Current Affairs Quiz - February, 2024

Notes:
Union Minister of Environment, Forest, and Climate Change, Shri Bhupender Yadav released India’s first-ever Snow Leopard Population Assessment report. The four-year-long scientific exercise, coordinated by the Wildlife Institute of India, estimates approximately 718 snow leopards in the wild. Ladakh leads with 477, followed by Uttarakhand (124), Himachal Pradesh (51), Arunachal Pradesh (36), Sikkim (21), and Jammu and Kashmir (nine). India holds 10-15% of the global snow leopard population.

Notes:
India has proposed the “Maratha Military Landscapes of India” for UNESCO World Heritage List recognition in 2024-25. Developed between the 17th and 19th centuries, these military landscapes showcase an exceptional fortification system envisioned by Maratha rulers. The network of forts, spanning the Sahyadri mountain ranges, Konkan Coast, Deccan Plateau, and Eastern Ghats, integrates distinctive landscapes. Notable components include Salher fort, Shivneri fort, Raigad, Vijaydurg, and others. The Maratha Military ideology, dating from the 17th century, continued until Peshwa rule in 1818 CE.

Notes:
The Secretary, Department of Telecommunications, Ministry of Communications, unveiled the “Bharat 5G Portal” during ‘Bharat Telecom 2024.’ This integrated platform focuses on quantum, 6G, IPR, and 5G domains, catering to startups, industry, and academia. In collaboration with PANIIT USA, it introduces the Future Tech-Experts registration portal to support India’s Telecom ecosystem. The portal serves as a centralized hub for quantum, IPR, PoCs/Pilot, 5G, and 6G, promoting innovation, collaboration, and knowledge-sharing in the telecom sector for Atmanirbhar Bharat.

Notes:
Operation Black Gold is about the seizure of an alloy containing 16.67 kg of gold and 39.73 kg of silver in Delhi. The alloy was worth over Rs 10 crore and was seized by the Directorate of Revenue Intelligence (DRI) at FPO Delhi. The Revenue Intelligence Directorate (DRI) acted on intelligence to seize seven shipments of “electrical current/potential meters”. The meters were declared as “current guior machines”. According to preliminary investigations, a systematic syndicate was involved in the gold smuggling. The gold was coated with silver to change its color from yellow to white. The white mixture was then used to make electric meter covers, which were then painted black to avoid suspicion.

Notes:
Researchers have discovered a new frog species, Sphaerotheca varshaabhu, thriving in Bengaluru’s urban landscape. Named for its rain-loving behavior, the amphibian emerges from burrows during early showers. With unique characteristics, it adapts to urban challenges, displaying behaviors and physical attributes that set it apart. The team employed genetic analysis, morphological studies, and bioacoustics to confirm its distinctiveness from known frog species.

Notes:
The Interim Budget prioritizes the advancement of ‘Blue Economy 2.0,’ concentrating on sustainable development concerning oceans, seas, and coasts. Key initiatives include schemes for coastal restoration, aquaculture, and mariculture, with an integrated approach. Plans encompass setting up five integrated aquaparks and enhancing the Pradhan Mantri Matsya Sampada Yojana for increased productivity, exports, and job creation. The Blue Economy is defined by the World Bank as the sustainable use of ocean resources for economic growth and improved livelihoods, preserving ocean ecosystem health.

Notes:
Astro Sat, India’s inaugural multi-wavelength astronomy mission, successfully measured the X-ray polarization of the Cygnus X-1 black hole system. Discovered four decades ago, Cygnus X-1 is among the first confirmed black hole systems in our galaxy. The black hole is 20 times the Sun’s mass, with a companion supergiant star (40 times more massive) in a binary system. Located 400 times farther than Earth-Sun distance, the gravitational pull forms an accretion disk, generating soft X-rays.

Notes:
Banaras Hindu University (BHU) inaugurates North India’s first human DNA bank, equipped with an Automated DNA Extractor Machine developed indigenously under the ‘Make in India’ initiative. Installed at the Gnyaneshwar Lab in the Zoology Department on January 30, 2024, the machine minimizes plastic usage, ensuring environmental sustainability. It efficiently extracts DNA from various biological materials, accommodating 32 samples in 30 minutes. The initiative stemmed from a three-day conference on Personalized Medicine held in March 2023, where BHU expressed readiness to establish a genome bank inspired by Estonia.

Notes:
Researchers discovered a new fungus species, Trichoglossum syamviswanathii, in Kerala. Trichoglossum is a genus of fungus known as “hairy earth tongues” due to its filamentous structure. The fungus, with 55 identified genera and 21 recognized species globally, exhibits saprotrophic behavior and can be found in plant roots as endophytes. Predominantly distributed in tropical and temperate forests across five continents, these fungi play a crucial role in decomposing organic matter.

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.
