Gastrodia keyiensis-ghost flower

Why in News?
Scientists have discovered a new, rare leafless orchid species named Gastrodia keyiensis (popularly called the 'Ghost Flower') in the Keyi Panyor district of Arunachal Pradesh.
 

Discovery & Habitat
  • Location: Found at an elevation of around 1,000 metres in a remote gorge near the Keyi River in Keyi Panyor district, Arunachal Pradesh.
  • Etymology: The species name keyiensis directly honours the Keyi River where it was located.
  • Local Identity: In the local Nyishi dialect, it is called "Oram Opuh", which translates to "Ghost Flower".
  • Environment: It thrives in dark, humid ecosystems, growing in deep shade on decaying leaf litter within bamboo groves.
Unique Biological Features
  • No Leaves or Chlorophyll: Unlike typical plants, it completely lacks green leaves and chlorophyll, meaning it cannot perform photosynthesis.
  • Holomycotrophic Nature: It survives entirely through holomycotrophy—a symbiotic relationship where it relies on soil fungi and decaying organic matter for its nutrients.
  • Physical Appearance: The plant grows up to 35 cm in height and produces 1 to 3 flowers. The flowers are white to pale bluish with a distinctively thick, strongly curved yellow lip (labellum).
  • "Ghostly" Behaviour: The plant spends the vast majority of its life cycle entirely concealed beneath the forest floor, emerging only briefly during its short flowering period.
Conservation Status
  • Data Deficient (DD): Because it has only been documented in one location covering an estimated occupancy area of about four square kilometres, the International Union for Conservation of Nature (IUCN) criteria temporary places it under the Data Deficient category.
  • Orchid Paradise: The addition of this species further strengthens Arunachal Pradesh's reputation as the "Orchid Paradise of India", which boasts around 600 documented orchid species.

Neodymium-Iron-Boron (NdFeB) Magnets

Why in News?
The International Energy Agency (IEA) has highlighted high-performance Neodymium-Iron-Boron (NdFeB) magnets as strategically vital components for the global clean energy transition.
 

Composition & Chemistry
  • Chemical Structure: NdFeB magnets are rare-earth permanent magnets made from a specific alloy crystal structure formulated as Nd₂Fe₁₄B. 
  • Elemental Ratio: A standard industrial composition typically contains 29–32.5% Neodymium, 64–69% Iron, and 1.1–1.2% Boron by mass. 
  • Functional Roles:
    • Neodymium atoms serve as the source of powerful magnetic dipoles.
    • Iron atoms provide the overall volume and magnetic field strength.
    • Boron atoms form strong covalent bonds to stabilize the alignment of the crystal lattice. 
Key Technical & Magnetic Properties
  • Extreme Field Strength: They are the strongest commercially available permanent magnets in the world, capable of lifting hundreds of times their own weight. 
  • High-Performance Metrics: Standard grades exhibit an exceptional Maximum Energy Product (BHmax) exceeding 440 kJ/m³ (~55 MGOe), alongside a high remanence (up to 1.5 Tesla). 
  • High Coercivity: They show extraordinary resistance to demagnetisation when exposed to external opposing magnetic fields. 
Limitations & Vulnerabilities
  • Thermal Sensitivity: They possess a lower Curie temperature compared to other industrial magnets. Standard grades begin to degrade above 80°C to 150°C.
  • Thermal Upgrades: Advanced variations integrate heavy rare earths like Dysprosium (Dy) or Terbium (Tb) to safely withstand operational heat exceeding 150°C to 230°C.
  • Corrosion Susceptibility: Due to their high iron content, they rust quickly in humid conditions. They require protective surface coatings, most commonly a triple-layer plating of Nickel-Copper-Nickel (Ni-Cu-Ni). 
Industrial Applications
  • Electric Mobility: They provide the vital high-torque density required inside the traction motors of Electric Vehicles (EVs), where an average car utilizes 2 to 2.5 kg of these magnets.

Nevados de Chillán Volcano

Why in News?
Nevados de Chillán is in the news because the highly active volcanic complex erupted and sending massive plumes of ash, gases, and pyroclastic material up to 380 m (≈1,250 ft) above the crater, drifting southwards.
 

