Visa Norm Tightening

by

  • Significant Drop in US Visa Issuance: US F-1 student visas issued to Indian nationals sharply dropped by 30% in February 2025 compared to February 2024. This is disproportionately larger than the global average and other major countries like China.

  • Increased Visa Revocations: Indian nationals accounted for 50% of international students whose US visas were revoked in early 2025. The “Catch and Revoke” program is flagged as a factor, raising concerns about fairness.

  • Longer Visa Wait Times: Indian students face significantly longer visa wait times (58 days in Delhi) compared to East Asian capitals.

  • Australian Scrutiny: Australia has increased visa scrutiny for applicants from specific Indian states, leading to fears of profiling.

  • Impact on India’s Soft Power: The visa issues weaken India’s global presence and influence in key fields.

  • Risk to Demographic Dividend: Curbs hinder educational opportunities for India’s large youth population.

  • Potential Decline in Remittances: Stricter norms could reduce student migration and remittances to India.

  • Legal and Financial Hardship: Students facing revocation must undergo complex legal procedures to restore their SEVIS status

  • Human Capital Drain and Redirection: Shift towards hubs like Nordic countries and South Korea, impacting talent flow.

  • Domestic Higher Education Pressure: Strain

    Mantis Shrimp Optics

    by

    • Mantis Shrimp’s Striking Appendage as Natural Metamaterial: New research shows the mantis shrimp’s hammer-like limb (dactyl club) functions as a natural phononic metamaterial, challenging the notion that such materials are exclusive to lab creation.

    • Dual Mechanical Advantage: The club both withstands forceful impacts and controls energy propagation, providing protection from recoil.

    • Hierarchical Structure: The club’s design includes a hydroxyapatite surface for dispersing impact, spring-like tendons for shock absorption, and biopolymer fibers in a periodic pattern for reducing damage from repeated strikes.

    • Phononic Bandgap Discovery: The study revealed the internal arrangement of the microstructure serves as phononic bandgap which prevents energy waves of certain frequencies from passing through.

    • How the Mantis Shrimp Strikes:

      • Releases energy from spring-like structures.
      • Displaces water creating low-pressure zones.
      • Bubble implosions create a second blow from heat and shockwaves.

    • Impact on Material Science: The findings confirm that nature has evolved metamaterials, altering scientists’ understanding of biological material design.

    • Potential Applications:

      The research could inspire the development of synthetic sound-filtering materials for protective gear, methods for reducing blast-related injuries, and energy-harvesting applications based on trapping and converting mechanical energy.

    • Ecological and Scientific Significance: Mantis shrimp are important for controlling prey populations and nutrient cycling in reef ecosystems. Their unique

      market by bundling the Play Store with the Android TV OS and restricting alternative Android versions. This violated Section 19(1)(a) of the Competition Act, 2002.
    • CCI Findings: The CCI found Google dominant in both the Smart TV OS and App Store markets in India.
    • Settlement Terms: Google proposed a standalone license for its Play Store and Play Services for Android smart TVs, removing bundling requirements and allowing OEMs to develop non-Google Android devices.
    • Settlement Fee: Google will pay a settlement fee of ₹202.4 million (approximately $2.38 million).
    • Legal Basis: The settlement was approved under Section 48A(3) of the Competition Act, 2002, and the Competition Commission of India (Settlement) Regulations, 2024.
    • CCI’s Role: The CCI is a statutory body established in 2009 to enforce the Competition Act, 2002, aimed at preventing anti-competitive practices and promoting competition in India.
    • Impact: This settlement marks a significant resolution, potentially fostering greater competition and innovation in the Indian smart TV market.

    Carbon Market

    • ETS Defined: An Emissions Trading Scheme (ETS) is a market-based regulatory tool to reduce air pollution by incentivizing emission reductions through tradable permits. It sets a cap on total emissions.

    • How it works: Industries receive/purchase emission permits (“allowances”). Cleaner industries can sell excess

    permits to those exceeding limits. Called “cap-and-trade”.

  • Surat ETS Significance: World’s first ETS focused on particulate pollution (not CO2) and India’s first emissions market for any pollutant. Targeted 342 industries in Surat, primarily textiles.

  • Surat ETS Design: A cap on total particulate matter emissions was set and later tightened. Permits were issued, mostly for free initially, with auctions for a portion. Price floor and ceiling maintained stability.

  • Surat ETS Results: Plants under ETS reduced emissions more than those under conventional regulation, complied with permits. Non-ETS plants often failed to meet norms.

  • ETS Criticism:

    • Over-allocation of permits can keep prices low, hindering investment in cleaner tech.
    • Lobbying can delay tightening of caps.
    • Using emission intensity instead of absolute caps can be problematic.
    • Markets have sometimes disproportionately affected disadvantaged communities.

  • ETS Aim: To address monitoring and enforcement gaps in command-and-control systems by offering flexibility and incentives for compliance.
