🔆 Significance and Applications of the Discovery

📍 1. Cellular Development
✅ miRNAs are key for the self-renewal and differentiation of stem cells.
✅ Crucial for tissue and organ formation during embryonic development.

📍 2. Immune System Regulation
✅ Controls both innate and adaptive immune responses.
✅ Helps regulate immune-related proteins production.

📍 3. Cancer and Oncogenesis
✅ Abnormal miRNA activity linked to uncontrolled cell growth and tumor formation.
✅ Involved in mutations causing:
• Congenital hearing loss
• Skeletal deformities
• Eye-related genetic diseases

📍 4. Diagnostics and Therapeutics
✅ miRNAs serve as biomarkers for cancer detection and other diseases.
✅ Potential targets for drug development and personalized medicine.

🔆 Advanced Driver Assistance System (ADAS)

📍 What is ADAS?
ADAS are digital systems in vehicles that assist drivers with tasks like navigation and parking.

📍 How does it work?
✅ Sensors, cameras, and radar are used to monitor the vehicle’s environment, enabling features like:
• Automatic emergency braking
• Forward collision warning
• Blind spot collision warning
• Lane-keeping assist
• Adaptive cruise control

📍 Objective:
✅ The main goal is to reduce the frequency and impact of unavoidable vehicle accidents, thus preventing fatalities and injuries.

🔆 Trade Policy For Viksit Bharat

📍 About Trade Policy
✅ Defines the nation’s framework of laws, regulations, agreements, and practices governing international trade.
✅ Aims to strengthen the domestic economy through structured trade practices.
✅ Growth Target: Exports to rise from $775 billion (2023-24) to $2 trillion by 2030.
✅ This growth is three times faster than the global export pace.

📍 Challenges to India’s Trade Policy
✅ Bilateral Investment Treaties (BITs): Domestic legal barriers hinder trade agreements.
✅ Low Regional Integration: Trade with SAARC & BIMSTEC nations remains under 6%.
✅ Weak Global Supply Chain Integration: Limits India’s role in global trade dominance.
✅ Service Export Constraints: Restrictions under GATS limit flexibility.
✅ EU’s CBAM Impact: Could hurt steel and cement exports.

📍 Vision: Viksit Bharat 2047 aims to achieve economic growth, sustainability, social progress, and good governance.

The Extent of Human Land Use

The Neelakurinji was listed as vulnerable on the IUCN Red List of Threatened Species in 2024

🔆 Mitochondrial Donation Treatment (MDT)
An advanced reproductive technique using healthy mitochondrial DNA from a donor to prevent transmission of mitochondrial diseases.

📍Key Benefits
✅ Prevents inherited diseases – avoids passing mitochondrial disorders.
✅ Genetic continuity – retains parents’ nuclear DNA.
✅ Supports same-sex couples – enables both partners to contribute genetically.
✅ Reduces long-term healthcare costs.
✅ Drives medical innovation – encourages research and new tech.
✅ India status – currently not permitted.

📍Key Concerns
✅ Health risks to donors – egg retrieval is invasive.
✅ Ethical dilemmas – child’s identity, psychological impacts.
✅ Access inequality – risk of exploitation and elite monopoly.
✅ Data gap – limited evidence on safety.
✅ High cost – unaffordable for many.

📍Way Forward
✅ Need for regulatory body, ethical safeguards, and clinical trials before adoption.

🔆 Implications of Ageing

📍 Key Challenges
✅ Shrinking workforce, slowing growth, and rising pension burden
✅ Increased geriatric care demand and healthcare system stress
✅ Breakdown of joint families, elder loneliness, and social insecurity
✅ Need for reform in retirement age, pension systems, and re-skilling

📍 Government Initiatives
✅ National Policy for Older Persons (1999): Ensures rights-based welfare
✅ MWPSC Act (2007): Mandates family support for elders
✅ IPOP: Supports NGO-led elderly services
✅ Rashtriya Vayoshri Yojana: Assistive devices for BPL seniors
✅ IGNOAPS: Monthly pensions for 60+ BPL citizens
✅ Senior Citizens’ Welfare Fund: Uses unclaimed deposits for elder care
