Science & Technology Current Affairs MCQs

Notes:
A mysterious illness called “Dinga Dinga” has emerged in Uganda, predominantly affecting women and girls. The name means “shaking like dancing,” reflecting the violent, involuntary body movements it causes. Symptoms include uncontrollable shaking, high fever, extreme weakness, and in severe cases, paralysis-like immobility. The illness impairs mobility, making basic movements like walking impossible for some patients. The cause of Dinga Dinga remains unknown, as health experts have not identified its source. Treatment currently involves antibiotics, though the illness’s origin and effective remedies are still unclear.

Notes:
Turkey successfully tested the UAV-122 supersonic missile fired from the Bayraktar Akinci drone. Bayraktar Akinci is a long-endurance unmanned combat aerial vehicle (UCAV) developed by Turkish manufacturer Baykar. It supports fighter jets with air-to-ground and air-to-air attack capabilities. The drone measures 12.2 m in length, 4.1 m in height, and has a 20 m wingspan. It offers a 25-hour flight time and 7,500 km range. Equipped with AI-powered avionics, dual satellite communication, advanced radars, and collision avoidance systems, it enhances real-time situational awareness. It carries laser-guided munitions, missiles, and long-range weapons and is the first drone capable of launching air-launched cruise missiles.

Notes:
Researchers using South Africa’s MeerKAT radio telescope detected a loud gravitational wave background through the MeerKAT Pulsar Timing Array. The gravitational wave background’s “hot spot” in the Southern Hemisphere was mapped in unprecedented detail. MeerKAT is a radio telescope array in Northern Cape, South Africa, originally called the Karoo Array Telescope (KAT). Initially planned with 20 receptors, it was expanded to 64 receptors and renamed “MeerKAT,” meaning “more of KAT.” It is part of South Africa’s contribution to the global Square Kilometre Array (SKA) project, the world’s largest radio telescope initiative.

Notes:
China is experiencing an outbreak of respiratory infectious diseases, including rhinovirus and human metapneumovirus (HMPV). HMPV cases, especially among children under 14 in northern provinces, are rising. HMPV symptoms include cough, congestion, fever, fatigue, and breathing difficulties; it can lead to bronchitis and pneumonia in vulnerable groups. There is no vaccine or specific antiviral treatment for HMPV; preventive measures like handwashing and avoiding contact are advised.

Notes:
Researchers discovered two rare Neuroptera species, Indophanes barbara and Glenochrysa zeylanica, in Kerala. Indophanes barbara, an antlion from the Myrmeleontidae family, does not build pits like other antlion larvae and lives in loose soil for protection. Adult Indophanes barbara resemble damselflies but can be identified by their long antennae and belong to holometabolous Neuroptera insects, unlike hemimetabolous damselflies. Glenochrysa zeylanica, a green lacewing from the Chrysopidae family, was rediscovered in Wayanad after 111 years and reported for the first time in India. Neuroptera, commonly called lacewings, are terrestrial insects with complex wing vein patterns.

Notes:
Researchers developed the first nanobody-based inhibitors targeting the Ebola virus. Ebola is caused by ortho ebola viruses, discovered in 1976 in the Congo, primarily found in sub-Saharan Africa. The virus gets its name from the Ebola River in Congo. Fruit bats are natural hosts, and it spreads through contact with infected animals or humans. Symptoms include fever, diarrhea, vomiting, bleeding, and often death. The average fatality rate is around 50%. There is no cure exists for Ebola. Experimental treatments like monoclonal antibodies have been used. Treatment focuses on fluid balance, blood plasma, and early intervention for better recovery chances.

Notes:
Bangalore Medical College and Research Institute (BMCRI) has been selected by Indian Council of Medical Research (ICMR) to host South India’s first Infectious Disease Research and Diagnostic Laboratory (IRDL). The lab will focus on research and diagnostics for bacterial, fungal, and parasitic infections, enabling quicker and more accurate disease management. This is part of a nationwide initiative to enhance medical research infrastructure in India. The lab will also study antibiotic resistance, fungal infections, and tropical diseases.

Notes:
The Prime Minister praised Indian space startup Digantara for the success of its Mission SCOT. SCOT (Space Camera for Object Tracking) is Digantara’s first mission for space surveillance and one of the world’s first commercial Space Situational Awareness (SSA) satellites. It was launched aboard SpaceX’s Transporter-12 mission and deployed in a sun-synchronous orbit. SCOT is designed to track Resident Space Objects (RSOs) as small as 5 cm in Low Earth Orbit (LEO) with high accuracy and revisit rates. It addresses gaps in existing systems limited by fields of view, weather, and geography.

Notes:
Around 59 people in Pune have been affected by Guillain-Barre Syndrome (GBS), a rare neurological disorder. GBS occurs when the immune system attacks the peripheral nervous system, affecting muscle movement, pain, temperature, and touch sensations. It is also called acute inflammatory demyelinating polyradiculoneuropathy (AIDP) and usually affects people aged 30-50. The exact cause is unclear but often follows infections, vaccinations, or major surgery. Symptoms include fever, weakness, and potential paralysis, with severity varying widely. There is no cure, but intravenous immunoglobulin (IVIG) treatment helps suppress the immune system’s attack on the nerves.

Notes:
ISRO launched the Geosynchronous Satellite Launch Vehicle (GSLV) rocket carrying the NVS-02 satellite for the NavIC (Navigation with Indian Constellation) navigation system. NVS-02 is the second of five second-generation satellites to replace older ones in India’s navigation constellation. It weighs 2,250 kg, has a 3 kW power capacity, and includes navigation payloads in L1, L5, S, and C bands. The satellite features a Rubidium Atomic Frequency Standard for precise timekeeping and has a 12-year lifespan.
