Kate Adie introduces stories from Ghana's hospitals, the Chinese-Russian border, Syrian refugees in Lebanon, a research station on Australia's Great Barrier Reef and the streets of Limerick in Ireland.

Ghana is one of several African countries which say their health services are being sapped by a slow bleed of doctors and nurses going abroad - to earn vastly better salaries in the UK and elsewhere. Naomi Grimley spoke to medical staff in rural Kwaso and in the city of Accra about the push and pull factors on their minds.

After a drastic contraction during the periods of pandemic lockdown, China-Russia trade is on the rebound, and China's government is bullish about the prospects for recovery. At ground level things may not look so rosy. Ankur Shah reflects on the cross-border relations he saw reflected on the streets of the city of Manzhouli.

There's been a backlash in Lebanon against the hundreds of thousands of Syrian refugees still living in the country - twelve years after the start of the civil war in Syria. Recently there was an outcry over the case of a seven-year-old schoolgirl whose parents had been deported back to Damascus - while she sat in a Lebanese classroom. Carine Torbey went to meet her and hear her story.

The Great Barrier Reef is one of the most-studied coral formations on Earth - and Australia's government often claims that it's also one of the best-protected and best-managed. Marine scientists who've been working there over the long term have seen some changes, and are concerned about the future - especially if ocean temperatures continue to rise. Michelle Jana Chan hear about the state of the science on Lizard Island.

And: is keeping horses in a lockup garage in a major city - or driving them with two-wheeled carriages on a main road - a public nuisance, or a wholesome pastime? Bob Howard has been talking to the "sulky racers" of Limerick, and hearing why the sound of horses' hooves seems unlikely to disappear from Ireland's urban landscapes.
