Science & Technology Current Affairs MCQs

Notes:
In Punjab, incessant rainfall and floods stopped farmers from spraying anti-fungal medicines. This has led to the emergence of false smut disease, locally called haldi rog, in paddy crops. False smut is a major fungal disease of rice caused by Ustilaginoidea virens. The fungus attacks during the flowering stage, but symptoms appear after panicle emergence. Infected grains show black fungal growth, later covered with yellow fungal mass. It reduces seed germination and significantly lowers yield depending on infection level.

Notes:
The death toll in the stampede at Tamilaga Vetri Kazhagam (TVK) rally in Velusamypuram has risen to 41. Doctors reported most fatalities were due to compressive asphyxia caused by crowd crush. Asphyxia occurs when the body does not get enough oxygen. Respiration moves oxygen into the lungs and circulates it via blood to all body cells, while carbon dioxide is removed. Lack of oxygen can cause unconsciousness or death. Compressive asphyxia happens when an external force prevents chest expansion, crushing the lungs and stopping breathing. This can occur in crowded situations or from a person’s weight on the chest.

Notes:
Maldives has become the first country in the world to achieve triple elimination of mother-to-child transmission of hepatitis B, HIV, and syphilis. The World Health Organization (WHO) has validated Maldives for eliminating mother-to-child transmission of hepatitis B. According to WHO, around 25,000 HIV-positive pregnant women globally need treatment to prevent transmission to babies. Hepatitis B still affects over 42 million people in the WHO Southeast Asia Region. In Maldives, over 95% of pregnant women receive antenatal care with almost universal testing for HIV, syphilis, and hepatitis B.

Notes:
On October 13, 2025, TechBharat Research Foundation (TBRF) and Google Cloud India launched India’s first Artificial Intelligence (AI) Centre of Excellence (CoE) for Public Good in Visakhapatnam, Andhra Pradesh (AP). The initiative was supported by the Government of Andhra Pradesh, particularly its Department of Information Technology, Electronics & Communications (IT, E&C). A Memorandum of Understanding (MoU) was signed between the Government of Andhra Pradesh and TechBharat Research Foundation (TBRF) for setting up and operating the CoE. TBRF will lead the CoE as a hub for applied AI research and public service solutions. Google Cloud India will provide cloud infrastructure, Gemini AI models, tools, mentorship, and market support.

Notes:
On October 12, 2025, Uttarakhand Chief Minister Pushkar Singh Dhami inaugurated newly developed pulse and barley varieties at the 118th All India Farmers Fair and Agricultural Industry Exhibition held at GB Pant University of Agriculture and Technology (GBPUAT) in Uttarakhand. The varieties were developed by GBPUAT students to improve crop productivity and farmer income. Pant Urd-13 and Pant Urd-14 are improved urdbean (black gram) varieties with higher yield and better disease resistance. Pant Matar 554 is a high-yielding pea variety designed to enhance farmers’ earnings. Pant Jau 1106 is a new barley variety introduced to diversify crop options for farmers in the region.

Notes:
Researchers recently found that carabid ground beetles can act as bioindicators to track soil microplastics. They are commonly called ground beetles and belong to the Carabidae family. These beetles play a key role in the food web as both predators and prey species. They live in diverse habitats such as forests, grasslands, agricultural fields, wetlands, and urban areas. They thrive in temperate to tropical climates. Ecologically, they help in biological pest control and now aid in monitoring soil pollution.

Notes:
The Anusandhan National Research Foundation (ANRF), in collaboration with Indian Council of Medical Research (ICMR) and the Gates Foundation, launched the Mission for Advancement in High-Impact Areas (MAHA)-Medical Technology recently. MAHA MedTech Mission aims to boost innovation in India’s medical technology sector, reduce dependence on high-cost imports, and ensure affordable, high-quality medical technologies. The mission supports development and commercialization of innovative and affordable MedTech solutions.

Notes:
In November 2025, the World Health Organization (WHO) confirmed an outbreak of Rift Valley Fever (RVF) in Mauritania and Senegal, Western Africa. Rift Valley Fever is caused by a Phlebovirus from the Phenuiviridae family. It mainly affects animals such as sheep, goats, cattle, and camels. Humans get infected through contact with infected animals or mosquito bites. It does not spread from person to person. The disease was first identified in Kenya’s Rift Valley in the 1930s. It later spread across sub-Saharan Africa, Egypt, Saudi Arabia, and Yemen.

Notes:
In November 2025, Union Minister of State Dr. Jitendra Singh launched India’s first indigenous high-precision compact diode laser at the Emerging Science, Technology and Innovation Conclave 2025 (ESTIC 2025) held at Bharat Mandapam, New Delhi. The laser enables quantum-encrypted communication using Quantum Key Distribution (QKD), strengthening cybersecurity for financial and banking transactions. It is developed by Prenishq Pvt. Ltd., a startup supported by the National Quantum Mission (NQM), along with contributions from IIT-Delhi. The system offers high beam quality, strong stability, long-term reliability, and easy integration with lab and industrial setups.

Notes:
Google inaugurated its largest Artificial Intelligence (AI) infrastructure hardware engineering centre outside the US in Taipei, Taiwan. The centre will focus on AI infrastructure hardware engineering for Google’s global operations. Technology developed and tested at the centre will be deployed across Google’s global data centres. These AI systems support billions of Google devices and services worldwide. The centre reinforces Taiwan’s role as a key hub for global AI innovation.
