This episode Jesse and Harry talk ants and tech: CSIRO's phenomenally successful eradication of African big-headed ants from Lord Howe Island. Good lord, how!? Cat food. Poisonous cat food. They also chat about autonomous cave-exploring droids and also speak with star researcher Dr Elizabeth Mahony about interstellar radio explosions, Fast Radio Bursts, and the newly isolated origins of one in particular.
