Significance
Influenza infection during pregnancy is associated with increased maternal and perinatal complications. Here, we show that, during pregnancy, influenza infection leads to viral dissemination into the aorta, resulting in a peripheral “vascular storm” characterized by enhanced inflammatory mediators; the influx of Ly6C monocytes, neutrophils, and T cells; and impaired vascular function. The ensuing vascular storm induced hypoxia in the placenta and fetal brain and caused an increase in circulating cell free fetal DNA and soluble Flt1 release. We demonstrate that vascular dysfunction occurs in response to viral infection during pregnancy, which may explain the high rates of morbidity and mortality in pregnant dams, as well as the downstream perinatal complications associated with influenza infection.
Rapid onsets of warming events trigger mass mortality of coral reef fish

Published: September 2020

Significance
Our study reveals a hitherto overlooked effect of warming on coral reefs. Traditionally, ecological studies of warming events focused on maximum temperatures and duration, rather than the rate of warming at the onset. Here, we show that onsets can trigger widespread mortality of reef fish. Hundreds of thermally stressed fish, belonging to dozens of species, became fatally infected with a common pathogen in the Red Sea. Differential susceptibility led to selective mortality, with disproportional death among predators and benthic feeders. A reassessment of past reports suggests that extreme onset might have been an overlooked trigger of fish kills elsewhere. Warming tropical and subtropical reefs may face an increasing frequency of extreme onsets, eliciting calamities far beyond coral bleaching.

Published: September 2020

Significance
Melatonin (Mel) promotes sleep through G protein-coupled Mel receptors. However, the downstream molecular target(s) of the Mel receptors to produce the sleep effect remains enigmatic. The study shows that a potassium channel, the BK channel, plays a role in sleep and that Mel promotes sleep by activating this channel through a specific Mel receptor.

SignificanceThe evolution of jaws in early vertebrates provided such a predatory advantage that 99% of vertebrate species living today are jawed. What is often overlooked, however, is another structural innovation that happened concurrently and may have been equally critical to the lineage’s success: the evolution of musculoskeletal gill covers to actively drive oxygenated water over the gills. Here, we identify the first essential gene for gill cover formation in modern vertebrates, Pou3f3, and uncover the genomic element that brought Pou3f3 expression into the pharynx more than 430 Mya. Remarkably, small changes in this deeply conserved sequence account for the single large gill cover in living bony fish versus the five separate covers of sharks and their brethren.
Unraveling nucleation pathway in methane clathrate formation
Authors: Li Liwen , Zhong Jie , Yan Youguo , Zhang Jun , Xu Jiafang , Francisco Joseph S. , Zeng Xiao Cheng 
Published: September 2020

Significance
Understanding the clathrate formation mechanism has important implications on natural gas exploitation, storage, and transportation. A key toward clathrate formation is the hydrate nucleation, which involves complex interplay between water and guest molecules at nanoscale and multiple kinetic stages. Herein, by tracing the kinetic evolution of multiple ternary water-ring aggregations based on trajectories of large-scale molecular dynamics simulations, we identified a generic nucleation pathway to clathrate formation. This observed nucleation pathway is driven by numerous compression/shedding processes among the methane hydration layers, and it can explain the widely accepted “blob” model of clathrate nucleation. The molecular insight into the nucleation pathway allows us to quantitatively assess the nucleation timescales as well as the critical nucleus sizes in the clathrate formation.
Translator training outdoors
Authors: Torres-Hostench Olga 
Published: September 2020

AbstractBefore the COVID-19 pandemic, there was no real need to integrate outdoor education into translation studies, as it was easy to balance indoor and outdoor time before and after translation classes. However, the lockdown has deeply affected not only learning but also the mental and physical health of teachers and students, and outdoor education may contribute to recovery afterwards. The proposals in this paper focus on the benefits that being outdoors has for physical health, knowledge, social relations, mental health and attitude to learning. Moreover, being outdoors allows for social distancing. The activities presented in this paper are related to specialized translation, sight translation, simultaneous interpreting, consecutive interpreting, role-play interpreting, translation theory, song translation, theatre translation, machine translation post-editing, translators’ employability, translation project management and, last but not least, intermodal transcreation.
Europeanisation from below: Still time for another Europe? Introduction to the special issue of the European Journal of Cultural and Political Sociology
Authors: della Porta Donatella 
Published: September 2020

