Science & Technology Current Affairs MCQs

Notes:
Silver nanowire-based conductive ink technology was transferred to two startups at NIT Warangal. The startups are M/s Chematico Technologies Private Limited (incubated at IIT Ropar) and M/s Vasanthbala Functional Materials Pvt Ltd (incubated at NIT Warangal). The technology was developed under a project funded by the Ministry of Electronics and Information Technology (MeitY). It aims to reduce dependency on foreign countries and tap into the growing demand for advanced electronic materials. The ink is used in flexible electronics, wearable devices, solar panels, RFID tags, and more. The global market for this ink is expected to surpass $16.87B by 2032. India imports conductive ink worth $15,72,000 annually from countries like the US, China, and Taiwan.

Notes:
The ISRO mission that successfully germinated lobia seeds (also known as cowpea seeds) in space is called the “CROPS” experiment, which stands for “Compact Research Module for Orbital Plant Studies”. The seeds sprouted on the fourth day, with leaves visible by the fifth day, marking a major milestone in space research. The experiment aims to develop sustainable food sources for long-term space missions and test plant growth in microgravity and controlled environments. Success supports astronauts by enabling food growth, oxygen generation, and CO₂ recycling in space. It highlights India’s capability in managing complex life-support systems and contributes to global space farming initiatives.

Notes:
The Prime Minister praised Indian space startup Digantara for the success of its Mission SCOT. SCOT (Space Camera for Object Tracking) is Digantara’s first mission for space surveillance and one of the world’s first commercial Space Situational Awareness (SSA) satellites. It was launched aboard SpaceX’s Transporter-12 mission and deployed in a sun-synchronous orbit. SCOT is designed to track Resident Space Objects (RSOs) as small as 5 cm in Low Earth Orbit (LEO) with high accuracy and revisit rates. It addresses gaps in existing systems limited by fields of view, weather, and geography.

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:
Georgia has been certified malaria-free by the World Health Organization. It is located at the intersection of Eastern Europe and West Asia, in the Transcaucasia region. Malaria is a life-threatening fever caused by Plasmodium parasites spread by infected female Anopheles mosquitoes. It is primarily found in tropical countries and is not contagious. The disease cannot spread from person to person; transmission occurs through mosquito bites.

Notes:
A new research paper identifies Chronic Pulmonary Aspergillosis (CPA), a life-threatening fungal infection, mostly in tuberculosis survivors in Assam’s tea plantations. Chronic Pulmonary Aspergillosis (CPA) is caused by Aspergillus fumigatus, a fungus that infects individuals with weak immune systems. It commonly affects people with pre-existing lung damage, like from TB, and shares symptoms with TB. Symptoms include coughing up blood, weight loss, fatigue, shortness of breath, and wheezing. Treatment involves antifungal medication and sometimes surgery. Aspergillus fungi are widely found in soil, decaying plants, and grains, but only a few species pose a threat to humans.

Notes:
IIT-Madras researchers have extracted silicon carbide (SiC) from simulated moon soil, aiding future lunar habitat construction. Silicon carbide (SiC), also called carborundum, is a synthetic crystalline compound of silicon and carbon. It is extremely hard, has high thermal conductivity, and offers excellent resistance to wear, oxidation, and chemical reactions.

Notes:
ISRO successfully launched the navigation satellite NVS-02 on January 29 aboard GSLV-F15 from Satish Dhawan Space Centre (SDSC), Sriharikota. This was ISRO’s historic 100th launch, marking a major milestone. GSLV-F15 used an indigenous cryogenic stage to place the satellite in a Geosynchronous Transfer Orbit (GTO). This was the 17th flight of the GSLV series and the 11th using ISRO’s cryogenic engine. NVS-02 will replace IRNSS-1E and enhance India’s navigation capabilities.

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:
The partial failure of the NVS-02 satellite is a setback for India’s NavIC system. NavIC (Navigation with Indian Constellation) is India’s own satellite navigation system. It was previously known as the Indian Regional Navigation Satellite System (IRNSS). Developed by ISRO, it provides accurate positioning and navigation services over India and nearby regions. NavIC aims to reduce reliance on foreign navigation systems like GPS (USA), GLONASS (Russia), and Galileo (Europe). It supports both civilian and strategic applications for reliable and autonomous navigation.
