VK IAS - (Science and technology)

✅Gs-3 : Science and technology- Protein Biosensors- Use case 🅾️It is like an ultra-smart security scanner. Instead of checking everyone, it instantly recognizes only the person it is looking for. FOr this scientists are using aptamers ⚠️Whats the process?- this is imp for prelims- Click here 🔰Science and Tech news : https://t.me/sciencehighlights 🎖Please Subscribe : Youtube.com/vikaskanukollu

✅Gs-3 : Science and technology- Concept of jumping genes which explains many modern biological problems. 🅾️What?- Jumping Genes (Transposons) are segments of DNA that can move or replicate themselves to different positions within a genome. Discovered by Nobel laureate Barbara McClintock in maize, they make up about 50% of the human genome and play a major role in genetic diversity, evolution, and disease. 📌Useful in explaining ⚜️1. Anti Microbial Resistance- Click here ⚜️2. EVolution of cancers- Click here ⚠️Prelims version of this concept- Click here 🔰Science and Tech news : https://t.me/sciencehighlights 🎖Please Subscribe : Youtube.com/vikaskanukollu

✅Gs-3 : Science and technology 🅾️First DNA Vaccine for Dengue- https://t.me/upschighlights/5492 - Note that India has developed a DNA vaccine candidate for dengue, but DengiAll is not a DNA vaccine. DengiAll is a live attenuated tetravalent dengue vaccine candidate undergoing Phase 3 trials. ⚜️The Brazil-related concern applies mainly to DengiAll-type live attenuated tetravalent dengue vaccines, not directly to India’s separate DNA dengue vaccine candidate. ⚠️VK IAS subject wise channels - Click here 🎖Please Subscribe : Youtube.com/vikaskanukollu

✅Gs-3 : Science and technology ✅Gs-3 : Environment and climate change- biotechnology, disease resistance 🅾️This article is useful because it connects 3 syllabus areas that UPSC increasingly links together-Environment and climate change → Public health → Science and technology 🅾️When drought dries soil, natural antibiotics in soil become more concentrated. This creates selection pressure. Resistant bacteria survive, multiply and spread resistance genes. This can worsen antimicrobial resistance, especially in drought-prone countries like India. 📌For prelims : Horizontal Gene Transfer- high-value Prelims concept. It means bacteria can transfer genes to other bacteria without reproduction. Common modes include : ⚜️Transformation: uptake of DNA from environment ⚜️Transduction: transfer through viruses ⚜️Conjugation: direct transfer through cell contact ⚠️VK IAS subject wise channels - Click here 🎖Please Subscribe : Youtube.com/vikaskanukollu

✅Gs-3 :Science and Technology—Achievements of Indians in Science & Technology; Indigenization of Technology. 🅾️A satellite navigation system requires at least four satellites to provide a 3D position (Latitude, Longitude, Altitude, and Time). With the failure of the clock on IRNSS-1F on March 13, 2026, the number of functional satellites has dropped to three. The friction lies in the reliability of imported Swiss-made (SpectraTime) rubidium clocks, which have seen a high failure rate across the constellation. 🅾️NavIC is the backbone for Indian Standard Time (IST) dissemination and critical for "missile guidance" and "troop movement" in conflict zones where foreign systems like GPS (USA) or GLONASS (Russia) could be denied. For the common citizen, it powers vehicle tracking systems and disaster management alerts. ⚠️VK IAS subject wise channels - Click here 🎖Please Subscribe : Youtube.com/vikaskanukollu

✅Gs-3 : Science and technology- AI- Graphic processing Unit- Nvdia 🅾️GPUs are specialised parallel processors designed to perform massive numbers of similar calculations simultaneously. That architectural design makes them central to AI, high-performance computing, and modern digital infrastructure ⚠️Why do they matter?- A CPU is designed for versatility. It has a small number of powerful cores optimised for sequential, logic-heavy tasks. A GPU, in contrast, has thousands of smaller cores built for parallel processing. Instead of completing one complex task quickly, it completes thousands of similar tasks at once.Modern AI models are built on neural networks. Neural networks repeatedly multiply and add matrices. 🔰Matrix multiplication = millions of identical arithmetic operations.GPUs excel here because they can perform multiply-accumulate operations simultaneously across thousands of cores. 🎖VK IAS subject wise channels - Click here ⚠️Youtube : Click here and join the VK IAS channel

