Editor's note

A large and potent component of language is our ability to communicate about things that are not here, that happened in the past, or that may happen in the future. But new research reveals that orangutans can also communicate about the past. Adriano Reis e Lameira explains the implications of this remarkable discovery.

The number of people switching to a vegan diet in the UK has risen fourfold in a decade. But this fast-growing trend is likely to become a major contributor to malnutrition in the West, argue Chris Elliott, Chen Situ and Claire McEvoy. If the trend continues, developed countries might need to follow developing countries and introduce large-scale bio-fortification programmes.

In many parts of the world, you are expected to love everything about Christmas. But some people hate it and feel under pressure to hide their feelings so they don’t ruin it for others. This can be a draining experience – but help is at hand. Karen Rodham, herself a Grinch, has written a Christmas survival guide for those dreading the festive season.

A computer may have been the size of room in 1968, but it was still a watershed year for the tech industry and Silicon Valley as we know it today. Find out why in our latest episode of The Anthill podcast.
