Science & Technology Current Affairs MCQs

Notes:
PathGennie is a novel computational framework developed by scientists at S. N. Bose National Centre for Basic Sciences, Kolkata (DST autonomous institute). Published in the Journal of Chemical Theory and Computation, it accelerates simulation of rare molecular events for computer-aided drug discovery (CADD). It focuses on predicting drug unbinding from protein targets without artificial biases used in classical methods. PathGennie uses direction-guided adaptive sampling, launching many ultrashort unbiased MD trajectories and extending only productive ones (“survival of the fittest”).

Notes:
A new study suggests ulcerative colitis may be triggered when a normally hidden protective layer of immune cells beneath the gut lining becomes thinner. Ulcerative colitis (UC) is a chronic inflammatory bowel disease (IBD) affecting the colon and rectum. It causes long-term inflammation and ulcers in the inner lining of the large intestine. Ulcerative colitis (UC) is an immune-mediated condition with cycles of flare-ups and remission.

Notes:
India inaugurated the world’s second National Environmental Standard Laboratory (NESL) and the world’s fifth National Primary Standard Facility for Solar Cell Calibration at CSIR–National Physical Laboratory (NPL), New Delhi. NESL will provide India-specific calibration and certification of air pollution monitoring systems, supporting regulatory bodies, industries, and startups, and improving policy enforcement under programmes like the National Clean Air Programme (NCAP).

Notes:
Astronomers from Aryabhatta Research Institute of Observational Sciences studied the W Ursae Majoris (W UMa) star. They used data from Devasthal Fast Optical Telescope and NASA’s Transiting Exoplanet Survey Satellite (TESS). W UMa is a low-mass contact binary and an eclipsing binary variable star. The two stars share a single outer atmosphere and orbit each other. W UMa stars show light curves with nearly equal minima and continuous brightness variation. Studying W UMa helps determine stellar masses, radii, and temperatures, aiding understanding of stellar evolution.

Notes:
NASA’s Hubble Space Telescope discovered a new astronomical object named Cloud-9. Cloud-9 is a starless, gas-rich, dark-matter-dominated cloud, classified as a Reionization-Limited H I Cloud (RELHIC). It is located 14 million light-years from Earth, near the spiral galaxy Messier 94 (M94). The cloud is made of neutral hydrogen (H I) spanning about 4,900 light-years, with a mass approx 1 million times the Sun. Cloud-9’s dark matter mass is estimated at 5 billion solar masses. It is a relic of early galaxy formation, a “failed galaxy” that did not form stars.

Notes:
Artemis II is the first crewed mission of NASA’s Artemis programme and will mark humanity’s return to the Moon’s vicinity for the first time since 1972. The 10-day mission will test the Space Launch System (SLS) rocket and the Orion spacecraft to verify life-support, navigation, and safety systems for future lunar missions. On January 9, NASA announced that Artemis II had entered its final preparation phase. The fully assembled rocket is expected to be rolled out to Launch Pad 39B at the Kennedy Space Centre in mid-January for final testing.

Notes:
Recently, the CSIR Integrated Skill Initiative trained over 1.90 lakh individuals through more than 5,200 skill-based programmes. It is a flagship national programme of the Council of Scientific and Industrial Research (CSIR). It aims to bridge the gap between scientific research, industry needs, and employable skills. The initiative integrates skill development with science and technology using CSIR’s research infrastructure. It offers inclusive access to students, researchers, professionals, school dropouts, ITI diploma holders, farmers, and rural communities.

Notes:
A Guillain-Barré Syndrome (GBS) outbreak has been reported in Neemuch district of Madhya Pradesh, with two deaths in Manasa town. Guillain-Barré Syndrome is a rare neurological disorder in which the body’s immune system attacks the peripheral nervous system. The peripheral nervous system is the network of nerves outside the brain and spinal cord that controls movement, pain, and sensations. Since the immune system causes the damage, it is an autoimmune disease, also called acute inflammatory demyelinating polyradiculoneuropathy.

Notes:
Indian scientists from Centre for Nano and Soft Matter Sciences, Bengaluru under Department of Science and Technology (DST) developed a solar-powered energy storage device that captures and stores energy in a single unit. The device is known as a photo-rechargeable supercapacitor. Unlike conventional systems, it combines energy harvesting and storage, reducing cost, energy loss, system complexity, and footprint. It enables portable, wearable, off-grid applications, reduces reliance on fossil fuels and conventional batteries, and works in remote areas.

Notes:
The Indian National Centre for Ocean Information Services (INCOIS) will launch three new ocean services: Jellyfish Artificial Intelligence Information Platform (JellyAIIP), SAMUDRA 2.0 Mobile Application, and Seamless Information Visualization and Analysis System (SIVAS) along with a new logo. It was established as an autonomous body under the Ministry of Earth Sciences (MoES) and is located in Hyderabad, Telangana. It provides ocean information and advisory services through continuous ocean observations and focused research. It runs the Indian Tsunami Early Warning Centre (ITEWC), issuing tsunami alerts within 10 minutes for India and 28 Indian Ocean countries.
