Science & Technology Current Affairs MCQs

Notes:
Indian Council of Agricultural Research–Indian Veterinary Research Institute produced Sahiwal calves using OPU–IVF–ET (Ovum Pick-Up–In Vitro Fertilization–Embryo Transfer). Sahiwal cattle is one of the best milk-producing indigenous breeds of India. It originates from Sahiwal region in Montgomery district of Punjab in Pakistan. It is also known as Lambi Bar, Lola, Montgomery, Multani and Teli. The cows are brownish-red in colour with shades from mahogany to greyish red, while bulls have darker extremities.

Notes:
Delhi government and Indian Institute of Technology Madras are studying “smog-eating” photocatalytic road coatings to reduce air pollution. The coating neutralizes harmful gases like nitrogen dioxide and volatile hydrocarbons present in polluted air. It mainly uses Titanium dioxide which is low-cost, chemically stable and compatible with construction materials. Titanium dioxide-based materials help in gaseous depollution and environmental cleaning. Photocatalysis works by using light energy to break down harmful pollutants and organic waste into less toxic or harmless substances. This process helps improve air quality and contributes to cleaner environment.

Notes:
The Minor Planet Centre (MPC) recently announced discovery of 15 new moons, 4 around Jupiter and 11 around Saturn. It is the global centre for collecting and storing data on small solar system bodies. It operates under the International Astronomical Union (IAU) at the Smithsonian Astrophysical Observatory in Cambridge, Massachusetts, United States. Astronomers send new findings to MPC, where data is verified and orbits are calculated. It assigns official names or designations to newly discovered objects. It tracks asteroids, comets, and outer planet moons.

Notes:
India supplied 13 tonnes of Bacille Calmette-Guérin (BCG) vaccines and related materials to Afghanistan’s Ministry of Public Health. The Bacille Calmette-Guérin (BCG) vaccine is a live attenuated vaccine used to protect against tuberculosis (TB). It is the only licensed vaccine for TB and is widely administered to newborns worldwide. The vaccine was developed by Albert Calmette and Camille Guérin at the Pasteur Institute and first used in 1921. Its main aim is to prevent severe childhood TB, including TB meningitis and disseminated TB. It also provides partial protection against diseases like leprosy and Buruli ulcer.

Notes:
Scientists at CSIR National Institute for Interdisciplinary Science and Technology have developed “Designer Rice,” a functional food to address malnutrition. It is created by processing broken rice into flour, enriching it with protein, fibre, and micronutrients like iron, folic acid, and vitamin B12, and reforming it into rice-like grains. The technology has been transferred to Tata Consumer Products Limited for large-scale production. Unlike regular rice, it has higher protein (over 20%) and a low glycemic index (below 55). It helps manage blood sugar levels, making it beneficial for diabetics.

Notes:
China has announced the discovery of a new lunar mineral named Cerium-Magnesium Changesite, adding to knowledge of extraterrestrial materials and lunar geology. The mineral was identified in a lunar meteorite called Pakepake 005, the first such meteorite found in China. This meteorite is a small spherical rock weighing about 44 grams with a dark molten outer layer. The mineral itself is colourless, transparent, and brittle, yet scientifically significant. It shows fluorescent properties, meaning it can emit light under certain conditions. This fluorescence has potential applications in advanced technologies like next-generation LED materials.

Notes:
DAMPE Satellite has made observations on the acceleration of cosmic rays. The findings show that the intensity of cosmic radiation decreases sharply beyond a certain high-energy threshold. DAMPE stands for Dark Matter Particle Explorer and is also known as “Wukong.” It was developed by the Chinese Academy of Sciences (CAS). It is China’s first astronomical satellite designed for high-energy observations. The satellite was launched in 2015 into a polar sun-synchronous orbit at an altitude of about 500 km. It detects high-energy gamma rays, electrons, and cosmic rays.

Notes:
Scientists have warned that rising temperatures due to climate change may increase the spread of the Brain-Eating Amoeba, scientifically known as Naegleria fowleri. The amoeba is commonly found in warm freshwater bodies such as lakes, rivers, ponds, hot springs, and moist soil. It enters the human body through the nose and attacks brain tissues. Infection by Naegleria fowleri causes Primary Amebic Meningoencephalitis (PAM), a rare but highly fatal disease of the central nervous system. Higher temperatures create favourable conditions for the amoeba’s growth and survival. The warning highlights the possible health impacts of climate change on infectious diseases.

Notes:
Dhruva Space secured ₹105 crore under the Research, Development & Innovation Fund for “Project Garud.” Project Garud is a satellite platform programme focused on developing a flat-pack 500 kg-class satellite platform for scalable and high-volume manufacturing. The project aims to bridge the gap between small experimental satellites and large traditional spacecraft systems. The platform is designed for applications in telecommunications, national security, Earth observation, and data-driven services. Its flat-pack architecture enables efficient launch stacking, faster integration, and quicker deployment timelines.

Notes:
A fresh outbreak of Ebola has been reported in the Ituri province of the Democratic Republic of the Congo, with dozens of deaths reported. Ebola is a severe viral hemorrhagic fever caused by orthoebolaviruses and affects humans as well as non-human primates. The disease was first identified in 1976 in Sudan and the Democratic Republic of Congo. It spreads through direct contact with infected blood, body fluids, organs, or contaminated surfaces, but not through air transmission. Fruit bats are considered the natural hosts of the virus.
