1. Mudumal Megalithic Menhirs

Mudumal Megalithic Menhirs: The menhirs in Telangana’s Narayanpet district will soon be the second UNESCO World Heritage Site in the state.

• It was one of six Indian sites added to the tentative list by the World Heritage Centre in 2025.
• About Menhirs: A standing or upright stone, usually tapered at the top, man-made, sculpted, and placed by humans.
• The largest surviving menhir, the Grand Menhir Brisé in Brittany, France, once stood at 20.6 m tall.

• Etymology: Derived from Brittonic words — “maen” meaning “stone” and “hîr” meaning “long”. Entered the archaeological lexicon in the late 18th century, first used by French military officer and Celticist antiquarian Théophile Corret de la Tour d’Auvergne.
• European menhirs: Associated with the Beaker culture (Late Neolithic and Early Bronze Age), roughly 4,800 to 3,800 BP; oldest dated to 7,000 BP.
• Mudumal menhirs: Dated to roughly 3,500 to 4,000 BP — oldest known menhirs in India.

o Found either alone or as part of a larger complex of megaliths. Likely served ceremonial functions — markers of graves or for astronomical purposes.

• Astronomical Significance: Described as a “megalithic astronomical observatory” by the UNESCO dossier.

o Some menhirs align with the rising and setting sun during the summer and winter solstices, suggesting use as an ancient observatory.

• Cultural Significance: Closely associated with local legend — one menhir is worshipped as Goddess Yellamma.
• UNESCO Recognition: Reflects the ingenuity of early humans in sculpting and transporting tonnes-heavy stones with precision.

o Provides insight into cultural beliefs and astronomical knowledge of societies with no written records.

2. Hyperloop Technology

Hyperloop Technology: Recently, the Union Minister informed that the electronics component technology for the Hyperloop project will be developed at the Integral Coach Factory (ICF), Chennai.

• The 410-meter-long Hyperloop test tube at IIT Chennai is the longest Hyperloop test facility in Asia.
• About Hyperloop Technology: It is a high-speed transportation system where pods travel through low-pressure tubes at high speeds, popularised by Elon Musk in 2012.

o Working: Operates in vacuum-sealed tubes, reducing friction for faster travel and energy efficiency.

o Pods speed: Up to 1,100 kmph; operational cruising speed around 360 kmph.

• Key Components:

o Low-Pressure Tubes: Minimise air resistance.

o Magnetic Levitation (Maglev): Pods "float" on magnets, eliminating friction.

o Linear Electric Motors: Propel the pod smoothly and efficiently.

• Significance: Delivers high speed, efficiency, and zero direct emissions, making it a green transit solution.

o Addresses growing demands for efficient and sustainable transportation.

• India’s Hyperloop Project: Joint initiative of Indian Railways, IIT-Madras’ Avishkar Hyperloop team, and TuTr (incubated startup).
• About Magnetism: It is related to magnetic fields formed by moving electric charges. It occurs in various forms like electric current in a conductor, charged particles moving through space, and electron mobility in an atomic orbital.

3. Hoopoes

Hoopoes: It is a fascinating birds known for their striking plumage and unique behaviour, have been observed across India, Africa, Europe, and Central Asia.

• About Hoopoes: Belong to the family Upupidae and species Upupa epops; commonly known as Common Hoopoe or Eurasian Hoopoe.
• Distribution: Resident bird of India, seasonally migrates across the subcontinent (e.g., Western Ghats to downhill regions during monsoon).
• Appearance: Crown extends like royal headgear, with black-and-white-tipped crest resembling a Japanese fan.

• Plumage is cinnamon-colored with zebra-striped back and wings, creating a regal appearance.
• Behavior:

o Foraging: Waddles on the ground, inserting its long, down-curved bill into the earth to probe for insects.

o Bathing: Engages in sunbathing and sand bathing.

o Calls: Named after its call, "Hoo-po, hoo-po-po", which echoes repeatedly.

o Fighting: Males fight over nesting sites, jabbing with bills and flaring crests; fights can result in blindness.

o Nesting: Nests in tree trunks or stone wall holes, lined skimpily with grass, leaves, feathers, and rubbish.

o Reproduction:  Breeding season between March and June. Female incubates 5-7 greenish-blue, dirtily speckled eggs; male feeds her during incubation.

• IUCN Red List category: Least Concern

4. Chandrayaan-5 Mission

Chandrayaan-5 Mission: The Centre has recently accorded approval for the ambitious Chandrayaan-5 mission to study the Moon, as announced by ISRO.

• About Chandrayaan-5: This mission is part of India’s long-term goal of achieving an Indian landing on the Moon by 2040 and realising India’s Space Station by 2035.

o Chandrayaan-5 is a collaborative effort between India and Japan (JAXA).

o It aims to explore the Moon’s permanently shadowed regions, which may contain water ice crucial for future lunar exploration and habitation.

• Payload and Design: It will carry a 350 kg Japanese rover and an Indian lander.

o The mission will demonstrate a higher capacity lander, advancing India’s space capabilities.

• Scientific Goals: The rover will study the Moon’s surface and explore the lunar South Pole, a region of high scientific interest.
• International Collaboration: ISRO will provide the lander, while JAXA will develop the rover.

o This collaboration marks a significant step in international cooperation for India’s space program.

• Significance: Chandrayaan-5 represents a major technological milestone and supports India’s pursuit of new scientific discoveries on the Moon.

5. SBI Ecowrap Report

SBI Ecowrap Report: The report (published by SBI's Economic Research Department) released recently, provides a detailed analysis of India's economic landscape in February 2025.

• Key focus: CPI inflation, industrial growth, imported inflation, and corporate performance.
• About SBI Ecowrap Report: It analyses the Indian economy, covering GDP growth, and agricultural reforms, formal and informal economies.
• Highlights a significant moderation in inflation and projects future trends in monetary policy and industrial output.
• About Inflation: Rise in prices of goods and services, leading to decreased purchasing power and erosion of cash value.
• Measurement in India:

o WPI (Wholesale Price Index): Measures price changes at the wholesale level.

o CPI (Consumer Price Index): Measures price changes at the retail level.

• Types of Inflation:

o Demand Pull Inflation: Arises when aggregate demand exceeds aggregate supply.

o Supply Side Inflation/Cost Push Inflation: Occurs when a decrease in aggregate supply raises production costs.

o Headline Inflation: Total inflation, including volatile items like food and energy.

o Core Inflation: Excludes food and energy prices, capturing underlying inflation trends.

o Skewflation: Skewed rise in the price of some items while others remain unchanged.

o Stagflation: Rising prices with falling growth and employment.

• Inflation Targeting:

o Target Setting: Set every five years by the central government in consultation with RBI.

o Target Range: RBI aims to keep inflation between 2% (lower limit) and 6% (upper limit) of CPI.

• State-wise Inflation Analysis: Rural inflation > Urban inflation due to higher food prices.

o Highest Inflation: Kerala (7.3%), Chhattisgarh (4.9%).

o Lowest Inflation: Telangana (1.3%), Delhi (1.5%).
