Science & Technology Current Affairs MCQs

Notes:
China is experiencing an outbreak of respiratory infectious diseases, including rhinovirus and human metapneumovirus (HMPV). HMPV cases, especially among children under 14 in northern provinces, are rising. HMPV symptoms include cough, congestion, fever, fatigue, and breathing difficulties; it can lead to bronchitis and pneumonia in vulnerable groups. There is no vaccine or specific antiviral treatment for HMPV; preventive measures like handwashing and avoiding contact are advised.

Notes:
India launched the Indian Biological Data Centre (IBDC) Portals, making 10,000 whole genome samples accessible globally. The data set enables advancements in genomics, personalized healthcare, and medicine. IBDC supports seamless access to genetic data, aiding researchers in studying genetic variations and developing precise genomic tools. The Framework for Exchange of Data Protocols (FeED) ensures ethical and secure genomic data sharing under Biotech-PRIDE Guidelines. The GenomeIndia project, led by Department of Biotechnology (DBT), creates a comprehensive genetic diversity database for cutting-edge research. India plans to sequence 10 million genomes, enhancing innovation in healthcare, agriculture, and biotechnology.

Notes:
Researchers developed the first nanobody-based inhibitors targeting the Ebola virus. Ebola is caused by ortho ebola viruses, discovered in 1976 in the Congo, primarily found in sub-Saharan Africa. The virus gets its name from the Ebola River in Congo. Fruit bats are natural hosts, and it spreads through contact with infected animals or humans. Symptoms include fever, diarrhea, vomiting, bleeding, and often death. The average fatality rate is around 50%. There is no cure exists for Ebola. Experimental treatments like monoclonal antibodies have been used. Treatment focuses on fluid balance, blood plasma, and early intervention for better recovery chances.

Notes:
Ukraine’s Security Service and Navy used a Neptune missile to strike an ammunition depot in Russia’s Rostov region. The R-360 Neptune is a Ukrainian-made subsonic cruise missile, originally designed for anti-ship use and later adapted for land attacks. It is based on the Russian Kh-35 missile, known as AS-20 Kayak by NATO. The missile entered service with the Ukrainian Navy in March 2021. It weighs 870 kg, is 5.05 meters long, and has a 400 km range. It travels at 900 km/h, with altitudes from 10 to 300 meters, dropping to 3 meters in the final phase.

Notes:
The Ministry of Electronics & Information Technology (MeitY) and Data Security Council of India (DSCI) launched the second edition of the Cyber Security Grand Challenge (CSGC 2.0). The prize pool has been increased to Rs. 6.85 crores from Rs. 3.2 crores. Innovators, startups, and entrepreneurs are invited to address six key cybersecurity challenges, including API Security, Data Security, and AI for Threat Detection. Intellectual property rights for solutions developed will stay with startups. The competition has four stages, with winners receiving Rs. 25 lakh, and the overall winner getting Rs. 1 crore. The initiative supports Digital India and Atmanirbhar Bharat.

Notes:
India becomes the fourth country to successfully achieve Space Docking Experiment (SpaDeX), after the US, Russia, and China. The technology allows two satellites to dock in space, enabling the assembly of larger modules and overcoming rocket payload limits. This technology is crucial for long-duration missions, Mars exploration, lunar sample return, and the planned Bharatiya Antariksh Station for resupply and crewed missions.

Notes:
Swiss researchers have developed a gene editing technique to potentially treat Stargardt disease, also known as Stargardt macular degeneration. This rare genetic eye condition causes progressive vision loss in children and young adults, usually bilateral, involving both eyes. The disease is characterized by excessive lipofuscin buildup over the macula, responsible for clear central vision. The disease is more common in males and affects 1 in 8000 to 10,000 populations. Currently, there is no cure for the disease.

Notes:
Paraquat, also called paraquat dichloride or methyl viologen, is a widely used herbicide. It controls weed growth and desiccates crops like cotton before harvest. The World Health Organization classifies it as a Category 2 chemical, meaning it is moderately hazardous and irritating. Paraquat is banned in over 70 countries, including China and the European Union, due to its high toxicity. Despite the bans, it is still widely used in the US and India. Recently, paraquat poisoning gained attention after being used in a high-profile murder case in Kerala.

Notes:
South Africa’s MeerKAT telescope discovered a new giant radio galaxy (GRG) named ‘Inkathazo,’ meaning ‘trouble’ in Xhosa and Zulu. The galaxy spans 3.3 million light-years, 32 times the size of the Milky Way, and is 1.44 billion light-years from Earth. GRGs are massive structures that emit jets of hot plasma powered by supermassive black holes. These jets glow at radio frequencies and stretch millions of light-years into space. Once considered rare, GRGs are now being discovered frequently due to advanced radio telescopes like MeerKAT in South Africa’s Northern Cape.

Notes:
Japan successfully launched the Michibiki 6 satellite on the new H3 rocket, aiming to improve its navigation system. The launch occurred at the Tanegashima Space Center, and the satellite separated successfully 29 minutes after liftoff. Michibiki 6 will be the fifth satellite in Japan’s quasi-zenith satellite system (QZSS). The system supplements US GPS and improves positioning for various devices. Japan plans to expand to seven satellites by 2026 and an 11-satellite network by the late 2030s. The launch was the fourth successful flight for the H3 rocket system.
