Science & Technology Current Affairs MCQs

Notes:
A team at National Institute of Technology (NIT) Calicut has recently developed a low-cost, highly sensitive point-of-care device for early detection of sepsis. The device uses an electrochemical biosensor to detect endotoxins, which are key biomarkers of infection from Gram-negative bacteria. Sepsis is a life-threatening condition that can cause organ failure, shock, and even death if not treated early. The device can detect Lipopolysaccharide (LPS), a toxic component of bacterial membranes, within 10 minutes using blood serum.

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:
In July 2025, ISRO announced that the NASA-ISRO NISAR satellite has been mounted on the Geosynchronous Satellite Launch Vehicle (GSLV) ahead of its launch. All systems of the rocket have been successfully checked. NASA-ISRO Synthetic Aperture Radar (NISAR) is a joint mission between the National Aeronautics and Space Administration (NASA) and ISRO to study Earth’s changing ecosystems. GSLV is developed by the Indian Space Research Organisation (ISRO) to launch satellites into Geosynchronous Transfer Orbits (GTOs). It can carry heavier payloads than the Polar Satellite Launch Vehicle (PSLV).

Notes:
Recently, African Swine Fever (ASF) outbreak was confirmed at a pig farm in Ravas Brahmanan village, Patiala, Punjab. District authorities have taken immediate action to contain the spread. African Swine Fever (ASF) is a highly contagious viral disease affecting domestic pigs and wild boars. It does not affect humans or other animal species. It causes high mortality (up to 90–100%) and severely impacts pig farming. It originated in sub-Saharan Africa and has spread to Europe, Asia, and Africa. In India, it was first detected in Arunachal Pradesh and Assam in Feb–Mar 2020.

Notes:
Indian Space Research Organisation (ISRO) plans to launch the Block 2 BlueBird communication satellite in 3–4 months. BlueBird is developed by U.S.-based AST SpaceMobile. The launch will take place from Satish Dhawan Space Centre, Sriharikota, using Launch Vehicle Mark-3 (LVM3), formerly GSLV-Mk III. This follows ISRO’s successful launch of NASA ISRO Synthetic Aperture Radar (NISAR) mission on July 30 using GSLV. BlueBird is an advanced American satellite designed for direct smartphone-to-satellite communication. It enables users to make calls and access internet directly from space without ground towers.

Notes:
Researchers at Indian Institute of Technology-Madras (IIT-M) developed an agriculture waste-based packaging material. It offers a sustainable alternative to plastic foams like Expanded Polystyrene (EPS). Fungi such as Ganoderma lucidum (medicinal mushroom) and Pleurotus ostreatus (edible mushroom) were grown on waste. Five substrates were used: cardboard, sawdust, paper, cocopith, and hay. Ganoderma on cardboard showed higher compressive strength than EPS. India generates over 350 million tonnes of agricultural waste annually. This innovation can help reduce four million tonnes of plastic waste produced in India.

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:
Odisha Chief Minister Mohan Charan Majhi unveiled India’s first Integrated Global Financial Technology Capability Hub (I-GFTCH) in Bhubaneswar under the BharatNetra initiative. It is launched with Singapore-headquartered Global Finance and Technology Network (GFTN). It aims to promote entrepreneurship, industry-ready skills, inclusive finance, and employment. Odisha plans Deep Neural Network laboratories and centres of excellence to boost research and development (R&D). The state produces 1.8 lakh graduates annually and is first in India to implement an Artificial Intelligence (AI) policy. A dedicated FinTech and Global Capability Centre (GCC) policy will attract global investments.

Notes:
Acanthamoeba, a free-living amoeba, is now a public health concern in Kerala causing eye (keratitis) and brain infections (amoebic meningoencephalitis). Acanthamoeba is a free-living amoeba found in water, soil, dust, swimming pools, hot tubs, and drinking water systems. It can also exist in humidifiers and heating, ventilation, and air conditioning (HVAC) systems. It causes infections in brain, skin, eyes, and sinuses. It enters through cuts, wounds, inhalation, or contact lens use.

Notes:
Researchers at S. N. Bose National Centre for Basic Sciences (SNBNCBS) discovered protein p47’s new role as a “mechanical chaperone.” P47 is a cofactor protein known for assisting p97 in protein trafficking, degradation, and membrane fusion. Study revealed p47 boosts mechanical efficiency of protein extraction from endoplasmic reticulum (ER) to cytoplasm. It stabilizes polypeptides under stress, guides them through pores, prevents misfolding, and improves translocation. This is the first single-molecule evidence of autonomous, force-dependent chaperone-like activity by p47. Discovery opens new therapeutic possibilities for diseases linked to protein instability.
