I don't think Derek Lowe is frustrated that "science is full of fraud", this is likely editorialization on your part. It seems that it stems specifically from Masliah, who is common across all papers in the dossier. Granted, Masliah appears to be prolific, so this is admittedly a large issue in the peer review and verification structure in this field.

To put this into context though:

Let's begin by supposing that fraud exists in all ventures where people stand to gain, which I don't think is controversial at all, especially not in this comment section.

In light of this assumption the fact that this all came out in the first place is proof that being a luminary does not make you immune from investigation. That this happens 'over and over again' simply means that eventually we catching this fraud. The fact that the scientific community is constantly trying to reproduce and verify is why these become public in the first place.

So on the contrary, it's not that nothing ever happens or nothing ever improves. There will be articles like this one in twenty years because there will still be fraudsters in twenty years, and there will still be scientists working to verify their work.
