Science & Technology Current Affairs MCQs

Notes:
Meta Platforms has chosen Mumbai and Visakhapatnam as landing sites for its undersea cable project named Waterworth. Undersea cables are fiber-optic cables laid on the ocean floor to transmit information globally. They form the backbone of the international internet. Around 90% of global data and 80% of world trade are carried through undersea cables. They also facilitate approximately $10 trillion of financial transactions annually. The project will strengthen India’s connectivity with global digital networks and support faster internet and data services.

Notes:
India has recently developed its first indigenously discovered antibiotic, Nafithromycin. It was developed with support from the Biotechnology Industry Research Assistance Council (BIRAC). The antibiotic is marketed under the trade name “Miqnaf.” It is the first molecule fully conceptualized, developed, and clinically validated in India. Nafithromycin addresses Antimicrobial Resistance (AMR) and is effective against resistant respiratory infections. It is especially useful for cancer patients and poorly controlled diabetics. The drug treats Community-Acquired Bacterial Pneumonia (CABP) and targets both typical and atypical pathogens. No similar antibiotic in this class has been developed globally for over 30 years.

Notes:
Kerala reported another death from Amoebic Meningoencephalitis (Primary Amebic Meningoencephalitis, PAM), raising the 2025 toll to 27 cases. Primary Amebic Meningoencephalitis is a rare, fatal brain infection caused by the free-living amoeba Naegleria fowleri, known as the “brain-eating amoeba.” Infection occurs when contaminated freshwater enters the nasal cavity, allowing the amoeba to reach the brain via the olfactory nerve. It is found in warm freshwater and soil, especially lakes, rivers, hot springs, and unchlorinated pools.

Notes:
Scientists at the National Institute of Animal Nutrition and Physiology (NIANP), Bengaluru, under the Indian Council of Agricultural Research (ICAR), have developed CRYODIL. CRYODIL is a ready-to-use, egg yolk-free semen extender for buffaloes. It is the first such solution developed in India for buffalo semen cryopreservation. It has a long shelf life of 18 months or more. The post-thaw progressive motility of sperm in CRYODIL is significantly higher than in traditional egg-yolk-based extenders. It improves sperm movement and viability after freezing and thawing, increasing fertilisation success.

Notes:
China developed the underwater drone nicknamed the “ghost jellyfish”. The drone is made of a soft hydrogel material, has a transparent body, and uses electrostatic hydraulic actuators to mimic the natural, silent movement of a real jellyfish. It is equipped with an AI chip and a micro-camera for real-time object identification and can operate with very low energy consumption. Its primary uses are for stealthy underwater reconnaissance, ecological monitoring, and observing marine life without causing disruption.

Notes:
In October 2025, scientists discovered a new exoplanet named GJ 251c, located less than 20 light-years from Earth. The discovery was made by an international team, including researchers from Penn State University (PSU), USA. The finding was published in The Astronomical Journal. GJ 251c is a super-Earth, about four times the mass of Earth and likely rocky in composition. It was detected using the radial-velocity method, with data from the Habitable Zone Planet Finder (HPF) at PSU’s Hobby-Eberly Telescope (HET). The discovery provides key insights into planetary formation and the search for potentially habitable exoplanets.

Notes:
The Postgraduate Institute of Medical Education and Research (PGIMER), Chandigarh has reported a sharp rise in infections caused by Bacterium Bordetella holmesii in North India. This bacterium mimics whooping cough (pertussis), making diagnosis difficult. Bordetella holmesii was first identified in 1995. It is a gram-negative coccobacillus capable of causing pertussis-like respiratory illness. Besides cough infections, it can cause endocarditis, pneumonia, cellulitis, arthritis, and pyelonephritis. The recent surge highlights the need for improved diagnostic tests and public health awareness to differentiate it from regular whooping cough infections.

Notes:
In November 2025, Google announced ‘Project Suncatcher,’ a research initiative to create a solar-powered, space-based AI infrastructure system. The project aims to use Tensor Processing Units (TPUs) aboard satellites in low-Earth orbit (LEO) to explore machine learning scalability. It will use Trillium TPUs designed to withstand up to 15 krad(Si) radiation and advanced thermal radiators to manage heat. In partnership with Planet Labs, two prototype satellites will launch in 2027 to test AI performance and optical communication. Solar-powered satellites will operate in a sun-synchronous dawn-dusk orbit, generating up to 8 times the power of ground-based installations

Notes:
In a historic milestone, Prime Minister Narendra Modi unveiled NexCAR19, India’s first indigenous CAR-T Cell Therapy, at the Emerging Science, Technology & Innovation Conclave (ESTIC) 2025 in Delhi. It is developed by ImmunoACT, an IIT Bombay spin-off. It is supported by the Department of Biotechnology (DBT) and Biotechnology Industry Research Assistance Council (BIRAC). NexCAR19 is the world’s first humanised CAR-T therapy, truly “Made in India, for the world.” CAR-T Cell Therapy is an immunotherapy that reprograms a patient’s immune cells to fight blood cancers like Acute Lymphocytic Leukemia (ALL).

Notes:
Recently, researchers found that male and female brains respond differently as Batten Disease progresses, opening new paths for treatment. Batten Disease is a rare genetic disorder affecting the brain and nervous system. It is congenital, progressive, and terminal, leading to steady decline in nervous system function. Symptoms include loss of vision and seizures, beginning in infancy, childhood, or rarely adulthood. Life expectancy varies from early childhood to the twenties depending on the form.
