The Securities and Exchange Board of India (SEBI) is considering a proposal to ease restrictions on short selling in most stocks.
SEBI’s January 2024 proposal to bar short-selling in stocks that are not in the futures and options segment had caused uncertainty.
What is Short Selling?
- Definition: Short selling is a strategy where an investor sells a stock first and buys it later, aiming to profit from a price drop.
- Opposite of Normal Trade: Unlike regular buying (buy low, sell high), short selling works on selling high and buying low.
- How It Works: You borrow the stock from a broker, sell it at the market price, and later buy it back at a lower price to return it.
- Example: If a stock is sold at ₹2,100 and later bought at ₹1,900, the profit is ₹200. If the price rises to ₹2,300 instead, the loss is ₹200.
Types of Short Selling:
- Short Selling in the Spot Market (Cash Segment):
- Shorting is allowed only for intraday trading (buying and selling financial instruments (like stocks) on the same day).
- You must square off the position (buy back the stock) before 3:30 p.m. on the same day.
- If not squared off, it leads to short delivery, where the exchange settles the trade through an auction.
- There may be heavy penalties if the position is not closed on time.
- Short Selling in the Futures Market:
- Here, you can hold your short position overnight or even roll it over to the next month.
- You must deposit margin money, which is generally higher.
- Futures shorting is riskier and is mostly used by experienced traders.
- This type allows more flexibility but involves greater financial commitment.
Risks Associated with Short Selling:
- Unlimited Losses: If the stock price rises sharply, losses are unlimited.
- Short Delivery Risk: Failing to buy back in the spot market can lead to penalties.
- Liquidity Risk: Hard-to-trade stocks may lead to delayed buybacks and losses.
- Margin Requirements: High margin costs in futures trading limit retail participation.
- Market Volatility: Sudden movements may cause unexpected losses.
- Not for Beginners: Due to complexity and high risk, short selling is unsuitable for new investors.

The Indian Council of Medical Research (ICMR) has developed the ICMR-SCD Stigma Scale for India (ISSSI) to help understand and reduce stigma faced by patients and caregivers from sickle cell disease (SCD).
What is Sickle Cell Disease (SCD)?
- Nature of Disease: SCD is a genetic disorder where red blood cells become sickle-shaped, reducing oxygen delivery in the body.
- Complications: These sickle cells can block blood vessels, break easily, and cause anemia, organ damage, and painful episodes.
- Cause: The disease is inherited, requiring one defective gene from each parent; one gene leads to sickle cell trait.
- Symptoms: Common symptoms include fatigue, body pain, swollen limbs, frequent infections, and organ damage.
- Treatment Options: There is no universal cure, but bone marrow transplants and gene therapy offer potential solutions; supportive care helps manage symptoms.
Note:
- Anaemia is a condition where the blood lacks enough healthy red blood cells (RBCs) or haemoglobin.
- All SCD patients have anaemia, but not all anaemia is due to Sickle Cell Disease.
|

About the ICMR-SCD Stigma Scale for India (ISSSI):
- Purpose: The ISSSI is India’s first tool designed to measure stigma faced by sickle cell disease (SCD) patients and their caregivers.
- Developing Authority: It was developed by ICMR to understand and address the social impact of SCD in India’s diverse communities.
- Global Context: This is the fourth stigma scale worldwide and the first validated for Indian conditions.
- Scientific Validation: The tool was validated in a study published in The Lancet (Regional Health – South-East Asia).
- Availability: The ISSSI is now approved for use in both clinical and research settings across India.
- Components: It includes two formats — ISSSI-Pt for patients and ISSSI-Cg for caregivers.
- Stigma Dimensions: It captures issues related to family expectations, reproductive concerns, social disclosure, illness burden, interpersonal challenges, and negative healthcare experiences.
- Data Sources: The scale was developed using inputs from 6 culturally diverse districts: Alluri Seetharama Raju, Anuppur, Chhoteudepur, Kandhamal, Mysuru, and Udalguri.
India’s Strategy: Anaemia Mukt Bharat (AMB)
- Launch Year: The AMB Mission was launched in 2018 to reduce anemia using a 6x6x6 strategy.

