Working with colleagues on the other side of the world can mean a lot of challenges. There are differences in language, in time zone, in culture, even in the practise of doing science. But scientific collaborations, such as the one between Heather Viles’s team at University of Oxford in the UK and Qinglin Guo’s team at Dunhuang Academy in China, can also provide a wealth of benefits. In this documentary, the two teams reflect on making this ambitious project work and how other teams could do the same.

This documentary is part of a Nature special collection on collaboration. Read more here.
