Recently, the Indian government signed a contract with the International Seabed Authority to explore polymetallic sulphur nodules in the Carlsberg Ridge.
The Carlsberg Ridge is a mid-oceanic ridge located in the Indian Ocean. It is a divergent plate boundary, where tectonic plates are moving apart.
Location: It extends from the triple junction of the African, Indian, and Australian tectonic plates, which is where it connects with the Mid-Indian Ridge. It runs northwest toward the Gulf of Aden.
Geographic Separation: The ridge separates the Arabian Sea to the northeast from the Somali Basin to the southwest.
Tectonic Boundary: It marks the boundary between the Somali Plate and the Indian Plate.
Depth: The ridge has a mean depth between 6,000 to 12,000 feet (1,800 to 3,600 meters) below the sea surface, though some areas of the ridge rise to a mean elevation of about 7,000 feet (2,100 meters) above the seafloor.
Geological Significance: The Carlsberg Ridge is the most prominent mid-ocean ridge segment in the western Indian Ocean and contains numerous earthquake epicenters.
Connection with Other Geological Features: It turns westward around the island of Socotra and eventually links to the East African Rift System through the Gulf of Aden.
The exploration of polymetallic sulphur nodules in the Carlsberg Ridge is a significant development. These nodules are rich in precious metals such as nickel, copper, and cobalt, which are essential for various high-tech applications, including electric vehicle batteries and renewable energy systems.
The International Seabed Authority (ISA) governs the exploration and exploitation of these seabed resources in international waters. This agreement will enable India to explore these valuable mineral resources in the Indian Ocean.
The Supreme Court of India recently ruled that a State Government cannot invoke the doctrine of escheat under Section 29 of the Hindu Succession Act once a Hindu male has executed a Will that has been declared valid and has been granted probate by a court. This ruling clarifies the legal implications of escheat in the presence of a valid will.
The doctrine of escheat is a significant legal principle ensuring that no property remains without ownership. If the original owner dies without legal heirs or fails to create a Will, the property reverts to the State.
Intestate Succession: When a person dies without a will (intestate) and without legal heirs, the property escheats to the state.
Unclaimed Property: When property is unclaimed or abandoned for a specific period, it can also escheat to the state.
The primary goal of escheat is to ensure that property does not remain ownerless. In the absence of heirs, the government assumes ownership, thereby preventing the property from being misused or left in legal limbo.
The doctrine of escheat has its roots in medieval Europe during the feudal system. Here's a quick look at its evolution:
The term "escheat" comes from the Old French word "eschete," meaning "to fall to."
Under feudalism, land held by tenants would revert (or escheat) to the lord if the tenant died without heirs or was convicted of certain crimes, like treason.
Over time, the concept evolved, and in modern legal systems, it is the state rather than the lord or monarch that assumes ownership of the land or property.
In modern legal systems, escheat ensures that property is not left ownerless. It also serves as a mechanism for handling unclaimed assets.
In India, Section 29 of the Hindu Succession Act, 1956 and Article 296 of the Indian Constitution govern the doctrine of escheat.
These provisions specify the circumstances under which property escheats to the state. The state temporarily or permanently assumes control of unclaimed or abandoned property.
The Supreme Court ruling has reinforced that the doctrine of escheat is only applicable when a person dies intestate (without a will) and without any legal heirs. If there is a valid will that has been probated, the property must pass to the beneficiaries as per the testator's intent, without any interference from the state.
This ruling reaffirms the importance of testamentary freedom — that is, the right of individuals to decide the disposition of their property after death through a Will. If a person has executed a valid will and it has been probated, the estate must follow the testator’s wishes, and the state cannot assert any claim over the property.

India's Institute for Plasma Research (IPR) in Gandhinagar has recently proposed a comprehensive roadmap for the development of fusion power, marking a significant leap towards harnessing fusion energy as a potential solution to the country's growing energy needs.
The central element of this roadmap is the development of the Steady-state Superconducting Tokamak-Bharat (SST-Bharat) reactor, a critical next step in India's long-term energy strategy. This development holds the promise of contributing significantly to India’s energy mix in the future, and could position the country as a global leader in clean energy technologies.
Fusion is the process where two light atoms, usually hydrogen isotopes, come together to form a heavier atom, releasing vast amounts of energy. This process is the same one that powers the Sun and other stars.
Fusion in the Sun: In the Sun, hydrogen nuclei fuse to form helium, releasing energy in the form of light and heat.
Energy Release: The energy comes from the mass defect — the mass of the resulting atom is slightly less than the sum of the masses of the two original atoms. According to Einstein's theory of special relativity (E=mc²), this mass is converted into energy.
