Molecular Ecology Resources, Volume 26, Issue 1, January 2026.ABSTRACT Environmental DNA (eDNA) analysis enables biodiversity monitoring by detecting organisms from trace genetic material, but high reagent costs, cold‐chain logistics and computational demands limit its broader use, particularly in resource‐limited settings.

Weaponising the Supply Chain: Yemen's Blockade and the Contradictions of Maritime Logistics Capital
Antipode, Volume 58, Issue 1, January 2026.Abstract This paper examines the 2023–2025 naval blockade imposed by Yemen in the Red Sea. It argues that the blockade's success in disrupting global trade stemmed from the potent confluence of asymmetric military tactics and the structural vulnerabilities inherent within global maritime logistics capitalism.

Journal of Management Studies, Volume 63, Issue 1, Page 1-21, January 2026.Abstract Entrepreneurship research has long focused on exceptional, high‐growth, venture‐funded firms while overlooking the everyday and modest ventures that make up most entrepreneurial activity. This Special Issue calls for a recalibration of the field by decolonizing its assumptions and embracing its pluralism.

Luminosity segregation in galaxy clusters as an indication of dynamical evolution [PDF]
Theoretical models describing the dynamical evolution of self-gravitating systems predict a spatial mass segregation for more evolved systems, with the more massive objects concentrated toward the center of the configuration. From the observational point

Molecular Ecology, Volume 35, Issue 1, January 2026.ABSTRACT Biological invasions are major drivers of recent biodiversity changes, yet the genetic structure and ecological mechanisms underlying invasion dynamics remain poorly resolved in invasive social insects. In South Africa, the European wasp Vespula germanica (Hymenoptera: Vespidae), introduced in the 1970s, has spread remarkably more slowly than ...

Dynamical friction and measurements of the splashback radius in galaxy clusters
The Open Journal of AstrophysicsThe splashback radius is one popular method of constraining the size of galaxy clusters, often measured through the logarithmic derivative of the galaxy number density profile.

Advances in Astronomy, Volume 2026, Issue 1, 2026.We examine the weak cosmic censorship conjecture (WCCC) violation by throwing a charged and rotating test particle into a Kerr–Newman–modified gravity black hole (KN–MOG BH). The result depends on several factors, such as the relative sign of the particle’s charge and its direction of rotation with respect to black hole (BH).

A Catalog of 1.58 Million Clusters of Galaxies Identified from the DESI Legacy Imaging Surveys
The Astrophysical Journal Supplement SeriesBased on the DESI Legacy Imaging Surveys released data and available spectroscopic redshifts, we identify 1.58 million clusters of galaxies by searching for the overdensity of the stellar mass distribution of galaxies within redshift slices around ...

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.This study explores the integration of deep learning technologies, specifically U‐Net based segmentation methods, for evaluating earthquake‐induced damages. The study leverages a dataset derived from the Kahramanmaraş earthquake to train and test deep learning models capable of identifying and quantifying structural damages such as concrete cracks. The
