Astroinfo summarizes the new scientific research into the evidence of fossilized bacteria in the Mars rock

A group of scientists has been looking closer (literally, they’re using better electron microscopes than we had in 1996) at ALH 84001 for the last 13 years, and last month they published a paper claiming that the suggested geologic processes could not have made the formations found in the meteorite. In other words they disproved the disproof of their original hypothesis, which was that there was once life in this rock. Now, and this is very important to note, they do not claim to have found proof of life, or to have found indications of life. They simply claim that the possibility of a “biogenic origin” is once more back on the table.

The magnetite is argued to be too pure for non-life origins.

Martian Chronicles looks at the new Mars Rock analysis and research papers in detail.

It is possible that a fraction of the magnetite crystals are not inconsistent with life on Mars. Is this evidence for life on Mars? I give it a definitive “maybe”. It’s clear that the debate is far from over, and I expect to see some interesting rebuttal papers in the next few years. “Extraordinary claims require extraordinary evidence.” Right now I think the evidence is not extraordinary, but it may be getting there.
