Science & Technology Current Affairs MCQs

Notes:
Recently, Google DeepMind launched a new Artificial Intelligence model called AlphaGenome. AlphaGenome aims to predict accurately how individual mutations in human Deoxyribonucleic Acid (DNA) affect their functions and impact human health. It is built on DeepMind’s earlier genomics model named Enformer and works alongside AlphaMissense, which focuses on classifying the effects of variants in protein-coding regions. The model can analyze very long DNA sequences up to one million base pairs and generate highly detailed predictions.

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:
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.

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:
In July 2025, the Ministry of Information and Broadcasting launched the “Kalaa Setu – Real-Time Language Tech for Bharat” Challenge. It was introduced through the WaveX Startup Accelerator Platform to promote Artificial Intelligence (AI) for inclusive communication. The challenge invites top AI startups to create scalable tools that convert text into audio, video, and graphic content. These tools must support multiple Indian languages for real-time information delivery. The goal is to help government bodies communicate using regionally relevant formats like infographics, video explainers, and audio capsules.

Notes:
Recently, U.S. President Donald Trump cited the fentanyl crisis to justify imposing 35% tariffs on Canada. Fentanyl caused over 112,000 overdose deaths in the United States in 2024 alone. Fentanyl is a powerful synthetic opioid used medically as a pain reliever and anaesthetic. It is about 100 times stronger than morphine and 50 times stronger than heroin. Common street names include Apache, China Girl, China Town, Dance Fever, Goodfellas, Jackpot, and King Ivory. Fentanyl overdose can cause cold skin, bluish lips (cyanosis), coma, respiratory failure, and death.

Notes:
Former U.S. President Donald Trump was recently diagnosed with Chronic Venous Insufficiency (CVI). CVI is a condition where leg veins cannot efficiently return blood to the heart, causing blood to pool in the legs. Normally, vein valves help blood flow upward, but in CVI, these valves don’t function properly. It can lead to symptoms like leg pain, swelling, cramps, skin changes, varicose veins, and leg ulcers. CVI is more common in people who are overweight, pregnant, have a family history, or had leg injuries, surgery, or blood clots.

Notes:
A team at National Institute of Technology (NIT) Calicut has recently developed a low-cost, highly sensitive point-of-care device for early detection of sepsis. The device uses an electrochemical biosensor to detect endotoxins, which are key biomarkers of infection from Gram-negative bacteria. Sepsis is a life-threatening condition that can cause organ failure, shock, and even death if not treated early. The device can detect Lipopolysaccharide (LPS), a toxic component of bacterial membranes, within 10 minutes using blood serum.

Notes:
Recently, ISRO is preparing to launch three navigation satellites for the Indian Regional Navigation Satellite System (IRNSS) by next year. Indian Regional Navigation Satellite System (IRNSS), also called Navigation with Indian Constellation (NavIC), is developed by Indian Space Research Organisation (ISRO). It is an independent and fully indigenous satellite navigation system, under India’s full control. Indian Regional Navigation Satellite System (IRNSS) was designed as a 7-satellite constellation to cover India and 1,500 km around it.
