From UPSC perspective, the following things are important :
Prelims level: N332-GT5, eOD-GT8, HIV-AIDS
Why in the News?
Researchers at the Duke Human Vaccine Institute have successfully induced broadly neutralising antibodies (bNAbs) against HIV (human immunodeficiency virus) through vaccination for the first time.
About HIV/AIDS:
Emergence: The first cases of AIDS (Acquired Immunodeficiency Syndrome) were reported in the early 1980s, primarily among gay men in the United States.
Discovery of HIV: In 1983-1984, scientists identified HIV (Human Immunodeficiency Virus) as the cause of AIDS.
Global Spread: HIV/AIDS quickly became a global pandemic, affecting millions of people worldwide.
Causes:
HIV is transmitted through contact with certain body fluids of an infected person, including blood, semen, vaginal fluids, and breast milk.
Common modes of HIV transmission include unprotected sexual intercourse, sharing needles or syringes, and from mother to child during pregnancy, childbirth, or breastfeeding.
Symptoms:
Acute HIV Infection: Many people experience flu-like symptoms, such as fever, headache, fatigue, and swollen lymph nodes, within 2-4 weeks after infection.
Asymptomatic Stage: After the initial symptoms subside, HIV often enters a latent stage where individuals may not experience any symptoms for years.
Progression to AIDS: Without treatment, HIV gradually weakens the immune system, leading to the development of opportunistic infections and cancers. This advanced stage is known as AIDS and is characterized by severe immune deficiency.
Vaccines Development:
Challenges: Developing an HIV vaccine has been challenging due to the virus’s ability to mutate rapidly and evade the immune system.
Vaccine Candidates: Numerous vaccine candidates have been tested over the years, but none have yet been successful in providing robust protection against HIV infection.
Hope for the Future: Despite setbacks, advances in vaccine development, such as the identification of promising candidates like N332-GT5 and eOD-GT8, offer hope for eventually achieving an effective HIV vaccine.
How B cells and mRNA play distinct roles in the context of HIV infection?
1. B cells (B lymphocytes):
B cells are a type of white blood cell crucial for the immune response.
In HIV infection, B cells participate in the adaptive immune response by producing antibodies specific to HIV antigens.
These antibodies can neutralize HIV particles, tag infected cells for destruction by other immune cells, and contribute to the immune memory against HIV.
2. mRNA (messenger RNA):
mRNA is a molecule that carries genetic information from DNA to the ribosomes, where proteins are synthesized.
In the context of HIV, mRNA is involved in the replication process of the virus.
HIV uses its RNA genome to produce viral mRNA, which directs the synthesis of viral proteins necessary for the assembly of new virus particles.
Understanding HIV mRNA is crucial for developing antiviral therapies that target viral replication, such as mRNA-based vaccines or mRNA inhibitors.
N332-GT5 and eOD-GT8: The New Vaccines in Making
N332-GT5: This vaccine candidate targets a specific region on the surface of the HIV virus known as the N332 glycan site. By engaging B-cells that have the potential to produce bNAbs against this site, N332-GT5 aims to stimulate the immune system to generate a protective response against a wide range of HIV strains.
eOD-GT8: Similarly, eOD-GT8 is designed to target another region on the HIV virus, known as the eOD protein. By leveraging nanoparticles as carriers, eOD-GT8 aims to enhance the immune system’s ability to recognize and neutralize HIV, ultimately leading to the production of bNAbs.
What are Broadly Neutralizing Antibodies (bNAbs)?
In the 1990s, scientists discovered that some HIV-infected individuals produced bNAbs, which neutralize many viral strains.
bNAbs target viral protein areas crucial for infectivity, making them less likely to change.
Despite their effectiveness, bNAbs take years to develop, by which time HIV has often evolved to escape them.
Developing bNAb-Based Vaccines
The goal is to make the immune system produce bNAbs quickly in response to a vaccine.
Germline targeting involves three steps:
Identify and engage B-cells capable of producing bNAbs.
Use a booster to guide these cells to produce stronger bNAbs.
Refine bNAbs to neutralize a wide range of HIV strains.

Low Population Density or High Tribal Population: States with a considerable proportion of tribal population or low population density.
Economic and Social Backwardness: States that are economically and socially disadvantaged.
Strategic Location: States that share international borders or have strategic significance.
