The World Economic Forum at Davos this week has been dominated by speculation about how the US president, Donald Trump, may be planning to fulfil his ambition to control Greenland. In the end he backed down from the threat of force against Denmark and its European partners while stepping up his demand to take control of the island.
However, this Davos may end up remembered for pitting Trump against the leader of another once-firm ally: his northern neighbour Mark Carney, the prime minister of Canada. International affairs scholar Mark Shanahan watched them both speak and delivers his verdict here.
Also today: horses really can smell when their rider is fearful and it affects the animals’ behaviour, according to a new study. And the strange tale of an experiment which aimed to shed light on how people pass on influenza, but that ended with no one contracting the virus.
