Notes:
The Madhya Pradesh government has launched the Tejaswi programme to build entrepreneurial skills and confidence in students. A multilateral Memorandum of Understanding (MoU) was signed between the School Education Department, State Open School, and partners Udyam Learning Foundation and The Education Alliance. The programme aims to give students knowledge about self-employment and emerging industries. It will train students in vocational skills to help them become self-reliant and handle life challenges. This initiative supports the goals of the National Education Policy 2020, which promotes vocational learning and life skills in school education.

Notes:
A new project called SeaCURE has begun on the south coast of England to remove carbon dioxide from the sea. The SeaCURE project is an initiative of the United Kingdom (UK) government. The SeaCURE project is testing if taking carbon directly from seawater can be a low-cost and large-scale way to cut down carbon dioxide in the air. This method is different from usual carbon capture techniques that focus on emissions at their source or pull carbon dioxide from the air. SeaCURE targets the ocean, where carbon levels are up to 150 times higher than in the atmosphere.

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:
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 Ramman Festival, inscribed in the UNESCO Representative List of the Intangible Cultural Heritage of Humanity, is celebrated in Uttarakhand. It takes place annually in late April, after the harvest season, in the twin villages of Saloor-Dungra. The festival honours Bhumiyal Devta, the village’s tutelary deity, and holds deep religious significance. The celebration includes complex rituals such as the recitation of a version of the epic of Rama, songs, and masked dances. A key feature is the singing of Jagar, a musical performance that narrates local legends.

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:
In a major step toward digital transformation, Chhattisgarh Chief Minister laid the foundation for India’s first Artificial Intelligence-based Data Center Park in Raipur. The facility will start with a five megawatt capacity and aims to grow to 150 megawatts. A 2.7-hectare area is being developed as a Special Economic Zone (SEZ) focused on Artificial Intelligence (AI) services. The project will see an investment of Rs 2,000 crore as it expands. The center will support green, energy-efficient technologies for sustainable operations. It will serve sectors like AI, Financial Technology (FinTech), Health Technology (HealthTech), defense, and data analytics. The infrastructure will use Graphics Processing Unit (GPU)-based systems for real-time data processing, streaming, and analytics.

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.

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.
