Scientists developed the first implantable artificial kidney in the world. The artificial kidney contains a microchip filter and living kidney calls that can run using the patient's heart. The bio-hybrid kidney mimics the real organ by removing salt, water and waste products to keep patients from relying on dialysis. At the heart of the artificial kidney lies the microchip called silicon nanotechnology. Each artificial kidney contains 15 microchips in layers that are used as filters and a support system wherein the living cells will be placed. Dr. William H. Fissell IV explained that kidney cells can be grown in a laboratory dish and nurtured into a bioreactor of living cells. This will then become the 'Santa Claus' membrane that can distinguish 'naughty' and 'nice' chemicals.   they can reabsorb the nutrients your body needs and discard the wastes your body desperately wants to get rid of," said Fissell, an associate professor of

A new blood test that detects five different forms of cancer is one step closer to becoming a reality and could save millions of lives around the world. The team of scientists developing the new diagnostic tool have branded their discovery of a 'striking DNA signature' in five forms of the disease, an 'important step'. The signature occurs in colon, lung, breast, stomach and endometrial cancers, researchers at the National Human Genome Research Institute found. When tumors develop in any of these areas, one specific gene - known as' ZNF154 '- changes its chemical signature. It raises hopes that a simple blood test to diagnose these, and other forms of the disease, may become a reality in the near future. Researchers found when a person was suffering cancer, higher amounts of methylation occurred - a process where a gene is switched 'off'. They describe methylation as controlling the expression of genes 'like a dimmer on

Bonsai is the art of aesthetic miniaturisation of trees and plants in containers. In Japanese a Bonsai, means “tray-planted”. A bonsai plant is not a dwarf plant but equal to the full sized flowering plant. The main objective of bonsai plants is to create a tree or plant, and even landscapes, in miniature. The flowering perennials grown as bonsais are called as Flowering Bonsais.  flowering Bonsai plant need feeding, watering, pruning and training at regular interwals for its healthy growth. The bonsais are grown in small containers to get a desired shape by the application of wire coils. The three most essential aspects to be considered when we go for a bonsai are - 1) the selection of containers, , 2) the position of the plant in the container, and 3) the choice of the plant variety.   There are four sizes of flowering bonsais : miniature, small, medium, and average. Miniature bonsais range grow to 2 inches in height, maturing in about five years. Small
