Editor's note

We’re used to reading about artificial intelligence being used to answer questions or drive cars. We’ve heard AI could even listen and then perform simple households tasks. But Andrea Soltoggio writes that he is developing AI that can smell. The hope is that in the future AI will be able to detect illnesses, such as cancer, just from catching a whiff of human breath.

Relations between Donald Trump and Justin Trudeau went into deep freeze over the weekend, with the American G7 delegation accusing the Canadian PM of “stabbing them in the back” and promising “a special place in hell” for him. Have things been this chilly in North America since 1812? Trump made a joke about the conflict of that year in the run-up to the summit. Here, courtesy of our colleagues in Toronto, Renée Lafferty-Salhany looks at what Trump – and many others – don’t know about an often forgotten war.

With all the discussion over plastic pollution in the ocean, you might have heard reports about the number of microplastic particles that can end up in the seafood on our plates. But it’s also finding its way into honey, water and beer. Christina Thiele and Malcolm Hudson report.

Kanye West has announced his intention to be “one of the biggest real-estate developers of all time”, and his starting point appears to be a neo-Brutalist style, low income housing project based in California. But Nick Dunn writes that cities must be designed with people – not just for them.
