Current Affairs Quiz - May 2025

Notes:
India has once again been placed on the ‘priority watch’ list in the Special 301 Report by the United States Trade Representative (USTR). It is an annual review published under the Trade Act of 1974. It identifies countries that do not provide adequate and effective protection of intellectual property rights (IPRs) or fair access to US rights holders. The report has been released every year since 1989. It classifies countries as “priority foreign country”, “priority watch list”, or “watch list”. Countries on the priority watch list, like India, have serious IPR issues needing greater US attention.

Notes:
Amazon has launched the first 27 satellites under its Project Kuiper to build an internet-from-space network. Project Kuiper is Amazon’s satellite broadband initiative using Low Earth Orbit (LEO), which is up to 2,000 kilometers above Earth. It includes around 3,232 satellites, ground stations, and customer terminals to provide the service. The goal is to deliver high-speed, low-latency, and affordable internet to remote and underserved regions globally. The project is named after the Kuiper Belt, a distant region of the solar system beyond the eight planets. It is Amazon’s answer to SpaceX’s Starlink satellite internet system.

Notes:
Researchers at the Institute of Nano Science and Technology (INST), Mohali, have found a new way to improve green hydrogen production. They created a special heterostructure using Copper Tungsten Oxide and Copper Oxide. This structure uses the Built-In Electric Field (BIEF) effect to boost the Hydrogen Evolution Reaction (HER). The Copper Tungsten Oxide nanoparticles are grown over a Cu(OH)₂ base, forming a p-n heterojunction with an uneven electronic setup. This BIEF helps in better proton adsorption and desorption. Green hydrogen, made from water using clean energy, is a pollution-free fuel of the future.

Notes:
A recent study by the Global Antibiotic Research and Development Partnership (GARDP) showed that many multidrug-resistant infections in low- and middle-income countries, including India, are not being treated properly due to lack of access. GARDP is a not-for-profit organization that creates new antibiotic treatments for drug-resistant bacterial infections and ensures they reach people in need. It focuses on public health by developing antibiotics to fight the current antimicrobial resistance (AMR) crisis and protect future generations. GARDP was founded by the World Health Organization (WHO) and Drugs for Neglected Diseases initiative (DNDi) under the Global Action Plan on AMR in 2015.

Notes:
The International Monetary Fund (IMF) recently projected that global public debt may surpass the COVID-19 pandemic level of 98.9% of Gross Domestic Product (GDP) recorded in 2020. Sudan now has the highest debt-to-GDP ratio in the world at 252%, due to long-term conflict and economic struggles. Among developed countries, Japan ranks second with a debt-to-GDP ratio of 234.9%, mainly due to fiscal deficits and an ageing population. The United States ranks eighth with a ratio of 123%, while France and Canada follow with 116.3% and slightly lower respectively. China ranks 21st globally with a public debt ratio of 96%, which is lower than many advanced economies. India stands at 31st with a debt-to-GDP ratio of 80%, and the central government aims to reduce it to 50±1% by March 31, 2031.

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.

Notes:
Recently, scientists observed repeated unrest at Campi Flegrei between 1982–1984 and 2011–2024, involving land uplift, earthquakes, and underground rumbling due to rising fluid pressure. Campi Flegrei, also called the Phlegraean Fields, is an active volcanic system located near Naples, Italy. Unlike single-cone volcanoes like Mount Vesuvius, Campi Flegrei is a large caldera, which is a sunken volcanic area formed after a huge eruption. The caldera spans about 12 to 15 kilometers and was formed by a massive eruption nearly 39,000 years ago. That eruption may have triggered climate changes that contributed to the decline of Neanderthals.

Notes:
In the 2025 World Press Freedom Index by Reporters Without Borders (RSF), India ranks 151 out of 180 countries. This is a slight improvement from 159th in 2024 and 161st in 2023, but India still remains in the “very serious” press freedom category. India ranks lower than neighbours like Nepal (90th), Maldives (104th), Sri Lanka (139th), and Bangladesh (149th). Norway, Estonia, and the Netherlands are the top three performers in press freedom globally. For the first time, global press freedom is seen as in a “difficult situation” due to rising economic pressures.

Notes:
India recently halted the flow of water through the Baglihar Dam on the Chenab River, a significant move impacting water access to Pakistan. The Baglihar Dam, also known as the Baglihar Hydroelectric Power Project, is located on the Chenab River in the Doda District of Jammu and Kashmir. It features a concrete gravity dam that is 144.5 meters high and 363 meters long, with a reservoir capacity of 475 million cubic meters. The underground powerhouse of the project measures 221 meters long, 24 meters wide, and 51 meters high.

Notes:
In response to the recent terror attack in Pahalgam and rising tensions with Pakistan, the Indian Navy is enhancing its maritime strength by inducting INS Tamal. INS Tamal is a stealth guided missile frigate with advanced features designed for modern naval warfare. It is an upgraded Krivak-III class warship built under a $2.5 billion India-Russia defence deal for four stealth frigates. Two of these frigates are being built in Russia, and the other two at Goa Shipyard Limited in India. INS Tushil, the first warship of this class, joined the Indian Navy in December 2024. INS Tamal will be the last imported warship, marking India’s shift to building its own warships. The remaining two frigates, INS Triput and INS Tavasya, are being constructed in India under a technology transfer agreement worth around Rs 13,000 crore.
