Science & Technology Current Affairs MCQs

Notes:
Recently, the World Health Organisation (WHO) certified Kenya as having eliminated human African trypanosomiasis (HAT), also known as sleeping sickness. It is a parasitic disease spread by infected tsetse fly bites, endemic in sub-Saharan Africa. It has two forms: Trypanosoma brucei gambiense (92% cases, chronic, found in West and Central Africa) and Trypanosoma brucei rhodesiense (8% cases, acute, found in East and Southern Africa). Rural communities relying on farming, fishing, herding, or hunting face higher risk. WHO has validated the gambiense form’s elimination in Togo, Benin, Ivory Coast, Uganda, Equatorial Guinea, Ghana, Chad, Guinea, and now Kenya.

Notes:
The Department of Animal Husbandry & Dairying (DAHD) under the Ministry of Fisheries, Animal Husbandry & Dairying has recently issued the Revised National Action Plan on Glanders. Glanders is caused by the bacterium Burkholderia mallei and mainly affects equines like horses, mules, and donkeys, with risks to other animals and humans. It causes nodules and ulcerations in the respiratory tract and lungs, with a skin form known as farcy. Transmission occurs through contaminated food or water, infected harness equipment, or horse meat. It is a World Organisation for Animal Health (WOAH)-listed disease and must be notified under the WOAH Terrestrial Animal Health Code.

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.

Notes:
Turakapalem village in Guntur, Andhra Pradesh, has seen 29 deaths due to Melioidosis. It is caused by the Gram-negative bacterium Burkholderia pseudomallei found in soil and water. The government has declared a public health emergency in the area. The disease is seasonal, with 75–85% of cases during the rainy season. It has a high case fatality rate (CFR) of 16% to 50% in endemic regions. Endemic areas include Southeast Asia, northern Australia, Indian subcontinent, southern China, Hong Kong, and Taiwan. Currently, no vaccine is available, but early diagnosis and treatment are crucial.

Notes:
ISRO Chief V. Narayanan announced that a half-humanoid robot Vyommitra will be sent in December 2025 as part of the first uncrewed Gaganyaan mission. Two more uncrewed missions are planned in 2026 before sending India’s first astronaut, Gaganyatri, to space in early 2027. ISRO successfully conducted the first Integrated Air Drop Test (IADT-01) for the parachute-based deceleration system with support from the Indian Air Force, DRDO, Navy, and Coast Guard. Human Rated Launch Vehicle (HLVM3), Crew Escape System, and propulsion systems have been tested.

Notes:
Indian Immunologicals Limited (IIL) has launched India’s first indigenously developed glycoprotein E (gE) deleted DIVA (Differentiated between Infected and Vaccinated Animal) marker vaccine against Infectious Bovine Rhinotracheitis (IBR) in Anand, Gujarat. IBR is caused by Bovine Herpes Virus-1 (BHV-1), belonging to the genus Varicellovirus under Alphaherpesvirinae subfamily. It mainly affects domestic and wild cattle. The disease has three forms – respiratory, genital and encephalitic, with respiratory and genital being common. Transmission occurs through aerosols and semen from bulls to milch animals, impacting the reproductive system.

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:
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:
Google announced that its quantum processor Willow has achieved the first “verifiable” quantum advantage. Quantum advantage means a quantum computer can outperform a classical computer in practice. The announcement was accompanied by an open-access paper in Nature by the Google Quantum AI and Collaborators team. Willow ran a new algorithm, Quantum Echoes, 13,000 times faster than the best classical algorithm on a supercomputer. The experiment used a technique called out-of-time-order correlator (OTOC) to track how information scrambles in quantum systems. OTOC measures how quantum information spreads, is scrambled, and can be “unscrambled” using time-reversal. Willow’s processor precisely controlled quantum bits (qubits) in a chaotic quantum system for the experiment.

Notes:
The Indian Space Research Organisation (ISRO) successfully launched the LVM3-M5 rocket from Satish Dhawan Space Centre, Sriharikota at 5:35 pm. The rocket carried CMS-03, India’s heaviest communication satellite weighing 4,400 kilograms. It was the fifth operational flight of the Launch Vehicle Mark-3 (LVM3) launcher. CMS-03 was launched into a Geosynchronous Transfer Orbit (GTO). The satellite will provide multi-band communication services across India and nearby ocean regions. It will enhance secure data, voice, and video connectivity for civilian and strategic applications. The mission highlights India’s capability in heavy satellite launches and strengthens its communication network.
