Science & Technology Current Affairs MCQs

Notes:
Chandrayaan-3’s lander payload RAMBHA-LP (Radio Anatomy of Moon Bound Hypersensitive Ionosphere and Atmosphere – Langmuir Probe) detected an active plasma environment in the Moon’s south polar region. Plasma, the 4th state of matter, is electrically neutral and contains charged particles like ions and free electrons. RAMBHA-LP uses a hypersensitive Langmuir probe mounted on a boom to avoid interference from the lander. It measures electron density and electron temperature near the lunar surface, helping understand the plasma behaviour at the Moon’s South Pole.

Notes:
Researchers at the Indian Institute of Technology Delhi have developed an ingestible device that can directly sample bacteria from the small intestine. The innovation helps overcome limitations of current methods like endoscopy or stool analysis, which do not accurately reflect upper gut conditions. The pill-sized device remains closed in the stomach and opens only in the intestine to collect bacterial samples, then reseals safely. It uses an enteric-coated gelatin cap that dissolves at intestinal pH, allowing fluid and microbes to enter sampling chambers. The study was conducted in collaboration with the All India Institute of Medical Sciences Delhi and funded by the Indian Council of Medical Research.

Notes:
The Minister of Fisheries, Animal Husbandry and Dairying informed Rajya Sabha about white spot disease. It is a highly contagious viral infection affecting crustaceans like prawns, yabbies and crabs. It is caused by White Spot Syndrome Virus (WSSV). All decapod crustaceans (order Decapoda) from marine, brackish and freshwater environments are susceptible.

Notes:
National Aeronautics and Space Administration (NASA) has lost contact with the Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft. MAVEN is a Mars orbiter that studied how the planet’s atmosphere escapes into space for over ten years. It is the first mission dedicated to studying the upper atmosphere of Mars. It is part of NASA’s Mars Exploration Program to understand Mars and its past habitability. The mission studied how atmospheric loss changed Mars’s climate over time.

Notes:
The Indian Computer Emergency Response Team (CERT-In) warned about a new cyber threat targeting WhatsApp users called GhostPairing. GhostPairing is a hacking technique where attackers secretly link their device to a victim’s WhatsApp account. It allows near-complete access without passwords, SIM swap, or user awareness. Hackers gain control by tricking users into entering WhatsApp pairing codes. The attack starts with a message from a trusted contact saying, “Hi, check this photo.” The message contains a link with a Facebook-style preview. The link opens a fake Facebook viewer asking users to verify to see the content. Victims are prompted to enter their phone number and code. This process unknowingly gives attackers full control of the WhatsApp account.

Notes:
Recent re-analysis of National Aeronautics and Space Administration (NASA) Cassini spacecraft data suggests that Saturn’s moon Titan may not have a subsurface ocean as earlier believed. Titan is the largest moon of Saturn and the second largest in the solar system after Ganymede. It was discovered by Dutch astronomer Christiaan Huygens. Titan has a radius of about 2,575 kilometres and is much wider than Earth’s Moon. It is the only moon with a dense atmosphere, mainly nitrogen with some methane. Titan is the only world besides Earth with rivers, lakes, and seas of liquid on its surface. It has an Earth-like methane cycle with rain, flow, and evaporation.

Notes:
Abu Dhabi, United Arab Emirates (UAE),’s Sheikh Khalifa Medical City became the first hospital worldwide to administer ITVISMA gene therapy. ITVISMA is a one-time gene therapy for spinal muscular atrophy (SMA), given on 28 December 2025. It replaces the defective Survival Motor Neuron 1 (SMN1) gene. This enables production of survival motor neuron protein, targeting the root genetic cause. It is approved for patients aged two years and above, including adults. Spinal Muscular Atrophy (SMA) is a rare, progressive neuromuscular disorder causing muscle weakness and life-threatening complications. The therapy may improve motor function and reduce long-term treatment dependence.

Notes:
Army Hospital (Research and Referral), Delhi, performed India’s first 3D Flex Aqueous Angiography with iStent. The procedure combines advanced imaging with minimally invasive glaucoma surgery. Glaucoma is a leading cause of irreversible blindness with silent progression. The surgery used a stand-mounted Spectralis system and a 3D operating microscope. The breakthrough allows real-time visualization of aqueous outflow pathways. Surgeons can deliver precise, targeted interventions, improving patient outcomes. The procedure positions Armed Forces Medical Services at the forefront of global ophthalmic care.

Notes:
Recently, the Defence Research and Development Organisation (DRDO) developed a portable desalination device named Sea Water Desalination System (SWaDeS). It is designed to meet drinking water needs of soldiers in remote and field conditions. The system can be manually operated or engine-driven and was developed by Defence Laboratory, Jodhpur for Tri-command services. The manual version can be carried by one person and supports 10–12 personnel during emergencies. It is suitable for naval operations, coastal areas, and inland saline regions like Pangong Tso in Ladakh.

Notes:
ISRO’s maiden home-made dust detector, Dust EXperiment (DEX), detects interplanetary dust particles (IDPs) striking Earth roughly every 1,000 seconds. DEX is the first Indian-made instrument designed to study high-speed interplanetary dust particles (IDPs) . Interplanetary Dust Particles are microscopic fragments originating from comets and asteroids. The instrument was flown on the POEM (PSLV Orbital Experimental Module) of PSLV-C58. Dust EXperiment (DEX) was developed by the Physical Research Laboratory (PRL), Ahmedabad.
