Freezing the moment

A clear top from the top

The article describes the construction of the British Airways i360 tower in Brighton. It is the world’s tallest moving observation tower whose capsule is based on an ‘oblate ellipsoid’ and is ten times bigger than a single London Eye capsule and is 18 metres in diameter. 

Jaws of a shark

This article looks at the career and interests of Dr Gareth Fraser who has been interested in marine biology since he was a child. Dr Fraser describes how this interest is leading to surprising possibilities in the field of human dentistry.

From small seeds to big yields

The article looks at the process of domestication which led to a natural increase in traits such as grain size (increasing calories available), grain accessibility, an increased number of grains and the loss of a hard protective coating.

Six views of Mercury

This article presents six different images of Mercury, the planet nearest the Sun. Mercury has been visited by two probes. The most recent, Messenger, orbited the planet 4000 times in four years before crashing into its surface on 30 April 2015. Like the maps in an atlas of the Earth, the images in the article are coloured to highlight different aspects of Mercury’s surface.