High Temperature: Around 100 million°C.
High Pressure: To bring atomic nuclei close enough to fuse.
Plasma State: The material is in a high-energy state where atoms break into ions and electrons.
Fission splits heavy atoms like uranium into smaller nuclei, releasing energy, while fusion combines light atoms to release energy.
Fusion is seen as a cleaner alternative, producing less radioactive waste and offering greater sustainability.
India’s journey towards fusion energy is advancing, with the SST-Bharat reactor set to be a key player. Here's a look at the current capabilities and future goals:
India’s Steady State Superconducting Tokamak (SST-1) at IPR has already achieved plasma confinement for 650 milliseconds. This is a significant achievement, though SST-1 is primarily an experimental device, not designed for electricity generation.
International Collaboration: India is an active participant in the International Thermonuclear Experimental Reactor (ITER) project in France, aiming to achieve a Q value of 10 (meaning it produces 10 times the energy it consumes).
The SST-Bharat reactor will aim to be a fusion-fission hybrid reactor with a target output of 130 MW and a Q value of 5 in its early stages.
A full-scale demonstration reactor is planned to be commissioned by 2060, with an ambitious target of 250 MW output and a Q value of 20, which would mark a breakthrough in sustainable fusion power generation.
Digital Twins: Virtual replicas of tokamaks to simulate and test design conditions.
Machine Learning: AI and machine learning will help predict and manage plasma behavior for better containment.
Radiation-Resistant Materials: Research is focused on developing materials that can withstand extreme radiation inside fusion reactors.
Superconducting Magnets: High-performance superconducting magnets will be used to create stronger magnetic fields, crucial for plasma confinement.
United Kingdom: The UK STEP programme aims to prototype a fusion power plant by 2040.
United States: Private companies claim they will deliver grid-connected fusion power by the 2030s.
China: The Experimental Advanced Superconducting Tokamak (EAST) has already set records for plasma holding duration (1,066 seconds).
India’s roadmap faces several challenges:
High Costs: Fusion research requires significant investment in advanced technology, infrastructure, and reactors.
Long Development Timeline: India’s target of 2060 for a fusion reactor is slower than global efforts, especially compared to China and the US, which are progressing at a faster pace.
Limited Private Sector Involvement: India's private sector is less involved in fusion research, unlike in the US and Europe, where private companies are key players.
Technological Hurdles: Key challenges include plasma containment, achieving a positive Q value, and developing radiation-resistant materials.
Competition with Other Energy Sources: Fusion will compete with solar, wind, and nuclear fission, all of which are rapidly advancing technologies.
Uncertain Commercial Viability: Even if fusion succeeds, its cost-effectiveness compared to existing energy sources remains uncertain.
India can take several steps to maximize the benefits of its fusion R&D:
Policy and Funding Support: Providing long-term, mission-mode funding, similar to India's space and nuclear fission programs (e.g., ISRO).
Private Sector Partnerships: Encouraging the private sector, especially in AI, advanced materials, and digital simulations, to drive innovation.
Global Collaborations: Expanding collaborations beyond ITER, fostering bilateral partnerships with fusion labs in the US, UK, and the EU.
Realistic Targeting: Viewing fusion as a long-term R&D frontier rather than a near-term energy solution.
Leveraging Fusion R&D: Using fusion research to enhance India's capabilities in key areas like superconducting materials, radiation shielding, and plasma control.
India’s fusion power roadmap is both ambitious and strategic, with SST-Bharat serving as a critical milestone in achieving a clean energy future. While challenges exist, India’s investment in fusion research can yield substantial technological, economic, and strategic benefits, especially as the global demand for clean energy continues to grow. By focusing on innovation, collaboration, and long-term planning, India is positioning itself at the forefront of the global fusion energy race
India's Defence Research and Development Organisation (DRDO) is on the verge of a historic milestone with the upcoming test of Dhvani, a next-generation hypersonic missile that is set to propel India into an elite group of military superpowers.
The Dhvani is a hypersonic glide vehicle (HGV), a revolutionary weapon system that combines extreme speed with unmatched maneuverability. Hypersonic missiles like Dhvani are a game-changer in modern warfare due to their ability to travel at speeds of Mach 5 and beyond (over 6,000 km/h).

Unlike traditional volcanoes, mud volcanoes do not erupt lava but instead release mud slurries that can form cone-like structures.
Formation: Mud volcanoes are formed through tectonic activity, where pressure builds up and causes mud, water, and gas to be expelled through the earth’s crust.
Size: These volcanoes can vary in size, ranging from 1 to 2 meters to 700 meters in height, and can span from 1 to 10 kilometers in width.
