Prelims level: Pulsars, Neutron Stars, Glitches
Mains level: NA

Introduction
- In 1967 a group of astronomers at the University of Cambridge stumbled upon a celestial mystery that would unravel the secrets of neutron stars.
- Jocelyn Bell Burnell and Antony Hewish observed periodic signals emanating from the depths of space, eventually discovering the first pulsar, PSR B1919+21.
Pulsars and Neutron Stars
- The Birth of a Pulsar: PSR B1919+21 initially puzzled scientists, who considered various explanations, even the possibility of signals from extraterrestrial life.
- Neutron Stars: Neutron stars are born from the remnants of massive stars that didn’t become black holes. They are incredibly dense and primarily made up of neutrons.
Behind the Radiation: Lighthouse Effect
- Radiation Beams: Pulsars emit focused beams of radio waves, similar to a lighthouse’s rotating light.
- Rotation Slowdown: Neutron stars gradually slow down their rotation, and this process generates the pulsar’s radio signals.
The Mystery of Glitches
- Sudden Speed-Ups: In 1969, scientists noticed unexpected and brief increases in the rotation speed of pulsars, known as “glitches.”
- Unsolved Riddle: Even after more than four decades of study, the cause of these glitches remains a mystery, although scientists have developed some ideas.
- Common Occurrence: Around 700 glitches have been observed in more than 3,000 pulsars.
Clues in the Rotation
- Post-Glitch Behavior: During a glitch, the pulsar’s rotation rate temporarily increases before gradually returning to its previous speed.
- Sign of Internal Changes: The slow post-glitch recovery suggests that the neutrons inside the star behave like a special kind of fluid, called a superfluid, with very low friction.
- Superfluids and Vortices: Superfluids, like the one inside a neutron star, exhibit vortex behavior, which is like tiny whirlpools.
The Glitch Mechanism
- Neutron Star Structure: Neutron stars have a solid outer layer with superfluid patches and a core primarily made of superfluid.
- Vortex Pinning: Vortices within the superfluid like to stick to the crust or solid parts of the star, which keeps the superfluid rotating.
- How Glitches Happen: As the star loses energy over time, the crust slows down, but the pinned vortices stay at their original speed. When the difference becomes too great, the vortices are released, transferring energy from the superfluid to the crust, causing a glitch in the pulsar’s rotation.

From UPSC perspective, the following things are important :
Prelims level: Gini Coefficient
Mains level: Not Much

Introduction
- A recent report by the State Bank of India (SBI) has illuminated a significant decline in income inequality in India over the past decade.
- This report, which analyzes taxpayer data, indicates a substantial reduction in the Gini coefficient, a widely accepted measure of income inequality.
What is the Gini Coefficient?
- The Gini Coefficient, often referred to as the Gini Index or Gini Ratio, is a measure of income or wealth inequality within a specific population, region, or country.
- It assigns a numerical value between 0 and 1.
- 0 represents perfect income or wealth equality (everyone has the same income or wealth), and 1 signifies perfect inequality (one person or household has all the income or wealth, and everyone else has none).
- To calculate the Gini Coefficient, income or wealth data is typically arranged in ascending order, from the poorest to the richest individuals or households.
- A Lorenz curve is plotted, which is a graphical representation of the actual income or wealth distribution. It compares the cumulative income or wealth of the population to the cumulative share of the population.
- The Gini Coefficient is calculated by measuring the area between the Lorenz curve and the line of perfect equality. This area is then divided by the total area under the line of perfect equality.
Gini Coefficient and Income Inequality
- Gini Coefficient: The Gini coefficient measures income inequality, ranging from 0 (perfect equality) to 1 (perfect inequality).
- Reported Decline: The Gini coefficient has dropped from 0.472 in 2014-15 to 0.402 in 2022-23, marking a nearly 15% reduction in income inequality.
Examining Income Inequality across Employment Types
- Taxpayer Data Limitation: The SBI report focuses on taxpayer data, potentially excluding a significant portion of income earners.
- Significant Majority below Tax Threshold: Approximately 80% of income earners earn less than ₹2.5 lakh per annum, the minimum taxable amount.
A Closer Look at the Gini Coefficient
- Preliminary Analysis: Data from the 2017-18 and 2022-23 Periodic Labour Force Surveys (PLFS) is analyzed to evaluate changes in income inequality among various employment categories.
- Gini Coefficient Trends: While the Gini coefficient decreases slightly from 0.4297 to 0.4197, the changes are minimal.
- Disaggregated Gini: The Gini coefficient falls for regular wage and casual wage workers but rises for the self-employed, though the shifts are modest.
Uncovering Income Polarization
- Beyond the Gini Coefficient: Income polarization becomes evident when examining the top 10% compared to the bottom 30% of income earners.
- Divergence in Income Growth: The top deciles witnesses’ faster income growth (around 7.23%) compared to the bottom 20% and even the third decile. In contrast, the bottom decile experiences the slowest growth (approximately 1.67%).
- The 90/10 Ratio: The ratio of incomes between the 90th percentile (top 10%) and the 10th percentile (bottom 10%) rises from 6.7 in 2017-18 to 6.9 in 2022-23, indicating increased income disparity.
- Variation among Employment Types: The 90/10 ratio falls for wage earners but significantly increases for the self-employed, particularly among top earners.
Analyzing the Changes
- Preliminary Assessment: While this analysis offers initial insights, further research is needed to comprehensively understand these trends.
- Impact of Women’s Participation: The rise in women’s labor force participation, primarily in low-paid self-employed roles, may explain the increased polarization among income earners.
- Tax Data Limitations: Taxpayer data might not capture the pace of inequality reduction among the broader population.
- Complex Inequality Dynamics: Reduction in the Gini coefficient conceals income divergence, and future growth may either mitigate or exacerbate this disparity.
Conclusion
- The SBI report’s revelation of declining income inequality in India is a positive development.
- However, a deeper examination of income distribution across employment types and deciles unveils a more complex picture.
- Income polarization, particularly among the self-employed, challenges the overarching narrative of reduced inequality.