The Golaknath case (IC Golaknath v. State of Punjab, 1967) is one of the most important judgments in India’s constitutional history. It was the first time the Supreme Court said that Parliament cannot amend fundamental rights.
About the Golaknath v. State of Punjab (1967) Case:
- Case Name: IC Golaknath v. State of Punjab (1967) is a landmark case in Indian constitutional history.
- Background: The Golaknath family from Punjab challenged the Punjab Security of Land Tenures Act, 1953, which declared their land surplus under land ceiling laws.
- Claim of Violation: They argued the law violated their Fundamental Right to property, protected under Articles 19(1)(f) and 31.
- Ninth Schedule Issue: The Act was placed under the Ninth Schedule by the 17th Constitutional Amendment, making it immune to judicial review.
- Main Legal Question: Could Parliament amend Fundamental Rights under Article 368, or are such amendments invalid under Article 13(2)?
- Arguments: The petitioners claimed Fundamental Rights are sacrosanct, while the government asserted Parliament’s full power to amend the Constitution.
- Supreme Court Verdict: On February 27, 1967, in a 6:5 majority, the Court held that:
- Parliament cannot amend Fundamental Rights.
- Amendments are “law” and subject to Article 13(2).
- The ruling would apply only prospectively, not to past amendments.
- Overruled Judgments: The decision overturned earlier rulings in Sankari Prasad (1951) and Sajjan Singh (1964) that allowed unrestricted amendments.
Legacy of the Golaknath Case:
- Judicial Restraint on Parliament: This was the first case to restrict Parliament’s power to amend Fundamental Rights.
- Judiciary’s Role Strengthened: It reinforced the Supreme Court’s duty to protect civil liberties and limit legislative overreach.
- Prospective Overruling: Introduced the concept to ensure legal stability without undoing past amendments.
- Constitutional Values Upheld: Affirmed that the Constitution has core values that must be protected, especially Fundamental Rights.
Influence on Future Cases:
- Indira Gandhi Election Case (1975): Built upon the idea that democracy is a basic feature of the Constitution.
- Minerva Mills Case (1980): Reaffirmed limits on Parliament’s amending power and emphasised judicial review.
- Foundational Impact: Although later rulings allowed some flexibility, the Golaknath case laid the foundation for the Basic Structure Doctrine.
- Lasting Message: It ensured that Fundamental Rights remain untouchable, securing the heart of Indian democracy against future misuse.
[UPSC 2018] Consider the following statements:
1.The Parliament of India can place a particular law in the Ninth Schedule of the Constitution of India.

A new ETH Zurich study warns that under the Shared Socioeconomic Pathway (SSP) 5-8.5 scenario, warming could make cyclones more intense and hit unusual regions with greater damage.
What are Shared Socioeconomic Pathways (SSPs)?

- Definition: SSPs are 5 global scenarios that show how changes in society, economy, and technology might influence climate adaptation and mitigation.
- Purpose: They complement Representative Concentration Pathways (RCPs) by adding socioeconomic context to climate models.
- Development: Created in the late 2000s, published in 2016, and used in the IPCC 6th Assessment Report and CMIP6 models.
- Function: SSPs assume no new climate policies, helping scientists explore how global trends affect emissions and climate action.
- The Five Pathways:
-
- SSP1: Sustainable and equitable world
- SSP2: Continuation of current trends
- SSP3: Regional rivalry with high population growth
- SSP4: Unequal world with high disparities
- SSP5: Fossil-fuel-based rapid economic growth
- Usage: SSPs are used with RCPs to explore how different futures could affect the 1.5°C or 2°C warming targets.
- Significance: They help policymakers assess how societal choices impact climate risks, emissions, and the feasibility of global goals.
|
About SSP5-8.5 and Cyclone Risks:
- Scenario Summary: SSP5 shows rapid economic growth fuelled by fossil fuels.
- Radiative Forcing: SSP5-8.5 implies 8.5 W/m² of energy, compared to about 2.7 W/m² today.
- Climate Target Gap: To limit warming below 2°C, forcing must stay around 2.6 W/m².
- Cyclone Projections: Using the CLIMADA (climate adaptation) AI model, scientists studied past cyclone patterns and projected risks from 2015–2050.
- Ecoregion Types:
-
- Resilient: Often affected, but recover quickly
- Dependent: Moderately impacted and adaptive
- Vulnerable: Rarely hit but slow to recover
- Findings:
- Time between severe cyclones in resilient areas may drop from 19 to 12 years.
- East Asia, Central America, and the Caribbean will face stronger, more frequent cyclones.
- Madagascar, Oceania, and the Philippines will face unprecedented cyclone activity.
Impact on Mangroves and Coastal Ecosystems:
- Mangrove Risk: By 2100, up to 56% of global mangroves could be at high to severe risk.
- Most Affected Region: Southeast Asia, with 52–78% of mangroves at risk.
- Other Scenario Impact (SSP3-7.0): Even under less severe warming, 97–98% of protective mangroves in Southeast Asia could still face critical threats.
- Environmental Concern: These losses would severely weaken coastal protection, biodiversity, and carbon storage.
[UPSC 2020] Consider the following statements:
1. Jet streams occur in the Northern Hemisphere only. 2. Only some cyclones develop an eye. 3. The temperature inside the eye of a cyclone is nearly 10°C lesser than that of the surroundings.

