Akashvani – The Sound of India
The Akashvani (All India Radio)

What It Is?

»     Akashvani (officially known as All India Radio) is India’s premier national public radio broadcaster. Operating as one of the two main wings of Prasar Bharati (an autonomous statutory corporation, with Doordarshan being its television counterpart), it is one of the largest multi-lingual and multi-cultural broadcasting networks in the world.

Established In:

»     Formal Launch: Officially named All India Radio (AIR) on June 8, 1936, after originating as the experimental Indian State Broadcasting Service (ISBS) on April 1, 1930.

»     The Name “Akashvani”: Formally adopted as the official on-air name for the national broadcaster in 1956, drawing from a Bengali poem written by Nobel laureate Rabindranath Tagore in 1938 for the inauguration of Kolkata’s shortwave transmission.

History of the Broadcaster:

»     Enthusiast Origins: Broadcasting began in India in June 1923 with private transmissions by the Radio Club of Bombay, followed by the Calcutta Radio Club.

»     The Colonial Era & ISBS: The private Indian Broadcasting Company (IBC) was set up in 1927 but faced liquidation by 1930. The British colonial government then stepped in, establishing the Indian State Broadcasting Service (ISBS).

»     The BBC Blueprint: In August 1935, Lionel Fielden, a senior producer from the BBC, was appointed as India’s first Controller of Broadcasting, providing professional structure to the network before its official transition to All India Radio in 1936.

»     Independence Day Baseline: At the time of India’s independence in 1947, the country was left with just six radio stations, covering barely 2.5% of the country’s area and 11% of the population.

»     The Classical Preservation Era: In 1952, Information and Broadcasting Minister B. V. Keskar revolutionized programming by prioritizing Indian classical arts on the airwaves, establishing the iconic annual Akashvani Sangeet Sammelan in 1954 to provide a national stage for maestros like Pandit Ravi Shankar and Ustad Bismillah Khan.

»     Autonomy Milestone: Following recommendations from the Chanda and Verghese committees, the Indian Parliament enacted the Prasar Bharati Act, which came into effect in November 1997, liberating Akashvani from direct ministry control into an autonomous public service corporation.

Key Features:

»     Vast Reach: Today, Akashvani operates over 460 radio stations across the country, making it accessible to virtually the entire Indian population and covering 92% of the country’s geographic area.

»     Unparalleled Language Footprint: Broadcasts programs in 23 official languages and 146 native dialects, serving an extraordinarily diverse audience.

»     News Services Division (NSD): Operates a 24×7 news network broadcasting over 600 daily news bulletins in home, regional, and external services, backed by 46 Regional News Units (RNUs).

»     Vividh Bharati: Launched in 1957, this service remains one of India’s most popular commercial entertainment channels, broadcast over specialized FM Gold and FM Rainbow channels.

»     External Services Division (ESD): Broadcasts daily in 27 languages (15 foreign and 12 Indian) reaching out to listeners across more than 100 countries, acting as a soft-power tool for public diplomacy.

Four Pillars of India’s Energy Security

the Indian National Science Academy (INSA)—specifically through its Centre for Science, Technology, Innovation and Policy—released a milestone policy brief highlighting the urgent need for a unified national energy framework.

A unified policy architecture for India’s energy future

What it is?

»     The proposed unified policy architecture is an integrated national framework designed to shift energy planning away from fragmented, sector-specific silos into a cohesive ecosystem.

»     By building national governance around four key pillars—Adequacy, Access, Affordability, and Appropriate Sustainability—the architecture seeks to match aggressive economic growth with environmental safety and resource efficiency.

Key Data and Facts on India’s Energy Transition:

»     Massive Renewable Scaling: India’s installed renewable energy capacity grew more than sixfold over a decade, rising from approximately 40 GW in 2015 to nearly 260 GW by 2025.

