UPSC Current Affairs 10 April 2026

• Fast-Tracking: The government proposes using the 2011 Census data instead of waiting for a new census, aiming to implement the quota by 2029.
• House Expansion: Reports suggest the Lok Sabha strength could increase from 543 to 816 seats, with roughly 273 seats reserved for women.
• Upcoming Debate: The amendment is scheduled for debate in Parliament during a special sitting from April 16–18, 2026. 

• 33% Reservation: Reserves one-third of seats in the Lok Sabha, State Legislative Assemblies, and the Delhi Legislative Assembly for women.
• Horizontal Reservation: One-third of seats already reserved for SCs and STs will be specifically allocated to women within those categories.
• Sunset Clause: The reservation is initially for a period of 15 years, though Parliament can extend it later.
• Rotation of Seats: Reserved seats will be rotated to different constituencies after each delimitation exercise. 

• Delimitation Requirement: Implementation was originally contingent upon a fresh Census and the subsequent redrawing of constituency boundaries (delimitation).
• Proposed 2026 Change: To avoid waiting until 2030+, the government now seeks to amend Article 334A to decouple the reservation from the next census.
• Constitutional Hurdles: Implementing these changes requires a Special Majority (2/3rds in both Houses) and ratification by 50% of the States. 

• Lok Sabha: Women currently hold about 13.6% to 15% of seats.
• State Assemblies: The average representation is significantly lower, at approximately 9%.
• Local Bodies: Over 1.4 million women already serve in Panchayats and Urban Local Bodies due to the 73rd and 74th Amendments (1992), which mandate 33% (or up to 50% in some states) reservation at the grassroots level. 

• For the Bill:
  • Addresses historical underrepresentation and patriarchal political structures.
  • Ensures a focus on gender-specific issues like maternal health, safety, and economic empowerment.
• Against/Concerns:
  • OBC Quota: The bill currently lacks a sub-quota for women from Other Backward Classes (OBC), a major point of contention for opposition parties.
  • Rajya Sabha: The reservation does not apply to the Upper House (Rajya Sabha) or State Legislative Councils.
  • Tokenism: Critics fear "Sarpanch-Pati" syndrome, where male relatives might wield power behind female representatives.

• Safety Initiative: These sleepers are being prioritized for girder bridges and points & crossings to reduce vibrations and improve passenger comfort.
• Load Bearing Milestone: The new sleepers approved are capable of withstanding loads up to 700 kg per square centimetre, outperforming traditional concrete in specialized environments.
• Modernization Package: Their rollout is being paired with Artificial Intelligence (AI) devices like Ground Penetration Radar for continuous track base assessment.

• Mixed Materials: Made from a combination of recycled plastics (like HDPE), crumb rubber, and glass fibre reinforcement.
• Eco-Friendly: Often referred to as "Green Sleepers," they help prevent deforestation by replacing wooden sleepers and utilize non-biodegradable waste.
• Recyclability: These sleepers are nearly 100% recyclable at the end of their service life. 

• High Durability: They have an estimated service life of 40–50 years, nearly double that of traditional wooden sleepers.
• Vibration Damping: Unlike rigid concrete, composites absorb shocks and noise, making them ideal for high-speed corridors and urban metro lines.
• Resistant to Decay: They are impervious to insect attacks (termites), moisture, UV radiation, and chemical corrosion.
• Weight Advantage: Lighter than concrete (about 1/3rd the weight), they are easier to transport and install, especially in difficult terrain. 

• Bridge Approaches: Used on girder bridges to manage dead load and provide better cushioning than heavy iron or concrete.
• Points & Crossings: Their flexibility allows for custom grooving and drilling, making them superior for complex track geometry.
• Track Circuiting: Because they are electrically non-conductive, they provide 100% insulation, which is critical for signal safety in track-circuited areas. 

• Upfront Cost: Initial manufacturing costs are higher (approx. ₹25,000 per sleeper vs. ₹7,000 for channel sleepers).
• Long-term Savings: Reduced maintenance needs and a longer lifecycle make them more cost-effective over their entire 50-year lifespan.

• Cricket Frog Inspiration: Just as these frogs respond to moisture and daylight, the sensor's activity level shifts with humidity and light intensity.
• Organic Nanofibres: The sensor is built using supramolecular nanofibres (organic materials) that act as "artificial neurons".
• Multimodal Response: It doesn't just "detect" humidity; it uses light to "enhance" its response, similar to how biological systems integrate multiple senses. 

• Memory Function: Unlike standard sensors, it can "remember" previous humidity levels for a short time (short-term memory), allowing it to adapt its future responses based on past data.
• Synaptic Weight Updating: It mimics synaptic plasticity, the process where brain connections strengthen or weaken through use.
• Dual Operation: It combines the sensor and the processor into one tiny component, eliminating the need to move data between separate chips. 

