A state of emergency has been declared in the US city of Ferguson, tensions escalated after an 18-year-old black man was shot by police after a demonstration against perceived police racism. Nick Bryant is in Ferguson.

“The police have said that the gun fight erupted between two rival groups, since that they were criminals rather than protesters. They’ve charged the 18-year-old shot by plain clothes officers with ten counts, five of armed criminal action and four of first degree assault on a law enforcement official. Tyrone Harris remains in a critical condition and his father claimed that the police's account of last night violence is a bunch of lies. Rather than firing on the police, he claims his son was unarmed and running for his life.”

Sunday's demonstration marks the first anniversary of the death of his friend Michael Brown, an unarmed black teenager, shot dead by a white policeman.

The Nigerian president Muhammadu Buhari has appointed a committee to advise him on the best way to tackle corruption and reform the legal system. Will Ross reports from Lagos.

"Corruption is a massive drain on Nigeria's public purse, so it is not surprising that president Muhammadu Buhari is seeking advice on how best to fight it. The seven-member anti-corruption committee is made up of academics and civil society activist who have a daunting task given the scale of the problem. In March, he made history by becoming the first ever opposition candidate wining an election in Nigeria. His stands on corruption was a key factor in that victory. So far, his talks tough on graft, the hard part would be uncovering it and genuinely eroding a crooked culture which is deeply engraved into many government departments."

Astronauts on the international space station have had their first bite from a lettuce grown in orbit. Gary O’Donoghue has more details.

“Astronauts have been growing crops in space for years. But this is the first time they've eaten the produce while still in orbit. It took the crew on the space station 33 days to grow the red romaine lettuce under LED lamps. Before they could eat the leaves, they had to wipe them with sanitizing clothe and then they add it a little oil and vinegar. 'The verdict: good stuff!' Said one of the crew. NASA believed its experiment will help develop ways of making crew self-sufficient for longer journeys to places such as Mars. For now, their judgement: one small bite for man, one giant leaf for mankind."

“宇航员们在太空种植作物已经多年了，但这是他们第一次在轨道上品尝所种植的物产。太空站上的宇航员花了33天的时间在LED灯下种出这种红叶生菜，在吃这种叶子之前，他们必须用消毒布擦干净，然后加上一点油和醋。一位宇航员说'味道很棒！'美国航天局称这次试验将帮助开发其他办法，让宇航员们能在到火星等更远的航行中实现自给自足。就目前来说，他们的看法是，这对宇航员来说是一小口的美味，但对人类来说是前进一大步。”