»     The Strategic Deadlines: The architecture is anchored to two milestone years: achieving complete energy self-reliance by 2047 and reaching absolute net-zero carbon emissions by 2070.

»     Subsidizing Cognitive Shifts: Moving past material outlays, the framework complements evolving national goals like the National Green Hydrogen Mission, which is backed by a ₹19,744 crore central allocation to catalyze clean energy infrastructure.

The Imperative Need for a Unified Energy Architecture:

»     Breaking Departmental Silos: India’s energy governance is traditionally split across separate, disconnected ministries, which limits long-term strategic planning.

»     Managing Escalating Economic Demand: Ongoing industrialization, rapid urbanization, and population growth require a highly coordinated supply grid to prevent localized deficits.

»     Mitigating High Hydrocarbon Import Reliance: India remains dependent on foreign imports for a massive share of its crude oil and natural gas requirements, leaving the economy vulnerable to geopolitical price shocks.

»     Balancing Grid Intermittency: As solar and wind capacities cross the 260 GW baseline, the grid requires tight integration between variable generation, modern transmission networks, and electrical storage systems.

»     Avoiding Rigid One-Size-Fits-All Models: The country requires region-specific transition pathways that protect fossil-fuel-dependent workforce communities while deploying localized bio-resources and clean fuels.

Key Initiatives Taken So Far:

»     The Saubhagya Scheme: A massive rural and urban utility program that successfully delivered near-universal household electricity access across the country.

»     Pradhan Mantri Ujjwala Yojana: A major social welfare initiative that expanded access to clean cooking fuel (LPG), improving indoor air quality for millions of economically vulnerable households.

»     The National Green Hydrogen Mission: A comprehensive technological and financial roadmap launched to establish India as a leading global production hub and exporter of green hydrogen.

»     Deploying Advanced Pilot Frameworks: The establishment of cutting-edge research installations, such as NTPC’s 150 tonnes-per-day Green Urea pilot plant at Pudimadaka, demonstrates the active deployment of Carbon Capture, Utilization, and Storage (CCUS) technologies.

Key Challenges Associated with the Energy Framework:

»     High Infrastructure Retrofitting Costs: Upgrading existing coal-fired thermal utilities and local distribution grids to safely manage variable renewable loads requires immense capital spending.

»     Synchronizing Real-Time Storage Technology: Scaling up high-capacity battery storage systems and run-of-the-river hydropower to manage energy distribution during non-peak solar hours remains technically challenging.

»     Navigating Intricate Federal Coordination: Finalizing uniform utility laws requires tight policy alignment between the central government and fiscally stretched state electricity boards.

»     High Costs of Deep-Water and Specialized Logistics: Transporting captured industrial carbon dioxide or shifting hydrogen feedstocks requires a specialized pipeline and storage infrastructure network.

»     Managing Early-Stage Green Premiums: Emerging alternatives like green hydrogen and green ammonia remain significantly more expensive to manufacture than traditional fossil-fuel-derived equivalents.

Way Forward:

»     Enacting a Phased, Decade-Long Strategy: Deploy a step-by-step transition plan focused on infrastructure strengthening and green hydrogen scaling in the near term, before moving toward deep industrial decarbonization.

»     Integrating Cross-Cutting CCUS Technologies: Connect heavy industrial sectors like steel, cement, and thermal power directly with Carbon Capture, Utilization, and Storage networks to commercialize waste gas emissions.

»     Diversifying the National Energy Storage Portfolio: Scale up grid-level battery storage, small hydro schemes, and pump-storage installations to ensure 24/7 power supply stability.

»     Fostering Public-Private Green Technology Partnerships: Work with global technology leaders and local innovators to manufacture high-efficiency electrolyzers and solar components domestically, lowering production costs.

»     Enforcing Portable Welfare and Community Protections: Create targeted skilling and transition funds to retrain fossil-fuel workforces, ensuring that regional transitions are fair and inclusive.

