Regarding the whole room-temperature superconductor thingie, I am still quite skeptical, in good part due to how badly-structured, written and consistent the original article is - something I am able to say based on my curriculum and experience - however I will leave the final conclusion to the better-equipped and more experienced labs who are now apparently working on the stuff. Because they are experts in the field and I am not.
As a recommendation for those following this, don't get too excited and give it a few weeks or months, this is usually how long it can take for definitive results to come in research.
