National Cancer Awareness Day 2025

Why in News?  

India observes National Cancer Awareness Day on 7th November 2025, focusing on prevention, early detection, and awareness of cancer. 

Key Points 

• Date and Background: 
  • The day coincides with the birth anniversary of Marie Curie (7th November 1867), whose groundbreaking research on radioactivity revolutionized cancer diagnosis and treatment. 
  • It was first announced in 2014 by the Union Ministry of Health and Family Welfare to promote awareness about cancer prevention and screening. 
• Purpose and Significance: 
  • Aims to educate citizens on the importance of lifestyle modification, regular health check-ups, and timely medical intervention. 
  • Cancer cases in India are rising, with over 14 lakh new cases reported each year, many detected at advanced stages. 
• Theme 2025: Though India’s campaign has a domestic focus, it aligns with the global World Cancer Day theme (2025–27): “United by Unique”, highlighting personalized care and inclusivity in cancer treatment.

Maria Skłodowska-Curie (1867–1934) 

• Nationality: Polish-born, later became a French citizen 
• Major Discoveries: 
  • Discovered the radioactive elements Radium (Ra) and Polonium (Po). 
  • Pioneered the concept and medical use of radioactivity in cancer treatment (radiotherapy) 
• Awards and Honours:

Google’s Project Suncatcher

Why in News?  

Tech giant Google has announced Project Suncatcher, an ambitious research initiative to develop AI-powered data centres in space. 

Key Points 

• About Project Suncatcher: 
  • Project Suncatcher envisions solar-powered satellites hosting AI data centres in space to reduce Earth’s energy and water consumption used for cooling terrestrial facilities. 
  • These orbiting data centres will use free-space optical links to transfer data at speeds of tens of terabits per second, forming a distributed network similar to satellite internet constellations like Starlink. 
  • Google plans to launch two prototype satellites by early 2027 to test its space-based TPU (Tensor Processing Unit) hardware. 
• Rationale for Space-Based AI Centres: 
  • AI data centres consume enormous electricity and water for cooling — a growing environmental concern as AI adoption increases globally. 
  • In space, solar panels are up to 8 times more efficient than on Earth, providing a continuous and clean energy supply. 
• How It Works: 
  • The satellites will rely on solar energy and optical data transmission to function as a cohesive high-performance computing network. 
  • TPUs (Trillium v6e) are being tested for radiation resistance and performance in extreme conditions.