Conclusion:

The INSA policy brief emphasizes that India’s long-term energy security depends on treating its power grid as an integrated whole rather than an accumulation of separate fuel markets. By anchoring national development to the four pillars of adequacy, access, affordability, and appropriate sustainability, the proposed framework provides a practical plan to safely phase down carbon emissions.

Gait Analysis in Crime and Medicine

During the high-profile investigation into the Ketan Agarwal murder case at Lohagad Fort, a Pune court extended the police custody of the accused to allow investigators to conduct a forensic gait analysis.

Gait Analysis

What It Is?

»     Gait analysis is the systematic and scientific study of human locomotion—specifically how an individual walks, hops, or runs.

»     It involves a detailed biomechanical breakdown of how the nervous system coordinates continuously with bones, muscles, and joints to move the body forward, producing a highly distinct “biomechanical signature” for every individual.

How It Works?

The basic unit of measurement is the gait cycle, which tracks the series of structural movements from the exact moment one foot strikes the ground until that same foot touches the ground again. The cycle is split into two primary operational phases:

»     The Stance Phase (Approx. 60% of the cycle): Begins with a heel strike and ends when the toe pushes off. In this phase, the foot is in firm contact with the surface, absorbing shock while supporting the body’s full weight.

»     The Swing Phase (Approx. 40% of the cycle): Occurs when the foot leaves the ground and swings forward to prepare for the next step. The body shifts focus to ensure the toes clear the floor without dragging.

Key Parameters of Gait Analysis:

»     Spatial Parameters:Measures step length, stride length, walking base width, and toe angle to assess balance, posture, and walking symmetry.

»     Temporal Parameters: Records cadence (steps/minute), walking speed, and double-support time to evaluate gait rhythm, stability, and movement efficiency.

»     Full-Body Systemic Tracking (Sheffield Tool):Analyses a 15-point body movement pattern, including head, shoulders, arms, torso, hips, knees, and feet for complete gait assessment.

»     Modern Instrumentation: Uses high-speed cameras, pressure mats, force plates, and wearable motion sensors to accurately capture movement and walking mechanics.

Primary Applications

»     Forensic Investigations & Criminology: Helps identify suspects from CCTV footage by analysing unique walking patterns such as limps, stride length, or body posture when facial identification is unavailable.

»     Clinical Diagnosis & Healthcare: Assists in diagnosing Parkinson’s disease, stroke, cerebral palsy, dementia, orthopedic disorders, and monitoring rehabilitation through gait abnormalities.

»     Sports Biomechanics & Performance: Enables athletes to improve running efficiency, reduce injury risk, optimize movement mechanics, and design customized footwear through gait analysis.

Schizothorax pelzami: Endangered Jewel of Himalayan Streams

The indigenous Sangno clan of Arunachal Pradesh has launched a community-led translocation drive in the East Kameng district to conserve the endangered Himalayan ray-finned fish (Schizothorax pelzami).

The Himalayan Ray-Finned Fish

What It Is?

»     The Himalayan ray-finned fish (Schizothorax pelzami), commonly known as the Transcaspian marinka and locally called Ngarsing in the Nyishi language, is a specialized freshwater species belonging to the carp and minnow family (Cyprinidae).

»     It falls under the infraclass Teleostei (modern bony fishes) and represents the evolutionary culmination of structural traits engineered for high-altitude aquatic survival.

Habitat and Distribution:

»     Geographic Range: Native to the high-altitude, fast-flowing mountain streams, rivers, and cold-water torrents of the sub-Himalayan and Transcaspian zones.

»     Micro-Habitat: Thrives in clean, well-oxygenated, snow-fed glacial streams at high elevations—such as the Lapabung and Richaso streams in the eastern Himalayas, sitting thousands of feet above sea level.

»     Ecosystem Dynamics: Shares river systems with larger predators like the aggressive, fast-swimming Mahseer (known as the ‘tiger of the water’), requiring shallow or isolated upland streams to breed safely.

