Summary: Geochemical data from igneous rocks in northeastern North America and the British Isles spanning from Katian to earliest Emsian were compiled to identify tectono-magmatic events related to ocean closure and the formation of the Appalachian-Caledonian Belt. A model for Iapetus and Rheic ocean closure was proposed based on these data, which also revealed chronological trends in the geochemical signatures of the igneous rocks, aiding in understanding the tectono-magmatic events associated with ocean closure and the formation of the Appalachian-Caledonian Belt.

Summary: Crataegus laevigata is a shade-tolerant shrub or small tree native to central and northern Europe, traditionally used in herbal medicine and as food. Its fruit is primarily dispersed by birds and it easily hybridizes with other species.

Summary: This article provides a comprehensive overview of the biology of Crataegus monogyna, covering topics such as distribution, habitat, morphology, physiology, phenology, fruiting, herbivores and disease, history, and conservation. The species is native to the British Isles and is of both ornamental and ecological value, playing an important role in providing food and habitat for various insects and birds. Expert knowledge is necessary to distinguish between different Crataegus species due to hybridization and horticultural introductions, which can complicate identification in natural stands.

Summary: This article introduces a dataset of 1550 graptolite specimens, including high-resolution images and scientific information of each specimen. The dataset contributes to global bio-stratigraphic correlation and shale gas exploration, and provides a valuable resource for specialists and laypeople through the visualization of image data and exploration of similarities using t-SNE.

Summary: In the southern Appalachian region, it is recognized that Ordovician and Silurian siliciclastic, volcanic, and plutonic rocks are part of a paired arc/back-arc system that formed on the seaward edge of the Laurentian plate. New crystallization ages confirm rapid deposition in an Ordovician-Silurian extensional basin that received input from continentally derived Mesoproterozoic crust and bimodal volcanic components. The ages of zircons suggest a significant Mesoproterozoic component in the genesis of these rocks.

Summary: The study suggests that fluctuations in redox conditions, in addition to commonly cited thresholds of bimetal ratios, may have influenced the redox trends during the Ordovician-Silurian transitional interval. The strong correlation between changing redox conditions and fossil distributions implies that dynamic and ferruginous conditions contributed to biotic crises. The coupling of total organic carbon (TOC) and redox proxies highlights the importance of prolonged anoxia or euxinia in the accumulation and preservation of organic matter.

Summary: This study discusses the historical progression of cataract surgery in the British Isles, starting from possible Roman era couching to the popularity of couching in the 18th century. Cataract extraction began to gain traction in the mid-18th century, despite the ongoing popularity of couching.

Summary: This study reports a large and fast true polar wander event that occurred 450-440 million years ago and provides evidence based on paleomagnetic data and paleopoles from major continents. The study also suggests that this event can explain the migration of glacial centers and the mass extinction at the end of the Ordovician period.

Summary: The Late Ordovician mass extinction (LOME) occurred in two discrete pulses, linked to environmental stresses caused by the onset and termination of the Hirnantian Glaciation. Recent studies have suggested a potential connection between LOME and massive volcanism during the Ordovician-Silurian transition (OST), based on significant mercury anomalies in the South China region. However, the study finds that volcanic activity in South China during the OST was a regional phenomenon, and there is a discrepancy between the distribution of bentonite beds and the overall redox evolution in the region. Mercury isotope analysis suggests that seawater was the source of mercury enrichment during the OST. Therefore, the LOME may not have been caused by massive volcanism, but rather by long-term cooling, weathering, anoxia, and marine eutrophication.

Summary: This study presents continuous and well-constrained carbon isotope profiles in the Alum Shale Formation of southernmost Scandinavia. The profiles provide valuable markers for identifying global stage boundaries, including the Steptoean Positive Carbon Isotope Excursion (SPICE) event, the Top of Cambrian Excursion (TOCE), and the Cambrian-Ordovician Boundary Spike (COBS). These markers contribute to the understanding of Furongian carbon isotope chemostratigraphy and the correlation between different paleocontinents.

Summary: The Anatolide-Tauride block in the Tethyan belt was a passive northern continental margin of Gondwana in the Paleozoic era. A relatively large metaquartz-syenite to -granite complex was discovered in the Eastern Anatolia, with distinct igneous textures and geochemical characteristics typical of A-type syenite to granite. Isotopic analysis indicated a derivation from high-temperature mantle magmas without significant crustal assimilation. The Late Ordovician-Silurian A-type igneous rocks in this region were likely related to a rifting event at the northern margin of Gondwana, leading to the opening of the Paleo-Tethys.

Summary: This study reconstructs the sedimentary mechanisms of shale in the southern Sichuan Basin by combining logging, mineralogy, and geochemistry. The study found that the shale in the area can be divided into different sequences, which are influenced by factors such as volcanic eruption and glaciation, leading to different sedimentary environments and lithofacies. This has significant implications for the development and exploration of shale gas.

Summary: Molybdenum enrichment in Ordovician and Silurian stone coals in central China shows great potential as an alternative source of molybdenum, with concentrations 99 times higher than the global average. Future studies should focus on the ecological effects and cost savings of molybdenum extraction from stone coal.

Summary: A study on food protein-induced enterocolitis syndrome (FPIES) in the UK and Ireland found a lower incidence rate than expected, with most cases diagnosed near specialist allergy centers but experiencing delays in diagnosis. Education of healthcare professionals is needed to improve recognition, earlier diagnosis, and treatment of FPIES in frontline clinical settings.
