Reality Check: Erdogan visit amid tensions over Uighurs & possible purchase of Chinese missiles; news from the Large Hadron Collider.

Turkey and China

What is behind the state visit to China by the Turkish President Recep Tayyip Erdogan? He’s leading a group of businessmen, so is it all about economic relations between the two countries?

What about the recent anger in Turkey over China’s treatment of the Uighur minority the northwest, who have been restricted in practicing their Islamic faith, particularly during the holy fasting month of Ramadan?

Particle Physics

The Large Hadron Collider at CERN in Switzerland is the world’s largest and most powerful particle accelerator. It consists of a 27 km ring of pipes, in which two beams of particles are made to travel at close to the speed of light and then collide. The particles are so tiny that the task of making them collide is like firing two needles 10 km apart with such precision that they meet halfway. What happens when they do collide can tell the scientists more about what makes up the universe.

ATLAS Experiment, CERN 2015

Displays of a proton-proton collision event recorded by ATLAS on 21 May 2015.

The LHC was instrumental in the discovery of the Higgs boson, a subatomic particle that had long been theorized but never confirmed until 2013. Shortly after that it was closed down for maintenance and an upgrade, and on June 3rd this year the LHC was fired up again. The results so far are being discussed at a conference in Vienna. Joanna Bostock spoke to Professor Dave Charlton from the University of Birmingham and spokesman for the Atlas experiment at CERN about what's new:
