Current Affairs – December 15-16, 2024

{GS1 – Geo – Solar System} Daylight Saving Time in US

• Context (TH): The US President wants to end daylight saving time in the U.S.

• Daylight saving time (DST) or summer time is the practice of advancing clocks by one hour during summer months in the US. In DST, evening time is increased by sacrificing the morning hours.
• Typically, users in regions with summer time (some countries in the extreme north and south) adjust clocks forward one hour close to the start of spring and backwards in the autumn to standard time.
• DST aims to improve energy efficiency by reducing the need for artificial lighting, making it relevant to climate change and energy overconsumption. It is considered an environmentally sustainable concept.

History and Adoption of Daylight Saving Time (DST)

• The practice was first suggested in a whimsical essay by Benjamin Franklin in 1784. Australia, Great Britain, Germany, and the US adopted summer Daylight Saving Time during World War I to conserve fuel by reducing the need for artificial lighting.
• Current Practice: Today, DST is practised in around 70 countries, including the European Union.
• India’s case: India does not observe DST, primarily because countries near the Equator do not experience variations in daylight hours between seasons.

Problems with Daylight Saving Time

• Operational and Communication Issues: It can cause problems for businesses, travel, and communication as coordinating activities across regions with different time observances becomes more complex.
• Health Consequences: These disruptions can lead to negative health effects, including increased risk of sleep disorders, reduced cognitive function, and higher incidence of heart attacks and strokes.
• Sleep Disturbance: The time change can disrupt people’s sleep patterns and circadian rhythms.
• Possible Surge in Energy Demand: In certain regions, time change can actually lead to increased energy consumption due to greater reliance on heating & cooling systems during extended daylight hours.
• Time Zone Disparities: Not adopted universally confusion and inconsistencies across different zones.

{GS2 – Polity – IC – Parliament} Presidential Impeachment in South Korea **

• Context (TH | TH | TH): South Korea’s lawmakers impeached President Yoon Suk Yeol after his failed attempt to impose martial law in December 2024, while South Africa’s opposition seeks to revive impeachment proceedings against President Cyril Ramaphosa over the “Farmgate” scandal.

Need for Impeachment Procedures and Advantages

• Ensures Accountability: Impeachment holds public officials accountable for misconduct, prevents abuse of Presidential powers, and protects democracy by enforcing constitutional limits.
• Deterrent for Misconduct: Impeachment acts as a deterrent against future misconduct by public officials, promoting integrity within government.
• Public Participation: Involves the public in decision-making processes through protests, rallies, and electoral influence, as seen in South Korea.

Comparison of Impeachment Procedures

Also refer to Comparative Procedures of Impeachment of Presidents of USA and India

Negative Impact of Impeachment Proceedings

• Political Instability: In both South Korea and South Africa, impeachment proceedings often deepen political polarisation, as witnessed in South Korea’s divided rallies, impacting national unity.
• Legal Hurdles: Both countries face significant legal complexities, such as lengthy constitutional court proceedings and conflicting political interests that delay or prevent action.
• Weakening of Governance: Suspension of the president can lead to a power vacuum, hampering effective governance and policymaking.
• Erodes Public Trust: Allegations of misconduct, such as in South Africa’s “Farmgate” scandal, risk eroding public trust in governmental institutions if not properly addressed.

Way Forward

• Strengthen Legal Frameworks: Countries should ensure transparent and consistent legal procedures for impeachment to avoid political manipulation.
• Ensure Independent Oversight: Bodies like South Africa’s Constitutional Court must ensure impartial investigation of allegations to prevent political bias.

{GS2 – Social Sector – Health} Addressing Snakebite Mortality in India

• Context (IE | TH | LL): SC sought replies from the Centre & states on a plea addressing the urgent need for anti-venom availability & snakebite treatment infrastructure to tackle India’s high mortality rate.

Need for Action

• Global Leader in Snakebite Deaths: India records approximately 58,000 deaths annually, contributing to nearly 50% of global snakebite fatalities.
• Critical Public Health Issue: High mortality is particularly concentrated in rural areas due to delayed treatment and inadequate resources.
• Snakebite ‘Hotspots’: UP, West Bengal, Odisha & AP face disproportionately high incidences.

Challenges in Snakebite Management

• Scarcity of Anti-Venom: Limited production, inconsistent supply and inadequate stockpiles in primary and secondary health centres delay effective treatment.
• Lack of Awareness and Training: Reliance on harmful traditional practices and untrained healthcare workers in rural areas hampers WHO-recommended snakebite management.
• Infrastructure Deficits: Poor anti-venom distribution and the absence of specialised care units leave rural regions underserved.
• Policy Gaps: No dedicated budget or national-level program exists for snakebite treatment.
• Inadequate Schemes: Ayushman Bharat and NHM (National Health Mission) fail to comprehensively address snakebite-related issues.