Prelims level: Mosquitofish
Mains level: Read the attached story

Introduction
- In recent months, several regions in India, including Andhra Pradesh, Odisha, and Punjab, have resorted to releasing mosquitofish into local water bodies as a means to combat mosquito-borne diseases.
- While this approach aims to address a pressing public health concern, it brings to light ecological challenges associated with the introduction of mosquitofish.
Understanding Mosquitofish
- Biological Control of Mosquitoes: Mosquitofish, particularly Gambusia affinis and Gambusia holbrooki, were introduced in freshwater ecosystems in the 1960s as an eco-friendly alternative to chemical pesticides for mosquito control.
- Widespread Distribution: Originally native to the U.S., these fish have become global inhabitants due to their adaptability and tolerance to environmental fluctuations.
- Unintended Consequences: Despite good intentions, the proliferation of mosquitofish has led to detrimental ecological and environmental effects.
Historical Use in India
- Early Introduction: Gambusia was first introduced in India in 1928 during British rule as a measure to combat malaria.
- Government and Non-Governmental Involvement: Various governmental organizations, such as the Indian Council of Medical Research (ICMR) and the National Institute of Malaria Research (NIMR), as well as local municipal corporations and health departments, were entrusted with introducing mosquitofish.
- Widespread Distribution: Gambusia species are now established in multiple habitats across India.
Ecological Impact
- Invasive Alien Species: Mosquitofish are among the hundred most detrimental invasive alien species worldwide, leading to the displacement and extinction of native fauna.
- Threat to Biodiversity: They exhibit voracious feeding habits and aggressive behavior, posing a threat to native fish, amphibians, and freshwater communities.
- Global Examples: Studies in Australia, New Zealand, and India have shown the harmful consequences of Gambusia presence, including the decline of endemic species and predation on native fish and frogs.
Sustainable Alternatives
- WHO Recommendations: The World Health Organization stopped recommending Gambusia as a mosquito control agent in 1982.
- Government Recognition: In 2018, the National Biodiversity Authority of the Government of India designated G. affinis and G. holbrooki as invasive alien species.
- Local Solutions: Collaborative efforts between mosquito biologists, entomologists, invasion ecologists, and fish taxonomists can identify native fish species capable of mosquito control.
- River Basin Approach: Authorities can compile lists of native fish species in each river basin that are effective in controlling mosquito larvae, offering an eco-friendly alternative to invasive species.
Conclusion
- The introduction of mosquitofish in India, once intended to combat mosquito-borne diseases, has led to ecological challenges and the disruption of native ecosystems.
- To mitigate the adverse effects and protect indigenous aquatic biodiversity, it is essential to discontinue the use of Gambusia and instead explore sustainable alternatives rooted in local solutions.
- By adopting a river basin approach and collaborating across disciplines, India can strike a balance between mosquito control and environmental preservation.

About Ingenuity
- Inaugural Flight: Ingenuity landed on Mars on February 18, 2021, alongside the Perseverance Rover. On April 19 of the same year, it achieved the first powered extraterrestrial flight in human history.
- Launch and Deployment: NASA launched a spacecraft on July 30, 2020, carrying the Perseverance rover with Ingenuity attached. The helicopter was deployed on the Martian surface on April 4, 2021, after reaching a suitable “airfield” location.
- Experimental Purpose: Ingenuity’s primary mission was experimental, aiming to test powered, controlled flight on another celestial body.
- Historic Flight: During its maiden flight, Ingenuity hovered, covered the same spot, and remained airborne for an impressive 39.1 seconds, establishing a historic milestone.
Challenges and Impressive Records
- Vast Distances: Despite the relatively short flight duration, Mars’ distance of over 225 million kilometres from Earth results in signal delays of 5 to 20 minutes.
- Harsh Martian Conditions: Ingenuity must endure Mars’ challenging conditions, including low atmospheric density, “continent-sized” dust storms, and various hazards.
Significance of Mars Flight
- Historical Milestone: On April 19, 2021, Ingenuity’s inaugural flight marked two significant achievements. Firstly, it was the first aircraft to fly on another planet. Secondly, it operated in Mars’ thin atmosphere, unsuitable for conventional flight.
- Challenges of Martian Flight: Ingenuity’s flight on Mars was challenging due to the planet’s lower gravity, one-third that of Earth’s, and its extremely thin atmosphere with just 1% of Earth’s surface pressure.
- Autonomous Operation: Ingenuity is an autonomous aircraft, piloted by onboard guidance, navigation, and control systems, running algorithms developed by NASA’s Jet Propulsion Laboratory. Perseverance serves as a crucial link between the chopper and Earth.
Evolving Mission Role
- Scouting and Exploration: Initially designed for a limited number of flights, Ingenuity’s role evolved as scientists began to use it for scouting. It aided Perseverance in exploring Martian terrain efficiently, avoiding unexceptional rocks and enhancing mission productivity.
- Impressive Flight Record: Before the recent communication lapse, Ingenuity completed 72 flights, accumulating more than 128 minutes of flight time and covering a total distance of 17.7 kilometers, as recorded in the mission’s flight log.

