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 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.

On May 2, 2025, Australian boatbuilder Incat launched the world’s largest electric-powered ship, named Hull 096. The ship is a 130-metre-long aluminium catamaran designed for South American ferry operator Buquebus. It can carry 2,100 passengers and up to 225 vehicles across the River Plate between Buenos Aires and Uruguay. Hull 096 is powered by over 250 tonnes of batteries with an Energy Storage System (ESS) providing more than 40 megawatt hours of capacity. It was initially planned to run on Liquefied Natural Gas (LNG) but was later converted to battery power. The launch highlights a major step towards reducing maritime carbon emissions, which account for about three percent of global greenhouse gas emissions. This comes after the International Maritime Organization (IMO) voted for a global carbon pricing system, with cleaner fuels required by 2028.

Notes:
Maharashtra has become the first Indian state to approve a dedicated and independent Shipbuilding, Ship Repair and Ship Recycling Policy. The goal is to make Maharashtra a leading hub for shipbuilding, ship repair, and ship recycling. The state targets an investment of ₹6,600 crore and 40,000 jobs by 2030. By 2047, the aim is to attract ₹18,000 crore in investments and create 3.3 lakh jobs. The policy supports research and development (R&D), modern technology, and skilled workforce. It aims to contribute one-third of India’s total shipbuilding output by 2030.

Notes:
Scientists from the University of Oxford have suggested a new way to monitor volcanic eruptions using a method called shear-wave splitting. Shear-wave splitting happens when seismic waves travel at different speeds depending on their direction, especially through rocks with tiny cracks. This technique was studied at Mount Ontake in Japan, which is an active stratovolcano located on Honshū Island, near Tokyo. Mount Ontake is Japan’s second-highest volcano and lies in the Pacific Ring of Fire.

Notes:
Archaeologists have recently discovered prehistoric tools from the Lower Paleolithic age at Mangar Bani, highlighting its ancient human presence. Mangar Bani is a sacred grove and Paleolithic site located in the Aravalli hills on the Delhi-Haryana border. It lies within the only primary forest in the Delhi National Capital Region (NCR), meaning the forest is largely untouched by human activities and contains native tree species. Evidence shows continuous human occupation from around 100,000 years before present (BP) to 1000 AD. The site also has rock shelters and ancient rock and cave paintings estimated to be 20,000 to 40,000 years old.

Notes:
Kozhikode city has recently been honoured with membership in the Global Network for Age-friendly Cities and Communities (GNAFCC) of the World Health Organization (WHO).

The aim is to connect cities, communities, and organizations to create supportive environments for ageing populations. It works to inspire change, share knowledge, and help cities find smart, practical solutions. This membership shows Kozhikode’s commitment to healthy ageing and inclusive urban development.

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.
