Earth's biodiversity is central to ecosystem health and resilience, providing essential functions and services. The Red Sea is a recognised marine biodiversity hotspot with high endemism and unique environmental conditions that support extensive but poorly resolved biodiversity. Here, we applied metagenomic analyses to sediment samples collected from coastal to deep‐sea environments during the Red Sea Decade Expedition 2022 to...

Stromboli volcano (Italy) exhibits a persistent, low-intensity activity, but can occasionally produce more powerful eruptions. These paroxysms can generate pyroclastic density currents usually confined in the Sciara del Fuoco, a horseshoe-shaped depression about 2 km from inhabited areas. However, at least twice in modern times (1930 and 1944), PDCs occurred outside the Sciara del Fuoco, rising the hazard impact. This study fo...

Reconstructing the eruptive history of Antarctic volcanoes is often challenging due to limited outcrops exposure, extensive ice cover, and extreme environmental conditions. Here, we present detailed volcanological, textural, and geochemical analyses of three tephra layers (DPT 1, DPT 2, and DPT 3) from an englacial ice sequence at 2581 m asl on the southwest flank of Mount Melbourne, northern Victoria Land (Antarctica). Using...

The Iron Age was a period of change, with many innovations in the glass-making technology. The chemical composition of the set of objects considered in the present study demonstrates the diversity of the raw materials used and the depth of knowledge about the manipulation of glass appearance in the eighth-sixth centuries BCE. The study was carried out using fibre optics reflection spectroscopy and portable X-ray fluorescence s...

One of the more obscure areas of Roman Republican early coinage are debased quadrigati, which traditionally are deemed to represent the last stage of this coin type. Starting from a pre-screening, based on low specific gravity samples, we first performed neutron diffraction analyses on a larger sample, which allowed us to single out the more debased series. Subsequently, we focused on those series and applied various additiona...

The antimicrobial and immunostimulant proprieties of aromatic plant extracts have been widely described, but their effects on serum blood biochemistry in fish have not. For this study, we assessed the changes in serum blood biochemical parameters in rainbow trout fed with a fish diet supplemented with a basil supercritical extract (F1-BEO). Our hypothesis was that treatment and time would be associated with changes in 10 serum...
