  1. Buccal Mucosa Cancer (BMC): Recently, a study highlighted that even low levels of alcohol consumption significantly increase the risk of Buccal Mucosa Cancer (BMC), a particularly common and aggressive oral cancer in India, contributing to the country’s rising cancer burden.
  • About Buccal Mucosa Cancer: A type of oral malignancy that arises from the inner cheek lining, medically known as the buccal mucosa.
  • The cancer typically develops from squamous epithelial cells, which form the surface lining of the mouth. As a result, the majority of BMC cases are classified as Squamous Cell Carcinoma (SCC).
  • It represents the most common oral cancer subtype in the Indian subcontinent, largely due to lifestyle-related risk factors.
  • Tobacco consumption (smoked or chewed) and alcohol use are the leading contributors, as they trigger abnormal cellular changes in cheek tissues.
  • Common warning signs include non-healing ulcers, localized swelling or lumps, pain, restricted mouth movement, and difficulty in chewing.
  • Management strategies depend on disease progression and may involve surgical removal, radiotherapy, chemotherapy, or a combination of these treatments.
  • Timely diagnosis plays a critical role in improving treatment outcomes and long-term survival.
  • Overall, the five-year survival rate for oral cavity cancers, including buccal mucosa cancer, is estimated to be around 60–70%, with better outcomes in early-stage detection.
  1. PRAGATI: Recently, at the Fifth National Conference of Chief Secretaries, states were urged to replicate PRAGATI and adopt technology-driven, outcome-oriented cooperative federalism.
  • About PRAGATI: Launched in 2015, PRAGATI stands for Pro-Active Governance and Timely Implementation

  1. Shipbuilding Schemes: Recently, the Ministry of Ports, Shipping and Waterways (MoPSW) released operational guidelines for two flagship initiatives to boost India’s shipbuilding sector—the Shipbuilding Financial Assistance Scheme (SBFAS) and the Shipbuilding Development Scheme (SbDS).
  • About SBFAS: The scheme seeks to boost indigenous shipbuilding, reduce dependence on imports, and enhance India’s competitiveness in the global maritime industry.
  • Key Features: The government will extend assistance covering 15% to 25% of the vessel cost, varying with the type and category of ship.
  • Support is structured on a graded basis for small, large, and specialised vessels, with payments released in phases linked to project milestones and secured through financial guarantees.
  • About SbDS: The scheme is designed for long-term development of infrastructure, technology, and human capital in the shipbuilding ecosystem.
  • Key Features: It supports the creation of new greenfield shipbuilding clusters and the modernisation and expansion of existing brownfield shipyards.
  • Will receive 100% capital funding for shared maritime and internal infrastructure through a Centre–State Special Purpose Vehicle (SPV) with equal participation.
  • The scheme includes a government-backed Credit Risk Coverage Framework to insure against pre-shipment risks, post-shipment risks, and supplier defaults, improving investor confidence.
  1. Passenger Assistance Control Room (PACR): Recently, the Ministry of Civil Aviation (MoCA) established a 24×7 Passenger Assistance Control Room (PACR) to ensure faster, coordinated, and passenger-centric grievance redressal.
  • About PACR: Objective: To create a centralised, real-time and coordinated mechanism addressing passenger-centric aviation issues and crisis situations.
  • Operational Oversight: PACR operates round-the-clock, continuously monitoring aviation operations, passenger complaints and service disruptions.
  • Technology Integration: The AirSewa grievance portal is fully integrated, supported by an omni-channel system and data-driven dashboards for live tracking of complaints.
  • On-the-Spot Resolution: Physical presence of airline representatives enables immediate coordination and faster resolution of passenger issues.
  • Priority Issues Addressed: Flight delays, cancellations, refunds, baggage problems and congestion-related complaints, as per the Passenger Charter.
  • Passenger-Centric Vision: Guided by principles of Passenger First, Collaborative Action, Stakeholder Convergence and Technology-driven governance.
  • Impact: Significant improvement in speed, transparency and effectiveness of passenger grievance resolution, receiving positive passenger feedback.
  1. Chronic Obstructive Pulmonary Disease (COPD): Recently, amid worsening air quality in Delhi-NCR, experts warned that air pollution more than smoking is driving a silent Chronic Obstructive Pulmonary Disease (COPD) epidemic in India, posing a long-term public health threat.
