Science & Technology Current Affairs MCQs

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:
The Central Government has mandated petrol pumps to supply E20 fuel with a minimum octane rating of 95 RON to promote cleaner and more efficient fuel usage. E20 fuel is a blended fuel consisting of 20% ethanol and 80% petrol, aimed at reducing dependence on fossil fuels. Ethanol used in E20 is a biofuel derived from renewable crops such as sugarcane, maize, and grains, making it environmentally sustainable. E20 fuel has a higher octane rating (minimum 95 RON) compared to regular petrol in India, which typically has an octane rating of 91–92 RON.

Notes:
Newcastle Disease is a highly contagious viral disease affecting poultry and wild birds, recently reported spreading across Europe and the United Kingdom (UK). It is caused by Avian Paramyxovirus Serotype 1 (APMV-1) and has global distribution. It occurs in three forms: lentogenic (mild), mesogenic (moderate), and velogenic (highly virulent). Transmission occurs via respiratory droplets, exhaled air, and feces of infected birds. Symptoms include respiratory distress (gasping, coughing), nervous signs (paralysis, twisted neck), and diarrhoea.

Notes:
The Pentagon’s Project Maven AI program was launched by the United States in 2017. The program was launched by the United States in 2017. It uses machine learning and computer vision to automatically detect objects, movements, and patterns, reducing the need for manual analysis. The programme helps in real-time identification and tracking of targets, improving the speed and accuracy of military operations.

Notes:
India has successfully demonstrated a 1,000-kilometre quantum communication network under the National Quantum Mission, a major breakthrough in secure communication technologies. The National Quantum Mission (NQM) was launched by the Department of Science & Technology with an outlay of Rs.6003 crore for 2023-24 to 2030-31. Its objective is to seed, nurture, and scale up scientific and industrial research and development (R&D) and create an innovative ecosystem in Quantum Technology (QT). It is one of nine initiatives under the Prime Minister’s Science Technology Innovation Advisory Council (PM-STIAC).

Notes:
Researchers from the University of Cambridge have developed a hafnium-oxide memristor, a brain-inspired nanodevice that can significantly reduce Artificial Intelligence (AI) energy consumption. A memristor (memory + resistor) is an electronic component whose resistance depends on past current flow, enabling it to “remember” previous electrical states. Unlike a conventional resistor, a memristor has variable resistance and retains its state even when the current is switched off. Memristors are nanoscale devices with low energy requirements and are commonly made using materials like titanium dioxide (TiO₂) between metal electrodes.

Notes:
Scientists from Centre for Nano and Soft Matter Sciences, Bengaluru, developed a smart material that can both store energy and indicate charge level through colour change. The material is an oxygen-deficient bimetallic oxide made of molybdenum and tungsten. It appears blue when charged and transparent when discharged, enabling real-time visual monitoring. The innovation uses oxygen vacancies to enhance ion movement and alter electronic structure. It was synthesised using the solvothermal method.

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:
A suspected outbreak of hantavirus on a Netherlands-based cruise ship has caused deaths and illnesses. Hantavirus is a rodent-borne virus transmitted to humans through inhalation of airborne particles from rodent droppings, saliva, or urine. It causes two major diseases: Hantavirus Pulmonary Syndrome (HPS), affecting the lungs, and Haemorrhagic Fever with Renal Syndrome (HFRS), affecting the kidneys. Symptoms begin with flu-like signs such as fever and fatigue, followed by respiratory distress after a few days. There is no specific treatment, and management mainly involves supportive care such as rest and fluids.

Notes:
India recently launched Donanemab, the country’s first therapy for Alzheimer’s disease. Alzheimer’s disease is a progressive brain disorder and the most common cause of dementia. Dementia involves decline in memory, thinking ability, and behaviour that affects daily life. The disease is associated with ageing, genetics, and lifestyle-related factors.
