1. What is the causative agent of kala azar disease, that was recently seen in news?
[A] Protozoan Parasite
[B] Virus
[C] Bacteria
[D] Fungus
Show Answer
Correct Answer: A [Protozoan Parasite]
Notes:
Recently, Chad, Djibouti, Ethiopia, Somalia, South Sudan, and Sudan signed a Memorandum of Understanding (MoU) to eliminate visceral leishmaniasis, also known as kala-azar. The event was held during the 78th World Health Assembly in Geneva, organised by the African Union and World Health Organization (WHO). Kala-azar is a neglected tropical disease (NTD) caused by a protozoan parasite and is fatal if untreated, showing symptoms like fever, fatigue, weight loss, and enlarged spleen and liver. More than 70% of global kala-azar cases are in Eastern Africa, where half of the affected are children under 15, according to the Drugs for Neglected Diseases initiative (DNDi). The MoU encourages more investment and better strategies to eliminate kala-azar and improve public health responses.
2. Which institute has developed a tandem solar cell technology that achieves nearly 30% power conversion efficiency?
[A] IIT Bombay
[B] IIT Kanpur
[C] IIT Ahmedabad
[D] IIT Delhi
Show Answer
Correct Answer: A [IIT Bombay]
Notes:
Researchers at the Indian Institute of Technology (IIT) Bombay have developed a new high-efficiency tandem solar cell with nearly 30% power conversion efficiency compared to the current 20%. This innovation was developed at the National Centre for Photovoltaic Research and Education (NCPRE) and uses a four-terminal (4T) tandem structure. The top layer is made of semi-transparent halide perovskite, while the bottom layer uses traditional silicon, allowing both to work independently for better efficiency. Perovskite materials, known for excellent light absorption and low cost, now have improved durability of up to 10 years. The new design also works well in heat and low-light, making it ideal for India’s climate and helping reduce solar energy costs to ₹1 per kilowatt-hour (kWh). This breakthrough boosts India’s clean energy goals by enhancing output and land-use efficiency.
3. Which aerospace company successfully test-fired India’s first electric motor-driven semi-cryogenic engine?
[A] Dhruva Space
[B] Agnikul
[C] Skyroot Aerospace
[D] Digantra
Show Answer
Correct Answer: B [Agnikul]
Notes:
On May 23, 2025, Chennai-based startup Agnikul Cosmos successfully test-fired India’s first electric motor-driven semi-cryogenic engine. This marks a major step for private players in advancing Indian space technology. The engine uses electric motors instead of traditional gas generators to power fuel pumps, allowing precise thrust control and quick response. It runs on semi-cryogenic propulsion using liquid oxygen (LOX) and refined kerosene, balancing performance and cost. This innovation boosts engine reliability and suits future sub-orbital missions.
4. What is the primary objective of a Thrombectomy?
[A] Remove blood clots and restore blood flow
[B] Reduce cholesterol levels
[C] Lower blood pressure
[D] None of the Above
Show Answer
Correct Answer: A [Remove blood clots and restore blood flow]
Notes:
The Technology Development Board (TDB), under the Department of Science and Technology (DST), has announced financial support for India’s first indigenous thrombectomy device. This support aims to improve stroke care by promoting homegrown medical technology. A thrombectomy is a medical procedure to remove blood clots from arteries or veins. These clots, called thrombi, can block blood flow and damage tissues or organs. Thrombectomy helps restore proper blood circulation and prevents serious health risks.
5. Which ministry launched the Bharat Gen Multimodal Large Language Model (LLM) at the BharatGen Summit?
[A] Ministry of Science and Technology
[B] Ministry of Electronics and Information Technology
[C] Ministry of Finance
[D] Ministry of Commerce and Industry
Show Answer
Correct Answer: A [Ministry of Science and Technology]
Notes:
Union Minister of State (Independent Charge) for Science & Technology, Dr. Jitendra Singh launched Bharat Gen Multimodal Large Language Model (LLM) at the BharatGen Summit. BharatGen is India’s first government-funded, indigenously built Artificial Intelligence (AI) based Multimodal Large Language Model. It is developed under the National Mission on Interdisciplinary Cyber-Physical Systems (NM-ICPS) and implemented by the TIH Foundation for Internet of Things (IoT) and Internet of Everything (IoE) at the Indian Institute of Technology (IIT) Bombay.
