    New GDP Series Will Not Use UPI Data

    Why in the News

    The Ministry of Statistics and Programme Implementation has decided not to use Unified Payments Interface transaction data in India’s new GDP series with base year 2022 to 23, citing instability and classification limitations.

    Why Was UPI Data Considered?

    • UPI transaction data from the National Payments Corporation of India provides:
    • Value of transactions in rupees
    • Volume of transactions
    • Merchant category codes
    • It was proposed as a non traditional indicator to estimate Private Final Consumption Expenditure (PFCE), a key component of GDP from the expenditure side.

    Why Was It Rejected?

    • Overlapping Merchant Categories: Merchant codes such as 5411 for supermarkets cover multiple product types, making it difficult to classify transactions under specific PFCE consumption heads.
    • Non Consumption Transactions Included: Certain categories like debt collection agencies do not represent household consumption but account for notable transaction value.
    • Unstable and Incomplete Data Coverage: Continued reliance on cash and ongoing digital transition mean UPI trends do not yet fully capture overall consumption patterns. The Advisory Committee suggested reconsideration once data stabilises.

    About GDP Estimation in India

    • India calculates GDP using:
      • Production or Income Approach
      • Expenditure Approach
      • PFCE forms more than half of India’s GDP.
    • Under the new series:
      • Base year updated from 2011 to 12 to 2022 to 23
      • PFCE items expanded from 46 to 128
      • Published data will cover 49 items across 13 categories

    Alternative Data Sources Being Used

    • Goods and Services Tax data
    • Vahan vehicle registration data
    • Sector specific indicators
    [2013] The national income of a country for a given period is equal to the (a) total value of goods and services produced by the nationals 

    (b) sum of total consumption and investment expenditure 

    (c) sum of personal income of all individuals 

    (d) money value of final goods and services produced

    India Among Four Nations Driving Global Pesticide Toxicity

    Why in the News

    A new study published in Science finds that India is among four countries contributing nearly 70 percent of the world’s Total Applied Toxicity (TAT) from agricultural pesticides. Experts have also raised concerns that the proposed Pesticides Management Bill 2025 may weaken safeguards compared to the older law.

    What is Total Applied Toxicity (TAT)?

    • TAT measures not just the quantity of pesticides used, but their toxicity and lethality to non target species.
    • Researchers analysed over 600 pesticides across 65 countries from 2013 to 2019.
    • Global TAT has increased, especially for around 20 commonly used agricultural pesticides.

    Countries Driving Global TAT

    • Four major contributors: China, Brazil, United States, and India
    • Together, they account for nearly 70 percent of global pesticide toxicity.
    • Only Chile is currently on track to meet the UN target of reducing pesticide risk by 50 percent by 2030.

    Impact on Biodiversity

    Species most affected:

    1. Terrestrial arthropods
    2. Soil organisms
    3. Fish
    4. Pollinators
    5. Aquatic plants
    6. Terrestrial vertebrates

    Regions with high increases include sub Saharan Africa and parts of the Indian subcontinent.

    Link to Global Commitments

    • At the 2022 United Nations Biodiversity Conference, countries committed to reducing pesticide risk by 50 percent by 2030. The findings indicate that global progress is not on track.

    Indian Legal Framework

    1. Insecticides Act 1968

    • Focused mainly on agricultural use
    • Limited regulation of domestic and non agricultural applications
    • Considered outdated
    • India reportedly uses several pesticides that are banned in parts of Europe, such as paraquat.

    2. Pesticides Management Bill 2025

    • Proposed to replace the 1968 Act
    • Aims to reduce risk to people and environment
    • Encourages biological and traditional knowledge based alternatives
    • Experts warn that without stronger liability and monitoring provisions, it may not significantly improve regulation
    [2019] In India, the use of carbofuran, methyl parathion, phorate and triazophos is viewed with apprehension. These chemicals are used as: 

    (a) pesticides in agriculture 

    (b) preservatives in processed foods 

    (c) fruit-ripening agents 

    (d) moisturising agents in cosmetics

  • Why Does Wildfire Smoke Swirl Only One Way?

    Why in the News

    Two recent studies published in Weather and Climate Dynamics and presented at the American Meteorological Society meeting explain why wildfire smoke in the stratosphere forms spinning bubbles that rotate in only one direction depending on the hemisphere.

    What Is Observed?

    • After intense wildfires, smoke can rise high into the stratosphere. Instead of dispersing immediately, it sometimes forms a compact spinning bubble called a smoke vortex.
      • Clockwise in the Northern Hemisphere
      • Counterclockwise in the Southern Hemisphere

    Why Does It Rotate Only One Way?

    • Smoke Heats the Surrounding Air: Smoke particles absorb sunlight. This warms the air around them. Warm air becomes buoyant and rises. This upward movement creates a vertical column of heated air.
    • Earth’s Rotation Effect: Because Earth rotates, moving air experiences a deflection known as the Coriolis effect
      • In the Northern Hemisphere, air is deflected to the right. In the Southern Hemisphere, air is deflected to the left. As the heated smoke rises, Earth’s rotation causes it to spin in a preferred direction.

    Why the Bubble Persists

    • The rotating vortex traps warm smoke near its centre. Reduces mixing with surrounding air.
    • Helps the bubble rise higher into the stratosphere. This mechanism is similar to how cyclones maintain structure, but on a smaller and smoke driven scale.
    [2024] With reference to “Coriolis force,” which of the following statements is/are correct? 1. It increases with increase in wind velocity. 

    2. It is maximum at the poles and is absent at the equator. 

    Select the answer using the code given below: 

    (a) 1 only  (b) 2 only  (c) Both 1 and 2  (d) Neither 1 nor 2

  • Proteins Tweaked as Quantum Sensors Inside the Body

    Why in the News

    Two recent studies published in Nature in February 2026 have demonstrated that fluorescent proteins can be genetically engineered to function as quantum sensors inside living cells, detecting magnetic fields and radio waves.

    Background

    • The discovery of Green Fluorescent Protein revolutionised biology by allowing scientists to visualise cellular processes. This breakthrough was recognised with the Nobel Prize in Chemistry in 2008.
    • Now, researchers have shown that such proteins can be modified to detect quantum level signals inside cells.

    Core Scientific Principle

    When a fluorescent protein absorbs light:

    1. An electron moves to a higher energy state.
    2. It usually returns, emitting light.
    3. In some cases, a radical pair forms with unpaired electrons.
    4. Their spin states are influenced by weak magnetic fields.
    5. Changes in spin alter fluorescence intensity.

    This is known as optically detected magnetic resonance, a quantum phenomenon.

    Key Research Findings

    1. Enhanced Yellow Fluorescent Protein

    • Exhibits a metastable triplet state
    • Spin state controlled using laser pulses and microwaves
    • Demonstrated qubit like behaviour inside cells
    • Observed in human kidney cells and in Escherichia coli at room temperature

    2. MagLOV Proteins

    • Engineered from plant light sensing proteins
    • Magneto sensitive fluorescent variants
    • Show stable magnetic resonance inside living bacterial cells
    • Genetically encodable and biologically compatible
