Science & Technology Current Affairs MCQs

Notes:
A recent study by the Global Antibiotic Research and Development Partnership (GARDP) showed that many multidrug-resistant infections in low- and middle-income countries, including India, are not being treated properly due to lack of access. GARDP is a not-for-profit organization that creates new antibiotic treatments for drug-resistant bacterial infections and ensures they reach people in need. It focuses on public health by developing antibiotics to fight the current antimicrobial resistance (AMR) crisis and protect future generations. GARDP was founded by the World Health Organization (WHO) and Drugs for Neglected Diseases initiative (DNDi) under the Global Action Plan on AMR in 2015.

Notes:
A new non-contact wearable device developed by researchers from the United States and South Korea can monitor health by measuring skin flux without touching the skin. The device is about the size of a smartphone and tracks molecular movements like vapour leaving the body and chemicals entering through the skin. It was developed under the leadership of Professor John A. Rogers at Northwestern University, USA. It creates a small sealed microclimate next to the skin and uses wireless electronics and tiny sensors to detect water vapour, carbon dioxide (CO₂), and volatile organic compounds (VOCs). A remote-controlled valve adjusts the chamber’s openness for accurate comparisons.

Notes:
A groundbreaking study has recently offered new hope for treating Lafora Disease, a rare and deadly genetic disorder. Lafora Disease seriously affects the brain and nervous system, leading to severe health issues. It is part of a group of disorders called autosomal recessive progressive myoclonus epilepsy (PME), which causes seizures, mental decline, and loss of motor skills. It is more common in areas where marriages between close relatives, called consanguineous marriages, are practiced. It is mainly seen in Mediterranean countries, Northern Africa, the Middle East, and parts of Southern India.

Notes:
NASA’s Gravity Recovery and Interior Laboratory (GRAIL) Mission recently created the most detailed gravity map of the Moon. The Gravity Recovery and Interior Laboratory (GRAIL) mission was launched by NASA. It was part of NASA’s Discovery Program. The new map will help build a precise lunar reference frame and time system, making future Moon missions safer and more accurate. The mission showed that the Moon’s nearside, which faces Earth, is warmer and more geologically active than the farside. Earth’s gravity pulls more on the nearside, causing it to flex more and revealing interior structural differences. The nearside has large flat plains called “mare”, while the farside has rugged terrain.

Notes:
A recent large-scale study from South Korea, published in the European Heart Journal, found that people vaccinated against shingles have a 23% lower risk of cardiovascular events like heart attacks and strokes. Shingles, or herpes zoster, is caused by the reactivation of the varicella-zoster virus, the same virus that causes chickenpox. The virus stays dormant in nerve cells and can reactivate later in life when the immune system weakens. Shingles appears as a painful rash with blisters, usually on one side of the body, and can cause symptoms like burning, headache, and fever. The most common complication is postherpetic neuralgia (PHN), a nerve pain that can last for months. Shingles is not directly contagious but the virus can infect someone who never had chickenpox. It mainly affects people over 50 or those with weak immune systems.

Notes:
China has launched 12 satellites to begin building the world’s first space-based supercomputing network, called the Three-Body Computing Constellation. The satellites were launched using a Long March 2D rocket from the Jiuquan Satellite Launch Centre as part of a project led by Zhejiang Lab. These satellites have Artificial Intelligence (AI)-powered processors and high-speed links to communicate and process data in orbit without ground stations. Once complete, the constellation will include 2,800 satellites with a combined power of 1,000 peta operations per second (POPS). The project is developed by ADA Space, Zhijiang Laboratory, and Neijang High-Tech Zone to offer real-time, autonomous data processing from space.

Notes:
Scientists at Raman Research Institute (RRI), Bengaluru, under the Department of Science and Technology, have found a new method to detect topological invariants in quantum materials using the spectral function. The spectral function is a quantum tool that shows how energy and particles like electrons behave inside a material. It is commonly used to study electronic structure such as density of states and dispersion relations. The team focused on momentum-space spectral function (SPSF), which acts like a quantum fingerprint showing how electrons are spread across energy and momentum. This method reveals hidden topological features using values like winding numbers in one-dimensional systems and Chern numbers in two-dimensional systems.

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:
Recently, scientists from the Centre for Nano and Soft Matter Sciences (CeNS), Bengaluru, developed a next-generation device that produces green hydrogen using only solar energy. Green hydrogen is a clean fuel that can help decarbonize industries, power vehicles, and store renewable energy, but producing it affordably at scale has been difficult. The CeNS device splits water molecules using earth-abundant materials without fossil fuels or expensive resources, making it sustainable and scalable.

Notes:
Adani Group has recently commissioned India’s first off-grid 5 megawatt (MW) green hydrogen pilot plant in Kutch, Gujarat. The plant has been developed by Adani New Industries Limited (ANIL), which is the clean energy arm of Adani Enterprises Limited. An off-grid green hydrogen plant produces hydrogen using electrolysis powered entirely by renewable sources like solar or wind and is not connected to the main power grid. This plant runs fully on solar energy and includes a Battery Energy Storage System (BESS) for continuous operation.
