The summit is themed “Create in India, Create for the World” to position India as a global creative powerhouse.

Notes:
Researchers at the Institute of Nano Science and Technology (INST), Mohali, have found a new way to improve green hydrogen production. They created a special heterostructure using Copper Tungsten Oxide and Copper Oxide. This structure uses the Built-In Electric Field (BIEF) effect to boost the Hydrogen Evolution Reaction (HER). The Copper Tungsten Oxide nanoparticles are grown over a Cu(OH)₂ base, forming a p-n heterojunction with an uneven electronic setup. This BIEF helps in better proton adsorption and desorption. Green hydrogen, made from water using clean energy, is a pollution-free fuel of the future.

Notes:
A recent study by the Global Antibiotic Research and Development Partnership (GARDP) showed that many multidrug-resistant infections in low- and middle-income countries, including India, are not being treated properly due to lack of access. GARDP is a not-for-profit organization that creates new antibiotic treatments for drug-resistant bacterial infections and ensures they reach people in need. It focuses on public health by developing antibiotics to fight the current antimicrobial resistance (AMR) crisis and protect future generations. GARDP was founded by the World Health Organization (WHO) and Drugs for Neglected Diseases initiative (DNDi) under the Global Action Plan on AMR in 2015.

Notes:
Maharashtra has topped the CareEdge State Ranking Report 2025, released by CARE Ratings Ltd (CareEdge Ratings). This is the second edition of the CareEdge State Rankings. The rankings evaluate state performance across seven key pillars: economic performance, fiscal management, infrastructure development, financial sector growth, social development, governance quality, and environmental sustainability. The evaluation uses 50 measurable indicators. The primary aim is to provide a data-driven assessment of state performance. The rankings help identify strengths, gaps, and opportunities for policy improvement. This report offers valuable insights for improving state governance and development strategies.

Notes:
The European Red Admiral butterfly, scientifically called Vanessa atalanta, has been recorded for the first time in India near Dharamshala, Himachal Pradesh. This rare sighting was confirmed during a butterfly survey at Thatharna Hill in the Dhauladhar mountain range, at an altitude of 2,500 metres. The observation was verified by Himalayan butterfly expert Lovish Garlani from the Himachal Pradesh Forest Department. This raises the total number of butterfly species in Himachal Pradesh to 440, highlighting the region’s rich biodiversity. The species is known for long migrations across Europe and North America and was last seen in South Asia in 2022 in Pakistan after a 93-year gap. It has no confirmed records from China, Mongolia, or Afghanistan, making its presence in India a significant eastward range expansion.

Notes:
The United States has recently approved a military hardware and logistics support package for India to assist in the Integrated Platform for Maritime Domain Awareness (IPMDA). IPMDA is a technology and training initiative designed to boost maritime domain awareness in the Indo-Pacific region and increase transparency in its vital waterways. It was announced by the Quadrilateral Security Dialogue (QUAD), which includes India, Australia, Japan, and the United States, during the Tokyo summit in 2022. The initiative uses innovative technology to provide near real-time information on maritime activities to partners in Southeast Asia, the Indian Ocean region, and the Pacific.

Notes:
The International Monetary Fund (IMF) recently projected that global public debt may surpass the COVID-19 pandemic level of 98.9% of Gross Domestic Product (GDP) recorded in 2020. Sudan now has the highest debt-to-GDP ratio in the world at 252%, due to long-term conflict and economic struggles. Among developed countries, Japan ranks second with a debt-to-GDP ratio of 234.9%, mainly due to fiscal deficits and an ageing population. The United States ranks eighth with a ratio of 123%, while France and Canada follow with 116.3% and slightly lower respectively. China ranks 21st globally with a public debt ratio of 96%, which is lower than many advanced economies. India stands at 31st with a debt-to-GDP ratio of 80%, and the central government aims to reduce it to 50±1% by March 31, 2031.

Notes:
Eight Gram Sabhas in Baipariguda block, Koraput district, Odisha, have harvested over 4 lakh bundles of kendu leaves in the 2025 season and are waiting for government notification to deregulate the trade. These communities are pushing to manage and sell kendu leaves under the Forest Rights Act (FRA), 2006. Kendu leaf, also known as Tendu leaf, is a vital non-wood forest product and is referred to as the “Green Gold of Odisha.” It is a major forest product in states like Madhya Pradesh, Chhattisgarh, Odisha, and others. Under the FRA, forest-dwelling communities have rights to collect, use, and sell minor forest products like kendu leaves.

Notes:
A research team from the Hong Kong University of Science and Technology (HKUST) has made the first-ever experimental observation of a two-dimensional layered altermagnet at room temperature. Altermagnets are a new class of antiferromagnetic materials that show momentum-dependent spin splitting without needing spin–orbit coupling (SOC) or overall magnetization. This spin splitting is caused by exchange interactions between magnetic sublattices connected by crystal symmetry, known as C-paired spin-valley locking (SVL). Altermagnets combine the stable spin properties of antiferromagnets with spin-split energy bands, making them promising for next-generation spintronic devices.

Notes:
India has recently received a new shipment of Russian Igla-S air defence missiles amid rising tensions with Pakistan after the Pahalgam terror attack. Igla-S is a Man Portable Air Defence System (MANPADS) developed by Russia. It is a hand-held system that can be used by one person or a small crew. It is designed to shoot down low-flying aircraft, cruise missiles, and drones.
