> The world's thinnest spaghetti, about 200 times thinner than a human hair, has been created by a UCL-led research team. The spaghetti is not intended to be a new food but was created because of the wide-ranging uses that extremely thin strands of material, called nanofibers, have in medicine and industry.

This is a fantastic first paragraph, which unfortunately is not the norm. It succinctly explains what was created (world's thinnest spaghetti), the scale at which it is impressive (200 times thinner than a human hair), who did it (a UCL-led research team), and why it matters (the second sentence) while simultaneously explaining what it is not for that most people would think about.

It’s impossible to provide every minute detail in one short paragraph, but that one is dense with information, clear, and gives you an immediate sense if the article is of interest to you.

Kudos to the University College London. Though I’d like to be more specific and know exactly who wrote/edited that.
