Recently, scientists have discovered a way to detect viral diseases, such as HIV, using glow-in-the-dark proteins. This new method, which is based on genetic engineering, allows researchers to detect the presence of the virus without relying on traditional laboratory tests. By introducing fluorescent proteins into cells infected with a virus, the researchers can see a “glow” in the dark, indicating the presence of the virus. This method could provide a faster, more accurate way for diagnosing and treating viral diseases, as well as help to understand how the virus is spreading in the population.
