Researchers at Tel Aviv University have completed research that will enable the use of cameras to capture colors that are invisible to the human eye. Many gases and substances such as hydrogen, sodium and carbon have their own color in the infrared spectrum, but human beings can only pick up certain photons to see color. This is a huge advancement because it may make it easier to detect cancer cells. The discovery may also make the technology affordable (i.e., used in a simple camera) and applicable in multiple ways, such as detection of pollutants and explosives, as well as disease.
