On Dear Science today we talk about the end of the Opportunity Rover on Mars, push ups and heart disease, and the best order to drink wine and beer together as well as a profile of the element Americium from the Periodic Table.

Fletcher Tabuteau is with us this week and Lillian Hanly spoke with him about the Digital Services Tax and the possible shift away from the use of 1080.

Finally, Lillian has something special in store for Wednesday listeners over the next month or so, and that is A Seven Part Chat with Rod Oram. This will be explained later in the show but basically there were some articles around the possibility of another global financial crisis and Lillian wanted to know more about that, and whether we should be keeping money out of the bank... 

Heaps of great interaction from listeners today too with lots of good points about alcohol poisoning and tax and fairness.
