Supernova

Image
If a bright star burst into view in a corner of the night sky which was not there just a few hours ago, but now it burns like a beacon.   That star was not actually a star, but is the brilliance of explosion of that star when it has reached the end of its life known as supernova. A supernova is an event which takes place in the space due to explosion of star. It is the biggest and largest explosion that humans have ever seen. Each of such blast is super-powerful, extremely bright explosion of a star. Energy of supernova is that high that it can outshine entire galaxy for a short time and can radiate more energy that sun will in its entire lifetime. Supernovas are often seen in other galaxies.   Supernovas are difficult to seen in this milky way galaxy due to dust particles which blocks the view. Supernova was last observed in the Milky Way in 1604 which was discovered by Johannes kepler.   Remains of most recent supernova were discovered by Chandra telescope develo...

Gene therapy

Image
Gene is a hereditary unit which is transferred from parent to off spring and is responsible for determination of some characteristics of offspring’s. The technique was first developed in 1972 but has, so far, had limited success in treating human diseases. Gene therapy is a technique which uses genes to prevent or treat the disease. This is an experimental technique, which in future, is expected to allow doctors to treat disease/disorder by introducing a gene into the cell of patient instead of drugs and surgery. Gene is made up of DNA. When a new DNA is introduced into the cell of patient to treat a genetic disorders the technique is called gene therapy.   Diseases are mostly caused by disease-causing mutated genes, usually new DNA contains a functional gene to correct the effect of mutation caused by mutated gene. The DNA is selected carefully to correct the disease causing gene. Gene therapy is a topic of interest now a days, as many research approaches are testing includi...
