Science & Technology Current Affairs MCQs

Notes:
IndiaAI Independent Business Division (IBD) and National Cancer Grid (NCG) launched the Cancer AI & Technology Challenge (CATCH) Grant Program. The program supports Artificial Intelligence (AI) solutions for cancer screening, diagnostics, treatment support, and healthcare operations in India. Grants of up to ₹50 lakh per project will be co-funded by IndiaAI and NCG for selected technology–clinical teams.

Notes:
Recently, IIT Roorkee developed a new drug candidate, Compound 3b, to fight deadly drug-resistant bacteria. It targets KPC-2-producing Klebsiella pneumoniae, a World Health Organization (WHO) top-priority superbug. Compound 3b is a β-lactamase inhibitor that stops bacterial enzymes from breaking down antibiotics. It works with the antibiotic Meropenem, restoring its effectiveness against resistant infections. Preclinical lab and animal tests showed major infection reduction in lungs and safety to human cells. It marks a major step against antimicrobial resistance and boosts India’s role in global biomedical research.

Notes:
India’s first government-backed Drone Forensic Laboratory has been set up at Uttar Pradesh State Institute of Forensic Science (UPSIFS), Lucknow. It was inaugurated by Uttar Pradesh Chief Minister Yogi Adityanath. The lab is designed by Milind Raj, known as the “Drone Man of India,” who is now the forensic drone advisor to UPSIFS. The lab enables real-time tracking, decoding, and forensic examination of Unmanned Aerial Vehicles (UAVs). It can identify launch sites, flight paths, payloads, and hazardous materials like explosives.

Notes:
NASA announced that the James Webb Space Telescope (JWST) discovered a new 29th satellite of Uranus, named S/2025 U1. The moon has an estimated diameter of 10 kilometres and orbits Uranus at a distance of about 56,000 kilometres. S/2025 U1 will receive an official name from the International Astronomical Union (IAU) in the future. Uranus is the seventh planet from the Sun and the third-largest planet in the solar system. Uranus is an ice giant, composed mainly of hydrogen, helium, water, methane, and ammonia. Uranus now has 29 moons, with five major moons: Miranda, Ariel, Umbriel, Titania, and Oberon.

Notes:
The Indian Space Research Organisation (ISRO) will launch the first uncrewed Gaganyaan mission (G1) in December 2025. The mission will carry Vyommitra, a female half-humanoid robot. Vyommitra will monitor the module, issue alerts, and manage life-support operations. ISRO plans five launches in 2025 and four in 2026. Upcoming launches include Oceansat-3A, NVS-03 (Navigation Satellite), TDS-01 (Technology Demonstration Satellite), and BlueBird Block 2. ISRO declared 2025 as “Gaganyaan Year” to highlight its human-spaceflight ambitions. The mission is a key step towards India’s future crewed space missions.

Notes:
Gaza has recently reported a surge in Guillain-Barré Syndrome (GBS), raising health concerns. Guillain-Barré Syndrome (GBS) is a rare autoimmune condition where the immune system attacks the peripheral nervous system. The peripheral nervous system controls muscle movement, pain, temperature, and touch sensations. It is also called Acute Inflammatory Demyelinating Polyradiculoneuropathy (AIDP). It commonly affects people between 30 and 50 years of age. It usually follows viral or bacterial infections, vaccination, or surgery.

Notes:
Matanomadh, a remote village in Kutch district, Gujarat, may serve as a test bed for ISRO’s Mangalyaan-2 mission to Mars. Researchers from Space Applications Centre (SAC) Ahmedabad, Savitribai Phule Pune University (SPPU), and Birbal Sahni Institute of Palaeosciences, Lucknow dated jarosite mineral in Matanomadh to 55 million years (Paleocene period). Jarosite is a yellow, iron-rich sulphate mineral, similar to those found on Mars, indicating past water activity. The site allows field-analogue studies for Mars, including rover testing, drilling, geochemistry, and astrobiology research. The discovery can help decode Martian geology, past chemical interactions, and organic molecule trapping, aiding future Mars missions.

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:
India unveiled its first fully indigenous 32-bit microprocessor, Vikram 3201, at Semicon India 2025. It is designed by Vikram Sarabhai Space Center (VSSC) and fabricated by Indian Space Research Organisation’s (ISRO) Semiconductor Laboratory (SCL), Chandigarh. Vikram 3201 is designed specifically for rockets and satellites, unlike processors in smartphones or laptops. It is an upgrade of Vikram 1601, a 16-bit processor used in ISRO launch vehicles since 2009. The processor manages navigation, control, and mission management in launch vehicles. The launch supports India’s semiconductor self-reliance, with five units under construction under the Design-Linked Incentive scheme.

Notes:
Scientists have found that tiny interstellar dust grains act as storytellers of the universe. A team led by the Indian Institute of Astrophysics (IIA), Bengaluru, provided the strongest observational evidence of how these dust grains align with magnetic fields in the Milky Way. Dust grains are a few micrometers in size, made of silicates and carbonaceous material, and exist throughout the interstellar medium. They play a key role in star and planet formation and cause starlight polarization detected since 1949.
