The chambered nautilus is a sea creature that belongs in the same class as the octopus. Unlike the octopus, it has a hard shell that’s divided into chambers. As the nautilus matures and grows, it ...

How does a species survive hundreds of millions of years unfazed? You must live in a shell – and it must grow with you, chamber by chamber Where to start with the nautilus: at the centre of the spiral ...

Learn about the optical rotatum, a newfound structure of light that exhibits a spiral pattern linked with various parts of nature. Patterns exist all around the world, creating unforgettable designs ...

Beams of light that can be guided into corkscrew-like shapes called optical vortices are used today in a range of applications. Pushing the limits of structured light, Harvard applied physicists in ...

Pushing the limits of structured light, physicists report a new type of optical vortex beam that not only twists as it travels but also changes in different parts at different rates to create unique ...
