Cretaceous sea turtle soft tissues clarify ancestry of scale loss in chelonioids

Scale loss is a quintessential hydrodynamic adaptation in marine reptiles, and paralleled the pelagic specializations of Mesozoic ichthyosaurs, plesiosaurs, and metriorhynchid crocodylians, as well as the modern Leatherback Sea turtle (Dermochelyidae). By contrast, modern hard-shelled sea turtles (Cheloniidae) retain both scutes and scaly flippers, despite evolving from among partially scale-less

Teaching sustainability - workshops – bridging real-world challenges from different systemic levels

To prepare students for addressing wicked problems such as climate change and inequality, higher education must foster systemic and interdisciplinary thinking. We developed a flexible, interactive workshop grounded in sustainability goals and transitions theory to promote abductive reasoning across disciplines. Using cases on food waste, fashion, and e-waste, the workshop was tested in four divers

Analysis of Droughts and Floods Evolution and Teleconnection Factors in the Yangtze River Basin Based on GRACE/GFO

In recent years, under the influence of climate change and human activities, droughts and floods have occurred frequently in the Yangtze River Basin (YRB), seriously threatening socioeconomic development and ecological security. The topography and climate of the YRB are complex, so it is crucial to develop appropriate drought and flood policies based on the drought and flood characteristics of dif

Symptoms and objective signs of peripheral sensory neuropathy in POTS and correlations to gastrointestinal symptoms

Aim Postural orthostatic tachycardia syndrome (POTS) is a disorder with cardiovascular autonomic dysfunction where multiple and variable symptoms are common, including those from the peripheral and enteric nervous systems. We aimed to investigate subjective and objective signs of small and large fiber neuropathy in a Swedish POTS cohort compared with healthy controls. Secondly, we wanted to examin

Lessons of history : Learning from catastrophe and crisis in twentieth-century Europe

Historical lessons are useful or even necessary for our guidance and orientation in time. These lessons, however, have often been overlooked in historical reflections on watershed moments, such as genocides, treaties, and global movements. Focusing on how cataclysmic events, primarily within Central and Eastern Europe, have been transmitted across borders and generations, this volume interrogates

The economic power of elites, human capital, and industrial change in late Imperial Russia

This paper studies the economic impacts of land ownership concentration among the aristocratic elite in the Russian Empire. I document that areas with a higher concentration of noble land ownership were associated with lower levels of primary education during 1880–1911. Exploring the mechanisms, I show that by controlling local governments the landed elites decreased public spending on education,

Factors associated with poor prognosis in elderly biopsy-only glioblastoma patients

Purpose: Glioblastoma (GBM) in elderly patients has a poor prognosis. About one-third of patients have impaired perioperative performance status (PS) and often excluded from clinical trials. Brain biopsy is the standard diagnostic approach when resection is not feasible. Previous studies on preoperative prognostic factors have mostly focused on resected patients. This study aimed to identify preop

How energy and chemistry converge for a fossil-free future

The chemical industry must undergo a dual transformation: electrifying energy use and defossilizing carbon feedstocks. This paper, developed by ENGIEs Scientific Council, examines how energy and chemistry can converge to enable this shift. We assess the roles of biomass, recycled plastics, and CO2 as sustainable carbon sources and explore the enabling potential of electrification, low-carbon hydro

Some issues of accessibility in online social services: direct access versus signposting

Easy and low-threshold access is considered to be a major advantage of online services. In Sweden, social services in several municipalities strive to increase their accessibility by responding to anonymous users online. This paper raises the question about the nature of accessibility that the online social services entail. Two online platforms were studied: synchronous online chats and asynchrono

Performing the Sacred/Secular Nation: The Centenary of Izmir as a Dynamic of Memory-Contest in Turkish Nationalism

How is Turkish official memory negotiated locally in Izmir, a city celebrated as a symbol of national becoming, yet (im)famous for its scepticism of central power? How is the past of the city narrated, conceived as an epitome of progress, yet built on a systematic forgetting of trauma and violence? And how does the secularist legacy of Izmir, accentuated in contrast with the Islamisation of memory

Triumph and Trauma: Commemorating the Conquest of Izmir in State and (Trans)Local Narrative

On October 29 2023, Turkey celebrates the centenary of the Republic. We may anticipate this to be an equally spectacular and politicized event: a purported celebration of national unity, which in essence will reproduce and re-affirm distinct political wedges. Carefully choreographed national celebration has a long history in Turkey. And historiography has been its narrative bedrock, highlighting t

Longitudinal Associations of Multimodal Core 1 Alzheimer Disease Biomarkers With Cognition in Aging and Preclinical Alzheimer Disease

BACKGROUND AND OBJECTIVES: Addressing the association between early-changing Alzheimer disease (AD) biomarkers and cognition is essential for characterizing preclinical AD. However, few studies have explored this relationship longitudinally, especially across multiple biomarker modalities. The aim of this study was to evaluate longitudinal associations of multimodal core 1 AD biomarkers with cogni

Learning at the edge : simulated DDoS detection in 5G networks

The growing use of 5G networks for critical services makes them vulnerable to Distributed Denial of Service (DDoS) attacks. While numerous Machine Learning (ML)-based approaches have been proposed, the real-world deployability of these models remains understudied. This work presents what is, based on existing literature, the first simulation-driven methodology to evaluate both the transferability

Overwriting Smyrna: Urban Imaginaries in Turkish-Nationalist Commemoration

Despite its importance for the establishment of modern Turkey, İzmir remains understudied in scholarship on Turkish nationalism. This paper presents data from the project Beyond Sacred/Secular Cities, studying urban imaginaries in contemporary Middle Eastern nationalisms. With a point of departure in theories of memory (Connerton 1989), postsecularism (Asad 2018), and social construction of space

Cardiovascular magnetic resonance as an initial screening tool in individuals with SLE and chest pain

Objective Individuals with SLE commonly report chest pain or discomfort. We performed cardiovascular magnetic resonance (CMR) to differentiate coronary artery disease (CAD), coronary microvascular dysfunction (CMD), pericarditis and myocarditis in individuals with SLE who presented with chest symptoms. We also assessed the clinical utility of CMR. Methods Adults with SLE were included if reporting

Comparison of sociodemographic factors, lifestyle, and gastrointestinal symptoms between patients with endometriosis and IBS

Objectives: Endometriosis and Irritable bowel syndrome (IBS) are two common diseases with overlapping symptomatology, causing confusion and delay in the diagnostic process. The objective of this study was to identify differences between endometriosis and IBS diagnosed according to Rome IV, by comparing sociodemographic factors, lifestyle habits, and gastrointestinal symptoms. Materials and methods

The Diversity and Evolution of Vocal Communication in Nonavian Reptiles

Historically, research on nonavian reptile communication has emphasized visual, tactile, and chemical modalities. Recently, growing evidence highlights the significance of acoustic signals in intra- and interspecies interactions. Reptiles produce sounds to mediate social behaviors such as reproduction, parent–offspring interactions, and territorial defense. Many species were found to have diverse

Unpacking climate effects on boreal tree growth : An analysis of tree-ring widths across temperature and soil moisture gradients

The effect of climate change on tree growth in boreal forests is likely mediated by local climate conditions and species-specific responses that vary according to differences in traits. Here, we assess species-specific tree growth responses to climate along gradients of mean annual temperature and soil moisture. We assessed growth-climate relationships by using tree-ring width data in Norway spruc
