1. Kodaikanal Solar Observatory is located in which state?
[A] Andhra Pradesh
[B] Kerala
[C] Odisha
[D] Tamil Nadu
Show Answer
Correct Answer: D [Tamil Nadu]
Notes:
The Department of Posts recently released a commemorative stamp to mark the 125th anniversary of the Kodaikanal Solar Observatory (KoSO). The Kodaikanal Solar Observatory was established in 1899 by the Indian Institute of Astrophysics (IIA) in Tamil Nadu. It was set up to study the Sun and its impact on Earth’s climate, particularly on the Indian monsoon. This decision followed the Great Drought of 1875–1877, which caused a massive famine that killed nearly 50 million people globally. The Famine Commission then recommended setting up a solar observatory to explore the link between solar activity and rainfall.
2. The Minuteman III intercontinental ballistic missile (ICBM) was developed by which country?
[A] United States
[B] France
[C] Germany
[D] Russia
Show Answer
Correct Answer: A [United States]
Notes:
The United States Air Force (USAF) recently conducted a successful test of the LGM-30G Minuteman III Intercontinental Ballistic Missile (ICBM). This missile is nuclear-capable and can deliver a warhead to any part of the Earth. “L” in LGM means silo-launched, “G” stands for surface attack, and “M” means guided missile. Minuteman III was introduced in the 1970s and was the first U.S. missile with Multiple Independently Targetable Reentry Vehicles (MIRVs). It is the only land-based missile in the U.S. nuclear triad. It was developed by Douglas Aircraft Company, now part of Boeing. Although it was designed for ten years of use, it has been upgraded and remains active. A new system, called Ground-Based Strategic Deterrent (GBSD), will replace it around 2029. The U.S. currently maintains about 440 Minuteman III missiles in its arsenal.
3. What is a “bow echo” in context of meteorology?
[A] A circular cyclone formation
[B] A line of thunderstorms that curves like a bow on radar
[C] A heatwave pattern
[D] None of the Above
Show Answer
Correct Answer: B [A line of thunderstorms that curves like a bow on radar]
Notes:
Delhi recently witnessed intense storms that appeared in the shape of a crescent or archer’s bow, technically known as bow echoes. A bow echo is a line of thunderstorms that appears curved like a bow on weather radar, also called a squall line. Sometimes, this bow echo can be part of a larger squall line system. It usually stretches from 20 to 100 kilometres and lasts for three to six hours. The term bow echo was introduced in the 1970s by Ted Fujita, a meteorologist famous for creating the Fujita Scale to measure tornado intensity.
4. 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.
5. 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.
6. 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.
7. 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.
8. 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.
9. What kind of disorder is Tourette Syndrome that was recently seen in news?
[A] Autoimmune disorder
[B] Neurological disorder
[C] Cardiovascular disorder
[D] Rare genetic disorder
Show Answer
Correct Answer: B [Neurological disorder]
Notes:
Tourette Syndrome is a neurological disorder that causes sudden, involuntary movements or vocal sounds called tics. It usually starts between the ages of 2 and 15, with the average age of onset around six. It affects around 0.3% to 1% of the global population, as highlighted in recent reports. The condition is more common in boys than in girls. Tics can be mild or severe and may include blinking, jerking, or making sounds. In severe cases, it can impact speech, daily activities, and overall quality of life.
10. What is the name of India’s first agentic AI system developed by Krutrim start up?
[A] Mitra
[B] Sanchita
[C] Vaani
[D] Kruti
Show Answer
Correct Answer: D [Kruti]
Notes:
Recently, India’s first agentic Artificial Intelligence (AI) named Kruti was launched by the startup Krutrim. It is a next-generation Generative AI (GenAI) tool that goes beyond just providing information. Kruti can act independently to manage complex tasks, make decisions, and solve problems for users and organizations. It uses advanced reasoning and step-by-step planning to handle multi-layered challenges without constant human input. It processes large amounts of data from various sources to create strategies and complete tasks on its own.
