2. The European Red Admiral butterfly (Vanessa atalanta) was recently spotted in which Indian state?
[A] Uttarakhand
[B] Uttar Pradesh
[C] Himachal Pradesh
[D] Punjab
[B] Uttar Pradesh
[C] Himachal Pradesh
[D] Punjab
Correct Answer: C [Himachal Pradesh]
Notes:
The European Red Admiral butterfly, scientifically called Vanessa atalanta, has been recorded for the first time in India near Dharamshala, Himachal Pradesh. This rare sighting was confirmed during a butterfly survey at Thatharna Hill in the Dhauladhar mountain range, at an altitude of 2,500 metres. The observation was verified by Himalayan butterfly expert Lovish Garlani from the Himachal Pradesh Forest Department. This raises the total number of butterfly species in Himachal Pradesh to 440, highlighting the region’s rich biodiversity. The species is known for long migrations across Europe and North America and was last seen in South Asia in 2022 in Pakistan after a 93-year gap. It has no confirmed records from China, Mongolia, or Afghanistan, making its presence in India a significant eastward range expansion.

5. 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
[B] University of Tokyo
[C] Indian Institute of Science (IISc), Bengaluru
[D] None of the Above
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.

[C] European Space Agency (ESA)
[D] None of the Above
Correct Answer: A [National Aeronautics and Space Administration (NASA)]
Notes:
Scientists from the University of Oxford have suggested a new way to monitor volcanic eruptions using a method called shear-wave splitting. Shear-wave splitting happens when seismic waves travel at different speeds depending on their direction, especially through rocks with tiny cracks. This technique was studied at Mount Ontake in Japan, which is an active stratovolcano located on Honshū Island, near Tokyo. Mount Ontake is Japan’s second-highest volcano and lies in the Pacific Ring of Fire.

7. What kind of disease is MASH (Metabolic Dysfunction-Associated Steatohepatitis) that was recently seen in news?
[A] A genetic brain disorder
[B] An autoimmune skin condition
[C] A serious form of fatty liver disease
[D] A bacterial lung infection
[B] An autoimmune skin condition
[C] A serious form of fatty liver disease
[D] A bacterial lung infection
Correct Answer: C [A serious form of fatty liver disease]
Notes:
A recent study in the New England Journal of Medicine found that a weekly dose of semaglutide shows strong results in treating Metabolic Dysfunction-Associated Steatohepatitis (MASH). Semaglutide is a Glucagon-Like Peptide-1 (GLP-1) receptor agonist, first developed to treat Type 2 diabetes. It is the main ingredient in medicines like Ozempic, used for diabetes, and Wegovy, used for weight loss. MASH is a severe type of fatty liver disease caused by metabolic problems and not by alcohol. It involves fat buildup, inflammation, and liver scarring, and is linked to obesity, diabetes, and overnutrition. If not treated, MASH can lead to cirrhosis or liver failure.

8. Alcatraz Island, that was recently seen in news, is located in which country?
[A] United States
[B] France
[C] Australia
[D] China
[B] France
[C] Australia
[D] China
Correct Answer: A [United States]
Notes:
Recently, the US President instructed his administration to rebuild and expand Alcatraz, the notorious prison that has been closed for over 60 years on an isolated island off California’s coast. Alcatraz Island, also known as “The Rock,” is a rocky landmass in San Francisco Bay, United States. In 1849, the island was sold to the U.S. government and became home to the first California lighthouse in 1854. By 1859, the first permanent army troops were stationed there, and in 1861, it became a military prison. In 1934, Alcatraz became a federal prison, housing some of the most dangerous criminals. The prison had the capacity to hold over 330 prisoners, but typically housed around 260 at a time. Known as the most inescapable prison in the United States, it operated as a maximum-security facility until 1963.

Notes:
The Department of Biotechnology (DBT) has recently released detailed data, infographics, and graphical summaries on over 100 bacterial genomes under the ‘One Day One Genome’ initiative. A genome is the complete genetic material of an organism, made of unique DNA (Deoxyribonucleic Acid) or RNA (Ribonucleic Acid) sequences. These sequences are made of chemical units called nucleotide bases, and identifying their order is known as genomic sequencing. The ‘One Day One Genome’ initiative was launched in November 2024 by Department of Biotechnology (DBT) and Biotechnology Research and Innovation Council (BRIC). It is coordinated by BRIC-National Institute of Biomedical Genomics (NIBMG), West Bengal. Data contributions come from 13 BRIC institutions and two bodies: International Centre for Genetic Engineering and Biotechnology (ICGEB), New Delhi, and Regional Centre for Biotechnology (RCB), Faridabad.
