The Lower to Middle Paleolithic transition (~400,000 to 200,000 years ago) is marked by technical, behavioral, and anatomical changes among hominin populations throughout Africa and Eurasia. The replacement of bifacial stone tools, such as handaxes, by tools made on flakes detached from Levallois cores documents the most important conceptual shift in stone tool production strategies since the advent of bifacial technology more than one million years earlier and has been argued to result from the expansion of archaic Homo sapiens out of Africa. Our data from Nor Geghi 1, Armenia, record the earliest synchronic use of bifacial and Levallois technology outside Africa and are consistent with the hypothesis that this transition occurred independently within geographically dispersed, technologically precocious hominin populations with a shared technological ancestry.

Article Synopsis
- The dispersal of Homo sapiens during MIS 3 in the Late Pleistocene, characterized by technological changes known as Initial Upper Paleolithic (IUP), is examined through excavations at Bacho Kiro Cave in Bulgaria.
- Excavations from 2015 to 2021 uncovered over 2,000 lithic artifacts dated between 45,040 and 43,280 cal BP, alongside fauna remains and human fossils, revealing insights into the raw material use and lithic production techniques.
- Analysis of the lithics indicates long-distance mobility for raw materials, evidence of advanced knapping techniques, and on-site tool curation, contributing to a better understanding of lithic economies across different IUP
Deep-rooted Indian Middle Palaeolithic: Terminal Middle Pleistocene lithic assemblage from Retlapalle, Andhra Pradesh, India.

Article Synopsis
- The Indian Middle Palaeolithic is key to understanding early Homo sapiens' behavior and has been dated further back to the Middle Pleistocene, suggesting its development from the Late Acheulian culture.
- Recent research shows that this culture was resilient through major climate changes, including the Toba super-eruption about 74,000 years ago, highlighting its complexity.
- The study of artefacts from Retlapalle in Andhra Pradesh revealed a burial age of approximately 139,000 years and showcased a variety of advanced tools, adding important information to the relatively unexplored field of Middle Pleistocene archaeology in India.

The evolution of Paleolithic stone tool technologies is characterized by gradual increase in technical complexity along with changes in the composition of assemblages. In this respect, the emergence of retouched-backed tools is an important step and, for some, a proxy for "modern" behavior. However, backed tools emerge relatively early and develop together with major changes in Middle-Upper Pleistocene stone tool technologies.

Article Synopsis
- - The traditional healthcare approach often overlooks patients' personal experiences and strengths, focusing mainly on disease treatment. Person-centered care aims to align medical decisions with individual values and preferences, particularly for those with chronic conditions.
- - This paper seeks to enhance care for rhinitis and asthma by developing digital care pathways and incorporating real-world evidence to create a more patient-centered approach.
- - Key components of the review include advancements in mHealth, the integration of artificial intelligence, a novel classification system for airway diseases, and proposals for the ARIA 2024 guidelines, all targeting a sustainable and applicable healthcare model.
