Thank you. I was missing that info because I do not get that banner, currently surfing that site from the EU without any login.

Visiting the same URL on the .co.uk version gives me a multi-article scroller with different layout and links (including a "What is BBC Future?"), but no trace of that banner. Guessing that you're in the UK from your comment history, my best guess is that they decide whether to serve that banner via geofencing.
