This episode: Intricate networks of tunnels in garnet gemstones seem to have come from tunneling microorganisms!
This episode: Bacteriophages with defenses against bacterial CRISPR defenses have to work together to succeed!
This episode: Some bacteria produce DNA-targeting toxins, which provokes a similar retaliation from other strains. Sometimes this hurts the provoker, but sometimes it is very helpful to them!
This episode: A new giant virus infecting marine algae brings its own genes related to fermentation, generating energy in the absence of oxygen!
This episode: The bacterial immune system, CRISPR-Cas, can enhance gene transfer via transduction (phages carrying bacteria DNA) despite preventing it via conjugation!
This episode: Very small ocean algae consume bacterial prey of a similar size to themselves by engulfing them only partially!
This episode: Some bacteria living around plants can become pathogenic just by gaining a few genes!
This episode: Fecal microbiota transplants work just as well when taken in pill form as when delivered through a tube!
This episode: Gut microbe transplants from wild mice protect lab mice from disease!
This episode: A simplified bacterial community in mouse guts doesn’t have much community structure, relative to other body areas!
