09:05  Investigative journalists claim matchfixing rife at top levels of tennis
The investigation by BuzzFeed News and the BBC  is based on a cache of leaked documents from inside the sport, interviews with whistleblowers, officials, players and match fixing experts. The investigative journalists have revealed gambling syndicates in Russia and Italy have placed suspicious bets on tennis matches - including at Wimbledon and the French Open and that tennis players are being targeted in hotel rooms at major tournaments and offered tens of thousands of dollars to fix their match.

John Templon of Buzzfeed is one of the investigative journalists behind the story.

09:15 Saudi Arabia-Iran Feud 'carries implications for all of us'.

James B. Smith, a former U.S. Ambassador to Saudi Arabia (from 2009 to 2013) examines the diplomatic fallout of supercharged tensions between Saudi Arabia and Iran, and how they impact on the geo-political situation in the Middle East.

It follows the Saudi execution of a Shia Muslim cleric, the subsequent setting ablaze of the Saudi embassy in Tehran, Riyadh's expulsion of Iranian diplomats and Tehran accusing Saudi warplanes of bombing its embassy in Yemen, where Saudis and Iranians are involved on opposite sides of the country's civil war.

James B. Smith is also a  former U.S. Air Force brigadier general and F-15 fighter pilot who served in Operation Desert Storm. He is currently the president of C&M International, an economic and political consulting firm.

The former Ambassador says he doesn't expect the crisis to escalate into conflict, but it does impact negatively on future prospects for Syria and Yemen, and that has implications for all of us.

09:30 NZ Heart Modelling Research Fights World's Major Killer

In New Zealand cardiovascular disease (heart, stroke and blood vessel disease) is still the leading cause of death, accounting for 30% of deaths annually.

Nick Smith from the University of Auckland is working with research teams in the UK, to build individualised computer models of heart patients' blood flow before surgery to show which pipes should be unblocked.  This makes surgery faster, cheaper, and more effective, with a potential reduction in secondary surgery, known as Type 2 failures, of up to 50%.

These same modelling techniques, known as 'cardiac physiome' can also be applied to heart arrhythmia, specifically pacemakers. Taking an MRI image, Nic and his team are able to tell the surgeon exactly where the pacemaker should go and are able to reduce the failure rate to around 15% by doing the modelling work first. 

Nick Smith is the Dean of Engineering at the University of Auckland, a professor of bio-medical engineering at Kings College London, and a visiting professor of computational physiology at the University of Oxford.

from 'Took the Children Away'

This story’s right, this story’s true, 
I would not tell lies to you
About the promises they did not keep, 
How they fenced us in like sheep
Said to us come take our hand, 
Set us up on mission land
Taught us to read and write and pray, 
Then they took the children away
Snatched from their mothers breasts, 
Said this is for the best
Took them away…
