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.

6. 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

7. 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.

8. 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.

9. 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.