Scientists have discovered that a massive solar storm hit Earth around 12,350 BC, making it the most powerful solar event ever detected.
What are Solar Particle Storms?
- About: A solar storm is a disturbance caused by solar flares or coronal mass ejections that release charged particles into space.
- Solar Particle Storm: It is a type of solar storm where high-energy particles travel toward Earth, producing cosmogenic isotopes like radiocarbon.
- Detection: These isotope spikes are recorded in tree rings and are known as Miyake events, which act as cosmic timestamps.
- Impact: Though rare, solar particle storms can severely affect satellites, communication systems, and power grids.
- Historical Events: Major solar particle storms were identified in AD 994, 663 BC, 5259 BC, and 7176 BC.
- Carrington Event (1859): This was a major solar storm, but not a particle storm—it resulted from a different solar mechanism.
How was the ancient storm detected?
- Methodology: A solar storm from 12,350 BC was discovered using tree-ring data from the French Alps.
- Event Strength: This storm was over 500 times stronger than the 2005 solar storm, the largest in the satellite era.
- What are its implications?
- Significance: This is the first known extreme solar event before the Holocene, predating the last 12,000 years of stable climate.
- Modern Relevance: The discovery highlights the risks of future extreme solar activity on Satellite infrastructure and Space Application.
- Significance: Miyake events improve the precision of archaeological dating, helping better understand ancient human history.
[UPSC 2022] If a major solar storm (solar flare) reaches the Earth, which of the following are the possible effects on the Earth?
1. GPS and navigation systems could fail.

Jayant Narlikar, renowned Indian astrophysicist and Padma Vibhushan awardee, who co-developed the Hoyle–Narlikar Theory to refine Einstein’s Theory of Relativity, passed away in Pune at the age of 87.
About Jayant Narlikar and His Contributions:

- Early Life: Born in 1938 in Kolhapur, Maharashtra, and pursued a PhD at Cambridge University under Fred Hoyle.
- Scientific Influence: Hoyle had earlier developed the steady-state theory with Bondi and Gold and coined the term “Big Bang” sarcastically in 1948.
- Narlikar’s Belief: He argued that the universe always looks the same, as new matter fills the gaps created by expansion.
- Critique of Big Bang: He believed the Big Bang theory includes unproven assumptions, especially about the sudden origin of all matter and energy.
- Enduring Work: Despite steady-state theory’s decline, Narlikar’s contributions remain respected for their scientific depth and originality.
|
What Is the Hoyle–Narlikar Theory?
Fred Hoyle and Jayant Narlikar developed a theory to answer one of the most basic questions: Why do things have mass, and how are they connected to the rest of the universe?
- Based on Mach’s Principle: They believed your mass isn’t just something you have on your own. Instead, it depends on your connection to everything else in the universe. That means even faraway stars and galaxies play a role in what you weigh.
- Inertia Explained: In simple terms, when you feel resistance while trying to move (inertia), it’s because of the gravitational pull of all the matter in the universe acting on you at once.
- Mass is Relative: Earth, the Sun, or even you don’t have a fixed mass. That mass is influenced by everything else that exists out there, no matter how far away it is.
- C-field and Steady-State Model
- New Idea – C-Field: They introduced the “creation field”, which creates new matter in space.
- Universe Without a Start: Their steady-state theory says the universe has no beginning or end, is always expanding, and keeps its density constant.
- Against the Big Bang: They believed the Big Bang couldn’t explain everything we see today.
- Hydrogen Creation: They said hydrogen atoms form in space to fill in the gaps as the universe grows.
-
- CMB Discovery (1965): Scientists found cosmic microwave background radiation, strong proof of the Big Bang.
- Other Evidence: Later discoveries like young, chaotic galaxies and studies by Hawking and Penrose supported the Big Bang.
- Current View: The Big Bang theory became more accepted, but Hoyle and Narlikar’s ideas are still respected for their scientific value.
[UPSC 2018] Consider the following phenomena:
1. Light is affected by gravity.
2. The Universe is constantly expanding.
3. Matter warps its surrounding space-time.
