Don't blame me for the headline, blame the telegraph.

The first hints of life on Mars have been discovered by Nasa.
Intriguing ‘burps’ of methane have been recorded by the Curiosity Rover which may have been produced by bacteria. Most methane on Earth is produced as a waste gas by living organisms.
Curiosity has previously found water bound in the fine soil of the Red Planet, believed to be crucial to life. But if the existence of living, breathing microbes is confirmed, it will be the first evidence of life outside Earth.
“What is interesting is that these spikes of methane are coming and going. They are transient,” said Dr Paul Mahaffy at Nasa.
“At the moment we can’t really tell anything, but these burps are intriguing. We have to keep an open mind.
“We don’t want to eliminate anything, and potentially it could indicate life or evidence of ancient methane trapped which could show ancient life.
“But it’s interesting to think about why it comes and goes. It seems to be suggestive of a localised source.”
Nasa claims that with more readings it would be possible to test isotope levels which would prove if the emissions came from a biological source.
