Diagnosing cancer with lumninescent bacteria: Engineered probiotics detect tumors in liver

Engineers have devised a new way to detect cancer that has spread to the liver, by enlisting help from probiotics — beneficial bacteria similar to those found in yogurt. Using a harmless strain of E. coli that colonizes the liver, the researchers programmed the bacteria to produce a luminescent signal that can be detected with a simple urine test. —> Read More
