Science & Technology Current Affairs MCQs

Notes:
Indian scientists from Centre for Nano and Soft Matter Sciences, Bengaluru under Department of Science and Technology (DST) developed a solar-powered energy storage device that captures and stores energy in a single unit. The device is known as a photo-rechargeable supercapacitor. Unlike conventional systems, it combines energy harvesting and storage, reducing cost, energy loss, system complexity, and footprint. It enables portable, wearable, off-grid applications, reduces reliance on fossil fuels and conventional batteries, and works in remote areas.

Notes:
Ministry of Science and Technology launched the BIRAC-Research, Development and Innovation Fund in New Delhi for biotechnology and related sectors. The fund aims to promote deep tech innovations and indigenous manufacturing with national impact. India’s bioeconomy has grown significantly over the past decade, from $8 billion in 2014. The launch reflects a government approach under Prime Minister Narendra Modi, positioning India for a global role in biotechnology. The number of biotechnology startups in India has increased to nearly 11,000 today.

Notes:
Sarvam AI, a Bengaluru-based startup, unveiled its flagship sovereign Artificial Intelligence models Sarvam 30B and Sarvam 105B at the IndiaAI Impact Summit 2026. These are considered India’s first large-scale foundational Large Language Models (LLMs) developed domestically, marking a major step toward AI self-reliance. Both models are open-source, promoting transparency, innovation, and wider adoption by developers and institutions. The models are optimised for 22 Indian languages across 11 primary scripts, supporting linguistic diversity and digital inclusion.

Notes:
Health and Family Welfare Minister Jagat Prakash Nadda launched indigenous Tetanus and Diphtheria vaccine at Central Research Institute, Kasauli in Solan district, Himachal Pradesh. Vaccine supports vision of Atmanirbhar Bharat in health sector. India is known as Pharmacy of the World. Universal Immunization Programme (UIP) is world’s largest immunization programme. Central Research Institute will supply 5.5 million vaccine doses by April 2026 to strengthen immunization coverage.

Notes:
Google launched Nano Banana 2, its new Artificial Intelligence image generation and editing tool. It is also called Gemini 3.1 Flash Image and replaces Nano Banana Pro with faster performance and high-quality results. It improves text rendering, subject consistency and real-time web content integration. It is integrated across Google Search AI Mode, Google Lens, AI Studio, Gemini Application Programming Interface and Vertex AI. It is available in 141 more countries including India.

Notes:
A recent study has warned that more than one-third of Africa is at risk of the spread of Cassava Brown Streak Disease (CBSD), which is a highly destructive disease affecting cassava crops. CBSD is considered one of the most devastating diseases of cassava, as it severely reduces both the production and quality of cassava tubers (roots), which are an important staple food in many African countries. The disease was first identified in the mid-20th century in the coastal regions of East Africa, and since then it has spread significantly across the African continent.

Notes:
Entomologists discovered two new species of fruit flies named Acidoxantha paratotoflava and Hemilea suneriae in the Himalayan foothills of Solan district in Himachal Pradesh. Acidoxantha paratotoflava is a medium-sized greenish-yellow fly with four black stripes on its thorax and large black spots on its abdomen. The species also has distinct hook-like structures in the male anatomy, which help in identification. Hemilea suneriae is a reddish-brown fruit fly with prominent black dots on its body. It has a unique wing pattern with a single clear “window” (hyaline indentation) in a dark wing area, unlike related species that usually have two. The discovery adds to India’s insect biodiversity and improves scientific knowledge of fruit fly taxonomy.

Notes:
U.S. drugmaker Pfizer and France’s Valneva reported that their experimental Lyme disease vaccine showed over 70% efficacy in a late-stage trial. Lyme disease, or Lyme borreliosis, is caused by the bacteria Borrelia burgdorferi. It affects the skin, nervous system, heart, and joints. The disease is named after Lyme, Connecticut, United States, where it was first identified in children in 1976. Lyme disease is common in North America, Europe, and parts of Asia. It is transmitted to humans through deer ticks (black-legged ticks) found in grassy, wooded, or bushy areas. Not all tick bites cause Lyme disease, and it cannot spread between humans or from pets.

Notes:
Chief Minister N Chandrababu Naidu unveiled a plan to develop Amaravati as a global hub for quantum computing.
The initiative, Amaravati Quantum Valley (AQV), aims to place Andhra Pradesh among the top 5 global quantum hubs by 2030, leveraging the National Quantum Mission. The first quantum computer is set to be launched on April 14, marking a major milestone. The ecosystem will include hardware manufacturing, algorithm development, research, and innovation labs, supported by 8 dedicated research towers. The state plans to develop core technologies locally (cryogenics, photonics, advanced electronics) to reduce import dependence and achieve end-to-end capabilities.

Notes:
As part of Gaganyaan mission, the Indian Space Research Organisation is conducting Mission MITRA (Mapping of Interoperable Traits and Response Assessment) in Leh from April 2 to April 9, 2026. Mission MITRA is a first-of-its-kind team behavioral study, developed jointly by ISRO and the Institute of Aerospace Medicine, aimed at evaluating crew safety and performance in human spaceflight. The study focuses on team communication, adaptability to stress, psychological resilience, and mutual support, which are critical for mission success. Leh’s high-altitude environment (approx 3,500 metres), hypoxia, low temperature, and isolation serve as a natural analog for spaceflight operations.
