Recent observations by the 3I/ATLAS using the James Webb Space Telescope suggest that it may have formed 10–12 billion years ago, making it potentially older than the Sun and one of the oldest objects ever studied in the Solar System. Scientists have also detected methane and unusual chemical signatures in the comet.

Population Dynamics, Ageing, and Social Security
Introduction
India’s TFR has fallen to 1.9, below the replacement level, signalling a shift to low fertility. However, uneven fertility patterns and rapid ageing—projected to reach 347 million elderly by 2050—pose major challenges. Strengthening pensions, healthcare, and social security is essential to sustain this demographic transition.

Conclusion
India’s shift to low fertility brings the challenge of rapid ageing before achieving full economic and social development. With the elderly population set to more than double by 2050, India must strengthen pensions, healthcare, and social security while creating opportunities for its young workforce. A sustainable low-fertility future will depend on timely institutional and welfare reforms.

Constitutional Values, Democratic Institutions, and Media Freedom
Introduction
Fifty years after the 1975 Emergency, concerns persist about democratic backsliding through subtler means such as media self-censorship, pressure on dissent, weakening institutional autonomy, and expansive use of national security narratives. While today’s context differs from the Emergency, the episode remains a reminder of the need to safeguard democratic freedoms and accountability.
