Lake Vostok, which has been sealed off from the world for 14 million years, is about to be penetrated by a Russian drill bit.
The lake, which lies 2.5 miles below the icy surface of Antarctica, is unique in that it’s been completely isolated from the other 150 subglacial lakes on the continent for such a long time. It’s also oligotropic, meaning that it’s supersaturated with oxygen: Levels of the element are 50 times higher than those found in most typical freshwater lakes.
Researchers explore atmospheric history with giant insects
Researchers at Arizona State University have been conducting experiments to test how oxygen-enriched atmospheres affect evolution, creating giant dragonflies and tiny cockroaches in the process.
In fossil record, there's evidence of enormous insects with wingspans of up to 70 centimetres. The explanation usually given for such creatures is that the Earth's oxygen levels were considerably higher in the past. It's believed that at some points in history, oxygen accounted for as much as 31 percent of the atmosphere, compared to around 21 percent today. It's plunged as low as 12 percent at points, too.

Thanks for the reply, I've just realised there's an existing thread in Fragile Earth
Maybe mods can lock this so that people can direct to the conversation... I don't want to cause friction

As the scientists say it's going to provide an evolutionary snap shot of what earth was like all those years ago, untainted by man.. and I just can't wait to see some of the first results.
