Science & Technology Current Affairs MCQs

Notes:
Recently, the Minister of State for Communications and Rural Development launched the high-capacity SAKSHAM-3000 to boost self-reliance and global competitiveness. SAKSHAM-3000 is a compact 25.6 Terabits per second (Tbps) switch-router developed by Centre for Development of Telematics (C-DOT). It is built for modern data centres, large enterprises, telecom operators, and hyperscale data centres. It has ultra-low latency, wire-speed processing, and uses the modular C-DOT Router Operating System (CROS).

Notes:
Recently, the World Health Organization (WHO) launched the “3 by 35” Initiative to tackle non-communicable diseases (NCDs). It urges countries to raise taxes on tobacco, alcohol, and sugary drinks to achieve at least a 50% real price increase by 2035. NCDs like heart disease, cancer, and diabetes cause over 75% of global deaths. Higher taxes could prevent 50 million premature deaths over 50 years and generate USD 1 trillion in public revenue in the next decade. Between 2012 and 2022, around 140 countries already raised tobacco taxes, showing large-scale change is achievable.

Notes:
The Indian Institute of Science (IISc), Bengaluru, recently launched the BHARAT study under its Longevity India Program. BHARAT stands for Biomarkers of Healthy Aging, Resilience, Adversity, and Transitions. The study aims to map physiological, molecular, and environmental indicators that drive ageing in Indians. It will build India’s first comprehensive ageing database. It includes multiparametric analysis, advanced clinical assessment, and lifestyle factors. It will identify biomarkers for healthy ageing and set the Bharat Baseline for normal health values in India.

Notes:
Recently, Bengaluru-based space company Protoplanet launched the Human Outer Planetary Exploration (HOPE) station in Ladakh’s Tso Kar region. HOPE is a moon and Mars simulation research station mimicking off-Earth terrain and environment. It is located in the high-altitude cold desert of Tso Kar basin, Ladakh. The project is developed by Protoplanet with technical and financial support from Indian Space Research Organisation (ISRO). It aims to study human psychological, physiological, and epigenetic responses in extreme isolation. It supports India’s long-term space goals including a crewed lunar mission by 2040 and a space station by 2035.

Notes:
Indian space-tech startup Dhruva Space is set to launch its first commercial satellite mission named LEAP-1. LEAP-1 will carry payloads for Artificial Intelligence (AI) and Earth observation. It uses the indigenously developed P-30 satellite platform, which was space-qualified on ISRO’s PSLV-C58 in January 2024 during the LEAP-TD mission. The mission is jointly developed by Dhruva Space, Akula Tech (Australia), and Esper Satellites (Australia).

Notes:
Pfizer recently launched its 20-valent pneumococcal conjugate vaccine (PCV20) for adults in India. PCV20 protects against 20 serotypes causing most pneumococcal diseases. Pneumococcal disease is caused by the bacterium Streptococcus pneumoniae. It can cause mild infections like ear infections and severe ones like pneumonia, meningitis, and bloodstream infections. Around 90 serotypes exist globally; few cause most diseases. It is a major global health issue, especially affecting young children and the elderly in developing countries.

Notes:
Researchers have identified Ideonella sakaiensis, a bacterium that can degrade polyethylene terephthalate (PET) plastic. It belongs to the genus Ideonella and family Comamonadaceae. It uses polyethylene terephthalate (PET) as both a carbon and energy source, breaking it into harmless building blocks. These by-products can be consumed by I. sakaiensis and other organisms. It is discovered by researchers in Japan from PET-contaminated soil. It is Gram-negative, rod-shaped, motile, non-sporing, non-pigment-producing, and monotrichous.

Notes:
Indian Oil Corporation Ltd. (Indian Oil) became the first company in India to secure International Sustainability & Carbon Certification (ISCC) CORSIA for Sustainable Aviation Fuel (SAF) at its Panipat Refinery. The certification is mandatory for commercial SAF production and aligns India with global aviation fuel standards. Certificate was handed over by Cotecna to Indian Oil Chairman A.S. Sahney in New Delhi. ISCC CORSIA, developed under Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) of International Civil Aviation Organization (ICAO), ensures sustainability and lifecycle carbon standards.

Notes:
Arunachal Pradesh Education Minister Pasang Dorjee Sona inaugurated a state-of-the-art space laboratory at Mechuka in Shi-Yomi district. The lab is named Pasang Wangchuk Sona ISRO Space Laboratory in honour of his late father. It was set up at Mechuka Government Higher Secondary School in collaboration with Indian Space Research Organisation (ISRO) and Muskaan Foundation. The lab will provide students hands-on experience in space science and technology. It aims to foster curiosity, innovation, and scientific thinking among youth.

Notes:
The World Health Organization (WHO) recently announced that Nepal has eliminated rubella as a public health problem. Rubella, also called German measles or three-day measles, is a contagious viral infection known for its red rash. It is caused by the Rubella virus, a single-stranded RNA virus, different from the measles virus. Rubella spreads through coughing, sneezing, contaminated surfaces, and from mother to fetus during pregnancy. This can lead to fetal death or Congenital Rubella Syndrome (CRS), causing hearing loss, eye and heart defects, autism, diabetes mellitus, and thyroid problems.
