1. Which country’s scientists developed a simpler portable ion chromatograph called Aquamonitrix for field use?
[A] India
[B] Australia
[C] Germany
[D] New Zealand
Show Answer
Correct Answer: B [Australia]
Notes:
Scientists at the University of Tasmania, Australia, developed a portable ion chromatograph called Aquamonitrix to perform ion separation in the field. The device was tested by undergraduate students who analysed soil pore water for harmful nitrate and nitrite ions immediately after collection. Results were comparable to expensive lab-based chromatographs, proving accuracy with lower cost and time. Aquamonitrix uses sodium chloride solution and a UV absorbance detector, making it simple, eco-friendly, and effective. The portable device costs about 10,000 versus 100,000 for conventional lab instruments. It provides hands-on field experience for students, linking theory with real-world environmental analysis.
2. Japanese Encephalitis (JE), that was recently seen in news, is caused by which agent?
[A] Bacteria
[B] Virus
[C] Fungus
[D] Protozoa
Show Answer
Correct Answer: B [Virus]
Notes:
Mosquito-borne diseases like dengue fever are rising due to rapid urbanisation, climate change, and global travel. A new study published on 3 September in Science Translational Medicine shows waning immunity against Japanese Encephalitis Virus (JEV) can worsen dengue outcomes. Japanese Encephalitis (JE) is a viral zoonotic disease caused by the Japanese Encephalitis (B) virus. Transmission occurs through infected Culex mosquitoes of the Vishnui group, not from human to human. It is most common in rural Asia, especially during monsoon seasons. Both viruses belong to the genus Orthoflavivirus and show cross-immune interactions.
3. What is the causative agent of False Smut Disease, that was recently seen in news?
[A] Bacteria
[B] Virus
[C] Fungus
[D] Protozoa
Show Answer
Correct Answer: C [Fungus]
Notes:
In Punjab, incessant rainfall and floods stopped farmers from spraying anti-fungal medicines. This has led to the emergence of false smut disease, locally called haldi rog, in paddy crops. False smut is a major fungal disease of rice caused by Ustilaginoidea virens. The fungus attacks during the flowering stage, but symptoms appear after panicle emergence. Infected grains show black fungal growth, later covered with yellow fungal mass. It reduces seed germination and significantly lowers yield depending on infection level.
4. What is Asphyxia, which recently caused deaths in the TVK rally stampede at Velusamypuram?
[A] Excessive bleeding due to injury
[B] Condition when the body does not get enough oxygen
[C] Poisoning from contaminated food
[D] None of the Above
Show Answer
Correct Answer: B [Condition when the body does not get enough oxygen]
Notes:
The death toll in the stampede at Tamilaga Vetri Kazhagam (TVK) rally in Velusamypuram has risen to 41. Doctors reported most fatalities were due to compressive asphyxia caused by crowd crush. Asphyxia occurs when the body does not get enough oxygen. Respiration moves oxygen into the lungs and circulates it via blood to all body cells, while carbon dioxide is removed. Lack of oxygen can cause unconsciousness or death. Compressive asphyxia happens when an external force prevents chest expansion, crushing the lungs and stopping breathing. This can occur in crowded situations or from a person’s weight on the chest.
5. What kind of disease is Crohn’s disease that was recently seen in news?
[A] A respiratory disorder
[B] Autoimmune neurological disorder
[C] A heart disease
[D] A chronic inflammatory bowel disease
Show Answer
Correct Answer: D [A chronic inflammatory bowel disease ]
Notes:
Recent research shows that eating diets high in Ultra Processed Foods (UPFs) can worsen gut inflammation and increase Crohn’s disease flare-ups. Crohn’s Disease is a chronic Inflammatory Bowel Disease (IBD) that causes swelling and irritation in the digestive tract. It usually affects the small intestine and the beginning of the large intestine. Inflammation can spread deep into the bowel layers, causing pain and serious complications. Common symptoms include diarrhea, abdominal cramps, and weight loss. It mostly develops between ages 20 and 29. The exact cause is unknown but may involve genes, immune reactions, and the microbiome. There is no cure, but treatment helps control symptoms and maintain remission.
6. Which country has become the first in the world to achieve triple elimination of mother-to-child transmission of hepatitis B, HIV, and syphilis?
