Science & Technology Current Affairs MCQs

Notes:
Recently, reports claim the Trump administration asked NASA to shut down Orbiting Carbon Observatories (OCO). The Orbiting Carbon Observatory (OCO) Program, managed by NASA’s Jet Propulsion Laboratory (JPL), is an initiative of NASA. OCO are Earth remote sensing satellites designed to monitor atmospheric carbon dioxide (CO₂) from space to understand climate change.

Notes:
Recently, Kerala’s health department issued an alert in Kozhikode after three cases of Primary Amoebic Meningoencephalitis (PAM) were reported. Primary Amoebic Meningoencephalitis (PAM) is a brain infection caused by Naegleria fowleri, also called the “brain-eating amoeba.” This amoeba lives in warm freshwater, soil, swimming pools, hot tubs, and infects through the nose. It mainly affects young, active people and has a mortality rate above 95%. Primary Amoebic Meningoencephalitis (PAM) progresses rapidly and is often fatal within days, while Granulomatous Amebic Encephalitis (GAE) progresses slowly.

Notes:
Pseudomonas aeruginosa is a gram-negative, aerobic, non-spore-forming rod bacterium commonly found in soil and water. It is the most common type of Pseudomonas causing human infections in the blood, lungs (pneumonia), urinary tract, and post-surgery sites. Researchers from Germany found that P. aeruginosa shows bistable expression of the glpD gene, meaning activity varies among genetically identical cells. This variation affects its infection-causing ability, as shown in tests on moth larvae and mouse immune cells. Targeting glpD gene’s variable expression could help combat hospital-acquired P. aeruginosa infections. This discovery highlights new directions for infection control and antibiotic strategies.

Notes:
The National Supercomputing Mission (NSM) was launched in April 2015 by the Government of India with a budget of Rs.4,500 crore. Its vision is to achieve self-reliance and global leadership in supercomputing and provide state-of-the-art facilities to researchers. It is jointly implemented by the Ministry of Electronics and Information Technology (MeitY) and the Department of Science and Technology (DST) through Centre for Development of Advanced Computing (C-DAC), Pune and Indian Institute of Science (IISc), Bengaluru. As of August 2025, 37 supercomputers with 40 Petaflops capacity are installed across IITs, IISc, R&D labs and Tier-II/III cities. This information was submitted in the Lok Sabha today by Shri Jitin Prasada, Minister of State for Electronics and Information Technology.

Notes:
Seaweed farming has emerged as a potential Blue Carbon strategy, but empirical estimates of carbon burial from these farms are still limited. Blue Carbon refers to organic carbon captured and stored by oceans in vegetated coastal ecosystems such as mangrove forests, saltmarshes, and seagrass meadows. The term “Blue” highlights the watery nature of this carbon storage. Most blue carbon is carbon dioxide dissolved directly into the ocean. These ecosystems cover 2% of the ocean surface but account for 50% of the ocean’s carbon absorption. Blue carbon ecosystems are crucial for global climate change mitigation.

Notes:
European Space Agency (ESA) Solar Orbiter, a joint project with NASA, was launched in 2020 to study the Sun closely. It became the first spacecraft to image the Sun’s poles. A new study in Astronomy and Astrophysics traced the origin of Solar Energetic Electrons (SEE) emitted by the Sun. Solar Energetic Electrons (SEE) linked to solar flares arise from small surface explosions, while others are released gradually with Coronal Mass Ejections (CME), huge eruptions of plasma and magnetic fields. The Solar Orbiter flew through electron streams and studied the space environment between the Sun and spacecraft. Understanding SEE and CMEs is crucial for space weather prediction, protecting satellites, GPS, power grids, and astronauts. The mission aims to study the Sun’s 11-year magnetic cycle, corona heating, solar wind formation, and acceleration.

Notes:
Acanthamoeba, a free-living amoeba, is now a public health concern in Kerala causing eye (keratitis) and brain infections (amoebic meningoencephalitis). Acanthamoeba is a free-living amoeba found in water, soil, dust, swimming pools, hot tubs, and drinking water systems. It can also exist in humidifiers and heating, ventilation, and air conditioning (HVAC) systems. It causes infections in brain, skin, eyes, and sinuses. It enters through cuts, wounds, inhalation, or contact lens use.

Notes:
Researchers at Jawaharlal Nehru Tropical Botanic Garden & Research Institute (JNTBGRI), Palode, Thiruvananthapuram, developed a multifunctional wound-healing pad. The pad is based on the red ivy plant, locally called murikooti pacha, scientifically Strobilanthes alternata of the Acanthaceae family. Scientists at the Centre of Excellence in Phytochemical Nanotechnology of JNTBGRI isolated a new molecule, acteoside, from red ivy for the first time. Acteoside shows high efficacy even at 0.2% concentration and is the key ingredient in the pad. The pad uses electro-spun nanofiber layers made from biodegradable, non-toxic, FDA-approved polymers. Red ivy has long been used in traditional medicine for treating cuts and wounds.

Notes:
Researchers at Stanford University and the Arc Institute created the world’s first entirely AI-generated genome. The AI-designed virus can infect and kill bacteria, acting as a bacteriophage. Artificial Intelligence (AI) model named Evo was used, employing genome “language models” to design complete viral genomes. Evo was trained on about 2 million viral genomes to learn DNA patterns, gene order, and composition. Scientists guided Evo to mimic phiX174, a small bacteriophage with 11 genes and approximately 5,000 DNA letters. This achievement marks a significant advancement beyond AI-designed proteins or small multi-gene systems. It demonstrates AI’s potential to innovate in synthetic biology and genome engineering.

Notes:
The Ministry of Ayush inaugurated “Prayas,” an Integrated Neuro-Rehabilitation Centre at the All India Institute of Ayurveda (AIIA), Goa, on the 10th Ayurveda Day. “Prayas” is among the first multidisciplinary centres in India integrating Ayurveda, Physiotherapy, Yoga, Speech Therapy, Occupational Therapy, and modern Paediatrics. The facility focuses on holistic neuro-rehabilitation, especially for children with neurological and developmental conditions. It aims to provide treatment, research, training, and renewed quality of life for patients. The initiative aligns with India’s National Health Policy and global integrative healthcare practices.
