1. ‘BRAIN-EATING AMOEBA’ CASES SEE SURGE IN KERALA WHAT HAPPENED Kerala has reported a sharp rise in infections caused by the free-living amoeba Naegleria fowleri, popularly called the "brain-eating amoeba". The state has recorded 26 cases and 17 deaths in the first half of 2025. CORE ISSUE The infection is rare but highly fatal. Rising temperatures, stagnant water bodies, and improved surveillance are contributing to increased detection. KEY DETAILS • Disease caused by Naegleria fowleri, which leads to Primary Amoebic Meningoencephalitis (PAM). • Amoeba enters the body through the nose during swimming or diving in contaminated freshwater. • It does not spread from person to person. • Symptoms include fever, headache, vomiting, seizures, and rapid neurological deterioration. • Kerala accounts for most reported cases in India; cases have also emerged in other states. • State has introduced mandatory reporting and strengthened surveillance. • India recorded its first survivor in 2024 after treatment at AIIMS Delhi. • Climate change, warming water bodies, and poor water quality are increasing concerns globally. WHY IT MATTERS The rise in PAM cases highlights the growing public-health risks associated with climate change and water quality. It also underscores the need for disease surveillance, public awareness, and safe recreational water management. 2. WHY AN ASSAM–NAGALAND PACT RAISES HOPES OF HIGHER OIL & GAS OUTPUT FROM NORTHEAST WHAT HAPPENED The Centre, Assam, and Nagaland signed a Memorandum of Understanding (MoU) to facilitate oil and gas exploration in the long-disputed Disputed Area Belt (DAB) along their border. CORE ISSUE Decades-old inter-state boundary disputes had stalled exploration despite the region's significant hydrocarbon potential. KEY DETAILS • The Disputed Area Belt (DAB) lies along the Assam–Nagaland border. • Oil and gas exploration remained suspended in parts of the area for nearly three decades. • The MoU creates a coordinated framework involving the Union Home Ministry and both state governments. • The agreement does not settle the boundary dispute but enables resource exploration. • Assam contributes about 15% of India's crude oil production. • The Northeast is one of India's oldest hydrocarbon-producing regions. • Increased domestic production aligns with efforts to reduce import dependence. • Exploration will be undertaken while maintaining law and order and local stakeholder consultations. WHY IT MATTERS India imports over 85% of its crude oil needs. Unlocking hydrocarbon reserves in the Northeast can strengthen energy security, attract investment, and boost economic development in the region.

Pre & Mains Notes

1. EASY PILL TO SWALLOW: NEW ORAL GLP-1 DRUG SHOWS ENCOURAGING RESULTS DURING TRIALS WHAT HAPPENED A clinical trial of ecolecglipron, an experimental oral GLP-1 drug, showed significant reductions in blood sugar levels and body weight among Type-2 diabetes patients, raising hopes for a convenient alternative to injectable therapies. CORE ISSUE Current GLP-1 drugs are largely injectable and often inconvenient. An effective oral version could improve treatment adherence and diabetes management. KEY DETAILS • GLP-1 drugs mimic gut hormones that regulate blood sugar and appetite. • Ecolecglipron is a once-daily oral GLP-1 receptor agonist with no food or water restrictions. • Phase-2 trial involved 406 participants across multiple countries. • Up to 89.6% of participants achieved HbA1c below 7%, a key diabetes-control target. • Participants also recorded significant weight loss over 26 weeks. • Particularly relevant for India, which has over 100 million diabetes patients. • India's "thin-fat phenotype" (high visceral fat despite lower BMI) increases metabolic risks. • Larger Phase-3 trials are required before regulatory approval. WHY IT MATTERS India faces a rapidly growing diabetes burden. An affordable and convenient oral therapy could improve treatment compliance, reduce complications, and strengthen long-term diabetes management. 2. EC RULES ON COCKROACH AS A SYMBOL Following public attention around the proposed "Cockroach Janata Party", questions arose over whether a political party can obtain a cockroach as its election symbol under Election Commission rules. CORE ISSUE Election symbols are regulated to ensure uniformity, voter recognition, and fairness in the electoral process. KEY DETAILS • Election symbols are governed by the Election Symbols (Reservation and Allotment) Order, 1968. • Recognised National and State Parties receive reserved symbols (e.g., BJP's Lotus, Congress's Hand). • Unrecognised parties and independent candidates choose from a list of free symbols notified by the Election Commission. • The latest free-symbol list (2025) contains 184 symbols. • Symbols include everyday objects such as balloons, dustbins, frying pans, fruits, etc. • Since the 1990s, the EC has generally avoided allotting animal symbols following concerns raised by animal welfare groups. • Therefore, a cockroach symbol is unlikely to be allotted under current practice. • Authority of the EC flows from Article 324 of the Constitution, which vests it with the superintendence and conduct of elections. WHY IT MATTERS Election symbols play a crucial role in India's electoral democracy, especially for voters with limited literacy. The issue highlights the EC's regulatory powers and the importance of maintaining a clear and recognisable symbol system.

