Science & Technology Current Affairs MCQs

Notes:
Kerala recently reported a new case of Nipah virus infection, highlighting the state’s renewed struggle with this rare and deadly zoonotic virus. The Nipah virus, according to the World Health Organization (WHO), is a newly emerging zoonosis, meaning it is transmitted from animals to humans. The virus primarily spreads through fruit bats and contaminated food, making it a significant public health threat. Nipah virus infection progresses rapidly, and there is no specific treatment available for it. The virus is known for its high fatality rate and the potential for human-to-human transmission.

Notes:
Researchers have recently found that magnetar flares can create heavy elements like gold using a process called rapid neutron-capture or r-process nucleosynthesis. Magnetars are a special type of neutron star with extremely powerful magnetic fields—about a thousand times stronger than normal neutron stars. These stars sometimes release huge flares of energy, and one such giant flare in 2004 helped scientists make this discovery. The flare was observed by NASA’s Compton Gamma Ray Observatory, which recorded strange gamma-ray signals nearly a day later. These delayed signals did not match typical afterglows but showed signs of radioactive decay from neutron-rich elements. This proves that r-process nucleosynthesis, earlier linked mainly to neutron star mergers, can also happen in magnetar flares. This recent evidence changes our understanding of where rare elements like gold in the universe might come from.

Notes:
A recent large-scale study from South Korea, published in the European Heart Journal, found that people vaccinated against shingles have a 23% lower risk of cardiovascular events like heart attacks and strokes. Shingles, or herpes zoster, is caused by the reactivation of the varicella-zoster virus, the same virus that causes chickenpox. The virus stays dormant in nerve cells and can reactivate later in life when the immune system weakens. Shingles appears as a painful rash with blisters, usually on one side of the body, and can cause symptoms like burning, headache, and fever. The most common complication is postherpetic neuralgia (PHN), a nerve pain that can last for months. Shingles is not directly contagious but the virus can infect someone who never had chickenpox. It mainly affects people over 50 or those with weak immune systems.

Notes:
China has launched 12 satellites to begin building the world’s first space-based supercomputing network, called the Three-Body Computing Constellation. The satellites were launched using a Long March 2D rocket from the Jiuquan Satellite Launch Centre as part of a project led by Zhejiang Lab. These satellites have Artificial Intelligence (AI)-powered processors and high-speed links to communicate and process data in orbit without ground stations. Once complete, the constellation will include 2,800 satellites with a combined power of 1,000 peta operations per second (POPS). The project is developed by ADA Space, Zhijiang Laboratory, and Neijang High-Tech Zone to offer real-time, autonomous data processing from space.

Notes:
Chinese scientists recently discovered a new species of bacteria named Niallia tiangongensis aboard the Tiangong Space Station. The Tiangong Space Station, meaning ‘Sky Palace’, is a Chinese-owned and permanently crewed space station in Low Earth Orbit (LEO). It is the final phase of China’s Manned Space Program, developed after earlier missions Tiangong-1 and Tiangong-2. The first module, Tianhe, was launched in April 2021 and connects two science modules, Wentian and Mengtian, with a planned space telescope called Xuntian.

Notes:
Recently, the Battery Aadhaar Initiative was launched under the Department of Science and Technology (DST) at the Battery Summit 2025. Tata Elxsi showcased a technology demonstrator of Battery Aadhaar using its MOBIUS+ platform, which acts as a Digital Product Passport for batteries. Each battery pack will get a unique digital identity under this initiative. This helps track manufacturing origin, battery chemistry, safety certifications, and lifecycle performance. It allows monitoring of key parameters like charge-discharge cycles, enabling predictive maintenance and efficient recycling. The initiative also aims to prevent counterfeit batteries, increase consumer trust, and promote a circular economy.

Notes:
Recently, three new startups were selected to build India’s own Foundation Model under the IndiaAI Mission, marking a big step in boosting local Artificial Intelligence (AI) capabilities. The IndiaAI Mission was launched in 2023 as a joint effort by the Ministry of Electronics and Information Technology (MeitY) and the National Association of Software and Service Companies (NASSCOM). It supports startups and researchers by providing access to high-end computing power. The mission promotes “Making AI in India” by developing AI technologies locally.

Notes:
Recently, two Chinese nationals were charged in the United States for allegedly smuggling Fusarium graminearum, an agricultural pathogen, into the country. Fusarium graminearum is an ascomycete fungus that causes Fusarium Head Blight (FHB), which affects crops like wheat, maize, barley, oats, and rice. It produces a toxin called Vomitoxin or Deoxynivalenol, which is harmful to both humans and animals. This fungus reduces crop yield and quality while contaminating grains with toxic mycotoxins. This incident raises concerns about agro-terrorism, which is the deliberate use of plant pathogens or pests to attack agriculture and create economic loss, food insecurity, and public fear.

Notes:
Researchers from the Indian Institute of Science Education and Research (IISER), Bhopal, found that a protein called BBX32 helps plants grow properly from darkness into light. BBX32 is a B-box (BBX) protein that plays a key role in plant growth and development. It helps control when a seedling starts growing above soil, improving chances of healthy growth. This discovery helps understand how seedlings grow and could help improve crop establishment in agriculture.

Notes:
A new study highlights that dogs may help detect the early spread of Valley Fever, offering a new tool for public health. Valley Fever, or acute coccidioidomycosis, is a fungal infection caused by Coccidioides organisms found in soil. The fungi are common in the Pacific Northwest, southwestern United States, Mexico, Central America, and South America. The infection spreads when soil is disturbed and people or animals breathe in the fungal spores. Symptoms may be absent or resemble flu or pneumonia, and appear 5 to 21 days after exposure.
