Hello everyone.. As many of u are continuously asking for the next Anthro batch for CSE 2027. 1. The Anthro foundation for CSE 2027 will be launched in the last week of February.. Its price will be highly affordable for students.. Can't commit as of now, it shall be around 8000 / for full 5.5 months course (including notes) 2. Anthro Mains 2026 enrichment program and test series shall begin immediately after Prelims. Again minimum of the price. 3. GS 3 Mains specific classes for INTERNAL Security, Sci Tech, Environment and Disaster Management will be launched after Prelims 4. Society and Social Issues Classes will be shared on YouTube, free for all. Warm Regards.

Hello everyone. I want to share a personal cum professional information with you all. Tomorrow and day after tomorrow will be the last two days of my official association with Drishti IAS, Karol Bagh. It has been a wonderful journey teaching over there and sharing my bit of effort towards your ambition. I really want to thank Vikas Divyakirti Sir for giving me an opportunity to be a part of this wonderful institution. I want to say a teary bid adieu to Drishti IAS faculty fellows, students and management. I am not going to associate with any other institution in the coming times. Let's go with the flow. Bus Dua me yaad rakhna!!

3. Energy Storage Duration- Optimized for storage between 8 to 24 hours, ideal for grid-level energy management.

Target Prelims 2026: Day 3 1. Bhargavastra: India has successfully tested its first indigenous micro-missile system, Bhargavastra, designed to counter the threat of swarm drones. ● Vehicle-mounted, road-mobile deployment. ● Swarm drones are multiple unmanned aerial vehicles (UAVs) working together as a coordinated system. ● Detection Capability: Capable of detecting small incoming drones at distances exceeding 6 kilometers. ● Terminal guidance with IIR/CCD seekers and lock-on-after-launch (LOAL) capability for micro-munitions. ● Rapid Response: Designed for rapid deployment on mobile platforms. ● Salvo capability and detection: can simultaneously detect and track & engage up to 64 targets. ● Guided Micro Munitions: Utilizes micro munitions that can be guided towards identified threats. 2. Tidal Tail: ● It is a long, thin stream of stars, gas, (mostly hydrogen) and dust that gets pulled away from the main body of a galaxy due to gravitational interactions. ● Gravitational Interactions: Occur during galaxy collisions or mergers. The differential gravitational force pulls stars, gas & dust, creating elongated structures (long, trailing tails- extending for millions of lightyears). ● Tidal Forces: These forces are stronger on the near side of a galaxy facing the other galaxy and weaker on the far side. This difference in gravitational pull stretches the galaxy. ● They often appear curved or arched due to the orbital motion of the interacting galaxies. Some systems have two tails, while others have only one. ● Faintness: They are generally faint and diffuse, making them challenging to observe directly. ● Instruments like the Hubble Space Telescope and James Webb Space Telescope capture high resolution images of tidal tails. 3. Nanopore Technology: Nanopore technology refers to the use of nano-scale pores embedded in a thin membrane to detect and analyze biological molecules. When charged molecules such as DNA or RNA pass through these nanopores, they cause a measurable change in electrical current, allowing real-time detection and characterization. ● A nanopore is an extremely small hole, typically 1–2 nanometers in diameter, embedded in a thin membrane (biological or synthetic). ● A voltage is applied across the membrane. As a charged molecule (DNA/RNA) translocates through the pore, it partially blocks ionic current, producing a distinct signal. These signals are analyzed to determine molecular sequence, length, or modifications. 4. Birefringence (“double refraction”): ** Recent research reveals that there is growing use of Birefringent materials in LCD screens, medical microscopes, optical switches, waveplates, frequency converters, and high-power lasers. ● Birefringence is an optical phenomenon where a single light wave entering an anisotropic material splits into two rays, each traveling at different speeds and refracted at distinct angles. ● Common examples of birefringent materials include: ○ Natural Crystals: calcite, quartz, mica. ○ Biological Structures: Collagen fibers, muscle tissues ○ Engineered Materials: Liquid crystals in LCD screens, certain plastics 5. CO2 battery energy storage technology: NTPC announces the launch of CO2 battery energy storage technology - a pioneering step towards sustainable and innovative energy solutions. This cutting-edge project is spearheaded by NETRA, the R&D wing of NTPC, in collaboration with M/s Triveni Turbine Limited and M/s Energy Dome, Italy. CO₂ battery energy storage is an innovative energy storage system that uses carbon dioxide (CO₂) as a working fluid to store and release energy. It leverages phase changes of CO₂ in a closed system to generate electricity efficiently, without emitting CO₂ into the atmosphere. Working Principle 1. Closed Thermodynamic Transformation: The system operates in a closed loop, manipulating CO₂ between its liquid and gaseous phases. 2. Energy Generation: When energy is required, liquid CO₂ is warmed, causing it to evaporate and expand. The expanding CO₂ drives a turbine, producing electricity.