Pre & Mains Notes

1. CONGESTION, RESOURCES, RULES: WHY RESIDENTIAL AREAS ARE MORE VULNERABLE TO FIRE WHAT HAPPENED A major fire in Delhi's Malviya Nagar has renewed concerns about fire safety in residential areas. Despite an overall decline in fire incidents, homes continue to account for the largest share of fire-related deaths in India. CORE ISSUE Weak enforcement of building norms, lack of fire-safety infrastructure, and unplanned urbanisation make residential buildings particularly vulnerable to fires. KEY DETAILS • Around 60% of fire-related deaths in 2024 occurred in residential buildings. • Many residential structures lack smoke alarms, fire suppression systems, evacuation plans, and Fire NOCs. • Common causes: short circuits and gas leaks. • Fire services are a State subject; municipalities handle fire services under Article 243W and the 12th Schedule. • The National Building Code (NBC) 2016 provides fire-safety standards, including smoke management and evacuation norms. • Rapid urbanisation, narrow access roads, and illegal building modifications worsen risks. • The 15th Finance Commission recommended ₹5,000 crore for strengthening fire services. • Urban fires are recognised as a major disaster risk in the UN Global Assessment Report (2018). WHY IT MATTERS Fire safety is an important urban governance issue linked to planning, disaster management, and public safety. As Indian cities become denser and more vertical, stronger enforcement of safety norms and better-equipped fire services become critical. 2. THE POWER OF MANGROVES OVER SEAWALLS WHAT HAPPENED The article argues that India relies heavily on engineered coastal protections like seawalls, while ecosystem-based solutions such as mangroves, seagrasses, and coral reefs remain underutilised despite their proven effectiveness. CORE ISSUE Nature-based coastal adaptation offers long-term resilience but receives less policy attention and funding than conventional infrastructure. KEY DETAILS • Ecosystem-based Adaptation (EbA) uses biodiversity and ecosystem services to reduce climate risks. • Mangroves, seagrass meadows, coral reefs, and wetlands act as natural buffers against cyclones, erosion, and storm surges. • Cyclone Dana highlighted the protective role of Bhitarkanika's mangroves. • India has over 11,000 km of coastline exposed to climate risks such as sea-level rise and cyclones. • States spent heavily on seawalls and embankments, while funding for ecosystem-based adaptation remains limited. • Mangroves also support fisheries, livelihoods, carbon sequestration, and biodiversity conservation. • Relevant initiatives include MISHTI (Mangrove Initiative for Shoreline Habitats & Tangible Incomes) launched in Budget 2023-24. • Supports India's commitments under climate adaptation and disaster-resilience frameworks. WHY IT MATTERS Nature-based solutions are often cheaper, more sustainable, and provide multiple ecological benefits. Mainstreaming EbA can strengthen coastal resilience while simultaneously supporting livelihoods and biodiversity conservation. 3. UNDERSTANDING SPF NUMBER ON SUNSCREEN LOTION AND HOW IT IS MEASURED WHAT HAPPENED The article explains what Sun Protection Factor (SPF) measures, how sunscreen effectiveness is assessed, and why higher SPF numbers do not necessarily mean proportionately better protection. CORE ISSUE Consumers often misunderstand SPF ratings and ignore factors such as UVA protection, proper application, and reapplication. KEY DETAILS • SPF measures protection against UVB radiation, which primarily causes sunburn. • SPF 30 blocks roughly 95–97% of UVB rays; SPF 50 blocks about 97–98%. • Protection gains increase only marginally at higher SPF levels. • SPF does not measure UVA protection, which contributes to skin ageing and skin cancer risks. • Experts recommend broad-spectrum sunscreens with SPF and UVA protection (PA rating). • Sunscreen should be applied 15–20 minutes before exposure and reapplied every 2–3 hours.

• Water-resistant formulations are preferable for outdoor activities. • No sunscreen blocks 100% of UV radiation. WHY IT MATTERS Rising temperatures and increased UV exposure make sun protection a public health concern. Scientific awareness about sunscreen use can reduce skin damage, premature ageing, and long-term skin cancer risks.

Pre & Mains Notes

1. IS CLIMATE RESEARCH BEING HELD BACK BY LOCAL INSTRUMENTATION? WHAT HAPPENED Mega Science Vision-2035 flagged India's heavy dependence on imported climate research instruments and stressed the need for indigenous scientific equipment to improve research quality and self-reliance. CORE ISSUE India can develop prototypes but struggles to commercialise scientific instruments, creating technological dependence. KEY DETAILS • Report prepared under the Principal Scientific Adviser (PSA). • India imports most advanced climate-monitoring instruments. • Lack of indigenous manufacturing affects calibration, maintenance and data reliability. • Recommends preference for domestic instruments in public procurement. • Calls for Climate & Health Observatory and expanded climate modelling capacity. • Supports carbon-pricing based on the Polluter Pays Principle. • Linked to India's climate targets, including 500 GW non-fossil capacity by 2030. • Relevant to Atmanirbhar Bharat in high-technology sectors. WHY IT MATTERS Climate research underpins weather forecasting, disaster management and climate policy. Indigenous scientific infrastructure improves strategic autonomy, reduces import dependence and strengthens India's climate resilience. 2. HORMUZ TO NUCLEAR ISSUE: RUBIO'S TESTIMONY TEMPERS EXPECTATIONS WHAT HAPPENED US Secretary of State Marco Rubio cautioned that significant gaps remain in Iran nuclear negotiations and broader West Asia ceasefire efforts despite ongoing diplomatic engagement. CORE ISSUE The Iran nuclear issue intersects with regional security, energy markets and global geopolitics. KEY DETAILS • Iran continues negotiations over limits on its nuclear programme. • JCPOA (2015) aimed to restrict Iran's nuclear activities; US exited in 2018. • IAEA monitors Iran's nuclear facilities. • Strait of Hormuz carries nearly one-fifth of global oil trade. • Any disruption can sharply increase crude oil prices. • China has emerged as an important diplomatic actor in West Asia. • US sanctions and waivers on Russian oil remain relevant for India. • Chabahar Port and INSTC make Iran strategically important for India. WHY IT MATTERS Developments in Iran and the Strait of Hormuz directly affect India's energy security, trade routes and diplomatic interests. Stability in West Asia remains critical for global oil markets and regional peace.
