41. Which country has developed the world’s lightest brain control device to steer bees?
[A] India
[B] Russia
[C] China
[D] France
Show Answer
Correct Answer: C [China]
Notes:
Chinese researchers led by Professor Zhao Jieliang at Beijing Institute of Technology developed the world’s lightest brain control device to steer bees. It is fixed on the bee’s back with three fine needles connecting to the brain, sending signals to control direction. In trials, bees followed commands with 90% accuracy, including turning, moving forward, and reversing. The bee-based robotic model offers superior mobility, stealth, and adaptability for missions like urban combat, counterterrorism, and disaster relief.

44. Foot and Mouth Disease (FMD), that was recently seen in news, is caused by which agent?
[A] Protozoa
[B] Bacteria
[C] Fungus
[D] Virus
Show Answer
Correct Answer: D [Virus]
Notes:
Recently, 16 chitals (spotted deer) died at Rajiv Gandhi Zoological Park in Pune due to Foot and Mouth Disease (FMD), as confirmed by lab reports. Foot and Mouth Disease (FMD) is a highly contagious viral disease affecting all cloven-hoofed animals like cattle, goats, sheep, deer, and pigs. It is caused by an aphthovirus from the Picornaviridae family. The World Organisation for Animal Health (WOAH) first gave official recognition to this disease.
45. Chagas disease, that was recently seen in news, is caused by which agent?
[A] Virus
[B] Bacteria
[C] Fungus
[D] Protozoa
Show Answer
Correct Answer: D [Protozoa]
Notes:
Recently, concern was raised that despite the huge human and economic toll of Chagas disease, investment in research and development of diagnostics, medicines, and vaccines remains disproportionately low. Chagas disease, or American trypanosomiasis, is caused by the protozoan parasite Trypanosoma cruzi. It spreads mainly through blood-sucking triatomine bugs, also called reduviid or “kissing bugs,” which often bite the face. Infection occurs when parasite-containing feces of the bug enter the body. It can also spread from mother to child, contaminated food or drinks, blood transfusions, organ transplants, or lab accidents. The disease is common in South America, Central America, and Mexico.
46. Which country announced the launch of Venera-D Venus mission?
[A] Russia
[B] China
[C] United States
[D] India
Show Answer
Correct Answer: A [Russia]
Notes:
Russia announced plans to launch the Venera-D mission to revisit Venus before 2036. Preliminary design work will begin in January 2026 under the new national space programme. The mission is being developed in collaboration with the Lavochkin Association. It will include a lander, a balloon probe, and an orbital spacecraft for comprehensive study of Venus. The design phase will take two years to complete. The launch is expected between 2034 and 2036, with the exact date decided after the design phase.
47. Which organisation launched CEREBO, the portable device for rapid, radiation-free diagnosis of traumatic brain injuries?
[A] Indian Council of Medical Research
[B] Indian Red Cross Society
[C] Indian Institute of Health Management Research
[D] Ministry of Science and Technology
Show Answer
Correct Answer: A [Indian Council of Medical Research ]
Notes:
On 21 August 2025, the Indian Council of Medical Research (ICMR) launched CEREBO, a portable non-invasive device to detect traumatic brain injuries (TBI). It uses near-infrared spectroscopy with machine learning to identify intracranial bleeding and edema within one minute, giving colour-coded, radiation-free results. The device is safe for infants and pregnant women and can be operated by paramedics or unskilled staff with just 30 minutes of training. It was developed by ICMR, AIIMS Bhopal, NIMHANS Bengaluru and Bioscan Research. India records over 1 lakh deaths and 10 lakh serious head injuries annually, making early TBI detection critical.
48. 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.
49. 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.
50. Which garden was inaugurated in Lucknow at the National Botanical Research Institute (NBRI) during the CSIR Startup Conclave?
[A] Rose Garden
[B] Swastik Lotus Garden
[C] Mughal Garden
[D] Herbal Medicinal Garden

Recently, the first-of-its-kind Swastik Lotus Garden was inaugurated at the National Botanical Research Institute (NBRI), Lucknow, during the CSIR Startup Conclave. The garden features 60 lotus varieties from across the world and 50 species of water lilies. Conservation is ensured through advanced genetic methods, light regulation, and scientific treatments. CSIR technologies were transferred to private companies for public access, including perfumes Frotus-Rudra, Frotus-Kumbh, air-freshener Frotus Fresh, green firecrackers, aromatherapy oil Relaxomap, and portable water analysis kits. The initiative strengthens scientific innovation, conservation, and entrepreneurship at grassroots and national levels.
