What exactly is Horizon Europe? Horizon Europe is the European Union's flagship research and innovation programme with a budget of €93.5 billion for 2021–2027. It is organised around three pillars: Pillar I – Excellent Science: Supporting frontier research, researchers and scientific infrastructure. Pillar II – Global Challenges and European Industrial Competitiveness: Addressing challenges in health, climate, energy, AI, food security and industry. Pillar III – Innovative Europe: Supporting innovation, start-ups and the growth of innovative businesses. India's proposed association covers Pillar II. But what opportunities could this create for Indian researchers and institutions? 🧵

India's association with Pillar II could open opportunities in: 1.Research funding: Participation in eligible collaborative research projects. 2. Technology: Cooperation in AI, biotechnology, clean energy and advanced industries. 3. Global collaboration: Partnerships between Indian and European universities, researchers and institutions. Innovation: Stronger research and industry linkages. UPSC connection: • GS-II: India–EU relations and science diplomacy. • GS-III: Research and development, emerging technologies and innovation. The association is yet to be formally signed and operationalised.

The smartest strategies from AIR 1s worth adopting: 3rd: Killing the material greed Just one basic book per subject, revise on repeat. Shruti Sharma spent twice as long checking her mistakes as writing the test, and stopped confusing herself with new material.

2nd: Freezing Mains on December 31st Your notes will never feel complete. Instead of writing practice answers into January, Kanishak Kataria locked his Mains prep on New Year’s Eve. That hard stop gave him a clear head to focus fully on Prelims.

The top-ranked one: Taking CSAT seriously before it hurts Aditya Srivastava had a top engineering degree, but never assumed basic math would save him. He tested himself early, saw how tricky the logic and reading passages were, and gave them regular weekend hours.

10 years of Demonetisation, by the hard numbers: ​3rd: Tax Formalisation Goal: Lift the tax-to-GDP ratio and boost tax buoyancy. ​But, Tax-to-GDP only crawled from 11.1% to 11.4%, while tax buoyancy remained completely stagnant post-2016.

2nd: The "Less-Cash" Shift ​The Goal: Reduce physical currency usage through digital adoption. ​UPI transactions exploded to ₹314 lakh crore. ​But, Currency in circulation climbed back to ₹43.2 lakh crore, remaining flat at 12% of GDP. Digital apps grew fast, but physical cash never actually vanished.

No.1 reality: Ending Black Money The core objective was destroying hoards of illicit wealth. Instead, 99.3% of demonetised notes returned to banks. It proved black money was parked in real estate, gold, and businesses, not stored in physical cash

The Quad is gradually expanding its focus beyond traditional maritime security. At the recent Foreign Ministers' meeting, the four countries announced the Quad Business Leaders Forum with a focus on critical minerals, semiconductors and trusted AI.

The latest developments point to three key areas of Quad cooperation: • Economic security: Building resilient global supply chains. • Critical minerals: Recovering minerals from e-waste and reducing dependence on single suppliers. • Emerging technology: Cooperation in trusted AI and advanced communication technologies like 5G and 6G. The Quad is increasingly linking regional security with economic and technological resilience. And what does this mean for India?👇
