Current Affairs Quiz – September 2025

Notes:
The Kaushalya Dam is located near Pinjore in Haryana on the Kaushalya river, a tributary of Ghaggar. It plays a vital role in flood management and water storage in the Ghaggar basin; Haryana is the only state with such a dam on this river.

Notes:
Tirupati Urban Development Authority (TUDA) has launched Operation SWARNA (Swarnamukhi Waterbody Action for River and Nala Awareness). The plan aims to rescue Swarnamukhi River from land grabbers, revive its flow area and rejuvenate it for long-term sustenance. Swarnamukhi River is an east-flowing river in Andhra Pradesh with a catchment area of 3,225 sq.km. It originates near Pakala village, Chittoor district at 300 m elevation in the Eastern Ghats. The river runs 130 km northeast, passing through Tirupati hills before joining the Bay of Bengal. Swarnamukhi is an independent river system, relying mainly on rainfall in its upper catchment for flow.

Notes:
Odisha’s Debrigarh Wildlife Sanctuary received National Tiger Conservation Authority (NTCA) approval in 2025 to become India’s newest tiger reserve. Debrigarh Wildlife Sanctuary is located in Bargarh district, Odisha. It is situated near Hirakud Dam on the Mahanadi River, the longest dam in India and the longest earthen dam in the world. The sanctuary covers an area of nearly 347 sq km. Debrigarh holds historical significance due to freedom fighter Veer Surendra Sai.

Notes:
Israel launched its new spy satellite “Ofek-19” into orbit on September 2, 2025. The launch took place from Palmachim Airbase in Israel. Ofek-19 is a Synthetic Aperture Radar (SAR) satellite with advanced surveillance abilities. It successfully entered orbit, transmitted first data, and cleared all initial tests. The satellite can capture high-resolution images day and night in all weather. It can detect objects smaller than 50 cm, improving intelligence accuracy. The launch boosts Israel’s regional intelligence and defense capabilities.

Notes:
India’s largest Lithium-ion (Li-ion) battery manufacturing plant was inaugurated in Haryana on 5 September 2025. When fully operational, it will produce 20 crore battery packs annually, meeting nearly 40% of India’s 50 crore pack requirement. The plant was set up under the Centre’s Electronics Manufacturing Cluster (EMC) scheme. Li-ion batteries are rechargeable, with lithium ions moving between graphite (negative electrode) and lithium metal oxides (positive electrode) through a non-aqueous electrolyte. They offer high energy density (75-200 Wh/kg), are lightweight, use fewer toxic metals, and provide good cycle stability and efficiency. They have low self-discharge and no memory effect, ensuring reliable performance.

Notes:
Anand V. Patil has been honoured with Prof. V.K. Gokak Award. The award ceremony is held in Bengaluru on September 7 2025. The award is named after Prof. Vinayaka Krishna Gokak, a prominent Indian literary figure. It recognises individuals with significant contributions to Indian literature, especially in the Kannada language. The award highlights the importance of promoting regional literature and nurturing young readers. Anand V. Patil’s recognition reflects his lasting impact on children’s literary culture in India.

Notes:
Researchers at S. N. Bose National Centre for Basic Sciences (SNBNCBS) discovered protein p47’s new role as a “mechanical chaperone.” P47 is a cofactor protein known for assisting p97 in protein trafficking, degradation, and membrane fusion. Study revealed p47 boosts mechanical efficiency of protein extraction from endoplasmic reticulum (ER) to cytoplasm. It stabilizes polypeptides under stress, guides them through pores, prevents misfolding, and improves translocation. This is the first single-molecule evidence of autonomous, force-dependent chaperone-like activity by p47. Discovery opens new therapeutic possibilities for diseases linked to protein instability.

Notes:
Ukraine unveiled the FP-5 “Flamingo,” a new long-range cruise missile. It is developed by Ukraine’s Fire Point defense company. The missile has a range of 3,000 kilometres and carries a 1,150-kilogram warhead with a maximum takeoff weight of 6,000 kg. Flamingo is the first indigenously produced “heavy” missile in Ukraine’s arsenal. It has a wingspan of six meters and uses a turbofan engine. The missile can reach speeds up to 900 km/h and navigates using inertial systems and GPS. Its high terminal velocity and heavy warhead allow deeper target penetration and greater destruction. It is designed to resist electronic warfare, likely with secure GPS and CRPA antennas.

Notes:
World Duchenne Awareness Day (WDAD) is observed every year on September 7. It raises awareness about Duchenne Muscular Dystrophy (DMD), a rare progressive genetic disorder. DMD causes muscle weakness and wasting, eventually affecting breathing and heart function. The 2025 theme is “Family: the heart of care.”The 2025 theme is “Family: the heart of care,” highlighting family’s role in supporting people with Duchenne and Becker Muscular Dystrophy (DMD/BMD). Becker Muscular Dystrophy (BMD) is a milder form of DMD. WDAD 2025 will feature a global documentary showing families’ resilience and caregiving journeys. The day promotes awareness, education, advocacy, and inclusion for people living with dystrophinopathies.

Notes:
Bharatiya Janata Yuva Morcha (BJYM) launched the ‘Namo Yuva Run’ to mark PM Narendra Modi’s 75th birthday on September 17. The nationwide run will be held on September 21 across 75 cities in India. More than 1 million youths are expected to participate in the campaign. The event promotes fitness and a drug-free India as its twin messages.
