1. BSF deployment moved to zero line along Bangladesh border in Murshidabad
Sub : Geo
Sec :Indian Geo
Context:
- The Border Security Force (BSF) has repositioned its personnel along the zero line of the India-Bangladesh border in West Bengal’s Murshidabad district, particularly in the char lands along the Padma River.
Current Deployment:
- BSF has deployed forces directly at the zero line along the border.
- Deployment spans from Farakka to Kakmarichar in Murshidabad.
- Three BSF battalions from the South Bengal Frontier are responsible for the deployment: Battalion 73, Battalion 146, Battalion 149.
Benefits of the Move:
- For Farmers:
- Farmers can now access their lands without needing prior permission from the BSF.
- Reduces hardships for farmers working on chars, which lack basic amenities like power and water.
- Border Security:
- Improves protection of the border.
- Eases the process for fencing and surveying the international border.
Background on Char Lands:
- The riverine areas (island) of the river Brahmaputra, locally known as “Char/ Chapori”.
- Chars are temporary land formations of sand and silt created by rivers, which appear and disappear based on river flow.
- These areas are crucial for farming but pose logistical and security challenges due to their dynamic nature.
- The chars follow a peculiar pattern of migration.
- They are subjected to erosion on their upstream and deposition on the downstream, due to which they migrate downstream.
- This affects the geometry and location of the chars during floods almost every year.
- Issues with Char area:
- The physical, sociological and institutional constraints on development of Char Areas are many and complex.
- Such as virtual absence of all weather communication with the main banks, reliable means of intra and inter char mobility, inadequate growth of transport and basic infrastructure like surface roads, health and drinking water, delivery systems for farm inputs, marketing, agro-services electricity and education.
- The problems in the Char Areas are unique in nature, due to constant threat from flood and erosion during the rainy season.
- The land mass is segregated and cut off from each other, making it very difficult for taking any major scheme for road communication, irrigation, Power supply or setting of educational institutions.
India- Bangladesh Border:
- The Bangladesh–India border, known locally as the Radcliffe line (IB), is an international border running between the republics of Bangladesh and India that demarcates the six divisions of Bangladesh and the Indian states.
- Bangladesh and India share a 4,096-kilometre-long (2,545 mi) international border, the fifth-longest land border in the world, including 262 km (163 mi) in Assam, 856 km (532 mi) in Tripura, 318 km (198 mi) in Mizoram, 443 km (275 mi) in Meghalaya and 2,217 km (1,378 mi) in West Bengal.
- The Bangladeshi divisions of Mymensingh, Khulna, Rajshahi, Rangpur, Sylhet, and Chittagong are situated along the border.
- West Bengal shares a 2,216-km border with Bangladesh, guarded by three BSF frontiers.
- Key Border Crossings:
- Prominent land ports include Petrapole-Benapole, which handles significant trade and passenger traffic.
- Other crossings: Akhaura (Tripura), Hili (West Bengal), and Dawki (Meghalaya).

Sec: Defence
Why in News
- India’s indigenous nuclear attack submarine (SSN) program has gained attention following approvals for its design and construction phases. The timeline indicates the design phase will take 4-5 years, with the first submarine expected to be ready by 2036-37. This milestone follows India’s experience with ballistic nuclear missile submarines (SSBNs) and recent advancements in submarine technology.
About Nuclear Submarines:
- SSNs have infinite capacity to stay dived. As they are not propelled by batteries, they need not emerge for charging by a diesel engine.
- Propelled by a nuclear-powered engine, these submarines only need to come to the surface for replenishing supplies for the crew.
- SSNs are also able to move faster underwater than conventional submarines. All this allows a navy to deploy them at farther distances, and quicker. They are like the fighter jets of the underwater world.
- India is among six nations that have SSNs, alongside the US, the UK, Russia, France and China.
- India got its first SSN in 1987 from the Soviet Navy, which it rechristened INS Chakra, which was decommissioned in 1991.
- In 2012, India got another Russian SSN on a ten-year lease, called INS Chakra 2, which has since been returned to Russia.
- The government has also decided that of the 12 submarines to be built indigenously after the P75 and P75i projects, six would be SSNs instead of SSK.
- Types of nuclear submarines:
- Ship Submersible Nuclear (SSN): one that carries conventional weapons.
- Guided Missile Submarines (SSGN): capable of carrying guided missiles with conventional warheads.
- Ship Submersible Ballistic Nuclear (SSBN): can carry ballistic missiles that may be nuclear armed.
About INS Aridhman (S4*):
- India’s fourth SSBN, the S4*, was launched into water at the SBC in Visakhapatnam.
- It has significant indigenous content, showcasing the involvement of Indian industry in its construction.
- It has a submerged displacement of around 7,000 tons, which is larger than its predecessor, INS Arihant, and allows for the inclusion of advanced systems.
- The submarine will carry the K-4 submarine-launched ballistic missile (SLBM) with a range of 3,500 km, crucial for India’s undersea nuclear deterrence.