Why has Bihar’s demand been a long-standing issue?
Economic Backwardness: Bihar has one of the lowest per capita incomes in India and lags behind in several human development indicators.
Fiscal Challenges: The bifurcation of the state leading to the formation of Jharkhand, frequent natural disasters, and insufficient water resources for irrigation have adversely affected Bihar’s fiscal situation.
Political Reiteration: Successive Bihar governments have continuously demanded special status to help the state’s development.
What are the political implications of granting ‘Special Status’ to Bihar?
Increased Bargaining Power: Granting special status could enhance Bihar’s political leverage with the central government, especially in coalition politics.
Precedent for Other States: Granting special status to Bihar could lead to similar demands from other states, potentially creating financial burdens for the Centre.
Electoral Promises and Alliances: Political parties may use the promise of special status as an electoral tool to gain or maintain power, as seen with the Congress party’s manifesto promise in 2024.
Centre-State Relations: The decision could impact the dynamics of center-state financial relations and influence the federal structure of revenue distribution in India.
Conclusion: The Central government should establish a transparent and well-defined framework for granting special category status, taking into account various economic, geographic, and social parameters. This framework should be periodically reviewed to ensure it remains relevant and fair to all states.

Prelims level: Quantum Theory and related Researches, National Quantum Mission (NQM)
Why in the News?
The United Nations has designated 2025 as the ‘International Year of Quantum Science and Technology’ to increase public awareness about the significance of quantum science and its applications.
This initiative, led by Mexico and supported by nearly 60 countries, aims to promote activities at all levels to highlight the importance of quantum science and technology worldwide.
International Year of Quantum S&T
Growing Relevance: Quantum science and technologies, especially quantum computing, have gained prominence in public discourse due to their potential transformative impact on various fields.
Anniversary of Heisenberg’s Work: The proclamation coincides with the upcoming centenary of Werner Heisenberg’s groundbreaking paper on quantum mechanics, published in 1925.
Support from International Bodies: The proclamation has received endorsements from various international organisations, including the International Union of Pure and Applied Physics and the International Union of Pure and Applied Chemistry.
What does one mean by Quantum?
“Quantum” refers to the smallest discrete unit of any physical quantity involved in an interaction according to quantum theory.
In classical physics, many properties, such as energy and momentum, are thought to be continuous and infinitely divisible.
However, in quantum mechanics, certain properties, like energy levels and the behaviour of particles, are quantised, meaning they can only exist in specific discrete amounts or levels.
What is Quantum Theory?
Quantum theory is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles.
Quantum mechanics differs from classical physics in that energy, momentum, and angular momentum.
Development in Quantum Theory So Far
Planck’s assumption: In 1900, Planck made the assumption that energy was made of individual units or quanta.
Albert Einstein’s theory: In 1905, Albert Einstein theorized that not just the energy, but the radiation itself was quantized in the same manner.
Louis de Broglie theory: In 1924, Louis de Broglie proposed that there is no fundamental difference in the makeup and behaviour of energy and matter; on the atomic and subatomic level either may behave as if made of either particles or waves. This theory became known as the principle of wave-particle duality: elementary particles of both energy and matter behave, depending on the conditions, like either particles or waves (wave-particle duality).
Heisenberg proposed: In 1927, Werner Heisenberg proposed that precise, simultaneous measurement of two complementary values – such as the position and momentum of a subatomic particle – is impossible. Contrary to the principles of classical physics, their simultaneous measurement is inescapably flawed; the more precisely one value is measured, the more flawed will be the measurement of the other value. This theory became known as the uncertainty principle, which prompted Albert Einstein’s famous comment, “God does not play dice.”
What is Entanglement?
Entanglement was another of several weird properties exhibited by these tiny particles.
Two particles, having ‘interacted’ with each other at some stage, were found to have got ‘entangled’ in a way that the behaviour of one produced an instantaneous reaction in the other even if the two were no longer connected in any way and were separated by very large distances.
The entanglement property opened up new technological possibilities first time that it was possible to ‘teleport’ the quantum states of a particle to another location without the particle moving anywhere and without a medium.
What is Superposition?
It’s a phenomenon where, a particle exists simultaneously at multiple locations, known as superposition.
The chance of finding the particle at any given place was dictated by probabilistic calculations, and once it was found, or observed, at one location, it ceased to exist at all other places.
