Current Affairs Quiz - May 2025

Notes:
Under the Swachh Bharat Mission-Urban, Ghaziabad issued India’s first Certified Green Municipal Bond, raising ₹150 crore for a Tertiary Sewage Treatment Plant (TSTP). This bond marks a major shift towards sustainable urban infrastructure and financial innovation. The Tertiary Sewage Treatment Plant uses advanced Membrane Filtration Technologies like microfiltration, ultrafiltration, nanofiltration, and reverse osmosis (RO) to treat wastewater. The plant has a treatment capacity of 40 Million Litres per Day (MLD) and is linked to a 95 km pipeline network. It supplies treated water to over 1,400 industrial units, cutting dependence on freshwater sources.

Notes:
A rare inscription from the time of Vikramaditya I of the Badami Chalukya dynasty was recently found at Madapura Lake in Davangere district, Karnataka. Vikramaditya I ruled from 644 Common Era (CE) to 681 CE. He became king after the defeat of his father Pulakeshin II by the Pallava king Narasimhavarman I. His most important military success was the recapture of Vatapi, the Chalukya capital, from the Pallavas. He supported temple architecture and encouraged the construction of freestanding temples, a key feature of Chalukya style. The inscription offers new insights into his rule and regional history.

Notes:
The Ministry of Social Justice and Empowerment (MoSJE) and the United Nations Development Programme (UNDP) are now working together under the wastepickers component of the National Action for Mechanised Sanitation Ecosystem (NAMASTE) Scheme. UNDP is providing financial support to State Project Management Units (PMUs) to strengthen the scheme’s implementation. The NAMASTE Scheme was jointly launched by Ministry of Social Justice and Empowerment (MoSJE) and the Ministry of Housing and Urban Affairs (MoHUA) in 2023 to protect the safety and dignity of sanitation workers. Its wastepicker component was launched in 2024 with the goal to digitally profile and register 2.5 lakh wastepickers across India. It also provides health insurance under Ayushman Bharat–Pradhan Mantri Jan Arogya Yojana (PMJAY), and offers skill development training.

Notes:
NITI Aayog, along with the Institute for Competitiveness (IFC), released a report titled ‘Enhancing Micro, Small and Medium Enterprises (MSMEs) Competitiveness in India’. The report highlights reforms needed in credit access, skill development, innovation, and market linkages to boost MSMEs. Using firm-level data and Periodic Labour Force Survey (PLFS), it suggests ways to integrate MSMEs into global value chains. Focus sectors include textiles, chemicals, automotive, and food processing. Credit access improved between 2020 and 2024, yet only 19% demand was met formally by 2021, with ₹80 lakh crore unmet. The Credit Guarantee Fund Trust for Micro and Small Enterprises (CGTMSE) expanded but still needs redesign for wider impact.

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:
India has become the first country in the world to develop genome-edited rice varieties. The Indian Council of Agricultural Research (ICAR) has developed two such varieties named DRR Rice 100 (Kamla) and Pusa DST Rice. These rice varieties were developed using genome editing technology based on Clustered Regularly Interspaced Short Palindromic Repeats-CRISPR Associated Protein (CRISPR-Cas). This technology allows precise changes in the genetic material without adding any foreign DNA. Genome editing targeted the Site Directed Nuclease 1 (SDN1) and SDN2 types of genes, which are approved under India’s biosafety rules. The development was supported by the National Agricultural Science Fund (NASF), which funds strategic agricultural research.

Notes:
World Asthma Day 2025 is observed on 6th May, which is the first Tuesday of May. It is a global event organized every year by the Global Initiative for Asthma (GINA) to raise awareness about asthma. The day focuses on educating people about asthma, its triggers, and how it affects daily life. It began in 1998 during the first World Asthma Meeting in Barcelona, Spain. The theme for World Asthma Day 2025 is “Make Inhaled Treatments Accessible for ALL”. This theme highlights the urgent need for everyone with asthma to access inhaled medicines for better control. Asthma is a chronic disease where the lung airways become narrow, swollen, and produce extra mucus.

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.
