Ankita Sharma A new species of Polyrhachis Smith from Garbhanga Reserve Forest, Assam, India, with a key to the Indian species of Polyrhachis mucronata group (Hymenoptera: Formicidae) http://www.asian-myrmecology.org/doi/10.20362/am.019001.html Sharma, A., Mangaly, P. A., Singha Deo, S. K., Sangavi, D., & Sinha, A. (2025). A new species of Polyrhachis Smith from Garbhanga Reserve Forest, Assam, India, with a key to the Indian species of Polyrhachis ... Asian Myrmecology, 19:019001. pp. 1-9. The study describes a new species of Polyrhachis, or spiny ant, named Polyrhachis garbhangaensis sp. nov., from the state of Assam, northeastern India. This species was collected and identified during field sampling in the Garbhanga Reserve Forest, near the city of Guwahati in Assam. It represents a third Indian species of the P. mucronata species group in the subgenus Myrmhopla. Polyrhachis Smith, 1857 is a genus of ants, found widely across the Old-World tropics, with significant diversity across Southeast Asia. The discovery and characterisation of this species clearly indicate the need to revise the classification key of the genus Polyrhachis. As a step towards this, we present an updated key to the species of the mucronata group of Polyrhachis (Myrmhopla), including the new species. This finding contributes to a deeper understanding of the taxonomic diversity of Polyrhachis and highlights the unexpected importance of urban and fragmented forest areas in sustaining tropical ant biodiversity. |

Rudrodip Majumdar Hydrogen Supply Chain Effectiveness: Conceptualizing Uncertainties Through Genetic Simulations https://www.igi-global.com/gateway/chapter/400594 Chhabra Nishtha, Rudrodip Majumdar, Tapasi Ghosh and T. Subramanyam (2026). In: AI and Sustainability for Global Security edited by Amal Jmaii. IGI Global Scientific Publishing, pp. 155-190. ISBN 9798337310770 The shift from carbonaceous sources to cleaner alternatives necessitates reorienting and optimizing energy supply chains. Despite technological advancements, energy security remains susceptible to disruptions caused by geopolitical tensions, resource constraints, and market fluctuations. This chapter explores how genetic simulations, leveraging metaheuristic optimization techniques, facilitate a trade-off between the resilience and cost-effectiveness of green hydrogen supply chains. A data-driven case study examines the first-level viability of the envisaged green hydrogen system, covering prominent pathways for production, storage, and transportation and distribution (T&D). Scenarios are ranked based on cost per tonne for production, storage, and T&D. Prima facie viable cases are further discussed considering supply chain vulnerability under geopolitical and logistical constraints. Such studies help strategize long-term energy security for developing economies like India. |

M Sai Baba The International Day of Women in Multilateralism https://niascomm.in/2026/01/25/the-international-day-of-women-in-multilateralism/ SciComm@NIAS Despite women's extensive participation in fields such as global health, education, and social services, significant disparities continue in leadership positions. Representation is necessary, but insufficient. Multilateralism adds the dimension of global influence, collaboration, and institution-building. This observation of "The International Day of Women in Multilateralism" is not merely ceremonial—it is a call to action. |
