Change of air: how rising levels of oxygen transformed life on the land

The solution came from other forms of life that had emerged on land. A few small, worm-like creatures probably emerged from the sea at about the same time as the earliest plants and mosses, about 420 million years ago.

Gas blast destroys flats in Ukraine

An explosion ripped through an apartment building in southern Ukraine, killing 19 people. A further 24 people are still unaccounted for, and officials expect the death toll to rise. Twenty-one residents were pulled out alive from the five-storey block in the Black Sea resort of Yevpatoria. The blast, probably caused by canisters of oxygen stored in the basement, flattened all five floors, leaving rubble several metres high strewn with wires, smashed furniture and personal possessions. "As I was walking by, I heard a bang, and then I saw this building crumble," one witness said. Another, who lived opposite the apartment block, said: "We heard a terrible bang. We thought our balcony crashed because of the way the windows vibrated. But when I went on to the balcony I saw smoke from the other side." President Viktor Yushchenko and the Prime Minister, Julia Tymoshenko, set aside their feuding to arrive at the scene together. Mr Yushchenko declared today a national day of mourning. Casualties caused by gas blasts in often crumbling apartment buildings are common occurrences in former Soviet republics, particularly in winter when residents use more heating. Reuters

Simon Calder: Low pressure in the skies leads to high anxiety

Four out of five British travellers say they could walk alone and unaided to the North Pole with nothing more substantial than a chunky-knit jumper and a pocket full of Kendal mint cake. Even by the standards of some of the travel surveys that emerge during the dog days of August, that is tosh. But how about the statistic that was cited in the aftermath of a diverted Ryanair flight this week? "Well over 80 per cent of people on that flight knew they were going to die."
