Alien bacteria turns out to be iron deposits

What was thought to be fossilised bacteria in a meteorite has turned out to be something more mundane.

The find echoes the alleged discovery of fossilised micro-organisms in a Martian meteorite that turned out not to be. "'It was a good lesson in trusting your data over what you’d been told you should find," said Professor Alison Marshall who was part of the team that re-examined the rock. "At every step of the way, we would do an experiment expecting to find one result and find the complete opposite instead."

"It was a discovery that scientists proclaimed was the oldest evidence of life on our planet."

Next NASA will say the only position he ever held was a janitor and that the bio on the NASA site was a typo.

I`ll stand behind this man If He can make that worm do a trick! But then again there are lots of brilliant men and women that have no stinkin phd`s! Can anyone say otherwise?

Clearly 'worms' can do some serious 'tricks'. The question is do they need a 'Planet' like the young Earth or does a Comet or pre-cometary matter suffice? If both or just the latter then the Comet's are older. The heavy elements we find on Earth are certainly billions of years older than the solar system itself. The Organic matter must also be very old considering we see it present throughout the Universe.

Well I think it's exciting! If we can happen upon bacteria from 'off-world' the implication is there that life maybe well be very frequent in the universe.

Whoops! Scientists left red-faced as oldest 'evidence of life' turns out to be iron deposits. It was a discovery that scientists proclaimed was the oldest evidence of life on our planet. But researchers who thought they had found 3.5 billion-year-old bacteria fossils in Australian rock have been left red-faced after U.S geologists debunked their findings. A team from the University of Kansas said the microscopic structures are nothing more than tiny gaps in the rock that are packed with lifeless minerals.

Not scientists, technically Dr. Hoover is an engineer. We've already gone through the evidence as related to his research, the faultiness of it and the poor quality of the journal he published in. Edit: Wait, the article doesn't bear much relation to this thread.

Hey there, I'm still not sure I've seen good support of the claim in faultiness of this research or poor quality of the journal. I realize the journal is a supporter of panspermia therefor bias may come into play but what else is there? Is there something that I have missed? Thanks Edit to add: Also I found it interesting that NASA, last week, appointed a "Planetary Protection Officer" who's job it is to ensure that alien microbes do not contaminate earth nor earth microbes contaminate other planets...after firmly dismissing Dr. Hoover's claim.

I'd recommend reading the reports I posted. Chiefly, there's a couple of main critiques: The extreme likelihood, even if there is evidence of bacteria, of contamination. Second, the scale we're looking at is much above the level of bacteria, and is instead looking at a level where things like tin whiskers are common. Third, the journal is not under attack because of it's support of panspermia, a theory that still gets tossed around in scientific discourse fairly often, but instead that the journal is the singular work of it's editor, with very poor quality controls...

Maybe they were bionic bacteria?
