The Annual Status of Education Report (ASER) 2024 was released by Pratham NGO.

• Methodology: Uses 2011 Census data to select 30 villages per district and 20 households per village. Surveys children aged 3-16 years.
• Reading improvement:
  • Class 3 students who can read Class 2-level text: 16.3% (2022) to 23.4% (2024).
• Arithmetic improvement:
  • Class 3 students who can do subtraction: 28.1% (2018) to 33.7% (2024).
• Digital access: 89% of 14-16-year-olds have smartphone access; 57% use it for education.
• Government school enrolment: Fell from 72.9% (2022) to 66.8% (2024). Private school enrolment increasing.
• Relevant schemes: NIPUN Bharat Mission (Foundational Literacy and Numeracy) and NEP 2020.

Chinese AI startup DeepSeek released DeepSeek-V3 and DeepSeek-R1, disrupting assumptions about AI development costs.

• Key claim: DeepSeek-R1 achieves reasoning performance comparable to OpenAI's o1 model at a fraction of the cost.
• Reinforcement Learning: DeepSeek automates the "Reinforcement Learning from Human Feedback" (RLHF) process, reducing the need for expensive human annotators.
• Impact: The announcement caused significant falls in US AI-related stocks, including Nvidia, as it questioned the assumption that only massive chip investment could produce frontier AI.
• India context: India has over 4,500 AI startups. The DeepSeek development vindicates the idea that smaller, more efficient models can be built without the compute scale of the US.
• Edge computing: Small Language Models (SLMs) from advances like DeepSeek can run on edge devices without cloud dependency.

ISRO's GSLV-F15 successfully launched the NVS-02 satellite, marking ISRO's 100th launch.

• Satellite: NVS-02 is part of the NavIC (Navigation with Indian Constellation) system.
• Orbit: Placed in Geosynchronous Transfer Orbit (GTO), final orbit at 36,000 km (geostationary).
• NavIC: India's indigenous satellite navigation system. Provides positioning accurate to 20 metres for users in India and up to 1,500 km beyond its borders.
• ISRO launch vehicles:
  • PSLV (1994): Polar Satellite Launch Vehicle, workhorse for remote sensing satellites.
  • GSLV (2001): Geosynchronous Satellite Launch Vehicle, uses cryogenic upper stage.
  • GSLV Mk III / LVM3 (2014): Carries up to 4,000 kg to GTO.
  • SSLV (2022): Small Satellite Launch Vehicle for nano and micro satellites.

A stampede on Mauni Amavasya (29 January 2025) at the Prayagraj Maha Kumbh Mela killed 30 people and injured 60.

• Day significance: Mauni Amavasya is the most important bathing day at Maha Kumbh. Pilgrims observe a vow of silence (maun). Tens of millions congregate at the Sangam.
• Causes of stampede: Weak crowd control barriers, panic triggered by pushing near entry points, underestimation of crowd density, and poor inter-agency coordination.
• NDMA guidelines for mass events:
  • Crowd estimation with sensors and CCTV.
  • Entry point regulation and one-way crowd flow.
  • Pre-positioned medical teams and ambulances.
  • Emergency exits clearly marked.
• Statistical context: 79% of stampedes in India have occurred during religious events.

The World Health Organisation issued guidelines recommending replacement of regular table salt with lower-sodium substitutes.

• Recommended substitute: Potassium chloride (KCl)-based salts, sold as "low-sodium" or "heart-healthy" salts.
• Sodium target: WHO recommends reducing sodium intake to less than 2 grams per day (equivalent to 5 grams or about one teaspoon of salt).
• Exclusions: The recommendation does not apply to pregnant women, children, and those with kidney disease (since excess potassium is harmful for people with kidney failure).
• Context: High sodium intake is linked to hypertension (high blood pressure), which is a leading risk factor for cardiovascular disease and stroke.

The Bhashini platform expanded its integrations with government services.

• What is Bhashini: An AI-powered language translation platform for India's 22 scheduled languages.
• Developed by: Digital India Bhashini Division (DIBD) under MeitY.
• New integrations: CM Helpline portals, eVidhan (state legislature documentation), and e-Districts.
• Features: Real-time translation, speech-to-text, text-to-speech, and voice-to-voice translation.
• Significance: Enables citizens to access government services in their preferred language, bridging the digital language divide. Aligns with NEP 2020's emphasis on mother-tongue-based education.

• WASP-127b: An exoplanet with jet-stream winds recorded at 33,000 km/h, the fastest ever measured in any atmosphere. It is a Hot Jupiter type planet (30% larger than Jupiter, 16% of its mass). Tidally locked, it has extreme day-night temperature contrasts.
• SEBI "When-Listed" Platform: SEBI's initiative for regulated pre-listing share trading within a T+3 timeline (allotment to listing). Replaces the informal grey market in unlisted shares.
