International Relations and Issues

SAVE America Act

President Donald Trump cites India’s voter cards to make case for SAVE America Act.

• Background – Praised the Indian election system that “Over 646 million people participated in the recent general elections in India, and yet less than 1% voted through postal ballots.”
• Proposal – Act seeks proof of citizenship to register, link voter ID cards to a biometric database, nationwide voter ID, limit voting by mail.
• Debate – Bill faces division in Congress; Senate adjourned without action.

US Debt Update 2026 – USD 40 Trillion

US government debt tops USD 40 tn, rising at historic pace.

• Record – Gross federal debt crossed USD 40 tn, up USD 3tn in a year.
• Public Debt – Now exceeds USD32tn, equal to US economy size.
• CBO Forecast – Debt to hit 120% of GDP by 2036.
• Impact – Servicing cost now exceeds defence spending; borrowing costs at multi‑decade highs.
• Policy – Treasury doubling long‑term debt purchases; Trump’s tax cuts & defence hike add pressure.
• Concern – Analysts warn of vicious cycle of rising interest expense; daily debt rise USD 7.9bn.

Economy

Tilapia Products Export – Chhattisgarh

Chhattisgarh became the 1^st inland state in India to begin exports of value‑added Tilapia products.

• Cluster Approach – Government developing 34 fisheries clusters under PMMSY for production, processing, exports.
• Achievement – Chhattisgarh initiated exports with 382 tonnes of Tilapia to USA.
• Tilapia hatchery produces quality seed and develops genetically improved black strain Tilapia.

Coal’s New Flex

India adds renewable capacity fast, but grid still relies on coal-fired plants; flexible thermal power needed.

• Demand – Peak demand rose from 135 GW (2013) to 270 GW (2026).
• Renewables – By Nov 2025, half of installed capacity non‑fossil fuels; solar surpassed 160 GW, share 8.9% (2025‑26).
• Challenge – Grid cannot absorb all clean power; coal plants designed for base‑load, struggle with variable demand.
• Duck Curve – Solar peaks midday but demand peaks evening hence there is a steep gap.

Sugar Import by India – 2026

India to import sugar for 1st time in 10 years,  Government allows import of 10 lakh tonnes raw sugar.

• Reason – Low opening stock 35–40 lakh tonnes vs 50 lakh tonnes (2025); production fell to 296 lakh tonnes, lowest since 2019‑20.
• Consumption – Annual demand 280 lakh tonnes; net production projected 290 lakh tonnes (2025‑26).
• Measures – Stock holding limits on bulk consumers & dealers (Sept–Nov); weekly stock declaration mandatory.
• Significance – India ranks 2^nd and also consumes a huge share of its own supply.

Environment

High‑Risk Human‑Elephant Conflict (HEC) Areas in Southern Africa

A new study forecasts, HEC areas in Southern Africa could expand by 33%–100% by 2085.

• Study – Analysis on records from Namibia, Botswana, Angola, Zambia.
• Drivers – Human population growth, cropland expansion, climate‑related drying.
• Findings – Crop raiding seasonal, wet‑season conflict 10× higher; hotspots near Etosha NP, Zambezi Region, Okavango Delta.
• Impact – Expansion threatens 290,000 savanna elephants and rural livelihoods.
• Need – Proactive land‑use planning, early‑warning systems, community‑based mitigation.
• Global Context – Human‑wildlife overlap projected across 56% of world’s land by 2070.

Science

China’s LandSpace Rocket

China’s LandSpace lands rocket booster; joins SpaceX, Blue Origin with reusable tech.

• Event – Zhuque‑3 rocket 1^st stage successfully landed in Gansu  in 2^nd attempt.
• Significance – China’s 1^st private firm to recover orbital‑class booster.
• Tech – Stainless‑steel body (heat‑resistant, cost‑efficient); runs on methane + liquid oxygen (cleaner fuel).
• Purpose – The ability to return, recover and reuse a booster is crucial to reduce cost.
• Make ​it easier to put satellites into orbit, turning space exploration into a commercially viable business similar to ​civil aviation.
• Capacity – Lifts 14.2 metric tons to LEO.

Fastest Star in Milky Way – S301

Recently, Astronomers detect fastest known star in Milky Way, S301.

• Speed – Travels at 25,000 km/s (8% of light speed), 100,000× faster than a plane.
• Orbit – Tight orbit around Sagittarius A*, completes in 8.7 years, distance Saturn–Sun.
• Discovery – Observed using the European Southern Observatory’s Very Large Telescope Interferometer (ESO’s VLTI) at the Paranal Observatory in Chile,
• Orbit traced since 2017, next close passage in 2031.
• Significance – Closest known star to central black hole; enables direct test of Einstein’s relativity.
• Impact – Could measure black hole spin, opening new window on Milky Way evolution.

Mega‑Earth GJ 523b

Recently, Scientists discover Mega‑Earth GJ 523b, 2.5× Earth’s size with core 23× Earth’s mass.

• Discovery – Found by Wisconsin Center for Origins Research (WiCOR), , using NASA TESS, WIYN telescope, JWST.
• Age – 170 million years; first catalogued exoplanet by WiCOR.
• Features – Rocky, dense planet, massive core, avoided expected hydrogen‑rich atmosphere.
• A mass 23 times Earth's, while the planet itself is about 60% the size of Neptune.
• Puzzle – Raises questions on planet formation, atmosphere loss, collisions, proximity to star.
• Significance – Defines Mega‑Earth category, challenges ideas of rocky vs gas‑rich worlds.
