🦠 Using Bacteriophages to Combat AMR 📍 Background ✅ Antibiotics are losing effectiveness; 5 million die annually from AMR, may double by 2050. ✅ No major pharma investment in new antibiotics due to low financial incentives. 📍 Bacteriophages as Solution ✅ These are “good viruses” that kill bacteria; found in soil, water, gut. ✅ Can be used for burns, UTIs, respiratory infections etc. 📍 Strategies ✅ 1. Isolate bacteria, grow matching phage in lab, administer to patient. ✅ 2. Use pre-engineered phages to match bacteria types. ✅ Phage therapy is being revived, especially in Eastern Europe. 📍 Global Need ✅ No Western country has approved phage as drug yet, but emergency/special access routes exist. ✅ Magistral route in Belgium allows compounded phage medicines per patient.

🔆 Space-Based Surveillance (SBS) 📍 What is SBS? ✅ Aim: Strengthen land and maritime awareness for civilian and military purposes. ✅ Applications: Earth and outer space monitoring, environmental, disaster, scientific research, traffic control. 📍 Evolution of India’s SBS Program ✅ SBS-1 (2001): Focused on basic surveillance (Cartosat-2A, Cartosat-2B). ✅ SBS-2 (2013): Enhanced capabilities (Cartosat-2C, RISAT-2). ✅ SBS-3 (2024): 52 satellites for real-time multi-domain surveillance; focuses on maritime monitoring. Linked with Predator drones. 📍 Challenges ✅ Dual-use Tech: Civilian vs. military ambiguity. ✅ Militarisation of Space: Risk of arms race. ✅ Privacy Risks: High-res satellites may intrude privacy. ✅ Legal Gaps: Outdated treaties. ✅ Diplomatic Tensions: Unauthorized surveillance. 📍 Applications & Global Developments ✅ National Defence: Monitors launches, borders, troop movements. ✅ Space Traffic: Prevents satellite collisions. ✅ Disaster Management: Floods, wildfires, ocean health. ✅ Scientific Observation: Long-term mapping and resource monitoring. #GS3 #science_and_technology

🔆Germanium: ✅It is a chemical element between silicon and tin in Group 14 (IVa) of the periodic table. It has the chemical symbol Ge and the atomic number 32. ✅It is a silvery-gray metalloid, intermediate in properties between the metals and the nonmetals. ✅It has a diamondlike crystalline structure, and it is similar in chemical and physical properties to silicon. ✅Germanium is stable in air and water and is unaffected by alkalis and acids, except nitric acid. ✅Although germanium was not discovered until 1886 by Clemens Winkler, a German chemist, its existence, properties, and position in the periodic system had been predicted in 1871 by the Russian chemist Dmitry Ivanovich Mendeleyev, who called the hypothetical element ekasilicon. ✅Germanium use in semiconductors. ✅It remains of primary importance in the manufacture of transistors and of components for devices such as rectifiers and photocells. #gs3
