  ✅ Why in News :  Usage of Indian Regional Navigation Satellite System(NavIC system) has increased in sectors like transportation and personal mobility. 🔸There is also an increase in the number of NavIC enabled smart mobile phone models in the Indian market. ▪️About Indian Regional Navigation Satellite System ( IRNSS )  ✅IRNSS is an independent regional navigation satellite system developed by the Indian Space Research Organization (ISRO). ✅The main objective is to provide reliable position, navigation and timing services over India and its neighbourhood. ✅IRNSS is a regional and not a global navigation system. ✅Unlike the widely used GPS which includes 24 satellites, NavIC has 8 satellites and their range is within India and its adjoining regions extending up to 1,500 km from the country’s border. ✅Technically satellite systems with more satellites provide more accurate positioning information. However, compared to GPS which has a position accuracy of 20-30 metres, the...

 COFFEE-RING EFFECT Researchers have given new insights on the ‘coffee-ring effect’. ✅For about two decades now, the ‘coffee ring effect’ has been known as when a drop of spilt coffee dries up, the outermost edge of the dried drop is a little darker than the centre, forming a darker ‘ring’. ✅This is caused by the outward drift of suspended coffee particles from the centre, causing a denser, darkened rim. ✅Now, researchers from Indian Institute of Technology, Madras, have shown that after reaching the rim, as the drop dries, some of the particles undergo an inward drift too. ✅This research has applications in agriculture, forensic science and even disease diagnosis. The present work has been published in the journal, Soft Matter.

  🔆Carbon Dating Method ✅ The District Court in Varanasi allowed a petition seeking Carbon Dating of the structure inside the Gyanvapi mosque that the Hindu side has claimed is a ‘ Shivling ’. ▪️What is Carbon dating? ✅It is a widely-used method applied to establish the age of organic material, things that were once living.  ✅Living things have carbon in them in various forms.  ✅The dating method makes use of the fact that a particular isotope of carbon called C-14, with an atomic mass of 14, is radioactive, and decays at a rate that is well known. ✅The most abundant isotope of carbon in the atmosphere is carbon-12 or a carbon atom whose atomic mass is 12.  ✅A very small amount of carbon-14 is also present. ✅Process : Plants get their carbon through the process of photosynthesis, while animals get it mainly through food. Because plants and animals get their carbon from the atmosphere, they too acquire carbon-12 and carbon-14 isotopes in roughly the same proportion a...
