Science & Technology Current Affairs MCQs

Notes:
Recently, Japan successfully launched a climate monitoring satellite on its H-2A rocket, which made its final flight before retiring. The H-2A lifted off from Tanegashima Space Center carrying the Global Observing Satellite for Greenhouse gases and Water cycle (GOSAT-GW) to track carbon, methane, and water cycles. The launch faced delays due to electrical issues but succeeded, marking the 50th mission of H-2A since 2001 with a 98% success rate. GOSAT-GW will soon share high-resolution data globally, including with the United States National Oceanic and Atmospheric Administration (NOAA).

Notes:
Recently, comet 3I/ATLAS from outside our solar system was spotted by the Asteroid Terrestrial-impact Last Alert System (ATLAS) in Chile. ATLAS is an asteroid impact early warning system developed by the University of Hawaii and funded by the National Aeronautics and Space Administration (NASA). It uses four telescopes — two in Hawaii, one in Chile, and one in South Africa. These telescopes scan the sky every night for moving objects. ATLAS also detects dwarf planets, supernova explosions, and light from stars eaten by supermassive black holes.

Notes:
The world’s first-ever malaria treatment suitable for babies and very young children has been approved for use. Drug manufacturer Novartis has received approval from Swiss authorities for its new malaria drug named Coartem. The development of the drug is very significant, as the overwhelming majority of malaria-related deaths occur in the under-five age group. Most malaria-related deaths are recorded on the African continent. Malaria accounted for more than half a million deaths worldwide in 2023.

Notes:
Recently, Microsoft introduced BioEmu, an advanced Artificial Intelligence (AI) system for simulating protein motion to accelerate drug discovery. The system is officially named Biomolecular Emulator-1 (BioEmu-1). BioEmu-1 is a deep learning model that can generate thousands of protein structures per hour using a single Graphics Processing Unit (GPU). Proteins are vital for biological processes like muscle formation and disease protection. Earlier, predicting protein structures from amino acid sequences was difficult. BioEmu-1 offers deeper insights into protein behavior, which is crucial for developing effective medicines.

Notes:
In July 2025, five confirmed cases of Legionnaires’ disease were reported in Central Harlem, New York City. The New York City Department of Health launched an urgent investigation into possible environmental sources. Cooling towers, air conditioners, hot tubs, and humidifiers are being tested for Legionella bacteria. Legionnaires’ disease is a severe type of pneumonia caused by Legionella bacteria. The bacteria are found in natural water sources like lakes, rivers, and soil, and can spread through inhaling contaminated water droplets. It is not contagious and cannot spread from person to person.

Notes:
Recently, African Swine Fever (ASF) outbreak was confirmed at a pig farm in Ravas Brahmanan village, Patiala, Punjab. District authorities have taken immediate action to contain the spread. African Swine Fever (ASF) is a highly contagious viral disease affecting domestic pigs and wild boars. It does not affect humans or other animal species. It causes high mortality (up to 90–100%) and severely impacts pig farming. It originated in sub-Saharan Africa and has spread to Europe, Asia, and Africa. In India, it was first detected in Arunachal Pradesh and Assam in Feb–Mar 2020.

Notes:
Recently, a new blood group named CRIB was discovered in a South Indian woman from Kolar district, Karnataka. The discovery was announced at the 35th Regional Congress of the International Society of Blood Transfusion (ISBT) held in Milan, Italy. CRIB stands for Cromer India Bangalore and is part of the Cromer (CR) blood group system. This blood group was previously unidentified anywhere in the world. The discovery took 10 months of research and molecular testing by international experts.

Notes:
Recently, reports claim the Trump administration asked NASA to shut down Orbiting Carbon Observatories (OCO). The Orbiting Carbon Observatory (OCO) Program, managed by NASA’s Jet Propulsion Laboratory (JPL), is an initiative of NASA. OCO are Earth remote sensing satellites designed to monitor atmospheric carbon dioxide (CO₂) from space to understand climate change.

Notes:
On 15 August 2025, Chinese commercial aerospace company Geespace successfully completed the fourth orbital deployment of GEESATCOM (Geely Constellation) by launching 11 satellites from waters off Rizhao, Shandong Province aboard a single rocket. All satellites entered their planned 600 km orbits and are operating normally. GEESATCOM, independently developed and operated by Geespace, supports satellite Internet of Things (IoT) testing and inter-satellite communications. It also provides Earth observation for ecological and environmental monitoring.

Notes:
Two Indian aquanauts recently conducted deep-sea dives in the Atlantic Ocean under Samudrayaan Project. They collected over 100 kg of cobalt-rich polymetallic nodules from 1,173 meters depth in the Andaman Sea. Deep Ocean Mission was launched by Ministry of Earth Sciences (MoES) on 7 September 2021 with ₹4,077 crore for 5 years. The mission develops technologies for exploring and using deep ocean resources sustainably. It supports India’s Blue Economy with potential to push maritime economy beyond ₹100 billion. It aligns with United Nations Decade of Ocean Science (2021–2030).
