The US women's 400 metres champion Natasha Hastings happens to be a cousin of Shaka Hislop, the former West Ham goalkeeper who spent time working on the Space Station Freedom project at Nasa while studying mechanical engineering at Howard University, Washington. In the second semi-final of the women's 400m at the World Championships last night she blasted off at a frightening speed – only to find herself overtaken by a rocket in the shape of the Great Britain team captain.

The Diary: Cultural Olympiad; Roy Blackbeard; J D Salinger; Keira

Reflecting on the Cultural Olympiad – and the mystery surrounding the cultural programme for the 2012 Olympics – Alistair Spalding, the artistic director and chief executive of Sadler's Wells, Britain's premiere venue for contemporary dance, said he was a little worried at the lack of "big names" that had been confirmed to be taking part in the initiative. "They [the organisers] have left it quite late. The artists I'm engaged with are already involved in their own activities, their diaries are filling up... I imagine it is going to be a challenge, because it's quite late in the day." He suggested that it might be better – for programming, at least – to "move the Olympics to 2013"! Tony Hall, meanwhile, who is the chair of the Olympiad, said discussions with artists were taking place, and that an announcement of who would take part was imminent over the next few months. The Olympiad, he said, was going to change its name, adding that it would prove to be the "festival of festivals". We await further details.