Global Presence: Mud volcanoes exist not only on land but also beneath the sea, where they can form underwater banks and islands that alter coastal topography.
While rare in the Indian subcontinent, mud volcanoes are found in various parts of the world:
Azerbaijan: Home to some of the largest mud volcanoes in the world.
Italy: Features mud volcanoes, notably in the Campi Flegrei region near Naples.
USA: In California, mud volcanoes are present in places like Mono Lake.
The mud volcano on Baratang Island continues to be a fascinating natural wonder that attracts both scientific study and tourism. As India’s only active mud volcano, it offers unique insights into the processes of the Earth’s surface and adds to the biodiversity and ecological uniqueness of the Andaman and Nicobar Islands.
Willingdon Island is a prominent man-made island in the Kochi area of Kerala, India, and is regarded as one of the most beautiful locations in the region. It holds a special place in both historical and strategic contexts.
Man-Made Island: Willingdon Island was created by the British during the colonial era and is named after Lord Willingdon, the 22nd Viceroy and Governor-General of India (1931–1936).
Strategic Significance: The island serves as a hub for various important institutions and facilities:
Kochi Naval Base: A key naval base of the Indian Navy, strategically important for the country's defense.
Central Institute of Fisheries Technology (CIFT): Focuses on research and development in the field of fisheries and aquaculture.
Port of Kochi: One of the major ports on the west coast of India, handling a significant volume of international trade.
Connectivity: Willingdon Island is connected to the mainland by the Venduruthy Bridge, which facilitates easy access for both people and goods between the island and Kochi.
Lord Willingdon was the 22nd Viceroy and Governor-General of India, serving from 1931 to 1936. His tenure was marked by several key events that shaped the political landscape of India during British rule.
Government of India Act, 1935:
The Government of India Act was one of the most significant pieces of legislation passed during British rule, which paved the way for the eventual creation of provincial autonomy in India.
It granted limited self-governance to Indians, though it still maintained British control over major areas like defense and foreign affairs.
The Second Round Table Conference (1931):
Held in London, this conference included Mahatma Gandhi as the representative of the Indian National Congress.
The conference aimed to address constitutional reforms in India, though it did not yield a satisfactory solution for full self-rule.
The Communal Award (1932):
British Prime Minister Ramsay MacDonald introduced the Communal Award in 1932, which provided separate electorates for different communities, including Muslims, Sikhs, and other minorities, causing division among the Indian population.
It was a controversial move, as it further entrenched communal identities rather than fostering unity.
The Poona Pact (1932):
The Poona Pact was a historic agreement reached between Mahatma Gandhi and Dr. B.R. Ambedkar to address the issue of representation of backward classes in legislatures.
The pact provided for reserved seats for the depressed classes in the provincial legislatures but allowed them to elect their representatives from a common electoral roll.
The Third Round Table Conference (1932):
This conference was intended to resolve constitutional issues but failed because neither Gandhi nor the Indian National Congress attended. This made the conference largely ineffective in pushing forward the cause of Indian self-rule.
Willingdon Island stands as both a testament to British-era engineering and a modern-day strategic hub in Kochi. Named after Lord Willingdon, its historical significance is tied to key events during British rule, including the Government of India Act, 1935, and the Second and Third Round Table Conferences. Today, it remains a crucial part of Kochi's economic and defense infrastructure, with a deep connection to both the past and the present
Nankana Sahib is one of the most significant and revered cities for the Sikh community. It holds immense historical and spiritual value as it is the birthplace of Guru Nanak Dev Ji, the founder of Sikhism.
Location: Nankana Sahib is located in the Punjab province of Pakistan, approximately 75 kilometers west of Lahore. The city is historically tied to the Sikh faith and remains a major pilgrimage site for Sikhs worldwide.
Historical Background:
Originally known as Rai-Bhoi-Di Talwandi, the city was renamed Nankana Sahib by Rai Bhullar Bhatti, the grandson of the founder Rai Bhoi, in honor of the birth of Guru Nanak.
Guru Nanak spent his early years here, from where he began his divine calling and spiritual journey that eventually led to the establishment of Sikhism.
Gurdwara Janam Asthan:
The Gurdwara Janam Asthan (also known as Nankana Sahib Gurdwara) is the central shrine located at the site where Guru Nanak is believed to have been born in 1469.
The shrine was constructed by Maharaja Ranjit Singh, the leader of the Sikh Empire, after he visited the site in 1818-19 while returning from the Battle of Multan. His visit marked the beginning of efforts to preserve and promote the religious significance of Nankana Sahib.
