Possible fossils found in meteorite fragments? MAR 11 2013
Well, here's something potentially interesting: researchers at Cardiff University think they have found fossils in meteorite fragments from Sri Lanka.
The most startling claims, however, are based on electron microscope images of structures within the stones (see above). Wallis and co say that one image shows a complex, thick-walled, carbon-rich microfossil about 100 micrometres across that bares similarities with a group of largely extinct marine dinoflagellate algae.
They say another image shows well-preserved flagella that are 2 micrometres in diameter and 100 micrometres long. By terrestrial standards, that's extremely long and thin, which Wallis and co interpret as evidence of formation in a low-gravity, low-pressure environment.
Gotta take this with a massive grain of salt, but it will be interesting to see how this one plays out.
Update: One of the authors of this study holds some unusual views about life on Earth.
On May 24, 2003 The Lancet published a letter from Wickramasinghe, jointly signed by Milton Wainwright and Jayant Narlikar, in which they hypothesized that the virus that causes Severe Acute Respiratory Syndrome (SARS) could be extraterrestrial in origin and not originated from chickens.
Wickramasinghe and his mentor Fred Hoyle have also used their data to argue in favor of cosmic ancestry, and against evolution.
Like I said, big grain of salt. (thx, onno)
