Maglev trains are one of the greatest inventions in man-made history. These trains float over the track using magnetic power. The name Maglev is an abbreviation of Mag netic Lev itation. As there is no contact between the train and the track, these type of trains moves faster with minimum energy loss. These trains are also well known for their eco-friendly operation, as it does not use any petroleum products like petrol, diesel, etc. From the year 1902, magnetic levitation has begun to rule the world. In 1984, the first commercial maglev train was introduced in Birmingham, the UK, with levitation of 15mm and a track length of 600m. From the past to the present, there were several breakthroughs made in maglev technology. These breakthroughs were successfully implemented at present in three countries; namely China, South K...
A cell is the building block of a living thing. Every living thing is made up of tiny little cells. Especially humans have a very large amount of different types of cells like skin cells, muscle cells, sperm cells, egg cells and other cells. All these cells have the same basic parts like cell membrane, cytoplasm, endoplasmic reticulum, mitochondria, nuclear membrane, nucleus and more. Here the nucleus is considered as the main part of the cell. Inside the nucleus, there is a thread-like structure called chromatin which is made up of DNA (Deoxyribo Nucleic Acid) wounded around proteins called histones. These chromatins are essential for our life to sustain. The DNA in the nucleus decides the way our life should evolve. The DNA stores all the information about our body and the operations that need to be performed by each cell.

Jet streams are fast-flowing winds that circulate over the globe at a higher atmosphere. It is the part of global air circulation situated over the tropopause. Global air circulations are one of the primary things established under three cell categories to redistribute the heat all over the globe. Jet streams are formed during these redistributions. The major jet streams that form via the global air circulation are subtropical jet streams and polar jet streams. The subtropical jet stream originates at the subtropical region, and the polar jet stream originates at the subpolar region. These jet streams are permanent winds that exist in both the northern and the southern hemispheres, and flow around the globe all around the year.
