#5I need to make time to ask someone to ELI5 to me how this research is done without contaminating the sample with terrestrial-originated protein. The meteorite was on Earth for some time, and bacteria are staggeringly invasive little bugs.
I believe they successfully avoid contamination, but I have no idea how.

#6A team of researchers from Plex Corporation, Bruker Scientific LLC and Harvard University > has found evidence of there is a mismatch between the title of that article and the level of confidence these researchers were expressing.
the preprint is here:

#7Seems like this should be bigger news

sanitize a small sample then crack it open under cleanroom conditions to obtain an assumed pristine sample.
[edit] This is the full pdf below, if you look at page 2, you will see how they generated prepared and analyzed the sample

and this is the meteoritic report for the subject:

the thing with structured peer review is that noone knows it all , and a team of specialists [review commitee] are much more powerful than a team of generalists, to the end of revealing any artefacts of procedure, or hair splitting levels of knowledge regarding metalo-organic chemistry that could explain abiotic process that would produce amino acid polymerization.

An observer observing themselves is not data.
