1. What kind of disease is “Sarcoidosis” that was recently seen in news?
[A] Autoimmune inflammatory disease
[B] Nutritional deficiency disorder
[C] Neurological disorder
[D] None of the Above
Show Answer
Correct Answer: A [Autoimmune inflammatory disease]
Notes:
Recently, a study in Nature Reviews Disease Primers gave an in-depth analysis of sarcoidosis. Sarcoidosis is an inflammatory disease where immune cells form granulomas in organs, mainly lungs. Granulomas are most common in lungs and lymph nodes but can also affect eyes, skin, heart, and other organs. Exact cause is unknown but linked to genetic changes and triggers like bacteria, viruses, dust, or chemicals. Symptoms range from mild to severe, including cough, breathlessness, shin sores, eye pain, and redness. Some cases resolve on their own, while others become chronic and may lead to fibrosis with lung scarring. There is no cure, but treatment with medicines reduces immune overreaction and prevents organ damage.
2. Hand, Foot, and Mouth Disease (HFMD), 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:
A viral infection called Hand, Foot, and Mouth Disease (HFMD) is spreading rapidly among children in Delhi and Haryana, prompting advisories. It is a highly contagious illness caused by a virus. It causes blister-like rashes on hands and feet, painful mouth sores, and sometimes rashes on chest, back, arms, legs, genitals, and buttocks. It mostly affects infants and children under 5 years, spreading quickly in schools and daycare. It is different from foot-and-mouth disease in animals, caused by a different virus. Transmission happens through unwashed hands, saliva, mucus, feces, or blister fluid. No cure or vaccine exists; recovery usually takes 7–10 days with basic care. Complications are rare, but children under 2 may take longer to recover.
3. Which institutions recently created the world’s first entirely AI-generated genome?
[A] California Institute of Technology and Harvard University
[B] Massachusetts Institute of Technology (MIT) and University of Oxford
[C] Harvard University and University of Cambridge
[D] Stanford University and the Arc Institute
Show Answer
Correct Answer: D [Stanford University and the Arc Institute]
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.
4. Astronomers recently detected phosphine (PH₃) in the atmosphere of brown dwarf Wolf 1130C using which telescope?
[A] Hubble Space Telescope
[B] James Webb Space Telescope
[C] Spitzer Space Telescope
[D] Chandra X-ray Observatory
Show Answer
Correct Answer: B [James Webb Space Telescope]
Notes:
Astronomers using the James Webb Space Telescope (JWST) recently detected phosphine (PH3) in the atmosphere of brown dwarf Wolf 1130C. Phosphine is a chemical compound consisting of one phosphorus atom and three hydrogen atoms. On Earth, phosphine is naturally produced by bacteria in low-oxygen environments. These bacteria absorb phosphate from minerals or biological material and combine it with hydrogen to form phosphine. Phosphine is also present in the atmospheres of Jupiter and Saturn. The compound is also known as hydrogen phosphide. Its detection in Wolf 1130C provides insights into chemical processes in brown dwarf atmospheres.
5. Rotovac vaccine, that was recently seen in news, is used for the prevention/treatment of which disease?
[A] Measles
[B] Tuberculosis
[C] Rotavirus
[D] Polio
Show Answer
Correct Answer: C [Rotavirus]
Notes:
A recent study found that the indigenous rotavirus vaccine ‘Rotavac’ is as effective in real-world use as in clinical trials. Rotavac is an oral, live attenuated, monovalent liquid vaccine against rotavirus. It was developed through a public-private partnership involving the Department of Biotechnology (DBT), Bharat Biotech, and the U.S. National Institutes of Health (NIH). Rotavirus is a viral disease that commonly causes diarrhoeal illness in children. There is no specific medicine to treat rotavirus infection, and vaccination provides the best protection. This study highlights Rotavac’s continued role in child health.
6. What is the name of India’s first indigenous CAR-T Cell Therapy recently unveiled at the Emerging Science, Technology & Innovation Conclave 2025?
[A] CARIND-1
[B] NexCAR19
[C] BioCure-India
[D] None of the Above
Show Answer
Correct Answer: B [NexCAR19]
Notes:
In a historic milestone, Prime Minister Narendra Modi unveiled NexCAR19, India’s first indigenous CAR-T Cell Therapy, at the Emerging Science, Technology & Innovation Conclave (ESTIC) 2025 in Delhi. It is developed by ImmunoACT, an IIT Bombay spin-off. It is supported by the Department of Biotechnology (DBT) and Biotechnology Industry Research Assistance Council (BIRAC). NexCAR19 is the world’s first humanised CAR-T therapy, truly “Made in India, for the world.” CAR-T Cell Therapy is an immunotherapy that reprograms a patient’s immune cells to fight blood cancers like Acute Lymphocytic Leukemia (ALL).
7. Which cities have been selected for the development of the four Hydrogen Valley Innovation Clusters (HVICs) in India?

9. Which space agency’s Perseverance rover recently detected electrical activity in Mars’ atmosphere for the first time?
[A] National Aeronautics and Space Administration (NASA)
[B] European Space Agency (ESA)
[C] Japan Aerospace Exploration Agency (JAXA)
[D] Indian Space Research Organisation (ISRO)

NASA’s Perseverance Rover recently detected electrical activity in the Martian atmosphere for the first time, marking a major scientific breakthrough. Perseverance, also called “Percy”, is part of the Mars 2020 Mission. It landed in 2021 inside the ancient river delta of Jezero Crater. Its main goal is to search for signs of past life and collect rock and soil samples for future return to Earth. It can detect organic matter, study minerals, map chemical composition, and closely observe distant terrain. It is the first rover to record sounds on Mars and send them back to Earth.
10. Which institute has developed a new method to improve water-splitting catalysts for clean hydrogen production?
[A] Council of Scientific and Industrial Research (CSIR)
[B] Centre for Nano and Soft Matter Sciences, Bengaluru
[C] Bhabha Atomic Research Centre, Mumbai
[D] Indian Institute of Science (IISc), Bengaluru
Show Answer
Correct Answer: B [Centre for Nano and Soft Matter Sciences, Bengaluru]
Notes:
Scientists at the Centre for Nano and Soft Matter Sciences (CeNS), Bengaluru develop a new method to improve water-splitting catalysts for clean hydrogen production. The key problem addressed is the slow Oxygen Evolution Reaction (OER) compared to the Hydrogen Evolution Reaction (HER). They work on Coordination Polymers (COPs), made of metal ions and organic molecules, used in electrolysis. Coordination Polymers (COPs) normally show low activity because water blocks their active reaction sites. The team applies argon plasma treatment to create coordinatively unsaturated metal sites. This sharply improves the electrocatalytic performance without damaging structure.
