Very few people have heard of Detective Sergeant Dion Achtypis - but there may well be no more important investigator in Australia.

You won’t see him holding a press conference at a murder scene or commanding a squad of detectives. And he doesn’t use a sledgehammer during raids - he gains access in a much more subtle way. He is part of a three-person team working in the present while exploring the future.

Cyber cop Dion Achtypis sits down with John Silvester to discuss Bitcoin, international crime syndicates and the Underbelly series.

Cardiac Cowboys

Cardiac Cowboys

The heart was always off-limits to surgeons. Cutting into it spelled instant death for the patient. That is, until a ragtag group of doctors scattered across the Midwest and Texas decided to throw out the rule book. Working in makeshift laboratories and home garages, using medical devices made from scavenged machine parts and beer tubes, these men and women invented the field of open heart surgery. Odds are, someone you know is alive because of them. So why has history left them behind? Presented by Chris Pine, CARDIAC COWBOYS tells the gripping true story behind the birth of heart surgery, and the young, Greatest Generation doctors who made it happen. For years, they competed and feuded, racing to be the first, the best, and the most prolific. Some appeared on the cover of Time Magazine, operated on kings and advised presidents. Others ended up disgraced, penniless, and convicted of felonies. Together, they ignited a revolution in medicine, and changed the world.
