The lethal beauty of viruses and bacteria
Caught under the microscope
© Getty Images
Far too small to be seen by the human eye, viruses and bacteria are identified by being placed under the microscope by scientists who use false color to enhance the detail of these infectious agents and single-cell organisms. The resulting images appear as miniature works of vibrant abstract art that could grace the walls of any contemporary gallery. Except in real life you wouldn't want to be anywhere near this harmful subject matter!