  • About COPD: A lung disorder marked by persistent breathing difficulty due to long-term damage to the lungs. This damage involves inflammation and scarring, which may affect the airways, the air sacs (alveoli), or both.
  • Causes: Smoking is the leading cause of COPD, while prolonged exposure to indoor air pollution is another major contributor.
  • Types of COPD: Chronic bronchitis: Caused by inflammation of the airway lining (bronchi). The inflamed airways narrow, restricting airflow and leading to excess production of thick mucus.
  • Emphysema: Occurs when the alveoli are damaged, reducing the lungs’ ability to transfer sufficient oxygen into the bloodstream and resulting in breathlessness.
  • Symptoms of COPD: Persistent cough with mucus lasting three months or longer
  • Chest tightness, Shortness of breath, especially during physical activity
  • Wheezing or whistling sounds while breathing
  • Recurrent chest infections and ongoing fatigue
  1. Decision Support System (DSS): Recently, the Delhi Government announced a proposed collaboration with IIT Kanpur to develop an AI-enabled Decision Support System (DSS) to combat air pollution through real-time data, hyperlocal source identification, and measurable outcomes.
  • Key Highlights: Real-time & hyperlocal monitoring: Focus on sensor-based monitoring, real-time data, and hyperlocal source apportionment.
  • Granular source identification: System will identify pollution sources like dust, transport, industry, biomass burning, and regional factors.
  • Targeted interventions: Shift from blanket bans to hotspot-specific, evidence-based actions.
  • Dynamic source apportionment: Scientific assessment of sector-wise contribution to PM2.5 pollution.
  • 365-day pollution strategy: Pollution control to be continuous, not seasonal; integrated tech–governance–enforcement approach.
  • Forecasting gaps: AQEWS predicted only 1/15 severe AQI (>400) episodes in 2023–24; improved to 5/14 in 2024–25.
  • Ongoing enforcement actions: Inspections at construction sites, large-scale road sweeping, and thousands of vehicular pollution challans issued.
  1. Frequency Comb: Recently, a frequency comb has emerged as a revolutionary laser-based tool enabling ultra-precise measurement and comparison of light frequencies, transforming scientific precision measurement.
  • About Frequency Comb: A unique type of laser whose spectrum consists of evenly spaced lines, resembling the teeth of a comb. Unlike conventional lasers that emit a single colour, it produces a wide range of precisely separated frequencies.
  • The spacing between these frequencies is exceptionally regular and highly stable.
  • Frequency combs are typically generated using mode-locked lasers that release ultra-short pulses of light at a constant repetition rate.
  • They make it possible to compare an unknown light frequency with a very stable reference standard.
  • When light from the frequency comb and an unknown source strike the same detector, their interaction produces measurable electrical signals due to interference.
  • By studying these signals, scientists can accurately determine the exact frequency of the unknown light.
  • As a result, frequency combs provide unprecedented precision in optical measurements.
  • They are widely used in advanced applications such as calibrating atomic clocks and detecting gravitational effects on light.
  1. Rare-Earth Elements (REEs): Recently, the global push towards clean energy, electric mobility, and advanced electronics has elevated rare-earth elements to strategic importance, intensifying competition despite their relative abundance in the earth’s crust.
  • About REEs: These are 17 metallic elements—15 lanthanides plus scandium and yttrium.
  • Names of all rare-earth elements: Scandium, Yttrium, Lanthanum, Cerium, Praseodymium, Neodymium, Promethium, Samarium, Europium, Gadolinium, Terbium, Dysprosium, Holmium, Erbium, Thulium, Ytterbium, Lutetium.
  • Location in periodic table: Lanthanides appear as a separate row below the main table; scandium and yttrium lie in Group 3.
  • Historical naming: Called “rare earths” because they were first identified as oxide (‘earth’) powders and rarely found as pure metals.
  • Technological importance: REEs have unique magnetic, optical, and electrical properties due to their 4f electrons.
  • Permanent magnets: Neodymium-iron-boron magnets are extremely strong and essential for EVs, wind turbines, motors, generators.
  • Optics & lighting: Europium and terbium used in phosphors; neodymium and erbium in lasers and fibre optics.
  • Other uses: Catalysts, glass, ceramics, polishing powders, and specialised industrial materials.
