A previously unknown 19th-century transcript of the Prologue Life of Saint Simeon, housed in an uncataloged manuscript at Studenica Monastery (R7), reveals a concise hagiographic tradition distinct from earlier verse editions. Dated to November 1831 based on scribe records, this 'younger' version omits verses and emphasizes Simeon’s monastic foundations (Studenica and Hilandar monasteries) alongside miracles like myrrh streaming and grave healings. The study situates the transcript within manuscript traditions by analyzing textual peculiarities, providing a critical edition and translation of the prologue for the first time.

The Baikal Gigaton Volume Detector (Baikal-GVD), the largest neutrino telescope in the Northern Hemisphere, is making significant strides in the search for high-energy neutrinos—elusive particles whose cosmic sources remain unidentified. Currently operational with 2000 optical modules arranged on 64 strings, covering an effective volume of 0.4 km³, Baikal-GVD detects cascades with energies above 100 TeV. This summary reviews the scientific rationale behind the detector, its construction progress, and preliminary findings from the partially built experiment. As the telescope continues to expand, it promises to deepen our understanding of neutrino astrophysics and potentially uncover the origins of these high-energy particles.

Researchers have identified four new species of the amphipod genus <em>Bellorchestia</em> from Tasmania, Australia: <em>B. lutruwita</em>, <em>B. needwonnee</em>, <em>B. palawakani</em>, and <em>B. reliquia</em>. These discoveries expand the known biodiversity of coastal beach-dwelling crustaceans in the region, including within the UNESCO-listed Tasmanian Wilderness World Heritage area. The study provides distribution records based on extensive ecological surveys, updates the generic diagnosis for <em>Bellorchestia</em> following recent taxonomic revisions, and includes a key and field guide to assist in species identification. This work contributes to our understanding of amphipod diversity and conservation in Australian coastal ecosystems.

A new architectural intervention framework for historically sensitive contexts, particularly in UNESCO World Heritage Sites like Historic Cairo, has emerged from recent research. This approach goes beyond formalistic design principles by integrating socio-cultural and economic humanistic dimensions to guide the development of new structures within historic areas. The study analyzed a case project at MSA University in Cairo, which received international recognition for its seamless integration with the historic environment, to establish principles that address both physical and non-physical aspects of architectural intervention. It also evaluates whether existing local design guidelines adequately capture the complexities of blending new and historic buildings. The findings aim to inform decision-makers at all levels, enhancing the preservation and quality of historic built environments.

New genetic data reveal the distribution and contact zones of three distinct phylogenetic lineages of Arctic charr (Salvelinus alpinus) in the north of East Siberia, including the Putorana Plateau. The study identified haplotypes belonging to the Atlantic and Siberian subgroups of the Eurasian group on the Putorana Plateau, while the Khatanga River basin exhibited Atlantic subgroup haplotypes exclusively. In contrast, the Lena River delta showed both Siberian subgroup and Bering group haplotypes. These findings refine the known ranges of these lineages and highlight their sympatry in Taimyr water bodies, supporting the close relationship between Siberian subgroup charr across their distribution. The research analyzed mitochondrial DNA (mtDNA) control region sequences from 10 Arctic populations spanning from the Yenisei to the Lena rivers, providing critical insights into the genetic structure and evolutionary dynamics of this species in East Siberia.
