Scientists from the University of California San Diego, in collaboration with their Australian colleagues, have engineered a bacterium with the capability to detect the presence of tumor DNA in a live organism. This innovation, which has successfully detected cancer in the colons of mice, was detailed in the journal Science on August 11th, 2023. It holds the potential to lay the foundation for advanced biosensors that might identify a range of infections and other diseases. Historically, bacteria have been modified to perform various diagnostic and therapeutic functions. However, their capability was limited, lacking the precision to identify specific DNA sequences … Continue reading Bacteria’s New Superpower: Detecting Cancer DNA!
