This week in Firstline's science chat, we're focusing on microbes – the good and the bad.
Scientists around the world have discovered how they can be used to diagnose cancer as well as protect us from asthma – but they can also cause disease.
AUT head of science research Steve Pointing says the study shows certain cancers show increases and decreases in different types of bacteria.
It means cancers could be diagnosed through something as simple as a saliva swab – but it could be a while before that happens regularly.
Elsewhere in science news, tests on mice show how exposure to healthy environments when young and in the womb can have life-long benefits.
