In November 1994, the Russian conceptual artist Oleg Kulik posed in front of an art gallery in central Moscow, naked, pretending to be a guard dog and attacking passers by. It was his way of highlighting the fact since the collapse of the USSR three years earlier, Russians had lost their ability to relate to each other, and were reduced to living like animals. Dina Newman speaks to Kulik about his protest performance, which made him famous around the world.

One of the most potentially dangerous legacies of the collapse of the Soviet Union was its huge nuclear arsenal and nuclear weapons industry. There were particular concerns about the Soviets' former nuclear testing site at Semipalatinsk in Kazakhstan, a vast swathe of contaminated land where there were tunnels with spent plutonium. When the Soviet Union ended, the site was left open to scavengers. Louise Hidalgo has been hearing from the former head of America's nuclear weapons laboratory, Dr Siegfried Hecker, about the long secret operation by Russian and American scientists to make the site safe in what's been called the greatest nuclear non-proliferation story never told.