What is Quantum Computing?
Quantum computing is a new and super powerful way of doing computer stuff.
Instead of using regular computer bits that are either 0 or 1, quantum computers use special bits called qubits that can be both 0 and 1 at the same time, thanks to a thing called “quantum superposition.”
This allows them to do lots of calculations all at once, making them really fast at solving certain types of problems.

Prelims level: Optical Atomic Clock and Classical Atomic Clock; Difference between them.
Why in the News?
Atomic clocks power GPS systems, guiding us in navigation, emergencies, and military operations.
Scientists are developing optical atomic clocks to enhance timekeeping accuracy for Navies.
What are Atomic Clocks?
Atomic clocks are accurate timekeeping devices that use the vibrations of atoms as a precise measure of time.
They rely on the natural oscillations of atoms, usually Caesium or Rubidium atoms, which are extremely stable and predictable.
This stability allows atomic clocks to keep time with extraordinary accuracy, often losing or gaining less than a second over millions of years.
However they are big, need a lot of power, and are expensive, so they’re mostly used in big research places.
Working Principle:
Use of Stable Atoms: Atomic clocks use stable atoms like Cs-133 to keep time really accurate.
Atom Energy Levels: Atoms have energy levels like steps on a ladder, and they move between these levels when they’re excited.
Creating Resonance: Cesium atomic clocks make caesium atoms vibrate by using microwave radiation at a certain frequency.
Defining Time: One second is how long it takes for caesium atoms to vibrate a certain number of times, which sets the standard for time.
Accuracy Control: Atomic clocks keep themselves accurate by constantly adjusting to make sure they’re vibrating at the right rate.
Portable Optical Atomic Clocks for Maritime Use
New portable optical atomic clocks for ships are more accurate and durable, making them suitable for use at sea.
These clocks are the best at sea, which is a big deal for keeping time on ships.
How Optical Atomic Clocks Are Different?
Use of Laser: Optical atomic clocks are even more accurate because they use lasers instead of microwaves.
Operating Frequency: They work at higher frequencies, which means they can measure smaller time intervals more precisely.
Narrow Linewidths: Optical atomic clocks are really stable because they have a narrow range of frequencies, which helps them stay accurate.
Testing and Applications of Portable Optical Atomic Clocks
Initial Testing: Scientists tested the new clocks and found they were really stable and accurate, which is a big deal for keeping time.
Comparative Performance: These new clocks worked better than old ones, showing they could change how we keep time.
Sea Trials: Tests at sea showed the clocks worked well even on a moving ship, proving they could be used for navigation and other important tasks.
Do you know?
Three rubidium atomic clocks and six hydrogen maser clocks onboard the Indian Regional Navigation Satellite System (IRNSS) had failed.
The failed satellite, IRNSS-1A, is still being used for messaging activities, and the data from other operational satellites will be used to maintain the system’s functionality.

From UPSC perspective, the following things are important :
Prelims level: Constitutional mandate of the Speaker
Mains level: Powers of the Speaker
Why in the News?
The pivotal role of the Speaker in parliamentary democracy is underscored as both the TDP and JD(U), crucial allies within the NDA, compete for the position, highlighting its significance.
Constitutional Mandate:
Speaker and Deputy Speaker are elected as per Article 93 of the Constitution, with the Speaker chosen by a simple majority.
The speaker’s term ends with the House dissolution and no-confidence motion can be moved against the Speaker.
No specific qualifications for the Speaker, who is distinct from other members.
Powers of the Speaker
Conducting the House: The Speaker decides House conduct and government business, ensuring adherence to rules, crucial for opposition participation. There are Rules and Procedure for the functioning of the House, but the Speaker has vast powers in ensuring these Rules are followed, and in choosing procedures.
Questions & Records: The Speaker holds authority over determining the validity of queries raised by members and overseeing the publication of House proceedings. The Speaker possesses the power to remove, wholly or partially, statements deemed unparliamentary.
Voice Votes, Division: The speaker can push bills through by voice vote or division, crucial for the legislative process.
As per the Rules of Procedure and Conduct of Business in Lok Sabha, if the Speaker thinks that is “unnecessarily claimed”, simply ask the members who are for ‘Aye’ and those for ‘No’ respectively to rise in their places and decide.
