So here's a question for you, do you know what the size effect of strength in materials is?

No, I didn't know but have now looked it up. Thanks.
Of course, the best I can now claim is that I know about the size effect. Not enough to know if the size effect invalidates part - or all - of the SciTechDaily article?

It does not invalidate the article, it invalidates the degree of hype that emerges around most "XYZ ultra-strong material developed" articles that come out on a fairly regular basis.
What's the "boring boomer bitcoin" version of some ultra-strong new material? That would be Toray's latest T1200 carbon fiber, with a stupendous tensile strength of 8 GPa, and it's a real thing being produced at scale that will be part of aerospace & defense supply chains -- I would not be surprised if the total output for some years has already been locked up mostly by Boeing and Airbus.
