Bionic flying penguin at science show
The best of the UK's cutting-edge science, engineering and technology are on display at London's Southbank Centre as the Royal Society opens its summer science festival.
The interactive exhibition answers questions including how body shape affects health, how researchers work out what is going on inside volcanoes and whether there is a new ocean opening up in Africa.
The festival, which runs until Sunday 4 July, is part of the society's 350th anniversary celebrations.
BBC News took a look around some of the attractions on display.
