Soap Bubble Structures by Kym Cox. Bubbles optimise space and minimise their surface area for a given volume of air. This phenomenon makes them a useful tool in many areas of research, in particular, materials science and “packing” – how things fit together. Bubble walls drain under gravity, thin at the top, thick at the bottom, which interferes with travelling lightwaves to create bands of colour. Black spots show the wall is too thin for interference colours, indicating the bubble is about to burst. (Photo by Kym Cox/2019 Science Photographer of the Year/RPS)

They might look like something straight out of a horror film, but these extraordinary images have been created to show the special bond between cats and their owners. Photographer Sebastian Magnani, 28, from Brig, Switzerland, took pictures of dogs and their owners using the same position and camera settings before working his magic with editing software. The result is this startling set of images, which show the pooches with human clothes – one wearing a hoodie, another with a red coat, one with a shirt and cardigan, and another with a blue jacket.
