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:
Less than 1% of doctors in India have registered with the National Medical Register (NMR) eight months after its launch. National Medical Register (NMR) is a centralized digital database that includes all licensed allopathic (MBBS) doctors in India. It was launched in August 2024 under Section 31 of the National Medical Commission (NMC) Act, 2019. The Ministry of Health and Family Welfare, Government of India, is the nodal ministry for the NMR. The NMR aims to create a comprehensive registry of all allopathic doctors in India, ensuring transparency and accountability in the medical field. It also enhances public trust, helps in credential verification, and aids in policy planning for healthcare.

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:
Every year on May 3, World Press Freedom Day is celebrated to highlight the vital role of the media, known as the fourth pillar of democracy. The day spreads awareness about the struggles faced by journalists and supports the free flow of information. It honours media professionals who have risked or lost their lives in search of truth. This year’s theme is ‘Reporting In The Brave New World – The Impact Of Artificial Intelligence On Press Freedom And The Media.’ The day was established by the United Nations General Assembly (UNGA) in 1993 after a 1991 recommendation by UNESCO.

Notes:
The Indian Council of Agricultural Research (ICAR) has recently developed two genome-edited rice varieties, marking a major advancement in Indian agricultural science. ICAR is an autonomous body under the Department of Agricultural Research and Education (DARE), Ministry of Agriculture and Farmers Welfare, Government of India. It was founded on 16 July 1929, initially as the Imperial Council of Agricultural Research, following recommendations from the Royal Commission on Agriculture. ICAR’s headquarters is in New Delhi, and it coordinates research in agriculture, horticulture, fisheries, and animal sciences across India.

Notes:
A new mosquito species called the “Pwani molecular form” has been found in coastal areas of Tanzania and Kenya, drawing global attention to malaria control. It belongs to the Anopheles gambiae complex, which includes some of the world’s most dangerous malaria-spreading mosquitoes. This mosquito shows strong genetic differences from other species in the same group, suggesting unique behaviour or environmental adaptation. Genetic studies confirm it is only found along the coastal regions of East Africa, mainly in Tanzania and Kenya. It does not carry the usual genes for insecticide resistance found in other malaria vectors. This may mean it has a different resistance method or is more sensitive to current insecticides.

Notes:
India recently halted the flow of water through the Baglihar Dam on the Chenab River, a significant move impacting water access to Pakistan. The Baglihar Dam, also known as the Baglihar Hydroelectric Power Project, is located on the Chenab River in the Doda District of Jammu and Kashmir. It features a concrete gravity dam that is 144.5 meters high and 363 meters long, with a reservoir capacity of 475 million cubic meters. The underground powerhouse of the project measures 221 meters long, 24 meters wide, and 51 meters high.

Notes:
India has become the first country in the world to develop genome-edited rice varieties. The Indian Council of Agricultural Research (ICAR) has developed two such varieties named DRR Rice 100 (Kamla) and Pusa DST Rice. These rice varieties were developed using genome editing technology based on Clustered Regularly Interspaced Short Palindromic Repeats-CRISPR Associated Protein (CRISPR-Cas). This technology allows precise changes in the genetic material without adding any foreign DNA. Genome editing targeted the Site Directed Nuclease 1 (SDN1) and SDN2 types of genes, which are approved under India’s biosafety rules. The development was supported by the National Agricultural Science Fund (NASF), which funds strategic agricultural research.

Notes:
Defence Research and Development Organisation (DRDO) has successfully conducted the first flight trial of the Stratospheric Airship Platform in Sheopur, Madhya Pradesh. The platform was developed by DRDO’s Aerial Delivery Research and Development Establishment (ADRDE) based in Agra. The airship carried an instrumental payload and reached a high altitude of about 17 kilometres. The total flight lasted 62 minutes and helped gather important data through onboard sensors. This data will help in building accurate simulation models for future high-altitude missions. The test also checked the envelope pressure control and emergency deflation systems, and the airship was safely recovered.
