So this is getting interesting (following on from the failed replication study (posted here).

Quick Notes:

• This is a simulation! So it lends credence to the possibilities of this being legit.
• But it’s from an apparently credible lab
• This line struck me as consistent with the difficulties people have been having with replication (from the twitter summary):

This means the material would be difficult to synthesize since only a small fraction of crystal gets its copper in just the right location.
