Irritatingly I can't find it on their website - they don't seem to be featuring that segment - https://carteblanche.dstv.com/coming-26-march/

This study was a collaboration between a number of Universities but I don't remember seeing mention of the Einstein Institute.

So bizarre that I can't find reference of the segment, I'm going to try and contact them, I'll let you know if I find anything
