| 1 | This approach uses fluorescence instead of magnetism to image samples. | |
| 2 | A fluorescence microscope can then detect even a tiny amount of the virus. | |
| 3 | Other machines usually detect the bases by attaching fluorescent dyes to them and using a camera. | |
| 4 | Change your light bulbs: Use compact fluorescent light bulbs (CFL) instead of the standard light bulbs. | |
| 5 | Researchers hope such animals will help scientists track the course of disease via fluorescence. |
