Science & Technology Current Affairs MCQs

Notes:
Scientists discovered that metal lumps, called polymetallic nodules, on the dark seabed produce oxygen. Dark oxygen is created without sunlight or photosynthesis, which was previously thought to be the only way oxygen is produced. The oxygen comes from electrochemical activity in the nodules, not plants. Polymetallic nodules, made of metals like manganese, iron, cobalt, nickel, copper, and lithium, split H2O molecules into hydrogen and oxygen. This discovery challenges previous understanding and opens up new avenues for studying deep ocean processes and oxygen production at extreme depths.

Notes:
The Central Drugs Standard Control Organisation (CDSCO) has approved Qartemi, a second “living drug,” which is a Chimeric Antigen Receptor (CAR) T-cell therapy designed to treat blood cancer. “Living drugs” involve modifying a patient’s cells and reintroducing them into the body. CAR T-cell therapy is an innovative immunotherapy where T-cells are genetically engineered to target cancer cells. T-cells are extracted from the patient’s blood, modified in the lab by adding a gene for a man-made receptor (CAR), which helps T-cells recognize cancer cells. Modified CAR-T cells are then reintroduced to kill cancer cells.

Notes:
Researchers using NASA’s James Webb Space Telescope and Chandra X-ray Observatory discovered an unusual black hole that might illuminate the development of supermassive black holes. Chandra X-ray Observatory is NASA’s most powerful X-ray telescope, offering eight times greater resolution and detecting sources over 20 times fainter than its previous X-ray telescope. It was launched on July 23, 1999. It is designed to detect X-ray emissions from extremely hot areas in the Universe, including exploded stars, galaxy clusters, and matter near black holes.

Notes:
The International Solar Conference celebrated the 125th anniversary of the Kodaikanal Solar Observatory. The observatory, established in 1899, is currently owned and operated by the Indian Institute of Astrophysics. It is located in Kodaikanal, Tamil Nadu, in the Palani range of hills, chosen for its proximity to the equator and dust-free high-altitude setting. The observatory’s objective is to gather data on how the sun affects Earth’s atmosphere and to better understand monsoon patterns.

Notes:
The Centre for Nano and Soft Matter Sciences (CeNS) in Bengaluru, India developed the high-entropy alloy (HEA) catalyst for hydrogen production. CeNS is an autonomous institute of the Department of Science and Technology (DST). The catalyst is made of platinum, palladium, cobalt, nickel, and manganese (PtPdCoNiMn). The catalyst was prepared using two methods: electrodeposition and solvothermal processes.  The catalyst is more efficient than pure platinum and uses seven times less platinum than commercial catalysts.  The catalyst is stable and efficient for over 100 hours in alkaline seawater.

Notes:
Astronomers discovered Gaia BH3, a massive black hole close to Earth, using the European Space Agency’s (ESA) Gaia telescope. Gaia Mission, launched in 2013, aims to create the most precise 3D map of the Milky Way, surveying 1% of its 100 billion stars. It orbits the Sun at Lagrange Point 2 (1.5 million km from Earth), avoiding atmospheric distortion. Gaia scans the sky every two months using two telescopes. It helps detect exoplanets, main belt asteroids, and Near-Earth Objects (NEOs) by tracking stellar movements and brightness changes.

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:
Russia is reportedly starting large-scale production of Iskander-M tactical ballistic missiles. The Iskander (SS-26 Stone) is a road-mobile short-range ballistic missile system, first used in 2008 against Georgia. It is developed by Russia. It is designed for tactical strikes on small, high-value land targets. The missile is 7.3 meters long, weighs 3,750 kg, and has a 500 km range with a payload of 480-700 kg. It can carry conventional or nuclear warheads, travel at Mach 7, and reach over 30 miles in altitude. Equipped with decoys, maneuverable reentry, and self-targeting to bypass defense systems.

Notes:
The Blue Ghost Lander is developed by Firefly Aerospace for lunar exploration. It will deliver scientific payloads to the Moon under NASA’s Artemis Program. The lander supports NASA’s Lunar Surface Operations Program for sustainable human exploration. It marks a significant step in private sector involvement in space missions. The mission aims to advance lunar research and exploration efforts.

Notes:
IIT Kanpur introduced an innovative solar dehydration technique to preserve agricultural produce using solar energy. This method helps farmers dry fruits and vegetables, providing a cost-effective way to store produce and sell at better prices. The project is supported by NABARD. It aims to expand to more villages, reducing waste and increasing farmers’ incomes.
