This is interesting if it holds up. A group of scientists went back to the old Viking probe data from 1976; if you remember, the Viking lander had a scientific experiment designed to test for life in the soil of Mars. Back then, the tests were rather inconclusive, and the majority opinion was that the activity detected in the soil samples were geological in nature not biological.
Looking at the data three plus decades later, the researchers "found close correlations between the Viking experiment results' complexity and those of terrestrial biological data sets. They say the high degree of order is more characteristic of biological, rather than purely physical, processes."
In other words, they think there's still life on Mars.
The abstract for the paper is here, if you're interested in looking at this further.
