Science & Technology Current Affairs MCQs

Notes:
Germany recently faced its first foot-and-mouth disease (FMD) outbreak in nearly 40 years, affecting water buffalo near Berlin. Foot-and-Mouth Disease (FMD) is a highly contagious viral disease impacting livestock like cattle, swine, sheep, and goats but not horses, dogs, or cats. The disease severely affects livestock production and disrupts trade in animals and animal products. It circulates in 77% of global livestock, mainly in Africa, the Middle East, Asia, and parts of South America. FMD is not a human health risk and is transmitted through excretions, secretions, and aerosolized virus from infected animals.

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:
China launched the world’s largest Compressed Air Energy Storage (CAES) project, “Nengchu-1”. It has begun full operation in Yingcheng, Hubei Province, China. It marks a milestone in China’s energy storage technologies and is the largest CAES facility globally. CAES stores electrical energy as potential energy by compressing air into sealed spaces like underground mines or salt rock caverns. Energy is stored during off-peak hours and released to the grid during peak demand.

Notes:
Scientists are concerned about the potential for ‘zombie deer’ disease, or Chronic Wasting Disease (CWD), to affect humans. CWD is a fatal neurological disease that primarily affects deer, elk, moose, and reindeer. Caused by prions, misfolded proteins that damage the brain, leading to severe dysfunction and spongy tissue. It spreads through body fluids like saliva, feces, blood, and urine, and can remain infectious in the environment for years. Symptoms include weight loss, behavioral changes, and increased drinking and salivation. There is no cure or vaccine, and although there’s no confirmed human transmission, experts remain cautious.

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:
The Central Drugs Standard Control Organisation (CDSCO) has approved Qartemi, a second “living drug,” which is a Chimeric Antigen Receptor (CAR) T-cell therapy designed to treat blood cancer. “Living drugs” involve modifying a patient’s cells and reintroducing them into the body. CAR T-cell therapy is an innovative immunotherapy where T-cells are genetically engineered to target cancer cells. T-cells are extracted from the patient’s blood, modified in the lab by adding a gene for a man-made receptor (CAR), which helps T-cells recognize cancer cells. Modified CAR-T cells are then reintroduced to kill cancer cells.

Notes:
The U.S. military has relocated Typhon missile launchers within the Philippines to improve mobility and survivability amid tensions with China and Russia. Typhon, or the Mid-Range Capability (MRC), is a mobile, surface-to-surface missile system developed by Lockheed Martin, United States. It features a modular design and can fire multiple missile types, including the SM-6 (500 km range) and Tomahawk cruise missiles (2,500 km range). The SM-6 strikes air and surface targets, while the Tomahawk is effective for land-attack and anti-ship missions. A full Typhon system includes four launchers, a command post, and support vehicles on trailers.

Notes:
Chinese researchers developed a new voice-based method for early Alzheimer’s detection. The study was led by Prof. Li Hai at the Hefei Institutes of Physical Science, Chinese Academy of Sciences. Alzheimer’s disease is a brain condition that causes memory loss and cognitive decline. It affects thinking, learning, and organizing skills over time. It is the most common type of dementia, making up 60-80% of cases. The disease impacts brain regions responsible for thought, memory, and language.

Notes:
Indian researchers at the Indian Institute of Astrophysics (IIA), Bengaluru developed a new method to measure solar storms’ size and speed. The method improves predictions of Coronal Mass Ejections (CMEs), which can disrupt Earth’s communication systems and power grids. It measures CME radial size and expansion speed, crucial for understanding their impact on Earth’s magnetic field. The approach estimates instantaneous expansion speed using a single observation point, making it more efficient. The method was tested on a 2010 CME event and will be used with Aditya-L1 for better space weather forecasting.

Notes:
The Finance Minister announced a ₹20,000 crore ‘Nuclear Energy Mission’ to develop indigenous Small Modular Reactors (SMRs). SMRs are small nuclear reactors with a maximum output of 300 MWe, producing 7.2 million kWh per day. In comparison, large nuclear plants generate over 1,000 MWe and 24 million kWh per day. SMRs are small, modular, and reactor-based, generating low-carbon electricity. They have small footprints, lower capital costs, and can be factory-built. SMRs can be deployed in locations unsuitable for large nuclear plants. They support incremental power additions, energy hubs, industrial heating, district heating, and hydrogen production.