- The S4* forms a key part of India’s nuclear triad, enabling second-strike capability from underwater, significantly boosting India’s strategic defence posture.
- It is one of the latest in a line of advanced SSBNs under construction, with plans to eventually integrate the K-5 SLBM, extending the strike range to 5,000 km
About INS Arihant (S2):
- It has a displacement of 6,000 tonnesand is powered by an 83 MW pressurised light-water reactor with enriched uranium.
- Retains the same reactor and dimensions, but has several technological upgrades.
- The advanced technology project began in the 1980sand its first product, the Arihant vessel, was launched in 2009 by then-Prime Minister Dr. Manmohan Singh, and eventually commissioned in 2016.
- The third of these submarines, which is at an advanced stage of construction, is set to be larger and more capable than the current two submarines in the same class.
About INS Arighaat (S3):
- INS Arighaat is a 6,000-tonne Arihant-class ballistic missile submarine.
- Arighaat will be armed with indigenously built K-15 missiles, with a range of more than700km.
- It can reach a speed of 12–15 knots (22–28 km/h) on the surface and up to 24 knots (44 km/h) when submerged.
- It is powered by 83 MW pressurised light-water nuclear reactors, which allow it to remain submerged and undetected for much longer than conventional diesel-electric submarines.
- Compared to Arihant, the indigenisation content has doubled in Arighaat (from 30% to 60%)
- INS Arighaat will enhance the Navy’s nuclear strike capability and will serve as a vital component of India’s nuclear triad.
- Arighaat adds to India’s sea-based nuclear deterrent, which is the most credible and survivable leg of the nuclear triad.
4. Advancing Malaria Prevention: Genetically Modified Parasites as a Next-Generation Vaccine
Sub : Sci
Sec: Biotech
Why in News
- Recent advancements in malaria research have highlighted the use of genetically modified parasites as a novel approach to priming the immune system against malaria. A groundbreaking study demonstrated the efficacy of late-arresting genetically modified parasites in providing enhanced protection compared to conventional methods like radiation-attenuated sporozoites.
Background:
- Use of genetically modified mosquitoes includes:
- Release of radiation-sterilized males to prevent egg hatching.
- Slowing parasite growth in mosquito guts to prevent transmission.
- Genetically engineering mosquitoes to spread resistance to malaria-causing parasites.
Genetic Modification of Parasites:
- Parasites are genetically modified to not cause disease.
- These modified parasites prime the immune system during their liver-stage life cycle before entering the
- Priming the immune system shields individuals when subsequently bitten by infected mosquitoes.
Aspect | Radiation-Attenuated Sporozoites | Genetically Modified Parasites |
Method of Action | Sporozoites are weakened using radiation, preventing them from causing disease. | Parasites are genetically modified to arrest their growth in the liver. |
Stage of Arrest | Parasite life cycle is disrupted immediately upon entering the liver. | Parasites are arrested on day six of the liver stage (late-arresting). |
Immune Priming | Shorter exposure period limits immune priming. | Longer exposure period allows more effective immune priming. |
Efficacy | Protection levels vary (50–90%) depending on dosage. | Late-arresting parasites show ~89% protection in trials. |
Dose Requirement | Requires approximately 1,000 mosquito bites for sufficient exposure. | Requires only 50 mosquito bites per immunization session. |
Cellular Immunity | Limited role in inducing specific T-cell responses. | Late-stage antigens induce strong P. falciparum-specific T-cell responses. |
Challenges | Logistical difficulty in administering large doses of sporozoites. | Safety and long-term durability of immunity need further research. |
About Malaria:
- A mosquito-borne disease caused by Plasmodium parasites, primarily transmitted by female Anopheles mosquitoes.
- Five species infect humans: P. falciparum, P. vivax, P. malariae, P. ovale, and P. knowlesi.
- Symptoms: Fever, chills, headache, muscle pain, and severe cases can lead to complications like cerebral malaria and death.
- Endemic in tropical and subtropical regions, with Africa bearing the highest burden.
About Plasmodium falciparum:
- The most virulent malaria-causing parasite, responsible for most malaria-related deaths globally.
- Capable of rapid multiplication in the bloodstream, leading to severe anaemia and cerebral malaria.
- Transmission: Sporozoites from mosquito saliva infect the human liver, then multiply and invade red blood cells.
About T Cells:
- A type of white blood cell critical in adaptive immunity, identifying and killing infected cells or activating other immune responses.
- Types: Includes helper T cells (CD4+) and cytotoxic T cells (CD8+).
- T cells respond to malaria antigens during the liver and blood stages, contributing to immune defence.
About Gamma Delta T Cells: A subset of T cells involved in recognizing and responding to non-protein antigens.
- They play a role in immunity against liver-stage malaria parasites, particularly in experimental late-arresting parasite trials.
About Sporozoites:
- The infectious stage of Plasmodium parasites transmitted by mosquito bites.
- Enter the bloodstream and travel to the liver, where they mature into merozoites.
