Notes:
The Gangasagar Mela organizers introduced initiatives like certificates for pilgrims, e-Anushandhan for facilities access, and e-Parichay QR code identity bands. The Gangasagar Mela is an annual Hindu festival held on Sagar Island, West Bengal, at the confluence of the Ganges and the Bay of Bengal. It includes rituals like the sacred bath and Deepdan and is celebrated during Makar Sankranti, marking the Sun’s transition into Capricorn.

Notes:
A flagship river-link irrigation project in Rajasthan will submerge 37 sq. km of Ranthambhore Tiger Reserve (RTR), dividing it into two sections. It is situated at the junction of the Aravallis and Vindhyas ranges in Rajasthan. It was once a royal hunting ground for Jaipur’s Maharajas and is now one of northern India’s largest tiger reserves. The reserve is ideal for tiger monitoring due to its unique climate and vegetation. It is bordered by the Chambal River in the south and the Banas River in the north. The Ranthambhore Fort, a UNESCO World Heritage Site, lies within the reserve.

Notes:
Google-backed Pixxel launched India’s first private satellite constellation, marking a milestone for the country’s private space sector. The satellites use hyperspectral imaging technology to capture detailed data across light bands for agriculture, mining, environmental monitoring, and defense. This technology can help improve crop yields, track resources, monitor oil spills, and provide better details than existing technology. Three more satellites are expected to be deployed by mid-2025. The global satellite imagery market is projected to reach $19 billion by 2029.

Notes:
Centre for Development of Telematics (C-DOT) and IIT Delhi signed an agreement to develop THz communication front ends for 6G under the Telecom Technology Development Fund (TTDF). TTDF is established under the Universal Services Obligation Fund (USOF), now called Digital Bharat Nidhi, by the Department of Telecom. The fund supports research, design, prototyping, testing, and manufacturing in telecommunications. It aims to foster rural-specific communication technologies, promote technology ownership, and encourage indigenous manufacturing. TTDF seeks to boost exports, reduce imports, enhance co-innovation, and support Intellectual Property creation in the telecom sector.

Notes:
India has developed the world’s most powerful hydrogen train engine with 1,200 horsepower. It was made by Indian Railways using indigenous technology. The first trial run will be conducted on the Jind-Sonipat route in Haryana. This innovation supports hydrogen-powered trains and can be adapted for trucks, tugboats, and other vehicles.

Notes:
The Musi River Historic Buildings in Hyderabad and Bhuj Historic Water Systems in Gujarat are listed in the 2025 World Monuments Watch by the New York-based World Monuments Fund (WMF). These sites face risks from climate change and water crises, highlighting the need for advocacy and preservation. WMF emphasizes heritage as a pathway for rejuvenation, sustainability, and resilience amid Hyderabad’s environmental challenges and rapid change.

Notes:
New research reveals that genetic mutations in Huntington’s Disease (HD) can have delayed effects, impacting disease progression over time. Huntington’s Disease (HD) is a genetic condition causing gradual loss of brain cell function, leading to their death. It affects brain regions regulating voluntary movement, memory, and decision-making, primarily the basal ganglia and brain cortex. HD is caused by a mutation in the HTT gene, which produces huntingtin protein crucial for neuron function. Mutated huntingtin proteins have abnormal shapes, damaging and killing neurons. HD is inherited; each child of an affected parent has a 50% chance of developing the disease. It affects 3 to 7 out of 100,000 people, primarily of European ancestry.

Notes:
India becomes the fourth country to successfully achieve Space Docking Experiment (SpaDeX), after the US, Russia, and China. The technology allows two satellites to dock in space, enabling the assembly of larger modules and overcoming rocket payload limits. This technology is crucial for long-duration missions, Mars exploration, lunar sample return, and the planned Bharatiya Antariksh Station for resupply and crewed missions.

Notes:
Satellite images show a nearly completed airstrip on Yemen’s Abd al-Kuri Island, likely built by the UAE. Abd al-Kuri Island is 65 miles southwest of Socotra, in the Indian Ocean, part of the Socotra Archipelago. Although it belongs to Yemen, the island is geographically closer to Somalia, about 110 km northeast of Cape Gwardafuy. The island is rocky, 35 km long, and 5 km wide, with its highest point at 700 meters, Mount Jebel Saleh. With fewer than 500 residents, its inhabitants mainly rely on fishing, and settlements are connected by dirt roads. The island features the endemic Euphorbia abdalkuri plant.

Notes:
The Forest Department is urging residents of Sheribikanahalli Tanda, in the Chincholi Wildlife Sanctuary, to relocate due to the area’s ecological sensitivity. Chincholi Wildlife Sanctuary is located in Kalburgi District, North Karnataka, and spans 134.88 sq.km. It was declared a sanctuary in 2011. It is the first dry land wildlife sanctuary in South India and is also referred to as the Ooty of Telangana. The sanctuary is home to the Chandrampalli dam and four smaller dams. It also shelters the Lambani Tandas, a protected tribal community living in the forest.
