Notes:
New maps reveal a hidden hydrothermal system under Lake Rotorua, at a dormant volcano’s heart in New Zealand. Hydrothermal systems, common near convergent plate boundaries and mid-ocean ridges, need fluids, heat, and permeability. Seawater percolates through oceanic crust, heating to 350-400°C, producing chemically modified hydrothermal fluid. Ejected to the seafloor, it forms chimney-like deposits, supporting deep-sea chemosynthetic communities. This discovery highlights the dynamic geological processes beneath the lake, providing insights into hydrothermal systems’ intricate workings.

Notes:
The GRAPES-3 experiment, situated in Ooty, India and operated by the Tata Institute of Fundamental Research, made a significant discovery in the cosmic-ray proton spectrum, revealing a new feature at 166 TeV. Equipped with air shower detectors and a large muon detector, GRAPES-3 aims to investigate the origin, acceleration, and propagation of cosmic rays, including the existence of the “Knee” in their energy spectrum. It also explores the production of highest-energy cosmic rays, astronomy of multi-TeV γ-rays, and the impact of the Sun on Earth.

Notes:
Uttarakhand’s Cabinet, under Chief Minister Pushkar Singh Dhami, has approved the Uniform Civil Code (UCC) bill—a historic decision. Based on committee recommendations, the bill aims to standardize civil laws, transcending religious affiliations. The proposed measures include banning polygamy and child marriage, establishing a common marriageable age, and enforcing uniform grounds and procedures for divorce, promoting legal standardization.

Notes:
The formal launch of India’s Unified Payment Interface (UPI) occurred during Republic Day celebrations in Paris, with French President Emmanuel Macron present. The Indian Embassy introduced UPI at the Eiffel Tower, marking its global expansion. Developed by the National Payments Corporation of India in 2016, UPI consolidates multiple bank accounts into a single mobile application, offering a convenient system for managing diverse accounts on one platform.

Notes:
Exercise Vayu Shakti-24 will be held on February 17, 2024 at the Pokhran Air to Ground Range, near Jaisalmer, Rajasthan. The exercise will demonstrate the Indian Air Force’s offensive and defensive capabilities. The exercise will involve over 100 aircraft, including fighter jets, transport aircraft, helicopters, mid-air refuellers, airborne warning and control system (AWACS) aircraft, and unmanned systems. The fighter planes will target and destroy simulated enemy sites with missiles, precision-guided munitions, bombs, and rockets.
