Bacteriophages, also known as ‘phages,’ are the most common lifeform on the planet. They are constantly hunting for bacteria to infect and kill. What if we could harness these tiny microbes to help us in our fight against harmful, disease-causing bacteria? On this episode of The Show About Science, Ben Chan, from Yale University, joins Nate to explore the potential of phages in treating human infections amid the declining effectiveness of broad-spectrum antibiotics.
