With tensions running high in Ukraine, the US has today ordered the families of embassy staff to leave the country. Our bureaux have been producing a series of articles outlining the issues at play and possible scenarios that could unfold. For instance the piece below by Julien Théron at Sciences Po assesses the military picture, but all our coverage can be viewed here, and it will, of course, update as the fast moving situation continues to develop.

Elsewhere, our authors consider the establishment of a National Resting Place in Australia and the attempts of Jeff Bezos and others to extend the human lifespan. Have a great week – we’ll be back in your inbox on Thursday. But if you can’t wait until then, do keep an eye on the network’s Global homepage for a selection of content from across our editions.
