Ultrasound is a machine that gives an early snapshot of baby, and images of what going on inside the body. Researchers have found new development that ultrasound machine can help show tumor growth in the nerve cells of the inside body. If research can do this, they can genetically modify genes when producing a glowing protein of GSP o green fluorescent protein. By using ultrasound, it will give the visual images of a high-frequency sound wave in the body. For example, researches tested the genes by putting into virally altered human kidney cells that they then injected into mice. These cells caused tumors to sprout in the rodents. When the researchers visualized the tumors with GFP, they appeared as green blobs. Ultrasound furnished a more precise image, showing that only cells at the rim of the tumors had turned on the bubble-producing genes", according to the article by Mitch Leslie, "Ultrasound can ''see'' when tumor cells turn genes on and off." This is an excellent article because it shows how reliable an ultrasound machine is that it can detect specific high wavelength and active genes in live cells.
