Goats climb on students during a yoga class with eight students and five goats at Jenness Farm in Nottingham, New Hampshire, U.S. on May 18, 2017. Tucked away in a wooded corner of southern New Hampshire, Jenness Farm is the latest small U.S. agricultural operation to cash in on the social media-driven trend, in which yoga enthusiasts practice moves like the cat pose and bridge pose while goats climb around and sometimes on them.

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)