No-Confidence Motion: A pivotal moment where the Speaker’s neutrality significantly affects the Opposition is during the presentation of a motion of no-confidence against the government.
In 2018, when notices for a no-confidence motion were submitted by the YSRCP and TDP, Speaker Sumitra Mahajan postponed the House multiple times before acknowledging the motion and conducting the vote.
Casting Vote: As per Article 100 of the Constitution, pertaining to voting in the Houses, the Chairperson of the Rajya Sabha or the Speaker of the Lok Sabha, or any individual acting in such a capacity, “shall refrain from voting initially but must cast a deciding vote in the event of a tie.”
His Removal:
Motion: A member of the Lok Sabha gives a written notice for the removal of the Speaker, citing specific grounds such as misconduct or inability to perform duties.
Support: The motion needs support from at least 50 members to be admitted for discussion in the House.
Resolution: Once admitted, the House discusses the motion. If the majority of members present and voting support the motion, a resolution for the Speaker’s removal is passed.
Note: During the process of removal of the Lok Sabha Speaker in India, the Speaker typically remains present and presides over the proceedings until the resolution for their removal is passed. The Speaker maintains their role in overseeing the House’s functioning unless and until the majority of members vote in favor of the motion to remove them. Once the resolution is passed and approved by the President, the Speaker ceases to hold office and their duties are formally relinquished.
Disqualification of Members
Power of the Speaker: The Speaker of the House holds the authority to disqualify legislators who defect from their party, as per the provisions of the Tenth Schedule.
Introduction of the Anti-Defection Law: The Tenth Schedule, also known as the anti-defection law, was incorporated into the Constitution in 1985 through the Fifty-Second (Amendment) Act.
Judicial Review: The Supreme Court, in the landmark case of Kihoto Hollohan versus Zachillhu in 1992, upheld the power vested in the Speaker to decide on defection cases. It ruled that only the final order of the Speaker is subject to judicial review.
Impact on Government Stability: Defections can change the numerical strength of political parties in the House, potentially destabilizing governments if members defect in significant numbers. Timely action by the Speaker in disqualifying defective members is crucial to maintaining the integrity of the Tenth Schedule and ensuring that governments retain their majority.
Supreme Court Directives: The Supreme Court has issued directives emphasizing the need for Speakers to expedite disqualification proceedings. For instance, in 2020, it ruled that Speakers must decide on disqualification pleas within three months, except in exceptional circumstances.
Impact on Government Formation: Delays in deciding disqualification petitions can have significant political ramifications, as seen in cases where governments have collapsed due to prolonged delays in addressing defection issues.
Case Example: In 2023, the Supreme Court directed the Maharashtra Assembly Speaker to expedite disqualification proceedings against members of factions within the Shiv Sena party. Prolonged delays in these proceedings contributed to the collapse of the government led by Uddhav Thackeray.
Conclusion: The Speaker holds significant powers in conducting the House, ensuring adherence to rules, deciding on crucial matters like no-confidence motions, and maintaining political stability through the judicious application of these powers.

Cabinet committees in India are groups of ministers formed by the Prime Minister to handle specific tasks or issues more efficiently.
The PM sets up these committees with selected members of the Cabinet and assigns specific functions to these committees.
The PM may changethe number of committees, and modify the functions assigned to them.
Usually, only Cabinet ministers are members of these committees. However, non-Cabinet ministers are not unheard of to be members or special invitees to committees.
If the PM himself is a member of any such committee, he acts as the head of that committee.
Evolution of Cabinet Committees in India’s Governance
Cabinet committees operate under the Government of India Transaction of Business Rules, 1961.
These committees are categorized as Standing (Permanent) or Ad-Hoc (Temporary).
They are established based on Article 77(3) of the Constitution, allowing the President to make rules for efficient transaction of government business and allocation among ministers.
Membership varies from three to eight, predominantly comprising Cabinet ministers, with the Prime Minister often presiding.
The number, terminology, and composition may change over time.
Note: All Cabinet Committees except the Cabinet Committee on Accommodation and the Cabinet Committee on Parliamentary Affairs are headed by the Prime Minister.
There are 8 Cabinet committees at present —
Appointments Committee of the Cabinet (composed of the PM (ex-officio Chairman) and the Minister of Home Affairs),
Cabinet Committee on Economic Affairs (headed by the PM himself),
Cabinet Committee on Political Affairs (headed by the PM),
Cabinet Committee on Investment and Growth,
Cabinet Committee on Parliamentary Affairs,
Cabinet Committee on Employment & Skill Development,
Cabinet Committee on Accommodation, and
Cabinet Committee on Security.
The Committees on Investment and Employment were innovations introduced in 2019 by the Modi government.

Jharkhand CM marked the 124th death anniversary of revolutionary tribal leader “Birsa Munda” by paying his tributes.
Who was Birsa Munda (1875-1900)?
Birsa Munda was born on November 15, 1875, during a period of significant change for his community, the Mundas, residing in the Chotanagpur region of present-day Jharkhand.
Birsa Munda spent his early years travelling with his parents and received primary education under Jaipal Nag.
Inspired by the peaceful Sardari agitation against British rule, Birsa became a prominent leader advocating for tribal rights.
Causes of the Rebellion
Impact of Colonial Policies: Colonial policies, including the Permanent Settlement Act (1793), disrupted traditional land ownership systems, leading to displacement and exploitation of indigenous communities.
Erosion of Khuntkattidar System: The Mundas’ traditional land rights system, known as khuntkatti, was eroded by jagirdars and thikadars, leading to land alienation.
Land Alienation and Exploitation: Non-tribal migration into tribal regions accelerated under British rule, resulting in exploitation through high-interest money lending and forced labour.
Missionary Activity: The spread of education through missionary activities led to increased awareness among tribals, deepening social cleavages but also inspiring movements for tribal reconstruction.
Major Activities:
1. New faith ‘Birsait’ against religious conversion
Having gained awareness of the British colonial ruler and the efforts of the missionaries to convert tribals to Christianity, Birsa started the faith of ‘Birsait’.
Soon members of the Munda and Oraon community started joining the Birsait sect and it turned into a challenge to British conversion activities.
The Mundas called him Dharati Aaba, the father of earth.
2.The Birsa Movement: Ulgulan
The Munda Rebellion was a tribal rebellion led by Birsa Munda in the region south of Ranchi in 1899-1900.
It mainly concentrated in the Munda belt of Khunti, Tamar, Sarwada, and Bandgaon.
The revolt sought to establish Munda Raj and independence, known as Ulgulan or ‘Great Tumult’ by Munda tribals.
The rebellion ended with the suppression by British forces and the death of Birsa Munda.
Significant Outcomes
Impact: Birsa Munda’s mobilization of tribal communities left a lasting legacy, prompting government reforms such as the repeal of the Begar system and the enactment of the Tenancy Act (1903).
His Death: The movement was violently suppressed and Birsa Munda died in jail on 9 June 1900.
What is Permanent Settlement System?
The Permanent Settlement system introduced by Lord Cornwallis in 1793 was a land revenue system implemented in British India, particularly in Bengal, Bihar, and Odisha.
Under this system, the land revenue to be paid by the peasants (ryots) was fixed permanently without revision for an extended period (typically 10 years or more).
This fixed amount was based on the estimated productive capacity of the land.
It established the Zamindari system, where Zamindars (landlords) were recognized as the owners of land.
They were responsible for collecting revenue from the peasants and paying it to the British government.
In return, they were entitled to keep a portion of the collected revenue as their income, often ranging from 10% to 15%.

Prelims level: Hydrogen Line and its significance in interstellar studies
Why in the News?
The hydrogen line stands as a pivotal tool in contemporary astronomy, serving various purposes from studying distant stars to questing for extraterrestrial intelligence, should it exist.
What is a Hydrogen Line?
The hydrogen line is a special type of light that hydrogen atoms emit.
It happens when an electron, a tiny particle that orbits the nucleus of the hydrogen atom, jumps from a higher energy level to a lower one.
This jump releases energy in the form of light, specifically with a wavelength of about 21 centimetres. This wavelength is what scientists call the hydrogen line.
Why is it Important?
Hydrogen is everywhere in the universe. It’s the simplest and most abundant element, making up about 75% of the universe’s elemental mass.
So, studying the hydrogen line allows us to understand a lot about the composition and distribution of matter in the universe.
By observing the hydrogen line’s emission from different regions of space, astronomers can create maps showing where hydrogen gas is located.
