Science & Technology Current Affairs MCQs

Notes:
Google announced that its quantum processor Willow has achieved the first “verifiable” quantum advantage. Quantum advantage means a quantum computer can outperform a classical computer in practice. The announcement was accompanied by an open-access paper in Nature by the Google Quantum AI and Collaborators team. Willow ran a new algorithm, Quantum Echoes, 13,000 times faster than the best classical algorithm on a supercomputer. The experiment used a technique called out-of-time-order correlator (OTOC) to track how information scrambles in quantum systems. OTOC measures how quantum information spreads, is scrambled, and can be “unscrambled” using time-reversal. Willow’s processor precisely controlled quantum bits (qubits) in a chaotic quantum system for the experiment.

Notes:
China developed the underwater drone nicknamed the “ghost jellyfish”. The drone is made of a soft hydrogel material, has a transparent body, and uses electrostatic hydraulic actuators to mimic the natural, silent movement of a real jellyfish. It is equipped with an AI chip and a micro-camera for real-time object identification and can operate with very low energy consumption. Its primary uses are for stealthy underwater reconnaissance, ecological monitoring, and observing marine life without causing disruption.

Notes:
Scientists have recently developed a breakthrough therapy that clears toxic proteins from nerve cells, offering new hope for treating Motor Neuron Disease (MND). Motor Neuron Disease (MND), also known as Amyotrophic Lateral Sclerosis (ALS) or Lou Gehrig’s Disease, is a rare condition that damages parts of the nervous system. It causes muscle weakness, wasting, and paralysis as motor neurons in the brain and spinal cord die prematurely, stopping signals between the brain and muscles. Around 20% of cases are genetic, mostly affecting people over 50 years old. There is currently no cure, but treatment helps manage symptoms.

Notes:
Recently, Jamaica declared an outbreak of leptospirosis after the destruction caused by Hurricane Melissa. Leptospirosis is a fatal bacterial disease. It is caused by the bacterium Leptospira interrogans, also called Leptospira. The bacteria enter the human body through tiny cracks or wounds in the skin, especially on the feet. It is more common in warm and humid regions across both urban and rural areas. The disease is contagious in animals and occasionally infects humans under suitable environmental conditions.

Notes:
The Entrepreneur-in-Residence Programme is becoming popular among young startups and innovators. It works under the National Initiative for Developing and Harnessing Innovations which is NIDHI. It encourages graduate students to choose entrepreneurship as a career. It provides financial and non-financial support in the form of a fellowship. It offers startup infrastructure, mentoring, technical guidance, and industry support. It is implemented by the Department of Science and Technology with NCL Venture Centre.

Notes:
Telangana’s 1 Bio, India’s first single-use bioprocess design and scale-up facility, was inaugurated at Genome Valley, Hyderabad. It was created to solve the lack of affordable bioprocess scale-up infrastructure despite Telangana’s strong biotech talent. The facility supports start-ups and big companies with end-to-end process development and pilot validation. It was developed by the Government of Telangana, Telangana Lifesciences, Department of Biotechnology (DBT), Government of India, and Telangana Industrial Infrastructure Corporation (TGIIC). It has 500-litre bioreactors, advanced processing systems, and analytical labs.

Notes:
Niger became the first country in the African Region to eliminate onchocerciasis, also called river blindness. Niger is the fifth country worldwide to stop transmission of Onchocerca volvulus parasite. Other successful countries are Colombia, Ecuador, Guatemala, and Mexico in the Americas. World Health Organisation (WHO) praised Niger’s strong leadership and public health efforts. Onchocerciasis is the second leading infectious cause of blindness after trachoma. It spreads through bites of infected black flies found near rivers. It mainly affects rural areas of sub-Saharan Africa and Yemen, and some parts of Latin America.

Notes:
A recent study found that the shingles vaccine can reduce the risk of death from dementia. Shingles is a viral infection that causes a painful skin rash. It is caused by the varicella-zoster virus, the same virus responsible for chickenpox. After chickenpox, the virus stays dormant in nerve cells and can reactivate when immunity becomes weak. Shingles usually appears as a painful stripe of blisters on one side of the body, face, or neck. It is not directly contagious but can spread chickenpox to unvaccinated people. It mainly affects people over 50 years or those with weak immune systems. The Shingrix vaccine helps prevent shingles and its complications.

Notes:
Indian Institute of Technology Bombay (IIT Bombay) has hosted ATMAN 3.0, an eight-week Health Technology (HealthTech) accelerator programme. The programme is conducted by the Technology Innovation Hub (TIH) at IIT Bombay. ATMAN 3.0 is supported by the National Mission on Interdisciplinary Cyber-Physical Systems (NM-ICPS) and the Department of Science and Technology (DST). It aims to transform early-stage HealthTech startups into investment-ready ventures. Thirteen startups were selected from 173 applicants after a competitive pitching process. Each selected startup can receive seed funding support of one crore rupees or more. The programme will conclude with a Demo Day on 9 January 2026 at Novotel, Mumbai International Airport.

Notes:
Kavach is an indigenously developed Automatic Train Protection (ATP) system designed to improve railway operational safety across the Indian Railways network. It was developed by the Research Design and Standards Organisation (RDSO) of Indian Railways. As of December 2025, the system has been commissioned on over 2,000 km of railway routes, with 7,129 km of Optical Fibre Cable (OFC) laid, 860 telecom towers installed, 767 stations connected, 3,413 km of trackside equipment deployed, and 4,154 locomotives fitted with Kavach. About 40,000 technicians and operators have been trained, reflecting the scale of operational readiness.
