Science & Technology Current Affairs MCQs

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:
India recently launched its first fully indigenous commercial Earth Observation (EO) satellite constellation. It is developed by a private consortium led by Pixxel Space under the Public Private Partnership (PPP) model. The satellites carry advanced sensors like Panchromatic, Multispectral, Hyperspectral, and Microwave Synthetic Aperture Radar (SAR). They will provide Analysis Ready Data (ARD) and Value-Added Services (VAS). This reduces India’s dependence on foreign satellite data and ensures national data sovereignty. It positions India as a global leader in geospatial intelligence

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.

Notes:
NASA has launched “Surya”, an artificial intelligence (AI) model to improve space weather forecasting. Surya was developed in collaboration with IBM and trained on over nine years of data from NASA’s Solar Dynamics Observatory (SDO). It analyses massive streams of solar activity to detect early signs of solar flares and coronal mass ejections (CMEs). Solar storms can disrupt satellites, communication systems, aviation, GPS navigation, and power grids on Earth. Surya generates visual forecasts up to two hours in advance with higher accuracy than traditional methods. The model is open-source to enable global researchers to improve space weather defense.

Notes:
Researchers at the Institute of Nano Science and Technology (INST), Mohali, are developing a nanotechnology-based tool for early detection of Parkinson’s Disease (PD). Parkinson’s Disease (PD) is a rapidly growing neurological disorder in India, often diagnosed after significant neurodegeneration. The team focused on α-synuclein, a protein that changes from harmless to toxic forms, damaging brain cells. They created gold nanoclusters (AuNCs), ultrasmall particles coated with amino acids to selectively bind normal or toxic protein forms. The tool enables early-stage detection, improving treatment, quality of life, and reducing healthcare costs.

Notes:
Israeli defense technology firm Elbit Systems recently launched its advanced JUPITER space camera aboard the National Advanced Optical System (NAOS) satellite. The satellite was launched from Vandenberg Space Force Base, California, on a SpaceX Falcon 9 rocket. JUPITER supports military operations, environmental monitoring, scientific research, and wide-span observation missions. It features a large aperture, lightweight design, high-resolution panchromatic channel for black-and-white imaging, and a Near Infrared (NIR) channel for vegetation, water, and material analysis. The camera can capture continuous long image strips covering large areas efficiently.

Notes:
European Space Agency (ESA) Solar Orbiter, a joint project with NASA, was launched in 2020 to study the Sun closely. It became the first spacecraft to image the Sun’s poles. A new study in Astronomy and Astrophysics traced the origin of Solar Energetic Electrons (SEE) emitted by the Sun. Solar Energetic Electrons (SEE) linked to solar flares arise from small surface explosions, while others are released gradually with Coronal Mass Ejections (CME), huge eruptions of plasma and magnetic fields. The Solar Orbiter flew through electron streams and studied the space environment between the Sun and spacecraft. Understanding SEE and CMEs is crucial for space weather prediction, protecting satellites, GPS, power grids, and astronauts. The mission aims to study the Sun’s 11-year magnetic cycle, corona heating, solar wind formation, and acceleration.

Notes:
Indian Institute of Technology Hyderabad (IIT Hyderabad) signed a Memorandum of Understanding (MoU) with Army Training Command (ATC), Shimla. The partnership establishes a Centre of Excellence (CoE) named VIGRAHA (Virtual, Intelligent, Ground-breaking Research in AR/VR and High-tech Applications for Indian Army). The Simulator Development Division (SDD), Secunderabad represents the Indian Army in this collaboration. The CoE will focus on Augmented Reality (AR), Virtual Reality (VR), Artificial Intelligence (AI), Robotics, unmanned systems, and emerging defense technologies. The initiative strengthens India’s self-reliance (Atmanirbhar Bharat) in defense technologies.

Notes:
A study of fossil leaves from Nagaland revealed how Antarctica influenced the Indian Monsoons. Fossil leaves from the Laisong Formation in Nagaland revealed that the region once had a warm and wet climate with very high rainfall and temperatures. The fossils matched the period when massive ice sheets began forming in Antarctica, showing a global connection. Growth of Antarctic ice reshaped global wind and rainfall patterns by shifting the Intertropical Convergence Zone (ITCZ) toward the tropics. This shift brought intense monsoonal rains to Northeast India and led to the evolution of the monsoon system. The research used CLAMP (Climate Leaf Analysis Multivariate Program) method to analyze fossil leaves. CLAMP treats fossil leaves as “climate fingerprints” to reconstruct past climates.