• Energy-Efficient AI: Reduces the massive power consumption of conventional AI chips by processing data "at the edge" rather than in massive data centers.
• Healthcare & Monitoring:
  • Respiration Trackers: Identifying breathing patterns (normal, snoring, or sleep apnea) through moisture changes in breath.
  • Wearable Health Devices: Long-lasting monitors for heart rate or skin perspiration.
• Environment & Industry:
  • Smart Agriculture: Managing greenhouse humidity with adaptive, low-power systems.
  • Industrial Monitoring: Tracking moisture in harsh environments like industrial exhausts.
• Touchless Interfaces: Using the moisture from a finger to control computers without physical contact. 

• The Discovery: Using high-speed photography, scientists found that when cornstarch mixtures are hit at extreme speeds, they behave like a liquid first before instantly toughening into a solid.
• Space Applications: This mathematical model is being explored for 3D printing on the moon and designing "soft robots" that can change their stiffness on command. 

• The Warning: Doctors have labelled industrial cornstarch as one of the most hazardous carbohydrates because it is processed to be absorbed faster than actual sugar, causing extreme blood sugar spikes. 

• Source: Derived from the endosperm (the starchy center) of corn kernels.
• Production: Created through wet milling, which separates the starch from the corn's protein, fiber, and oil.
• Nutritional Value: It is essentially pure carbohydrate; it contains zero fiber, protein, or vitamins. 

• Thickening Agent: Used for sauces, soups, and gravies; it becomes translucent when heated, unlike wheat flour.
• Anti-Caking: Added to powdered sugar and shredded cheese to prevent clumping by absorbing moisture.
• Crispy Texture: Often used as a coating for fried foods to achieve a light, crunchy exterior.
• Gluten-Free Alternative: A staple for individuals with Celiac disease, though less nutritious than whole-grain alternatives like oat flour. 

• Pharmaceuticals: Acts as a "disintegrant" to help tablets and capsules break apart in the stomach.
• Glycogen Management: Used as a slow-release glucose source for patients with Glycogen Storage Disease (GSD).
• Bioplastics: A primary raw material for making biodegradable plastics (PLA) and eco-friendly packaging.
• Hygiene: Historically used in baby powder and as a lubricant in surgical gloves (though the latter is now restricted due to inflammation risks). 

• High Glycemic Index: Causes rapid insulin spikes, which may contribute to Type 2 Diabetes and fatty liver.
• Inflammation: Excessive consumption of refined cornstarch is linked to joint inflammation and "belly fat."
• Pica Disorder: Compulsive cravings for raw cornstarch can be a sign of pica, often linked to iron deficiency or anemia. 

• Launched: Approved by the Union Cabinet in April 2023; operational phase started in late 2024.

• Budget 2026 Mandate: The Union Budget 2026 has made it compulsory for all Central Public Sector Enterprises (CPSEs) to settle their MSME purchases through TReDS.
• ₹1 Lakh Crore Milestone: In February 2026, M1xchange became the first TReDS platform to cross ₹1,00,000 crore in annual throughput in a single financial year, signalling massive industry adoption.
• Secondary Market Launch: The government has introduced a framework to allow TReDS receivables to be packaged as Asset-Backed Securities (ABS), creating a secondary market where these invoices can be traded like bonds. 

• Three-Way Marketplace: The platform brings together Sellers (MSMEs), Buyers (Corporates/Govt), and Financiers (Banks/NBFCs).
• The Auction Process:
  • Upload: MSME uploads an invoice for goods delivered.
  • Acceptance: The buyer accepts the invoice digitally, confirming the debt.
  • Bidding: Multiple financiers bid to discount the invoice (e.g., offering 98% of the value today).
  • Payment: MSME chooses the best bid and receives funds within 24–72 hours.
• Settlement: On the actual due date (e.g., 90 days later), the buyer pays the full amount directly to the financier. 

• Turnover Threshold: All companies with a turnover exceeding ₹250 crore are now required to register on the TReDS platform (reduced from the previous ₹500 crore limit).
• "Without Recourse": This is the most critical feature—if the buyer fails to pay the financier, the MSME is not liable to return the money. The risk lies entirely with the financier.
• No Collateral: Financing is based purely on the creditworthiness of the buyer, not the MSME's assets. 

• Liquidity: Converts "paper wealth" (invoices) into immediate working capital.
• Lower Costs: Competitive bidding often results in interest rates much lower than traditional bank loans.
• Transparency: Every step is tracked on a secure digital ledger, reducing the risk of fraud or duplicate financing.