Prelims level: Migration for Employment Convention
Mains level: Read the attached story
Introduction
- The governments of Uttar Pradesh and Haryana, in collaboration with the National Skill Development Corporation (NSDC), have initiated the recruitment of around 10,000 workers for employment in Israel, primarily for construction roles.
- These workers are being recruited to address employment challenges and offer an opportunity for overseas employment.
Labour Laws: International Practices
- ILO Conventions: International labor standards are governed by conventions of the International Labour Organisation (ILO).
- India’s Non-Ratification: India has not ratified these conventions, while Israel ratified the Migration for Employment Convention (Revised), 1949, in 1953.
- Action against Misleading Propaganda: The 1949 convention calls for action against misleading propaganda related to emigration and immigration.
Emigration Rules
- Registration Requirement: Workers going to conflict zones or regions lacking sufficient labor protections are required to register on the Ministry of External Affairs’ ‘e-migrate’ portal.
- Exclusion of Israel: However, Israel is not on the list of countries covered by this requirement, despite ongoing violence in certain areas.
Opposition and Legal Concerns
- Conflict Zone Concerns: Central trade unions argue that sending workers to a region of conflict goes against the principles of bringing back citizens from such zones.
- Political Motivation: They assert that the government’s move is politically motivated and aimed at pleasing Israel.
- Service Charges: Trade unions highlight that the Emigration Act prohibits the collection of service charges exceeding ₹30,000 from workers.
- High Recruitment Costs: In the case of recruitment for Israel, workers are required to pay a significant fee to the NSDC, as well as cover other expenses, adding up to nearly ₹1 lakh.

Introduction
- The upcoming inauguration of the Ram temple in Ayodhya designed by Chandrakant Sompura and his son Ashish in the Nagara style of temple architecture has piqued interest in the rich architectural heritage of India.

Emergence of Nagara Architecture
- Historical Context: Nagara architecture originated in northern India during the late Gupta period, around the 5th century CE.
- Contrasting Styles: It stands in contrast to the Dravida style prevalent in southern India, both evolving around the same period.
“Languages” of Architecture
- Debating Terminology: While commonly referred to as “styles,” Nagara and Dravida are more accurately described as “languages” of temple architecture.
- Architectural Vocabulary: Each language provides a unique vocabulary and a set of rules for assembling architectural elements.
Distinctive Features of Nagara Temples
- Raised Plinth: Nagara temples are built on elevated plinths, with the sanctum sanctorum (garbha griha) as the most sacred part.
- Towering Shikhara: The shikhara, or tower, is the hallmark of Nagara temples and symbolizes the natural and cosmological order in Hindu tradition.
- Circumambulatory Passage: A path encircles the garbha griha, allowing devotees to circumambulate the inner sanctum.
- Mandapas and Ornamentation: Nagara temples often feature multiple halls (mandapas) and intricate murals and reliefs on their walls.
Modes of Nagara Architecture
- Five Modes: Nagara architecture has evolved over time, leading to five distinctive modes: Valabhi, Phamsana, Latina, Shekhari, and Bhumija.
- Early Nagara Style: Valabhi and Phamsana are associated with the early Nagara style, resembling barrel-roofed structures and multi-eave towers.
- Dominance of Latina: Latina, a single curved tower with equal sides, reigned supreme for three centuries starting in the 7th century.
- Later Developments: Shekhari introduced attached sub-spires, while Bhumija featured miniature spires in horizontal and vertical rows, creating a grid-like effect.
Diversity within Modes
- Simplified Classifications: These modes are scholastic classifications, and actual temple architects didn’t consciously adhere to a particular mode.
- Variation Abounds: Temples often exhibit variations within these modes, with multiple shikharas atop a single structure.
Contrasting Dravida Architecture
- Vimana vs. Gopuram: In Dravida style temples, the vimana (tower) is smaller than the prominent gopurams (gatehouses).
- Boundary Walls: Dravida temples often feature boundary walls, a unique feature not commonly seen in Nagara style temple complexes.
- Ayodhya’s Unique Blend: Ayodhya’s Ram temple combines elements of both styles, featuring a boundary wall but not elaborate gopurams.
