. Another striking finding made during the EXPLOSEA2 cruise was
the field of carbonate chimneys named the “Magallanes-Elcano” field, a potentially relict
ultramafic-hosted hydrothermal site sourced by abiotic methane. This field is related to a
serpentinite and gabbro rock outcropping on a dome-shaped massif named the “Iberian
Massif.” An outstanding finding of the EXPLOSEA2 survey was the identification of the
first garden of soft corals growing after active submarine eruptions were reported in the
Azores Archipelago composed by a high density of soft corals the suborder Alcyoniina
at the summit and flanks of a recent volcanic cone at 160 m water depth developed
during the 1957–1958 eruption of Capelinhos. Several cold-water coral habitats formed
by colonial scleractinians (e.g., Lophelia pertusa and Madrepora oculata), coral gardens
composed of mixed assemblages of black corals (Leiopathes sp.), and octocorals and
dense aggregations of the glass sponge Pheronema carpenteri that may be classified as vulnerable marine ecosystems (VMEs) have been discovered during the EXPLOSEA2
cruise along the northern Mid-Atlantic Ridge. This work reveals the importance of
multidisciplinary surveys to the knowledge of deep-sea environments
High-resolution multibeam bathymetry of the northern Mid-Atlantic Ridge at 45–46° N: the Moytirra hydrothermal field
This work presents a new high-resolution multibeam bathymetric map of a segment of active deep sea-floor spreading in the Atlantic Ocean, the northern Mid-Atlantic Ridge (MAR) at 45–46º N. New high-resolution bathymetry data were acquired using an Atlas multibeam echosounder onboard the research vessel Sarmiento de Gamboa during the EXPLOSEA-2 survey in 2019. The final map of the MAR (50 m cell grid size) at the original scale of 1:200,000 shows a segment of 140 × 35 km of the MAR, at water depths from 715 to 3700 m. This new high-resolution bathymetric map allows to better defining the submarine morphology of the Moytirra hydrothermal active field, the only high-temperature field identified between the Azores Archipelago (Portugal) and Iceland. ROV submarine observations reaching the deepest part of the system for the first time show giant anhydrite-sulfide chimneys up to 20 m high, active strong black smokers and polymetallic massive sulfides
Clonal chromosomal mosaicism and loss of chromosome Y in elderly men increase vulnerability for SARS-CoV-2
The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) had an estimated overall case fatality ratio of 1.38% (pre-vaccination), being 53% higher in males and increasing exponentially with age. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, we found 133 cases (1.42%) with detectable clonal mosaicism for chromosome alterations (mCA) and 226 males (5.08%) with acquired loss of chromosome Y (LOY). Individuals with clonal mosaic events (mCA and/or LOY) showed a 54% increase in the risk of COVID-19 lethality. LOY is associated with transcriptomic biomarkers of immune dysfunction, pro-coagulation activity and cardiovascular risk. Interferon-induced genes involved in the initial immune response to SARS-CoV-2 are also down-regulated in LOY. Thus, mCA and LOY underlie at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential therapeutic and prognostic relevance, evaluation of clonal mosaicism should be implemented as biomarker of COVID-19 severity in elderly people. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality
