About Vijaipur Green Hydrogen Plant
The plant aligns with the National Green Hydrogen Mission‘s objective of achieving 5 million tons of annual green hydrogen production capacity by 2030.
The plant features a 10-megawattproton exchange membrane electrolyser imported from Canada.
It will produce approximately 4.3 tonnes of green hydrogen per day with a purity of about 99.999% by volume.
The production process utilises electricity from renewable sources, such as solar energy, to split water and produce green hydrogen.
Major Objective: Hydrogen Blending
GAIL is currently conducting experimental blending of hydrogen with natural gas.
Current regulations permit blending up to 5% hydrogen with natural gas, with ongoing studies to explore higher blending ratios.
What is Green Hydrogen?
Green hydrogen is produced through electrolysis, where electricity derived from renewable sources, such as solar or wind power, is used to split water molecules into hydrogen and oxygen.
Since it relies on renewable energy, green hydrogen production has no direct emissions of CO2 or other greenhouse gases.
What is the Green Hydrogen Standard?
Definition of Green Hydrogen: It has defined green hydrogen as having a well-to-gate emission – including water treatment, electrolysis, gas purification, drying and compression of hydrogen – of not more than 2 kg CO2 equivalent per kg of hydrogen produced.

Prelims level: Cost Inflation Index (CII); Long Term Capital Gains
Why in the News?
The Income Tax Department has notified the cost inflation index (CII) for the current fiscal to calculate long-term capital gains arising from the sale of immovable property, securities and jewellery.
The CII is used by a taxpayer to compute gains arising out of the sale of capital assets after adjusting for inflation.
CII Values:
For FY 2024-25, the CII is set at 363.
Previous years’ CII values were 348 for FY 2023-24 and 331 for FY 2022-23.
What isCost Inflation Index (CII)?
CII is a measure used by the Income Tax Department of India to account for inflation when calculating the capital gains on the sale of long-term capital assets.
It helps to adjust the purchase price of assets to reflect the effect of inflation.
CII adjusts the cost of acquisition of assets to the price level inflation at the time of sale.
This ensures that taxpayers pay taxeson the real gains rather than on the inflationary component of the price rise.
It is defined under Section 48 of the Income-tax Act, 1961.
The index is revised annually to keep up with inflation, with the base year being periodically reset (currently the base year is 2001-02 in India).
Application of CII
CII is used to compute the indexed cost of acquisition of a capital asset that has been held for more than36 months (considered as long-term capital assets).
Different holding periods apply for certain types of assets like immovable property and listed securities.
Tax Calculation:
The formula used is:
This formula helps determine the adjusted cost basis from which any sale proceeds are subtracted to calculate capital gains.
Back2Basics: Long Term Capital Gains
In India, long-term capital gains (LTCG) refer to the profit earned from the sale of a capital asset held for a specific period, qualifying it as “long-term” based on the duration of holding.
The tax implications and treatment of these gains are distinct from those of short-term capital gains.
Definition of Long-Term Capital Assets
Equity or Preference Shares, Listed Securities, Units of UTI, etc.: These are considered long-term if held for more than 12 months before sale.
Immovable Property (e.g., Land, Building): Considered long-term if held for more than 24 months.
Other Assets (e.g., Jewellery, Debt-oriented Mutual Funds, etc.): These need to be held for more than 36 months to be considered long-term.
Taxation of Long-Term Capital Gains
Equity Investments:
LTCG from the sale of listed shares or equity-oriented mutual funds over ₹1 lakh is taxed at 10% without the benefit of indexation, provided the securities transaction tax (STT) was paid at the time of sale.
Non-Equity Investments:
LTCG from assets like debt mutual funds, real estate, gold, etc., is taxed at 20% with the benefit of indexation.
Indexation Benefit:
For non-equity assets, the Cost Inflation Index (CII) is used to adjust the purchase price of the asset to reflect inflation. This reduces the taxable gain by increasing the acquisition cost.
Calculation of Long-Term Capital Gains
The general formula for calculating LTCG is:
Where:
Full Value of Consideration is the sale price of the asset.
Indexed Cost of Acquisition is the purchase price adjusted by the CII.
Indexed Cost of Improvement refers to the cost of any improvements made to the asset, adjusted by the CII.
Cost of Transfer includes expenses directly related to the sale or transfer of the asset.
Exemptions and Deductions
Section 54: Exemption on LTCG from the sale of a residential property if the proceeds are reinvested in another residential property in India.
Section 54EC: Exemption by investing LTCG in bonds issued by NHAI or REC within 6 months of the asset sale, subject to a cap of ₹50 lakhs.

Prelims level: Fatty Acids and their health implications
Why in the News?
Fish oil supplements, highly regarded for their high omega-3 fatty acid content, have long been associated with heart health benefits.
A recent study has caused controversy by raising the possibility that these supplements may be as harmful as previously thought.
What are Fatty Acids?
Fatty acids are crucial lipids (fats and oils) essential for various biological functions (Fatty Acid + Glycerol = Fats). They are carboxylic acids with a long aliphatic chain, either saturated or unsaturated.
Basic Structure: Consists of a hydrocarbon chain with a terminal carboxyl group (-COOH). The length and degree of saturation of the hydrocarbon chain can vary.
Roles in the Body: Serve as energy sources, components of cell membranes, and precursors for bioactive lipids.
Types of Fatty Acids
Fatty acids are classified based on the presence and number of double bonds in their hydrocarbon chain:
Saturated Fatty Acids (SFA)
Structure: Contain no double bonds between carbon atoms; the hydrocarbon chain is saturated with hydrogen atoms.
Formation: Produced by the industrial process of hydrogenation of unsaturated fats, or naturally in the guts of some animals.
Properties: Similar to saturated fats, solid at room temperature.
Health Impact: Associated with negative cardiovascular effects.
Sources: Margarine, partially hydrogenated oils, and some baked goods.
What are Omega-3 Fatty Acids?
Omega-3 fatty acids (omega-3s) are polyunsaturated fats that perform important functions in the human body.
There are three main types of omega-3 fatty acids:
EPA (eicosapentaenoic acid). EPA is a “marine omega-3” because it’s found in fish.
DHA (docosahexaenoic acid). DHA is also a marine omega-3 found in fish.
ALA (alpha-linolenic acid). ALA is the form of omega-3 found in plants.
When we get ALA from food, the human body can turn some of the ALA into EPA and subsequently to DHA. However, this process provides just a small amount of EPA and DHA. So, dietary sources of EPA and DHA (like fish) are essential.
Functions of Omega-s fatty acids:
They help to provide structure and supporting interactions between cells.
Omega-3s are concentrated in high levels in cells in human eyes and brain.
They provide the human body with energy (calories) and support the health of many body systems. These include the human cardiovascular system and endocrine system.
Significance of Omega-3 fatty acids:
Omega-3 fatty acids have many potential benefits for human cardiovascular health.
One key benefit is that they help lower human triglyceride levels.
Too many triglycerides in human blood (hypertriglyceridemia) raise human risk of atherosclerosis, and through this, can increase human risk of heart disease and stroke. So, it’s important to keep triglyceride levels under control.
Omega-3s may help us by raising human HDL (good) cholesterol and lowering human blood pressure.
Some studies show omega-3s may lower human risk for Cardiovascular disease (CVD), and hence lowering the sudden death caused by an abnormal heart rhythm (arrhythmia), and blood clots.
Beyond heart health, omega-3s may help lower the human risk of developing some forms of cancer, including breast cancer, Alzheimer’s disease, and dementia, age-related macular degeneration (AMD), research continues to investigate these and other possible benefits.
PYQ:

Prelims level: Adenovirus, herpesvirus, and papillomavirus
Mains level: NA
Why in the News?
Researchers found traces of many present-day viruses in the bones of two Neanderthals who lived 50,000 years ago, providing a new perspective on their extinction.
Breakthrough Study on Neanderthals
Ancient viruses in Neanderthal DNA samples from skeletons found in Russia’s Chagyrskaya cave.
The study detected fragments resembling three modern viruses: adenovirus (common colds), herpesvirus (cold sores), and papillomavirus (genital warts).
Health Impacts Inherited in Modern Human Beings:
Modern humans inherit various health impacts from Neanderthals, including skin conditions, allergies, metabolism, nicotine addiction, mood disorders, sleep patterns, blood clotting, sense of smell, and UV radiation response.
Who were the Neanderthals?
Neanderthals were a distinct species of hominins that lived in Europe and parts of Asia around 400,000 to 40,000 years ago during the Middle to Late Pleistocene Epochs.
Their evidence was first found in 1856 in the Neander Valley in present-day Germany.
Physical Features:
Neanderthals were robustly built, with a stocky and muscular frame adapted to cold climates.
They had large brains, comparable in size to modern humans, indicating advanced cognitive abilities.
Distinctive features included a prominent brow ridge, large nose, and a receding chin.
Social Life:
Neanderthals were skilled hunters and gatherers, using tools such as stone flakes, scrapers, and spears for hunting and butchering animals.
They utilized fire for cooking, warmth, and protection, as evidenced by the presence of hearths in their archaeological sites.
Evidence suggests they had complex social structures and engaged in rituals and symbolic behaviours, including burying their dead with grave goods.
Habitat and Distribution:
Neanderthals inhabited a wide range of environments, including open grasslands, forests, and even cold tundra regions.
Their range extended from Western Europe to Central Asia, with evidence of populations in regions such as Spain, France, Germany, Croatia, and the Middle East.
Interactions with Modern Humans:

Prelims level: Ferroptosis
Mains level: NA
Why in the News?
Columbia University study on COVID-19 fatalities found ferroptosis as the main cause of lung cell death, advancing understanding of lung disease development.
What is Ferroptosis?
Ferroptosis is a type of regulated cell death characterized by the iron-dependent accumulation of lipid peroxides to lethal levels.
Other forms of cell death:
Apoptosis (highly regulated process that occurs in multicellular organisms to eliminate unwanted or damaged cells without causing inflammation),
Necrosis (cell death characterized by rapid and uncontrolled cell lysis, often accompanied by inflammation and tissue damage).
Autophagy (involves the degradation and recycling of cellular components through lysosomal machinery).
Mechanism of Ferroptosis:
The precise molecular mechanism underlying ferroptosis is still being elucidated, but it involves the deregulation of iron metabolism and lipid peroxidation. Here’s a simplified overview of how ferroptosis occurs:
Iron Accumulation: Ferroptosis is characterized by the accumulation of iron within cells, particularly in the form of labile iron pools. Excess iron can lead to the generation of reactive oxygen species (ROS) through Fenton chemistry.
Lipid Peroxidation: ROS generated from excess iron promotes lipid peroxidation, particularly of polyunsaturated fatty acids (PUFAs) within cell membranes. Lipid peroxides accumulate and propagate, leading to membrane damage and loss of membrane integrity.
Glutathione Depletion: Glutathione (GSH) is an antioxidant that helps to neutralize ROS and prevent lipid peroxidation. In ferroptosis, there is a depletion of cellular GSH levels, which impairs the cell’s ability to counteract oxidative stress.
GPX4 Inhibition: Glutathione peroxidase 4 (GPX4) is an enzyme that catalyzes the reduction of lipid hydroperoxides to their corresponding alcohols, thereby protecting cells from lipid peroxidation. In ferroptosis, GPX4 activity is inhibited, leading to the accumulation of lipid peroxides and cell death.
Mitochondrial Dysfunction: Ferroptosis is associated with mitochondrial dysfunction, including alterations in mitochondrial membrane potential and morphology, as well as disruption of mitochondrial metabolism and bioenergetics.
Cellular Consequences: The accumulation of lipid peroxides and mitochondrial dysfunction ultimately leads to cellular damage, loss of cell membrane integrity, and cell death by ferroptosis.
Significance of the Study
Targeting and preventing ferroptosis could offer novel treatment avenues for COVID-19 lung disease and its possible future mutations.
Inhibiting this form of cell death may help improve the treatment outcomes for severe cases of COVID-19.

Prelims level: Tropical Cyclone
Mains level: NA
Why in the News?
Cyclone Remal is forecasted to make landfall between Sagar Island in West Bengal and Bangladesh’s Khepupara on Sunday midnight.
The name ‘Remal’ originates from Oman and means ‘sand’ in Arabic.
What are Cyclones?
Cyclones are wind systems rotating inwardly towards an area of low atmospheric pressure. They are categorised into Tropical (Temperature-induced) and Temperate (extra-tropical) cyclones(airmass-induced).
Formation Conditions: Tropical cyclones originate in warm regions, requiring conditions such as
Warm sea surface (> 27°C),
Coriolis Force,
Pre-existing low-pressure systems,
Small vertical wind speed differences, and
Upper air divergence.
Characteristics of Tropical Cyclones:
Theyform over warm water bodies due to energy derived from the condensation of warm water within cumulonimbus clouds.
Wind rotation is influenced by the Coriolis force, resulting in anti-clockwise rotation in the northern hemisphere and clockwise in the southern hemisphere.
Regional Movement of Cyclones:
In the northern hemisphere, cyclones initially move westward under earth rotation and the Easterlies.
As they progress towards higher latitudes, the Coriolis force deflects them rightward, towards north and later east.
By 30° latitude, the diminished warmth halts cyclone activity.
Naming of Cyclones:
Responsibility of RSMCs and TCWCs: The naming of cyclones that form in every ocean basin across the world is carried out by the Regional Specialised Meteorological Centres (RSMCs) and Tropical Cyclone Warning Centres (TCWCs).
Procedure in the North Indian Ocean: For north Indian Ocean including Bay of Bengal and Arabian Sea, the RSMC, New Delhi assigns the name to tropical cyclones following a standard procedure.
Agreement by WMO/ESCAP Panel: The WMO/ESCAP Panel on Tropical Cyclones in 2000 agreed in principle to assign names to the tropical cyclones in the Bay of Bengal and Arabian Sea.
Selection Process: Each country would sent their suggestions, based on which the Panel would finalise a list.
Retirement of Names: Generally, names of some storms that cause widespread damage and deaths are usually retired and are not brought back or reused later, at least for 10 years. These names are then replaced with new names.
Unique Policy for North Indian Ocean: Unlike in other regions, the names of tropical cyclones over the north Indian Ocean once used, will cease to be used again.
Destruction Caused by Cyclones:
Strong Winds/Squall: Cyclones cause infrastructure damage through high-speed winds.
Torrential Rains and Inland Flooding: Heavy rainfall leads to floods, soil erosion, and embankment weakening.

Back2Basics: United Nations Peacekeeping
UN Peacekeeping is a collective effort by the international community, led by the United Nations, to maintain peace and security in regions affected by conflict.
UN peacekeepers are often referred to as Blue Berets or Blue Helmets because of their light blue berets or helmets) can include soldiers, police officers, and civilian personnel.
History:
The concept of UN peacekeeping emerged in the aftermath of World War II, with the establishment of the United Nations in 1945.
The first UN peacekeeping mission was established in 1948, following the Arab-Israeli War, to monitor the ceasefire between Israel and its Arab neighbours.
This mission, known as the United Nations Truce Supervision Organization (UNTSO), set the precedent for future peacekeeping operations.
Since then, the scope and complexity of UN peacekeeping have evolved significantly, with operations conducted across the globe in regions affected by conflict, civil war, and humanitarian crises.
Operations:
UN Peacekeeping is guided by three basic principles:
Consent of the parties
Impartiality
Non-use of force except in self-defence and defence of the mandate
UN peacekeeping operations are deployed with the consent of the main parties to the conflict. It can be deployed at the request of the partiesinvolved in a conflict or with the authorisation of the UN Security Council.
The objectives may vary depending on the specific context but often include monitoring ceasefires, disarming combatants, facilitating the delivery of humanitarian aid, promoting human rights, and supporting the establishment of democratic governance structures.
UN peacekeeping operations operate under the principles of impartiality, consent of the parties, and non-use of force except in self-defence and defence of the mandate.
India’s Role:
India has been one of the largest contributors to UN peacekeeping operations since their inception.
India has contributed nearly 195,000 troops, the largest number from any country, and participated in more than 49 missions and 168 supreme sacrifices while serving in UN missions.

Mains level: Significance of BIMSTEC for all member countries;
Why in the News?
The Ministry of External Affairs has announced that with the establishment of its inaugural charter on May 20th, the Bay of Bengal Initiative for Multi-Sectoral Technical and Economic Cooperation (BIMSTEC) will now accept new members and observers.
About BIMSTEC:
The Bay of Bengal Initiative for Multi-Sectoral Technical and Economic Cooperation (BIMSTEC) formed in 1997 is a multilateral regional organization comprising seven member states: Bangladesh, Bhutan, Sri Lanka, Nepal, Thailand, Myanmar, and India.
Aim: To promote technical and economic cooperation among its member countries, particularly in sectors such as security, connectivity, trade, agriculture, environment, science and technology, and people-to-people contact.
Adoption of the Charter:
After years of deliberation, the BIMSTEC leaders adopted the organization’s first charter during their 5th summit.
This charter provides a legal framework for the group, granting it a “legal personality” and enabling the structured diplomatic dialogue with other countries and regional groupings.
In the context of international organizations like BIMSTEC, obtaining legal personality means that the organization is recognized as a legal entity in its own right, separate from its member states.
Significance of BIMSTEC for all member countries:
The charter’s implementation enhances cooperation and deeper integration within the Bay of Bengal region, benefiting all member states economically and strategically.
Enhanced Cooperation: With the charter in place, member countries can engage in more structured and organized cooperation across various sectors such as security, connectivity, trade, agriculture, environment, science and technology, and people-to-people contact.
Strengthened Regional Integration: The charter facilitates deeper integration within the Bay of Bengal region. By establishing common goals and mechanisms for cooperation, it promotes economic growth, social development, and cultural exchange among member countries.
Diplomatic Dialogue: The charter enables BIMSTEC to enter into structured diplomatic dialogue with other countries and regional groupings. This opens up avenues for broader engagement and partnership, enhancing the geopolitical significance of the BIMSTEC platform.
Challenges in the present world context:
Historical Discord: Long-standing historical discord between member states, such as Bangladesh and Myanmar, presents a challenge to cohesive cooperation within BIMSTEC. These tensions can hinder progress on joint initiatives and impede the organization’s effectiveness.
Geopolitical Complexities: Geopolitical complexities, exacerbated by events like the Rohingya refugee crisis and the coup in Myanmar, add layers of complexity to regional dynamics.
These complexities can strain relationships between member states and complicate efforts to foster collaboration and integration within BIMSTEC.
Stagnation of SAARC: While BIMSTEC offers an alternative platform for regional cooperation, the near stagnation of SAARC underscores the challenges faced by regional organizations in fostering meaningful collaboration.
Way forward:
Need a Conflict Resolution Mechanisms: Implement effective conflict resolution mechanisms to address historical discord and tensions between member states.
High Diplomatic Engagement: Encourage regular diplomatic engagement and dialogue between member states to address geopolitical complexities and build trust.
Mains PYQ
Q Do you think that BIMSTEC is a parallel organization like the SAARC? What are the similarities and dissimilarities between the two? How are Indian foreign policy objectives realized by forming this new organization? (UPSC IAS/2022)

Prelims level: Xenotransplantation, Crispr-Cas9
Mains level: NA
Why in the News?
The recent passing away of Richard Slayman, the first recipient of a modified pig kidney transplant, has drawn attention to xenotransplantation—an innovative medical procedure with the potential to revolutionise organ transplantation.
What is Xenotransplantation?
It involves transplanting live cells, tissues, or organs from nonhuman animal sources into human recipients.
It seeks to address the critical gap between organ demand and supply.
Xenotransplantation, pioneered in the 1980s with heart transplants, has emerged as a promising solution to alleviate the organ shortage crisis, particularly prevalent in kidney transplantation.
Examples:
Chimpanzee-to-Human Transplants: In the 1960s, there were attempts at chimpanzee-to-human kidney transplants, heart transplants, and liver transplants.
Pig-to-Human Heart Transplant: In 2022, a groundbreaking milestone was achieved with the first successful transplantation of a pig heart into a human with end-stage heart disease
Procedural Details
Xenotransplantation involves genetic modifications to animal organs, like 69 CRISPR-Cas9 edits to a pig kidney, removing pig genes and adding human genes for compatibility.
Why is the Pig a Preferred Source?
Anatomical Resemblance: Pigs are favoured for xenotransplantation due to their physiological similarities to humans, facilitating successful integration. Pig organs, like heart valves, have been used in human medicine for over 50 years.
Breeding Advantages: Extensive pig farming ensures a readily available and cost-effective supply of organs, with diverse breeds offering size-matching opportunities.
Challenges associated
The main challenge is preventing organ rejection. Innovative methods, such as embedding the pig’s thymus gland under the kidney’s outer layer, help manage immune responses.
There are also significant concerns regarding potential infections from both recognised and unrecognised infectious agents that could affect not only the recipient but also the wider population.
Retroviruses present in the animal organs pose a risk of cross-species infection, which could remain latent and cause diseases years after the transplantation.

Prelims level: ICAI, Tax Audit
Mains level: NA
Why in the News?
The Supreme Court upheld a rule issued by the Institute of Chartered Accountants of India (ICAI) that limits Chartered Accountants to accepting no more than 60 tax audit assignments in a financial year.
The court found that the rule does NOT violate the fundamental right to practice a profession under Article 19(1) (g) of the Constitution (apart from also being violative of the right to equality under Article 14).
Tax Audit Regime: A Quick Backgrounder
The mandatory tax audit regime was initiated in 1984 with Section 44AB in the Income Tax Act, of 1961 which required certain businesses and professionals to get their accounts audited.
Tax Audit aims to ensure compliance with the provisions of the Income Tax Act, 1961, and detect and prevent tax evasion and fraud.
In 1988, the ICAI limited Chartered Accountants to a specified number of tax audit assignments to ensure quality and reduce the risk of misconduct.
This limit was part of the guidelines issued in 2008, which replaced previous notifications and were challenged in various High Courts.
