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 six-year-old girl in Kerala’s Malappuram district sadly died of rabies even after getting preventive vaccination, highlighting a serious public health concern. Rabies is a fatal zoonotic disease caused by the Rabies virus (RABV), which attacks the nervous system. Rabies virus is an RNA virus from the rhabdovirus family and spreads in two main ways in the body. It can directly enter the peripheral nervous system and reach the brain. Or it can first hide and multiply in muscle tissue, then move into the nervous system through neuromuscular junctions. Once in the brain, it causes severe and deadly inflammation.

Notes:
Bodofa Upendranath Brahma was a respected leader of the Bodo community who championed non-violent struggle for tribal identity, rights and cultural preservation. On May 1, 2025, the Government of India (GoI) unveiled his 9-feet-high statue in New Delhi, marking his 35th death anniversary. Union Home Minister (UHM) Amit Shah presided over the unveiling and announced the naming of a major road and rotary after him. This tribute underscores the Government of India’s commitment to tribal empowerment and peacebuilding in India’s North East.

Notes:
Nepal has introduced a new draft law to allow only experienced climbers, who have scaled peaks above 7,000 metres, to attempt Mount Everest. This step comes in response to rising deaths, overcrowding, and environmental damage on the world’s tallest mountain. By restricting access, Nepal hopes to improve climber safety and promote responsible tourism. The law aims to ensure that only skilled mountaineers with proven high-altitude experience undertake such risky expeditions. The move also supports environmental conservation by addressing waste buildup and uncontrolled tourist flow in the fragile Everest ecosystem. This reflects Nepal’s growing commitment to sustainable mountaineering practices.

Notes:
The Indo Tibetan Border Police (ITBP) recently scaled Mt. Makalu, the fifth highest mountain in the world. Mt. Makalu stands at 8,485 meters above sea level and is located in the Mahalangur range of the Nepal Himalayas on the Nepal-Tibet border. It lies 23 kilometers southeast of Mount Everest and is part of the Makalu Barun National Park. The mountain is famous for its pyramid-like shape with sharp ridges and includes two subsidiary peaks, Makalu I and Makalu II.

Notes:
Reliance NU Suntech recently signed a 25-year Power Purchase Agreement with the Solar Energy Corporation of India Limited (SECI) to build Asia’s largest single-location integrated solar and Battery Energy Storage System (BESS) project. SECI is a Central Public Sector Undertaking (CPSU) under the Ministry of New and Renewable Energy (MNRE), dedicated to expanding Renewable Energy (RE) in India. SECI was formed in 2011 as a not-for-profit company and later became a commercial entity in 2015. It was established to support the National Solar Mission and has Miniratna Category-I status. SECI acts as the main agency for implementing solar, wind, and hybrid energy projects across India. It also helps fulfill India’s Nationally Determined Contributions (NDCs) by inviting developers through tenders for RE projects.

Notes:
A new non-contact wearable device developed by researchers from the United States and South Korea can monitor health by measuring skin flux without touching the skin. The device is about the size of a smartphone and tracks molecular movements like vapour leaving the body and chemicals entering through the skin. It was developed under the leadership of Professor John A. Rogers at Northwestern University, USA. It creates a small sealed microclimate next to the skin and uses wireless electronics and tiny sensors to detect water vapour, carbon dioxide (CO₂), and volatile organic compounds (VOCs). A remote-controlled valve adjusts the chamber’s openness for accurate comparisons.

Notes:
The Archaeological Survey of India (ASI) has decided to begin repair work on the damaged mihrab structure around the old water tank at Safa Masjid in Ponda, Goa. Safa Masjid, also called Safa Shahouri Masjid, is a historic mosque built in 1560 by Sultan Adil Shah of Bijapur. It is one of the few Islamic monuments in Goa that survived the Portuguese colonial period, during which many religious sites were destroyed. The mosque is known for its architectural and cultural value and is declared a national monument under the protection of ASI. The recent decision by ASI follows months of delay and brings hope for the preservation of this heritage site.

Notes:
In a recent statement, the Organization of Islamic Cooperation (OIC) expressed concern over the rising tensions between India and Pakistan and urged both sides to exercise restraint and engage in dialogue. The Organization of Islamic Cooperation (OIC) is the second largest intergovernmental group after the United Nations, with 57 member countries across four continents. It was founded on 25 September 1969 in Rabat, Morocco, following the arson attack on the Al-Aqsa Mosque in Jerusalem. The OIC works to protect Islamic values and the sovereignty and independence of its member states. It also aims to promote peace, security, and cooperation in political, economic, and social matters. The OIC acts as the unified voice of the Muslim world on global issues. Its headquarters is in Jeddah, Saudi Arabia, and its official languages are Arabic, English, and French.

Notes:
Rangacherra village in Tripura has become the first green village of the state due to the state government’s efforts. The Tripura Renewable Energy Development Agency (TREDA) implemented the green village project with a cost of Rs. 1.25 crore. A solar power plant and solar water purifier systems were installed in the village under Mohanpur subdivision. TREDA also provided solar home lighting systems to village households. The solar plant is connected to the grid of Tripura State Electricity Corporation Limited and supplies excess power to the state grid. Villagers, many of whom migrated from Jharkhand and Bihar, now get clean drinking water from a solar water purification system.
