Science & Technology Current Affairs MCQs

Notes:
A mysterious crying disease in the Democratic Republic of the Congo (DRC) has caused over 60 deaths and infected more than 1,096 people in Western Congo. The disease was first identified in three children who ate bat and has spread rapidly. Symptoms include fever, vomiting, internal bleeding, diarrhea, body ache, intense thirst, joint pain, incessant crying, nose bleeding, and vomiting blood. The disease can kill within 48 hours, raising serious concerns. Tests ruled out Ebola, dengue, Marburg, and yellow fever, but the exact cause remains unknown. WHO is investigating whether it is an infection or a toxic agent.

Notes:
Prince Frederik of Luxembourg, 22, recently died from a rare genetic disease called POLG. POLG is a mitochondrial disorder that prevents cells from producing enough energy, leading to organ failure. It primarily affects the brain, nerves, muscles, liver, and sometimes vision. Patients often become bedridden and lose the ability to perform daily activities. The disease is caused by mutations in the POLG and POLG2 genes, affecting mitochondrial replication. Symptoms range from muscle weakness and seizures to liver failure and difficulty walking. There is no cure; treatment focuses on symptom management and quality of life improvement.

Notes:
Airtel and Jio have partnered with Starlink, SpaceX’s satellite internet service, to provide broadband in India. Starlink is a satellite-based internet network operated by SpaceX and founded by Elon Musk. It was launched in 2019. It aims to offer high-speed, low-latency internet globally, especially in remote areas. The project plans to deploy 42,000 satellites in low-Earth orbit (LEO). Starlink works by using a constellation of LEO satellites to provide connectivity. A Starlink dish connects to the nearest satellite, which relays data through ground stations, eliminating dependence on fiber or cellular networks.

Notes:
NASA reported that global sea levels rose faster than expected in 2024. The rise reached 0.59 cm per year, exceeding the expected 0.43 cm. The main causes are ocean warming, which leads to expansion, and meltwater from glaciers and ice sheets. In 2024, thermal expansion caused two-thirds of the rise, shifting from previous years when melting ice was the dominant factor. 2024 was the warmest year on record, with ocean levels at their highest in three decades. Since satellite monitoring began in 1993, global sea levels have risen by 10 cm, with the rate more than doubling.

Notes:
The Ministry of Electronics and Information Technology (MeitY) and Drone Federation India (DFI) launch National Innovation Challenge for Drone Application and Research (NIDAR) under the SwaYaan initiative to boost drone innovation. NIDAR aims to engage students and researchers in developing autonomous drones for real-world challenges. SwaYaan focuses on building human resources in Unmanned Aircraft Systems (UAS), including drones. It was approved in July 2022. It targets training 42,560 participants through formal and non-formal programs to create a skilled drone workforce.

Notes:
IIT Guwahati developed India’s first VR-enabled metaverse platform for schools, called Gyandhara. Gyandhara provides an immersive and engaging learning experience. It helps students understand scientific and academic concepts that are difficult to grasp through traditional learning. The platform enhances education through virtual reality, making learning interactive and effective.

Notes:
Researchers in Sweden have discovered a new type of magnetism called altermagnetism. It combines the properties of ferromagnets and antiferromagnets in one material. Conventional magnets like iron and nickel rely on aligned spins, while antiferromagnets cancel magnetic forces. Altermagnets have zero net magnetization like antiferromagnets but also show spin splitting like ferromagnets. They can increase the speed of memory devices and improve the efficiency of electronic systems.

Notes:
DNA polymorphism is widely used in forensics and medicine. It refers to variations in DNA segments or genes among individuals. Detection techniques include Restriction Fragment Length Polymorphism (RFLP) and Variable Number of Tandem Repeats (VNTR) polymorphism. DNA profiles are created using polymorphisms in short tandem repeats (STRs). STRs are short DNA sequences repeated multiple times at specific locations. Applications include molecular and personalized medicine, forensic DNA analysis, DNA linkage studies, and identity differentiation.

Notes:
The Future Circular Collider (FCC) is a proposed $30 billion project by the European Organization for Nuclear Research (CERN). It involves a 91 km circular tunnel beneath the Swiss-French border to accelerate and collide particles at record energies. Phase 1 (~2040) aims to generate Higgs bosons in large numbers, while Phase 2 (~2070) will collide protons at extreme energies. Supporters, including CERN leadership, call it the most powerful tool for studying nature. Critics argue it may drain funds, limiting investment in other scientific advancements. The project has sparked major divisions in the scientific community.

Notes:
The government has launched ZooWIN, a digital platform to track real-time availability of anti-rabies vaccines (ARV) and anti-snake venom (ASV) nationwide. ZooWIN is similar to Co-WIN and U-WIN, centralizing data for better coordination among healthcare providers, municipal authorities, and veterinary services. It supports the Union Health Ministry’s efforts to combat rabies and snakebites under the National Action Plan for Prevention and Control of Snakebite Envenoming (NAPSE). India records 3–4 million snakebites annually, causing around 50,000 deaths, half of the global snakebite mortality. The platform is initially piloted in Delhi, Madhya Pradesh, Assam, Puducherry, and Andhra Pradesh.
