Trade Intelligence and Analytics (TIA) Portal

Context: Union Commerce Minister Piyush Goyal launched the Trade Intelligence and Analytics (TIA) Portal to enhance transparency and data-driven decision-making in India’s trade ecosystem.

About the Trade Intelligence and Analytics (TIA) Portal

  • The Trade Intelligence and Analytics Portal is a one-stop digital platform developed by the Department of Commerce to consolidate global and bilateral trade data for analytical use.
  • Objective: The portal aims to strengthen evidence-based policymaking and empower stakeholders through accessible, integrated and automated trade intelligence tools.
  • Key Features of the TIA Portal
    • Integrated Trade Databases: The portal consolidates multiple global and bilateral databases, including UN Comtrade, into a unified analytics system.
    • Extensive Visual Analytics: It offers over 270 interactive visualisations across more than 28 dashboards covering India-level, global and bilateral trade patterns.
    • Trade Watch Tower: It provides country and commodity-level intelligence and identifies champion products by mapping global demand with India’s supply capabilities.
    • Automated Workflows: Monthly Trade Reports, surge reports and data extraction processes are automated, reducing manual effort and ensuring real-time accessibility.
    • Specialised Dashboards: The portal includes dashboards for Production Linked Initiative (PLI) commodities, critical minerals, surge monitoring, and market diversification, with tariff analysis tools under development.
    • Advanced Trade Indices: Tools such as Trade Complementarity, Revealed Comparative Advantage and Trade Intensity Index support deeper competitiveness and market assessments.
    • Open-Source, Cost-Efficient Model: The platform operates on an open-source framework with minimal server costs, ensuring scalability and long-term sustainability.

 

Kodaikanal Solar Observatory (KSO)

Context: Using 100+ years of Kodaikanal Solar Observatory solar data, scientists have reconstructed the Sun’s past polar magnetic behaviour to improve future solar-cycle predictions.

Key Findings of KSO

  • Century-long Magnetic Reconstruction: Historical Ca II K images enabled mapping of polar magnetic fields before direct measurements began in the 1970s.
    • Ca II K images are images of the Sun taken in the specific ultraviolet light of the Calcium II K-line at a wavelength of 393.4 nm.
    • These images show the Sun’s chromosphere, revealing magnetic structures like plages, network regions, and fibrils that are not visible in white-light images
  • Polar Network Identified: Feature-recognition algorithms detected bright “polar network” structures that reliably indicate past polar field strength.
  • Global Data Integration: KSO archives were combined with Rome-PSPT observations to generate a continuous, high-quality solar magnetic dataset.

About Solar Cycle

  • The solar cycle refers to the periodic rise and fall in the Sun’s magnetic activity, reflected in variations in sunspots, solar flares, and coronal mass ejections.
    • Period: The solar cycle lasts about 11 years on average.
  • A full magnetic cycle (polarity reversal and return to original) takes approximately 22 years.
  • Phases of the Solar Cycle
    • Solar Minimum: Few sunspots, low solar activity.
    • Solar Maximum: Peak sunspot numbers, frequent flares and CMEs.
  • Magnetic Field Reversal: Occurs around the maximum, when the Sun’s north and south magnetic poles flip.
  • Key Features
    • Driven by the Sun’s magnetic dynamo mechanism.
    • Tracked using sunspot counts and solar irradiance variations.
    • Influences solar wind, radiation levels, and interplanetary magnetic field.

Significance of Findings on Solar Magnetic data

  • Better Solar Cycle Forecasting: Strengthens predictions for Solar Cycle 25 and future cycles.
  • Enhanced Space-Weather Alerts: Supports early warning of solar storms affecting satellites and power systems.
  • Open Scientific Access: Public release of PNI data advances global heliophysics research.

About Kodaikanal Solar Observatory (KSO)

  • Kodaikanal Solar Observatory (KSO), established on 1 April 1899  is a premier solar observatory operated by the Indian Institute of Astrophysics (IIA) under the Department of Science & Technology.
  • Location: Situated in the Palani Hills, Tamil Nadu, offering ideal atmospheric conditions for solar observations.
  • Features
    • Extensive Archives: Over 200,000 glass plates and century-long Ca II K solar records.
    • Solar Telescopes: Includes H-alpha telescope, twin telescopes, and WARM telescope.
    • Scientific Instruments: Spectrograph, photoheliograph, full-disc spectroheliographs, and radio spectrograph.

 

enFnCas9

Context: India has advanced its gene-therapy capabilities through a major collaboration between CSIR-IGIB and the Serum Institute of India to scale the indigenous enFnCas9 platform.

About enFnCas9

  • enFnCas9 is an engineered high-fidelity CRISPR-Cas9 genome-editing system designed for precise and efficient correction of genetic mutations.
  • Developed By: CSIR–Institute of Genomics and Integrative Biology (CSIR-IGIB) as part of India’s indigenous CRISPR technology initiatives.
  • Built on IGIB’s expertise, including earlier breakthroughs like FELUDA, India’s first CRISPR-based COVID-19 diagnostic.
  • It is Suitable for both ex vivo (cell-based) and in vivo (direct delivery) gene therapy approaches.

About Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR):

  • CRISPR is a natural immune system found in bacteria that allows them to defend against viruses by cutting foreign DNA. 
  • Scientists have adapted this system for gene editing, allowing precise changes to DNA in living organisms.
  • Key Components
    • CRISPR sequences: Repeated DNA segments in bacteria that store viral signatures.
    • Cas proteins (like Cas9): Molecular “scissors” that cut DNA at targeted locations.
    • Guide RNA: Directs Cas9 to the exact DNA sequence that needs to be edited.

Significance of indigenous enFnCas9

  • Advances Indigenous Gene Therapy: Demonstrates India’s capability in developing high-precision, home-grown CRISPR technologies like enFnCas9, reducing dependence on foreign platforms.
  • Addresses High-Burden Diseases: Enables affordable gene-editing therapies for conditions such as sickle cell disease, especially among vulnerable tribal populations.
  • Boosts Biomanufacturing Capacity: Leverages Serum Institute’s global-scale production to translate laboratory innovations into mass-deployable therapies.
