Context:  CERN Collider Reveals Clue to Universe’s Bias Against Antimatter.

Key Finding:
For the first time, scientists have observed that the laws of physics differ between matter and antimatter in baryons (particles like protons and neutrons). This may help explain why the universe is dominated by matter despite both matter and antimatter being created in equal amounts during the Big Bang.

What Was Discovered?

• CP (Charge-Parity) violation observed in a particle called the Λb0 baryon (Lambda b zero).
• CP violation breaks the symmetry between particles and antiparticles, making them behave differently.
• This violation has been seen in mesons before, but never in baryons until now.

Experiment Details:

• Conducted by the LHCb collaboration at CERN using the Large Hadron Collider.
• Compared the decay rates of Λb0 baryons and their antimatter counterparts.
• Found a decay asymmetry of about 2.45%, with a statistical significance of 5.2 sigma (strong evidence).

Why Is This Important?

• It adds a missing piece to the puzzle of why there’s more matter than antimatter.
• Supports the idea that CP violation in baryons could have helped the universe evolve with more matter.
• Could lead to “new physics” beyond the Standard Model of particle physics.

Future Direction:

• More accurate measurement of the complex phase in baryon decays is needed.
• Researchers must determine whether the observed CP violation matches predictions or hints at unknown forces.

Historical Context:

• 1967: Physicists Sakharov, Andrei, and others proposed three conditions for matter to dominate antimatter, one of which was CP violation.
• Until now, CP violation was seen only in mesons, not in baryons.

Context: Climate Change is Fuelling Devastating Wildfires in Europe

Wildfire Situation in 2025:

• 227,000 hectares of land have burned in Europe so far this year — more than double the 20-year average.
• Not the worst year on record (2003 & 2017 saw over 1.1 million hectares burned annually).
• 1,118 fires reported till July 8, compared to 716 during the same period last year.

Role of Climate Change:

• Climate change is creating hotter and drier conditions, making wildfires more frequent and intense.
• Greenhouse gas emissions have warmed the Earth by 1.3°C since pre-industrial times.
• Europe is warming at twice the global average (WMO data).

Where are Fires Happening?

• Severe fires in Catalonia (Spain), Marseille (France), Greece (Evia and Crete), and Syria.
• Greek island fires have forced thousands to evacuate.
• Mediterranean fires have been the worst but relatively isolated.

Scientific Observations:

• Wildfires are worsened by early heatwaves and persistent dry spells.
• Once ignited, fires spread rapidly due to dry vegetation and wind.
• Climate change has caused earlier fire seasons and intensified fire behavior.

Introduction (Context)

The recent earthquakes in Myanmar, Thailand, Tibet followed by recent in Delhi, exposing the nations vulnerability to it. With earthquake activity intensifying regionally and globally, the Government of India must lead a national dialogue to enforce seismic codes rigorously.

What is Earthquake?

• Earthquake is the sudden shaking of the ground caused by the passage of seismic waves through Earth’s rocks. 
• Earth’s major earthquakes occur mainly in belts coinciding with the margins of tectonic plates.

Position of India

• India’s seismic risk arises from the northward drift of the Indian Plate, colliding with the Eurasian Plate at 4–5 cm per year
• This collision forms the Himalayas, a region overdue for a “Great Himalayan Earthquake” (magnitude 8 or higher). 
• Examples:

• • Bhuj earthquake (2001): Magnitude 7.7, over 20,000 deaths.
  • Nepal earthquake (2015): Magnitude 7.8, widespread devastation.

India’s seismic zones

According to the seismic zoning map of the country, India is divided into four seismic zones.

Zone II – Low Risk

• Characterised by low seismic activity, with earthquakes rarely exceeding magnitude 4.9.
• Covers much of southern India, including Karnataka, Tamil Nadu, Kerala, and parts of central India such as Madhya Pradesh.
• This zone faces minimal earthquake hazards compared to other regions.

Zone III – Moderate Risk

• Experiences moderate seismic activity, with earthquakes typically between magnitude 5.0 and 6.0.
• Includes regions such as:

• Western and central India, including Mumbai, Pune, and nearby areas.
• Coastal states like Andhra Pradesh and Odisha.
• Parts of the Indo-Gangetic plains, including Delhi and Bihar.

Zone IV – High Risk

• Marked by frequent and strong seismic events, generally ranging from magnitude 6.0 to 6.9.
• Major areas include:

• The Himalayan belt, covering Himachal Pradesh and Uttarakhand.
• Delhi, highlighting its significant seismic vulnerability.
• Regions in Kashmir, Punjab, and western Uttar Pradesh.

Zone V – Very High Risk

• Identified as the most seismically active zone in India, where earthquakes often reach magnitude 7.0 or above.
• Comprises:

• • The entire northeastern states, including Assam, Nagaland, Manipur, Mizoram, and Arunachal Pradesh.
  • Northern Jammu and Kashmir.
  • The Kutch region in Gujarat, known for the devastating 2001 earthquake.
  • Parts of the Andaman and Nicobar Islands, which are also prone to tsunamis due to tectonic subduction activity.

