Science & Technology Current Affairs MCQs

Notes:
Recently, India’s first agentic Artificial Intelligence (AI) named Kruti was launched by the startup Krutrim. It is a next-generation Generative AI (GenAI) tool that goes beyond just providing information. Kruti can act independently to manage complex tasks, make decisions, and solve problems for users and organizations. It uses advanced reasoning and step-by-step planning to handle multi-layered challenges without constant human input. It processes large amounts of data from various sources to create strategies and complete tasks on its own.

Notes:
Researchers have recently introduced a new term called “Thirstwaves” to describe long periods of high atmospheric thirst. A Thirstwave occurs when the daily evaporative demand stays above the historical 90th percentile for at least three consecutive days. Evaporative demand means how thirsty the atmosphere is or how much water it wants to absorb from the ground or plants. It is influenced by temperature, wind speed, humidity, and sunshine. Understanding thirstwaves can help farmers manage water more efficiently and boost crop production. This concept is important for improving climate resilience in agriculture and water planning.

Notes:
Recently, the National Institute of Immunohaematology developed an affordable and simple point-of-care test kit in India for early diagnosis of genetic bleeding disorders like Haemophilia A and Von Willebrand Disease. Haemophilia A is a hereditary bleeding disorder where blood does not clot properly due to low levels of Factor VIII, a key clotting protein.
Normally, when bleeding occurs, a process called the coagulation cascade activates clotting factors to stop the bleeding. If one or more of these clotting factors are missing or not working properly, it leads to excessive bleeding.

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, scientists at the Indian Institute of Science developed a glowing paper sensor to detect liver cancer. The sensor uses the green glow of Terbium to identify the enzyme beta-glucuronidase, which is a key biomarker for liver cancer. Terbium is a rare-earth metal belonging to the lanthanide series of the periodic table. It appears as a soft, silvery metal. Terbium is recovered from minerals like monazite and bastnaesite, and also from euxenite containing more than 1% terbium. It is used in solid-state devices and low-energy lightbulbs.

Notes:
Recently, the World Health Organization (WHO) launched the “3 by 35” Initiative to tackle non-communicable diseases (NCDs). It urges countries to raise taxes on tobacco, alcohol, and sugary drinks to achieve at least a 50% real price increase by 2035. NCDs like heart disease, cancer, and diabetes cause over 75% of global deaths. Higher taxes could prevent 50 million premature deaths over 50 years and generate USD 1 trillion in public revenue in the next decade. Between 2012 and 2022, around 140 countries already raised tobacco taxes, showing large-scale change is achievable.

Notes:
The Indian Institute of Science (IISc), Bengaluru, recently launched the BHARAT study under its Longevity India Program. BHARAT stands for Biomarkers of Healthy Aging, Resilience, Adversity, and Transitions. The study aims to map physiological, molecular, and environmental indicators that drive ageing in Indians. It will build India’s first comprehensive ageing database. It includes multiparametric analysis, advanced clinical assessment, and lifestyle factors. It will identify biomarkers for healthy ageing and set the Bharat Baseline for normal health values in India.

Notes:
Recently, Indian astronaut Shubhanshu Shukla interacted with students from the International Space Station (ISS) using ham radio. Ham radio, also called amateur radio, is a licensed radio service using radio waves for communication. It is used for education, knowledge sharing, and emergency or SOS communication. It needs a transceiver, antenna, and dedicated frequency operated by licensed ham operators. Communication can be local, global, or in space. In India, anyone above 12 years can use ham radio with a licence from the Ministry of Electronics and Information Technology.

Notes:
Researchers at Indian Institute of Space Science and Technology (IIST), Thiruvananthapuram recently detected circularly polarised radio emission near a young protostar about 4,500 light-years away. A protostar is the earliest stage in star formation, formed from a collapsing giant molecular cloud in the interstellar medium. As the cloud collapses, gravitational energy turns into heat, warming the forming protostar. The protostar stage lasts from 100,000 to 10 million years depending on the star’s mass. It begins with a dense molecular cloud core and ends with a pre-main-sequence star.

Notes:
The Indian Council of Medical Research (ICMR) is developing a new malaria vaccine called AdFalciVax to fight Plasmodium falciparum. This was recently highlighted due to its unique chimeric and recombinant design. AdFalciVax is being developed with Regional Medical Research Centre Bhubaneswar (RMRCBB), National Institute of Malaria Research (NIMR), and Department of Biotechnology – National Institute of Immunology (DBT-NII). It uses Lactococcus lactis, a safe food-grade bacterium, for production. The vaccine targets both the pre-erythrocytic and sexual stages of the malaria parasite. This dual-target approach offers both personal protection and reduction of mosquito transmission.
