3. Which country has launched a global campaign titled ‘Preventing Future Encephalitis: Climate Change and Infectious Disease’?
[A] United States
[B] France
[C] United Kingdom
[D] India
Show Answer
Correct Answer: C [United Kingdom]
Notes:
United Kingdom (UK)-based health charity Encephalitis International has launched a global campaign titled ‘Preventing Future Encephalitis: Climate Change and Infectious Disease’ to raise awareness about encephalitis and promote vaccination. Encephalitis is the inflammation of active brain tissues caused by infections or autoimmune responses, affecting over 1.5 million people globally every year. The campaign highlights how climate change increases encephalitis risk by creating conditions for disease-carrying vectors like mosquitoes and ticks to spread. India is among high-burden countries, with 1,548 cases of Japanese encephalitis reported in 2024 from 24 states and union territories.
4. What does the cosmological parameter S8 (Sigma Eight) primarily measure?
[A] The temperature of stars
[B] The “clumpiness” or clustering of matter in the universe
[C] The expansion rate of the universe
[D] None of the Above
Show Answer
Correct Answer: B [The “clumpiness” or clustering of matter in the universe]
Notes:
The Subaru Telescope in Hawaii recently used the Hyper Suprime-Cam to carry out a deep sky survey from the University of Tokyo. It reported a Sigma Eight (S8) value of 0.747, which matches earlier results from gravitational lensing studies. Sigma Eight (S8) is a key measure in cosmology that shows how matter is clustered or “clumpy” across the universe on a scale of 26 million light-years. It tells scientists how much visible and dark matter is gathered in different parts of space. This finding helps us understand how the universe evolved from a smooth early state after the Big Bang.

[D] Sameer Verma and Parupalli Kashyap
Show Answer
Correct Answer: B [Satwiksairaj Rankireddy and Chirag Shetty]
Notes:
Satwiksairaj Rankireddy and Chirag Shetty recently received the Major Dhyan Chand Khel Ratna Award for their outstanding achievements in badminton. The pair reached the No. 1 rank in the Badminton World Federation rankings in 2023 and won the Asian Games gold medal in Hangzhou. The Major Dhyan Chand Khel Ratna Award was originally established as the Rajiv Gandhi Khel Ratna in 1991–92 and renamed in 2021. It is India’s highest sporting honour, given for the most exceptional performance by a sportsperson over the last four years. Only performances in recognized international events are eligible for consideration. The award includes a ₹25 lakh cash prize, a medal, and a certificate of honour, with typically one award given each year.
6. Chandola Lake, which was seen in news, is located in which state?
[A] Gujarat
[B] Rajasthan
[C] Odisha
[D] Haryana
Show Answer
Correct Answer: A [Gujarat]
Notes:
The Gujarat High Court recently upheld a demolition drive carried out by state authorities in Ahmedabad’s Chandola Lake area. Chandola Lake, located in Ahmedabad, Gujarat, is an artificial lake established by Tajn Khan Nari Ali, the wife of a Mughal Sultan. Covering an area of approximately 1,200 hectares, the lake serves as a key water source for nearby industrial and residential areas. It has a circular shape and is divided into two parts, Chota Chandola and Bada Chandola. The Kharicut Canal Scheme, one of Gujarat’s oldest irrigation schemes, was introduced to irrigate 1,200 acres of rice land near the lake. The lake is home to various bird species, including cormorants, painted storks, and spoonbills.
7. Kendu leaf, also known as Tendu leaf is referred to as the Green Gold of which Indian state?
[A] Odisha
[B] Jharkhand
[C] Bihar
[D] Gujarat
Show Answer
Correct Answer: A [Odisha]
Notes:
Eight Gram Sabhas in Baipariguda block, Koraput district, Odisha, have harvested over 4 lakh bundles of kendu leaves in the 2025 season and are waiting for government notification to deregulate the trade. These communities are pushing to manage and sell kendu leaves under the Forest Rights Act (FRA), 2006. Kendu leaf, also known as Tendu leaf, is a vital non-wood forest product and is referred to as the “Green Gold of Odisha.” It is a major forest product in states like Madhya Pradesh, Chhattisgarh, Odisha, and others. Under the FRA, forest-dwelling communities have rights to collect, use, and sell minor forest products like kendu leaves.
8. Which institution has recently reported the first-ever experimental observation of a two-dimensional layered room-temperature altermagnet?
[A] Hong Kong University of Science and Technology (HKUST)
[B] University of Tokyo
[C] Indian Institute of Science (IISc), Bengaluru
[D] None of the Above
Show Answer
Correct Answer: A [Hong Kong University of Science and Technology (HKUST)]
Notes:
A research team from the Hong Kong University of Science and Technology (HKUST) has made the first-ever experimental observation of a two-dimensional layered altermagnet at room temperature. Altermagnets are a new class of antiferromagnetic materials that show momentum-dependent spin splitting without needing spin–orbit coupling (SOC) or overall magnetization. This spin splitting is caused by exchange interactions between magnetic sublattices connected by crystal symmetry, known as C-paired spin-valley locking (SVL). Altermagnets combine the stable spin properties of antiferromagnets with spin-split energy bands, making them promising for next-generation spintronic devices.
9. Which is the nodal ministry for implementing the SVAMITVA scheme?
[A] Ministry of Urban Development
[B] Ministry of Panchayati Raj
[C] Ministry of Rural Development
[D] Ministry of Agriculture
Show Answer
Correct Answer: B [Ministry of Panchayati Raj]
Notes:
India’s SVAMITVA scheme will be highlighted at the World Bank Land Conference in Washington, D.C., showcasing its role in digitalising rural land records. SVAMITVA stands for Survey of Villages and Mapping with Improvised Technology in Village Areas and was launched in 2020 as a central sector scheme. It aims to give rural residents legal documents for their residential properties to help them access loans and other financial services. Drone technology is used to survey land parcels in rural inhabited areas across India in phases. The scheme helps bring financial stability to rural citizens by treating property as a financial asset. It also ensures accurate land records for better rural planning and governance. The Ministry of Panchayati Raj (MoPR) is the nodal ministry for implementing the scheme. State Revenue or Land Records Departments implement the scheme with support from State Panchayati Raj Departments.
10. Ghassem Basir Ballistic Missile has been developed by which country?
[A] Iraq
[B] Iran
[C] Saudi Arabia
[D] Israel
Show Answer
Correct Answer: B [Iran]
Notes:
Iran recently unveiled a new solid-fuel ballistic missile named Ghassem Basir. It is a Medium-Range Ballistic Missile (MRBM) developed to strike targets over 1,200 kilometers away. The missile is about 11 meters long and weighs around 7 tons. It uses carbon fiber composite material for its body, making it lighter and harder to detect by radar. It runs on solid fuel, making it quicker to launch and easier to store than liquid-fuel missiles. It can reach speeds up to Mach 12. A thermal imaging sensor helps it track targets using heat in the final phase of flight. It has a Maneuverable Reentry Vehicle (MaRV) that detaches mid-flight to avoid radar and improve accuracy. It can be launched from mobile Transporter-Erector-Launchers (TELs), even from vehicles that look like civilian trucks.
