Science & Technology Current Affairs MCQs

Notes:
Recent research has identified Candidatus Phytoplasma as the causative agent of a peculiar disease in sesame fields in Midnapore, West Bengal. Sesame, known as the “Queen of Oil,” is an ancient oilseed crop with medicinal properties. The disease causes disfigurement and virescence in the plants, impacting their yield. Researchers, led by Prof. Gaurab Gangopadhyay, have been studying this issue and aim to improve sesame varieties through molecular marker-assisted breeding to combat this threat and enhance the crop’s benefits.

Notes:
Nafithromycin, developed by Wockhardt with support from BIRAC, is India’s first indigenously produced antibiotic targeting antimicrobial resistance (AMR). It is designed to treat Community-Acquired Bacterial Pneumonia (CABP) and is ten times more effective than azithromycin. This significant breakthrough follows 14 years of research and aims to address the global health crisis of AMR, which is responsible for millions of deaths annually. The drug awaits final approval from the Central Drugs Standard Control Organization (CDSCO) for public use.

Notes:
Indian Institute of Science (IISc) introduced STRONG (STring Representation Of Nanopore Geometry), a new language for encoding nanopore shapes as character sequences. STRONG helps machine learning models predict nanopore properties accurately. It assigns letters to atomic configurations, improving understanding of nanopore geometries. This tool supports applications like gas separation and enhances data analysis. STRONG’s integration with neural networks boosts prediction accuracy. This breakthrough marks a significant advancement in materials science and computational research.

Notes:
Black thrips infestation has affected chilli crops in Ballari (Karnataka) and parts of Rayalaseema (Andhra Pradesh). It is an invasive pest species first reported in India in 2015 on papaya. Black thrips damage tender leaves, flowers, and fruits, leading to stunted growth, fruit malformation, and yield loss in crops like chilli, cotton, and mango. It feeds on various plants, including horticultural and ornamental crops. Its spread is due to the lack of natural predators and excessive pesticide use, along with staggered planting practices.

Notes:
The Sabal 20 is a logistics drone designed by EndureAir Systems, incubated at IIT Kanpur. It features advanced Vertical Take-Off and Landing (VTOL) technology, allowing it to operate in rugged terrains with a low noise signature. The drone can carry payloads of up to 20 kg and supports various missions, including long-range deliveries and high-altitude operations. Its development involved significant contributions from professors and students at IIT Kanpur, showcasing India’s advancements in drone technology.

Notes:
TakeMe2Space, a Hyderabad-based firm, will launch India’s first AI lab in space, MOI-TD (My Orbital Infrastructure – Technology Demonstrator), in mid-December 2024 using ISRO’s PSLV C60. The mission will demonstrate real-time data processing in orbit, reducing data transmission costs and latency. MOI-TD addresses the challenge of processing petabytes of data from satellites, bypassing delays caused by cloud cover. The platform will allow users to upload AI models for Earth observation tasks like environmental monitoring. MOI-TD marks a step toward space-based data centers, paving the way for affordable, sustainable space computing solutions.

Notes:
Karnataka Health Minister Dinesh Gundu Rao has directed officials to study Handigodu disease scientifically. Handigodu disease is a rare osteoarthritic disorder (bone and joint disease) found in Shimoga and Chikmaglur districts. It is an inherited degenerative bone and joint disease, first noticed in Handigodu village. Symptoms include severe joint and hip pain, deformation, dwarfism, and difficulty walking. The disease begins in preadolescence and can severely affect mobility. Over 1,000 people have died from the disease since its discovery in 1975. It is similar to Mseleni Joint Disease in South Africa.

Notes:
A female elephant recently died of suspected anthrax at Bandipur Tiger Reserve. Anthrax is caused by Bacteria ‘Bacillus anthracis’, a spore-forming bacterium found in soil. It primarily affects livestock and wild animals through contaminated soil, plants, or water. Humans can contract anthrax by contact with infected animals or their products, contaminated food or water, or spores entering the skin. Anthrax is not contagious between people and occurs in three forms: cutaneous, gastrointestinal, and inhalational. The bacteria’s spores can survive in soil for years, posing long-term risks to animals and humans.

Notes:
The first annual review meeting of Rural Technology Action Group (RuTAG) 2.0 projects was held at SKUAST, Srinagar, Kashmir. RuTAG, launched in 2004 by the Office of the Principal Scientific Adviser (PSA), supports rural development through Science & Technology interventions. It focuses on demand-driven solutions, addressing grassroots technology gaps, upgrading technology, and providing training and demonstrations. RuTAG 2.0, launched in 2023, aims to translate innovations into market-ready products. The initiative seeks to drive transformative changes in rural areas, ensuring sustainable development and empowering communities through accessible and impactful technologies.

Notes:
The third Copernicus Sentinel-1C satellite was launched aboard a Vega-C rocket from Europe’s Spaceport in French Guiana. The Copernicus Programme is an Earth Observation initiative managed by the European Space Agency (ESA) in collaboration with the European Union (EU). It integrates data from satellites, ground stations, airborne, and sea-borne sensors to provide near-real-time information services. The programme offers free and open access to data for various applications. The Sentinel satellites are tailored to meet the needs of Copernicus services in areas like atmosphere, marine, land, climate, emergency response, and security. Copernicus aims to deploy nearly 20 satellites by 2030, funded and managed by the European Commission.
