Current Affairs Quiz - January, 2025

Notes:
LingoSat, a joint project of Japan’s Kyoto University and Sumitomo Forestry, is the first wooden satellite launched into orbit. It uses wood from honoki, a magnolia tree native to Japan, and is assembled using traditional Japanese crafts without screws or glue. The satellite’s name comes from the Latin word “Ligno,” meaning wood. LignoSat 1 is a CubeSat measuring 10 cm on each side and weighing 900 grams. LignoSat 2, a 2U CubeSat, is planned for launch in 2026.

Notes:
India’s indigenous surgical robotic system, SSI Mantra, conducted two successful robotic cardiac telesurgeries. The first procedure, Telerobotic-assisted Internal Mammary Artery Harvesting, was completed in 58 minutes with 35-40 milliseconds latency. SSI Mantra successfully performed a robotic beating heart Totally Endoscopic Coronary Artery Bypass (TECAB), one of the most complex cardiac surgeries. SSI Mantra is the only robotic system globally approved for telesurgery and tele-proctoring, revolutionizing rural healthcare access in India. It recently received approval from the Central Drugs Standard Control Organisation (CDSCO) under the Drugs & Cosmetics Act, 1940.

Notes:
Silver nanowire-based conductive ink technology was transferred to two startups at NIT Warangal. The startups are M/s Chematico Technologies Private Limited (incubated at IIT Ropar) and M/s Vasanthbala Functional Materials Pvt Ltd (incubated at NIT Warangal). The technology was developed under a project funded by the Ministry of Electronics and Information Technology (MeitY). It aims to reduce dependency on foreign countries and tap into the growing demand for advanced electronic materials. The ink is used in flexible electronics, wearable devices, solar panels, RFID tags, and more. The global market for this ink is expected to surpass 16.87B by 2032. India imports conductive ink worth 15,72,000 annually from countries like the US, China, and Taiwan.

Notes:
IIT Roorkee researchers developed a method to degrade plasticizers like diethyl hexyl phthalate (DEHP) using bacterial enzymes. DEHP is found in plastics and personal care products, posing health risks. Esterase enzyme from Sulfobacillus acidophilus breaks DEHP into mono-(2-ethylhexyl) phthalate (MEHP) and 2-ethyl hexanol. The enzyme was structurally studied using X-ray crystallography and remains active for about a month. Researchers used four additional enzymes from Comamonas testosteroni to complete the degradation process. Integrating enzymes into bacteria ensures prolonged activity and continuous degradation without needing fresh batches. Plasticizers enhance flexibility and shine in products but can be absorbed through the skin, posing health dangers.

Notes:
Larsen & Toubro launched the second multi-purpose vessel, INS Utkarsh, for the Indian Navy at Kattupalli Shipyard near Chennai. INS Utkarsh, meaning “Superior in Conduct,” is built by L&T Shipbuilding Limited. The vessel is 106m long, 18.6m wide, with a displacement over 3,750 tonnes, and a maximum speed of 15 knots. It will enhance maritime surveillance, patrolling, and disaster relief capabilities of the Navy. The launch follows the first MPV, INS Samarthak, within three months. This aligns with India’s Aatmanirbhar Bharat and Make in India initiatives, showcasing indigenous shipbuilding progress.

Notes:
Raksha Mantri congratulated DRDO on the successful Field Evaluation Trials of the Nag Mk 2 missile. The Nag Mk 2 is a third-generation, indigenously developed Anti-Tank Fire-and-Forget Guided Missile. It is developed by Defence Research and Development Organisation (DRDO). It features fire-and-forget technology for precision targeting with minimal operator intervention. The missile can neutralize modern armored vehicles with explosive reactive armor (ERA). The Nag Missile Carrier version-2 was also field evaluated, and the weapon system is now ready for induction into the Indian Army.

Notes:
India ranks second after the US in the QS World Future Skills Index 2025 for job market preparedness in AI, digital, and green sectors. India scores highly in the “Future of Work” indicator, trailing the US by less than a point. The country excels in readiness for digital roles alongside Mexico. However, India faces challenges in its higher education system, industry collaboration, and equipping graduates with in-demand skills. Despite strong GDP growth and a youthful population, India lags in sustainability and innovation metrics. To unlock potential, India needs better integration between education and industry.

Notes:
China launched Pakistan’s first indigenous Electro-Optical (EO-1) satellite, PRSC-EO1. The launch occurred from the Jiuquan Satellite Launch Center using a Long March-2D carrier rocket. The satellite is equipped with electro-optical sensors for collecting Earth observation data.

Notes:
Kalaripayattu, a traditional martial art from Kerala, is included only as a demonstration event in the 38th National Games in Uttarakhand. According to mythology, the warrior sage Parasurama introduced Kalaripayattu. The term Kalaripayattu combines “kalari,” meaning a place of combat, and “payattu,” meaning fighting in Malayalam. Uttarakhand will host the National Games 2025 from January 28 to February 14, 2025.