Secrets about the early Universe: The hydrogen line also holds secrets about the early universe. Shortly after the Big Bang, the universe was filled with hydrogen gas.
By studying the hydrogen line from distant parts of the universe, astronomers can learn about its conditions and evolution billions of years ago.
How Do We Interpret Hydrogen Line?
Radio telescope data enables mapping of hydrogen distribution, revealing locations of hydrogen clouds crucial for understanding galaxy and galaxy cluster formation and evolution.
Observing hydrogen line emission from different galaxy parts enables studying internal structures and dynamics, like rotation curves, offering insights into mass distribution within galaxies.
Observing hydrogen lines from distant galaxies unveils early universe conditions, aiding in understanding cosmic evolution’s initial stages.
What’s Next?
New Discoveries: Scientists are continually developing new technologies and techniques to improve the sensitivity and resolution of radio telescopes.
This enables them to detect fainter signals and uncover new insights into the universe’s hydrogen content.
Exploring Dark Matter: The hydrogen line observations could also contribute to understanding dark matter, an invisible substance that makes up about 27% of the universe’s total mass-energy content.
By studying the hydrogen distribution in relation to the gravitational effects observed in galaxies, scientists hope to shed light on the nature of dark matter.

The initiative falls under Mode 2A of the Strategic Interventions for Green Hydrogen Transition (SIGHT) Programme, part of the National Green Hydrogen Mission led by the Ministry of New & Renewable Energy (MNRE).
What is Green Ammonia?
Green ammonia, also known as renewable ammonia, is a form of ammonia produced using renewable energy sources, which is proposed as a sustainable, emission-free alternative with a multitude of applications in industry and other sectors.
It is produced by combining nitrogen with hydrogen, which is generated through water electrolysis using renewable energy, and then reacting the hydrogen and nitrogen at high temperatures and pressures to form ammonia.
About the National Green Hydrogen Mission
The National Green Hydrogen Mission was launched in January 2023.
Objective: To make India a ‘global hub’ for using, producing and exporting green hydrogen.
Earlier, the National Hydrogen Mission was launched on August 15, 2021, with a view to cutting down carbon emissions and increasing the use of renewable sources of energy.
The Ministry of New and Renewable Energy (MNRE) formulates the scheme guidelines for the implementation of these missions.
Key features of the NGHM
Power capacity: The mission seeks to promote the development of a green hydrogen production capacity of at least 5 MMT per annum with an associated renewable energy capacity addition of about 125 GW in the country by 2030.
Job creation: It envisages an investment of over ₹8 lakh crore and creation of over 6 lakh jobs by 2030.
Reducing energy import bill: It will also result in a cumulative reduction in fossil fuel imports of over ₹1 lakh crore and abatement of nearly 50 MMT of annual greenhouse gas emissions by 2030.
Export promotion: The mission will facilitate demand creation, production, utilisation and export of green hydrogen.
Incentivization: Under the Strategic Interventions for Green Hydrogen Transition Programme (SIGHT), distinct financial incentive mechanisms are provided.
Green Hydrogen Hubs: Regions capable of supporting large-scale production and/or utilisation of hydrogen will be identified and developed as Green Hydrogen Hubs.
What is the SIGHT Program?
In the initial stage, two distinct financial incentive mechanisms proposed with an outlay of ₹ 17,490 crore up to 2029-30:
Incentive for manufacturing of electrolysers
Incentive for production of green hydrogen.
Depending upon the markets and technology development, specific incentive schemes and programmes will continue to evolve as the Mission progresses.

Prelims level: Aboriginals in Andaman and Nicobar Islands, PVTGs
Why in the news?
The king and queen of the “Onge tribe” welcomed a baby boy in the Andaman Islands, marking a significant moment for the tribe. With the arrival of the newborn, the tribe’s total population now stands at 136, as confirmed by an official source.
About Onge Tribe
The Onge are PVTGs (Particularly Vulnerable Tribal Groups) native to the Andaman Islands.
They have traditionally been hunter-gatherers and fishers, while also practising cultivation.
Their population significantly decreased after colonization, from 672 in 1901 to around 100.
They practice a form of animism, with ancestor worship being significant.
They traditionally make decisions through group consensus.
Today, the surviving members are confined to two reserve camps on Little Andaman: Dugong Creek in the northeast, and South Bay.
