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:
The National Archives of India (NAI) has added the private papers of former President Dr. A.P.J. Abdul Kalam to its rich collection, making a major contribution to India’s historical records. It works under the Ministry of Culture and stores old government records that are no longer active but important for research and administration. It is the largest archival repository in South Asia and protects records of lasting value to the Government of India. NAI was started as the Imperial Record Department on 11 March 1891 in Kolkata and moved to New Delhi in 1911. The full transfer of records to Delhi was completed in 1937. NAI also enforces the Public Records Act, 1993 and Public Record Rules, 1997. It preserves over 34 crore pages, including official files, maps, censuses, treaties, debates, rare manuscripts, and government documents.

Notes:
The Subaru Telescope in Hawaii recently used the Hyper Suprime-Cam to carry out a deep sky survey from the University of Tokyo. It reported a Sigma Eight (S8) value of 0.747, which matches earlier results from gravitational lensing studies. Sigma Eight (S8) is a key measure in cosmology that shows how matter is clustered or “clumpy” across the universe on a scale of 26 million light-years. It tells scientists how much visible and dark matter is gathered in different parts of space. This finding helps us understand how the universe evolved from a smooth early state after the Big Bang.

Notes:
The American Association of Petroleum Geologists and the United States Geological Survey (USGS) have recently launched formal hydrogen exploration initiatives. Hydrogen is seen as the fuel of the future due to its ability to help decarbonize the global economy and reduce greenhouse gas emissions. Natural hydrogen, or white hydrogen, is hydrogen that naturally occurs in the Earth’s crust, unlike industrially produced hydrogen. It forms through geological processes such as serpentinisation, where water reacts with iron-rich rocks, radiolysis, the breakdown of water by radioactive rocks, and the decomposition of organic matter in deep geological formations.

Notes:
NITI Aayog, along with the Institute for Competitiveness (IFC), released a report titled ‘Enhancing Micro, Small and Medium Enterprises (MSMEs) Competitiveness in India’. The report highlights reforms needed in credit access, skill development, innovation, and market linkages to boost MSMEs. Using firm-level data and Periodic Labour Force Survey (PLFS), it suggests ways to integrate MSMEs into global value chains. Focus sectors include textiles, chemicals, automotive, and food processing. Credit access improved between 2020 and 2024, yet only 19% demand was met formally by 2021, with ₹80 lakh crore unmet. The Credit Guarantee Fund Trust for Micro and Small Enterprises (CGTMSE) expanded but still needs redesign for wider impact.

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:
A recent report by the Wildlife Justice Commission (WJC) says global trafficking of pangolin scales has dropped sharply since 2020 due to COVID-19 disruptions, strong law enforcement, and changing smuggling methods. Pangolins are insect-eating mammals found in tropical forests, grasslands, and farms, often near people. There are 8 species of pangolins — 4 in Africa and 4 in Asia, including the Indian pangolin found in India, Nepal, Sri Lanka, and Bangladesh. They eat ants and termites, helping control pests and improve soil, which supports healthy ecosystems. Pangolins are hunted for their meat and scales used in traditional medicine. The Indian pangolin is listed as Endangered and the Chinese pangolin as Critically Endangered on the International Union for Conservation of Nature (IUCN) Red List.

Notes:
Recently, scientists observed repeated unrest at Campi Flegrei between 1982–1984 and 2011–2024, involving land uplift, earthquakes, and underground rumbling due to rising fluid pressure. Campi Flegrei, also called the Phlegraean Fields, is an active volcanic system located near Naples, Italy. Unlike single-cone volcanoes like Mount Vesuvius, Campi Flegrei is a large caldera, which is a sunken volcanic area formed after a huge eruption. The caldera spans about 12 to 15 kilometers and was formed by a massive eruption nearly 39,000 years ago. That eruption may have triggered climate changes that contributed to the decline of Neanderthals.

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.

Notes:
The Maharashtra government launched the “One State, One Registration” scheme to make property registration easy and citizen-friendly. It allows people to register property documents at any sub-registrar office in Maharashtra, regardless of where the property is located. Earlier, buyers had to register documents only at the local sub-registrar office of the property, which caused delays and overcrowding. The new policy saves time, reduces paperwork, and helps senior citizens and Non-Resident Indians (NRIs). Legal steps and documents like sale deed, Aadhaar, and PAN remain unchanged. It does not affect stamp duty or registration fees. The National Informatics Centre (NIC) is using technology like Geographic Information System (GIS), drone mapping, and blockchain for better accuracy. This move is expected to boost real estate activity and investor confidence in the state.
