Carp herpes, Noisy miners, Canadian wildfires and diagnosing Parkinson's disease

Chris talks about two problem species: carp, which is about to be given herpes by Barnaby Joyce, and Noisy miners, which are native birds that drive out other species. Also, Manisha talks about the recent Canadian wildfires that are so big they create their own weather systems, and Stu interviews microbiologist Paul Fisher who works with a team at Latrobe University including Dr. Sarah Annesley and Dr. Danuta Loesch, about finding mitochondrial biomarkers for early diagnosis of Parkinson's disease.http://minister.agriculture.gov.au/joyce/Pages/Media-Releases/cleaning-australia-waterways.aspx
