Current Affairs Quiz - May 2025

Notes:
Jal Shakti Minister C R Paatil held a review meeting on 30 April with the Wildlife Institute of India to assess the progress of the ‘Jalaj’ project. The ‘Jalaj’ project is a key initiative developed by the Ministry of Jal Shakti to support the rejuvenation of the Ganga River and biodiversity conservation. It involves setting up floating platforms on the Ganga River to promote livelihood activities for local communities. These platforms also raise awareness about conserving the river and its ecosystem. The project blends ecological restoration with sustainable development for Ganga-dependent populations.

Notes:
A new project called SeaCURE has begun on the south coast of England to remove carbon dioxide from the sea. The SeaCURE project is an initiative of the United Kingdom (UK) government. The SeaCURE project is testing if taking carbon directly from seawater can be a low-cost and large-scale way to cut down carbon dioxide in the air. This method is different from usual carbon capture techniques that focus on emissions at their source or pull carbon dioxide from the air. SeaCURE targets the ocean, where carbon levels are up to 150 times higher than in the atmosphere.

Notes:
The government has revamped the National Security Advisory Board (NSAB) after the Pahalgam terror attack, appointing former intelligence chief Alok Joshi as chairman. National Security Advisory Board (NSAB) is an advisory body under the National Security Council (NSC) structure. It is chaired by the Prime Minister, supported by the National Security Advisor (NSA) and the National Security Council Secretariat (NSCS). Established in 1998 after the Pokhran-II nuclear tests, it institutionalized India’s national security framework. The NSAB provides non-partisan strategic inputs on national security issues but is not a decision-making body. It reports to the NSCS and includes experts from various sectors.

Notes:
Every year on May 3, World Press Freedom Day is celebrated to highlight the vital role of the media, known as the fourth pillar of democracy. The day spreads awareness about the struggles faced by journalists and supports the free flow of information. It honours media professionals who have risked or lost their lives in search of truth. This year’s theme is ‘Reporting In The Brave New World – The Impact Of Artificial Intelligence On Press Freedom And The Media.’ The day was established by the United Nations General Assembly (UNGA) in 1993 after a 1991 recommendation by UNESCO.

Notes:
Tunnel No. 8 (T-8) is set to become India’s longest railway tunnel at 14.57 km, overtaking Tunnel No. 50 (T-50), which is 12.77 km long on the Udhampur-Srinagar-Baramulla Railway Link. It is part of the Rishikesh–Karnaprayag Broad Gauge Rail Link Project in Uttarakhand. T-8 is a twin tunnel located on the Devprayag–Janasu stretch of this 125-km rail line. The Rishikesh–Karnaprayag Broad Gauge Rail Link Project is being implemented by Rail Vikas Nigam Limited (RVNL), a Navratna Public Sector Undertaking under the Ministry of Railways.

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:
Coal Miners Day 2025 is observed on May 4 to recognise the vital role of coal miners in powering industries and energy systems. It honours their hard work in dangerous conditions and reminds us of their rights, health, and safety needs. The day also highlights past mining disasters and the need for better support, especially during the shift to clean energy. The Mines Act, 1952 was passed to provide medical care, safety rules, and rescue services for miners. The Coal Mines Act, 1974 aimed to conserve co

Notes:
A new mosquito species called the “Pwani molecular form” has been found in coastal areas of Tanzania and Kenya, drawing global attention to malaria control. It belongs to the Anopheles gambiae complex, which includes some of the world’s most dangerous malaria-spreading mosquitoes. This mosquito shows strong genetic differences from other species in the same group, suggesting unique behaviour or environmental adaptation. Genetic studies confirm it is only found along the coastal regions of East Africa, mainly in Tanzania and Kenya. It does not carry the usual genes for insecticide resistance found in other malaria vectors. This may mean it has a different resistance method or is more sensitive to current insecticides.
