Chaetognaths, with their characteristic grasping spines, are the oldest known pelagic predators, found in the lowest Cambrian (Terreneuvian). Here, we describe a large stem chaetognath, gen. et sp.

- The study examined how the growth of Pinus heldreichii, a pine species, responds to varying air temperatures across different elevations in the southern Italian Apennines.
- Researchers conducted fieldwork over three years, collecting wood cores from 214 trees to assess growth patterns and climatic influences using a combination of tree-ring analysis and genetic methods.
- The findings revealed a bell-shaped relationship between tree growth and air temperature, with increased growth at higher elevations linked to warmer temperatures, as well as a strong positive correlation between growth and April mean temperatures, indicating the trees' ability to acclimate to changing climatic conditions.
Opsins are G-coupled receptors playing a key role in metazoan visual processes. While many studies enriched our understanding of opsin diversity in several animal clades, the opsin evolution in Lophotrochozoa, one of the major metazoan groups, remains poorly understood. Using recently developed phylogenetic approaches, we investigated the opsin evolution in 74 lophotrochozoan genomes.

February 2023
Background: Data from literature confirmed the non-trivial risk associated with carotid revascularization. The purpose of this study is to evaluate carotid endarterectomy (CEA) via a mini-invasive access (3-6 cm longitudinal) incision as a viable alternative to the traditional access via a cutaneous incision (˃6 cm) in terms of nerve sparing and neck pain/disability for patients.
Methods: We performed a prospective, observational, cohort study on 796 consecutive patients who underwent CEAs.