Genetically, the Onge are distantly related to East Asian populations and show affinities with Southeast Asian Negrito ethnic groups.
Other Indigenous People of Andaman and Nicobar
1. Great Andamanese Tribe
One of the largest tribes, the Great Andamanese tribe is currently settled on the Strait Island under the Andaman & Nicobar Administration. Despite their historic bravery, diseases and other challenges have reduced their population to 43 individuals as of the 2001 census.
Government initiatives: The administration provides housing, coconut plantations, and rationing to support their livelihoods and well-being.
2. Jarwas Tribe
Jarwas inhabit the Western coast of the Middle and South Andaman Islands. They are known to be hostile but have shown receptivity to friendly contact expeditions since 1974. Their present numbers are estimated at between 250–400 individuals.
Jarwas are nomadic hunters and gatherers, using traditional methods like bows and arrows for hunting and fishing.
3. Sentinelese Tribe
Sentinelese reside on the small North Sentinel Island, maintaining a wary stance towards outsiders.
Despite initial scepticism, contact expeditions have made progress since 1991, albeit with caution.
Who are the Particularly Vulnerable Tribal Groups (PVTGs)?
These groups are among the most vulnerable sections of our society as they are few in number, and have not attained any significant level of social and economic development.
They generally inhabit remote localities having poor infrastructure and administrative support.
75 such groups have been identified and categorized as Particularly Vulnerable Tribal Groups (PVTGs).
Origin of the concept
The Dhebar Commission (1960-1961) stated that within Scheduled Tribes there existed an inequality in the rate of development.
During the fourth Five Year Plan (1969-74) a sub-category was created within Scheduled Tribes to identify groups that were considered to be at a lower level of development.
This sub-category was named “Primitive tribal group”.
In 2006 the government of India proposed to renamePVTGs.
Features of PVTGs
The features of such a group include a:
Pre-agricultural system of existence
The practice of hunting and gathering
Zero or negative population growth
Extremely low level of literacy in comparison with other tribal groups
Groups that satisfied any one of the criteria were considered PTG.
PYQ:
[2019] Consider the following statements about Particularly Vulnerable Tribal Groups (PVTGs) in India:
PVTGs reside in 18 States and one Union Territory.
A stagnant or declining population is one of the criteria for determining PVTG status.

Prelims level: H5N2 , Avian Influenza A
Why in the News?
The World Health Organization (WHO) has confirmed the death of a Mexican resident due to bird flu, marking the first confirmed case of human infection with the H5N2 variant.
This H5N2 strain is different from another bird flu variety-H5N1 which infected people in America recently.
What is Avian Influenza A (H5N2)?
Avian Influenza A (H5N2) is a subtype of the influenza A virus that primarily circulates among birds but can infect humans under certain circumstances.
Human infections typically result from direct contact with infected birds or contaminated environments, showcasing the zoonotic nature of the virus.
Symptoms of H5N2
Infection of H5N2 may cause mild to severe upper respiratory tract infections and can be fatal.
Conjunctivitis, gastrointestinal symptoms, encephalitis and encephalopathy have also been reported.
Diagnostic and Treatment Protocols
Laboratory Diagnosis: The identification of avian influenza in humans necessitates laboratory testing to confirm the presence of the virus.
WHO Guidance: The World Health Organization periodically updates technical protocols, such as RT-PCR methods, to enhance the detection of zoonotic influenza.
Treatment Strategies: Antiviral medications, notably neuraminidase inhibitors like oseltamivir and zanamivir, demonstrate efficacy in reducing viral replication duration and improving survival prospects for afflicted individuals.
Influenza A Viruses
The alphanumeric codes of H and N are used to subdivide the viruses according to what kinds of proteins are on the surface of the virus based on 2 types:
Hemagglutinin (HA)
Neuraminidase (NA)
There are 18 known HA subtypes and 11 known NA subtypes.
In birds, 16 HA and 9 NA subtypes have been identified. (Two additional subtypes, H17N10 and H18N11, have been identified in bats.)
Many different combinations of HA and NA proteins are possible.
For example, an “A(H7N2) virus” designates an influenza A virus subtype that has an HA 7 protein and an NA 2 protein.
Similarly, an “A(H5N1)” virus has an HA 5 protein and an NA 1 protein.