6. What is “Fusarium graminearum” that was recently seen in news?
[A] Ascomycete fungus
[B] Newly discovered species of fish
[C] Traditional medicine
[D] Critical Mineral
Show Answer
Correct Answer: A [Ascomycete fungus]
Notes:
Recently, two Chinese nationals were charged in the United States for allegedly smuggling Fusarium graminearum, an agricultural pathogen, into the country. Fusarium graminearum is an ascomycete fungus that causes Fusarium Head Blight (FHB), which affects crops like wheat, maize, barley, oats, and rice. It produces a toxin called Vomitoxin or Deoxynivalenol, which is harmful to both humans and animals. This fungus reduces crop yield and quality while contaminating grains with toxic mycotoxins. This incident raises concerns about agro-terrorism, which is the deliberate use of plant pathogens or pests to attack agriculture and create economic loss, food insecurity, and public fear.
7. What is “Astatine” that was recently seen in news?
[A] Radioactive element
[B] Traditional medicine
[C] Newly discovered drug for TB
[D] Asteroid
Show Answer
Correct Answer: A [Radioactive element ]
Notes:
A new scientific breakthrough was made when researchers from the University of Jyväskylä, Finland, successfully measured the half-life of the heaviest proton emitter isotope, 188At (Astatine). Astatine is a rare and highly radioactive element with atomic number 85, and it belongs to the halogen group in the periodic table. Unlike other halogens like fluorine and iodine, astatine has no stable isotopes. It is extremely radioactive, possibly appears as a dark solid, and emits a blue glow due to ionizing radiation. It occurs naturally as a decay product but has a very short half-life.
8. Amoebic Meningoencephalitis, that was recently seen in the news, affects which part of the body?
[A] Kidney
[B] Lungs
[C] Brain
[D] Heart
Show Answer
Correct Answer: C [Brain]
Notes:
The Kerala State Public Health Laboratory has developed its own molecular diagnostic test kits to detect five toxic species of Free-Living Amoeba (FLA). These Free-Living Amoeba (FLAs) can cause Amoebic Meningoencephalitis (AME), a rare but deadly brain infection. Amoebic Meningoencephalitis (AME) is an infection of the brain and its protective membranes called meninges. It is caused by microscopic single-celled organisms found in water. The disease has a mortality rate of over 95% and mainly affects young people. This recent development highlights Kerala’s proactive steps in public health and early disease detection.
9. Diphtheria, which recently caused the largest outbreak in Western Europe, is caused by which agent?
[A] Fungus
[B] Virus
[C] Bacteria
[D] Protozoa
Show Answer
Correct Answer: C [Bacteria]
Notes:
New research revealed the largest diphtheria outbreak in Western Europe in 70 years started in 2022. The outbreak mainly affected vulnerable groups like migrants and the homeless. Diphtheria is a highly contagious bacterial infection caused by bacteria Corynebacterium diphtheriae. This bacteria produces a toxin that attacks the respiratory tract and can spread through the body. Transmission occurs through respiratory droplets from coughing or sneezing. It can also spread by contact with infected open sores or ulcers on the skin.
10. Arsia Mons is a massive shield volcano located in which planet?
[A] Mars
[B] Saturn
[C] Jupiter
[D] Neptune
Show Answer
Correct Answer: A [Mars]
Notes:
NASA’s 2001 Mars Odyssey orbiter recently captured a breathtaking image of Arsia Mons volcano rising above early morning clouds on Mars. Arsia Mons is a giant shield volcano in the Tharsis region of Mars. It stands over 18 kilometers tall and spans more than 300 kilometers wide at its base. It is much larger than Earth’s tallest volcano, Mauna Loa, which is 9 kilometers high. Arsia Mons is the southernmost volcano in the Tharsis Montes group, which includes three major volcanoes.