✅Gs-2 IR- India- US -Bilateral agreements (India–US)- International trade and its impact on domestic policies. ✅Gs-3 : Agriculture- ✅Gs-3 : Science and tech- Genetically Modified crops, Biotechnology ⚠️Mains patterns to note 🅾️Pattern A: Rapid urbanisation and rising incomes are shifting Indian diets toward animal proteins (milk, eggs, meat). This drives a massive demand for maize and soybean de-oiled cake. However, India's push for 20% Ethanol Blending (E20) by 2025-26 is diverting maize away from the feed industry, creating a supply-demand gap. 🅾️Pattern B-The dilemma- Read here 🅾️Pattern c-Click here and read Indo-US Bilateral Friction-.High tariffs (up to 50% on maize) and strict bio-safety regulations under the Environment Protection Act, 1986 serve as non-tariff barriers. 🔰Prelims pointers : Click here to read about trends in animal feed industry 🎖VK IAS subject wise channels - Click here ⚠️Youtube : Click here and join the VK IAS channel

✅Gs-3 : Science and technology- “Dark Sky” Conservation-Hanle (Ladakh) is India’s first Dark Sky Reserve 🅾️Astronomy thrives where the night sky remains naturally dark , free from light pollution, aerosols, and atmospheric disturbance. 🅾️Geophysical Advantage: ⚜️High altitude (~4,500 m) → low humidity and minimal aerosols. ⚜️Thin atmosphere → greater light clarity for telescopic observation. ⚜️Few artificial light sources → ideal for deep-sky astrophotography @hinduhighlights for News analysis @upschighlights - Relevant hashtags for Prelims- Click here 🎖Please Subscribe : Youtube.com/vikaskanukollu

✅Gs-3 : Science and technology 🅾️Q) The evolution of geolocation technology from a civilian tool to a strategic weapon has redefined the nature of both security and surveillance.

#SnT ✅What is Goldene? 🅾️ It is a single-atom-thick sheet of gold, making it the world's thinnest gold leaf. 👉🏻Read about graphene here- Click here 🅾️Scientists have been trying to make 2D sheets of metals like this for a long time 🅾️Sensing different chemicals and substances-Catalysis - speeding up chemical reactions (like splitting water for clean energy). ⚠️Why is it significant?- Gold at this thinness has completely new properties, unlike the gold we usually think of.Bulk gold is 3D, with atoms arranged in all directions. Goldene is 2D, where atoms are confined to a single flat sheet. This fundamental difference in structure can dramatically alter its electrical, optical, and chemical behavior-can lead to new electronic properties, potentially making goldene more efficient at conducting electricity or interacting with light in specific ways. ⚡️VK IAS subject wise channels - Click here ⚠️Youtube : Click here and join the VK IAS channel

#SnT ✅Semiconductors manufacturing Technology 🅾️What is a semiconductor chip? How is it manufactured? ⚜️A semiconductor has properties between a conductor (which conducts electricity) and an insulator (which does not). In its purest form a semiconductor is a very weak conductor of electricity. ⚜️However, its electrical properties can be changed by adding small amounts of certain substances called ‘dopants’. By taking a pure semiconductor and carefully injecting certain parts with specific dopants, complex circuits can be ‘printed’ on the semiconductor. 🎖VK IAS subject wise channels - Click here ⚠️Youtube : Click here and join the VK IAS channel

#Polity ✅Extra Neutral Alcohol 🅾️Primary ingredient for alcoholic beverages (whiskey, vodka, etc.) 🅾️It is derived from different sources — sugarcane molasses and grains — and is used in the production of alcoholic beverages such as whisky, vodka, gin, cane, liqueurs, and alcoholic fruit beverages. 🅾️Colorless, food-grade alcohol with neutral taste and smell=Also used in cosmetics, personal care products, and some industrial applications. 🅾️ENA is a byproduct of sugarcane processing, similar to ethanol- Issue is Diversion of ethanol (a byproduct of the sugar industry, like ENA) to biofuel blending. ✅Think of it like this: ⚜️Sugarcane Molasses: The raw material. ⚜️Ethanol: The first level of refinement-95% ⚜️ENA: Ethanol further refined to a higher purity to meet specific requirements-96%pure and above. ⚡️VK IAS subject wise channels - Click here ⚠️Youtube : Click here and join the VK IAS channel
