Konstantin Buteyko, Soviet doctor

Konstantin Pavlovich Buteyko (1923-2003), Soviet medical doctor and researcher. In the 1950s, Buteyko, a Ukrainian, developed a theory on the effects of deep breathing (hyperventilation). He believed that diseases such as asthma are caused by a drop in carbon dioxide blood levels brought on by hyperventilation. Buteyko said that shallow breathing restores these levels to normal. He established a laboratory in Siberia, treating over 1000 people in the 1960s, despite attempted Soviet suppression. The Buteyko method is controversial; sceptics say it works because of a psychological (placebo) effect. Photographed in 1987

Emperor penguin chicks huddling

Emperor penguin (Aptenodytes forsteri) chicks huddling for warmth in the Antarctic spring. These grey-feathered chicks are about one month old. The adults feed them by regurgitating fish. These are the only penguins to breed in the Antarctic during the winter. Each pair produces a single egg, which the males incubate on their feet, surviving the extreme cold by huddling in large groups. Males fast during the two month incubation period and lose almost half their body mass by the end. The emperor is the largest penguin, standing around 115 centimetres tall and weighing 30 to 40 kilograms. Photographed in September at Dawson-Lambton Glacier, Antarctica
