How to see and touch your own DNA.
Heat-sensitive cameras reveal the hidden diseases of the body. When a healthy person takes his hand out of ice- cold water, his blood will immediately rush to heat the hand. The heat is seen as red and yellow colours through the special cameras. In a person suffering from Raynaud’s disease, the image is very different, as his blood vessels do not function properly. Lack of proper response in the muscles around the blood vessels cut off the blood circulation, and the finger temperature remains around 20 degrees (black in the image).
