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:
The Reserve Bank of India (RBI) has made it mandatory for all banks, financial institutions, and regulated entities to submit applications through the PRAVAAH portal from May 1, 2025. PRAVAAH stands for Platform for Regulatory Application, Validation, and Authorization. It is a secure, web-based digital portal launched by RBI on May 28, 2024. The portal serves as a single-window system for applying for RBI permissions, licenses, and approvals. This step aims to improve transparency, reduce paperwork, and speed up the approval process. It ensures faster communication between applicants and the RBI.

Notes:
Years of efforts by Jharkhand forest officials have succeeded with Jaigir becoming the first village to be fully relocated outside the core area of Palamu Tiger Reserve (PTR). Palamu Tiger Reserve is located in the western part of the Chotanagpur plateau and spreads across Latehar and Garhwa districts in Jharkhand. It covers a total area of 1,014 square kilometers, with 414 square kilometers as core and 600 square kilometers as buffer. It was among the first nine reserves established under ‘Project Tiger’, a conservation program launched in 1973 by the Government of India.

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 Army and Air Force versions of the Advanced Light Helicopter (ALH) Dhruv have been cleared for flying again after a review by a Defect Investigation Committee. All 330 ALH helicopters were grounded after an ALH Mark-III of the Indian Coast Guard crashed during a training sortie in Porbandar, Gujarat in January 2025, killing three crew members. The helicopter was also absent from the Aero India 2025 event due to safety concerns. ALH Dhruv is a multi-role helicopter developed by Hindustan Aeronautics Limited (HAL) for transport, utility, reconnaissance, and medical evacuation.

Notes:
The Election Commission of India (ECI) will soon launch a new digital platform called ECINET to streamline electoral services. ECINET is a single-point user-friendly interface for voters, election officials, political parties, and civil society. It will integrate over 40 existing mobile and web apps of the ECI into one platform. Popular apps like Voter Helpline, Voter Turnout, cVIGIL, Suvidha 2.0, Electoral Search and Management System (ESMS), Saksham, and Know Your Candidate (KYC) will be merged into ECINET. It will offer a clean User Interface (UI) and smooth User Experience (UX), reducing the need to download multiple apps. ECINET will follow the Representation of the People Act 1950, 1951, and related rules and guidelines.

Notes:
A recent breakthrough came as an international team of scientists successfully mapped the genome of the Saola using tissue fragments from hunter-collected remains. The Saola, scientifically named Pseudoryx nghetinhensis, is one of the rarest land mammals and is nicknamed the “Asian Unicorn” because of its secretive nature. It was first discovered in 1992 during a joint survey by the Vietnamese Ministry of Forestry and the World Wide Fund for Nature (WWF). It is listed as Critically Endangered on the International Union for Conservation of Nature (IUCN) Red List, with only about 50 to 300 individuals estimated as of 2015. The Saola lives in the evergreen forests of the Annamite Mountains along the Vietnam–Laos border, a region rich in biodiversity and rainfall.

Notes:

The pilgrimage takes place during the Shravan month, when the lingam reaches its full size. The origin of the pilgrimage is mentioned in the Sanskrit text “Bringesha Samhita.”

Notes:
A new study reveals that Indonesia’s Anak Krakatau volcano, which collapsed in 2018 causing a deadly tsunami, showed warning signs years in advance. Anak Krakatau, meaning “Child of Krakatoa,” is located in the Sunda Strait between Java and Sumatra in Indonesia. It is a stratovolcano, formed by alternating layers of solidified lava and ash. The volcano sits at the convergent boundary between the Indo-Australian and Eurasian tectonic plates. Anak Krakatau is part of the Pacific Ring of Fire, a seismically active zone around the Pacific Ocean. In December 2018, its southwest flank collapsed, generating a tsunami that killed over 400 people and caused widespread destruction.
