    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Card-on-File Tokenisation (CoFT)

    Mains level: Not Much

    Tokenisation

    Central Idea

    • The Reserve Bank of India (RBI) has embarked on a mission to revolutionize digital payments in the country by proposing the introduction of Card-on-File Tokenisation (CoFT).
    • This move, aimed at enhancing convenience for cardholders, is set to redefine the way Indians engage in online transactions.

    Card-on-File Tokenisation (CoFT)

    • Card-on-file tokenisation involves replacing actual credit and debit card details with an alternative code known as a “token.”
    • This token is unique for a specific combination of card, token requestor, and device.
    • Each token is distinct and tailored to the combination of the card, token requestor (the entity facilitating tokenisation), and the merchant (which may or may not be the same as the token requestor).
    • The primary advantage of Card-on-File Tokenisation is enhanced security.
    • During a tokenised card transaction, the actual card details are not disclosed to the merchant.
    • This shields sensitive information from potential security breaches during transaction processing.
    • Customers who have not enabled tokenisation will need to manually input their name, 16-digit card number, expiry date, and CVV (Card Verification Value) each time they make an online purchase.

    Back2Basics: Card-on-File Transaction

    • A Card-on-File transaction occurs when cardholders authorize merchants to securely store their payment information.
    • This stored data is then used to bill the cardholders’ accounts for future purchases.
    • It simplifies the checkout process for consumers, offering convenience and efficiency.

    Novel R21/Matrix-M Vaccine

    Central Idea

    • In a momentous development in the fight against malaria, the World Health Organization (WHO) issued a recommendation for the R21/Matrix-M malaria vaccine on October 2.
    • This pioneering vaccine, developed by the University of Oxford and manufactured by India’s Serum Institute, has already gained approval for use in children under 36 months in Nigeria, Ghana, and Burkina Faso.

    R21/Matrix-M Vaccine

    • Extensive Testing: The vaccine’s efficacy was rigorously assessed in a phase-3 trial involving 4,800 children across five sites in Mali, Burkina Faso, Kenya, and Tanzania. These sites vary in malaria transmission intensity and seasonality.
    • Blind Trial: Participants were randomly assigned to receive either the malaria vaccine or a control (approved rabies vaccine) in a double-blind study, ensuring impartiality.
    • Multi-Dose Regimen: The vaccination schedule comprised three doses administered 4 weeks apart, with a booster shot administered 12 months after the last dose.
    • Strategic Timing: Primary vaccinations occurred before the malaria season in seasonal transmission regions or at any time of the year in perennial transmission regions.

    Impressive Results

    • According to preprint data (pending peer review), the vaccine demonstrated a remarkable efficacy of 75% in children aged 5-36 months in seasonal malaria regions and 68% in perennial malaria regions after one year.
    •  Notably, children aged 5-17 months, more vulnerable to severe malaria, exhibited even higher vaccine efficacy of 79% in seasonal regions and 75% in perennial regions.
    • Vaccine efficacy remained substantial for 18 months, further reinforced by a booster dose administered 12 months after the primary series.

    Seasonality Matters

    • Optimal Timing: Results suggest that the vaccine performs more effectively in regions with seasonal malaria compared to perennial transmission areas.
    • Seasonal Patterns: In seasonal sites, 82% of malaria episodes occurred in the first six months of follow-up, while only 26% occurred in the initial six months in perennial sites.
    • Vaccination Timing: Since the vaccine is administered just before the malaria season, its protection is more pronounced when malaria is seasonal.

    Atto-Physics: new tools to fathom the world of electrons

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Atto-Physics

    Mains level: NA

    Atto-Physics: the Physics behind

    Central Idea

    • The 2023 Nobel Prize in Physics was awarded to Anne L’Huillier, Pierre Agostini, and Ferenc Krausz.
    • It cited their pioneering work in attosecond science, enabling the study of electron dynamics in matter at an unprecedented timescale of one quintillionth of a second, or 10^-18 seconds.

    What is Attosecond?

    • Definition: An attosecond is a minuscule unit of time, equal to one quintillionth of a second (10^-18 seconds). It is the timescale at which electron properties change.
    • Attosecond Science: Attosecond science, or attophysics, focuses on generating ultra-short light pulses and employing them to investigate rapid processes, such as those involving electrons.

    Atto-Physics: The science behind

    • High-Harmonic Generation: Researchers, including Anne L’Huillier, discovered that passing an infrared light beam through a noble gas resulted in emitted light with frequencies that were multiples of the beam’s frequency. This phenomenon, known as high-harmonic generation, paved the way for attosecond pulse generation.
    • Wave Mechanics: Attosecond pulse production is rooted in wave mechanics. The emitted light is a consequence of electrons gaining and losing energy as they interact with oscillating electric and magnetic fields in the light beam.
    • Constructive Interference: Attosecond pulses are produced through constructive interference when peaks of different overtones merge. Destructive interference occurs when peaks align with troughs, leading to the cancellation of signals.

    Producing Attosecond Pulses

    • Interference Combinations: Researchers manipulate interference combinations of multiple overtones to generate attosecond pulses with durations of a few hundred attoseconds.
    • Precise Frequency Range: Attosecond pulses are produced when the beam’s frequency falls within a specific plateau range, as dictated by interference effects.

