Ehlers-Danlos Syndrome: When Connective Tissue Loses Its Structural Strength

GS  III – Science & Technology | Health

Why in News?

Recent research has examined possible associations between Ehlers-Danlos Syndrome (EDS) and factors such as hormonal patterns and sleep-related conditions, drawing attention to the broader systemic effects of connective-tissue disorders.

What is Ehlers-Danlos Syndrome?

• Definition: EDS refers to a group of inherited disorders affecting connective tissue, which provides structural support to various parts of the body.
• Genetic Basis: Many EDS types involve abnormalities in collagen production, structure or processing.
• Affected Systems: Depending on the type, EDS can affect the skin, joints, blood vessels and internal organs.

Key Features

• Joint Hypermobility: Joints may move beyond their normal range because of reduced connective-tissue stability.
• Skin Changes: Skin may be unusually stretchy, soft or fragile.
• Easy Bruising: Fragile connective tissue can make blood vessels and surrounding tissues more susceptible to injury.
• Musculoskeletal Problems: Joint pain, instability and recurrent injuries can occur.
• Variable Severity: EDS is a group of disorders, so clinical features and severity differ considerably between subtypes.

Why is Collagen Important?

• Collagen is a major structural protein that provides strength and elasticity to connective tissues.
• Abnormal collagen synthesis or processing can therefore weaken tissues and affect their ability to withstand mechanical stress.

Pluto: The Dwarf Planet Debate

GS  III – Science & Technology | Space Science

Why in News?

• Nearly two decades after Pluto''s reclassification, renewed scientific discussion has emerged over whether the definition of a planet should be reconsidered.
• The debate primarily concerns whether the “clearing the neighbourhood” criterion should be retained as an essential requirement for planetary status.

Key Facts about Pluto

Why Was Pluto Reclassified?

In 2006, the International Astronomical Union (IAU) established three criteria for a celestial body to be considered a planet:

• Orbits the Sun.
• Has sufficient mass for its self-gravity to overcome rigid-body forces and achieve a nearly round shape.
• Has cleared the neighbourhood around its orbit.

Pluto satisfies the first two criteria but not the third. Its orbital region overlaps with numerous other objects in the Kuiper Belt, meaning it does not gravitationally dominate its orbital neighbourhood.

Why Does the Debate Continue?

• Planetary Definition: Some scientists argue that planetary classification should focus more on a body''s intrinsic physical characteristics and geological complexity rather than its ability to clear its orbital neighbourhood.
• Kuiper Belt Context: Pluto exists within a region containing numerous icy bodies, making its orbital environment fundamentally different from that of the eight recognised planets.
• Geological Complexity: New Horizons revealed Pluto to be a geologically active world with mountains, glaciers, diverse terrain and a complex atmosphere, strengthening scientific interest in how planetary categories should be defined.

• The Expert Appraisal Committee (EAC) of the Ministry of Environment, Forest and Climate Change has recommended environmental clearance for the 1,605 MW Subansiri Upper Hydroelectric Project in Arunachal Pradesh.  
• The recommendation involves diversion of about 2,733 hectares of forest land and potential felling of approximately 1.35 lakh trees, highlighting the ecological trade-offs associated with hydropower development in the Himalayan region.

 About the Suban siri River

Why is the Subansiri Basin Important?

• Hydropower Potential: The steep Himalayan gradient provides substantial potential for hydropower generation. The basin already hosts major projects, including the Subansiri Lower Hydroelectric Project.
• Strategic Geography: The upper basin lies in Arunachal Pradesh, a strategically important frontier region adjoining Tibet/China.
• Ecological Sensitivity: Himalayan river systems are highly sensitive to changes in river flow, sediment transport, forests and aquatic ecosystems.
• Disaster Risk: Hydropower development must account for flash floods, landslides, seismic risks and glacial hazards characteristic of the Himalayan environment.

UN Declaration on Sea Level Rise: Protecting States, Maritime Rights and Coastal Communities

GS  II – International Relations | GS  III – Environment

Why in News?

• On 24 September 2026, the UN General Assembly adopted a Political Declaration on addressing the existential threats posed by sea level rise at a high level plenary meeting.
• The declaration treats sea level rise as not merely an environmental concern but also a developmental, humanitarian, economic and legal challenge.

Key Highlights

• Vulnerability of SIDS: The declaration gives particular attention to Small Island Developing States (SIDS) and low lying coastal communities, which face risks from coastal flooding, erosion, saltwater intrusion and loss of livelihoods.
• Continuity of Statehood: It supports the principle that climate induced sea level rise and physical changes to territory should not automatically result in the disappearance of a state''s statehood, sovereignty or international legal personality. The issue has been a major concern for SIDS.
• Stability of Maritime Zones: The declaration recognises the importance of maintaining established maritime zones and associated rights despite physical changes caused by sea level rise.
• International Cooperation: It calls for stronger cooperation, adaptation and resilience measures, including support for vulnerable developing countries.
• Malé Declaration, 1989: The declaration builds on decades of advocacy by vulnerable island states, including the Malé Declaration on Global Warming and Sea Level Rise, adopted in the Maldives in November 1989.

Why Sea Level Rise Matters Beyond Environment

Significance

• From Environmental to Geopolitical Issue: Sealevel rise increasingly intersects with territorial integrity, sovereignty, maritime rights and international law.
• Climate Justice: Countries that have contributed relatively little to global emissions can face disproportionate exposure to climaterelated risks, strengthening demands for adaptation finance and international support.
• Human Rights and Development: Rising seas affect not only territory but also housing, health, food and water security, livelihoods and cultural heritage.