Key Information
  • Geographical Location: It is a massive composite stratovolcanic complex situated in the Southern Volcanic Zone of the Chilean Andes, specifically within the Ñuble Region of south-central Chile.
  • Three Overlapping Peaks: The complex consists of three main overlapping peaks that stretch along a north-northwest to south-southeast axis:
    • Cerro Blanco (Volcán Nevado): The highest peak in the northwest, standing at 3,212 metres (10,538 feet).
    • Volcán Viejo (Volcán Chillán): Located in the southeast, standing at 3,089 metres (10,135 feet). It was the primary active vent between the 17th and 19th centuries.
    • Volcán Nuevo: Positioned directly between the two, it formed as a lava dome complex between 1906 and 1945 and eventually grew taller than Volcán Viejo.
  • Tectonic Mechanism: The volcano sits on the volatile Pacific "Ring of Fire". Its eruptive activity is driven by subduction tectonics, where the westward movement of the South American plate overrides the Nazca plate.
  • Historical Eruptions: Documented eruptions date back to the 17th century, though geological mapping shows active volcanism spanning back hundreds of thousands of years. A major eruptive cycle began in January 2016 from the Nicanor crater and has experienced intermittent phases of dome growth and explosion.
  • Eruption Characteristics: Nevados de Chillán is primarily known for lava-dome growth, explosive ash plumes, block-and-ash pyroclastic flows, and lapilli emissions.
  • Socio-Economic Risks: It is ranked as one of the highest-risk volcanoes in Chile. This high-risk status is compounded by rapid commercial development on its southwestern flanks, which host extensive skiing resorts, hotels, and vacation properties that are highly vulnerable to lahars (volcanic mudflows) caused by melting snow.
 
 
 
Rebate of State and Central Taxes and Levies (RoSCTL) Scheme

Why in News?
The Rebate of State and Central Taxes and Levies (RoSCTL) Scheme is in the news because the Ministry of Textiles extended the scheme for the export of apparel, garments, and made-ups until 30 September 2026.
 

Overview and Objectives
  • Introduction: Launched in March 2019 by the Ministry of Textiles, India.
  • Core Purpose: It aims to reimburse all embedded State and Central taxes/levies on the export of manufactured apparel, garments, and textile made-ups.
  • The Principle of Zero-Rating: It operates on the internationally accepted trade principle that "taxes and duties should not be exported." This ensures Indian products remain globally competitive by eliminating hidden tax burdens.
  • Predecessor: It replaced the older Rebate of State Levies (RoSL) Scheme. Unlike RoSL, which only covered state taxes, RoSCTL covers both State and Central taxes.
What Taxes are Rebated?
The scheme refunds embedded indirect taxes that cannot be claimed or refunded through regular mechanisms like GST or standard Duty Drawbacks, including:
  • State Levies: VAT on fuel used in transportation, mandi tax, electricity duty, stamp duties, and embedded SGST paid on inputs like fertilizers/pesticides.
  • Central Levies: Central excise duty on fuel, embedded CGST paid on inputs, and Compensation Cess on coal used to produce electricity.
Key Features and Benefits
  • Duty Credit Scrips: Instead of cash, the rebate is provided as electronic, transferable duty credit scrips (e-scrips) via the Customs system.
  • Value Base: The value of these scrips is calculated based on the Free on Board (FOB) value of the exported goods.
  • Utilisation: Exporters can use these e-scrips to pay Basic Customs Duty on imports or freely sell/transfer them to other importers in the market for cash liquidity.
  • Validity: Once generated, an e-scrip is valid for one year, and its validity does not reset if it is transferred.
  • Rebate Rates: The maximum rebate rate goes up to 6.05% for apparel and up to 8.2% for textile made-ups (like bed linen, cushions, and carpets).
Eligibility & Implementation
  • Target Sectors: Exporters of apparel, garments, and made-up articles falling under Chapters 61, 62, and 63 of the ITC-HS code.
  • Primary Beneficiaries: It acts as a massive lifeline for MSME exporters, who make up a substantial share of India's textile export ecosystem.
  • Exclusions: Any entity listed on the Denied Entity List of the Directorate General of Foreign Trade (DGFT) is barred from benefits.
  • Implementing Agency: It is collectively overseen by the Ministry of Textiles and deployed by the Department of Revenue, Ministry of Finance.
