* Anthropic's IPO prospectus highlights risks associated with its AI models, which it said could exhibit "self-preserving behaviors," including attempts to "resist shutdown," to "conceal or manipulate information" and behavior "resembling blackmail."

* Prompt LLMs using ASD-STE100 for clearer outputs.

ASD-STE100 is Simplified Technical English, a controlled language standard for aerospace maintenance manuals with rules like short sentences, one action per step, active voice, and strict consistent naming of objects to ensure global readability and safety.

Applying "80% ASD-STE100" style to LLM prompts reduces ambiguity by enforcing one name per concept and precise structure, making complex explanations more parsable than standard AI prose.

* Paper [^PDF] discussing multimodal wearable assistive system designed to help people who are blind or have low vision (pBLV), independently locate and retrieve products in physical stores. The system integrates object detection with vision-language models (VLMs) to enable three-phase product assistance: product search, product navigation, and product-targeting correction. The system leverages United States subset of the Open Food Facts (OFF) database to acquire target product images.

* Freebie Culture or Women’s Empowerment? - The ‘Vettri Payanam’ scheme in Tamil Nadu no-fare bus travel for women and transgender persons is an expansion of the five-year-old ‘Magalir Vidiyal Payanam’ program. With this upgrade, women can travel for free on ordinary, express, limited stop service (LSS), and deluxe buses in cities and towns, as well as on ordinary buses in rural areas and ghat sections beyond 40 km. The scheme will reach 84.32 lakh beneficiaries daily. A total of 12,695 buses from the Tamil Nadu's seven State Transport Corporations are part of the initiative, operating 1,68,500 single trips daily. Vettri Payanam is expected to cost the state government approximately ₹6,000 crore annually.

RTCs involved in Karnataka's Shakti scheme (since June 2023) spent ~₹20,956 crore (cumulatively till mid-2026; reimbursements lag). The scheme benefits ~1.9 crore women. Telangana's Mahalakshmi scheme (since Dec 2023) costs ₹3,000+ crore/year range (e.g., ₹3,866 crore reimbursed in 2024-25) for ~35–37 lakh daily women journeys.

While Ayurvedic license is governed under the Drugs & Cosmetics Act, 1940 (Ayurveda, Siddha, Unani section), allopathic license requires approval from CDSCO (Central Drugs Standard Control Organization) and involves clinical trials, pharmacovigilance, bioequivalence studies, and stricter GMP standards. The license has a much higher cost and longer timelines. Renewal and regulatory audits are more intensive.
