Science & Technology Current Affairs MCQs

Notes:
Researchers at the Indian Institute of Science (IISc), Bengaluru, recently developed a metal-based nanozyme to help control abnormal blood clotting caused by Pulmonary Thromboembolism (PTE). Pulmonary Thromboembolism is a condition where blood clots block arteries in the lungs, which can be life-threatening. Nanozymes are nanomaterials that act like enzymes and can be made from metals, metal oxides, or carbon-based substances. This new nanozyme could offer a promising treatment option by safely breaking down harmful clots.

Notes:
Tourette Syndrome is a neurological disorder that causes sudden, involuntary movements or vocal sounds called tics. It usually starts between the ages of 2 and 15, with the average age of onset around six. It affects around 0.3% to 1% of the global population, as highlighted in recent reports. The condition is more common in boys than in girls. Tics can be mild or severe and may include blinking, jerking, or making sounds. In severe cases, it can impact speech, daily activities, and overall quality of life.

Notes:
The Centre for Development of Telematics (C-DOT) recently launched the ‘Samarth’ Incubation Program to support startups in the Telecom and Information and Communication Technology (ICT) sector. C-DOT is an autonomous telecom research and development institution under the Department of Telecommunications (DoT), Government of India. The program offers financial grants, advanced technical resources, and expert guidance to help startups grow from idea stage to commercial success. It focuses on building sustainable and scalable business models.

Notes:
China has launched the Zhangheng 1B satellite to strengthen early warning systems for natural disasters by monitoring Earth’s electromagnetic environment. It was launched aboard a Long March 2D rocket from the Jiuquan Satellite Launch Center in the Gobi Desert. Developed in partnership with Italy under a 2019 cooperation agreement, the satellite entered orbit as planned. Zhangheng 1B is China’s first satellite focused on studying geophysical fields from space and will work with Zhangheng 1A launched in 2018. It carries nine instruments, including an electric field detector and a high-energy particle sensor built by Italy.

Notes:
Recently, the Union Health Ministry announced plans to integrate India’s Rare Donor Registry with the national online blood management platform called e-Rakt Kosh. e-Rakt Kosh is an online blood bank management system implemented under the National Health Mission. It is the official portal for all blood-related services in India. It provides real-time information on blood availability, blood banks, and donation camps across the country.

Notes:
Recently, India’s Jahnavi Dangeti was announced as the first Indian astronaut to join the Titans Space mission scheduled for 2029. She is a graduate of the National Aeronautics and Space Administration (NASA)’s International Air and Space Program and has received global training. Jahnavi is also a strong promoter of STEM (Science, Technology, Engineering, and Mathematics) education among youth. The mission will be led by retired U.S. Army Colonel and veteran NASA astronaut William McArthur Jr., who is now Chief Astronaut at Titans Space.

Notes:
Recently, the Ministry of Science and Technology announced that researchers at the Institute of Nanoscience and Technology (INST), Mohali, have developed a smart water filter using sunlight, gentle vibrations, and Artificial Intelligence (AI). The innovation addresses pollution caused by industrial wastewater containing harmful dyes like Methylene Blue and Congo Red, which threaten human health and ecosystems. This method ensures continuous purification, even on cloudy days, making it a smart alternative to traditional solar-powered filters.

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:
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, an eight-week study in Brazil found that Kombucha improves gut bacteria in people with obesity by increasing good microbes and reducing harmful ones. However, it did not improve blood sugar or inflammation markers. Kombucha is a fermented tea that offers complex flavors without much sugar or caffeine. It originated in northeast China around 220 BCE and was known for its energizing and detoxifying effects. Kombucha is becoming popular in India, with the market growing from $45 million in 2020 to $102 million in 2024.
