Hosts: Ed Brown, Dr. Shayne Joseph and Penny Dumsday.
A portable plasma gun that zaps bacteria, the ability to identify a person from their RNA, and the risk of brain tumours from dental x-rays. The Japanese honeybee giant ball of death, and how evolution copies itself. A build up of carbon dioxide ended the last ice age, and why hyenas are giving up meat for Lent.
