1. According to the new study, which medication may be more effective than aspirin for long-term prevention of heart attacks?
[A] Metformin
[B] Clopidogrel
[C] Ibuprofen
[D] Heparin
Show Answer
Correct Answer: B [Clopidogrel]
Notes:
For decades, aspirin was the main drug to prevent heart attacks and strokes. A new study presented at the European Society of Cardiology congress and published in The Lancet shows clopidogrel, a blood-thinning antiplatelet drug, may be more effective. Review of seven clinical trials with 29,000 coronary artery disease patients found clopidogrel 14% more effective than aspirin in lowering major cardiovascular risks. Importantly, there was no higher risk of serious bleeding compared to aspirin. Clopidogrel (a P2Y₁₂ inhibitor) works by blocking platelet receptors to stop dangerous blood clots. It is low-cost, widely available, and safe, making it a strong candidate to replace aspirin in treatment guidelines.

[B] Chandrayaan 3201
[C] Bhaskara 3201
[D] Vikram 3201
Show Answer
Correct Answer: D [Vikram 3201]
Notes:
India unveiled its first fully indigenous 32-bit microprocessor, Vikram 3201, at Semicon India 2025. It is designed by Vikram Sarabhai Space Center (VSSC) and fabricated by Indian Space Research Organisation’s (ISRO) Semiconductor Laboratory (SCL), Chandigarh. Vikram 3201 is designed specifically for rockets and satellites, unlike processors in smartphones or laptops. It is an upgrade of Vikram 1601, a 16-bit processor used in ISRO launch vehicles since 2009. The processor manages navigation, control, and mission management in launch vehicles. The launch supports India’s semiconductor self-reliance, with five units under construction under the Design-Linked Incentive scheme.
4. Researchers have found evidence that interstellar dust grains align with magnetic fields in the Milky Way. Interstellar dust grains are composed of which materials?
[A] Iron and nickel
[B] Silicates and carbonaceous material
[C] Hydrogen and helium
[D] Oxygen and nitrogen
Show Answer
Correct Answer: B [Silicates and carbonaceous material]
Notes:
Scientists have found that tiny interstellar dust grains act as storytellers of the universe. A team led by the Indian Institute of Astrophysics (IIA), Bengaluru, provided the strongest observational evidence of how these dust grains align with magnetic fields in the Milky Way. Dust grains are a few micrometers in size, made of silicates and carbonaceous material, and exist throughout the interstellar medium. They play a key role in star and planet formation and cause starlight polarization detected since 1949.
5. Melioidosis, the disease responsible for the public health emergency in Turakapalem village of Andhra Pradesh, is caused by which pathogen?
[A] Fungus
[B] Bacteria
[C] Fungus
[D] Protozoa
Show Answer
Correct Answer: B [Bacteria]
Notes:
Turakapalem village in Guntur, Andhra Pradesh, has seen 29 deaths due to Melioidosis. It is caused by the Gram-negative bacterium Burkholderia pseudomallei found in soil and water. The government has declared a public health emergency in the area. The disease is seasonal, with 75–85% of cases during the rainy season. It has a high case fatality rate (CFR) of 16% to 50% in endemic regions. Endemic areas include Southeast Asia, northern Australia, Indian subcontinent, southern China, Hong Kong, and Taiwan. Currently, no vaccine is available, but early diagnosis and treatment are crucial.
6. Which institute conducted the first successful wheat cultivation experiment in the Thar desert using ‘soilification’ technology?
[A] Banaras Hindu University
[B] Punjab Agricultural University
[C] Central Soil Salinity Research Institute
[D] Central University of Rajasthan
Show Answer
Correct Answer: D [Central University of Rajasthan]
Notes:
Recently, Central University of Rajasthan (CUoR) conducted the first successful wheat cultivation in arid land using desert ‘soilification’ technology. The experiment aims to stop the expansion of western Rajasthan’s Thar desert towards the National Capital Region. Desert sand was converted into soil using polymers and indigenous bioformulation, enhancing water retention and soil structure. The project was supported by Krishi Vigyan Kendra (KVK) and the State Horticulture Department. The experiment proves that even barren desert land can become productive with biotechnology.
7. What is the name of India’s first space astronomy observatory which recently completed 10 years of operation?
[A] AstroSat
[B] Chandrayaan
[C] INSAT-3C
[D] Vikram
Show Answer
Correct Answer: A [AstroSat]
Notes:
India’s first dedicated space astronomy observatory, AstroSat, completed 10 years of operation on 28 September 2025. It was launched on 28 September 2015 by PSLV-C30 (Polar Satellite Launch Vehicle-C30) XL from Satish Dhawan Space Centre, Sriharikota. Though designed for 5 years, it continues to provide valuable data after a decade. AstroSat studies the universe across multi-wavelengths: UV (Ultraviolet), Visible, Low and High Energy X-rays. It was developed by ISRO (Indian Space Research Organisation) with collaboration from Indian institutes and partners from Canada and the UK.
8. Infectious Bovine Rhinotracheitis (IBR) disease, 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:
Indian Immunologicals Limited (IIL) has launched India’s first indigenously developed glycoprotein E (gE) deleted DIVA (Differentiated between Infected and Vaccinated Animal) marker vaccine against Infectious Bovine Rhinotracheitis (IBR) in Anand, Gujarat. IBR is caused by Bovine Herpes Virus-1 (BHV-1), belonging to the genus Varicellovirus under Alphaherpesvirinae subfamily. It mainly affects domestic and wild cattle. The disease has three forms – respiratory, genital and encephalitic, with respiratory and genital being common. Transmission occurs through aerosols and semen from bulls to milch animals, impacting the reproductive system.
9. 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.
10. What is the primary objective of NASA’s Cassini mission?
[A] To study Jupiter’s atmosphere
[B] To explore Saturn and its moons
[C] To map the surface of Mars
[D] To study Moon’s atmosphere
Show Answer
Correct Answer: B [To explore Saturn and its moons]
Notes:
A new analysis of NASA’s Cassini spacecraft data shows that Saturn’s moon Enceladus may support life. Cassini was a joint mission of NASA, European Space Agency (ESA), and Italian Space Agency (ASI). It was launched on October 15, 1997, to study Saturn and its moons in detail. The mission had NASA’s Cassini orbiter and ESA’s Huygens probe, which landed on Titan, Saturn’s largest moon. Cassini studied Saturn’s atmosphere, rings, and magnetosphere, along with Titan’s surface and atmosphere. It provided key insights into Saturn’s cloud properties, ring composition, and planetary evolution.
