Science & Technology Current Affairs MCQs

Notes:
AnemiaPhone, developed by Cornell University, is now part of Indian Council of Medical Research (ICMR) programs for anemia, women’s health, and maternal and child health in India. It offers quick, accurate, and low-cost iron deficiency assessment. Anemia affects 50% to 70% of pregnant women in India, with iron deficiency as the main cause. The device uses a drop of blood on a test strip, similar to a COVID-19 test, providing results in minutes. Data is uploaded to a clinical database via mobile devices, enabling healthcare workers to provide immediate guidance, referrals, or interventions.

Notes:
Researchers discovered two rare Neuroptera species, Indophanes barbara and Glenochrysa zeylanica, in Kerala. Indophanes barbara, an antlion from the Myrmeleontidae family, does not build pits like other antlion larvae and lives in loose soil for protection. Adult Indophanes barbara resemble damselflies but can be identified by their long antennae and belong to holometabolous Neuroptera insects, unlike hemimetabolous damselflies. Glenochrysa zeylanica, a green lacewing from the Chrysopidae family, was rediscovered in Wayanad after 111 years and reported for the first time in India. Neuroptera, commonly called lacewings, are terrestrial insects with complex wing vein patterns.

Notes:
Hindustan Aeronautics Limited (HAL) conducted the engine ground run of the Combat Air Teaming System (CATS) Warrior on January 11, 2025, ahead of Aero India 2025. Combat Air Teaming System (CATS) is an Indian unmanned and manned combat aircraft teaming system. Hindustan Aeronautics Limited (HAL) developed this system. The system enhances surveillance, strike capabilities, and reduces human error.

Notes:
New research reveals that genetic mutations in Huntington’s Disease (HD) can have delayed effects, impacting disease progression over time. Huntington’s Disease (HD) is a genetic condition causing gradual loss of brain cell function, leading to their death. It affects brain regions regulating voluntary movement, memory, and decision-making, primarily the basal ganglia and brain cortex. HD is caused by a mutation in the HTT gene, which produces huntingtin protein crucial for neuron function. Mutated huntingtin proteins have abnormal shapes, damaging and killing neurons. HD is inherited; each child of an affected parent has a 50% chance of developing the disease. It affects 3 to 7 out of 100,000 people, primarily of European ancestry.

Notes:
IIT-Madras has launched a zero-waste bioplastics initiative supported by the Ministry of Chemicals and Fertilisers. The initiative aims to develop biodegradable, microplastic-free, and cost-effective alternatives to conventional plastics. Third-generation bioplastics use agricultural residues, algae, and waste materials, avoiding food security concerns linked to earlier food-based bioplastics. These bioplastics fully decompose, leaving no harmful particles behind, reducing the environmental footprint. The centre is also exploring bioplastics for food packaging and medical textiles, including biodegradable implants from agricultural waste.

Notes:
South Africa’s MeerKAT telescope discovered a new giant radio galaxy (GRG) named ‘Inkathazo,’ meaning ‘trouble’ in Xhosa and Zulu. The galaxy spans 3.3 million light-years, 32 times the size of the Milky Way, and is 1.44 billion light-years from Earth. GRGs are massive structures that emit jets of hot plasma powered by supermassive black holes. These jets glow at radio frequencies and stretch millions of light-years into space. Once considered rare, GRGs are now being discovered frequently due to advanced radio telescopes like MeerKAT in South Africa’s Northern Cape.

Notes:
Russia is reportedly starting large-scale production of Iskander-M tactical ballistic missiles. The Iskander (SS-26 Stone) is a road-mobile short-range ballistic missile system, first used in 2008 against Georgia. It is developed by Russia. It is designed for tactical strikes on small, high-value land targets. The missile is 7.3 meters long, weighs 3,750 kg, and has a 500 km range with a payload of 480-700 kg. It can carry conventional or nuclear warheads, travel at Mach 7, and reach over 30 miles in altitude. Equipped with decoys, maneuverable reentry, and self-targeting to bypass defense systems.

Notes:
Satya Nadella discussed Jevons Paradox, noting AI efficiency may increase demand and make it a commodity. Jevons Paradox states that technological progress making a resource cheaper often leads to higher demand rather than reduced use. It was proposed by William Stanley Jevons in 1865. Jevons observed that technology improving coal efficiency led to more coal being used, not less. Technological progress satisfies needs that couldn’t be met before due to lack of technology.

Notes:
Microsoft unveiled Majorana 1, its first quantum computing chip, to improve stability, speed, and practicality in quantum computing. The chip utilizes Majorana particles, an exotic quantum state, to minimize computational errors and enhance reliability. It is developed by Microsoft, with validation from Defense Advanced Research Projects Agency (DARPA), U.S.

Notes:
Microsoft CEO Satya Nadella showcased Project Farm Vibes in Baramati, Maharashtra, demonstrating AI-driven solutions that improved crop yields by 40% and reduced fertilizer use by 25%. The Agricultural Development Trust, Baramati, in collaboration with Microsoft, is expanding the project from 1,000 to 50,000 farmers. Project Farm Vibes is an AI-driven agricultural technology suite developed by Microsoft Research to improve farming efficiency, sustainability, and productivity. The project involves partnerships with Microsoft Research, Azure AI Team, and Oxford University AI researchers.
