Life on Mars is hot

New Scientist: A whiff of life on the Red Planet

Continuing a theme from the previous post:

Now [European Space Agency scientist Vittorio] Formisano is saying that there is much more methane on Mars. He bases this on the detection of a different gas, formaldehyde, by the Planetary Fourier Spectrometer (PFS), an instrument on Mars Express that he runs. Formisano averaged thousands of measurements taken by the PFS and calculated that the Martian atmosphere has formaldehyde in concentrations of 130 parts per billion.
