Science & Technology Current Affairs MCQs

Notes:
The 75/25 initiative has reached 89.7% of its goal, providing hypertension treatment to 42.01 million people and diabetes treatment to 25.27 million. It was launched on World Hypertension Day 2023. It aims to provide standardized care to 75 million individuals by December 2025. Primary Health Centres (PHCs) play a key role in delivering treatment. The initiative follows strategies under the National Programme for Prevention and Control of Non-Communicable Diseases (NP-NCD). It focuses on improving healthcare access and managing lifestyle diseases effectively.

Notes:
Tanzania declared the end of its second Marburg Virus Disease (MVD) outbreak after 42 days with no new cases. MVD was first identified in 1967 in Marburg, Germany, when laboratory workers were exposed to infected green monkeys from Uganda. It is caused by the Marburg virus (MARV), a highly infectious RNA virus from the Filoviridae family, similar to Ebola. The African fruit bat (Rousettus aegyptiacus) is the natural reservoir of the virus, carrying it without symptoms.

Notes:
V Narayanan, Chairman of ISRO, inaugurated the ‘Shri S. Ramakrishnan Centre of Excellence in Fluid and Thermal Science Research’ at IIT Madras on March 17, 2025. The centre supports ‘Atmanirbhar Bharat’ by advancing space technologies and attracting global research talent. It focuses on spacecraft and launch vehicle thermal management, crucial for India’s space missions. S Ramakrishnan, an IIT Madras alumnus, contributed significantly to PSLV and GSLV MK3 development. ISRO scientists will collaborate with IIT Madras to develop advanced cooling systems for spacecraft. The research will support future lunar, Mars, and deep-space missions.

Notes:
Serbian government is accused of using a banned sonic weapon to disperse protesters in Belgrade. Sonic weapons, also called acoustic weapons, emit loud, painful sounds over long distances. They can use audible or inaudible sound waves to disrupt, disorient, or incapacitate people. Some versions amplify voices for crowd control. It was first developed for military use. The U.S. used them in Iraq in 2004. They work with transducers that convert energy into sound waves. Highly concentrated sound beams can cause discomfort, pain, and disorientation. Authorities control frequency, volume, and duration for targeted impact.

Notes:
Subacute sclerosing panencephalitis (SSPE) is a fatal brain disorder linked to measles (rubella) infection. It can develop years after measles recovery, affecting children and adolescents, with men at higher risk. Low measles vaccination coverage in Uttar Pradesh has made SSPE a serious health concern. SSPE cases are reported worldwide but remain rare in Western countries.

Notes:
Noma is a severe, gangrenous disease of the mouth and face, also called cancrum oris or gangrenous stomatitis. The World Health Organization classified it as a neglected tropical disease in December 2023. It mostly affects children aged 2–6 years suffering from malnutrition, infections, extreme poverty, poor oral health, or weakened immunity. It starts as a gum sore and rapidly destroys soft tissues, hard tissues, and facial skin. It is non-contagious and caused by polymicrobial organisms. Early treatment includes antibiotics, oral hygiene support, mouthwash, and nutrition supplements.

Notes:
The European Space Agency (ESA) shut down the Gaia space observatory on March 27, 2025. It was launched in 2013 by European Space Agency (ESA). Gaia aimed to create the most precise 3D map of the Milky Way. Originally named Global Astrometric Interferometer for Astrophysics (GAIA), later simplified to Gaia. It is positioned at Lagrange Point 2 (L2), 1.5 million km from Earth, for an unobstructed view.

Notes:
African Swine Fever (ASF) has resurged in Mizoram, causing 41 more pig deaths, raising the total toll to 503 since March 20. ASF first emerged in Mizoram in Lungsen village, Lunglei, on March 21, 2021, and has since become endemic. The causative agent of African Swine Fever (ASF) is the African Swine Fever Virus (ASFV). ASF is a highly contagious and fatal viral disease affecting domestic and wild pigs but poses no risk to humans. The virus can spread through contaminated clothing, equipment, or vehicles, threatening pig populations. There is no treatment or vaccine, making prevention and strict biosecurity measures the only effective control methods.

Notes:
An international team of astronomers has used the Transiting Exoplanet Survey Satellite (TESS) to discover a new warm Jupiter-type exoplanet over 1,000 light years away. TESS is a NASA mission launched in March 2018 to detect exoplanets orbiting bright dwarf stars by observing small dips in star brightness caused by planet transits. It followed the Kepler space telescope and used the transit method to study planet size and orbit. In its two-year prime mission, which ended in July 2020, TESS imaged 75% of the sky and discovered 66 new exoplanets. TESS continues its work under an extended mission.

Notes:
Bangladesh has become the 54th country to sign the Artemis Accords, a global agreement for safe and peaceful space exploration. The signing took place in Dhaka, where Secretary of Defense Ashraf Uddin represented Bangladesh. The Artemis Accords promote cooperation, transparency, and responsible behavior in space missions like those to the Moon and beyond. It was originally launched in 2020 by NASA and the US Department of State. They are based on the Outer Space Treaty and other agreements like the Rescue and Return Agreement. Bangladesh’s entry marks its growing role in global space efforts and strengthens ties with NASA and international partners.
