Science & Technology Current Affairs MCQs

Notes:
Recently, Indian researchers identified a key gene in pineapple that can fight the deadly Fusariosis disease. Fusariosis is caused by the fungus Fusarium moniliforme and damages stems, blackens leaves, and rots fruits from inside. It leads to major losses in pineapple farming and makes harvests unreliable. Researchers from Bose Institute under Department of Science and Technology (DST) identified AcSERK3 gene (Somatic Embryogenesis Receptor Kinase). Overexpression of this gene boosted pineapple’s natural immunity.

Notes:
Recently, astronomers observed rocky planet formation for the first time by detecting minerals condensing from vapor around a young star named HOPS‑315. HOPS‑315 is a newborn protostar located 1,300 light-years away in the Orion molecular cloud. It has a rotating protoplanetary disc of gas and dust, tilted in a way that allows Earth-based telescopes to view its inner region clearly. This rare view helped scientists directly witness the earliest stages of rocky planet formation. The minerals found—like forsterite and enstatite—match those in chondritic meteorites on Earth. This discovery closely mirrors how our own Solar System may have formed.

Notes:
Recently, 16 chitals (spotted deer) died at Rajiv Gandhi Zoological Park in Pune due to Foot and Mouth Disease (FMD), as confirmed by lab reports. Foot and Mouth Disease (FMD) is a highly contagious viral disease affecting all cloven-hoofed animals like cattle, goats, sheep, deer, and pigs. It is caused by an aphthovirus from the Picornaviridae family. The World Organisation for Animal Health (WOAH) first gave official recognition to this disease.

Notes:
Recently, India and the United States marked their first space collaboration with the successful launch of NISAR (NASA-ISRO Synthetic Aperture Radar) by ISRO’s GSLV-F16 rocket. GSLV (Geosynchronous Satellite Launch Vehicle) injected NISAR into the Sun Synchronous Polar Orbit (SSPO) at around 745 km altitude in a 19-minute flight. The NISAR (NASA-ISRO Synthetic Aperture Radar) is the world’s first Earth observation satellite mission between the National Aeronautics and Space Administration (NASA) and the Indian Space Research Organisation (ISRO). It will study land deformation, ice movement, ecosystems, and oceanic regions with high precision.

Notes:
Huntington’s Disease (HD) is not yet included in the rare disease category under the National Policy for Rare Diseases despite demands from patients and caregivers in 2024. It is a genetic condition that affects brain cells, causing them to slowly lose function and die. It is inherited, with a 50% chance of passing from an affected parent to a child. It impacts brain regions controlling voluntary movement, memory, thinking, and decision-making, including the basal ganglia and cortex.

Notes:
Seaweed farming has emerged as a potential Blue Carbon strategy, but empirical estimates of carbon burial from these farms are still limited. Blue Carbon refers to organic carbon captured and stored by oceans in vegetated coastal ecosystems such as mangrove forests, saltmarshes, and seagrass meadows. The term “Blue” highlights the watery nature of this carbon storage. Most blue carbon is carbon dioxide dissolved directly into the ocean. These ecosystems cover 2% of the ocean surface but account for 50% of the ocean’s carbon absorption. Blue carbon ecosystems are crucial for global climate change mitigation.

Notes:
On 21 August 2025, the Indian Council of Medical Research (ICMR) launched CEREBO, a portable non-invasive device to detect traumatic brain injuries (TBI). It uses near-infrared spectroscopy with machine learning to identify intracranial bleeding and edema within one minute, giving colour-coded, radiation-free results. The device is safe for infants and pregnant women and can be operated by paramedics or unskilled staff with just 30 minutes of training. It was developed by ICMR, AIIMS Bhopal, NIMHANS Bengaluru and Bioscan Research. India records over 1 lakh deaths and 10 lakh serious head injuries annually, making early TBI detection critical.

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:
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:
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.