ABSTRACT
The focus of this special issue is on social movements’ alternative visions and practices of ‘another Europe’. As trust in the European Union (EU) is dramatically falling amongst its citizens, research on alternative visions of Europe ‘from below’ appears all the more relevant in order to understand the potential for changes in EU politics, policies, and polity. The general question we want to address refers therefore to the ways in which the financial crisis and related political turmoil have affected the position of progressive social movements towards the Europeanisation process. In addressing the development of alternative visions of Europe, this special issue looks at anti-austerity protests, and related mobilisations in the period of 2011–2016. The various contributions assess the effects of the financial crisis on the multilevel governance of European countries and, therefore, on the ways in which social movements formulate claims, frames, and justifications about European institutions. This editorial introduces the main approaches to the Europeanisation of social movements, discusses how they might apply in times of crisis, and then presents the articles included in the special issue.

Abstract
Statistics are very important for students to master, but many experience difficulties. This study aims to determine the effectiveness of a combination of blended learning and problem based learning in improving student motivation, independence, and statistical learning achievement. This research is a quasi-experimental study conducted on IAIN Ponorogo students. The instruments used for data collection were achievement tests, learning independence tests, and learning motivation questionnaires. The data collected was analyzed using MANOVA and continued with the Bonferroni Test. The result of the MANOVA test has obtained a significance of 0.000 so that it can be concluded that the combination of blended learning and problem-based learning was more effective in increasing student motivation, independence, and statistical learning achievement than blended learning and problem based learning methods. Specifically, the combination method is more effective in increasing student learning motivation than blended learning and problem-based learning. In the aspect of increasing student learning independence, the combination method has the same effectiveness as problem-based learning. Both are more effective in increasing the independence of student learning than blended learning. Whereas in the aspect of learning achievement, the combination method is more effective in increasing student statistical learning achievement than blended learning and problem-based learning.

Authors: Tanujaya Benidiktus , Mumu Jeinne 
Published: September 2020

Abstract
The purpose of this lesson study was to improve learning activities of Mathematics instruction. Learning activities to be improved is the theory of probability. There are three phases on this lesson study, PLAN, DO and SEE. In PLAN cycle, the researcher organizes chapter design and lesson plan. In the Do cycle, the lesson plan was implemented in instruction using Think-Pair-Share model. Students are thinking individually before they were paired in groups. The teaching process is organized in two sequence classes. In the first lesson, the learning process was quite conducive, but it still needed some improvement. In cycle SEE, based on the observation of the first lesson, teachers are suggested to use more concrete-case examples to build students’ understanding of concepts for the next lesson. The teachers should ask more questions and pay attention to students who are less active during the class. The last recommendation is that students should analyse assignment independently before posing criticisms and providing suggestions to others. The second lesson shows that students are more active compared to the first lessons. Students have more relaxed learning atmosphere. They are more assertive and involved in whole class activities. The students are more confident to ask questions, give objections, and make some corrections.

Abstract
The main idea in this article is looking at the creative thinking patterns in mathematics learning viewed from gender on vocational high school students. Creative thinking skills are cognitive processes, and cognitive processes are inseparable from how the brain processes work. To see the ability to think creatively, we have to see how the process of creative thinking happens. This is a neuroscience study in mathematics with a quasi-experimental design. We tried to describe the relationship among neuroscience, mathematics creative thinking skills, and gender. We involved 30 male students (automotive major) and 30 female students (accounting major) from the 12th-grade of Islamic Center Vocational High School of Cirebon, West Java, Indonesia. Statistics test used was independent sample t-test to see about mean differences of males and female group. There are three indicators about mathematical creative thinking used are fluency, flexibility and novelty. Finally, we found that male students and female students have their own structure of the brain. Female student has a higher ability of mathematical creative thinking skills than male students in Islamic Centre Cirebon, West Java, Indonesia.
