A recent article in Guardian about the "ALH" Mars meteorite allegedly debunks the idea the meteor has fossilized Mars microbes. The article focuses on chemical analysis, but what about the microscopic "worms" they found in it? Organic chemistry doesn't always fossilize such that showing that the organic compounds could have a chemical (non-life) origin doesn't mean "the worms" were not living.
It's speculated the worm shapes were "carved" by magnetic forces instead of life, but the actual shape cause has never been settled to the best of my knowledge, and thus the worms are still an unsolved mystery.
