Variation in the structure and size of the eye in relation to light environments is well-documented across animal taxa. However, the long-term effects of ultraviolet radiation (UVR) on eye size across generations remain understudied, despite natural fluctuations in UVR being common in aquatic habitats. Here, we used Daphnia magna to test whether an evolutionary history of UVR threat modifies plast
Since its inception in 1998, the Cuneiform Digital Library Initiative (https://cdli.earth) has become the global authority index for inscribed artifacts of the cuneiform world, providing an essential reference for a corpus of half a million historical documents that form an important part of the world’s written heritage. The CDLI infrastructure is now foundational to the study of the history of th
Key message: A candidate gene exhibiting pleiotropic effect on twelve different seed size and weight traits was identified through a combination of evidence from population genetic selection, GWAS, earlier QTL studies, transcriptome analysis, and transgenic analyses. Abstract: Peanut is an important oilseed crop. Seed weight and size significantly impact yield, leading to the identification of num
Few existing studies have delved into individual-level attitudes towards the exchange of sexual services for payment, leaving a significant gap in our understanding. Various studies have speculated about how certain demographic factors and attitudes may shape people's perceptions of causes and consequences relating to such exchanges, but none have directly investigated this topic. To bridge this g
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
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
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
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
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,
Nickel (Ni) is the key component in ohmic contacts for Mg-doped p-GaN, but the detailed formation mechanisms of the ohmic contact have not yet been understood. In this work, the effect of potassium hydroxide (KOH)-based chemical treatment on the surface of p-GaN is investigated using X-ray photoelectron spectroscopy (XPS), scanning tunneling microscopy (STM), and low-energy electron diffraction (L
This chapter examines how people associate various sex work activities with the exchange of sexual services for payment. It considers both in-person activities, such as sexual intercourse, oral sex, erotic massage, and dancing, as well as remote, digitally mediated activities like webcamming and the production of pornographic videos and photos. Drawing on an original US survey of adults (n = 1,024
Objective: To determine whether combining routine cross-cultural cognitive assessments with plasma phosphorylated tau217 (p-tau217) increases diagnostic accuracy in identifying Alzheimer's disease (AD) in a consecutive mixed memory clinic cohort of ethnically diverse patients. Methods: We included 201 memory clinic patients originating from 42 different countries. Patients were examined with the M
Aggregation of the hyperphosphorylated tau protein is a central driver of Alzheimer’s disease, and its accumulation exhibits a rich spatiotemporal pattern that unfolds during the course of the disease, sequentially progressing through the brain across axonal connections. It is unclear how this spatiotemporal process is orchestrated, namely, to what extent the spread of pathologic tau is governed b
Aqueous redox flow batteries (RFBs) as grid-scale energy storage devices hold great potential to accomodate the rising demand for intermittent renewable energy sources. A significant parameter that enhances the sustainability of RFBs is selecting the appropriate redox species. In this study, we investigated the application of lignosulfonate as a redox species for the negolyte of aqueous RFBs becau
BACKGROUND: Heart failure (HF) is characterized by hemodynamic derangements that are likely to mediate systemic metabolic perturbations but limited data are available. Plasma metabolite profiling provides opportunities for comprehensive investigation of such perturbations. Here, we aimed to characterize plasma profiles that associate with HF and their relationship with central hemodynamics, sympto
Within the stroma of pancreatic ductal adenocarcinoma (PDAC), mesenchymal cells differentiate into cancer-associated fibroblast (CAF) subtypes that differentially mediate disease progression. Defining the regulatory mechanism and diversity of CAF subtypes could identify potential therapeutic strategies to harness the tumor-suppressive activities of CAFs. To address this, we utilized single-cell RN
The Hjortspring boat is the only intact example of a prehistoric sewn plank boat ever found in Scandinavia. Built from lime wood planks lashed together with cordage, the boat represents the maritime technology used by some of Northern Europe’s earliest seafarers. This article reports new analysis of the cordage and caulking material used in the construction of the Hjortspring boat. We provide the
