Science & Technology Current Affairs MCQs

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:
According to the Centers for Disease Control and Prevention (CDC), autism now affects 1 in 31 children in the United States as of 2022, up from 1 in 36 in 2020. Autism Spectrum Disorder (ASD) is a neurodevelopmental condition that affects brain development, causing challenges in communication, social skills, behaviour, and learning. Symptoms usually appear before age 3, but diagnosis may be delayed due to low awareness. Individuals with ASD may show repetitive actions, limited interests, and unique learning or movement styles. ASD results from both genetic and environmental factors, with genetics playing a major role. No evidence links vaccines to autism, and such claims are false and harmful.

Notes:
On May 23, 2025, Chennai-based startup Agnikul Cosmos successfully test-fired India’s first electric motor-driven semi-cryogenic engine. This marks a major step for private players in advancing Indian space technology. The engine uses electric motors instead of traditional gas generators to power fuel pumps, allowing precise thrust control and quick response. It runs on semi-cryogenic propulsion using liquid oxygen (LOX) and refined kerosene, balancing performance and cost. This innovation boosts engine reliability and suits future sub-orbital missions.

Notes:
Recently, the Union Health Ministry announced plans to integrate India’s Rare Donor Registry with the national online blood management platform called e-Rakt Kosh. e-Rakt Kosh is an online blood bank management system implemented under the National Health Mission. It is the official portal for all blood-related services in India. It provides real-time information on blood availability, blood banks, and donation camps across the country.

Notes:
Recently, the Ministry of Science and Technology announced that researchers at the Institute of Nanoscience and Technology (INST), Mohali, have developed a smart water filter using sunlight, gentle vibrations, and Artificial Intelligence (AI). The innovation addresses pollution caused by industrial wastewater containing harmful dyes like Methylene Blue and Congo Red, which threaten human health and ecosystems. This method ensures continuous purification, even on cloudy days, making it a smart alternative to traditional solar-powered filters.

Notes:
Recently, India’s Group Captain Shubhanshu Shukla made history by piloting the Axiom-4 mission aboard SpaceX’s Dragon capsule from Kennedy Space Center, Florida. He became the first Indian in 41 years to cross the Kármán line after Rakesh Sharma’s spaceflight in 1984. Prime Minister Narendra Modi congratulated Shukla and called him the first Indian en route to the International Space Station (ISS). This marks a major milestone for India in human spaceflight and international space collaboration.

Notes:
Recently, Novo Nordisk launched its weight-loss injection semaglutide in India after Eli Lilly introduced tirzepatide. These are Glucagon-Like Peptide-1 (GLP-1) receptor agonists, which are drugs that copy the action of GLP-1, a gut hormone released after eating. GLP-1 helps control blood sugar, fat metabolism, and appetite in the body. These medicines usually come as injections, though oral forms are being developed. Semaglutide and tirzepatide are two leading GLP-1 Drugs. Semaglutide and tirzepatide transforming the treatment of obesity and diabetes in India.

Notes:
Recently, the Chief Minister of Karnataka asked the Horticulture Department for a report on the threat of black-headed caterpillar (Opisina arenosella) disease harming coconut plantations. This pest damages coconut trees in both coastal and inland areas by eating leaf green parts from silken galleries, lowering photosynthesis. It attacks coconuts of all ages, leaving dried patches on lower leaves while only a few young leaves stay green. The pest spreads quickly by wind and peaks in summer.

Notes:
Recently, in the ‘Mann Ki Baat’ programme, the Prime Minister of India announced that India has been declared free of Trachoma, a bacterial eye disease. Trachoma is caused by the bacterium Chlamydia trachomatis and spreads through contact with the eyes, eyelids, or throat secretions of infected people. The World Health Organization (WHO) calls it a neglected tropical disease, affecting around 150 million people worldwide. In 2017, India was declared free from infective Trachoma, with surveillance continuing until 2024.

Notes:
The United Kingdom has officially launched the Synthetic Human Genome Project, a groundbreaking effort to build human DNA from scratch. This project shifts from reading DNA, like in the Human Genome Project, to writing and assembling it synthetically. Scientists aim to create disease-resistant cells to repair damaged organs such as the heart, liver, and immune system. It could help treat genetic and age-related diseases by studying how genes control repair and development.
Critics warn about ethical concerns like designer humans and synthetic life.
