Science & Technology Current Affairs MCQs

Notes:
The Philippines has launched Southeast Asia’s first Coral Larvae Cryobank, a major step to protect marine biodiversity. The cryobank is a scientific facility that freezes and stores coral larvae at ultra-low temperatures. It preserves the genetic material of corals for future reef restoration and scientific research. The facility acts like a “genetic seed vault” for corals to help safeguard biodiversity from climate change and coral bleaching. The project is part of the Coral Research and Development Accelerator Platform (CORDAP). Philippines, Taiwan, Indonesia, Malaysia, and Thailand are jointly participating in this regional conservation effort.

Notes:
Meta Platforms has chosen Mumbai and Visakhapatnam as landing sites for its undersea cable project named Waterworth. Undersea cables are fiber-optic cables laid on the ocean floor to transmit information globally. They form the backbone of the international internet. Around 90% of global data and 80% of world trade are carried through undersea cables. They also facilitate approximately $10 trillion of financial transactions annually. The project will strengthen India’s connectivity with global digital networks and support faster internet and data services.

Notes:
On October 13, 2025, TechBharat Research Foundation (TBRF) and Google Cloud India launched India’s first Artificial Intelligence (AI) Centre of Excellence (CoE) for Public Good in Visakhapatnam, Andhra Pradesh (AP). The initiative was supported by the Government of Andhra Pradesh, particularly its Department of Information Technology, Electronics & Communications (IT, E&C). A Memorandum of Understanding (MoU) was signed between the Government of Andhra Pradesh and TechBharat Research Foundation (TBRF) for setting up and operating the CoE. TBRF will lead the CoE as a hub for applied AI research and public service solutions. Google Cloud India will provide cloud infrastructure, Gemini AI models, tools, mentorship, and market support.

Notes:
Health officials in Florida have recently confirmed cases of Chronic Wasting Disease (CWD), also called “Zombie Deer Disease.” It is a fatal neurological disease that affects deer, elk, moose, and reindeer. It attacks the central nervous system (brain and spinal cord). It is caused by prions, which are infectious misfolded proteins that damage the brain. Prions spread through body fluids like saliva, blood, and urine and can stay in soil and plants for years. Infected animals show weight loss, drooling, and strange behavior. There is no cure or vaccine, and the disease is always fatal.No human cases have been confirmed yet, but experts stay alert.

Notes:
Google announced that its quantum processor Willow has achieved the first “verifiable” quantum advantage. Quantum advantage means a quantum computer can outperform a classical computer in practice. The announcement was accompanied by an open-access paper in Nature by the Google Quantum AI and Collaborators team. Willow ran a new algorithm, Quantum Echoes, 13,000 times faster than the best classical algorithm on a supercomputer. The experiment used a technique called out-of-time-order correlator (OTOC) to track how information scrambles in quantum systems. OTOC measures how quantum information spreads, is scrambled, and can be “unscrambled” using time-reversal. Willow’s processor precisely controlled quantum bits (qubits) in a chaotic quantum system for the experiment.

Notes:
Russia has successfully tested its new atomic-powered and nuclear-capable underwater drone named Poseidon. President Vladimir Putin announced the test, calling it a major success and saying it cannot be intercepted. The test took place just days after Russia also tested the Burevestnik nuclear-powered cruise missile. Both tests are seen as signals to the United States amid the ongoing Ukraine conflict. The Poseidon drone was tested using nuclear power for the first time. It reportedly surpasses all current systems in speed and depth. Its nuclear reactor is 100 times smaller than those on submarines. The drone’s nuclear warhead is said to be more powerful than the Sarmat Intercontinental Ballistic Missile (ICBM).

Notes:
Russia has launched its newest nuclear submarine ‘Khabarovsk’, built to carry the underwater nuclear drone ‘Doomsday Missile’ (Poseidon). Poseidon is an unmanned, nuclear-powered underwater drone capable of carrying a nuclear warhead. It can travel at extremely high speeds and operate at great ocean depths, making it hard to detect or intercept. The missile can travel intercontinental distances underwater and strike coastal targets. It serves as a strategic nuclear deterrent, designed for massive retaliatory destruction in case of a nuclear conflict.

Notes:
China has achieved the world’s first conversion of thorium into uranium fuel inside a Thorium Molten Salt Reactor (TMSR). It marks the first-ever experimental data on thorium operation from within a molten salt reactor. The 2 megawatt liquid-fuelled TMSR is currently the only operating reactor successfully using thorium fuel. A Molten Salt Reactor (MSR) is a fourth-generation nuclear reactor using molten salt as both coolant and fuel carrier instead of solid rods.

Notes:
Eli Lilly’s weight-loss drug Mounjaro became India’s top-selling drug by value in October 2025. It overtook GlaxoSmithKline’s (GSK) Augmentin, a widely used antibiotic. Mounjaro earned ₹1 billion ($11.38 million) in October, while Augmentin made ₹800 million. By volume, Augmentin sold 5,784 units, whereas Mounjaro sold only 85 units due to its high price. Mounjaro helps control blood sugar and slow digestion and belongs to the GLP-1 receptor agonist class used for obesity and diabetes. It was launched in India in March 2025 and has earned ₹3.33 billion till October. Mounjaro’s consumption was 10 times higher than rival Wegovy by Novo Nordisk, launched in June 2025. Eli Lilly sold 262,000 units, while Novo Nordisk sold 26,000 units in October.

Notes:
Recently, researchers found that male and female brains respond differently as Batten Disease progresses, opening new paths for treatment. Batten Disease is a rare genetic disorder affecting the brain and nervous system. It is congenital, progressive, and terminal, leading to steady decline in nervous system function. Symptoms include loss of vision and seizures, beginning in infancy, childhood, or rarely adulthood. Life expectancy varies from early childhood to the twenties depending on the form.