Measures for Enhancing Snakebite Prevention and Management

• Nationwide Awareness Campaigns: Conduct large-scale campaigns focusing on prevention and first aid for snakebites, targeting high-risk areas. Incorporate WHO’s five-pillar framework on snakebite management into medical curricula.
• Training Community Health Workers: Equip ASHAs and health workers with knowledge to educate communities on snakebite treatment & emergency care.
• Integrate Snakebite Care in Healthcare System: Integrate services under Ayushman Bharat and NHM with mobile snakebite care units.
• Real-Time Supply Chain Management: Ensure anti-venom stocks with cold-chain and maintain systems for efficient anti-venom distribution to address supply-demand gaps effectively.
• Region-Specific Anti-Venom Production: Collaborate with pharmaceutical companies to scale up the production of region-specific anti-venoms and implement real-time supply tracking.
• Strengthen Monitoring and Oversight: Create a central nodal agency for program management and implement regular audits with feedback mechanisms.
• Policy-Level Interventions: Introduce a National Snakebite Prevention and Management Mission under NHM and allocate dedicated funds for snakebite initiatives.
• Community awareness: Implement community awareness programs and standardised anti-venom distribution to reduce snakebite mortality rates effectively, like the Sri Lanka model.
• Use Technology for Resource Allocation: Employ GIS to map high-risk zones and optimise resource distribution effectively.
• Focus on Research: Invest in advanced, low-cost anti-venoms tailored to India’s diverse snake species.

{GS3 – S&T – BioTech} Mirror Life Bacteria *

• Context (TH | FP): Scientists are increasingly concerned about the potential risks posed by ‘mirror life bacteria’, synthetic microbes created from mirror images of naturally occurring molecules.

• Life on Earth is built from biomolecules like DNA, proteins, and carbohydrates, which possess a unique property called chirality or structural asymmetry.

How Mirror Bacteria Created?

• Mirror bacteria are synthesised in labs using molecules with reversed chirality.
• The concept is derived from existing pharmaceutical applications, where mirror-image molecules prolong drug activity by resisting natural enzymatic breakdown.

Potential Benefits

• Industrial Use: Mirror bacteria could be employed in industrial processes such as decomposition, fermentation, and speeding up chemical reactions due to their resilience.
• Therapeutic Uses: It can be developed into therapies for treating chronic and hard-to-treat diseases.
• Bioproduction: It can produce chemicals through biological processes involving synthetic bacteria.

Risks and Concerns

• Evasion of Natural Predators: Mirror bacteria could evade natural immune responses and predators, including viruses and microbes that usually keep bacterial populations in check.
• Human and Animal Health: These bacteria could cause lethal infections that spread unchecked in humans, animals, and plants.
• Ecological Impact: Their resilience could lead to uncontrolled spread across ecosystems, potentially contaminating various environments.

{GS3 – S&T – Space} Firefly Sparkle Galaxy

• Context (IE): The James Webb Space Telescope found a rare Firefly Sparkle galaxy. It is one of the earliest low-mass galaxies ever discovered and offers invaluable insights into early galaxy formation.

• Named so because its star clusters shine brightly in images captured by the JWST.
• JWST used gravitational lensing to magnify the galaxy’s light, allowing for detailed observations.
• Mass: This galaxy has a mass equivalent to 10 million suns, categorising it as a relatively low mass.
• Size: Its visible portion spans just 1,000 light-years, contrasting the Milky Way’s 100,000 light-years.
• Star Clusters: It contains 10 distinct star clusters, each representing different stages of star formation.
• Companions: Accompanied by 2 smaller galaxies named Firefly-Best Friend & Firefly-New Best Friend.
• Shape: Its elongated raindrop shape indicates that it is still in the process of formation.

Gravitational Lensing

• Gravitational lensing happens when a huge celestial body, like a galaxy cluster, bends the path of light around it. This effect makes the light curve as if passing through a lens.
• The object causing the light to bend is called a gravitational lens. This bending effect magnifies the light, allowing us to see distant objects that would otherwise be too faint and far away.
• In 1915, Albert Einstein first predicted gravitational lensing. According to his general theory of relativity, time and space are combined into a single entity called spacetime. Massive objects cause spacetime to curve, and gravity is this curvature.
• Light Bending: When light from a distant object passes by a gravitational lens, its path curves, creating a distorted image. This image might look like a ring or halo around the lensing object.

About idiopathic pulmonary fibrosis (IPF) Disease

• It is a chronic and progressive lung disease characterised by the thickening and stiffening lung tissue, leading to irreversible scarring (fibrosis).
• The term “idiopathic” means that the cause of the condition is unknown.
• Symptoms: Common symptoms include shortness of breath (dyspnea), a persistent dry cough, fatigue, and weight loss. Over time, oxygen levels in the blood may drop, leading to complications such as pulmonary hypertension and respiratory failure.
• Risk Factors: Ageing, particularly in individuals over 50 years old. Smoking, a family history of the condition, and prolonged exposure to dust or certain chemicals can also increase the risk.
• Treatment: While there is no cure for IPF, treatments can help manage symptoms and slow disease progression. These may include pulmonary rehabilitation, supplemental oxygen, and medications like pirfenidone or nintedanib. In severe cases, lung transplantation may be considered.
