Ancient Stepped Reservoir Unearthed at Elephanta Island

The Archaeological Survey of India has unearthed a 1,500-year-old stepped reservoir at Elephanta Island near Mumbai during excavations.

Key Highlights

• The reservoir is:
  • About 14.7 metres long
  • T-shaped structure
  • Excavated up to 5 metres depth
  • Contains around 20 stone steps
• The structure was carefully designed for water storage, indicating advanced ancient engineering.

Archaeological Findings

• Excavations revealed:
  • Brick structures (possibly dyeing vats)
  • Terracotta figurines
  • Glass and stone bangles
  • Beads made of carnelian and quartz
• Around 3,000 amphorae sherds of Mediterranean origin were found, indicating ancient trade links.

Historical Significance

• Some coins belong to Krishnaraja of the Kalachuri dynasty (6th century CE).
• About 60 coins (copper, silver, lead) were discovered.

Scientists Developed Frog-Inspired Neuromorphic Sensor

Scientists from Jawaharlal Nehru Centre for Advanced Scientific Research have developed a humidity-responsive neuromorphic sensor inspired by frogs, marking a breakthrough in smart electronics. This is the first device where humidity is used as a primary stimulus to mimic synaptic (brain-like) behaviour.

Key Highlights

• The sensor mimics brain-like functioning, integrating sensing, processing and memory.
• All in a single device, unlike conventional electronics

Technology Insight

• Detects humidity changes and “remembers” previous signals
• Inspired by cricket frogs, whose activity depends on moisture and light.
• The sensor uses Supramolecular nanofibers.

Indian Space Situational Assessment Report (ISSAR) 2025

The Indian Space Situational Assessment Report (ISSAR) 2025 highlighted significant growth in global space activities and India’s space assets.

Global Space Activity (2025)

• The year 2025 witnessed 315 successful space launches worldwide.
• A total of 4,651 objects were placed in orbit, marking the highest-ever deployment of payloads.
• Around 1,911 objects re-entered the atmosphere, resulting in a net annual growth of 74.5% in space objects.

India’s Space Assets

• India launched 8 satellites and 4 rocket bodies placed in orbit.

Satellite Status

• Total Indian satellites in orbit – 86
  • 27 operational
  • 23 defunct (inactive but still in orbit)
  • 36 decayed (fallen back to Earth)

Additional Highlights

• India carried out 563 orbital manoeuvres in Low Earth Orbit (LEO) and 519 manoeuvres in Geostationary Orbit (GEO).
• IRNSS-1D satellite was decommissioned above geosynchronous orbit.

World Homoeopathy Day – 10 April

World Homoeopathy Day was observed on April 10, 2026, commemorating the birth anniversary of Dr. Samuel Hahnemann, the founder of homoeopathy.

Key Highlights

• The World Homoeopathy Day theme 2026 was “Homoeopathy for Sustainable Health”
• Homoeopathy is based on the principle: “Like cures like”
• It uses highly diluted natural substances to stimulate the body’s self-healing mechanism.

Homoeopathy in India

• Homoeopathy was introduced in India around 1810.
• India has one of the largest homoeopathy systems in the world with around 3.45 lakh registered doctors, over 8500 dispensaries, 277 educational institutions and 34 research centres.
