South Coast Railway (SCoR) = India’s 18th railway zone, HQ Visakhapatnam, formed by carving high freight-rich coastal divisions from ECoR and SCR.

Key Divisions:
• Visakhapatnam, Vijayawada, Guntur, Guntakal

Why important:
• Covers coastal + mineral-rich belt —> high freight potential
• Linked to major ports (Vizag)

Controversy:
• Odisha opposes —> loss of freight-rich areas from ECoR
• ECoR earns >90% revenue from freight --> reason for Odisha’s opposition
• Issue linked to inter-state resource and revenue sharing

Semaglutide (GLP-1 drugs):
• Semaglutide —> a GLP-1 receptor agonist used for Type-2 Diabetes + obesity (weight loss).
• Works by —> ↑ insulin secretion, ↓ glucagon, slows gastric emptying —> appetite suppression.

Drug Class & Examples:
• GLP-1 analogues: Semaglutide, Liraglutide, Tirzepatide (dual GIP + GLP-1)

Prelims Traps:
• Not for Type-1 diabetes
• Not a fat burner —> acts hormonally

Dengue:-
• Caused by Dengue virus (Flavivirus); transmitted by Aedes aegypti mosquito (day-biter)
• Four serotypes: DENV-1, 2, 3, 4 —> infection by one ≠ immunity to others
• Antibody-Dependent Enhancement (ADE): prior infection can worsen severity on reinfection
• Severe dengue linked to immune overreaction + vascular leakage
• Urban disease: thrives in clean stagnant water, rapid urbanisation
• Climate change —> expands mosquito habitat (temperature + rainfall sensitive)

Newspaper takeaways:
• COMBAT project: Indo-EU initiative —> studies why dengue turns severe

• Uses AI + single-cell sequencing + biomarkers —> decode host response

• Organ-on-chip: lab simulation of human organs (no human testing)

• Qdenga (TAK-003): approved in India (18–60 yrs), ~84% efficacy, no pre-screening

• ICMR ‘DengiAll’: Phase-III, single-dose recombinant vaccine

• Key hurdle: ADE + 4 serotypes —> vaccine complexity

Orbital AI Satellite =(Pathfinder)
• India’s 1st orbital data-centre satellite —> Pixxel + Sarvam AI partnership
• ~200 kg | Launch: 2026
• Carries data-centre grade GPUs —> AI training + inference in space
• Runs LLMs in orbit —> reduces dependence on ground cloud
• Concept: “compute in space where data is generated”—>(edge computing in space)

Orbital Data Centres — Core Idea
• Satellites acting as cloud/data centres in orbit
• Powered by continuous solar energy
• Enable real-time processing (edge computing in space)

Why Needed
• AI —> huge energy demand (data centres crisis)
• Space —> unlimited solar + natural cooling
• Reduces latency (no need to send data to Earth)
• Avoids land, water, regulation constraints