Issues in Preparedness

• Rapid urbanisation exacerbates the risk.
• Construction of buildings in liquefaction-prone soils, and poorly designed high-rises without structural retrofitting.
• Lack of public awareness 
• Poor enforcement of seismic codes. For example in the recent earthquake in Myanmar, enforced codes were not implemented which have worsened the quake toll in 2025.

Steps needed

• Rigorous enforcement of seismic codes for all new and existing structures.
• Retrofitting older buildings using steel jacketing, base isolation, and pile foundations. (Bangkok Uses high-strength concrete (30–40 MPa) and ductile detailing for earthquake resistance)
• Avoid construction on floodplains and liquefaction-prone zones. (example in Brahmaputra floodplain)
• Expand early warning systems to rural Zone V areas for timely evacuation.
• Public education campaigns on earthquake safety, kits, and drills.
• National dialogue involving urban planners, structural engineers, and local governments to mainstream seismic resilience in urban policy.
• Solutions must be tailored to regional conditions, e.g. Soft soil challenges in northeast and Sandy basin vulnerabilities in Kutch regions.
• Citizens should educate themselves about the need for emergency kits, safe building practices, and evacuation plans. The Bhuj disaster, where unpreparedness amplified casualties, remains a haunting lesson.

Conclusion

Earthquakes are inevitable natural events, but their devastation can be minimised through proactive governance, strict code enforcement, and public preparedness.

Mains Practice Question

Earthquakes are inevitable natural phenomena, but their impact on society is largely determined by human preparedness and policy measures. Discuss with reference to India’s seismic vulnerability and disaster management strategies. (250 words, 15 marks)

Introduction (Context)

Recently, the US Senate has passed the GENIUS Act, a landmark legislation that gives American banks and even large companies like Amazon and Walmart the legal green light to issue digital dollars known as stablecoins on public blockchains.

What are stablecoins?

• Stablecoins are digital tokens issued on blockchain platforms whose value is pegged to a stable reserve asset, such as a fiat currency or government bonds.
• The primary goal of stablecoins is to provide an alternative to the high volatility of popular cryptocurrencies like Bitcoin (BTC), which can make these digital assets less suitable for common transactions.

About USA Stablecoin

• In the US model, stablecoins are backed 1:1 by US Treasury Bills, ensuring price stability while leveraging the speed and transparency of blockchain technology.
• This means a bank in the US would be able to issue a digital version of the dollar, backed by government bonds, and it can be used for payments across the world. 

Hence it is a combination of government securities and the speed and transparency of blockchain technology.

How do stablecoins work?

• Stablecoins are stored and exchanged on decentralized networks (known as blockchains) that serve as ledgers of all transactions.
• No single intermediary is required for two parties to transact in crypto assets. 
• Instead, participants in a network receive small transaction fees for the computation expended to verify the validity of transactions

Usage

• Stablecoins are primarily used for trading crypto assets, transacting in goods and services, insulating against local currency instability, and sending payments across borders. Stripe allows stablecoin payments to US merchants with lower fees than cards.
• Used for hedging Currency Risks particularly popular in countries with volatile fiat currencies (Argentina, Nigeria, Turkey) to save in USD. According to 2024 Visa survey: 47% of users in Brazil, Turkey, Nigeria, India, and Indonesia use stablecoins for saving in dollars.
• Also used for Cross-Border Payments & Remittances.

India’s Position

In India, RBI has raised concerns about unregulated cryptocurrencies, particularly from a monetary policy and consumer protection standpoint. Hence it is using conventional tools like rate cuts.

However, stablecoins are different, as they are regulated, backed by government securities, and integrate blockchain with sovereign guarantees.

Where India lags?

• In India, there is no regulatory mechanism due to which legitimate fintech innovation remains stuck.
• Issues in digitising currency:

• • Lack of regulatory clarity pushes Indian blockchain developers and fintech startups to relocate abroad.
  • Risks of unregulated crypto turning into a “refined form of hawala”, demanding urgent regulation.
• Most Indian household savings remain in fixed deposits or gold, limiting formal financial market depth.

Steps needed

• Craft a balanced policy allowing stablecoins under RBI oversight, ensuring consumer protection, monetary stability, and legal clarity.
• Integrate blockchain-based products into the formal economy, supporting startups to build from India rather than relocating to Singapore or Dubai.
• Promote awareness on safe, regulated digital assets to deepen financial inclusion.

Conclusion

The stablecoin ecosystem isn’t just about finance — it’s about the future of fintech. It touches payments, digital wallets, eKYC, blockchain infrastructure, cybersecurity, tax compliance, and new forms of savings and investing. Hence, India should craft a framework that reflects Indian values — trust, transparency, and stability — while embracing the potential of fintech to create jobs, strengthen the rupee, and modernise our economy.

Mains Practice Question

“Stablecoins represent both an opportunity and a regulatory challenge for India’s fintech ecosystem.” Elaborate (250 words, 15 marks)
