Science & Technology Current Affairs MCQs

Notes:
A Union Minister highlighted the potential of combining India’s ancient wisdom with modern science at the SHRI Programme’s 5th anniversary. The SHRI Programme brings together experts from various fields to capture data, form collaborations, and offer technology solutions for cultural heritage issues. Key initiatives include non-invasive preservation techniques, digitalizing the Ajanta caves, and artifact restoration. The programme is supported by the Ministry of Science & Technology to promote cultural heritage preservation through innovative technologies.

Notes:
Rwanda has declared its first-ever Marburg Virus Disease (MVD) outbreak over, with 42 days without new cases, confirmed by WHO. MVD is a severe, often fatal hemorrhagic fever caused by the Marburg virus, with no approved vaccines or treatments. First identified in 1967 in Marburg, Germany, linked to infected green monkeys. Outbreaks are mainly in sub-Saharan Africa, including Tanzania, Uganda, Angola, Ghana, Kenya, and Zimbabwe. The virus is transmitted from fruit bats to humans, spreading through direct contact with infected bodily fluids or contaminated surfaces.

Notes:
Researchers developed FELUDA, a low-cost diagnostic tool for detecting H. pylori and its mutations in dyspeptic patients in rural India with limited lab access. H. pylori is a common bacterium in the digestive tract, infecting over 43% of the world’s population and causing peptic ulcers, gastritis, dyspepsia, and gastric cancer. It survives in the stomach by reducing acidity and penetrating the lining, evading immune cells. Symptoms include stomach pain, nausea, loss of appetite, and weight loss. Treatment involves a 14-day triple therapy using antibiotics and a proton-pump inhibitor to reduce stomach acid.

Notes:
The Federal Aviation Administration (FAA) granted Blue Origin a commercial space launch license for the New Glenn rocket. The New Glenn rocket was developed by Blue Origin, an American space technology company. New Glenn is a heavy-lift, two-stage rocket named after John Glenn, the first American to orbit Earth. It stands 320 feet tall and has a 7-meter-wide payload fairing. The first stage is reusable, powered by seven BE-4 engines, producing over 3.8 million pounds of thrust. The second stage uses two BE-3U engines, powered by liquid hydrogen and oxygen, generating over 320,000 pounds of vacuum thrust.

Notes:
Researchers developed the first nanobody-based inhibitors targeting the Ebola virus. Ebola is caused by ortho ebola viruses, discovered in 1976 in the Congo, primarily found in sub-Saharan Africa. The virus gets its name from the Ebola River in Congo. Fruit bats are natural hosts, and it spreads through contact with infected animals or humans. Symptoms include fever, diarrhea, vomiting, bleeding, and often death. The average fatality rate is around 50%. There is no cure exists for Ebola. Experimental treatments like monoclonal antibodies have been used. Treatment focuses on fluid balance, blood plasma, and early intervention for better recovery chances.

Notes:
Centre for Development of Telematics (C-DOT) and IIT Delhi signed an agreement to develop THz communication front ends for 6G under the Telecom Technology Development Fund (TTDF). TTDF is established under the Universal Services Obligation Fund (USOF), now called Digital Bharat Nidhi, by the Department of Telecom. The fund supports research, design, prototyping, testing, and manufacturing in telecommunications. It aims to foster rural-specific communication technologies, promote technology ownership, and encourage indigenous manufacturing. TTDF seeks to boost exports, reduce imports, enhance co-innovation, and support Intellectual Property creation in the telecom sector.

Notes:
Taiwan will deploy advanced National Advanced Surface-to-Air Missile Systems (NASAMS) in North Taiwan to protect Taipei. NASAMS is a medium-range, ground-based air defense system developed by Raytheon (USA) and Kongsberg Defence & Aerospace (Norway). The system defends against aircraft, helicopters, cruise missiles, UAVs, and air-to-surface threats. It protects high-value assets and population centers and has been part of the US capital’s air defense since 2005. NASAMS is the first networked short- and medium-range system, integrating with other defense equipment.

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 Pralay missile, India’s first tactical quasi-ballistic missile, will be showcased in the Republic Day parade. It is a short-range surface-to-surface ballistic missile with a range of 150-500 km, developed to meet the Army’s tactical needs. Pralay can carry a 350-700 kg conventional warhead and strike enemy positions with high accuracy. It was developed by DRDO.

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.