[A] Sri Lanka
[B] Maldives
[C] Thailand
[D] Indonesia
Show Answer
Correct Answer: B [Maldives]
Notes:
Maldives has become the first country in the world to achieve triple elimination of mother-to-child transmission of hepatitis B, HIV, and syphilis. The World Health Organization (WHO) has validated Maldives for eliminating mother-to-child transmission of hepatitis B. According to WHO, around 25,000 HIV-positive pregnant women globally need treatment to prevent transmission to babies. Hepatitis B still affects over 42 million people in the WHO Southeast Asia Region. In Maldives, over 95% of pregnant women receive antenatal care with almost universal testing for HIV, syphilis, and hepatitis B.
7. Which Indian research institute has developed a nanotechnology-based method using the coffee-ring effect to detect toxic molecules like Rhodamine B?
[A] Indian Institute of Science (IISc), Bengaluru
[B] Raman Research Institute (RRI), Bengaluru
[C] National Chemical Laboratory (NCL), Pune
[D] Bhabha Atomic Research Centre (BARC), Mumbai
Show Answer
Correct Answer: B [Raman Research Institute (RRI), Bengaluru]
Notes:
Scientists at the Raman Research Institute (RRI), India developed a sensitive method to detect toxic molecules like Rhodamine B. The method uses the coffee-ring effect combined with nanotechnology for enhanced detection. The coffee-ring effect occurs when a droplet evaporates, and capillary flow moves particles from the center to the edge, forming a ring-shaped deposition pattern. Rhodamine B is a water-soluble synthetic dye with bright pink fluorescence. It is widely used in fluorescence microscopy, flow cytometry, and ELISA biochemical assays. Rhodamine B is toxic and carcinogenic, affecting skin, eyes, and the respiratory system. This method provides a rapid and effective tool for detecting hazardous dyes in research and environmental monitoring.
8. Which Indian lunar mission made the first-ever observation of the effect of the Sun’s coronal mass ejection (CME) on the Moon?
[A] Chandrayaan-1
[B] Chandrayaan-2
[C] Chandrayaan-3
[D] Aditya-L1
Show Answer
Correct Answer: B [Chandrayaan-2]
Notes:
Chandrayaan-2, India’s second lunar mission, made the first direct observation of the Sun’s Coronal Mass Ejection (CME) effects on the Moon. The observation was made by CHACE-2 (Chandra’s Atmospheric Composition Explorer-2), a payload onboard the orbiter. Indian Space Research Organisation (ISRO) reported that the dayside lunar exosphere pressure increased when the CME impacted the Moon. The total number density of neutral atoms or molecules increased more than tenfold, confirming theoretical predictions for the first time. Chandrayaan-2, launched on 22 July 2019 via GSLV Mk-III M1, carried eight experiment payloads; however, the Vikram lander lost communication during its soft-landing attempt.
9. Amoebic Meningoencephalitis, that was recently seen in the news, affects which part of the body?
[A] Kidneys
[B] Brain
[C] Heart
[D] Lungs
Show Answer
Correct Answer: B [Brain]
Notes:
Kerala reported another death from Amoebic Meningoencephalitis (Primary Amebic Meningoencephalitis, PAM), raising the 2025 toll to 27 cases. Primary Amebic Meningoencephalitis is a rare, fatal brain infection caused by the free-living amoeba Naegleria fowleri, known as the “brain-eating amoeba.” Infection occurs when contaminated freshwater enters the nasal cavity, allowing the amoeba to reach the brain via the olfactory nerve. It is found in warm freshwater and soil, especially lakes, rivers, hot springs, and unchlorinated pools.

[A] Indian Council of Medical Research (ICMR)
[B] NITI Aayog
[C] Ministry of Health
[D] IIT Delhi
Show Answer
Correct Answer: A [Indian Council of Medical Research (ICMR)]
Notes:
The Anusandhan National Research Foundation (ANRF), in collaboration with Indian Council of Medical Research (ICMR) and the Gates Foundation, launched the Mission for Advancement in High-Impact Areas (MAHA)-Medical Technology recently. MAHA MedTech Mission aims to boost innovation in India’s medical technology sector, reduce dependence on high-cost imports, and ensure affordable, high-quality medical technologies. The mission supports development and commercialization of innovative and affordable MedTech solutions.
