Science & Technology Current Affairs MCQs

Notes:
IIT-Madras researchers have extracted silicon carbide (SiC) from simulated moon soil, aiding future lunar habitat construction. Silicon carbide (SiC), also called carborundum, is a synthetic crystalline compound of silicon and carbon. It is extremely hard, has high thermal conductivity, and offers excellent resistance to wear, oxidation, and chemical reactions.

Notes:
Niger has become the first African country to eliminate onchocerciasis, or river blindness. It joins Colombia, Ecuador, Mexico, and Guatemala as WHO-verified onchocerciasis-free nations. Onchocerciasis is a parasitic disease affecting the eyes and skin, causing severe disability. It leads to disfiguring skin conditions, vision loss, and permanent blindness in severe cases. The disease has severely impacted livelihoods for decades. Over 99% of cases still occur in 31 African countries.

Notes:
The US Navy successfully tested the High-Energy Laser with Integrated Optical Dazzler and Surveillance (HELIOS) laser weapon on the USS Preble in 2024. HELIOS, developed by Lockheed Martin, can destroy targets (Hard Kill) or disable electronics (Soft Kill). It generates over 60 kilowatts of energy, with upgrades reaching 120 kilowatts. The test zapped an aerial drone, confirming operational capability. Lasers offer a cheaper alternative to missiles, crucial in regions facing drone and missile threats. Challenges include power supply, weather conditions, and system integration. The Navy plans to expand laser weapons, aiming for cost-effective and efficient defense.

Notes:
Uganda and WHO launched a historic clinical trial for a vaccine against the Sudan species of Ebola virus. Ebola is a deadly disease caused by orthoebolaviruses (formerly ebolavirus). It was first discovered in 1976 in the Democratic Republic of the Congo. The virus mainly affects humans and primates like gorillas, monkeys, and chimpanzees. It is found primarily in sub-Saharan Africa and poses a major health threat.

Notes:
ISRO unveiled the latest version of Finite Element Analysis of Structures (FEAST) software at the 8th National Finite Element Developers’ Meeting at IIT-Hyderabad. More than 250 industry leaders, academicians, and researchers attended to promote indigenous structural analysis software. FEAST, developed by ISRO’s Vikram Sarabhai Space Centre (VSSC), analyzes structures under various loads in aerospace, automobile, civil, and mechanical fields.

Notes:
IIT Guwahati researchers have developed a water-repellent, conductive textile that converts electricity and sunlight into heat to keep wearers warm in extreme cold. It helps prevent blood clotting, breathing issues, and weak immunity caused by prolonged cold exposure. The textile is made by spraying ultra-thin silver nanowires onto cotton fabric, making it lightweight, flexible, and durable. A lotus leaf-inspired coating makes it waterproof, stain-resistant, and oxidation-proof, ensuring long-lasting performance. It maintains 40°C-60°C for 10+ hours using a battery or solar energy.

Notes:
Researchers found that bacterial cellulose can be used as a bandage to help plants heal and regenerate faster. It is a natural polymer produced by certain bacteria. It has unique properties that make it effective for plant wound care. Bacterial cellulose bandages offer a sustainable alternative to chemical treatments. This method supports healthier plant growth and eco-friendly farming. It enhances plant healing, leading to better crop yields and resilience. This breakthrough integrates biotechnology into agriculture, promoting sustainable farming and food security.

Notes:
Nvidia has unveiled a powerful AI system called Evo 2 for genetic research. Evo 2 is the largest publicly available AI model for genomic data. It was built using 2,000 Nvidia H100 processors on Amazon’s cloud with Arc Institute and Stanford University. It is trained on 9 trillion nucleotides from 128,000+ organisms, covering plants, animals, and bacteria.

Notes:
John McFall has become the first person with a physical disability to be medically certified for a long-duration mission to the International Space Station (ISS). The European Space Agency (ESA) approved his selection, marking a historic milestone in inclusive space exploration. McFall, a former Paralympian, lost his right leg at 19 in a motorcycle accident. He won bronze in the 100m sprint at the 2008 Beijing Paralympics.

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.