Conservation Status:

»     IUCN Red List Status: Classified globally as Endangered.

Key Features:

»     Bony Ray-Finned Architecture: The fins are supported by flexible bony rays, providing better balance, steering, and stability while swimming in fast-flowing mountain streams.

»     True Homocercal Tail: The tail has equal upper and lower lobes, generating balanced thrust that improves swimming speed and efficient forward movement.

»     Mobile Jaw Mechanics: Its protractile (extendable) mouth helps suck algae and small aquatic organisms from rocks and riverbeds, supporting efficient feeding.

»     Overlapping Scale Layering: Thin, overlapping scales reduce body weight and water resistance, allowing greater agility and energy-efficient swimming.

Significance:

»     Schizothorax species are highly sensitive to water quality, temperature, and oxygen levels, making them reliable indicators of Himalayan river health.

»     Conservation by the Nyishi community through temporary fishing bans protects fish populations while preserving traditional livelihoods and promoting eco-tourism.

Siang River at the Crossroads

The proposed ₹113,000 crore Siang Upper Multipurpose Project (SUMP) remains locked in a tense standoff with local indigenous Adi and Galo tribes in Arunachal Pradesh over displacement concerns and a deep trust deficit.

Siang Upper Multipurpose Project

What It Is?

»     The Siang Upper Multipurpose Project (SUMP) is a planned mega-hydroelectric and flood-control facility designed with an installed capacity of 11,000 MW to 11,200 MW.

»     It consolidates two earlier proposals into a single, massive storage-type reservoir with an estimated height of 280–300 meters, engineered to generate 47 billion kWh of electricity annually and hold a massive 9-billion-cubic-meter reservoir volume.

Location and Rivers Involved:

»     Location: Planned near Geku village in the Upper Siang district of Arunachal Pradesh, India.

»     Primary River: The Siang River, which enters India near Gelling. Upstream in Tibet, the river is known as the Yarlung Tsangpo (originating at an elevation of 5,300 meters in the Chemayungdung mountain range near Mansarovar).

»     Basin Confluences: The Siang flows 197 km to its confluence with its largest right-bank tributary, the Shiyomi River, before joining the Dibang and Lohit downstream in Assam to form the mighty Brahmaputra River.

• The basin is also fed by the high-altitude Yar Gyap Chu stream flowing through the Mechuka Valley.

Current Status:

»     The project is currently stalled.

»     Intense grassroots protests led by the Siang Indigenous Farmer’s Forum (SIFF) and the Adi Banne Kebang (ABK) have blocked the executing agency, NHPC, from conducting essential pre-feasibility surveys.

»     On-the-ground resistance covers three proposed coordinates—Ugeng, Dite Dime, and Parong—leaving the exact scope of village submergence and displacement highly contested.

Key Features:

»     Deep Canyon Topography: The Siang flows through the Yarlung Tsangpo Grand Canyon, creating steep, fast-flowing gorges that provide immense hydropower potential but remain ecologically fragile.

»     Fragile Seismotectonic Zone: The basin lies in the earthquake-prone eastern Himalayas, where landslides and seismic activity can trigger natural dams and sudden downstream floods.

»     Alluvial Valleys and Agriculture: Downstream alluvial plains are rich in fertile sediments, supporting the region’s orchard economy with crops like kiwi, mandarin oranges, and large cardamom.

»     Volatile Monsoonal Hydrology: Heavy monsoon rainfall causes sharp seasonal flow variations, leading to floods, riverbank erosion, and loss of fertile agricultural land.

Significance:

»     Developing infrastructure on the Siang strengthens India’s prior-use claims under international water law, reinforcing its position in transboundary river management.

»     The proposed reservoir can absorb sudden flood surges or upstream water releases, reducing flood risks for Arunachal Pradesh and Assam.

»     The project can generate clean hydropower, improve irrigation, create employment, and transform Arunachal Pradesh into a major green energy hub.
