Science & Technology Current Affairs MCQs

Notes:
IIT Madras has launched the AMOLED Research Centre (ARC) to develop next-generation AMOLED displays for smartphones, tablets, watches, and wearables. It is a National Centre of Excellence funded by MeitY, DRDO, and Tata Sons. AMOLED stands for Active-Matrix Organic Light-Emitting Diode. The initiative supports India’s goal of establishing a display manufacturing industry. The Centre includes researchers from diverse fields and features a state-of-the-art cleanroom with advanced fabrication and characterization equipment.

Notes:
Manastu Space, a start-up from IIT Bombay, successfully tested its green propulsion system, VYOM 2U. This environmentally friendly technology represents a significant advancement in satellite propulsion, offering a safer alternative to conventional toxic propellants. The test was conducted aboard ISRO’s PSLV C60 as part of the POEM-4 initiative, which provides a platform for innovative space experiments. The successful test marks a key milestone in the commercialization of sustainable propulsion technology for future space missions.

Notes:
Tularemia, also called ‘rabbit fever,’ has risen by over 50% in the US recently. It is a rare but potentially deadly infectious disease. It primarily affects children aged 5-9, older men, and American Indians or Alaska Natives. Tularemia is caused by the bacterium Francisella tularensis, which can infect various animals, especially rabbits and rodents. The disease is transmitted to humans through tick bites, contact with infected animals, or contaminated water. Symptoms can range from skin ulcers to severe respiratory issues.

Notes:
Researchers introduced Twigstats, a tool for time-stratified ancestry analysis, in a Nature study. Twigstats significantly enhances statistical power and reduces errors in ancestry studies. It provides high-resolution, precise individual-level ancestry analysis. The tool is coded in C++ and uses the statistical language R. Twigstats enables fine-grained analysis of specific historical periods.

Notes:
Centre for Development of Telematics (C-DOT) and IIT Delhi signed an agreement to develop THz communication front ends for 6G under the Telecom Technology Development Fund (TTDF). TTDF is established under the Universal Services Obligation Fund (USOF), now called Digital Bharat Nidhi, by the Department of Telecom. The fund supports research, design, prototyping, testing, and manufacturing in telecommunications. It aims to foster rural-specific communication technologies, promote technology ownership, and encourage indigenous manufacturing. TTDF seeks to boost exports, reduce imports, enhance co-innovation, and support Intellectual Property creation in the telecom sector.

Notes:
New research reveals that genetic mutations in Huntington’s Disease (HD) can have delayed effects, impacting disease progression over time. Huntington’s Disease (HD) is a genetic condition causing gradual loss of brain cell function, leading to their death. It affects brain regions regulating voluntary movement, memory, and decision-making, primarily the basal ganglia and brain cortex. HD is caused by a mutation in the HTT gene, which produces huntingtin protein crucial for neuron function. Mutated huntingtin proteins have abnormal shapes, damaging and killing neurons. HD is inherited; each child of an affected parent has a 50% chance of developing the disease. It affects 3 to 7 out of 100,000 people, primarily of European ancestry.

Notes:
The Pralay missile, India’s first tactical quasi-ballistic missile, will be showcased in the Republic Day parade. It is a short-range surface-to-surface ballistic missile with a range of 150-500 km, developed to meet the Army’s tactical needs. Pralay can carry a 350-700 kg conventional warhead and strike enemy positions with high accuracy. It was developed by DRDO.

Notes:
Niger has become the first African country to eliminate onchocerciasis, or river blindness. It joins Colombia, Ecuador, Mexico, and Guatemala as WHO-verified onchocerciasis-free nations. Onchocerciasis is a parasitic disease affecting the eyes and skin, causing severe disability. It leads to disfiguring skin conditions, vision loss, and permanent blindness in severe cases. The disease has severely impacted livelihoods for decades. Over 99% of cases still occur in 31 African countries.

Notes:
OpenAI launched a new AI tool called Deep Research on February 2. It is the first major release after the DeepSeek controversy. Deep Research gathers information from the internet and creates reports like a research analyst. OpenAI showcased its capabilities in a YouTube demonstration video. The tool was also privately presented to US lawmakers and government officials in Washington, DC.

Notes:
Ranikhet disease has caused the death of 1.5 lakh chickens in Andhra Pradesh. It is a contagious viral disease affecting poultry like chickens, turkeys, and ducks. It is caused by Newcastle disease virus (NDV) or avian paramyxovirus-1 (APMV-1). The disease attacks birds’ respiratory, nervous, and digestive systems. It leads to production drops and fertility issues in birds. Morbidity is high, and mortality ranges from 50 to 100%. It is a minor zoonosis, potentially causing mild conjunctivitis in humans, but usually self-limiting.