    Measuring Attosecond Pulses: RABBIT Technique

    • Pierre Agostini and his colleagues developed the RABBIT (Reconstruction of Attosecond Beating by Interference of Two-photon Transitions) technique.
    • It involves measuring electrons kicked out from noble gas atoms by attosecond pulses and a longer-duration pulse, providing insights into pulse properties, including duration.

    Applications of Attophysics

    • Solar Power Enhancement: Attosecond studies have refined our understanding of the photoelectric effect, a fundamental process in solar power generation. Insights gained from atto-physics could lead to improved solar technologies.
    • Electron-Dependent Fields: Attophysics impacts various scientific disciplines where electron properties play a crucial role, spanning physics, chemistry, and biology. By studying electron behavior at attosecond timescales, researchers can unlock new possibilities and applications.

    Money Bill: SC to hear challenge

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Money Bill and related provisions and procedure

    Mains level: Money Bill debate and Supreme Court in interpretations

    What’s the news?

    • In recent years, some major legislations have been passed via the money bill route. Now a seven-judge SC bench will hear a challenge to the Centre’s use of money bills for passing important laws.

    Central idea

    • In a significant development, the Chief Justice of India announced that a seven-judge bench will be constituted to address a series of pleas challenging the government’s use of the money bill route to enact certain key legislations. This move comes in response to mounting concerns about the validity and constitutional propriety of this legislative procedure.

    What is a money bill?

    • A money bill is a type of legislative proposal that is defined and governed by Article 110 of the Indian Constitution.

    What constitutes a money bill?

    • Subject: A bill is considered a money bill if it exclusively deals with specific financial matters outlined in Article 110(1)(a) to (g) of the Indian Constitution. These matters include taxation, government borrowing, and the appropriation of money from the Consolidated Fund of India, among others.
    • Introduction in Lok Sabha: Money bills can only be introduced in the Lok Sabha, which is the lower house of India’s Parliament. They cannot originate in the Rajya Sabha, which is the upper house.
    • Exclusion of Rajya Sabha Consent: Unlike ordinary bills, money bills do not require the consent or approval of the Rajya Sabha (Council of States). The Lok Sabha has the exclusive authority to pass or reject money bills.
    • Final Decision of the Speaker: Article 110(3) of the Constitution states that if any question arises whether a bill is a money bill or not, the decision of the Speaker of the Lok Sabha on this matter shall be final.
    • Judicial Scrutiny: While the Constitution grants the Speaker the final authority in deciding whether a bill is a money bill, the Indian judiciary has the power to review and examine the Speaker’s decision for compliance with constitutional provisions.

    Challenged Legislations

    • Prevention of Money Laundering Act (PMLA) Amendments:
    • In July 2022, a three-judge bench composed of Justices A. M. Khanwilkar, Dinesh Maheshwari, and CT Ravikumar upheld the PMLA and the extensive powers of the Enforcement Directorate (ED).
    • However, they left the validity of amendments to the PMLA via the Money Bill route open for review by a larger Constitution bench.
    • The Finance Acts passed in 2015, 2016, 2018, and 2019 introduced significant changes to the PMLA, raising questions about the constitutionality of their passage.
    • Aadhaar Act:
    • The Aadhaar case marked a significant challenge to the categorization of a bill as a money bill.
    • In 2018, the Supreme Court, in a 4:1 majority, ruled in favor of the government, declaring the Aadhaar Act a valid money bill under Article 110 of the Constitution.
    • Notably, Justice Chandrachud dissented, condemning the government’s action as a fraud on the Constitution and subterfuge.
    • Tribunal Reform:
    • In the case of Roger Matthew vs. Union of India in November 2019, the Supreme Court confronted the issue of changes in the service conditions of tribunal members introduced as a money bill in the Finance Act, 2017.
    • While a five-judge bench deemed the law unconstitutional for impinging on judicial independence, it referred the money bill aspect to a larger constitution bench.
    • This move also cast doubt on the correctness of the five-judge Constitution Bench’s 2018 verdict upholding the Aadhaar Act as a money bill.

    The Larger Bench and Implications

    • Constitutional Significance: The cases involve the interpretation of Article 110 and the determination of whether specific bills genuinely qualify as money bills. The decisions reached by the larger bench will establish crucial precedents in constitutional law.
    • Clarifying Legislative Boundaries: The larger bench’s decisions will play a pivotal role in clarifying the boundaries of legislative power in India. It will provide guidance on when a bill can be categorized as a money bill and, consequently, whether it requires the consent of the Rajya Sabha.
    • Impact on Challenged Legislations: The decisions of the larger bench will directly impact the validity of specific legislations challenged for being passed as money bills. For instance, in the case of amendments to the PMLA, the outcome will determine the fate of these amendments and whether they must undergo further scrutiny in both houses of Parliament.
    • Judicial Review of Speaker’s Decision: The larger bench’s deliberations may provide further clarity on the extent of judicial review over the Speaker’s decision regarding the classification of bills as money bills.

    Conclusion

    • The announcement of a seven-judge bench by CJI Chandrachud signals a substantial step toward addressing these concerns and providing clarity on the boundaries of this legislative process, which has far-reaching implications for India’s legal and political framework.
